You have one dollar bills and five dollar bills totaling 45 dollars.
You have 4 times as many one dollar bills as you do five dollar bills. How many
of each type of bill do you have?

Answer:

176 + 5x = 651

Step-by-step explanation:

the parts are 176, the guy works for 5 hours and the total is 651. the hourly cost is the unknown so 176 + 5x = 651.

hope this helps

Answer:

x=95

Step-by-step explanation:

The equation to solve this would be 651=176+5x. The first step would to subtract 176 on both sides of the equation. 651-176=176-176+5x. That equals 475=5x. Now, to isolate the variable, divide both sides of the equation by 5. 475/5=5x/5 That gives you 95=x. The cost of labor per hour is $95.

Answer:

A

Step-by-step explanation:

Using Work problem solving , we get

Matilde could take 90 minutes to complete the research project alone .

Raphael could take 3 hr to complete the research project alone.

Work problems are fraction problems :

the following is a simple equation we could use in solving work problems :

1/t₁ + 1/t₂ = 1/td ---> (*)

where,

t₁ = the time it takes for one person to do the work alone

t₂ = the time it takes for the other person to do the work alone

td= the time it takes to do the work when two people are working together.

Now, it is given that matilde twice as long to complete a research project as it takes raphael to do the same research project. They worked together and they could finish similar project in 1 hour.

Let t₁= the time that takes the Raphael working alone

and t₂ = 2t₁= the time it takes for research project working alone

td = times taken by both of researchers to complete the research project together = 1 hr

Now, put the values in above equation (*) we get,

1/t₁ + 1/(2t₁) = 1/1 = 1

Now, we just need to solve for t₁ to get the time it takes for finish the research project work alone.

3/2t₁ = 1 => t₁ = 3/2 hr or 90 minutes

if t₁= 3/2 then t₂ = 2× 3/2 = 3 hr

Hence, matilde will take 3 hr to finish the research project alone and Raphael will take 90 minutes to finish the project work alone.

Step-by-step explanation:

someone else asked the same question here! https://brainly.com/question/30091724

there are better explainations there :)

you're looking for the perimeter, so you need to add all the sides. that's 55+55+98+98, which is 306.

For the sample of soil given a) the porosity is 100.4%; b) the specific yield is 12.2%; c) the specific retention is 14.6%; d) the void ratio is 0.5342; e) the initial moisture content is 2.3%; and f) the initial degree of saturation is 41.97%.

a) The porosity of soil can be defined as the ratio of the void space in the soil to the total volume of the soil.

The total volume of the soil = Initial volume of soil = 100 c.m³

Weight of water added to the soil = 234.6 g – 220 g = 14.6 g

Volume of water added to the soil = 14.6 c.m³

Volume of soil occupied by water = Weight of water added to the soil / Density of water = 14.6 / 1 = 14.6 c.m³

Porosity = Void volume / Total volume of soil

Void volume = Volume of water added to the soil + Volume of voids in the soil

Void volume = 14.6 + (Initial volume of soil – Volume of soil occupied by water) = 14.6 + (100 – 14.6) = 100.4 c.m³

Porosity = 100.4 / 100 = 1.004 or 100.4%

Therefore, the porosity of soil is 100.4%.

b) Specific yield can be defined as the ratio of the volume of water that can be removed from the soil due to the gravitational forces to the total volume of the soil.

Specific yield = Volume of water removed / Total volume of soil

Initially, the weight of the oven dried soil is 220 g. After allowing it to drain by gravity, the weight of soil is 222.4 g. Therefore, the weight of water that can be removed by gravity from the soil = 234.6 g – 222.4 g = 12.2 g

Volume of water that can be removed by gravity from the soil = 12.2 c.m³

Specific yield = 12.2 / 100 = 0.122 or 12.2%

Therefore, the specific yield of soil is 12.2%.

c) Specific retention can be defined as the ratio of the volume of water retained by the soil due to the capillary forces to the total volume of the soil.

Specific retention = Volume of water retained / Total volume of soil

Initially, the weight of the oven dried soil is 220 g. After adding water to the soil, the weight of soil is 234.6 g. Therefore, the weight of water retained by the soil = 234.6 g – 220 g = 14.6 g

Volume of water retained by the soil = 14.6 c.m³

Specific retention = 14.6 / 100 = 0.146 or 14.6%

Therefore, the specific retention of soil is 14.6%.

d) Void ratio can be defined as the ratio of the volume of voids in the soil to the volume of solids in the soil.

Void ratio = Volume of voids / Volume of solids

Initially, the weight of the oven dried soil is 220 g. The density of solids in the soil can be calculated as,

Density of soil solids = Weight of oven dried soil / Volume of solids

Density of soil solids = 220 / (100 – (14.6 / 1)) = 2.384 g/c.m³

Volume of voids in the soil = (Density of soil solids / Density of water) × Volume of water added

Volume of voids in the soil = (2.384 / 1) × 14.6 = 34.8256 c.m³

Volume of solids in the soil = Initial volume of soil – Volume of voids in the soil

Volume of solids in the soil = 100 – 34.8256 = 65.1744 c.m³

Void ratio = Volume of voids / Volume of solids

Void ratio = 34.8256 / 65.1744 = 0.5342

Therefore, the void ratio of soil is 0.5342.

e) Initial moisture content can be defined as the ratio of the weight of water in the soil to the weight of oven dried soil.

Initial moisture content = Weight of water / Weight of oven dried soil

Initial weight of soil = 225.1 g

Weight of oven dried soil = 220 g

Therefore, the weight of water in the soil initially = 225.1 – 220 = 5.1 g

Initial moisture content = 5.1 / 220 = 0.023 or 2.3%

Therefore, the initial moisture content of soil is 2.3%.

f) Initial degree of saturation can be defined as the ratio of the volume of water in the soil to the volume of voids in the soil.

Initial degree of saturation = Volume of water / Volume of voids

Volume of water = Weight of water / Density of water

Volume of water = 14.6 / 1 = 14.6 c.m³

Volume of voids in the soil = 34.8256 c.m³

Initial degree of saturation = 14.6 / 34.8256 = 0.4197 or 41.97%

Therefore, the initial degree of saturation of soil is 41.97%.

Answer:

B

Step-by-step explanation:

We will divide 18 by 3 and 30 by 5, and if the results are the same, then this relationship is proportional.

18/3 = 6

30/5 = 6

The two answers are the same, so this relationship is proportional.

The required return for a stock with a beta of 2.20, a risk-free rate of 2%, and a market risk premium of 6% is 14.39%.  The correct option is c.

To calculate the required return, we can use the Capital Asset Pricing Model (CAPM), which relates the expected return of a stock to its beta, the risk-free rate, and the market risk premium. The formula for CAPM is as follows:

Required Return = Risk-Free Rate + (Beta × Market Risk Premium)

In this case, the risk-free rate is 2% and the market risk premium is 6%. The beta of the stock is given as 2.20. Plugging these values into the formula, we get:

Required Return = 2% + (2.20 × 6%) = 2% + 13.2% = 15.2%

Therefore, the correct answer is option C: 14.39%.

The CAPM is a widely used model in finance to estimate the required return on an investment. It takes into account the risk-free rate, which represents the return on a risk-free investment such as government bonds, and the market risk premium, which represents the additional return investors expect to receive for taking on the risk of investing in the overall market.

The beta of a stock measures its sensitivity to market movements, and multiplying it by the market risk premium gives us an estimate of the stock's additional required return. By summing this additional return with the risk-free rate, we obtain the required return for the stock.

When he finally looked at the clock, he saw that it was already -3 degrees outside and he had to be at school in 7 minutes!

Panicking, Jack quickly shut off his game and raced to get dressed. He grabbed his backpack and ran out the door, but as he was running down the street, he realized that he had forgotten his math homework at home. Frustrated and upset, Jack thought to himself "I can't believe my score was -3 and now I'm going to be late to school by 7 minutes."

As he walked into class, he apologized to his teacher for being late and explained the situation. His teacher, understanding the predicament, gave him an extra 7 minutes to complete his math homework during class. Jack was relieved and grateful, and he made sure to always keep track of time while playing his video games.

From that day on, Jack made a promise to himself to balance his love for gaming and his responsibilities, and he kept a close eye on the clock. He knew that being -3 minutes late and +7 minutes early was the key to success in both his gaming and his studies.

The probability that a given class period runs between 50.5 and 51.25 minutes is 15%.

Probability defines the likelihood of occurrence of an event. There are many real-life situations in which we may have to predict the outcome of an event. We may be sure or not sure of the results of an event. In such cases, we say that there is a probability of this event to occur or not occur. Probability generally has great applications in games, in business to make probability-based predictions, and also probability has extensive applications in this new area of artificial intelligence.

The probability of an event can be calculated by probability formula by simply dividing the favorable number of outcomes by the total number of possible outcomes. The value of the probability of an event to happen can lie between 0 and 1 because the favorable number of outcomes can never cross the total number of outcomes. Also, the favorable number of outcomes cannot be negative.

\(P(50.5 < = X < = 51.25) =\frac{51.25-50.5}{54-49 } = \frac{0.75}{5} = 0.15\)

P = 0.15 means that the probability is 15%.

Thus, the probability that a given class period runs between 50.5 and 51.25 minutes is 15%.

Electric field due to Q1 is 27/10 N/C, electric field due to Q2 is -54/10 N/C and electric field at A due to Q1 is 2.32454 N/C.

Given,

Q1 = 3nCQ2

     = -6nC

The distance between them is 0.1 m. (10^2m)

The electric field due to a charge is given by κQ/r^2

Where Q is the charge,

            r is the distance,

            and κ is a constant.κ = 9 x 10^9 Nm^2/C^2

Electric field due to Q1 =κQ1/r^2

                                       =9 x 10^9 x 3 x 10^-9/ (0.1)^2

                                       = 27/10 N/C

At point A due to E1 = Electric field at point A due to Q1 = E1x i + E1y j + E1z k.

Since the point A is (-0.07, -0.04, 0), so we have to calculate the electric field at point A due to Q1 on the x-axis, y-axis and z-axis respectively.

Therefore, E1x = E1cosθ, E1y = E1sinθ, E1z = 0

Where θ is the angle that E1 makes with the x-axis.

Tanθ= 0.04/0.07

        = 0.5714θ

        = 30.9638°

Now, E1x = E1cosθ

                = 27/10 x cos30.9638°

                = 23.2454/10 N/C

And E1y = E1sinθ

               = 27/10 x sin30.9638°

               = 13.3935/10 N/C

So, E1 = E1x i + E1y j + E1z k

           = 23.2454/10 i + 13.3935/10 j + 0 k

           = (2.32454, 1.33935, 0) N/C, at point A due to Q1.

Electric field due to Q2 = κQ2/r^2

                                       = 9 x 10^9 x (-6 x 10^-9)/ (0.1)^2

                                       = -54/10 N/C, at point A due to Q2.

E2 = Electric field at point A due to Q2= E2x i + E2y j + E2z k

Since the point A is (-0.07, -0.04, 0), so we have to calculate the electric field at point A due to Q2 on the x-axis, y-axis and z-axis respectively.

Therefore, E2x = E2cosθ, E2y = E2sinθ, E2z = 0

Where θ is the angle that E2 makes with the x-axis.

Tanθ = 0.04/0.07

         = 0.5714θ

         = 30.9638°

Now, E2x = E2cosθ

                = -54/10 x cos30.9638°

                = -46.491/10 N/C

And E2y = E2sinθ

               = -54/10 x sin30.9638°

               = -26.7872/10 N/C

So, E2 = E2x i + E2y j + E2z k

            = -46.491/10 i - 26.7872/10 j + 0 k

            = (-4.6491, -2.67872, 0) N/C, at point A due to Q2.

Net Electric field at point A,En→1 = E1+E2

                                                      = (2.32454, 1.33935, 0) + (-4.6491, -2.67872, 0)

                                                      = (-2.32456, -1.33937, 0) N/C, at point A.

Step-by-step explanation:

The side lengths of an equiangular octagon are 1, 2, 3, 4, 1, 2, 3, and 4 in clockwise order so area of octagon is 11 + 12√2 square units.

The sides of octagon are 1, 2, 3, 4, 1, 2, 3, 4 as shown in the figure,

The area of the octagon = area of the rectangle - the area of the four right isosceles triangular corners.

A = (lxb) - 1/2[√2×√2 + √8×√8]x2

A = [(3+√2+√8)(1+√2+√8)] -1/2[√2×√2 + √8×√8 + √2×√2 + √8×√8]

A = 3 + 12√2 +7

A = 11 + 12√2

Therefore, The area of the octagon is 11 + 12√2 square units.

A closed two-dimensional shape having eight sides, eight vertices, and eight internal angles is known as an octagon.
