It takes Katie 30 minutes to get to work. Write an equation to determine how many minutes it takes Mina to get to work. 30 = one halfx + 10 30 = one halfx − 10 30 = 2x − 10 30 = 2x + 10

Answers

Answer:

Simplifying

2x + -10 = 10 + -3x

Reorder the terms:

-10 + 2x = 10 + -3x

Solving

-10 + 2x = 10 + -3x

Solving for variable 'x'.

Move all terms containing x to the left, all other terms to the right.

Add '3x' to each side of the equation.

-10 + 2x + 3x = 10 + -3x + 3x

Combine like terms: 2x + 3x = 5x

-10 + 5x = 10 + -3x + 3x

Combine like terms: -3x + 3x = 0

-10 + 5x = 10 + 0

-10 + 5x = 10

Add '10' to each side of the equation.

-10 + 10 + 5x = 10 + 10

Combine like terms: -10 + 10 = 0

0 + 5x = 10 + 10

5x = 10 + 10

Combine like terms: 10 + 10 = 20

5x = 20

Divide each side by '5'.

x = 4

Simplifying

x = 4

Answers

Here are the pairs matched with their products:

- (-5)(4.2) matches with -21

- (-7)(-3) matches with 21

- (2.5)(-9) matches with -22.5

Pairs (4) and (5) do not have corresponding products in the given options.

The products of the given pairs of numbers are:

(-5)(4.2) = -21

(-7)(-3) = 21

(4)(5) = 20

(2.5)(-9) = -22.5

So, the pairs of numbers and their products are as follows:

(-5)(4.2) = -21 matches with -21.

(-7)(-3) = 21 matches with 21.

(4)(5) = 20 matches with 20.

(2.5)(-9) = -22.5 matches with -22.5.

we know that diameter of the circle is 6 so which gives us the radius which is 3 inch

3.14 otherwise known as pi

lets multiply pi by radius^2

3.14×3^2= 28.26 divide it by 2 because circle is cut in half 28.26/2= 14.13

now let's find area of the rectangle

Rosena bought an 8 pack of donuts to share with her friend at school. The donuts cost $28.00 all together. What is the unit rate for the donuts in $/donuts?

Answers

Answer:

$3.50/donut

Step-by-step explanation:

Since Rosena bought an 8-pack of donuts for $28.00, we can say that the price of $28.00 corresponds with this pack.

The unit rate represents the price per donut, assuming a constant proportion.

The pack that Rosena bought contains 8 donuts. Therefore, to find the price of one donut, divide the price that corresponds with the 8-donut pack by 8, because \(8\div 8=1\).

The price of the 8-pack of donuts was \(\$28.00\). Diving by 8, we have:

\(\frac{\$28.00}{8}=\boxed{\$3.50}\)

Therefore, the unit rate for the donuts is $3.50/donut.

Answer:

$3.5

28/8 = 3.5

Jenny drank 2 3 liter of water Monday before going jogging. She drank 5 7 liter of water after her jog. How much water did Jenny drink altogether?

Answers

you have to add the fractions with a common denominator. 2/3=14/21 and 5/7=15/21. 14/21+15/21=29/21 so she drank 1 8/21 liters

The total amount of water that jenny drank is 27/21

Before jogging she drank 2/3 liters of water

After jogging she drank 5/7 liters of water

The total amount can be calculated as follows

2/3 + 5/7

14+15/21

= 29/21

Hence the total amount of water Jenny drank is 27/21

A pizza shop used 100 pounds of pizza dough to make 155 pizzas. If a large pizza requires 1 pound of pizza dough, and medium pizza requires 1/2 a pound, how many large and medium-sized pizzas were made

Answers

Answer:

45 Large and 55 Medium

Step-by-step explanation:

First, we have to make our 2 equations. One has to have the pizzas and the total pizzas and one has to have the pounds. Suppose large is L and medium is M. L + 1/2M = 100 (pounds) and L + M = 155 (pizzas). Now, we can use elimination to remove one of the variables. But first, we need to multiply the equation (L + 1/2M = 100) by -2 to get (-2L + -M = -200). We can now add the two equations together and get -L = -45. Then we divide this by -1 and get L = 45. The large pizzas and 45 and with some easy subtracting (100 - 45 = 55) we can determine the amount of medium pizzas, which is 55.

Answer:

The answer is C. a = -4,000 m

Step-by-step explanation:

If you subtracted 31,000 from 35,000, you would get 4,000 in a minute. Do the same for the rest, you would also get 4,000 m in a minute, so the answer would be a = -4,000 m

Answer:

A= -4,000m + 39,000

Step-by-step explanation:

If your doing the calculation it would be right

Given: -4,000m + 39,000

-4,000(1) + 39,000 = 35,000ft

-4,000(2) + 39,000 = 31,000ft

I don't know how to explain, but ig if you have the negative 4000, and you mutiply and add 39,000 it would decrease the ft

Use the Midpoint Rule with \(n=5\) to estimate the volume obtained by rotating about the y-axis the region under the curve \(y=\sqrt{1+x^3}\), \(0\leq x\leq 1\).

Answers

To estimate the volume using the Midpoint Rule with \(\displaystyle n=5\), we need to divide the interval \(\displaystyle 0\leq x\leq 1\) into \(\displaystyle n\) subintervals of equal width. Since \(\displaystyle n=5\), each subinterval will have a width of \(\displaystyle \Delta x=\frac{1-0}{5}=\frac{1}{5}\).

Now, let's calculate the volume using the Midpoint Rule. The formula for the volume obtained by rotating about the y-axis is:

\(\displaystyle V\approx 2\pi \sum _{i=1}^{n}y_{i}\Delta x\)

where \(\displaystyle y_{i}\) represents the value of the function \(\displaystyle y=\sqrt{1+x^{3}}\) evaluated at the midpoint of each subinterval.

First, let's find the midpoints of the subintervals. Since the width of each subinterval is \(\displaystyle \Delta x=\frac{1}{5}\), the midpoint of the \(\displaystyle i\)-th subinterval is given by:

\(\displaystyle x_{i}=\frac{\Delta x}{2}+\left( i-\frac{1}{2}\right) \Delta x=\frac{1}{10}+\left( i-\frac{1}{2}\right) \frac{1}{5}\)

Substituting \(\displaystyle x_{i}\) into the function \(\displaystyle y=\sqrt{1+x^{3}}\), we obtain:

\(\displaystyle y_{i}=\sqrt{1+\left( \frac{1}{10}+\left( i-\frac{1}{2}\right) \frac{1}{5}\right) ^{3}}\)

Now, we can calculate the approximate volume using the Midpoint Rule:

\(\displaystyle V\approx 2\pi \sum _{i=1}^{5}y_{i}\Delta x\)

Substituting the values of \(\displaystyle y_{i}\) and \(\displaystyle \Delta x\) into the formula, we can evaluate the sum and compute the estimated volume.
