√81 - √25 = 9 - 5 = 4

√64 + √25 = 8 + 5 = 13

√64 - 31 = 8 - 31 = -23

Answer:

1 3/4

Step-by-step explanation:

So 2 1/4= 9/4. 1 1/4=5/4. So 9/4+5/4=14/4, which is 3 2/4. 5 - 3 1/4= 1 3/4. And I think the grammar in this question is wrong. The last sentence says how much will he have left after making BOTH cakes. Im pretty sure its one big delicious cake.

\(P = I\cdot V \text{, where P is power in Watts, I is current and V is in Volts.}\), but

\(V = R\cdot I \text{, where V is in Volts, R is resistance and I is current.}\)

Doing the math:

\(P = I\cdot V\)

\(P = I\cdot R\cdot I\)

\(P = R\cdot I^2\)

\(P = 300^2\cdot 0.3\)

\(P = 27000\)

She had $640.8 at first

Step-by-step explanation:

1/4x+1/6x=267

3/12x+2/12x = 267

5/12x = 267

x = 267 x 12/5

x = 3204/5

x = 640.8

Answer:

That would be a 30.9 or 31% increase!

Step-by-step explanation:

Formula: % increase = Increase ÷ Original Number × 100

To find the increase subtract the new increase number by the original.

72-55 = 17

Increase: 17

Original: 55

Here's the equation when using the formula:

17/55*100

That would get you the answer of 30.909091

Answer:

Step-by-step explanation:

There can be many ways to solve this problem. I solved the problem by subtracting the fractions, then dividing the fractions to get the increase in percentage.

Hence, the increase in percentage is about 31%.

Given, Two vertical poles of length 6 feet and 8 feet, respectively, stand 10 feet apart.

A cable reaches from the top of one pole to some point on the ground between the poles and then to the top of the other pole. We need to express the amount of cable used, f, as a function of the distance from the 6-foot pole to the point where the cable touches the ground, x.

The probability that exactly four people get the right letter is 1/120.

Let the people form a line and the envelopes are on the table.

The first person has a 1 in 5 chance of selecting the right letter.  (He selects the correct one)

Now there are 4 on the table so the second person has a 1 in 4 chance of getting the right one (He selects the correct one)

Now there are 3 on the table so the second person has a 1 in 3 chance of getting the right one (He selects the correct one)

Now there are 2 on the table so the second person has a 1 in 2 chance of getting the right one (He selects the correct one)

and so on

so

P(everyone getting the correct letter) = 1/5*1/4*1/3*1/2*1/1=1/5!=1/120.

Answer:

hello

g (x)= x² - 5

g (3) = 3² - 5 =  9 - 5 =  4

Step-by-step explanation:

Mr. Schwartz will need to order more wheels after building 12 cars.

The number of cars x Mr. Schwartz builds before he places an order for more wheels can use the following steps:

Determine how many wheels are used per car:

4 wheels/car

Determine the number of wheels available at the start of the week:

85 wheels

Determine the minimum number of wheels needed to be available before placing an order:

40 wheels

Set up an inequality to represent the situation using x to represent the number of cars built before an order is placed:

Number of wheels used = 4x

Number of wheels remaining = 85 - 4x

Order is placed when number of wheels remaining is less than 40:

85 - 4x < 40

Solve for x by isolating the variable:

85 - 4x < 40

-4x < -45

x > 11.25

Since x represents the number of cars built can't have a fractional value for x.

The nearest integer to get the minimum number of cars that need to be built before an order is placed:

x > 12

The final amount after 9 years on a sum of $800 at 6% per annum compounded monthly is $1370.

The "Compound-Interest" refers to the interest earned on both the principal amount and the accumulated interest from previous periods, resulting in exponential growth over time.

To calculate the compound interest earned for a principal amount "P", an annual interest rate "r", and a time period of "t" years compounded n times per year, we use the following formula: \(A = P(1 + \frac{r}{n} )^{nt}\),

where A is "final-amount" after "t" years,

In this case, the principal amount "P" is $800,

The "annual-interest-rate" (r) is = 6%, and the time period "t" is 9 years.

The interest is compounded monthly, which means n = 12 (12 months in a year).

Substituting the values,

We get,

⇒ A = 800(1 + 0.06/12)¹²ˣ⁹,

⇒ A = 800(1 + 0.005)¹⁰⁸,

⇒ A = 800 × (1.005)¹⁰⁸,

⇒ A ≈ 1370,

Therefore, the total amount after 9 years is approximately $1370.

Solution;

y=5x

Explanation;

The given equation, y = x + 3, is not a logarithmic function. A logarithmic function is a type of function where the variable appears as the exponent of a fixed base.

To determine if a function is logarithmic, we need to check if the variable is the exponent. In the given equation, the variable x appears as an additive term with a constant value of 3. It is not the exponent of any base. Therefore, y = x + 3 is not a logarithmic function.

An example of a logarithmic function is y = log(base 2)(x), where the variable x appears as the exponent with a fixed base of 2. In this function, the logarithm helps us find the power to which 2 must be raised to obtain x.

Answer:

672 had dark hair, 592 had blond hair, and 48 had red hair

Step-by-step explanation:

To solve this problem, we need to first find the total number of people for each hair color based on the given ratio.

Let's start by finding the common factor that we can use to scale the ratio up to the total number of people, which is 1,312:

42 + 37 + 3 = 82

We can then divide 1,312 by 82 to get the scaling factor:

1,312 ÷ 82 = 16

This means that for every 16 people, there are 42 with dark hair, 37 with blond hair, and 3 with red hair.

To find the actual number of people with each hair color in the town meeting, we can multiply the scaling factor by the number of people for each hair color in the ratio:

Dark-haired people: 42 × 16 = 672

Blond-haired people: 37 × 16 = 592

Red-haired people: 3 × 16 = 48

Therefore, there are 672 people with dark hair, 592 people with blond hair, and 48 people with red hair at the town meeting.

Step-by-step explanation:

The length of BC is 15 units.

Right angled triangle are those triangle for which one of the angle is 90 degrees.

Given a right angled triangle ABC.

Given that angle C is right angle.

Side AB is the hypotenuse, AC is the base and BC is the altitude.

Pythagoras theorem states that for a right angled triangle, the square of the hypotenuse is the sum of the squares of base and altitude.

Using the theorem,

(AB)² = (AC)² + (BC)²

(BC)² = (AB)² - (AC)²

        = 17² - 8²

        = 289 - 64

        = 225

BC = √225 = 15 units

Hence the side length of BC is 15 units.

The sample is a stratified sample.

A stratified sample is a sampling method in which a population is separated into distinct, non-overlapping subpopulations, or strata, and a random sample is taken from each stratum.

This is frequently utilized when the population contains subpopulations with distinct characteristics, and the researcher wants to guarantee that these subpopulations are adequately represented in the sample.

Likewise, in the provided scenario of the electronics store, the store will first separate the customers who purchased a computer over the past two years and then take 100 receipts through a random number generator to question customers about high-speed Internet rates.

This way, it can ensure that all customers are adequately represented in the sample and the information it receives is not biased.

A stratified sample is a sampling technique used in statistics and research to ensure that the sample accurately represents the different subgroups or strata within a population. It involves dividing the population into distinct subgroups or strata based on certain characteristics or variables and then selecting a sample from each stratum.
