Answer:

Side length = 7 inches

This number is a rational number, because it is a whole number and it can be represented as a fraction (7 = 14/2 for example)

Step-by-step explanation:

The volume of the pyramid can be calculated as:

V = (1/3)*A*h

Where V is the volume, A is the area of the base and h is the height.

If the volume is 73.5 in3 and the height is 4.5 in, we can find the area of the base:

73.5 = (1/3)*A*4.5

A = 73.5*3/4.5 = 49 in2

As the pyramid have a square base, we can calculate the side length of the base:

A = L*L (L = length)

49 = L^2

L = 7 inches

This number is a rational number, because it is a whole number and it can be represented as a fraction (7 = 14/2 for example)

Answer:

y= 5/2x - 5

Step-by-step explanation:

5x   -   2y   =   10

-5x                  -5x (Subtract both sides by 5x to leave y by itself)

-2y = -5x + 10

-2y/-2 = -5/-2 + 10/-2

(Divide both sides by -2 to leave y with no coefficient. -5/-2 = 5/2 because there are two negatives. 10/-2 = -5.

y = 5/2 - 5

Definition of Isosceles triangle --- two side lengths are always equal!

Answer: 15

Step-by-step explanation: By looking at the shape, you can tell it's the exact same size.

To solve for the area of a composite figure, break it down into simpler shapes and calculate their areas, ensuring all measurements are in the same units and converting if necessary, then add the areas together and express the answer to the correct number of significant figures.

The question is about finding the area of a composite figure, which is often a problem in high school mathematics. When calculating the area of a composite figure, we can break it down into simpler shapes such as rectangles and triangles. The area of a rectangle is found by multiplying its height by its width, while the area of a triangle is half the product of its base and height. We can then add these areas together to get the total area of the composite figure. It's important to ensure that all measurements are in the same units before performing the calculation. If necessary, we use conversion factors to change to the appropriate units and report the final answer to the correct number of significant figures.

For example, if we are given a rectangle with dimensions provided in meters and centimeters, we convert all measurements to the same unit, usually the meter, before calculating the area. To maintain accuracy, we use the fact that the number 1 and 100 in the conversion factors (such as 1m = 100 cm) are exact numbers and do not impact the significant figures of our final answer.

The side lengths ( 8, 15, 17 ) and ( 15, 20, 25 ) form a right-angle triangle.

A right triangle or right-angled triangle, or more formally an orthogonal triangle, formerly called a rectangle triangle, is a triangle in which one angle is a right angle or two sides are perpendicular.

According to the given problem,

We know, in a right-triangle,

Hypotenuse² = Perpendicular² + Base²

For sides, 8, 15, 17

⇒ Hypotenuse ² = 8² + 15²

⇒ Hypotenuse² = 64 + 225

⇒ Hypotenuse = √289

⇒ Hypotenuse = 17

For sides, 15, 20, 25,

⇒ Hypotenuse² = 15² + 20²

⇒ Hypotenuse² = 225 + 400

⇒ Hypotenuse = √625

⇒ Hypotenuse = 25

Hence, we cam conclude, the sides, ( 8, 15, 17 ) and ( 15, 20, 25 ) form a right-triangle.

Answer:

You have to factor the equation and the way you do this is to find two numbers that multiply to get -15 and add to get -2 and those numbers are 3 and -5 so the factors are (x+3) and (x-5)

You set them equal to 0 and solve for x

x+3=0           x=-3

x-5=0            x=5

SO THERE YOU HAVE IT: x=5!

Answer: The Answer is D.

Step-by-step explanation: You are trying to get x by itself, and in order to do that, you need to get the 57 away from it. In order to do THAT, you need to do the opposite of what s already being done. Since your already subtracting it, in order to get it away from x, you need to add it to itself, and then add it to the other side, because what you do to one side, you do to one side, you must do to the other.

Answer:

If Angle A ≅ Angle T, then the triangles would be congruent by ASA

If Angle B ≅ Angle P, then the triangles would be congruent by AAS.

Step-by-step explanation:

It's already given that side AC and side TQ are congruent, and angle BCA and angle PQT are congruent too. So if angle A and angle T were congruent, this would be the ASA Theorem. And if angle B were to be congruent to angle P, this would be the AAS Theorem.

Since you only need to pick 2 answer choices, you can stop there.

If Angle A ≅ Angle T, then the triangles would be congruent by ASA

If Angle B ≅ Angle P, then the triangles would be congruent by AAS.

Since

Sides A C and T Q are congruent. Angles B C A and P Q T are congruent.

So here we can say that side AC and side TQ are congruent, and angle BCA and angle PQT are congruent too. So in the case when angle A and angle T were congruent, this would be the ASA Theorem. And if angle B were to be congruent to angle P, this would be the AAS Theorem.

Answer:

6 hrs

Step-by-step explanation: If Im reading corectly your saying that Mrs. Perry is painting for 4 hours plus Mr. Chesah painting for 2 hours (half of 4 hours) Add them up and get 6 hrs.  I hope this is what you meant.

To find out how long it would take Mrs. Perry and Mr. Chesah to paint the office together, we can use the idea of work completion rate. When two people work together, their work completion rates are added. Therefore, if they work together, it would take them 1 hour and 20 minutes to paint the office.

To find out how long it would take Mrs. Perry and Mr. Chesah to paint the office together, we can use the idea of work completion rate. Let's say that Mrs. Perry can paint 1 office in 4 hours, which means her work completion rate is 1/4 offices per hour. Since Mr. Chesah can paint the same office in half the time, his work completion rate is 1/2 offices per hour.

When two people work together, their work completion rates are added. So, the combined work completion rate of Mrs. Perry and Mr. Chesah is 1/4 + 1/2 = 3/4 offices per hour.

To determine how long it would take them together to paint Perry's office, we can take the reciprocal of the combined work completion rate. This gives us 4/3 hours, which is equivalent to 1 hour and 20 minutes. Therefore, if they work together, it would take them 1 hour and 20 minutes to paint the office.

Answer:

233 in^3

Step-by-step explanation:

First we will find the volume of the square at the bottom

V = s^3  where s is the side length

V = 5^3

V = 125 in^3

Then we will find the volume of the rectangular prism at the top

V = l*w*h

V = 12*3*3

V =108 in^3

The total volume is the sum of the two volumes

V = 125+108

    = 233 in^3

Null Hypothesis, [tex]H_0[/tex] : P = 4.1%

Alternate Hypothesis, [tex]H_A[/tex] : P > 4.1%

Step-by-step explanation:

We are given that a psychologist claims that more than 4.1% of the population suffers from professional problems due to extreme shyness.

Let p = true percentage  of the population that suffers from extreme shyness.

So, Null Hypothesis, [tex]H_0[/tex] : P = 4.1%

Alternate Hypothesis, [tex]H_A[/tex] : P > 4.1%

Here, null hypothesis states that % of the population who suffers from professional problems due to extreme shyness is equal to 4.1%.

On the other hand, alternate hypothesis states that more than 4.1% of the population suffers from professional problems due to extreme shyness.

So, the above hypothesis would be appropriate for conducting the test.

Answer:

option A

Step-by-step explanation:

log_2(100)

we can simplify it

we can use base change formula

log_2 (100)=\frac{ln\left(100\right)}{ln\left(2\right)}

log_2 (100)=6.643856

Second value is :

log_6(20)

we can simplify it

we can use base change formula

log_6(20)=\frac{ln\left(20\right)}{ln\left(6\right)}

log_6(20)=1.67195

so, we know that

6.6438 is almost 4 times of 1.67195

The value of log₂ (100) is about 4 times the value of log₆(20). The correct answer would be an option (A).

There are four basic properties of logarithms:

logₐ(xy) = logₐx + logₐy.

logₐ(x/y) = logₐx - logₐy.

logₐ(xⁿ) = n logₐx.

logₐx = logₓa / logₓb.

According to the problem, we will use some of the basic logarithmic properties,

The logarithms expression is given, as follows:

log₂(100)

It can use the base change formula,

log₂ (100) = ln (100) / ln (2)

log₂ (100) = 6.643856

The second value is :

log₆(20)

It can use the base change formula

log₆(20) = ln (20) / ln (6)

log₆(20) = 1.67195

Since 6.6438 is almost 4 times 1.67195

Hence, the correct answer would be option (A).
