Work Problem: Mrs. Perry needs Mr. Chesah's help painting her new office. Perry could paint her office in 4 hours. She heard that Chesah has the new PAINTMASTER3000...and could paint Perry's fancy new office in half the time. If they work together, how long would it take them to paint Perry's new office?
A 0.75 hrs
B 1.333 hrs
C 6 hrs
D 3 hrs
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.
Explanation: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.

Find the slant height of the pyramid shown.
Answer:
B is the correct answer ( square root of ten)
Step-by-step explanation:
I just did it and got it right
The slant-height of the pyramid having perpendicular height as 3 units, base as 1 unit is : (b) √10.
A Pyramid is a three-dimensional geometric shape with a polygonal base and triangular faces that meet at a single point called the apex. The base can be any polygon, and the number of sides of the base determines the type of pyramid (e.g., a square base yields a square pyramid)
The "Slant-Height" of the given pyramid can be calculated by using Pythagoras-Theorem, which states that; (slant-height)² = (perpendicular)² + (base)²;
Substituting Perpendicular height as 3 units, base as 1 unit, and slant-height as "x";
We get,
⇒ 3² + 1² = x²,
⇒ x² = 9 + 1,
⇒ x² = 10,
⇒ x = √10,
Therefore, the slant-height is √10, option (b) is correct.

⇒ 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

Finding the area in this composite figure
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.
Explanation: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.

Which is the most efficient way to solve this equation?
x−57=135
A. Do nothing because the equation is already solved.
B. Subtract 135 from both sides of the equation so all terms will be on the same side of the equal sign.
C. Subtract 57 from 135 because x equals 78.
D. Add 57 to both sides of the equation because addition is the inverse operation of subtraction.
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.

5 x minus 2 y = 10. y = one-fourth x + 1.
y = five-halves x minus 5
y = five-halves x + 10
y = negative five-halves x + 10
y = negative 5 x minus 5

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

Triangles A B C and T P Q are shown. Sides A C and T Q are congruent. Angles B C A and P Q T are congruent. Which statements are true about additional information for proving that the triangles are congruent? Select two options. If AngleA ≅ AngleT, then the triangles would be congruent by ASA. If AngleB ≅ AngleP, then the triangles would be congruent by AAS. If all the angles are acute, then the triangles would be congruent. If AngleC and AngleQ are right angles, then triangles would be congruent. If BC ≅ PQ, then the triangles would be congruent by ASA.
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.
Congruent triangles: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.

The pyramids have always fascinated Kristina, so she wants to build two model pyramids to put on her mantel. She wants her model of Khufu’s pyramid to have a volume of 73.5 cubic inches and a height of 4.5 inches. What would the side length of the base of the pyramid be? Is this number rational or irrational? Why?
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:
7 rational a rational number is a whole number

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).
What are the properties of logarithms?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

Answer:
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.
