A group of high school students are volunteering for Habitat for Humanity during their summer break. They
are putting the finishing touches on a house they built. Working alone, Kendra can paint a certain room in 7
hours. Joe can paint the same room in 6 hours. Write an equation that can be used to find how long it will
take them working together to paint the room. How many hours will it take them to paint the room? If
necessary, round your answer to the nearest tenth.
In response to the question, we may say that It will take Kendra and Joe expression approximately 3.2 hours to paint the room together.
what is expression ?An expression in mathematics is a collection of representations, numbers, and conglomerates that mimic a statistical correlation or regularity. A real number, a mutable, or a mix of the two can be used as an expression. Mathematical operators include addition, subtraction, fast spread, division, and exponentiation. Expressions are widely used in arithmetic, mathematics, and shape. They are employed in the depiction of mathematical formulas, the solving of equations, and the simplification of mathematical relationships.
Let's denote the time it takes Kendra to paint the room as "K" and the time it takes Joe to paint the room as "J". We can use the formula:
[tex]1/K + 1/J = 1/T\\1/7 + 1/6 = 1/T\\13/42 = 1/T\\13T = 42\\[/tex]
Therefore, T = 42/13 ≈ 3.2 hours (rounded to the nearest tenth).
It will take Kendra and Joe approximately 3.2 hours to paint the room together.

In which expression should the exponents be multiplied
Answer:
when the bases are different and the powers are same
Step-by-step explanation:
(a)²★(a)³=(a)²+³........
Item 3
Solve for a.
a+(−4)=−13
a=−17
a=−9
a = 9
a = 17
Answer:
a = -9
Step-by-step explanation:
a+(-4)=-13
add 4 to each side
a-4+4 = -13+4
a = -9
Answer:
a = - 9
Step-by-step explanation:
a + (-4) = -13
Add 4 to both sides
a + (-4) + 4 = -13 + 4
a + 0 = -9
a = -9

Evaluate the expression (14 − 4)2 ÷ 10.
The value of the expression is value of
Answer:
2
Step-by-step explanation:
PEMDAS says to do the equations in parentheses first
(14-4) = 10
PEMDAS then says to do multiplication or division, whichever comes first in the equation, which is multiplication in this case
(10)2 = 20
20 ÷ 10 = 2
A new car loan has monthly payments of $482.75. How much money will be paid on the car loan after 3 years?
========================================================
Work Shown:
1 year = 12 months
3*(1 year) = 3*(12 months) ..... multiply both sides by 3
3 years = 36 months
You'll make 36 payments, each being $482.75, which means the total amount of money paid is 36*482.75 = 17,379 dollars

Answer:
A
Step-by-step explanation:
You should know the area of a circle, A = πr².
So, all you need to find is the area of half a circle, or A = [tex]\frac{1}{2}[/tex] πr²
We see that the radius is half of the diameter or r = 6 in.
A = [tex]\frac{1}{2}[/tex] (3.14)(6)²
A = 56.52 in²

Answer:
[tex]P(E\ or\ F) = 0.60[/tex]
Step-by-step explanation:
Given
[tex]P(E) = 0.25[/tex]
[tex]P(F) = 0.40[/tex]
[tex]P(E\ and\ F) = 0.05[/tex]

Determine P(E or F)
This is calculated using:
[tex]P(E\ or\ F) = P(E) + P(F) - P(E\ and\ F)[/tex]
[tex]P(E\ or\ F) = 0.25 + 0.40 - 0.05[/tex]

Note: Enter your answer and show all the steps that you use to solve this problem in the space provided. Calculate the area of the trapezoid, which is not drawn to scale.
Answer:
38 in
Step-by-step explanation:
Ok, so the bottom part is a rectangle and the top part is a triangle. We’re gonna split those into two different shapes.
8 * 4 = 32, this is the area of the bottom rectangle.
To get the side length of the top triangle, we have to subtract 8 from 11.
11 - 8 = 3
(3 * 4)/2 = 6, this is the area of the top triangle.
Add the two areas, 32 + 6 = 38
And that’s it, maybe, I think.
A number x decreased by 6 is at most 11.
