Answer:

Area of new room = 14,616 in².

Step-by-step explanation:

Given : Elly's room measures 78 inches by 96 inches. Sarah's room measures 66 inches by 108 inches.

To find :  They want to combine their rooms. How large will the new room be?

.Solution : We have given that

Length of Elly room = 78 inches.

Width of Elly room =96 inches.

Area of Elly room = Length * width.

Area of Elly room = 78 * 96.

Area of Elly room  = 7488 in².

Length of Sarah room = 78 inches.

Width of Sarah room =96 inches.

Area of Sarah room = Length * width.

Area of Sarah room = 66 * 108.

Area of Sarah room  = 7128 in².

Combine their room = Area of Elly room + Area of Sarah room.

Area of new room = 7488 in² +  7128 in².

Area of new room = 14,616 in².

Therefore, Area of new room = 14,616 in².

Let f(x) = x + 8 and g(x) = x2 − 6x − 7. Find f(g(2)).
just olya [345]
Mathematical Work:
f(x)=x+8
g(x)=x2-6x-7
f(g(2))=(2^2-6(2)-7)+8
f(g(2))=(4-12-7)+8
f(g(2))=-7
Explanation:
f(x)=x+8
g(x)=x2-6x-7
f(g(2))=?
2 was given as the x for function g and when you substitute 2 into function g's equation(g(2)=(2^2-6(2)-7)=-15, you would get -15. The answer to function g would be the x for function f. Which would be f(-15)=-15+8 and the answer for f(g(2)) is -7.

In a clothing store, 65% of the customers buy a shirt, 30% of the customers
diamong [38]

Answer:

75%

Step-by-step explanation:

List out known probabilities

\Pr(shirt) = 0.65 = \frac{65}{100} = \frac{13}{20}\\ \Pr(pants) = 0.40 = \frac{30}{100} = \frac{6}{20}\\\Pr(shirt \cap pants) = 0.20 = \frac{20}{100}=\frac{1}{5}

recall equation

\Pr(A \cup B)=\Pr(A)+\Pr(B)-\Pr(A \cap B)

Plug in values

\Pr(shirt \cup pants)=\frac{13}{20}+\frac{6}{20}-\frac{1}{5}\\\\therefore \Pr(shirt \cup pants) = \frac{15}{20} =\frac{3}{4} = 75\%

X(1+y)=z solve for x
dem82 [27]
<span>X(1+y)=z
Multiply x by 1 and y
x + xy=z
Divide y on both sides
x + x = z/y
Add x to x
2x = z/y
Divide 2 on both sides
Final Answer: x= z/y/2  
Word Form: x equals z divided by y all over two.
