Let "x" equal the number of books that Jill started with. Solve for "x" :
____________________________________________
x – (1/2)x + 16 = 36 ;
1x – (1/2)) = (1/2)x ;
(1/2)x + 16 = 36 ;
Subtract "16" from EACH SIDE of the equation:
(1/2)x + 16 – 16 = 36 – 16 ;
(1/2)x = 20 ;
Multiply each side of the equation by "2" ;
2*(1/2)x = 20 * 2 ;
to get: x = 40 .
____________________________________________
The answer is: " 40 books " .

I would be much appreciated if somebody took time out of their day to answer this for me.

You have to assume something or it is unsolvable.
We will assume that the triangle is divided into 2 smaller right triangles. They will be subject to a^2 + b^2 = c^2
a = 32/2 = 16
b = h
c = 20
20^2 = 16^2 + h^2
400 = 256 + h^2 Subtract 256
400 - 256 = h^2
144 = h^2
h = sqrt(144)
h = 12
Now we can find the area.
h = 12
base = b = 32
Area = 1/2 * b * h
Area = 1/2 * 32 * 12
Area = 192 square inches.
Problem 5
Same assumption. Same method.
a^2 + b^2 = c^2
c = 25
b = 7
h = ???
h^2 + 7^2 = 25^2
h^2 + 49 = 625
h^2 = 625 - 49
h^2 = 576
h = sqrt(576)
h = 24
Area = 1/2 Base * h
base = 2*7
base = b = 14
Area = 1/2 * 14 * 24
Area = 168 <<<< answer.

also 0.7 as a repeating decimal to a fraction
show your work
Answers
The decimal 0.5 converts to the fraction 1/2 and the decimal 0.7 converts to the fraction 7/10.
Explanation:To convert the decimal 0.5 and 0.7 into fractions, we use the definition of a decimal. A decimal is a representation of a fraction in terms where we have a power of 10 in the denominator. For instance:
To convert 0.5 into a fraction, we can think of it as 0.5/1 which equals to 5/10 or simplifies to 1/2. Converting 0.7 into a fraction, would give us 0.7/1 which is equal to 7/10.
So, 0.5 as a decimal is 1/2 as a fraction and 0.7 as a decimal is 7/10 as a fraction.

You plan to paint the outside of this garage, including the roof. Which calculation will help you best decide how much paint you will need? (Omit the floor of the garage in your calculation.) Add the areas of 9 rectangles and 2 triangles. Add the areas of 6 rectangles and 2 triangles. Add the volumes of 1 rectangular prism and 1 triangular prism. Add the perimeters of 4 rectangles and 2 triangles.
Answers
The roof will be two rectangles.
The ends holding up the roof will be two triangles.
The 2nd selection is appropriate (areas of 6 rectangles + 2 triangles).
_____
Yes, you're trying to find the volume of paint, but paint is sold in terms of the number of square feet (area) it covers. Rarely do we concern ourselves with computing paint volume from the thickness of the film covering the area. Certainly, the volume of paint is substantially less than the volume of the walls or the entire garage.
Answer:
add the areas of 6 rectangles and 2 triangles

What are the ratio and proportion?The ratio is the division of the two numbers.
For example, a/b, where a will be the numerator and b, will be the denominator.
Proportion is the relation of a variable with another. It could be direct or inverse.
The ratio is the division and the ratio can be bigger than the amount which is put on the ratio or the ratio could be smaller than the amount which is put on the ratio. It depends upon whether the numerator is big or small than the denomintor.
Given the condition in the question let's suppose the number is x then
seven-time is 7x and 5 means 7x + 5.
Similarly -2 times means -2x and 11 means -2x + 11 hence (7x +5 )/(-2x+11) will be correct answer.

Answers
The question says :Mrs Henley built a cage for her bird .
The bottom of the cage Mrs Henley build has to be covered by a newspaper.
To cover the bottom by newspaper we need to find the area of bottom.
The formula to find the area of bottom is length x width.
The dimensions of the bottom is given as [tex] \frac{1}{4} and \frac{1}{2} yard. [/tex]
Area of bottom = [tex] \frac{1}{4} times \frac{1}{2} = \frac{1}{8} [/tex]
Answer: The area that needs to be covered is [tex] \frac{1}{8} [/tex] square yards.

Answer: [tex]\dfrac{1}{10}[/tex]
Step-by-step explanation:
Given : Number of yellow Skirt Number =5
Total skirt = [tex]5+8+4+3=20[/tex]
The probability that she will select a yellow skirt will be :_
[tex]\dfrac{5}{20}=\dfrac{1}{5}[/tex]
Total faces in coin=2
Number of tails = 1
The probability that the coin will land tails up :-
[tex]\dfrac{1}{2}[/tex]
Since ,both events are independent , then the probability that she will select a yellow skirt and that the coin will land tails up is given by :-
[tex]\dfrac{1}{5}\dfrac{1}{2}=\dfrac{1}{10}[/tex]
Can the sides of a triangle have lengths 6.2, 0.5, and 7.8?
yes or no
Answers
According to the triangle inequality theorem, the sum of any two sides of the triangle has to be bigger than the last side. Let's test this.
[tex]6.2+7.8\ \textgreater \ 0.5[/tex]
This inequality satisfies the triangle inequality theorem.
[tex]7.8+0.5\ \textgreater \ 6.2[/tex]
This also satisfies the theorem.
[tex]6.2+0.5 \textless \ 7.8[/tex]
Uh oh. This does not satisfy the triangle inequality theorem. Thus, it is not possible for a triangle to have these side lengths.

It took Yuik (1/6) of a hour to water get flowers and (4/6) of an hour to weed her garden. What fraction of an hour did Yuik work in her yard
Answers
The required fraction of an hour is 5/6 Yuik work in her yard.
What is the fraction?A fraction is defined as a numerical representation of a part of a whole that represents a rational number.
It took Yuik (1/6) of an hour to water the flowers and (4/6) of an hour to weed her garden, so in total, she worked for (1/6) + (4/6) = 5/6 of an hour in her yard.
To add the two fractions, we need to have a common denominator, which is 6. Then we can add the numerators (1 + 4) to get 5.
⇒ 5/6
Thus, the final fraction is 5/6.
