A bookshop has some fiction and non books. 2/5 of the books are fiction books. Of these, 1/5 are mystery stories. 1/3 of the non fiction books are mystery stories too. What fraction of all the books in the shop are mystery books?
Answer:
1/3 of all of the books
Step-by-step explanation:
5/5 - (2/5 +1/5) =2/5
2/5(1/3) = 2/15 nonfiction mystery books
2/15 + 1/5 = mystery books
1/5 = 3/15
2/15 + 3/15 = 5/15
5/15 = 1/3

It is given that:
Your class earned $55.00 Saturday afternoon by washing cars to raise money for a class trip. This is 1/3 of the money needed for the trip.
Let x be the total amount needed:
A linear equation in one variable can be framed as follows:
1/3 of x = 55
x/3 = 55
x = 55x3
x = $165
Thus, the total amount needed is $165 if your class earned $55.00 Saturday afternoon by washing cars to raise money for a class trip.

A 100-meter sprint is a race using only the straight side of a race track. A 400-meter stick is a race that makes one complete a lap around a racetrack. Why are velocity and speed the same for a 100 m sprint but not a 400 m sprint
Answer
Because velocity and speed differ each other by direction, in a 100 m sprint race the person moves in a straight path without changing its direction where as in a 400 m race. The person moves in a lap around the race track and the direction changes as he turns according to the race track.

Write 5/8 as a percent
A. 0.625
B. 62.5
C. 625%
D. 6.25
Question:- Write ⅝ as a percent
Answer:-
[tex] \frac{5}{8} [/tex]
For making it in percentage we need to multiple the fraction with 100
[tex] \frac{5}{8} \times 100\% \\ \frac{5}{ \cancel{8} {}^{ \: \: \: 2} } \times \cancel{100} {}^{ \: \: \: 25} \\ \frac{5 \times 25}{2} [/tex]
Now we will multiple and divide the above equation with 5 for easy solution. Or you can just divide the equation upto decimal for your answer
[tex] \frac{125}{2} \times \frac{5}{5} \\ \frac{625}{10} \\ 62.5 \: \% \: \: ans[/tex]
So your options (B) 62.5% is correct

The mayor knows the area needed for a flower garden in the park. She wants the base to be a certain length. How can she determine the necessary height to get the correct area of the flower garden? Explain.
Answer:
Answer:The formula for the area of a parallelogram is A = bh, and the formula for area of a triangle is A = 1/2bh. Since a triangle is half of the area of a parallelogram with the same base and height, the only difference in the formula is 1/2.
Step-by-step explanation:
Maria would determine the height by dividing the area of the garden by the base
From the question, she has the area and the base.
Also, the garden has the shape of a parallelogram
The area of a parallelogram is the product of the base and the height.
So, when the area is divided by the base, she gets the height

Q6)
Kerry's workday is 10 hrs. and works 40 hrs. per week, Kerry works for 4 days
Watson's workday is 8 hrs. and works 40 hrs. per week, Watson works for 5 days
Kerry: works 4 days and gets paid $ 12.75 per cat & grooms 15 cats per day, so Kerry makes = 4(12.75 × 15) = 4(191.25) = $ 765
Watson: works 5 days and gets paid $ 12.75 per cat & grooms 10 cats per day, so Watson makes = 5(12.75 × 10) = 5(127.50) = $ 637.50
∴ The difference between their weekly earning is 765 - 637.50 = $ 127.50
