Answer: 31.25%
Step-by-step explanation: To answer the question <em>what percent of 80 is 25</em>, we translate the question into an equation.
So we have "what percent" that's x, "of 80" means times 80, "is 25" = 25.
Now to solve for <em>x</em>, since <em>x</em> is being multiplied by 80, we need to divide by 80 on both sides of the equation. On the left side of the equation the 80's cancel and we have <em>x</em> and on the right side of the equation, we have 25 ÷ 80 which gives us 0<em>.</em>3125. Now, remember that we want to right our answer as a percent so to write 0.3125 as a percent, we move the decimal point 2 places to the right and we get 31.25%.
Therefore, 31.25% of 80 is 25.
Answer:
130 centimeters
Completed question;
Todd placed 32 square tiles along the edge of his wooden dining room table, as shown below.
Todd wants to paint a design on the wood along the diagonal shown. If each tile is 13 centimeters on each side, what is the length of the diagonal shown?
A. 182 centimeters
B. 169 centimeters
C. 130 centimeters
D. 91 centimeters
Step-by-step explanation:
To determine the length of diagonal, we have to first find the length of each side;
According to the attached image;
The length consist of 8 tiles
And breadth consist of 6 tiles
Length per tile = 13 centimeters
Length = 8 × 13 = 104 centimeters
Breadth = 6×13 = 78 centimeters
Using Pythagoras theorem;
diagonal length d = √(104^2 + 78^2)
d = 130 centimeters
