The length of a rectangle is 8 1/2 inches and the width is 3 1/4 inches. What is the ratio, using whole numbers, of the length t

frosja888 [35]

Short answer 34/13
Start by converting both to improper fractions.

8 1/2 = (2*8 + 1)/2 = 17/2

3 1/4 = (3*4 + 1)/4 = 13/4

Next set up a 4 layer fraction

$\dfrac{\dfrac{17}{2}}{\dfrac{13}{4} }$

Invert the lower fraction and multiply $\dfrac{17}{2}* \dfrac{4}{13}$

Cancel the 2 and the 4 leaving you with a 2 in the numerator. $\dfrac{17*2}{13} =\dfrac{34}{13}$

Use the distance formula to find the distance, to the nearest tenth, from S(7, −1) to V(−1, 3).

Answer: 8.9 units (choice C)

Explanation:

We plug $(x_1,y_1) = (7,-1) \text{ and } (x_2,y_2) = (-1,3)\\\\$ into the distance formula to get the following

$d = \sqrt{(x_1 - x_2)^2 + (y_1 - y_2)^2}\\\\d = \sqrt{(7-(-1))^2 + (-1-3)^2}\\\\d = \sqrt{(7+1)^2 + (-1-3)^2}\\\\d = \sqrt{(8)^2 + (-4)^2}\\\\d = \sqrt{64 + 16}\\\\d = \sqrt{80}\\\\d \approx 8.94427\\\\d \approx 8.9\\\\$
