How can you estimate to find the percent of a number? Please give a full explanation.

1 answer:

6 0

Gee this gonna be hard to do without giving an example, but one way you could estimate the percentage of a number is to round the number to the nearest benchmark number (10 or 5) and estimate the percentage from that new number.
I hope this helped! :-)

h = 93.75 / 12.50

h = 7.5 (or 7 1/2) hrs <====

Given a 30-60-90 triangle with a long<br> leg of 9 in, determine the length of the<br> hypotenuse.

aniked [119]

Answer:

10.38 in

Step-by-step explanation:

Long side would be opposite to 60°.

Since, side opposite to 60° is root 3 upon 2 times of hypotenuse.

$9 = \frac{ \sqrt{3} }{2} \times hypotenuse \\ \\ hypotenuse = \frac{9 \times 2}{ \sqrt{3} } \\ = \frac{18}{ \sqrt{3} } = \frac{18 \sqrt{3} }{3} = 6 \sqrt{3} = 6 \times 1.73 \\ \: \: \: \red{ \bold{hypotenuse = 10.38 \: in}}$
