It would be 40 miles per hour. That is because if 20 miles is what he can cover in a half hour, than in one full hour he would go twice the amount of time. So 20 times 2 is fourty. So 40 miles per hour is the answer.

likoan [24]

Answer:

72.4 seconds

Step-by-step explanation:

We are given that,

Time taken by each person in the team = 18.1 seconds

Number of members in the team = 4

It is required to find the total time taken by the team to finish the race.

Thus, the time taken taken = 4 × 18.1 = 72.4 seconds

Hence. the team finished the race in 72.4 seconds.

For the right Triangle below, Find the exact values of the side lengths c and a.

vladimir2022 [97]

$c=3\sqrt{3}\\a=4\sqrt{2}$

Step-by-step explanation:

The trigonometric ratios will be used used for finding the values of given variable

For c

We have to use a ratio that has perpendicular and base in it. so we will use tan x

$tan\ 60 = \frac{P}{B}\\tan\ 60=\frac{c}{3}\\\sqrt{3}=\frac{c}{3}\\3*\sqrt{3}=c\\c=3\sqrt{3}$

similarly for a

$sin\ 45 = \frac{b}{h}\\\frac{\sqrt{2}}{2}=\frac{a}{8}\\\frac{\sqrt{2}}{2}*8=a\\a=4\sqrt{2}$

Hence,

$c=3\sqrt{3}\\a=4\sqrt{2}$
