Line AC=21cm
line AB=20cm

substitute values into the pythagorean theorem to find the hypotenuse
(a^2 + b^2 = c^2):

(21)^2 + (20)^2 = c^2
441 + 400 = c^2
841 = c^2
29=c

so, line BC = 29cm

hope this was helpful :)

Answer:

$Total\ Selection = 30\ ways$

Step-by-step explanation:

Given

Girls = 3

Boys = 5

Required

How many ways can 2 boys and girls be chosen?

The keyword in the question is chosen;

This implies combination and will be calculated as thus;

$Selection =\ ^nC_r = \frac{n!}{(n-r)!r!}$

For Boys;

n = 5 and r = 2

$Selection =\ ^5C_2$

$Selection = \frac{5!}{(5-2)!2!}$

$Selection = \frac{5!}{3!2!}$

$Selection = \frac{5 * 4 * 3!}{3!*2 * 1}$

$Selection = \frac{20}{2}$

$Selection = 10$

For Girls;

n = 3 and r = 2

$Selection =\ ^3C_2$

$Selection = \frac{3!}{(3-2)!2!}$

$Selection = \frac{3!}{1!2!}$

$Selection = \frac{3 * 2!}{1 *2!}$

$Selection = \frac{3}{1}$

$Selection = 3$

Total Selection is calculated as thus;

$Total\ Selection = Boys\ Selection * Girls\ Selection$

$Total\ Selection = 10 * 3$

$Total\ Selection = 30\ ways$

The police uses a speed gun to monitor one part of the highway. During one hour, 6 out of 25 cars were traveling above the speed

Oksanka [162]

24% of the cars were travelling above the speed limit.

Step-by-step explanation:

Given,

Total cars monitored = 25

Cars traveling above the speed limit = 6

Percent of cars traveling above speed limit = $\frac{Cars\ travelling\ above\ speed\ limit}{Total\ cars\ monitored}*100$

Percent of cars = $\frac{6}{25}*100\\$

$Percent\ of\ cars=\frac{600}{25}\\Percent\ of\ cars=24\%$

24% of the cars were travelling above the speed limit.
