What is the hypotenuse of a right triangle if the legs are each 20 inches long? Round to the nearest whole number. A. 28 B. 29 C

marusya05 [52]

Answer:

The answer is A.

Step-by-step explanation:

You have to apply Pythagoras Theorem :

${c}^{2} = {a}^{2} + {b}^{2}$

$let \: a = 20,b = 20$

${c}^{2} = {20}^{2} + {20}^{2}$

${c}^{2} = 800$

$c = \sqrt{800}$

$c = 28 \: (nearest \: whole \: no.)$

P.S (Take note):

Pythagoras Theorem can only applied in right angle triangle.

Al terminar una obra tres albañiles cobran $16800 y se dividen el dinero a razón 5:7:9. Calcular cuánto dinero le corresponde a

NNADVOKAT [17]

Answer:

$4000, $5600 and $7200

Step-by-step explanation:

Let the money be 5x,7x and 9x.

Total collection of money is $16,800

ATQ,

5x+7x+9x=$16,800

21x=$16,800

$x=\dfrac{16800}{21}\\\\x=\$800$

So, the values are :

5x=5(800) = $4000

7x=7(800) = $5600

9x=9(800) = $7200

A fair number cube is rolled. What is the probability that a number less than 4 is rolled?

patriot [66]

Answer: B) 1/2

There are six sides labeled 1,2,3,4,5,6. We want values that are less than 4, so we want values from the set {1,2,3} which represents half of the list. In other words, we have 3 ways of getting what we want (1 or 2 or 3) out of 6 ways total (1,2,3,4,5,6) to have 3/6 = 1/2
