The lengths of two sides of a right triangle are 5 inches and 8 inches. What is the difference between the two possible
3241004551 [841]

Answer:

Option 2 - 3.2 inches.                      

Step-by-step explanation:

Given : The lengths of two sides of a right triangle are 5 inches and 8 inches.

To find : What is the difference between the two possible  lengths of the third side of the triangle?

Solution :

According to question, it is a right angle triangle

Applying Pythagoras theorem,

H^2=P^2+B^2

Where, H is the hypotenuse the longer side of the triangle

P is the perpendicular

B is the base

Assume that H=8 inches and B = 5 inches

Substitute the value in the formula,

8^2=P^2+5^2

64=P^2+25

P^2=64-25

P^2=39

P=\sqrt{39}

P=6.24

Assume that P=8 inches and B = 5 inches

Substitute the value in the formula,

H^2=8^2+5^2

H^2=64+25

H^2=89

H=\sqrt{89}

H=9.43

Therefore, The possible length of the third side of the triangle is

L=H-P

L=9.43-6.24

L=3.19

Therefore, The difference between the two possible  lengths of the third side of the triangle is 3.2 inches.

So, Option 2 is correct.

Chad can paint a room in 5 h. cassie can paint the room in 3 h. how long would it take them to paint the room working together?
Georgia [21]
If Chad can paint the whole room in 5 hours, in 1 hour he gets 1/5 of it painted.  If Cassie can paint the whole room in 3 hours, in 1 hour she gets 1/3 of it painted.  If we add those together we can find out how much of the room they can paint together in one hour.  1/5 + 1/3 = 1/x, with x being the number of hours it will take them to paint the room together.  Common denominator is 15, therefore, 3/15 + 5/15 = 1/x and 8/15 = 1/x.  Cross-multiply to get 8x = 15, so it will take them 15/8 hours, or 1.9 hours to paint the whole room together.
