Wilma can mow a lawn in 120 minutes. Rocky can mow the same lawn in 80 minutes. How long does it take for both Wilma and Rocky t
saw5 [17]
Work in the rates  / minute 
wilma:-  in 120 minutes she mows 1 lawn
             so in 1 minute she mows 1/120 lawn

similarly, Rock mows 1/80 lawn in 1 minute

working together  1/120 + 1/80  = 1/x  where x is number of minutes working together

1/20 + 1/80 =  1/48  

so 1/x = 1/48

x = 48

answer is 48 minutes

one leg of a right triangle is 6.4 cm long the length of the second leg is 3.5 cm what is the length of the hypotenuse rounded t
Valentin [98]

Answer:

7.3

Step-by-step explanation:

In order to find the hypotenuse, we just need to use the Pythagorean Theorem.

Remember, that this theorem only works for right triangles.

This theorem states that a^2+b^2=c^2

This is where a and b are legs of the triange, and c is the hypotenuse.

Knowing this, we can plug our values in.

6.4^2+3.5^2=c^2

Simplify.

41.344+12.25=c^2

53.594=c^2

Root both sides.

c=7.32 (about)

Round that to tenths.

c=7.3
