Answer:

10 ft

Step-by-step explanation:

Area of a rectangular room is

A = l*w

We know the area and the length

90 = 9*w

Divide by 9

90/9 = 9w/9

10 =w

The width is 10 feet

miguel joins a gym that has a 40$ membership fee and charges 22.50 per month.he also joins a martial art class that charges 16$
Kipish [7]

Answer:

A

Step-by-step explanation:

The gym membership is going to cost 40 initially plus 22.50 for each month after.

The total cost for the gym can be expressed as 40+22.50m

The martial arts class is going to cost 26 initially plus 16 for each month after.

The total cost for the martial arts class can be expressed as 26+16m

Now we have to combine these to get the total cost for both the gym and the martial arts class:

(40+22.50m) + (26+16m) = 66 + 38.50m  (option A)

I need help with this math problem

Consider the right triangle HBF. The Pythagorean theorem tells you ...
   HF² = HB² + BF²

The lengths HB and BF can be determined by counting grid squares, or by subtracting coordinates. Here, it is fairly convenient to count grid squares. When we do that, we find ...
   HB = 2
   BF = 5
Using these values in the equation above, we get
   HF² = 2² + 5²
   HF² = 4 + 25 = 29
Taking the square root gives the length HF.
   HF = √29
