Answer:

C. 240 minutes

Step-by-step explanation:

If 1/3 of a wall takes 20 minutes, then 3/3 of a wall would take 60 minutes(hour). Then multiply 60x4 and you get 240.

20x3=60

60x4=240

Answer:

the area is 50.24 cm^{2}.

Step-by-step explanation:

The formula to find area of a circle is A=πr^{2}. A is area, and r is for radius. Since we have the diameter here, we just need to divide by 2 to find the radius. 8÷2=4, so there, the radius is 4. Now we need to square 4, and do 4x4, which equals 16. Now to multiply 16 by π, or 3.14. 16 x 3.14 = 50.24. The final answer is 50.24 cm^{2}. Hope this helped! :]

2m+(m-15)=90 solve for m
Ronch [10]

Answer:

m = 35

Step-by-step explanation:

2m + m -15 = 90

3m -15 = 90

     +15  +15

3m = 105

/3     /3

m = 35

To check the work just insert 35 for m:

2(35) + 35 -15 = 90

70 + 35 -15 = 90

105 - 15 = 90

90 = 90
