Darya [45]

Answer: 3 times.

Step-by-step explanation:

Here, The Volume of the gas tank = 4710 $in^3$

While, The radius of the cylindrical shaped bucket = 5 in

And, Height of the cylindrical shaped bucket = 20 in

Therefore, The volume of the bucket = $\pi \times r^2\times h$

= 3.14 × 5 × 5 × 20 = 1570

According to the question, cylinder shaped bucket is used to fill the tank.

Thus, The number of times the bucket will be used to fill the tank

= The Volume of the gas tank/ The volume of the bucket = 4710/1570 = 3

Therefore, The bucket will be used three times to fill the tank.

Negative 3 less than 4.9 times a number, x, is the same as 12.8

A: -3-4.9x=12.8

B: 4.9x-(-3)=12.8

C: 3+4.9x=12.8

D: (4.9-3)x=12.8

E: 12.8=4.9x+3

Answer:

B: 4.9x-(-3)=12.8

C: 3+4.9x=12.8

E: 12.8=4.9x+3

Step-by-step explanation:

The word equation can be expressed mathematically as follows

negative 3 → -3

less than 4.9 times a number , x → 4.9 x - (-3)

is same as 12.8 → 4.9 x - (-3) = 12.8

The equation can be expressed as

4.9 x - (-3) = 12.8

when you open the bracket, you multiply -3 time - 1 . MInus times minus is equals to plus. so you get

4.9 x + 3 = 12.8

12.8 = 4.9x+3
