Answer: 7

Step-by-step explanation:

Since we are given the information that a group of friends had 28 driveways to shovel and that one of them shoveled 1/4 of the driveways.

The number of driveways that he shovel will be:

= 1/4 × 28

= 7

Therefore, he shovel 7 driveways.

Answer:

The quotient = 4x - 17 and the remainder = 54

Step-by-step explanation:

$\frac{4x^{2}-5x+3 }{x+3}=4x+\frac{-17x+3}{x+3}$

$\frac{-17x+3}{x+3}=-17+\frac{54}{x+3}$

The quotient = 4x - 17 and the remainder = 54

Question 2 of 15. Step 1 of 1

Answer:

A = -68.75p +2906.25

Step-by-step explanation:

We can solve for m and b using the given values of A and p.

1600 = m·19 +b

2150 = m·11 +b

Subtracting the second equation from the first, we have ...

-550 = 8m

m = -550/8 = -68.75

Substituting this into the first equation gives ...

1600 = 19·(-68.75) +b

b = 1600 +1306.25 = 2906.25

The desired linear equation is ...

A = -68.75p +2906.25

Answer:

The volume of the solid is $1,021m^3$

Step-by-step explanation:

1. Cylinder

For find the volume of a cylinder we use the next formula:

$V_{cylinder} = \pi h r^2 = \pi \cdot 9m\cdot (5m)^2 \approx 706.86m^3$

Then the volume of the cylinder is equal to $706.86m^3$

2. Cones

For find the volume of a cone we use the next formula:

$V_{cone} = \pi \frac{h}{3} r^2 = \pi \cdot \frac{6m}{3} \cdot (5m)^2 \approx 157.08m^3$

However there are two cones so we have to multiply the volume of one cone for two and we get the total volume for the cones which is $314.16m^3$

3. Sum of the volumes

Finally we sum the volumes of the cylinder and the cones for get the final result

$V_{cylinder} + V_{cones} = 706.86m^3 + 314.16m^3 \approx 1021m^3$

So approximating the result is $1021m^3$
