A customer wants to put in a concrete driveway that is 10" thick. How much concrete would it take to pour a driveway that measur

stellarik [79]

Answer: 22.59 yd^3

Step-by-step explanation:

First the volume of a cuboid whose measurements are:

L = length, W = width and T = thiknes is:

V = L*W*T.

We want to calculate the volume of a shape that is:

10'' thick, 18' wide and 42' long.

This notation is:

(') = feet

('') = inches

The first step is to write our 3 numbers in the same units, then we can use that:

1 inch = 0.083 ft.

Then 10 inches are equal to:

10'' = 10*(0.083 ft) = 0.83 ft = 0.83'

Then the volume of concrete needed will be:

V = 0.83ft*18ft*42ft = 627.48 ft^3

But we want this expressed in yd^3

1ft = 0.33 yd

then

1ft^3 = (0.33 yd)^3 = 0.036 yd^3

then 627.48 ft^3 can be written as:

627.48 ft^3 = 627.48*( 0.036 yd^3) = 22.59 yd^3

The length of tile B is about 3.87298 inches. Which mark on the tape measure is closest to 3.87298 inches? The tape measure is m

vladimir1956 [14]

Answer:

$\frac{62}{16}$

Step-by-step explanation:

We are given that,

Length of the tile = 3.87298 inches.

The markings on the tape are marked in $\frac{1}{16}$ inches.

As, we see that,

$\frac{64}{16}$ = 4 inches.

So, the required mark will be before than $\frac{64}{16}$ mark.

Since, $\frac{62}{16}$ = 3.875

Hence, the mark closest to 3.87298 inches is $\frac{62}{16}$ .

If f(x)= 3x^2 + 3x^1/2 +3x what is the value of f(-9)

Dahasolnce [82]

Answer:

216 + 9i

Step-by-step explanation:

Given: f(x) = 3x² + 3 $x^{1/2}$ + 3x

When x = -9, f(x) equals to;

3(-9)² + 3(-9 $)^{1/2}$ + 3(-9)

243 + 3(3i) - 27

243 + 9i - 27

216 + 9i
