4x + 10 = -26

4x + 10 - 10 = -26 - 10

4x =-36

4x / 4 = -36 / 4

x = -9

The input is -9.

1. General Trades A roofer earns $24 per hour plus $36 per hour overtime. If he puts in 40 hours of regular time during a certai
snow_tiger [21]

Answer:

He should work 6\frac{2}{3} hours in overtime.

Step-by-step explanation:

Let x represents the number of hours of regular time and y represents the number of hours of overtime,

Since, earnings are $24 per hour for regular time and $36 per hour for overtime,

Thus, total earning = (24x + 36y) dollars,

Here, x = 40 hours and total earning = $ 1200,

By substituting the values,

1200 = 24(40) + 36y

1200 = 960 + 36y

240 = 36y

⇒ y = 6\frac{2}{3}\text{ hours}

Hence, he should work 6\frac{2}{3} hours in overtime.

A baby pool is shaped like a short, wide cylinder and holds 52 ft3 of water. A medium pool measures 4 times the height and width
timama [110]

Answer:

D.\ 3328\ ft^3

Step-by-step explanation:

Given

Volume of baby pool = 52ft³

Required

Determine the volume of the medium pool

Volume of a cylinder is calculated as:

V = \pi r^2h

Hence, the volume of the baby pool is:

\pi r^2h = 52

where r and h are the radius and height of the baby pool

Represent the height and radius of the medium pool as H and R

From the given parameters in the question

H = 4 * h and R = 4 * r

H = 4 h and R = 4  r

The volume of the medium cylinder is calculated as

Volume = \pi R^2H

Substitute 4h for H and 4r for R

Volume = \pi (4r)^2(4h)

Open bracket

Volume = \pi (4r) * (4r) * (4h)

Volume = \pi 16r^2 * (4h)

Volume = \pi 16r^2 * 4h

Collect like terms

Volume = \pi r^2 * h * 4 * 16

Volume = \pi r^2  h * 64

Recall that \pi r^2h = 52

So, the expression becomes

Volume = 52 * 64

Volume = 3328

Hence, the medium pool can hold 3328ft^3 of water

Which is another way to check the sum of 104+34+228+877?
Alex787 [66]
The answer is digit sum method.

Digit sum method is method used to check the sum of sum numbers. If the sum of all of the digits of numbers is equal to the sum of all of the digits of the total sum, then the arithmetic process was correct.

We need to check the sum of <span>104+34+228+877:
</span>104 + 34 + 228 + 877 = 1243

Let's first summarize the digits of individual numbers:
104 *** 1 + 0 + 4 = 5
34 *** 3 + 4 = 7
228 *** 2 + 2 + 8 = 12 *** 1 + 2 = 3
877 *** 8 + 7 + 7 = 22 *** 2 + 2 = 4

Now, let's sum these sums:
5 + 7 + 3 + 4 = 19 *** 1 + 9 = 10 *** 1 + 0 = <u><em>1</em></u>

Then, let's summarize the digits of the total sum:
1243 *** 1 + 2 + 4 + 3 = 10 *** 1 + 0 = <u><em>1</em></u>

Since the sums of the digits on the both sides of equation is 1, than the arithmetic process was correct and the sum of <span>104 + 34 + 228 + 877 is really 1243.</span>
