Me.Doherty paints houses. He charges $25.00 per hour plus a flat fee of $50 for a job after painting you owe him $275. How many hours did he spend painting your house

Answers

Answer 1

Answer:

9 hours

Step-by-step explanation:

The total charge was $275 = $50 + ($25/hr)h

Simplifying:  $225 =  ($25/hr)h

                $225

Then h = ---------------- = 9 hours

                 ($25/hr)

Mr. D. spent 9 hours painting.

Which numbers are solutions to the equation 30=x2
? Select all that apply.

x=15

x is equal to 15
x=30−−√
x is equal to square root of 30
x=900
x is equal to 900
x=−15
x is equal to negative 15
x=−30−−√
x is equal to negative square root of 30
x=−900

Answers

Answer:

x = +√30

Step-by-step explanation:

Please write 30 = x squared as 30 = x^2.

If x^2 = 30, there are two solutions:  x = +√30 and x = -√30.

Several possible answers are given.    x=30−−√ is closest to the correct one, but must be written as x = √30.  Please ask someone how to find the "√" operator in Brainly.  Or, just write "sqrt(      )" instead.

Ed stands on a moving walkway and gets from one end of the walkway to the other in 20 seconds. The walkway is 44 feet long. Which statements are true?
Every 8 seconds, Ed travels 32 feet.
Ed travels 11 feet every 5 seconds.
Ed travels 2.2 feet per second.
Ed travels 0.9 of a foot every 2 seconds.
Every 10 seconds, Ed travels 22 feet.

Answers

Answer:
Ed travels 2.2 feet per second.
Every 10 seconds, Ed travels 22 feet.
Ed travels 11 feet every 5 seconds.

Explanation:
Divid feet (44) by the seconds (20) to find out how far Ed can move in a second.
44 ÷ 20 = 2.2
Multiply the feet per second by the seconds in each option to see which is correct.

(I’ll go through them in order of how you listed them)
8 x 2.2 = 17,6 So first one is false
5 x 2.2 = 11 So it’s true
1 x 2.2 = 2.2 So it’s true
2 x 2.2 = 4.4 So it’s false
10 x 2.2 = 22 So it’s true

(Now you know how to do it!) :D

9a^4b^10 ( 4 - 9a^12b^20)

Step-by-step explanation:

The greatest common factor of the two terms is 9a^4b^10

You can now remove the greatest common factor outside the brackets.

Inside the brackets, you place the value obtained by dividing 36a^4b^10- 81a^16b^20 by 9a^4b^10

That is = 4 - 9a^12b^20

Please note that the laws of indices i used for the above division is: n^a divided by n^b = n^(a-b)

Now, the factorised answer for your question =  9a^4b^10 ( 4 - 9a^12b^20)

Diagram B because the points are all over the place.

Answer:

Diagram B

Step-by-step explanation:

Diagram A makes sense to have a line of best fit because there is a common amount of data for where the next points probably will be. The points are close to the line of best fit, and there are pretty much an even amount of points on each side of the line. So, Diagram A’s line of best fit makes sense.

Diagram C makes sense to have a line of best fit because about the line, all the points are right next to it, and the line of best fit gives a nice representation of the data. So, Diagram C’s line of best fit makes sense.

For Diagram B, all of the points all scattered across the graph and none of them are close to the line of best fit, and a line a best fit is usually made to make an estimat of where the data will be, but for example, the point (20,90) is nowhere near the line of best fit. So, Diagram B’s line of best fit should not have been drawn.

First perform the indicated multiplication:  

3(2x+1)=4x+5 becomes 6x + 3 = 4x + 5.

Consolidate like terms:   2x = 2

Solve for x:  x = 1

Answer:

Step-by-step explanation:

To solve the equation, first you would multiply 3 times 2x and 3 times 1.  Then, you would write 6x plus 3 on the right side of the equation.  Then, you would subtract 3 from both sides of the equation.  You then will have 6x=4x+2.  Lastly, you would get an answer of x=1

Volume= 360 feet³

Step-by-step explanation:

We have two shapes, a triangular prism and a rectangular prism.

Rectangular Prism: [tex]w=6, h=2, l=8, V=lwh[/tex]

So, the volume is 6×2×8=96 feet³

Triangular Prism: [tex]h=5.5-2=3.5, w=6, l=8, V=\frac{1}{2}lwh[/tex]

So, the volume is (5.5×6)÷2 ×8= 33×8=264 feet³

We have to combine the two volumes to find the volume of the whole shape. 96+264=360. So, the volume of the whole shape is 360 feet³

X2-12x+21=-6 solve the quadratic by factoring

Answers

Answer:

(x-3)(x-9)

Step-by-step explanation:

first thing you need to do is move the -6 over. so we're going to add 6 to both sides (we add because it's negative 6 and we need 0 on the right side)

so you have: x^2-12x+27

now we need to come up with two numbers that add to -12 and multiply to 27.

the factors of 27 are 9 & 3 and 27 & 1. only 9 & 3 add to 12 so we are going to use those.

since the 12 is negative however, 9 and 3 should both be negative.

therefore we get: (x-3)(x-9)
