Mrs. Jones wants to paint the back wall of her classroom light blue. If the dimensions of the wall is 20 feet by 12 feet, how much paint will she need to paint her classroom wall? Round to the nearest tenth if necessary.
Answer:
The total area of the back classroom wall is (20ft x 12ft) = 240ft²
The paint coverage is usually rated by area coverage. For example, one gallon of paint is expected to cover 400 ft².
Assuming a gallon of paint will cover 400ft², she will need (240ft²/400ft²) = 0.6 gallon of paint to cover the entire wall.
Mrs. Jones will need 0.6 gallon of paint to paint the back classroom wall.

Rise over run is the slope, m
m=2/5
a) the slope is 2/5 = .4 which is below the boundary guideline. So no this is not with in carpenter's guidelines
b) the image below show a line with slope 2/5 but with intercept 3
c) the stairs can be draw on the line with rise 2 run 5 from the line. see image
d)equation is in image

a) count the squares
horizontal distance =3
vertical distance =3
b) slope is vertical distance over horizontal distance so m= 3/3 =1

The school band is putting on a concert. Eight students signed up to play the trumpet, 8 students signed up to play the flute, and 8 students signed up to play the violin. Which circle graph could be used to display the data?
A circle graph is split into 3 sectors of approximately 60 percent, 15 percent, 25 percent.
A circle graph is split into 3 sectors of approximately 50 percent, 25 percent, 25 percent.
A circle graph is split into 3 sectors of approximately 33 percent, 33 percent, 33 percent.
A circle graph is split into 3 sectors of approximately 70 percent, 15 percent, 15 percent.
The same amount of students play different instruments so the answer should be:
3 sectors (because there are three different instruments) with 33% in each of them.
Answer: The answer will be C
Because 8 students signed up to play the trumpet, 8 students signed up to play the flute, and 8 students signed up to play the violin. Which means it is equal to each other.
Triangle NGM is reflected across the x-axis, and is dilated by a factor of
\(2 \frac{1}{2} \)
what are the coordinates of vertices N'G'M'
The coordinates of vertices N'G'M' are N'(-10, -15), M'(-15, -5) and G'(-5, -10).
From the given graph, N(-4, 6), M(-6, 2) and G(-2, 4).
Scale factor = \(2\frac{1}{2}\)
= 2.5
The reflection of point (x, y) across the x-axis is (x, -y).
Here, N(-4, 6)→(-4, -6)
M(-6, 2)→(-6, -2)
G(-2, 4)→(-2, -4)
Now, with scale factor 2.5, we get
(-4, -6)→2.5(-4, -6)→N'(-10, -15)
(-6, -2)→2.5(-6, -2)→M'(-15, -5)
(-2, -4)→2.5(-2, -4)→G'(-5, -10)
Therefore, the coordinates of vertices N'G'M' are N'(-10, -15), M'(-15, -5) and G'(-5, -10).

The first sequence rule is multiply by 4 starting from 7. The second sequence rule is add 5 starting from 8. What is the first number that appears in both sequences?
Answer: The first number that appears in both sequences is 28.
Step-by-step explanation:
Let's write down numbers from each of the sequences
Sequence 1) We need to start from 7 and multiply 4
7x4=28, 28x4=112
The sequence is 7,28,112...
Sequence 2) We need to start from 8 and add 5
5+8=13, 13+5=18, 18+5=23, 23+5=28
The sequence is 8,13,18,23,28...
They both have 28
28 is the first number that appears in both sequences.
multiply by 4 starting from 7
First sequence: 7 * 4 = 28 *4 = 112 * 4 = 448add 5 starting from 8
Second sequence: 8 + 5 = 13 + 5 = 18 + 5 = 23 + 5 = 28How the heck did we go from this, to this…

Answer:
Step-by-step explanation:
Let’s mark the Triangle Points as Point A, Point B, Point C.
Point A = 1x°
Point B = 2x°
Point C = 3x°
We know that the Angle Sum of a Triangle is equal to 180°.
So, Point A + Point B +Point C = 180°
= 1x° + 2x° + 3x° = 180°
= (1 + 2 + 3)x° = 180°
= 6x° = 180°
= x° = (180/6)°
= x° = 30°

A river drops 12 ft vertically over a horizontal distance of 1500 ft.
What is the slope of the river?
Answer:
Slope = rise / run
= -12 / 1500 (It's -12 and not 12 because a drop means it's decreasing)

A glass case is in the shape of a rectangular prism. The volume of the case is `4/125` cubic foot. How many cubic blocks with a side length of `1/5` foot would be required to find the volume of the glass case?
Answer: 4 blocks
Step-by-step explanation: if the block is 1/5 ft long on each side, the volume is 1/5³
That is 1/5 ×1/5× 1/5
So its volume is 1/125 cubic ft.
It takes 4 to fill 4/125 cu.ft.
