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.

Answer:
B. 84 in²Step-by-step explanation:
Split the area into two sections by extending 6 in segment.
We get a rectangle of 5 in x 10 in and a trapezoid.
Rectangle:
A = wlA = 5*10 = 50 in²Trapezoid:
A = 1/2(b₁ + b₂)hA = 1/2((15 - 5) + 7)*(10 - 6) = 1/2*17*4 = 34 in²Total area:

3/5 of the sundaes are mint ice cream and 1/2 of the remaining sundaes are chocolate. The rest will be vanilla. How many sundaes will be vanilla?
Answer:
5 sundaes
Step-by-step explanation:
find the GCF: 5
so 3x5 would be 15
15 mint.
25-15=10
10/2=5

Probability is the likelihood that an event will occur and is calculated by dividing the number of favorable outcomes by the total number of possible outcomes.
It is given that, there is \($25$\) sundaes with mint, chocolate and vanilla flavor ice cream out of these \($\frac{3}{5}$\) of the sundaes are mint flavor and \($\frac{1}{2}$\) are chocolate flavor.
We have to find the number for sundaes will be vanilla flavor ice-cream.
So,
We have to multiply \($3$\) by \($5$\) and solve it.
So,
\($3\times 5=15$\)
There are \($15$\) mints flavor.
Now,
Divide total number of sundaes with all flavor ice-cream by calculate value for mint.
We get,
\($25-15=10$\)
Multiply the above calculate value by no. of remaining sundaes for chocolate ice-cream.
So,
\($10\times \frac{1}{2}=5$\)
Hence, there are \($5$\) sundaes will be vanilla flavor ice-cream.

What is the area of the actual garden?
Answer:
the area of the garden is 34
Step-by-step explanation:
in order to solve this problem you would have to essentially just use the formula which is A= length times width
in this case you would have to multiply 4 by 8 1/2 in order to get 8 1/2 into a fraction to make it easier to multiply you would multiply 8 by 2 and add 1 so your fraction would be 16/2. So the denominator 2 cancels with 4 giving you 2 times 17 and that would be 34

Some students recorded how many minutes they spent on the phone in one day. They put the results in a Stem-and-Leaf Plot.
What is the mean number of minutes spent on the phone?
Explanation:
The data from the stem-and-leaf plot is:
10,
24,25,26,
30,30,32,33,
40,45,46
Add up those values
10+24+25+26+30+30+32+33+40+45+46 = 341
Then divide over n = 11 which is the sample size.
341/11 = 31 is the arithmetic mean.
Answer:
341/11 = 31 is the arithmetic mean.

Kimi’s dog gives birth to a litter of 4 puppies per year, on average. The relationship between time and the expected total number of puppies is shown on the graph. Which other ordered pairs would fall on this line? Select all that apply.
(0, 0)
(2, 6)
(3, 12)
(4, 14)
Answer:
(0,0) and (3,12)
Step-by-step explanation:
The ordered pairs that would fall on the line are (0, 0), (1, 4), (2, 8), (3, 12), and (4, 16).
As shown in the graph,
x-axis represents the number of years
y-axis represents the number of puppies.
The slope of the line is 4, which means that for every 1 year that passes, the number of puppies increases by 4.
The y-intercept of the line is 0, which means that if there are 0 years, then there are 0 puppies.
The ordered pairs (2, 6) and (4, 14) do not fall on the line because they do not follow the slope of the line.
For example, in the case of (2, 6), the number of puppies should be 8, not 6.
Therefore, the only ordered pairs that would fall on the line are (0, 0), (1, 4), (3, 12), and (4, 16).
