Lyana is painting her bedroom. Her room is 12’ x 18’. The ceilings are 8 feet high. She will need to put two coats of paint on. How many cans of paint will she need if the square footage of one can is 400 square feet?
Answers
Answer:
2 cans to cover the room but she will have a lot of paint left over
Step-by-step explanation:
12*18=216
the area of her room is 216 square ft.
216*2=432
she will need 2 cans
Answer:
Lyana will need 4 cans of paint to paint her whole room or only 3 if she doesn't paint the floor.
Step-by-step explanation:
Firstly we need to know how much paint she will need to use.
The area of her room is given by 2(ac+bc), where a is the length, b is the width and c is the height.
Applying that we get that the area of her room is 2*12*18+2*18*8=720.
This applies if we assume that she also paints the floor. If she doesn't we need to subtract the area of the floor which is 12*18=216. So 720-216=504
She will paint her room twice she the amount of paint she needs is twice the area:
720*2=1440
or if she does not paint the floor
504*2=1008
Now we answer how many cans is that by dividing by 400 and rounding up.
1440/400=3.6 she needs, therefore, 4 cans
1008/400=2.52 she needs 3 cans

Cell phone company A charges $40 a month, with 500 free minutes and $0.10 a minute after that. Cell phone company B charges $25 a month and all minutes cost $0.05.
Answers
B = 25 + .05M
20 minutes a day for 30 days = 600 minutes per month
A(600) = 40+.1(100) = $50
B(600) = 25 + .05(100) = $30
Plan B is less expensive
40+.1(M-500)= 25+.05M
40-25- .1(500) = .05-.1M
.05M = 35
M= 35/.05 = 700 minutes will have the same cost under plan A or B
40+.1(200) = $60 under plan A
25+.05(700) = $60 under plan B

Step-by-step explanation:
Two points are given, and they are (0, 4) and (3, -4).
The formula for slope is change in y over change in x.
In this case, the change in y is -8, since -4 - 4 = -8.
The change in x is 3, since |0 - 3| = 3.
Thus, the slope is -8/3, which is equal to -2 2/3.

Answers
Answer:
pls give me brainliest
Step-by-step explanation:
A compound event is an event where there are more than 1 type of possibilities. for example, a non compound event like tossing a coin, has only 2 outcomes, either heads or tails, this is one possibility, but while tossing a die, there are various possibilities, like p(getting 1), p(getting even number), p(getting prime number), etc. this is known as a compound event.
a sample space is is where all outcomes of an event is enlisted, for example in tossing a die, sample space is {1,2,3,4,5,6}. and sample space for tossing a coin, {H,T}. Note : if 2 dices are tossed, the number of possibilities or 6^2, because there are 6 possibilities in one die and it will be 6^2 if there are 2.
a tree diagram helps in easily writing down the outcomes easily, here is an example.

Answer: Range and mean = 8 of both
variance of Set X= 4.7
variance of Set Y= 4.6
Step-by-step explanation:
Two sets of data, set X and set Y are given
a.) Range is the difference of the highest value and the lowest value,
Therefore, Range of set X = 12-4=8
Range of set Y = 12-4=8
Now, Mean of a given data set is the average of all the terms present in the given data set
Mean of set X= Σxif/n = (4+5+6+7+16+18+24)/10 = 8
Mean of set Y= (4+5+7+32+20+12)/10= 8
Therefore, both the data sets has same range and mean.
b.) Standard deviation tells about the variability of the date and is given by,
S.D= σ = √∑ ( X − μ )^2/n
S.D of set X= √(16+9+4+1+0+1+16)/10= √4.7
S.D of set Y= √(16+9+1+0+4+16)/10= √4.6
Variance is the square of S.D, that is, σ^2
Therefore, variance of set X=4.6
variance of set Y= 4.7
c.) The calculated variances of set X and set Y are 4.7 and 4.6 respectively. It implies that the data is more distributed or varied in set X than in set Y. In the other words, data in set Y is more consistent data than of set X.

Use the Midpoint Rule with \(n=5\) to estimate the volume obtained by rotating about the y-axis the region under the curve \(y=\sqrt{1+x^3}\), \(0\leq x\leq 1\).
Answers
To estimate the volume using the Midpoint Rule with \(\displaystyle n=5\), we need to divide the interval \(\displaystyle 0\leq x\leq 1\) into \(\displaystyle n\) subintervals of equal width. Since \(\displaystyle n=5\), each subinterval will have a width of \(\displaystyle \Delta x=\frac{1-0}{5}=\frac{1}{5}\).
Now, let's calculate the volume using the Midpoint Rule. The formula for the volume obtained by rotating about the y-axis is:
\(\displaystyle V\approx 2\pi \sum _{i=1}^{n}y_{i}\Delta x\)
where \(\displaystyle y_{i}\) represents the value of the function \(\displaystyle y=\sqrt{1+x^{3}}\) evaluated at the midpoint of each subinterval.
First, let's find the midpoints of the subintervals. Since the width of each subinterval is \(\displaystyle \Delta x=\frac{1}{5}\), the midpoint of the \(\displaystyle i\)-th subinterval is given by:
\(\displaystyle x_{i}=\frac{\Delta x}{2}+\left( i-\frac{1}{2}\right) \Delta x=\frac{1}{10}+\left( i-\frac{1}{2}\right) \frac{1}{5}\)
Substituting \(\displaystyle x_{i}\) into the function \(\displaystyle y=\sqrt{1+x^{3}}\), we obtain:
\(\displaystyle y_{i}=\sqrt{1+\left( \frac{1}{10}+\left( i-\frac{1}{2}\right) \frac{1}{5}\right) ^{3}}\)
Now, we can calculate the approximate volume using the Midpoint Rule:
\(\displaystyle V\approx 2\pi \sum _{i=1}^{5}y_{i}\Delta x\)
Substituting the values of \(\displaystyle y_{i}\) and \(\displaystyle \Delta x\) into the formula, we can evaluate the sum and compute the estimated volume.
