Answer:
24 in^3
Step-by-step explanation:
Volume of the figure= 3 * (Volume of a cube with side 2)
Volume of the figure= 3*2^3=24 in^3
Answer:
24 cubic inches
Step-by-step explanation:
The formula for finding volume is b*h*w.
b*h*w is base multiplied my height multiplied my width. Lets use this formula to find the volume of one of cubes.
Here is the information we know about the cubes:
the base is 2 inches
the height is 2 inches
the width is 2 inches
Lets put this information into the formula to find the volume of one of the cubes. I will show the work in steps so it is easy to follow.
Step one: plug the given information into the formula.
b*h*w = 2*2*2
Step two: Solve the equation.
2*2*2 = 4*2 = 8
Now we have the volume of one on the cubes. This is 8 cubic inches. However, to find the volume of all three of the cubes we must multiply 8 by 3.
Step three: multiply 8 by 3.
8*3 = 24
And there you have it! Our final answer is 24 cubic inches.
Here is a quick review of what we did to get our answer:
2*2*2 = 8
8*3 = 24
I hope this helps!

Some food is able to keep 150 students fed at camp for 5 days,
How many days will the food last for if there are 100 students,
I know its 7.5 but why do people x the 150 and 5 i dont get it
Answer:
x=7.5
Step-by-step explanation:
s is for students
d is for days
150 s take 5 days to finish food
if there are 100 s how many days will the same amount of food take
so 150 students × 5 days = 750 equation 1
100 students × x days= 100x equation 2
750 from 1 = 100 x from 2
750÷100=x
x=7.5 days

A group of friends is addressing wedding invitations. Casey can address 22 envelopes in one hour, Anne can address 48 envelopes in two hours, and Paula can address 62 envelopes in three hours. About how long will it take them to address 420 envelopes?
A.
19.09 hours
B.
22.00 hours
C.
7.24 hours
D.
6.30 hours
Answer:
D
Step-by-step explanation:
Let's say that we have x amount of hours.
Casey addresses 22 envelopes per hour. Another way of writing this is that for x hours, Casey addresses 22 envelopes. Therefore, given x hours, Casey addresses 22 * x envelopes.
Anne can address 48 envelopes in 2 hours. It is important to note that this is for 2 hours. To make this per 1 hour, we can write
48 envelopes = 2 hours
divide both sides by 2
24 envelopes = 1 hour.
Therefore, given x hours, Anne addresses 24 * x envelopes.
Paula can address 62 envelopes in 3 hours, so
62 envelopes = 3 hours
divide both sides by 3
62/3 envelopes = 1 hour
Given x hours, Paula can address 62/3 * x envelopes.
Adding all of these up, given x hours, the group of friends can address
22 * x + 24 * x + 62/3 * x envelopes. Because the variables are all the same (x), we can add up the coefficients, resulting in
(22 + 24 + 62/3) * x = (46 + 62/3) * x envelopes given x hours
We want to figure out the amount of hours (x) for 420 envelopes. The total amount of envelopes is equal to (46 + 62/3) * x, so we set 420 equal to that, resulting in
(46 + 62/3) * x = 420
divide both sides by (46 + 62/3) to isolate x
420 / (46 + 62/3) = x
= 6.3 hours

The total cost of 2 bracelets and 3 necklaces is $15.50. The total cost of 4 bracelets and 1 necklace is $13.50. Let b represent the cost of each bracelet and n represent the cost of each necklace. This situation can be represented by the following system of equations.
{2b+3n=15.504b+n=13.50
What is the cost of one bracelet?
A
$2.50
B
$7.75
C
$5.00
D
$3.50
Answer:
A
$2.50
Step-by-step explanation:
b = cost of bracelet
n = cost of necklace
2b+3n = 15.50
4b+1n = 13.50
Multiply the first equation by -2
-4b -6n = -31
4b +n = 13.50
---------------------------
-5n = -17.50
Divide each side by -5
-5n/-5 = -17.5/-5
n = 3.50
Now we can find b
4b+n = 13.50
4b+3.50 = 13.50
4b+3.50-3.50 = 13.50 -3.50
4b = 10
Divide by 4
4b/4 = 10/4
b = 2.50

Answer:
[tex]\displaystyle \frac{1}{\sin^2x}-\frac{1}{\tan^2x}=1[/tex]
Step-by-step explanation:
Prove that:
[tex]\displaystyle \frac{1}{\sin^2x}-\frac{1}{\tan^2x}=1[/tex]
Recall that by definition:
[tex]\displaystyle \tan x=\frac{\sin x}{\cos x}[/tex]
Therefore,
[tex]\displaystyle \tan^2x=\left (\frac{\sin^2x}{\cos^2x}\right)^2=\frac{\sin^2x}{\cos^2x}[/tex]
Substitute [tex]\displaystyle \tan^2x=\frac{\sin^2x}{\cos^2x}[/tex] into [tex]\displaystyle \frac{1}{\sin^2x}-\frac{1}{\tan^2x}=1[/tex]:
[tex]\displaystyle \frac{1}{\sin^2x}-\frac{1}{\frac{\sin^2x}{\cos^2x}}=1[/tex]
Simplify:
[tex]\displaystyle \frac{1}{\sin^2x}-\frac{\cos^2x}{\sin^2x}=1[/tex]
Combine like terms:
[tex]\displaystyle \frac{1-\cos^2x}{\sin^2x}=1[/tex]
Recall the following Pythagorean Identity:
[tex]\sin^2x+\cos^2x=1[/tex] (derived from the Pythagorean Theorem)
Subtract [tex]\cos^2x[/tex] from both sides:
[tex]\sin^2=1-\cos^2x[/tex]
Finish by substituting [tex]\sin^2=1-\cos^2x[/tex] into [tex]\displaystyle \frac{1-\cos^2x}{\sin^2x}=1[/tex]:
[tex]\displaystyle \frac{\sin^2x}{\sin^2x}=1,\\\\1=1\:\boxed{\checkmark\text{ True}}[/tex]

Three sizes of popcorn buckets are on sale at a movie theatre. The large bucket holds 15 1/2 cups of popcorn. The medium bucket holds 1/3 of the amount of the large bucket. The small bucket holds 2/4 of the amount of the medium bucket. How many cups does the medium bucket hold?
Here we have a problem of algebra. We will find that:
The medium bucket can hold 5 and 1/6 cups of popcorn.
Remember that for mixed numbers, like "4 and 1/5", the way of writing that number is (4 + 1/5).
Now, let's solve the question:
We know that the large bucket holds (15 + 1/2) cups.
We also know that the medium bucket holds 1/3 of the large bucket, and we want to know how many cups does the medium bucket hold.
This is just (1/3) times the amount that the large bucket holds, so we have:
(1/3)*(15 + 1/2) cups
Using the product distributivity, we can write:
(1/3)*(15 + 1/2) cups = ( (1/3)*15 + (1/3)*(1/2) ) cups = (5 + 1/6) cups
Then we can conclude that the medium bucket can hold 5 and 1/6 cups of popcorn.

Step-by-step explanation:
17. According to the question, gravel is 4/13 of the total asphalt substance. One parking lot has 260 tons of asphalt. So this means there is 80 tons of gravel because 260 times 4/13=80. We need to find the tons of gravel if we made 3 parking lot. This means 3 parking lot is the same as 780. So we can just find the measure of gravel by multiplying
4/13 by 780.
[tex] \frac{4}{13} \times 780 = 240[/tex]
So there is 240 tons of gravel. C is the answer.
18. Set up system of equations.
[tex]a + b + c = 110[/tex]
The ratio of a to c is 1:7 and the ratio of b to c is 3:7. Using this information,
C is 7 times more than A.A is 3 times less than BUsing this info, we can make alternate equations
[tex]c = 7a[/tex]
[tex]b = 3a[/tex]
Subsitue this into the original equation,
[tex]a + 7a + 3a = 110[/tex]
[tex]11a = 110[/tex]
[tex]a = 10[/tex]
We need to find c, c is 7 times more than a so c is
[tex]c = 10 \times 7 = 70[/tex]
Determine the slope for the equation.

A gas station has monthly expenses in dollars of 5000+2.2 X. It sells the gas at $2.25 per gallon. How many gallons do they need to sell to make a profit of $3000 per month
The number of gallons to be sold in a month is 160,000 gallons.
Your question is incomplete. It looks like you are referring to this question below:
A gas station has monthly expenses in dollars of 5000+2.2 X. It sells the gas at $2.25 per gallon. How many gallons do they need to sell to make a profit of $3000 per month, if X is the number of a gallons sold.
The given parameters include;
total monthly expenses, t = $(5000 + 2.2x)
number of gallons sold, = x
price of a gallon, p = $2.25
estimated profit in a month, g = $3000
The equation for profit made in a month is as follows;
Total revenue - expenses = profit
2.25x - (5000 + 2.2x) = 3000
2.25x - 5000 - 2.2x = 3000
0.05x = 8000
x = 8000/0.05
x = 160,000 gallons
Therefore, the number of gallons to be sold in order to make the estimated profit in a month is 160,000 gallons.
