Answer:
(7³ + 7³) cubic units
Step-by-step explanation:
The formula for the volume of a cube = (Side length)³
From the question, we are told that, we have two cubes
Cube 1 :
Side length = 7
Volume of cube 1 = 7³ cubic units
Cube 2
Cube 2 also has a side length of 7 as well
Volume cube 2 = 7³ cubic units
We are asked in the question to find the total volume of the cube and express as exponents
Total volume = Volume of cube 1 + Volume of cube 2
=( 7³ + 7³) cubic units

There are 7 students in a class. If there are 3 seats in the front row, how many ways can the students sit in the front row, assuming there are no empty seats?
Answer:
35 different waysStep-by-step explanation:
Since there are 7 students in a classroom to fill a front row containing 3 seats, we will apply the combination rule since we are to select 3 students from the total number of 7 students in the class.
In combination, if r objects are to be selected from a pool of n objects, this can be done in nCr number of ways.
nCr = n!/(n-r!)r!
Selecting 3 students from 7 students to fill the seats can therefore be done in 7C3 number of ways.
7C3 = 7!/(7-3)!3!
7C3 = 7!/(4)!3!
7C3 = 7*6*5*4!/4!*3*2
7C3 = 7*6*5/6
7C3 = 7*5
7C3 = 35
Hence there are 35 different ways that the student can sit in the front assuming there are no empty seats.
how do you solve this system of equation?
2x+4y=-4
3x + 5y =-3
Answer:
x = 4
y = -3
Step-by-step explanation:
We can use substitution, elimination, or graphically.
Step 1: Rearrange first equation
2x + 4y = -4
2x = -4 - 4y
x = -2 - 2y
Step 2: Rewrite systems of equations
x = -2 - 2y
3x + 5y = -3
Step 3: Substitution
3(-2 - 2y) + 5y = -3
-6 - 6y + 5y = -3
-6 - y = -3
-y = 3
y = -3
Step 4: Find x using y
2x + 4(-3) = -4
2x - 12 = -4
2x = 8
x = 4
Graphically:
Use a graphing calc and analyze where the 2 lines intersect.

This is the square root of 6 over 3. The 3 is not inside the square root.
========================================================
Explanation:
sqrt = square root
We have sqrt(6) in the denominator. Your teacher wants you to rationalize the denominator, which means to take out the square root and instead have an integer here.
To achieve this, we multiply top and bottom of the fraction by sqrt(6) like so
[tex]\frac{2}{\sqrt{6}}\\\\\frac{2*\sqrt{6}}{\sqrt{6}*\sqrt{6}}\\\\\frac{2\sqrt{6}}{\sqrt{6*6}}\\\\\frac{2\sqrt{6}}{\sqrt{36}}\\\\\frac{2\sqrt{6}}{6}\\\\\frac{2\sqrt{6}}{2*3}\\\\\frac{\sqrt{6}}{3}\\\\[/tex]
Therefore,
[tex]\frac{2}{\sqrt{6}}=\frac{\sqrt{6}}{3}\\\\[/tex]

Central High School is having their annual spaghetti dinner tomorrow evening, so a team of volunteer cooks is busy preparing for the event. They estimate that each of the 200 guests will eat 1.5 cups of tomato sauce. If the cooks already made 6 gallons of tomato sauce yesterday, how many gallons do they have to make today?
Hint: There are 16 cups in 1 gallon.
Answer:
The answer is 12.75 gallons.
Step-by-step explanation:
What I did to figure this out is I multiplied 200 x 1.5 to figure how many cups there is total. Then I converted the cups to gallons and subtracted 6. I got 12.75 gallons of tomato sauce.

Andy painted 400 square feet in 3 hours.how long will it take him to paint 720 square feet
Answer:
324 minutes or 5.4 hours
Step-by-step explanation:
400/3 = 133.333
133.333/60 = 2.2222
It took him one minute to paint 2.2222 square feet
720/2.2222 = 324 minutes
324/60 = 5.4 hours
Answer:
It will take Andy 5 hours and 24 minutes to paint 720 sq. ft.
Step-by-step explanation:
Since he painted 400 sq. ft. in 3 hours, then do 400/3 to get 133.33... sq. ft per hour. Then, do 720 / 133.33... to get 5.40000000001 hours taken. The 5 represents 5 hours, and the .4 represents 24 minutes (because 60 x .4 = 24).
Overall, you get 5 hours and 24 minutes of time to pain 720 sq. ft.

Scientists believe there is a link between ambient temperature and damage to a head gasket on a car. Using the provided information, draw a scatterplot of the data. Based on the information, what might the approximate damage index be if the temperature was 10° Celsius? A) 5 B) 7 C) 10 D) 13
Answer:
D) 13
Step-by-step explanation:
The lower temperatures have a negative correlation so the lower the temperature the higher the damage index. Therefore a temperature of 10° Celsius should have a damage index higher than that of 12° Celsius so the only option is 13.
is k=3 a reduction or enlargement (dilation)
Answer:
It is an enlargement because k=3 is larger than 1. Anything that equals less than one (ex. k=0.25) would be a reduction.

Answer:
[tex]x = \frac{40}{6} [/tex]Step-by-step explanation:
To solve the equation
(2x - 1) + (4x + 9) = 32
First of all remove the parenthesis
That's
2x - 1 + 4x + 9 = 32
Simplify
We have
6x - 8 = 32
Add 8 to both sides
Thats
6x - 8 + 8 = 32 + 8
6x = 40
Divide both sides by 6
That's
[tex] \frac{6x}{6} = \frac{40}{6} [/tex]
We have the final answer as
[tex]x = \frac{40}{6} [/tex]

Line g passes through the points (-2.6,1) and (-1.4,2.5), as shown. Find the equation of the line that passes through (0,-b) and (c,0).
Answer:
y=-1.25x-4.25
Step-by-step explanation:
I had the same assignment.
The equation of the line that passes through (0,-b) and (c,0) is
7y - 8x = 28
The formula for calculating the equation of a line in point-slope form is expressed as:
[tex]y-y_0=m(x-x_0)[/tex]
m is the slope of the line
(x0, y0) is any point on the line
Given the coordinate points (0, -b) and (c, 0)
Since b = -4 and c = -3.5
The required coordinate points will be (0, 4) and (-3.5, 0)
Substitute the given parameters into the given formula for calculating the slope:
[tex]m=\frac{y_2-y_1}{x_2-x_1}[/tex]
[tex]m=\frac{0-4}{-3.5-0} \\m = \frac{4}{3.5}\\m = 8/7[/tex]
Substitute m = 8/7 and the point (0, 4) into the expression [tex]y-y_0=m(x-x_0)[/tex]
[tex]y-4=\frac{8}{7} (x-0)\\7(y-4)=8x\\7y-28=8x\\7y-8x=28[/tex]
Hence the equation of the line that passes through (0,-b) and (c,0) is
7y - 8x = 28

5. Triangle UVT ~ ∆RSQ by SSS
Step-by-step explanation:
The ratios of side lengths, shortest to longest are ...
VT : TU : UV = 42 : 70 : 84 = 3 : 5 : 6
SQ : QR : RS = 15 : 25 : 30 = 3 : 5 : 6
Side lengths are proportional, so ∆UVT ~ ∆RSQ.

The triangle names need to be chosen so the sides are in the same order. Here UV and RS correspond, as do VT and SQ. That eliminates all but one answer choice.
Researchers recorded that a group of bacteria grew from 200 to 1,000 in 8 hours. At this rate of growth, how many bacteria will there be in 20 hours from the start of the experiment
Answer:
11,180
Step-by-step explanation:
The usual assumption for organic growth is that it is exponential. Here, the number increased by a factor of 1000/200 = 5 in 8 hours. For t in hours, a model for population might be ...
b = (initial value)·(growth factor)^(t/(period of growth))
b = 200(5^(t/8))
Using t = 20, the predicted population is ...
b = 200(5^(20/8)) = 200·5^2.5 ≈ 11,180
There might be about 11,180 bacteria in 20 hours.

A zookeeper has 858585 treats to divide evenly among 888 seals. The zookeeper divides to see how many treats to give to each seal. The zookeeper will have as few treats left as they can.
Answer: 10 treats per seal, and there are 5 treats left.
Step-by-step explanation:
The zookeeper has 85 treats, and want to divide them into seals, in such a way that the treats left is minimized,
Then we want to find the multiple of that is closer to 85 (from below)
We know that: 8*10 = 80 is a multiple of 8, and the next one is:
8*11 = 88, but this is larger than 85, so we discard this option.
Then we will divide 80 treats into 8 seals, and we will have:
85 - 80 = 5 treats left.
Then each one of the 8 seals gets:
80/8 = 10 treats.
