Carlos bought a new computer printer for $110.50 and some ink cartridges
for $8.25 each. He spent a total of $176.50.
The equation $176.50 = $110.50 + $8.25c can be used to solve this
problem. Which two mathematical operations do you need to perform in
order to solve the equation for c?
A. addition and multiplication
B. division and multiplication
C. subtraction and division
D. multiplication and subtraction
Answers
This is because to solve for C you need to isolate it. So you subtract 110.50 to both sides and then divide the product by 8.25 to get C. Therefore you subtract and divide to solve the equation for C.

Write the equation of each circle
Center (-1,0) and containing the point (2, -4)
A.(x + 1)2 + y2 = 25
B.x2 + (y2 +1)= 25
Answers
Answer:
The equation of the circle is [tex](x + 1)^2 + y^2 = 25[/tex]
Step-by-step explanation:
Equation of a circle:
The equation of a circle of centre [tex](x_c,y_c)[/tex] has the following format:
[tex](x - x_c)^2 + (y - y_c)^2 = r^2[/tex]
In which r is the radius.
Center (-1,0)
This means that [tex]x_c = -1, y_c = 0[/tex]. So
[tex](x - x_c)^2 + (y - y_c)^2 = r^2[/tex]
[tex](x - (-1))^2 + (y - 0)^2 = r^2[/tex]
[tex](x + 1)^2 + y^2 = r^2[/tex]
Finding the radius:
Distance between the radius and the centre and a point of the circle. In this case, point (2,-4). Using the formula for the distance between two points:
[tex]r = \sqrt{(2-(-1))^2+(-4-0)^2} = \sqrt{3^2 + 4^2} = \sqrt{25} = 5[/tex]
So, the equation of the circle is:
[tex](x + 1)^2 + y^2 = 5^2[/tex]
[tex](x + 1)^2 + y^2 = 25[/tex]

To investigate whether or not sending text messages while driving impacts driving ability, we had 100 participants (50 men and 50 women) drive an obstacle course under one of the following conditions: 1) no texting while driving, 2) sending five text messages while driving, or 3) sending 10 text messages while driving. We measured the accuracy with which the subjects drove the obstacle course from a scale of 1 to 10 (1 = poor and 10 = excellent).We are testing the effect of sending text messages at three different _____.
a. treatments
b. levels
c. factors
d. None of the above

Answer:
5) $82
6) 300
Step-by-step explanation:
If y=x is your linear regression equation, and if x = temperature and y = $ of ice cream sales, then...
5) x = 82, and given that y=x, then y = $82
6) y = $300, and given that y=x, then x = 300
This doesn't really require algebraic calculation, so I wonder if the linear regression equation obtained from the scatter plot is correct.

A paper company produces 2,985 notebooks in 3 days. How many notebooks can it produce in 11 days?
Answers
Answer:
10080
Step-by-step explanation:
2985÷3=995×11=10080
Answer:
It can produce 32,835 in 11 days.
Step-by-step explanation:
2,985 x 3 = 8,955
2,985 x 3 = 8,955
2,985 x 3 = 8,955
If you add another three, that'll be 12, so, we'll multiply 2,985 x 2.
2, 985 x 2 = 5,970
Now, Add all of those 4 numbers together,
8,955 + 8,955 + 8,955 + 5,970 = 32,835

Step-by-step explanation:
volume of a rectangular prism is V=LWH
L is length and that is 20
W is width and that is 20
H is height and that is 6
The reason that L and W are 20 is because you would multiply those to get the base, and the base is already given, 400.
Since you know the volume is 2,400, a quick trick is that you divide 2,400/400. That equals 6.
So 20 x 20 x 6 = 2400
