At a company a copy machine prints 175 pages in 5 minutes if the number of pages printed is proportional to the time in minutes what is the unit rate?
If the copy machine prints 175 pages in 5 minutes and the number of pages printed is proportional to the time in minutes , the unit rate is 35 pages per minute.
What is division?Division is the process of determining the quotient of a number. It is the process of grouping a number into equal parts using another number.
What is the unit rate?The unit rate can be determined by dividing 175 by 5
Unit rate = 175/5 = 35 pages per minute.

HELPP! ASAP PLS!! Find the surface area of the composite solid. Leave your answer in exact terms.
Answer:
Step-by-step explanation:
First find the surface area of the clyinder and find the area circles and subtract
Then find the surface area of a cone, remove the circle area and double it.
Clyinder surface area (without circle area) 2πrh+2πr2=2·π·4·6+2·π·42≈251.32741
251.32741 - 50.2 - 50.2
Cone area: A=πr(r+h2+r2)=π·4·(4+32+42)≈113.09734
113.09734 - 50.2 - 50.2
Total: 12.69734 + 150.92741 = 163.62475

Answer: 190 m³
Step-by-step explanation:
We will calculate the volume of the prisms separately, and then add them together.
V = L * W * H
[1]
V = L * W * H
V = 9 * 2 * 5
V = 90 m³
[2]
V = L * W * H
V = 5 * 5 * 4
V = 100 m³
[Adding together]
100 + 90 = 190 m³
The volume is 190 m³
Paul is decorating cupcakes. He can decorate 3/4 of a cupcake per minute. At this rate, how many cupcakes can he decorate in 12 minutes?
Answer:
3/4 x 12/1 because if you can decorate 3/4 a cupcake per minute, you multiply 3/4 by 12 to find the total amount of cupcakes he could decorate. 3/4 x 12/1 = 9 Paul can decorate 9 cupcakes in 12 minutes.

Nancy wants to buy a sweater that is priced at $75. If the store is running a 60% off sale, what will be the
amount of the discount and the sale price of the sweater?
Answer:
$30.00
Step-by-step explanation:
The original price of the sweater is $75.00. The new sale price is the original price of 100% less 60% of the original price. That means the sales price is 40% of the original price.
You can do this 2 ways:
1. $75 x 60% or .60 = $45
$75-45 = $30
or
2. $75 x 40% or .40 = $30

$2000 should be invested into checking with interest rate 3% and savings account with interest rate 5% so that the total interest will be $84. How much should be invested into each account?
Answer:
$800 at 3%, $1,200 at 5%
Step-by-step explanation:
[tex].03x - .05(2000 - x) = 84[/tex]
[tex]100 - .02x = 84[/tex]

1. determine if the functions are inverse functions
f(x) = x+6
g(x) = x-6
2. determine if the functions are inverse functions
f(x) = -3x-9
g(x) = -1/3x-3
Answer:
Question 1
The function [tex]f(x) = x + 6[/tex] is one-to-one, so it does have an inverse.
The inverse of +6 is -6, so [tex]f^{-1}(x)=x-6[/tex]
Therefore, g(x) is the inverse of f(x).
Question 2
The function [tex]f(x) = -3x -9[/tex] is one-to-one, so it does have an inverse.
To find the inverse, replace f(x) with y:
[tex]\implies y = -3x -9[/tex]
Rearrange the equation to make x the subject:
[tex]\implies y+9= -3x[/tex]
[tex]\implies x=-\dfrac13(y+9)[/tex]
[tex]\implies x=-\dfrac13y-3[/tex]
Replace x with [tex]f^{-1}(x)[/tex] and y with x:
[tex]\implies f^{-1}(x)=-\dfrac13x-3[/tex]
Therefore, g(x) is the inverse of f(x).

Am I starting this off right? What does it mean to find instantaneous velocity?
Answer:
yesv(t) gives the instantaneous velocity at time t(a) correct
(b) -48 ft/s
(c) -32 ft/s; -64 ft/s
(d) 9.257 s
(e) -296.216 ft/s
Step-by-step explanation:
You are given an equation of motion and asked to find velocity and time at different points in the motion. This requires you differentiate the position function to find velocity, and that you solve the position function to find the time at a particular position.
__
(a)The coin is "dropped", so is presumed to have no initial velocity. The initial height is given as 1371 feet. Putting these values into the given equation, you have ...
s(t) = -16t² +1371
The velocity is the derivative of this function:
v(t) = -32t
__
(b)The average velocity on an interval is the change in position divided by the change in time:
(s(2) -s(1))/(2 -1) = ((-16·2² +1371) -(-16·1² +1371))/1 = -16(4 -1) = -48 . . . ft/s
(Note: the average velocity for a quadratic position function is the velocity at the midpoint of the interval: v(1.5) = -32(1.5) = -48 . . . ft/s.)
__
(c)Use the velocity function you found in part (a) to determine the instantaneous velocity at the given times:
v(1) = -32(1) = -32 . . . ft/s
v(2) = -32(2) = -64 . . . ft/s
__
(d)The coin will reach the ground when s(t) = 0. Solving for t, we find ...
s(t) = 0
-16t² +1371 = 0
1371 = 16t²
t = √(1371/16) = (√1371)/4 ≈ 9.257 . . . . seconds
__
(e)The velocity at impact will be ...
v(√1371/4) = -32(√1371/4) = -8√1371 ≈ -296.216 . . . ft/s
