Answer:
100% = 14
75% = 10.5
25% = 3.5
Answer:
100% = 1475% = 10 1/250% = 725% = 3 1/2Step-by-step explanation:
50% if a number is also 1/2 of that number. So, we multiply 7 by 2 to get 14.
Now we know that we need to solve for 25%, 75%, and 100% of 14.
100% of a number is just that number, so 100% of 14 is 14.
To solve for 75% of 14, we multiply 3/4 by 14.
3/4 x 14/1 = 42/4 = 10 1/2
The final number to solve for is 25% of 14.
1/4 x 14/1 = 14/4 = 3 1/2
Find the point of intersection for the two functions through substitution. Show
your work

This means x = -1 and y = 11 pair up together.
================================================
Work Shown:
Set the two functions equal to one another. Solve for x.
f(x) = g(x)
-4x+7 = 2x+13
7 = 2x+13+4x ... adding 4x to both sides
7 = 6x+13
7-13 = 6x .... subtract 13 from both sides
-6 = 6x
6x = -6
x = -6/6 ... divide both sides by 6
x = -1
Use this x value in either function
f(x) = -4x+7
f(-1) = -4(-1)+7
f(-1) = 11
or
g(x) = 2x+13
g(-1) = 2(-1)+13
g(-1) = 11
Whichever function you pick, the input x = -1 leads to the output y = 11.
The point of intersection is (x,y) = (-1, 11)

a group of 31 students is going to visit a museum the total cost of the tickets is 144.15 about how much will each student pay
Answer:
$4.65
Step-by-step explanation:
To figure this out you would divide 144.15 by 31
When you divide it it gives you 4.65 which is how much each student will pay.
one student will have to pay 4.65
you have divided
31/144.15=4.65

khloe bought a giant cookie. in one hour, she ate 4/7 of the giant cookie. which is the closest to the to the fraction of the cookie she had left?
Answer:
She has 3/7 of the cookie left.
Step-by-step explanation:
Divide the cookie into 7 parts, then take away 4 of those parts. how many are left? 3 out of the 7. So therefore you answer would be 3/7.

Mattie Evans drove 200 miles in the same amount of time that it took a turbo propeller plane to travel 800 miles. The speed of the plane was 150 mph faster than the speed of the car. Find the speed of the plane.
Answer:
200mph
Step-by-step explanation:
Speed is expressed using the expression
Speed = Distance/Time
For Mattie
Distance = 200miles
Speed = x
Time taken by mattie = Distance/speed
Time taken by mattie = 200/x ... 1
For the propeller plane:
Distance = 800miles
Speed = x+150 (The speed of the plane was 150 mph faster than the speed of the car)
time taken by the plane = 800/x+150
Since Mattie took the same amount of time that it took a turbo propeller plane to travel, then we will equate both expressions as shown:
200/x = 800/150+x
Cross multiply
800x = 200(150+x)
800x = 30,000 + 200x
800x-200x = 30,000
600x = 30,000
x = 30,000/600
x = 50
Get the speed of the plane
Since the speed of the plane is 150+x
Speed of the plane = 150+50
Speed of the plane = 200mph

Help me. I'm really confused!
Answer:
Step-by-step explanation:
Remember, the first point in a bracket like this (6, 1) is the x coordinate. Here, 6 is your x coordinate. So, if we actually had the line (which we don't have right now, it would be lined up with the number 6 on the x axis. And the second point, 1 here, is the y coordinate. Which tells you where this point falls on the y axis. it would be lined up with the number 1 on the y axis. First, let's work on the parts where you are listing the points. it seems to give you the x coordinate 2 on the first one. So on the x axis which is the horizontal line that says Number of Books Sold, go to the number 2. Then y upward with your mouse and the first point that appears with the x coordinate of 2 (it's the 2nd point if you start from the bottom of the line and go up) has the y coordinate of 20 because if you use your mouse to go left on the same gray line that point is on, you will hit 20 on the line that says Total Amount Payed (this is your y axis). Now, on the next point it just gives you the y coordinate, 40. Which means that it should be on the grey line that hits the number 40 on the Total Amount Payed line (your y axis). So if you find that point and go down with your mouse on the gray line right under it, you should hit 4. So that point is (4, 40). 6 is not labeled but it is the gray line after the 5 on the x axis. If you go up 6, you hit the to right corner of the graph and if you trace it to the y-axis, it's not labeled but it should be 60 because if you pay attention, the numbers on the y-axis are going up by 10s. The x coordinate represents The Number of Books Sold because it says that under the x axis. The y coordinate represents the Total Amount Payed (dollars). ordered pairs are like ratios because they are both pairs. Ordered pairs tell you how much to go up, down, forwards, and backwards on a coordinate plane while ratios tell you a proportion. I am including a picture to help you out. I hope this made sense and was helpful!
