Ryan ordered some books online and spent a total of . Each book cost and he paid a total of for shipping. How many books did he buy?
Answer: 12 books
Step-by-step explanation:
First you need to remove the cost of shipping from the total amount:
= 75 - 3
= $72
The above is the total amount spent on the books without shipping.
If each book cost $6, the total number of books bought is:
= 72 / 6
= 12 books

If each of the two equations shown below are graphed in the same xy-coordinate plane, the graphs intersect. What is the x -coordinate of one of these points of intersection? y = 2x−9 y=−(x−1)2−7
Answer:
The graphs do intersect at two values of x;
x = 1
and
x = -1
Step-by-step explanation:
We have the two equations:
y = 2*x - 9
y = -(x - 1)^2 - 7
We know that when we graph these equations, the graphs do intersect.
if the graphs intersect, then we must have at least one point (x, y) that is a solution for both equations.
because in this point y is the same for both equations, then we can write:
2*x - 9 = y = -(x - 1)^2 - 7
this leads to the equation:
2*x - 9 = -(x - 1)^2 - 7
now we can solve this for x.
2*x - 9 + (x - 1)^2 + 7 = 0
2*x + x^2 - 2*x + 1 + 7 - 9 = 0
x^2 - 1 = 0
x^2 = 1
x = √1
Then we have two possible solutions:
x = 1, and x = -1

A bag contains 19 cards numbered 1 through 19. A card is randomly chosen from the bag. What is the probability that the card has a multiple of 3 on it
Answer: 6/19
Step-by-step explanation:
To solve this question, find out the number of multiples of 3 between the numbers 1 - 19.
The multiples of 3 there are:
= 3, 6, 9, 12, 15 and 18
There are 6 multiples.
Probability will therefore be:
= Number of multiples of 3/ Total number of cards
= 6/19
A cheer squad of 8 cheerleaders raised $317.30. They need $622.42 to
pay for the Homecoming dance. If each cheerleader raises the same
amount, how much more does each cheerleader need to raise?
Answer:
Each cheerleader needs to raise 38.14 more
Step-by-step explanation:
Answer:
They each need to raise $38.14.
Step-by-step explanation:
For this problem, I started off by subtracting 317.30 from 622.42.
(622.42-317.30) This gave us 305.12.
I did this, because we are trying to find the amount of money the cheerleaders have left to make.
Next, we will divide the difference of this equation (305.12) by 8.
We did this because there are 8 cheerleaders, and they all made the same amount of money.
This leaves us with an answer of:
Each cheerleader has exactly $38.14 left to make.
In a physics lab, an artifact is dropped from the roof of the school building, 98 feet above the ground. The height ݄ (in feet) of the ball above the ground is given by the function h(t)=-16t^2+98, where t is the time in seconds.
Answer:
The algebraic expression h = 16 feet.
The length of a basketball court is twice its width. The perimeter is 150 feet. Find the length and width of the basketball court. On your worksheet, solve the question and write your answer below. What is length of the basketball court? What is the width of the basketball court?
Answer: W=25 and L=50
Step-by-step explanation: I first started out with 50, because 50 is half of 100. 50 divided by 2 equals twenty five. Now, I moved on to 100. 100 divided by 2 equals 50. 25+25+50+50=150.
Answer:
The width of the basketball court is 25 feet and the length is 50 feet
Step-by-step explanation:
Equations:
Let's make:
x = width of the basketball court
2x = length of the basketball court
The perimeter of the court is twice the width plus twice the length:
P = 2x + 2(2x)
P = 2x + 4x = 6x
It's known to be 150 feet, thus:
6x = 150
Dividing by 6:
x = 150/6
x = 25 feet
2x = 50 feet
The width of the basketball court is 25 feet and the length is 50 feet

The value of x from the given diagram using the similarity theorem of a triangle is 7
In order to get the value of x from the given triangle, we will use the similarity theorem of a triangle.
From the given triangle, the following equation is true;
5/40 = 3/2x + 10
Cross mutiply
5(2x + 10) = 3(40)
10x + 50 = 120
10x = 120 - 50
10x = 70
x = 7
Hence the value of x from the given diagram is 7

Consider the relationship in special right triangles to determine the tangent ratio for a 45 degree angle. Give your answer, as necessary, to the nearest thousandth place (three decimal place values).
Answer:
1
Step-by-step explanation:
The tangent of a angle is opposite side/ adjacent side
In a rights triangle with a 45° angle we have a special 45-45-90 triangle.
The legs of the triangle are congruent and are the opposite and adjacent sides of the 45° angle. Therefore, the ratio of those two sides is 1.
Therefore, the tangent of 45° = 1
