Answer:
The unit rate is $3.20
Step-by-step explanation:
Unit rate is how much 1 unit of the material costs. So in our case the material is the ribbon. In order to find the unit rate we need to find how much does 1 foot of ribbon cost, we do that by dividing the total cost by the total number of feet, so we do...
19.20 / 6 = 3.20
Therefore the unit rate is $3.20

Answer:
choice 1) x = 2
Step-by-step explanation:
7x-6 = 12-2x because point B is in the middle of AC
reduce:
add 2x to each side:
9x-6 = 12
add 6 to each side:
9x = 18
divide both sides by 9:
x = 2
You spent $175 on a pair of shoes and three shirts. Each shirt cost the same amount. The shoes cost four times the amount of one shirt.
A) Graph the system of equations.
B) What was the price of the shoes and each shirt?
Please answer and take seriously will give brainliest
Step-by-step explanation:
1. making the equation:
shoes = x
shirts = y
175 = x + 3y
x = 4y
2. graph it (I'm using desmos)
the green line is for 175 = x + 3y and the purple one is for x = 4y
3. find the price
x = 4y
175 = 4y + 3y
175 = 7y
y = 175/7 = $25
price of the shirt = $25
x = 4y = 4*25 = $100
price of a pair of shoes = $100

Andrew is paid £250 a week.
Each week, he
shares his pay with his sister in the ratio 3 : 2
saves 12% of his share.
How many weeks will it take Andrew to save £360?
Answer:
20 weeks
Step-by-step explanation:
The calculation of The number of weeks it will take to save £360 is given below:
Now $250 should be divided into a ratio of 3:2
He keeps = 150
And, he gives her = 100

its hard to explain but pretty much if you didn't know the ^x+1 is the x intercept except when its graphed its no marked at (1,0) its mark ate (-1,0) because it always takes the inverse
if you go over to the right 3 then your adding 3 to the x intercept or subtracting 3 from ^x+1 so it would be ^x-2
the y intercept part is easy all you have to do is subtract 2 from the y intercept so it would be +2

If you can, show work. Thanks❤️
Step-by-step explanation:
A camera is positioned 5000 ft from the base of a rocket launching pad. the angle of elevation of the camera has to change at the correct rate in order to keep the rocket in sight. also, the mechanism for focusing the camera has to take into account the increasing distance from the camera to the rising rocket. let's assume the rocket rises vertically and its speed is 800 ft/s when it has risen2548 ft. (round your answers to three decimal places.)
Answer: B
Step-by-step explanation:
We are given an angle and a distance, and to solve for the height we need to make a triangle.
First, I'm going to assign sides to the triangle:
Side a: This is going to be the distance from the camera to the launch pad.
Side b: This is going to be the distance from the launch pad to the rocket (the rocket's height)
Side c: This is going to be the distance from the rocket to the camera (this is the hypotenuse of the triangle)
Now that we have sides, we can solve for the height. The height is the distance from the launch pad to the rocket, so it will be side b. We know that the camera is 5000 ft away from the launch pad, so we can say that side a is 5000 ft. It also tells us the camera is angled up at 27 degrees, so we can say angle B is 27 degrees.
We have a known side that length that is adjacent to a known angle inside of a right triangle, and we want to find the length of the opposite side. In this situation we can use the function tangent.
tan(theta) = opposite / adjacent
If we plug values into this equation we get:
tan(B) = b / a
tan(27 degrees) = b / 5000
b = tan(27 degrees) * 5000
b = 2547.627
b rounded to the nearest foot is 2548 ft, which is answer B

f(x)= x^2 - 4x / x^2 - x - 2
find the x and y intercepts
find vertical and horizontal asymptotes
determine the holes
Step-by-step explanation:
First, I decided to determine the vertical asymptote! You can determine the vertical asymptote by taking the denominator and setting it equal to zero.
−4x+4=0
−4x=−4
x=1
There's a vertical asymptote at x=1.
Now for the horizontal asymptote! The horizontal asymptote is determined by looking at the leading coefficients in the numerator and denominator. Here's a helpful visual.
content://com.cryptotab.android.FileProvider/images/screenshot/16159519510813476709092178134526.jp
In our case, the leading coefficient in the numerator (x2) is larger than the leading coefficient in the denominator (−4x). This means there is no horizontal asymptote!
In some cases, a slant asymptote may be present in a graph. These are sometimes present in graphs that have a stronger leading coefficient in the numerator than the denominator. To determine the slant asymptote, we need to divide the numerator by the denominator.
content://com.cryptotab.android.FileProvider/images/screenshot/16159520052041557972364765603410
The slant asymptote is y=−x4−1
Holes are determined by finding numbers that when plugged into x, return undefined. On a graphing calculator these values will give us an error. Luckily for us, there are no holes, so we can move on.
X-intercepts are values that make the numerator equal zero. We can find these by setting the numerator equal to zero and solving.
x2+3x=0
x(x+3)=0
x+3=0
x=−3
Another number that makes the numerator equal zero is, well, zero!
x2+3x=0
(0)2+3(0)=0
0=0
So we know our x-intercepts are 0 and -3.
To find the y-intercepts, set x equal to zero and solve the equation!
y=x2+3x−4x+4
y=(0)2+3(0)−4(0)+4
y=04
y=0
So we have a y-intercept at y=0!

If a wheel makes 12 of a rotation in 2 seconds, what is the angular velocity, in radians per second?
Answer:
angular velocity = 12π Radians per second
Step-by-step explanation:
The angular velocity is a measure of the rotation/revolution speed of an object, relative to another point.
In order to present the answer in radians per second, let us first establish the relationship between radians and rotations/revolution.
one complete revolution = 360° = 2π Radians
∴ 1 roration = 2π Radians
12 rotations = 12 × 2π Radians = 24π Radians
Angular velocity in radians = 24π Radians in 2 seconds
Now let us convert to radians per seconds.
24π Radians = 2 seconds
2 seconds = 24π Radians
∴ 1 second = (24π Radians) ÷ 2
1 second = 12π Radians
∴ angular velocity = 12π Radians per second

To get as many people as you can to attend the game, you decide to come up with a ride-sharing app, but you want to be sure it will be used before you put all the time in to creating it. You determine that if more than three students share a ride, on average, you will create the app.
You conduct simple random sampling of 20 students in a school with a population of 300 students to determine how many students are in each ride-share (carpool) on the way to school every day to get a good idea of who would use the app. The following data are collected:
6 5 5 5 3 2 3 6 2 2
5 4 3 3 4 2 5 3 4 5
