Answer:
if 100 came by in 2 hours 50 would come by in one hour
Step-by-step explanation:
split it it's by 2
If 100 came by in 2 hours then 50 would come by in one hour.
What is unit rate?There is an independent quantity, and a quantity that depends on it (dependent quantity). When independent quantity moves by a unit measurement (single unit increment), the increment in dependent quantity is called the rate of increment of dependent quantity per unit increment in independent quantity.
We have been given 100 cars pass by in 2 hours
We need to find the unit rate.
Total car = 100
Time = 2 hours
Unit rate = 100/2
Unit rate = 50
Therefore, the unit rate of 50 car in one hour.

Pls help me, I don't know how to do it?:(
Answer and Step-by-step explanation:
Alot of these can be solved with the table up above the problems.
A, B, and C.
According to the table, every time a value has an exponent of 0, it would equal to 1. Since all A B and C values follow the 0 exponent, their value is 1.
D.
According to the table, when we have a negative exponent, the number gets turned into a fraction of [tex]\frac{1}{x^x}[/tex]
Since our value is 9^-2, do as followed :
[tex]\frac{1}{9^2}[/tex]
Solve what is 9^2 :
[tex][\frac{1}{81} ][/tex]
E.[tex]\frac{1}{x^{-5} }[/tex]
This question is different, since we have to go backwards, we have to switch the negative exponent to a positive exponent and rid the fraction.
[tex]x^5[/tex]
F.[tex]5a^3b^{-2}[/tex]
Since we have one negative exponent, follow the fraction rule but instead of having one as the numerator, have 5a^3.
[tex]\frac{5a^3}{b^{2}}[/tex]
Fill in the table :[tex]-3^4 = -3*-3*-3*-3=-81[/tex]
Since -3 is in parenthesis, we can rid the negative along with the parenthesis :
[tex](-3)^4=3^4=3*3*3=81[/tex]
Follow the negative exponent rule :
[tex](-3)^{-4}=\frac{1}{(-3)^4} =\frac{1}{3^4} =\frac{1}{3*3*3*3}= \frac{1}{81}[/tex]
Follow the negative exponent rule yet again :
[tex]-3^{-4}=-\frac{1}{3^4} =-\frac{1}{3*3*3*3} =-\frac{1}{81}[/tex]
A phone company charges $67 for monthly access and $14 for each gigabyte of data used. If you sign a two-year contract and use 147.5 gigabytes of data, what is the total amount you will pay for phone service?
Answer:
the answer is below :)
Step-by-step explanation:
BigBytes will be 100 +10x = y ($100 flat fee plus 10 times the number of gigabytes equals total cost).
GoGig will be 120 + 5x = y. ($120 flat fee plus 5 times the number of gigabytes equals total cost).
Now set them equal to each other and solve for x to find where the gigabytes are the same.
100 + 10x = 120 + 5x
Subtract 100 from both sides: 10x = 20 + 5x
Subtract 5x from both sides: 5x = 20.
Divide both sides by 5: x = 4. 4 gigabytes is the answer.
a brainliest would be appreciated :)
The total amount you will pay for phone service is 4 gigabytes.
What is an equation?An equation is an expression that shows the relationship between two or more numbers and variables.
BigBytes will be 100 +10x = y
Therefore , We have $100 flat fee plus 10 times the number of gigabytes equals total cost).
GoGig will be 120 + 5x = y.
We have $120 flat fee plus 5 times the number of gigabytes equals total cost).
Now set them equal to each other and solve for x;
100 + 10x = 120 + 5x
Now Subtract 100 from both sides:
10x = 20 + 5x
Then Subtract 5x from both sides:
5x = 20.
Now Divide both sides by 5:
x = 4.
Hence, the total amount you will pay for phone service is 4 gigabytes.

Answer and Step-by-step explanation:
Let x be for mimstoons, and y be for naxvips.
The equations would be:
x + y = 60
1x + 4y = 60
x is for the amount of mimstones, while y is for the amount of naxvips, and when we add these together, we get the 60 amount of both the items combined.
With the second equation, we multiply the amount that was bought times the price to get the total price of $60.

What is the area of the figure? O 1240 units? 0 1250 units? o 2490 units? 0 3730 units
Answer:
2490
Step-by-step explanation:
The 2 shapes are triangle and trapezoid
Area of a triangle formula: A= h×b/2
A=40×62/2
A=1240
Area of a trapezoid formula: base¹+base²/2×height
A= 38+62/2×25
A=1250
Add both areas together

What is the solution
-3x + y = 2
y = x + 4
Answer:
to find the solution, we substitute y = x + 4 into the other equation.
-3x + (x + 4) = 2
-3x + x + 4 = 2
-2x = 2 - 4
-2x = -2
x = 1
to find y, we substitute x to the x variable in the y equation.
y = 1 + 4
y = 5
therefore, when combined, it is (1,5).

The graph of f(x) = x2 − 3x − 28 is shown. Which of the following describes all solutions for f(x)?
a parabola passing through negative 4 comma zero, zero comma negative 28, and 7 comma zero
(−4, 0), (0, −28), (7, 0)
(−4, 0), (−1, −24), (0, −28), (3, −28), (7, 0)
(x, x2 − 3x − 28) for all real numbers
(x, y) for all real numbers
Answer:
C. (x, x2 − 3x − 28) for all real numbers
Function graphs are graphs of solution equations for y! In this instance, f(x) = x² -3x -28 is the graph.
Constructing a Function Graph:⇒f(x) = x² − 3x − 28
A group of all points in the plane of the form (x, f(x)) constitutes the diagram of a function f. The graph of f can also be defined as the graph of an equation y = f(x). As a corollary, a function's graph is a subset of an equation's graph.
Solving equation:
⇒f(x) = x² − 3x − 28
⇒f(x) = x² − (7−4)x − 28
⇒f(x) = x² − 7x+4x − 28
⇒f(x) = x(x −7) +4(x −7)
⇒f(x) = (x −7) (x+4)

Need help po. Salamat
Answer:
1. y ≥ 100
2. y ≤ 300
3. y ≥ 20000
4. 2y ≥ 80
5. 2y ≤ 90
Step-by-step explanation:
Let y be the variable.
1. The discount is not less than 100.
If the discount (i.e y) is not less than 100, it means it is either 100 or greater than 100.
This can be written as:
y ≥ 100
2. The cost of the book is at most 300.
This implies that the cost of the book (i.e y) is either 300 or lesser.
This can be written as:
y ≤ 300
3. His monthly income is at least 20000. This simply means that his monthly income (i.e y) is 20000 or greater than 20000.
This can be written as:
y ≥ 20000
4. Twice the number is at least 80.
Let the number be y.
Twice the number y can be written as:
2y
But twice the number is at least 80.
This means that twice the number is 80 or greater than 80. This can be written as:
2y ≥ 80
5. Twice the measure of the acute angle is not more than 90 degree.
Let the angle be y.
Twice the angle can be written as:
2y
But twice the measure of the angle is not more than 90 degree. This implies that twice the angle is 90 or lesser than 90. This can be written as:
2y ≤ 90

3.(x + 2) + (2x + 3) = 23
Answer:
x = 6
Step-by-step explanation:
(x + 2) + (2x + 3) = 23
Combine like terms
3x +5 = 23
Subtract 5 from each side
3x+5-5 = 23-5
3x = 18
Divide each side by 3
3x/3 = 18/3
x = 6
Answer:
x = 6
Step-by-step explanation:
1. Remove parentheses where unneeded. x + 2 + 2x + 3 = 23
2. Add constants. x + 5 + 2x = 23
3. Combine like terms. 3x + 5 = 23
4. Subtract "5" from the constants on both sides of the equation. 3x = 18
5. Divide both sides by 3. 3x/3 = 18/3
6. Simplify. x = 6

Solve each problem. Round to the nearest tenth if necessary. Use 3.14 for π. What is the radius of a circle with a circumference of 15 cm? Show your work! I will be giving out brainliest!
Answer:
2.3
Step-by-step explanation:
First off, you start with the circumference formula which is 2(pi)r. Since we know our circumference, we can create the equation solving for r. so we have 15=2(pi)r. Now in order to solve for r, we need to transfer everything to the other side, meaning dividing by 2(pi). So 15/2(pi)=2(pi)r/2(pi). Since we are using 3.14 for pi, 3.14*2 is 6.28. 15/6.28 which is about 2.388 So the radius of the circle is 2.3 (rounded to the nearest tenth)
