Michael sold 220 candy bars to support his school band. Payday candy bars sold for $2 each and Baby Ruth bars sold for $3 each. Michael sold $600 worth of candy bars.
1. Set up the two equations that describe this situation.
2. How many Baby Ruth bars did Michael sell?
Answer:
See below
Step-by-step explanation:
Let the number of Payday be p and Baby Ruth be b
Then sub of the candy bars:
p + b = 220Payday candy bars worth ⇒ $2pBaby Ruth candy bars worth ⇒ $3bTotal ⇒ $6001. Required equations:
p + b = 2202p + 3b = 6002. Solving by substitution:
p = 220 - b, consider it in the second equation
2(220 - b) + 3b = 600660 - 2b + 3b = 600660 + b = 600b = 660 - 600b = 6060 Baby Ruth candy bars sold

calculate the rate of change on this graph
Answer: The slope is 2
Step-by-step explanation: For questions like these, find 2 points on the graph that are on whole numbers, for example (10,60) and (20,80). Then use the formula y2-y1/x2-x1 to solve for the slope, which would be the same thing as rate of change. 80-60/20-10 which equals 2. The slope would be 2.

The number of miles in a day at which the rental costs for company a and company b are the same are 350 miles.
Let the number of miles travelled be 'x';
According to question; for rental costs to be same;
120 + 0.40x = 50 + 0.90x;

Find the length of RS.
a) About 6.3 units
b) 8 units
c) About 2.8 units
d) 40 units
(pls help :,) )
Answer:
i is about 23.5 so you could say c)
Step-by-step explanation:
The line segment is RST.
Since RS is 1/3 of the total length, ST is 2/3.
Therefore, 2(RS) is = ST, and RS + ST = RT.
2(3x -20) = 4x - 11
6x - 40 = 4x - 11
2x = 29
x = 14.5
3(14.5) - 20 = 23.5
4x - 11 = 47
2(23.5) = 47
The length of RS is 23.5.
The length of ST is 47.
The total length of RT is 70.5.

2x + 10 =- 4x – 9
Answer:
x = -19/6
General Formulas and Concepts:
Pre-Algebra
Order of Operations: BPEMDAS
Brackets Parenthesis Exponents Multiplication Division Addition Subtraction Left to RightEquality Properties
Step-by-step explanation:
Step 1: Define Equation
2x + 10 = -4x - 9
Step 2: Solve for x
Add 4x on both sides: 6x + 10 = -9Subtract 10 on both sides: 6x = -19Divide 6 on both sides: x = -19/6Step 3: Check
Plug in x into the original equation to verify it's a solution.
Substitute in x: 2(-19/6) + 10 = -4(-19/6) - 9Multiply: -19/3 + 10 = 38/3 - 9Add/Subtract: 11/3 = 11/3Here we see that 11/3 does indeed equal 11/3.
∴ x = -19/6 is the solution to the equation.

A town is storing salt for the winter in a cylindrical building. The building has a radius of 5 ft and is 30 ft tall. The building contains 1,500 ft3 of salt. What is the approximate height that the salt reaches in the building?
The answer are:
A. 0.5 ft
B. 5 ft
C. 19 ft
D. 22 ft
Answer:
To start off, we know the problem involves something with volume as it is 3D and has a cubic in it.
We know r = 5, h = 30, and v = 1500
The volume for a cylinder in 3d is : V=[tex]\pi[/tex][tex]r^{2}[/tex]h
We're solving for the height when the cylinder has a volume of 1500, therefor, we will solve for height.
Using our volume equation we plug in all values except h because we're solving for it.
1500=[tex]\pi r^{2} h[/tex]
1500=[tex]\pi 5^{2} h[/tex]
1500=25[tex]\pi[/tex](h)
1500/25[tex]\pi[/tex] = h
60/[tex]\pi[/tex] = h
60/[tex]\pi[/tex] = 19.0985
H is 19ft. (C)

Step-by-step explanation:
The third one down. There are two ways you know this.
1. If you had two boards that where 6 cm and 20 cm and tried to make a triangle with the third side = 27, the two little boards would lie flat on the 27 cm board.

You want to tile a 10 foot square floor with tiles that are twice as long as they are wide. determine how many tiles you need to cover the floor when the tile length is 2 feet
To cover a floor with an area of 10 square foot, 5 tiles is needed.
Area is the amount of space enclosed by a two-dimensional figure.
If the tile is 2 feet long and twice as long as they are wide, suppose that the tile is a rectangle, then the area of each tile will be:
Area of tile = l x w
where l = 2 feet
w = 1 foot
Area of tile = 2feet(1 foot)
Area of tile = 2 ft^2
To determine how many tiles are needed to cover a 10 foot square floor, divide the area of the floor with the area of each tile.
# of tiles = Area of floor/Area of each tile
# of tiles = 10 ft^2/2ft^2
# of tiles = 5

Which ratio is equivalent to the ratio 20 to 35? 5 to 7 7 to 5 8 to 14 14 to 8
Answer: it’s 8 to 14 number c
Step-by-step explanation:
Let me know if I’m wrong
The ratio equivalent to 20 to 35 is 8 to 14.
Option C is the correct answer.
What is a ratio?The ratio shows how many times one value is contained in another value.
Example:
There are 3 apples and 2 oranges in a basket.
The ratio of apples to oranges is 3:2 or 3/2.
We have,
20 to 35
This can be written as,
= 20/35
= 5 x 4 / 5 x 7
= 4/7
Now,
5 to 7 = 5/7
7 to 5 = 7/5
8 to 14 = 8/14 = 4/7
14 to 8 = 14/8 = 7/4
Thus,
20 to 35 is the same as 8 to 14.

Find the equation of the line that passes through the following points. Write the equation in slope-intercept form.
(-4.-8) and (-8, -9)
Answer:
The equation in the slope-intercept form will be:
y = 1/4x - 7
Step-by-step explanation:
Given the points
(-4.-8) (-8, -9)[tex]\mathrm{Slope}=\frac{y_2-y_1}{x_2-x_1}[/tex]
[tex]\left(x_1,\:y_1\right)=\left(-4,\:-8\right),\:\left(x_2,\:y_2\right)=\left(-8,\:-9\right)[/tex]
[tex]m=\frac{-9-\left(-8\right)}{-8-\left(-4\right)}[/tex]
[tex]m=\frac{1}{4}[/tex]
We know that the slope-intercept of line equation is
[tex]y=mx+b[/tex]
where m is the slope and b is the y-intercept
substituting m = 1/4 and the point (-4, -8) to find the y-intercept 'b'
y = mx+b
-8 = 1/4(-4)+b
-8 = -1 + b
b = -8+1
b = -7
so the y-intercept = b = -7
substituting m = 1/4 and b = -7 in the slope-intercept form of line equation
y = mx+b
y = 1/4x + (-7)
y = 1/4x - 7
Thus, the the equation in slope-intercept form will be:
y = 1/4x - 7

Yohanna is conditioning all summer to prepare for her high school's varsity soccer team tryouts. She is incorporating walking planks into her daily workout plan. Every day, she will complete six more walking planks than the day before. If she starts with two walking planks on the first day, how many walking planks will Yohanna do on the 15th day?
Answer: 86
Step-by-step explanation:
Since we want to know the number of walking plans that she will do on the 15th day, we have to use 14 days in our calculations as the first day isn't included.
Therefore, the equation to solve this will be:
= 2 + 6d
where,
d = number of days = 14 days
= 2 + 6d
= 2 + 6(14)
= 2 + 84
= 86
