Help I’m failing math
Step-by-step explanation:
the answer is 72.70 cents
Answer: See explanation
Step-by-step explanation:
Markup is 39% of the cost.
Markup is what is added to the price to get the retail price.
39% × 72.72
0.39 × 72.72 = 28.3608
28.3608 ≈ 28. 36
Markup ≈ $28.36
Retail price is the price you get after you add the markup to the original price.
Retail price: Cost + Markup
Retail price: $72.72 + $28.36
Retail price = $101.08

Answer:
(-5, -3)
Step-by-step explanation:
To graph the two equations, you can look at two things, the slope and the y-intercept.
The two equations are in slope-intercept form, y= mx + b. m is the slope and b is the y-intercept. The slope is rise/run and the y-intercept is where the line crosses the y-axis.
In the first equation, the slope is -1 and the y-intercept is -8. So, to graph you would start at (0, 8) and move up one unit and then left one unit to get the next point.
For the second equation, the slope is 2/5 and the y-intercept is -1. So, to graph you would do the same thing. Start at (0, -1) and then go up 2 units and right 5 units to get the next point.
I've attached a graph below if you need it.

Answer:
The answer is:

A certain drug is made from only 2 ingredients: compound A and compound B. There are 4 milliliters of compound A used for every 5 milliliters of compound B. If a chemist wants to make 666 milliliters of the drug, how many milliliters of compound B are needed?
Answer:
370 millimeters of compound B is needed for 666 millimeters of solution.
Step-by-step explanation:
Given that:
4 millimeters of compound A are used for every 5 millimeters of compound B.
The scientist wants to make 666 millimeters of solution.
Let,
x be the multiplier number of the compounds in the solution.
Then,
4x + 5x = 666
9x = 666
Dividing both sides by 9
[tex]\frac{9x}{9}=\frac{666}{9}\\x=74[/tex]
Millimeters of compound B = 5x = 5(74) = 370 millimeters
Hence,
370 millimeters of compound B is needed for 666 millimeters of solution.

An architect creates a scale model of a building with a scale of 3 inches =11 feet of the actual width of the building is 121 feet what is the width of the scale model
Answer:
The width of the scale model is 33 inches.
Step-by-step explanation:
This question is solved making a relation with the scale model.
In the scale, 3 inches are worth 11 real feet.
The actual width of the building is 121 feet, so we find it's scale by a rule of three.
3 inches - 11 feet
x inches - 121 feet
[tex]11x = 121*3[/tex]
Simplifying by 3, both sides
[tex]x = 11*3 = 33[/tex]
The width of the scale model is 33 inches.

Answer: I learned about these a few years ago in math, and I hated it and sucked at it and it was awful, but ANYWAY, I think the answer is A, angle side angle
Step-by-step explanation: I think the answer is A because:
Angle-side-angle (asa) is when two angles and a side are the same on two triangles, they are congruent.
Angle-angle-side (aas) is when two sides and an angle are the same on two triangles, they are congruent.
Side-side-side (sss) is when all the sides of two triangles are the same, they are congruent.
Side-angle-side (sas) is when two sides and an angle are the same on two triangles, they are congruent.
So Angle side angle is the only one that makes sense. But again, I sucked at this when I was learning it, so I could be totally wrong. I'm pretty sure I'm right though. If I am, would you mind marking branilest? :)

Darren is on a super efficient diet. He started with 210 pounds 2 months ago and he now weighs 150 pounds . Find his percent of decrease.
Answer:
29%
Step-by-step explanation:
210-150/210 = 60/210 or 6/21
Now we have to find the percent out of 100 so we have to find out 100/21 to see what we have to multiply by to get to 100 so we can do the same with the 2 (numerator) so 1000/21= 4 16/21
then we have to multiply the 6 by 4 16/21 which is about 29%
A variable needs to be eliminated to solve the system of equations below. Choose the
correct first step.
7x +y = 33
-7x + 6y = -47
Answer:
x=5 and y=-2
Step-by-step explanation:
The given system of equations are :
7x +y = 33 ....(1)
-7x + 6y = -47 ....(2)
We need to find the solution of the given equations.
Adding equation (1) and (2) we get :
7x +y + (-7x) +6y = 33+(-47)
7y = -14
y = -2
Put the value of y in equation (1).
7x +(-2) = 33
7x-2=33
7x=33+2
7x = 35
x = 5
Hence, the solution of the above equations are x=5 and y=-2
graph the solution on the number line |x-3| <5
Answer:
-2<x<8
see below for graph
Step-by-step explanation:
First, we need to solve the inequality.
Inequality: |x-3|<5
Split into two equations:
x-3<5
x-3>-5 (notice how the sign is flipped when we make the number negative)
let's start with x-3<5
add 3 to both sides
x<8
now
x-3>-5
add 3 to both sides
x>-2
The graph is below
the intersection is the solution.
Notice how I made the maroon line go to the right- which shows that it's greater than (for x>-2) and the silver line go to the left, which shows that it's less than (for x<8)
the equation is -2<x<8

b. Describe the scales you could use on the x and y axes of a coordinate grid that would show all the distances and weights in the table.
distance (cm) weight (newtons)
20 28

Answer:
55= 39 2/7
Step-by-step explanation:
Answer:
See below
Step-by-step explanation:
As per the first row of proportional relationship, the proportion is:
y = kx28 = k*20k = 28/20 = 1.4The function is therefore:
y = 1.4xa) Table is filled in below:
distance (cm) | weight (newtons)
20 | 28
55 | 55*1.4 = 77
140/1.4 = 100 | 140
1 | 1*1.4 = 1.4
---------------------------------------------------------------
b) The scale should consider the coefficient 1.4, therefore x- axis will have a scale of 100 with intervals of 1 cm and y- axis will have a scale of 140 with intervals of 1.4 newtons

Answer:
y = 103
y = 180 - 77 = 103
Step-by-step explanation:
........
Answer:
103
Step-by-step explanation:
All we have to do is subtract the measure of the line which is 180 by 77 to get the measure of < y. Since they are adjacent to each other this concept will work but if they weren't it would be a little different.
[tex]y+77=180\\y=130[/tex]
So the measure of < y is 130°
