Answer:
Step-by-step explanation:
-39 = 18 + 4m
4m + 18 = -39
Subtract 18 from both sides
4m = -39 - 18
4m = -57
Divide both sides by 4
m = -57/4

Look at the picture of a scaffold used to support construction workers. The height of the scaffold can be changed by adjusting two slanting rods, one of which, labeled PR, is shown: A support structure is shown in which a right triangle PQR is formed with the right angle at Q. The length of PQ is shown as 14 feet, and the length of QR is shown as 6 feet.. Part A: What is the approximate length of rod PR? Round your answer to the nearest hundredth. Explain how you found your answer, stating the theorem you used. Show all your work. (5 points) Part B: The length of rod PR is adjusted to 16 feet. If width PQ remains the same, what is the approximate new height QR of the scaffold? Round your answer to the nearest hundredth. Show all your work. (5 points)

Let fat be the explanatory variable and calories be the response variable; which scenario best describes ŷ = 121 + 1.42x?
The amount of calories in a cheeseburger increases by 1.42 for every one gram of fat. The calorie amount estimated by this model is 121 if there are zero grams of fat.
The amount of calories in a cheeseburger increases by 121 for every one gram of fat. The calorie amount estimated by this model is 1.42 if there are zero grams of fat.
The amount of fat in a cheeseburger increases by 121 grams for every one calorie.
The fat amount estimated by this model is 1.42 grams if there are zero calories.
The amount of fat in a cheeseburger increases by 1.42 grams for every one calorie.
The fat amount estimated by this model is 121 grams if there are zero calories.
The amount of calories in a cheeseburger increases by 1.42 when there are zero grams of fat.
The calorie amount estimated by this model is 121 if there is one gram of fat.
Using linear function concepts, it is found that the correct option is:
The amount of calories in a cheeseburger increases by 1.42 for every one gram of fat. The calorie amount estimated by this model is 121 if there are zero grams of fat.
A linear function is modeled by:
[tex]y = mx + b[/tex]
In which:
m is the slope, which represents by how much y changes when x changes by 1.b is the y-intercept, which is the value of y when x = 0.In this problem:
The explanatory variable fat is the input.The response variable calories is the output.The equation is:
[tex]y = 121 + 1.42x[/tex]
The slope is of 1.42, which means that the amount of calories increases by 1.42 when the amount of fat increases by 1 gram.The y-intercept is of 121, which means that if there are 0 grams of fat, there will be 121 calories.Thus, the correct option is:
The amount of calories in a cheeseburger increases by 1.42 for every one gram of fat. The calorie amount estimated by this model is 121 if there are zero grams of fat.

Last year, 3,270 athletes finished a marathon in Lancaster. This year, there were 2,616 athletes finishing. What is the percent of decrease in the number of finishers? %
Answer:
20% decrease
Step-by-step explanation:
2516/3270 = 0.8 or 80%
This means 80% percent of people showed up again from last year
100-80 = 20
So 20% decrease

Step-by-step explanation:
well, if they're sixty tickets and each cost approx. $90, which means it's 60 x 90, and that gets to 5,400.
What is the answer to 2 and 3?
Answer:
p = -10
shortest side (a) = 5
longest side (b) = 12
Step-by-step explanation:
QUESTION 2: Solve for p by isolating the variable.
3/4 p - 1/4 p + 3 = -2 ----- subtract 3 from both sides
3/4 p - 1/4 p = -5
2/4 p = -5 ----- simplify 2/4
1/2 p = -5 ------ multiply 2 on both sides
p = -10
QUESTION 3:
Perimeter of a triangle = a + b + c
a = x
b = 3x - 3
c = 2x
x + 2x + 3x - 3 = 27 cm ------ combine like terms
6x - 3 = 27 ----- add 3 on both sides
6x = 30
x =5 ------- substitute 5 everywhere you see "x" for the side values
side a = x = 5
side b = 3x - 3 = 3(5) - 3 = 12
side c = 2x = 2(5) = 10
shortest side (a) = 5
longest side (b) = 12
Answer:
Answer to question 2:
[tex]\frac{\left(3\right)}{\left(4\right)}p-\frac{\left(1\right)}{\left(4\right)}p+3=-2\quad :\quad p= ?[/tex]
[tex]\frac{\left(3\right)}{\left(4\right)}p-\frac{\left(1\right)}{\left(4\right)}p+3=-2[/tex]

Answer to question 3
Measure of the shortest side is 5 cm
Measure of the longest side is 12 cm
Given:
Perimeter of ∆ = 27 cm
Side lengths of ∆: x, 2x, and 3x - 3
Required:
Measure of the shortest side and measure of the longest side.
Sum of all sides of the ∆ = Perimeter
Solve for x
Collect like terms
Add 3 to both sides
Divide both sides by 6
Length of each side of the ∆:
x = 5 cm
2x = 2(5) = 10 cm
3x - 3 = 3(5) - 3 = 15 - 3 = 12 cm
Measure of the shortest side is 5 cm
Measure of the longest side is 12 cm
Step-by-step explanation:

ive answered a and b but struggling to answer c. how do you work it out?
Answer:
-2, 1.5
Step-by-step explanation:
(y1 + y2)/2 = y midpoint formula
so, (-1 + 4) = 3
3 / 2 = 1.5
y = 1.5
Step-by-step explanation:
To find the midpoint:
Use the formula;
d = (x2 + x1)/2, (y2 + y1)/2 where x2 = -2, x1 = -2, y1 = -1, y2 = 4
Substitute the values into the equation above. This gives;
d = (-2 + -2)/2, (4 + -1)/2
= (-4/2), (3/2)
=(-2, 1.5) <<<<<<< ✓ Ans

Find the surface area of the square pyramid. Round your answer to the nearest hundredth.
A. 175.42
B. 176.42
C. 185.42
D. 192.42
Answer:
175.42
Step-by-step explanation:
surface area of square pyramid is given by:
Area= s^2 + 2(s)(l)
where s is the base and l is the slant height
in given problem, slant height l is not given, so by using Pythagoras theorem finding l:
c^2= a^2 + b^2
= 8^2 + 4^2
= 48.49
c = 6.96348
Now putting values of s=8 and l= 6.96 in first formula
Area= 8^2 + 2(8)(6.96)
= 64 + 111.41
= 175.42

Answer:
x • (x^3 - 3x^2y + 3xy^2 + 7y^3)
Step-by-step explanation:
(8x • (y^3)) + x • (x - y)^3
2^3xy^3 + x • (x - y)^3
Evaluate : (x-y)^3 = x^3-3x^2y+3xy^2-y^3
Pull out like factors :
x^4 - 3x^3y + 3x^2y^2 + 7xy^3 =
x • (x^3 - 3x^2y + 3xy^2 + 7y^3)
x^3 - 3x^2y + 3xy^2 + 7y^3 is not a perfect cube

Kyle, Meg & Dan share some money in
the ratio 3:2:7
What fraction of the money does Meg get?
Answer: 1/5 of the money
Step-by-step explanation:
The ratio shows that Kyle gets 3 parts of the money, Meg gets 2 parts of the money, and Dan gets 7 parts of the money. Simple addition lets us know there are 10 parts of the money, and because Meg got 2 of them, she has 2/10ths of the money, or 1/5.
