31. The students are selling wrapping paper to raise money. Each roll of paper rolle for 5%,
Part A
Write m expression that represents the total amount of money, in dollars, the students raise
from selling x rolls of wrapping paper
Part B.
The goal of the students was to raise $600. They sold 6% rolls of paper. By what amount did
the students miss their goal of raising 5600? Show or explain all of your work
Answer:
So The Answer would be 600=1.05x and 600=1.06x for part A and B
Step-by-step explanation:
For Part B If there goal is to raise 600$ then 5% of 600$ = 30$ per roll of wrapping paper;
Part A: 600= 1.05x
The expression 1.05 represents the 5% increase for X wrapping paper sold to the equivalent of 600$
For end of the Question Im unsure what they mean they "missed there goal of raising 5600?.. 5600$ or 560.0$?"

A pizza pan is removed at 9:00 PM from an oven whose temperature is fixed at 425°F in a room that is constant 74°F. After 5 minutes, the pizza pan is at 300 °F
A) at what time is the temperature of the pan 130°F ?
B) determine the time that needs to elapse before the pan is 180°
Answer:
9:11:48 p.m
9.8 minutes
Step-by-step explanation:
We Obtian the slope of the relation :
Slope = Rise / Run
(0, 425) ; (5, 300)
x2 = 0 ; y2 = 425 ; x1 = 5 ; y1 = 300
(425 - 300) / (0 - 5)
125 / - 5
= - 25
The intercept :
y = mx + c
425 = - 25(0) + c
425 = 0 + c
c = 425
The equation becomes :
y = - 25x + 425
Temperature at 130
130 = - 25x + 425
130 - 425 = - 25x
-295 = - 25x
x = 11.8
9:00 + 11.8 = 9:11:48 p.m
B.)
180 = - 25x + 425
180 - 425 = - 25x
-245 = - 25x
x = 9.8 minutes

Which of the following correctly isolates the constant for the polynomial: x2 – 12x + 27
A. x^2 – 12x = 27
B. x^2 - 12x = 36
C. x^2 - 12x = -27
D. x^2 + 27 = 12x
Answer:
x^2 - 12x = -27
Step-by-step explanation:
Here, we want to isolate the constant for the polynomial
To do this, we start by setting the expression to zero
Afterwards, we can bring the constant term over the equal to sign, giving a change in sign value
Mathematically, we have this as;
x^2 - 12x + 27 = 0
x^2 - 12x = -27

"Use the Pyhthagorean Theorem to find the missing side of the right triangle" Please help!
Answer:
9
Step-by-step explanation:
a^2 + b^2 = c^2
a^2 + 40^2 = 41^2
a^2 + 1600 = 1681
a^2 = 1681 - 1600
a^2 = 81
a = 9
At a school, 133 students play at least one sport. This is 35 % of the students at the school. How many students are at the school?
Answer:
380 students
Step-by-step explanation:
133 = 35%
[tex]\frac{133}{35}[/tex] = 1%
3.8 = 1%
3.8 * 100
= 380

hope this helps I'm not sure about number 2 tho
 please help me ahhh im doing 8th grade math with pythagorean theorem
Step-by-step explanation:
The pythagorean theorem is the sum of the two legs squares equal the hypotenuse squared.
The hypotenuse is the longest side so 3.5 is our hypotenuse.
Apply formula to see of true.
[tex] {a}^{2} + {b}^{2} = {c}^{2} [/tex]
[tex] {2.5}^{2} + {3}^{2} = {3.5}^{2} [/tex]
[tex]6.25 + 9 = (3.5 {}^{2}) {?} [/tex]
[tex]15.25 = 12.25 {?}[/tex]
So it isn't a triangle since they aren't equal

what is the equation of the given line ( 1,5) and (3,5)
A.)Y=5
B.)X=3
C.)Y=3
D.)X=1
Answer:
A) y = 5
Step-by-step explanation:
Points: (1, 5) and (3, 5)
Slope:
m=(y2-y1)/(x2-x1)
m=(5-5)/(3-1)
m=0/2
m = 0
Since 0 is the slope, that means there's no slope.
y - y1 = m(x - x1)
y - 5 = 0(x - 1)
y - 5 = 0
y = 5

The sum of two numbers is 57 and the difference is 7. What are the numbers?
Answer:
32 and 25
Step-by-step explanation:
One angle of a triangle measures 95° the other two angles are in a ratio of 7:10 what are the measures of those two angles
Answer:
35 degrees and 50 degrees
Step-by-step explanation:
The sum of all the angles in a triangle must be 180 degrees. So 180 - 95 = 85 leftover for the other two angles. Since we have a ratio of 7:10, we can add that up to get 17 total pieces of that 85-degree angle. 85 / 17 = 5, so each piece is 5 degrees. Therefore, the other two angles are 7*5 = 35 degrees and 10*5 = 50 degrees.
The volume of a cylinder is 980 in cubed.
The height of the cylinder is 20 in. What is the radius of the cylinder?
Express your answer to the nearest hundredth.
9514 1404 393
Answer:
3.95 in
Step-by-step explanation:
The volume is given by ...
V = πr²h
Solving for radius, we get ...
r = √(V/(πh))
For the given numbers, the radius is ...
r = √(980 in³/(π·20 in)) = 7/√π in ≈ 3.95 in
The radius of the cylinder is about 3.95 inches.

I don't understand this my teacher is not texting me back
Answer:
Please find below. Fill in the table with the values of y given below.
Step-by-step explanation:
For question 5, you should substitute the different values of x into the equation y =x^2 +4
So, when
x = -3, y = (-3)^2 +4 = 9+4 = 13
x = -2, y = (-2)^2 +4 = 4+4 = 8
x = -1, y = (-1)^2 + 4 = 1+4 = 5
x = 0, y = 0^2 + 4 = 4
x = 1, y = 1^2 +4 = 1+4 = 5
x = 2, y = 2^2 +4 = 8
x = 3, y = 3^2 + 4 = 13
x = 4, y = 4^2 + 4 = 20
For question 6, you need to find the nth term or a formula of y in terms of x.
For this, find the common difference between each of the consecutive values of y.
This is 5
So, the start if our equation is going to be ‘y = 5x’
Now, to find the ‘+c’ part, can be calculated by substituting the value of y when x = 1 into the y = 5x
So,
y = 5x + c
13 = 5 + c
Rearrange the find that c = 8
Therefore, the nth term formula = 5x + 8
Hope this helps
