Mia is helping her glee club raise money to fund a field trip. The glee club secided to sell pencils, which come in boxes of 100. Each pencil sells for $25. Write an equation using b for boxes and m for total money made answer
Answer:
m = 2500b
Step-by-step explanation:
As instructed,
let b = number of boxes sold
let m = total money made.
The total money made, is a function of the number of boxes sold.
Let me break this down:
There are 100 pencils in a box;
if they sold only one box, they will get 100 X $25 = $2500;
if they sold two boxes, they will get 200 X $25 = $5000;
if they sold three boxes, they will get 300 X $25 = $7500;
Following the trend, we can deduce that money made, m = (number of boxes sold X 100 ) X $25
representing this using the variables we were given, we have
m = 100b X 25
hence
m = 2500b

Convert the angle 1 radian to degrees, rounding to the nearest 10th.
Answer:
57
Step-by-step explanation:
57 rad×180/pie
ans:57.296 round to 10th
equals 57
The value of the angle 1 radian to a degree is 57.25.
What is a radian?The standard unit of angular measurement used in many branches of mathematics is the radian, indicated by the symbol rad. It is the unit of angle in the International System of Units. Previously, the unit was a SI supplementary unit.
The one radian is equal to the 180 divided by π. So the value of one radian in degree will be calculated as,
1 Radian = 180 / π
1 Radian = 57.25°
Therefore, the value of the one radian in degree is equal to 57.25.

A two feet tall wheelchair ramp is placed from a sidewalk to the main door of a library. If the length of the ramp is 16 feet, how far away is the bottom of the ramp from the sidewalk?
Answer:
Distance from bottom to side walk = 15.87 feet (Approx.)
Step-by-step explanation:
Given:
Height of ramp = 2 feet
Length of ramp = 16 feet
Find:
Distance from bottom to side walk
Computation:
Height of ramp (perpendicular) = 2 feet
Length of ramp (hypotenuse) = 16 feet
Distance from bottom to side walk (Base)
Base = √hypotenuse²- perpendicular²
Base = √16²- 2²
Base = √256 - 4
Base = √252
Base = 15.874
Distance from bottom to side walk = 15.87 feet (Approx.)

The dimensions of a rectangular pool are 26.5 feet by 14 feet. The
depth of the water when full is 5 feet. Each cubic foot contains 7.48
gallons of water. How many gallons of water, to the nearest tenth, are
needed to fill the pool to 80% capacity?
Answer:
29.9 gallons
80% percent of 5 is 4.
So, we multiply 7.48 by 4, which gives us 29.9 gallons.

A study was commissioned to find the mean weight of the residents in a certain town. The study examined a random sample of 132 residents and found the mean weight to be 162 pounds with a standard deviation of 35 pounds. At the 95% confidence level, find the margin of error for the mean, rounding to the nearest tenth
Answer: 6.1
We are 95% confident that the true mean weight of the population is within 6.1 pounds of the sample mean 162.
At the 95% confidence interval, the margin of error for the mean is 6.1 pounds
What is margin error?The margin of error is "a statistic expressing the amount of random sampling error in the results of a survey".
According to the question,
Number of random samples (n) = 132 residents
Mean of weight of random samples (x⁻)= 162
Standard deviation of random samples (σ)= 35 pounds
In order to find at the 95% confidence interval, the margin of error for the mean.
Margin error = z (σ/√n)
The critical region 95% confidence interval under normal curve is 1.96.
= 1.96 (35/√132)
=1.96(35/11.48)
=1.96(3.0488)
= 5.9708636 ≈ 6.1 pounds
Hence, at the 95% confidence interval, the margin of error for the mean is 6.1 pounds.

The tip of a windshield wiper travels a distance of 31 inches in one 90 revolution. What is the
length of the windshield wiper to the nearest inch?
F 10 in.
G 15 in.
H 20 in.
J 39 in.
PLEASE HELP!!1
Answer:
Option F, 10 inches.
Step-by-step explanation:
For a circle of radius R, the perimeter is:
P = 2*pi*R
such that pi = 3.14
If we have a section of that circle defined by an angle θ, the length of the arc is:
A = (θ/360°)*P = (θ/360°)* 2*pi*R
In this case, we have a circle whose radius is defined by the length of the windshield wiper.
We also know that in one 90° revolution (so it travels the length of the arc of 90° two times) the tip travels a distance of 31 in.
Then:
A = 2*[(90°/360°)*2*3.14*R] = 31in
We need to solve this for R.
R = 31in/( 2*(90°/360°)*2*3.14) = 9.8in
We can round this to the next whole number:
R = 10in
The correct option is F.

Explain some of the opinions on women being on bicycles back then.
Answer:
To women, it was a steed upon which they rode into a new world. All this triggered a backlash from many (male) doctors and onlookers, who cited all sorts of reasons to dissuade women from riding bikes. It would lead to not only bicycle face, but also exhaustion, insomnia, heart palpitations, headaches, and depression. During the late 19th and early 20th centuries, women began to escape some of their restrictions by riding bycicles. Despite strong opposition from men, women cycled on, and the bicycle became an instrument of change that subverted the status quo and became a powerful symbol of women's emancipation.
