The circle graph shows the results of a survey. Of those surveyed, 80 said yes. About how many people were surveyed?
Answers
Answer:
134 people
Step-by-step explanation:
80 / .6 = 133.333
Answer:
134 people
Step-by-step explanation:
we can use cross multiplication to solve this problem:
we know that 60% is 80 people and 40% is x people (we put x because we don't know the exact number of how many people yet)
now we set it up:
[tex]\frac{80}{60}[/tex] = [tex]\frac{x}{40}[/tex]
= 60x = 3200
= x = 53.33333
now we add the two numbers of people up:
53.33333 + 80 = 133.3333
since it is a decimal, it would be safer to assume that there are 134 people

A cylindrical barrel holds 10,164 cubic inches of oil (44 gallons). If the cylindrical barrel is 23 inches in diameter, what is the approximate height of the barrel?
a. 21 inches
b. 24 inches
c. 60 inches
d.141 inches
Answers
Answer:
I believe it’s A.21
Step-by-step explanation:
HOPE THIS HELPS YOU
The approximate height of the barrel is 22.9 inches. They are also important in mathematics and engineering, as they are used to model and solve problems in various fields, such as calculus, geometry, physics, and fluid mechanics.
What is Cylinder?A cylinder is a three-dimensional geometric shape that consists of two parallel, congruent circular bases connected by a curved surface. The curved surface is composed of a set of parallel lines that connect the two circular bases.
here, we have,
The cylinder can be described by several measurements, including its height (the distance between the two circular bases), its radius (the distance from the center of one circular base to its edge), and its diameter (the distance across the cylinder at its widest point, passing through the center of the circular bases).
We can use the formula for the volume of a cylinder to find the height of the barrel:
V = πr²h
We are given that the volume of the oil is 10,164 cubic inches and the diameter (which is twice the radius) is 23 inches.
r = 23/2 = 11.5 inches
10,164 = π(11.5)²h
Solving for h, we get:
h = 10,164 / (π(11.5)²) ≈ 22.9 inches
So the approximate height of the barrel is 22.9 inches.

If the diameter is 26 inches, what is the radius
Answers
Answer:
13 inches
Step-by-step explanation:
In any circle, the radius is always half of the diameter.
So, the diameter can be found by multiplying the radius by 2, and the radius can be found by dividing the diameter by 2.
Since the diameter is 26 inches, we can divide this by 2 to get the radius
26/2
= 13
The radius is 13 inches
Answer:
[tex] \bf \huge13[/tex]
Step-by-step explanation:
Given that : the diameter is 26 inches.to find :what is radius .formulas used :radius = diameter / 2explanation :we know that,
finding the radius
⟼ diameter = 26 inches
⟼ radius = diameter / 2
⟼ radius = 26 / 2 inches
⟼ radius = 13 / 1 inches
⟼ radius = 13 inches.
∴ radius is 13 inches .

(She has 18 students and 6 students wrote 4 pages)
Answers
Answer:
33 1/3%
Step-by-step explanation:
Explained in question comments :)
The percent of Mrs. Vega's class who wrote a 4 page book report is 33 1/3 %.
What is Percentage?Percentage is defined as the parts of a number per fraction of 100. We have to divide a number with it's whole and then multiply with 100 to calculate the percentage of any number.
Percentage is usually denoted by the symbol '%'.
Given a dot plot which shows the number of pages written by the students in her first-period class.
Total number of students in Mrs. Vega's class = 18
[Total number of students is the number of dots in the dot plot]
Number of students who wrote 4 pages = number of dots above 4 = 6
Percentage of students who wrote 4 pages = 6/18
= 0.333
= 33.3%
= 33 1/3 %
Hence the required percent is 33 1/3 %.

Answers
Answer: I think the answer might be 9.28.
Step-by-step explanation:
I was also confused with this question so I might be wrong.
Using the information provided above I was able to conclude that two possible equations you can form is A+B=17.18, where there is only 1 stock from company A and 1 stock from company B. The other equation is 52A+65B=1,014 since this is the total amount she spend on the stocks.
You can use Desmos to graph both of the equations or solve it by hand. If solving it by hand chose which method you wanna use wether it is elimination or substitution. (I would explain the process, but I am lazy)

His friend Asia works for the same radio station but she receives a salary only, which is $ 1 , 275 $1,275 per week. How many packages does Nic need to sell in a week to earn as much as Asia?
Answers
Answer:
15 Packages
Step-by-step explanation:
Let number of packages = x
For Nic
Nic sells advertising packages for a radio station. The company pays him $ 150 per week and they also pay him $ 75 for every package he sells.
Equation =
150 + 75x
His friend Asia works for the same radio station but she receives a salary only, which is $ 1 , 275per week.
We solve by equating
150 + 75x = 1275
75x = 1275 - 150
75x = 1125
x = 1125/75
x = 15 Packages
