A cylindrical of oatmeal canister has a diameter of 4 inches and a height of 10 inches. The manufacturing company wants to package the oatmeal in square containers to cut back on wasted storage space. If the new carton has a square base with 4 inch sides, what is the minimum height it must have, to the nearest 1/4 inch, to hold the same volume of oatmeal? Use 3.14 for the value of π.
Step-by-step explanation:
Volume of cylinder = pi r^2 h
Volume of square container = s x s x h
they need to be equal
pi r^2 h = s^2 h
pi (2)^2 * 10 = 4^2 h (diameter = 4 then radius = 2)
40pi / 16 = h = 7.9 in = ~ 8 in to the nearest 1/4 inch

Answer:
123
Step-by-step explanation:
the two triangles are equiangular.
VZ/ZY = VW/WX
13.5/27.5 = VW/36
VW= 16.5*36/27.5 = 21.6
WZ/XY= 3/5
WZ:XY= 3:5
Pythagoras THEROM
44^2 + XY^2= 57.6^2
XY= 37.17

Bryan randomly asked several students which type of animal they had at home as a pet. The results are in the pie chart below.
a. What percent of the students had dogs?
b. What percent of the students had birds?
c. How many total students did Bryan interview?
Answer:
60% of the students have dogs
10% of the students have birds
Bryan interviewed 200 students
Step-by-step explanation:
a.3/5 = 60%
b.60% + 30% = 90%
100% - 90% = 10%
c. 20 x 10 = 200
Answer: 60%, 10%, 200 students.
Step-by-step explanation:
Let's start with turning all of the values into percentages.
3/5 of the students said dogs. As a percentage, 3/5 is equal to 60%.
We now have two percentages, the amount of cats and the amount of dogs. 30%+60%=90%. So that leaves 10%, and that 10 percent is the 20 students who had birds.
If 20=10%, all we have to do is multiply 20 ten times to get to 100%. 20x10=200.
There were 200 students interviewed.

The answer would be 3 miles on each of the six days
Answer:
In a week we have 7 days.
On the first day, Clare runs 4 miles.
On the other six days, she runs the same distance, let's call it D.
In total, she runs 22 miles.
Then:
4mi + 6*D = 22 mi
6*D = 22mi - 4mi = 18mi
D = 18mi/6 = 3mi.
Then the other 6 days, Clare runs 3 miles

Answer:
1017 cm³
Step-by-step explanation:
To find the volume of this figure we will first need to divide it into 2 sections. First, we will find the volume of the semicircle on top then the cone at the bottom!
1) Semicircle
The simplest way of doing this is to find the volume as if it was a circle and then divide that result by 2! ([tex]\frac{4}{3}[/tex]πr³)
[tex]\frac{4}{3}[/tex] × 3.14 × 6³ = 904.32904.32 ÷ 2 = 452.162) Cone
To find the volume of the cone we need to apply the equation πr²[tex]\frac{h}{3}[/tex] (where h = height)
3.14 × 6² × [tex]\frac{15}{3}[/tex] = 565.23) Add
452.16 + 565.2 = 1017.361017 rounding to the nearest whole number!Hope this helps, have a lovely day! :)

Answer:
There are 55 large boxes
and 70 small boxes.
Step-by-step explanation:
Let's assume that the number of large boxes is x, and the number of small boxes is y. We then can use how many pounds each box weighs to form a system of equations.
System:
[tex]50x+25y=4500\\x+y=125[/tex]
Step 1: Solve for a variable
[tex]x+y=125[/tex] is also [tex]y=-x+125[/tex]
Step 2: Substitute
[tex]50x+25(-x+125)=4500[/tex]
Step 3: Simplify
[tex]50x+-25x+3125=4500\\25x=1375\\x=55[/tex]
Step 4: Solve for y
[tex]y=-55+125\\y=70[/tex]

The radius of a cylinder is (3x-2cm). The height of the cylinder is (x+3cm).
What is the surface area of the cylinder?
Use the formula A=2\pi r^(2)+2\pi rh.
Answer:
[tex](24\pi x^2-10\pi x-4\pi)[/tex] square centimeters
Explanation:
Let
[tex]r=\text{radius of the cylinder}=3x-2 < br/ >[/tex]
[tex]h=\text{height of the cylinder}=x+3[/tex]
Then the surface area of the cylinder is given by
[tex]A=2\pi r^2+2\pi rh[/tex]
[tex]=2\pi r(r+h)[/tex]
[tex]=2\pi (3x-2)((3x-2)+(x+3))[/tex]
[tex]=2\pi (3x-2)(4x+1)[/tex]
[tex]=2\pi(12x^2-5x-2)[/tex]
[tex]\boxed{A=(24\pi x^2-10\pi x-4\pi )cm^2}[/tex]

bryce has a board that is 8[tex]\frac{5}{16}[/tex] feet long .
He cuts off 2[tex]\frac{3}{8}[/tex]
feet to use for a project . what is the length of the board that is left ?
★ . what is the original length of the board ?
★ . what is the length that was cut off ?
★ . write and solve an equation .
★ . the length of the board that is left is ?
Answer:
The original length of the board is 8 feet.
The length that was cut off is 2 feet.
One possible equation we can use is: x = 8 - 2, where x represents the length of the board that is left. Solving for x, we get x = 6 feet.
The length of the board that is left is 6 feet.
Step-by-step explanation:
We are given that the board was originally 8 feet long. Bryce cuts off 2 feet from the board to use for a project. Therefore, the length of the board that is left is 8 - 2 = 6 feet.
To solve this problem algebraically, we can set up an equation where x represents the length of the board that is left. We know that the original length of the board is 8 feet, and 2 feet was cut off, so we can write:
x = 8 - 2
Simplifying this equation gives us:
x = 6
Therefore, the length of the board that is left is 6 feet.

Graph m(x) on a coordinate plane to determine whether or not the function represents a direct variation. In complete sentences, describe your conclusion and reasoning. Include your graph in your answer.
Answer:
m(x) = 1.5x . . . . direct variation
Step-by-step explanation:
You want to know if the function m(x) represents direct variation, given a table of values.
Direct variationAn equation for direct variation is ...
y = kx
where k is a constant that can be found as the ratio of any (x, y) pair:
k = y/x
k = -1.5/-1 = 1.5/1 = 3/2 = 6/4 = 1.5
The ratios are constant, hence m(x) is direct variation with a constant of variation of 1.5.
GraphThe graph of direct variation is a straight line through the origin. The given points lie on such a line.
