Answer:
1: 4.5 cups of flour
2: 12.125 ft of rope
3: 68.5 inches above ground
4: 21.3333..... ounces of water
5: 2.5 ft below the surface
Step-by-step explanation:
1: 8.25-3.75=4.5
2: 15.5-3.375=12.125
3: 92.75-24.25=68.5

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]

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

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
ASAP HELP! Which angles are pairs of corresponding angles? Check all that apply.

Angle1 and Angle3
Angle2 and Angle14
Angle1 and Angle6
Angle3 and Angle7
Angle8 and Angle9
Angle5 and Angle12
Answer:
angle 2 and angle 14 angle 3 and angle 7Step-by-step explanation:
Assuming angles are numbered clockwise at each intersection before moving to the next intersection, corresponding angles will differ in their numbers by a factor of 4.
Among the offered choices, the differences of angle numbers are ...
2, 12, 5, 4, 1, 7
Of those pairs listed, angles 2 and 14, and angles 3 and 7 are corresponding angles.

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]

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.

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! :)
