The volume of a cylindrical container is 157 cubic inches. The height of
the container is 2 inches. Find the radius of the container. Round your
answer to the nearest whole number?
Answer:
r = 7 inStep-by-step explanation:
h = 2 in , V = 157 in³
V = π r² × h
157 = π r² × 2
157 = 2π × r²
[tex]r^2=\dfrac{157}{2\pi}\\\\r=\sqrt{\dfrac{157}{2\pi}}\ in=7.0692...\ in\approx7\ in[/tex]

An Ice Cream Factory makes 3:1 tubs of ice cream to boxes of ice cream bars. If the factory makes 165 tubs of ice cream in a day, how many boxes of ice cream bars were made?
Answer:
55 boxes of ice cream
Step-by-step explanation:
Tubs of ice cream : boxes of ice cream = 3 : 1
If the factory makes 165 tubs of ice cream in a day, how many boxes of ice cream bars were made?
Boxes of ice cream made in a day = x
Tubs of ice cream : boxes of ice cream = 165 : x
Equate both ratios to find x
3 : 1 = 165 : x
3/1 = 165/x
Cross product
3 * x = 1 * 165
3x = 165
x = 165/3
x = 55
Boxes of ice cream made in a day = 55

Calculate the circumference (C) of the wheel
C = πd (d is the diameter )
= 3.14 × 8 = 25.12 cm
Now divide the distance travelled by the circumference.
times rotated = 12560 ÷ 25.12 ≈ 500
----------------------------------------------------------------
(2)
The area (A) of a circle is calculated as
A = πr² ( r is the radius )
Find r by using the circumference (C)
2πr = 50.24 ( divide both sides by 2π )
r = 50.24 ÷ 6.28 = 8 , then
A = 3.14 × 8² = 3.14 × 64 ≈ 200.96 ft² ( student 3 )
-----------------------------------------------------------------
(3)
C = πd = 3.14 × 30 = 94.2 ≈ 94 m

Write an equation that represents the line?
Answer:
An equation that represents the line is:
y = 3/4x - 9/2
Step-by-step explanation:
The slope-intercept form of the line equation
[tex]y = mx+b[/tex]
where
m is the slopeb is the y-interceptGiven the attached graph of a line.
Taking two points from the line, such as
(2, -3)(6, 0)Determining the slope between (2, -3) and (0, 6)
[tex]\left(x_1,\:y_1\right)=\left(2,\:-3\right),\:\left(x_2,\:y_2\right)=\left(6,\:0\right)[/tex]
[tex]m=\frac{0-\left(-3\right)}{6-2}[/tex]
refine
[tex]m=\frac{3}{4}[/tex]
substituting m = 3/4 and the point (2, -3) in the slope-intercept form of the line equation
y = mx + b
[tex]\left(-3\right)=\frac{3}{4}\left(2\right)+b[/tex]
[tex]\frac{3}{2}+b=-3[/tex]
subtract 3/2 from both sides
[tex]\frac{3}{2}+b-\frac{3}{2}=-3-\frac{3}{2}[/tex]
[tex]b=-\frac{9}{2}[/tex]
now substituting b = -9/2 and m = 3/4 in the slope-intercept form of the line equation
y = mx + b
y = 3/4x + (-9/2)
Therefore, an equation that represents the line is:
y = 3/4x - 9/2
Nellie's Tea Shop has caffeinated tea and decaffeinated tea. During the lunchtime rush, the tea shop served 40 teas in all, 70% of which were caffeinated. How many caffeinated teas did the tea shop serve?
Answer: 28 caffeinated teas
Step-by-step explanation:
The tea shop served 40 teas in all.
70% of this 40 were caffeinated.
The actual number that was caffeinated is therefore:
= Number of teas served * Caffeinated percentage
= 40 * 70%
= 28 caffeinated teas

Answer:
Michael is incorrect.
if we take the steps Michael says and move the ABCDE up 8 and right 10, not all of the points line up.
Step by step explanation:
In order to get the shapes to line up, we need to flip (reflect) ABCDE onto the 2nd Quadrant, then we can move (translate) it to the right by 10.

What is the probability that a student selected at random takes math or drama? (round answer to 3 decimal places)
Distribution table for the question is attached below :
Answer:
0.533
Step-by-step explanation:
Let :
M = math
D = Drama
Probability that a randomly chosen student takes math or drama ; P(M u D)
Recall:
P(A u B) = p(A) + p(B) - p(A n B)
P(M u D) = p(M) + p(D) - p(M n D)
Probability = required outcome / Total possible outcomes
From the table :
P(M) = 119 / 302
P(D) = 67 / 302
P(M n D) = 25 / 302
Therefore,
P(M u D) = 119/302 + 67/302 - 25/302
P(M u D) = (119 + 67 - 25) / 302
P(M u D) = 161 / 302
P(M u D) = 0.5331125
P(M u D) = 0.533 ( 3 decimal places)

The solution to the product of the two figure is 1 trillion
The product of two given figuresTo know how much the product of this figures is
1000000 x 1000000 = 1 trillion
To calculate this, we can multiply 1,000,000 (1 million) by itself:
1,000,000 x 1,000,000 = 1,000,000,000,000
So 1000000 x 1000000 is equal to 1 trillion (1,000,000,000,000).
1 trillion is a very large and significant number that is often used to describe quantities on a global or macroeconomic scale.

Choose the correct comparison for the numbers below.
0.85, 3/4, 91%
a. 3/4 > 0.85 > 91%
c. 91% > 3/4 > 0.85
d. 0.85 < 3/4 < 91%
Answer:
A
Step-by-step explanation:
In order to compare all three numbers, you must change them all to have the same form, either all decimal form, all fraction, or all percentages.
The easiest ways to compare are decimal and percentage, as they're practically the same thing. For simplicities sake, though, let's turn all the numbers into decimal.
Since 0.85 is already in decimal form, leave it as it is.
3/4 can be turned into a decimal by putting it into a calculator, but intuitively you should know that it's 0.75. If you don't know a fraction intuitively, you just need to make the fraction into a multiple of denominator 100 and take the numerator. For example:
[tex]\frac{3}{4} * \frac{25}{25} = \frac{75}{100}[/tex]
Numerator is 75.0, now simply move the decimal place up to to get the decimal form 0.75.
91% can be changed into a decimal by moving the decimal place left 2 places. 91.0% turns into 0.91.
Now that you can see the numbers, just rearrange them from least to greatest
0.75<0.85<0.91

mZ1 +mZ2 = 90° and if mZ1 +mZ3 = 90°, then 22 =23. What is
the error in Jayden's reasoning?
Answer:
The congruent supplements theorem states that 2 angles are supplementary if they add up to 180 degrees, not 90 degrees.
He should have stated the complimentary theorem instead.
Step-by-step explanation:
The correct statement will be,'if ∠1 +∠2 = 180° and if ∠1 +∠3 = 180°, then ∠2 =∠3'.
Given:
∠1 +∠2 = 90° and if ∠1 +∠3 = 90°, then ∠2 =∠3
To find:
The error in Jayden's reasoning
Solution:
According to Congruent Supplements Theorem, the sum of supplementary angles is equal to 180°, not 90°.
[tex]\angle 1 +\angle 2 = 180^o\\\angle 1 +\angle 3 = 180^o\\\text{From this, we can conclude that}:\\\angle 2 = \angle 3[/tex]
The error in Jayden's reasoning was 90°.
The correct statement will be,'if ∠1 +∠2 = 180° and if ∠1 +∠3 = 180°, then ∠2 =∠3'.
