Emily makes cylindrical bars of soap to sell online. Each bar has a radius of 3.5 cm and a length of 4 cm. Each bar is wrapped in plastic before shipping. In terms of π, how much plastic will Emily need to ship 20 bars of soap?
A) 52.5π cm2
B) 110π cm2
C) 1050π cm2
D) 1075π cm2
Answer:
C) 1050π cm²
Step-by-step explanation:
Surface area of a cylinder = 2πrh + 2πr²
radius, r = 3.5cm
Height, h = 4 cm
Surface area of a cylinder = 2πrh + 2πr²
= 2 * π * 3.5 * 4 + 2 * π * 3.5²
= 28π + 2π * 12.25
= 28π + 24.5π
= 52.5π cm²
Surface area of a cylinder = 52.5π cm
There are 20 bars of soap
Total plastic Emily needs for 20 bars of soap = surface area of each soap × 20
= 52.5π cm² × 20
= 1,050π cm²

Question 1 of 10
If there are 8 successful outcomes in a sample with a size of 25, what is the
sample proportion?
A. 0.96
B. 0.76
C. 0.32
O D. 0.52
yo help me please if u can’t see please zoom in i need help asap
Answer:
96
Step-by-step explanation:
once you fill in the Blanks that are solvable, you will work your way into the answer. For example, the first column, the missing number has to be 155-76 or 79. Now you can find your answer. In the second row, “no Laptop”, you have 79 (solved above) plus 17. So your answer is 79+17 or 96.

Use elimination/linear combination to solve the following.
please help
Answer:
Step-by-step explanation:
3x + 4y = 17
5x - 4y = 7
you can thus cancel out 4y
Hence
8x = 24
Hence x = 3
Substituting’
3(3) + 4y = 17
9 + 4y = 17
Hence 17 - 9/4
= y = 2
Hope this helps

Answer: The last option has no solution.
1. ) The solution is 1/2
2) The solution is -17/27
3) The solution is infinitely many solutions.
4) There is no solution because the answer solved and simplified comes out to be 17= -10; this is impossible so there is no solution
Answer:
5(2.2y + 3.4) = 5(y - 2) + 6y
Step-by-step explanation:
In order to answer this question, one must solve each of the equations until one has reached a conclusion that the parameter (y) has no solution in the given circumstance.
Equation 1
13y + 2 - 2y = 10y + 3 - y
Simplify, combine like terms;
11y + 2 = 9y + 3
Inverse operations,
11y + 2 = 9y + 3
-9y
2y + 2 = 3
-2
2y = 1
/2
y = 0.5
Equation 2
9(3y + 7) - 2 = 3(-9y + 9)
Distribute, multiply every term inside the parenthesis by the term outside of it;
(9)(3y) + (9)(7) - 2 = (3)(-9y) + (3)(9)
Simplify,
27y + 63 - 2 = -27y + 27
27y + 61 = -27y + 27
Inverse operations,
27y + 61 = -27y + 27
+27y
54y + 61 = 27
-61
54y = 34
/54
y = [tex]\frac{17}{27}[/tex]
Equation 3
32.1y + 3.1 + 2.4y - 8.2 = 34.5y - 5.1
Simplify, combine like terms;
34.5y - 5.1 = 34.5y - 51
As one can see, this equation is an identity, meaning that any value can be substituted into the parameter (y) to produce a true result.
Equation 4
5(2.2y + 3.4) = 5(y - 2) + 6y
Distribute, multiply every term in the parenthesis by the term outside of it;
(5)(2.2y) + (5)(3.4) = (5)(y) + (5)(-2) + 6y
Simplify,
11y + 17 = 5y - 10 + 6y
11y + 17 = 11y - 10
Inverse operations,
11y + 17 = 11y - 10
-11y
17 = -10
One can see that this equation produces a false result since it is common knowledge that (17) cannot equal (-10). Therefore, this equation has no solutions.
2x + 3y = -60
2x + 3y = 120

Melanie uses 13
1
3
of her supply of cranberries to make bread and 49
4
9
of her supply of cranberries to make granola. If Melanie uses 7 pounds of cranberries, how many pounds of cranberries are in her supply?
Answer:
She has 9 pounds
Step-by-step explanation:
Given
[tex]Bread = \frac{1}{3}[/tex]
[tex]Granola = \frac{4}{9}[/tex]
[tex]Used = 7[/tex]
Required
The total in her supply
Represent the cranberry with c.
So:
[tex]\frac{1}{3}c + \frac{4}{9}c = 7[/tex] ---- Used cranberry
Take LCM
[tex]\frac{3c + 4c}{9} = 7[/tex]
[tex]\frac{7c}{9} = 7[/tex]
Solve for c
[tex]c= 7 * \frac{9}{7}[/tex]
[tex]c= 9[/tex]

Answer:
81 un²
Step-by-step explanation:
9 · 7 = 63 un²
(b · h) ÷ 2
(5 · 4) ÷ 2 = 10 un²
(4 · 4) ÷ 2 = 8 un²
8 un² + 10 un² + 63 un²
81 un²
Answer:
81 un^2
Step-by-step explanation:
Find area of the rectangle. 9 x 7 = 63
Find area of the triangle. 9 x 4 = 36/2=18
63 + 18 = 81
Find the equation of the line perpendicular to the line 6y-18x=12 that pases through the point (0, -5)
Answer:
y = -x/3 -5
Step-by-step explanation:
when two lines are perpendicular, the relation between the slopes of the lines m1 and m2
m1m2 = -1
The general equation of a line is given as
y = mx + c where m is the slope and c is the intercept
Considering the given equation
6y-18x=12
6y = 18x + 12
Divide through by 6
y = 3x + 2
comparing with y = mx + c,
m = 3
hence the slope of the perpendicular line m2
= -1/3
Given that the line passes through the point (0, -5)
Using the equation y - y1 = m(x - x1) to find the equation
y - - 5 = -1/3(x - 0)
y + 5 = -x/3
y = -x/3 -5

Find the volume
V=bh
* B is length times width
Answer:
448 yd^3
Step-by-step explanation:
V = Bh where B is l * w
V = l*w*h
V = 8* 14* 4
=448 yd^3
Answer:
The volume of this rectangular prism is equal to [tex]448yd^{3}[/tex].
Step-by-step explanation:
From the question, we know the formula for the volume of a rectangular prism is V = Bh (where B is length times width, and "h" is the height).
Now we replace B (because we know that B is length times width) and get...
V = lwh (where "l" is the length of the prism, and "w" is the width of the prism.
Now we just substitute the values and get...
[tex]V = lwh = (14)(4)(8) = 448yd^{3}[/tex]

Algebra homework jimthompson
Answers:
B) 66%C) 34%See the diagram belowC) 86% of the people who studied passed the quiz.===================================================
Explanations:
Problem 1
We have B = 62+32 = 94 people who wear a belt. Of this total, A = 62 belt wearers also have a watch. So A/B = 62/94 = 0.6596 = 65.96% = 66% of the belt wearers have a watch. This value is approximate.
-------------------------------
Problem 2
In the previous problem we found that roughly 66% of the belt wearers have a watch. This must mean about 100% - 66% = 34% of the belt wearers do not have a watch.
-------------------------------
Problem 3
The question is "Among left handers, what proportion has neat handwriting?" which means we're effectively only concerned with the first row that says "left-handed". In this row, there are 5 who write neat, and 10 who do not. We have B = 5+10 = 15 people who are left-handed. We'll divide everything in this row by this value of B.
So for A = 5, it turns into the approximate proportion A/B = 5/15 = 0.33 meaning that about 33% of the left-handers have neat handwriting.
For the other value in this row, A = 10 turns into A/B = 10/15 = 0.67 = meaning that about 67% of the left-handers have messy hand writing.
You'll do the same thing for row 2, but you'll divide everything by B = 65 (because there are 34+31 = 65 right-handed people total).
The filled out table is shown below.
-------------------------------
Problem 4
Let's say we ignore the percentage signs. Adding the values across the first row gets us B = 86+14 = 100 people who passed the quiz. Of that, A = 86 people who passed also studied as shown in the top left corner.
We can then see that A/B = 86/100 = 86% of the people who passed the quiz also studied. Notice the phrasing here. It's not the other way around. We would not say "86% of the people who studied passed the quiz". Your teacher has the order swapped unfortunately. If choice C said "86% of the people who passed the quiz studied for the test", then it would be fully correct. However, I think that's what they were going for and made a typo.
If we did state that "86% of the people who studied passed the quiz", then we'd be considering the first column instead of the first row. However, note how the percentages in the first column do not add to 100%.

Answer:
10
Step-by-step explanation:
6-3=3 then power of 2 which is 9 then plus 1
Answer:
C
Step-by-step explanation:
Substitute 6 for "x" in (x - 3)² + 1
(6 - 3)² + 1
We now evaluate the expression using PEMDAS
Parenthesis
Exponents
Multiplication and division ( from left to right )
Addition and subtraction ( from left to right )
Step 1: parenthesis
6 - 3 = 3
We would then have (3)² + 1
step 2: exponents
3²=9
we would then have 9 + 1 which = 10
Hence, the answer is C
