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

This is just simple addition so there really isn't anything to talk about.
Just note that -5 1/2+6 3/4=1 1/4.
Then, we do 1 1/4+(-4 1/4)
This is just -3.
A map has a scale of 5 in. = 15 mi. If you measured the distance between two cities to be 26 in. On the map, how many miles would it actually be? If necessary, round your answer to the nearest tenth.
Answer:
Actual distance between the two cities given on the map = 78.0 miles
Step-by-step explanation:
Scale used for the actual distance between two cities on a map is,
5 in. = 15 mi.
[tex]\frac{5}{15}[/tex] in. = [tex]\frac{15}{15}[/tex] mi.
1 mi. = [tex]\frac{1}{3}[/tex] in.
1 inch = 3 miles
Therefore, 26 inches on the map = 26 × 3
= 78 miles
Therefore, actual distance between the two cities given on the map = 78.0 miles
someone help Slope from graph
1) Solve for Side A.
2) Solve for Angle B.
Best answer will receive Brainliest.
solution given;
let
AB=a
AC=b=30ft
AB=c=20ft
<A=115°
By using Cosine rule.
a²=b²+c²-2bc cos angle
a²=30²+20²-2*30*20 Cos 115°
a²=1807.1419
a=√[1807.1419]
a=42.51
Side A is 42.51ft.
Again
Cos B=[tex] \frac{a²+c²-b²}{2ac} [/tex]
Cos B=[tex] \frac{42.51²+20²-30²}{2*42.51*20} [/tex]
Cos B=0.7687
<B=Cos -¹(0.7687)
<B=39.46°
Angle B is 39.46°

A group of girls plays 2 hours of video games. They equally share the playing time between the 4 of them. How many minutes of play time does each girl get?
Answer: A: 30
Step-by-step explanation: 2 hours in minutes is 120 minutes.
(60 minutes is in an hour so multiply 60 * times 2=120)
120 divided by 4 is 30. You're splitting 120 minutes into 4 pieces.
30 is the answer. Happy Women's Month! #BeBrainly
half-life of Po-210 is 140 days. If the initial mass of the sample is 5
kg, how much will remain after 420 days.
Answer:
[tex]0.625kg[/tex]
Step-by-step explanation:
we are given half-life of PO-210 and the initial mass
we want to figure out the remaining mass after 420 days
in order to solve so we can consider the half-life formula given by
[tex] \displaystyle f(t) = a {0.5}^{t/T} [/tex]
where:
f(t) is the remaining quantity of a substance after time t has elapsed.a is the initial quantity of this substance.T is the half-lifesince it halves every 140 days our T is 140 and t is 420. as the initial mass of the sample is 5 our a is 5
thus substitute:
[tex]\displaystyle f(420)=5\cdot{0.5}^{420/140}[/tex]
reduce fraction:
[tex]\displaystyle f(420)=5\cdot{0.5}^{3}[/tex]
By using calculator we acquire:
[tex]\displaystyle f(420)=0.625[/tex]
hence, the remaining sample after 420 days is 0.625 kg

A. 12x+6y
B. 12x+24y
C. 2 (6x+12y)
D. 4 (12x+24y)
Answer:
the answers are b and c
Step-by-step explanation:
b
[tex]12x + 24y = \\ 4(3x + y)[/tex]
c
[tex]2(6x + 12y) = \\ 12x + 24y = \\ 4(3x + 6y)[/tex]

person 6-9 MathXL 8th grade question 2
Answer:
<1 = 112degrees
<2 = 33degrees
Step-by-step explanation:
From the figure, the sum of interior angles of the larger triangle is equal to the exterior, hence;
<1 + 15 = 127
<1 = 127 - 15
<1 = 112degrees
For the smaller triangle;
<1 = <2 + 79
112 = <2 + 79
<2 = 112-79
<2 = 33
Hence the measure of <2 is 33degrees

Jimmy bought a refrigerator that cost $525 before tax. He paid 8% of this amount in tax. What was the total cost of the refrigerator including tax?
Answer:
$567 after tax
Step-by-step explanation:
first, let's multiply 525 by 0.08 because he paid 8% (0.08) of 525 in tax.
525(0.08)= 42
now, let's add them together, because the question asks for the total cost.
525+42=567
$567 after tax

Answer:
a = 0, b = 7
a = 1, b = 6
a = 2, b = 5
a = 3, b = 4
a = 4, b = 3
a = 5, b = 2
a = 6, b = 1
a = 7, b = 0
Step-by-step explanation:
the sum of a and b must equal 7 because 4 x 7 = 28
2 x [(27–3) - (3+4)] = n
what’s (n)
Answer:
n = 34
Step-by-step explanation:
2{(24- ( 3 + 4)) =n
2{(24 - 7) =n
2 x 17 = n
34 = n
swap the sides
n = 34
