A company makes steel rods shaped like cylinders. Each rod has a radius of 2 centimeters and height of 70 centimeters. How much steel will the company need to make 243 rods? Use 3.14 for pie, and round your answer to one decimal
Answer:
213,645.6cm³
Step-by-step explanation:
Area of a cylinder is expressed as;
V = πr²h
r is the radius = 2cm
h is the height = 70cm
Get the volume of one rod;
V = πr²h
V = (3.14)(2)²(70)
V = (3.14)(4)(70)
V = 879.2cm³
one steel = 879.2cm³
243 rods = x
Cross multiply;
x = 879.2 * 243
x = 213,645.6
The company will need 213,645.6cm³ volume of steel to make 243 rods

A triangle has a perimeter of 165 cm. The first side is 65 cm less than twice the second side. The third side is 10 cm less than the second side. Find the length of each side of the triangle.
What equation represents the length of the third side if the second side is length s?
2s - 10
2s + 10
s - 10
s + 10
Answer:
side - equation - measurement
1st side - 2s - 65 - 55cm
2nd side - s - 60cm
3rd side - s - 10 - 50cm
Step-by-step explanation:
total = 165
side - s
1st side = 2s - 65
2nd side = s
3rd side = s - 10
1st side + second side + 3rd side = 165
2s - 65 + s + s - 10 = 165
2s + s + s - 65 - 10 = 165
4s - 75 = 165
4s = 165+ 75
4s = 240
s = 60
1st side = 2s - 65
= 2(60) - 65
= 120 - 65
= 55cm
2nd side = s
= 60cm
3rd side = s - 10
= 60 - 10
= 50cm
3rd side is represented by s - 10 as it is less than the second side by 10cm hence taking away the 10 from the side forming the equation s - 10
Answer:
s-10

I NEED HELP NOW !!!!!!! In order for each sheep to get enough grass to eat, there should be 7 sheep for each acre of land. Which farm has the correct ratio of sheep to acres? Select the best answer from the choices provided. A. The Twelve Oaks farm has 14 sheep and 2 acres of land. B. The Tara farm has 28 sheep and 3 acres of land. C. The Butler farm has 35 sheep and 6 acres of land. D. The Scarlett farm has 21 sheep and 2 acres of land. 10 POINTS
Answer:
A: The Twelve Oaks farm has 14 sheep and 2 acres of land.
Step-by-step explanation:
For every 7 sheep, there has to be one acre of land. In order for you to find how many sheep are needed for each acre, you would multiply the amount of acres and you should get the amount of sheep that farm holds.
A. 2 x 7 = 14 meaning there should be only 14 sheep at a farm that only has 2 acres of land.
B. 3 x 7 = 21 meaning there should be only 21 sheep at a farm that only has acres of land.
C. 6 x 7 = 42 meaning there should be only 42 sheep at a farm that only has 6 acres of land.
D. 2 x 7 = 14 meaning there should be only 14 sheep at a farm that only has 2 acres of land.
Hope this helps!

The graph of a system of two linear equations is shown. How many solution does the system of equation have?
A. No Solution
B. Infinitley Many Solutions
C. Two Solutions
D. One Solution
Answer:
two solutions
Step-by-step explanation: it cant be no solution because no solution will be a vertical line it can be one solution becuase y=x is a solution and so is y=4
What us the answer?
Answer:
The graph so C
Step-by-step explanation:
Cause u can’t get two or more x values for different for one y value( if u plug in 3 and u get 5, u can’t plug in 3 again and get 10)
Use the given substitution and the chain rule to find
dy/dx
y=cos (6x - 5), u = 6x-5
Substituting u = 6x - 5, you write
y = cos(u)
Then differentiating with the chain rule gives
dy/dx = dy/du • du/dx
We have
dy/du = -sin(u)
du/dx = 6
so
dy/dx = -6 sin(u) = -6 sin(6x - 5)

The points (-1, 5) and (7, r) lie on a line with slope 5/4
Find the missing coordinate r.
Answer:
15
Step-by-step explanation:
7-(-1) is 8
8 divided by 4 (x or “run” of slope) is two
Two times five (y/rise of slope) is ten
5 (from original point -1,5) plus 10 is 15

Alfredo is buying a watch for $200. He will make an initial payment of $50 and
then pay the remaining balance in payments of $15 per week.
Which function can be used to find a, the amount he will still need to pay at the
end of n weeks?
Answer:
Step-by-step explanation:
There is nothing to choose from.
However, 200-50 down payment will leave 150 left on the watch. 150 divided 15 a month is 10 months.
200=50+15(n)
200=50+15(10)
