A company makes steel rods shaped like cylinders. Each rod has a diameter of 8 centimeters and a height of 20 centimeters. If the company used 28,134.4 cm3 of steel, how many rods did it make?

Answers

Answer:

1,172.3 cm³

Step-by-step explanation:

Find the volume of one rod, then divide the total volume of steel used by the volume of one rod. The volume of one rod is

V = (πd²/4)h

d = 4 cm

h = 20 cm

Plugin the numbers and get V in cm³, then divide the given total volume of 28,134.4 cm³ by V. If the result is not an integer, then round down.

Add

20 + 4 = 24

Then

28,134.4 ÷ 24 = 1172.26

Rounded to the nearest 0.1 or the Tenths Place = 1,172.3

Therefore, 1,172.3 rods will be made per hour.

Answer:

(-1, -5)

Step-by-step explanation:

[tex]\left \{ {{y=5x} \atop {y=9x+4}} \right.[/tex]

1. We must calculate x, for that we must substitute y, so we have:

5x=9x+4

2. Now we solve the equation.

5x-9x=4

-4x=4

x=-1

3. Now we must calculate y

y=5x

y=5(-1)

y=-5

I did the PEMDAS method (P= parentheses, E= exponents, M= multiplication, D = Division, A= addition, S = subtraction.)

First I did what’s inside the parentheses, (6x2) and got 12.

Then I divided 16 by 22 and received 0.72.

I added 0.72 with 12 and the result was 12.72.

Last step was to subtract 12.72 - 8 and that equals 4.72

16 ÷ 22 + (6 x 2) - 8 = 4.72

At a restaurant, the cost for one breakfast taco and one glass of milk is $2.10.

The cost for two tacos and three glasses of milk is $5.15.

How much would it cost for 3 tacos and 4 glasses of milk

Answers

Answer: $7.25

Step-by-step explanation:

Let T = taco cost

Let M = milk cost

T + M = 2.10

2T + 3M = 5.15

Multiply the first equation by (-2) and add it to the second equation

-2T - 2M = -4.20

2T + 3M = 5.15

M = 0.95

Plug this value for M in to the first equation

T + 0.95 = 2.10

T = 1.15

So a taco costs $1.15 and the milk costs $0.95

1.15 * 3 = 3.45

0.95 * 4 = 3.80

3.45 + 3.80 = 7.25
