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.
Set up an equation. Since the ratio is 3:4 male:female, it would be 3m=4f. Since you know that 3m=18, solve for m and plug it into the 3m=4f equation to get the number of females! Don't forget that the number of females is 4f not just f!
Step-by-step explanation:
True
As long as the denominator isn't zero and can be expressed as a fraction with two non zero intergers., the number would be rational
Answer:
86
Step-by-step explanation:
32×4=128
128-42=86
Have you learned PEMDAS? (Parenthesis, exponents, multiplication, division, addition, subtraction). That is what I am going to do here.
The first parenthesis, let's solve. 7*10=70-5=65
The second parentheisis: I am assuming the negative sign is a typo, and this answer will be off if it is not. Sorry. 5*10=50
65*50=3250
I hope this helps, and let me know if you need further assistance.
