Answer:
Below.
Step-by-step explanation:
The area = the height (h) times the base.
So Q2:
21 = h * 7
h = 21/7 = 3
55 = b * 5
b = 11.
18.75 = h * 7.5
h = 18.75 / 7.5
= 2.5.
Answer:
2 miles and 88 yards.
Step-by-step explanation:
4 has 2*2 as prime factors
5 is prime
10 has 2 and 5 as prime factors
Thus, the lowest common denominator will be 2*2*5
3/4=15/20
3/5=12/20
7/10=14/20
Now that we have three fractions with the same denominator, we can add the numerators
15+12+14=41
So 41/20ths
That’s 2 and 1/20th
So the final answer is 2 miles and 88 yards! :)
Answer:
2.5 days
Step-by-step explanation:
The planned production rate was ...
(4500 dresses)/(25 days) = 180 dresses/day
The actual production rate was ...
180 dresses/day + 20 dresses/day = 200 dresses/day
So the actual time required for production of 4500 dresses was ...
(4500 dresses)/(200 dresses/day) = 22.5 days
That is the time required was less by ...
25 days -22.5 days = 2.5 days
The company finished 2.5 days early.
The volume of a cone is (1/3)pi r^2 and of a cylinder it is just pi r^2. So the volume of the cylinder will be 3 times that of the cone with the same base and height. So V_cylinder = 36 pi inches^3
Remember: inches is a unit of length in 1D. For 3D volume use inches^3
12 × 5 = 60
12 nickels
10 × 2 = 20
2 dimes
60 + 20 = 80
