Answer:
10 miles in 50 minutes
Step-by-step explanation:
1. Divide 20 into 4 to see the unit rate of 1 mile.
2. If you continue on from 20 to 50 you will notice it will be 10 miles.
You welcome.
Answer:
V≈11.99π
Step-by-step explanation:
1/3hπr^2 = volume of a cone
(4/3πr^3)/2 = volume of a hemi sphere
Volume of the cone
1/3(5)π(2)^2
1/3(5)π(4)
1/3(20)π
Volume of the cone is ≈ 6.66π
Volume of the hemi sphere
(4/3π(2)^3)/2
(4/3(8)π)/2
(10.66π)/2
volume of the hemi sphere is ≈ 5.33π
5.33π + 6.66π =11.99π
N is the number of the Tshirt
c is the cost
the relationship between the cost and the number of the Tshirt is:
12n+3=c
so if 1 is the number of the tshirt so the cost is
12.1+3=12+3=15
if n=2 c=12.2+3=24+3=27
and etc.....
