8km - 24 minutes, to find the unit rate (how long it took to run 1km)
We would make a ratio,
8:24
Now just simplify,
8:24
=
1:3
Therefore the unit rate would be 1 kilometer covered for every 3 minutes.
Answer:
2/3
Step-by-step explanation:
Ratio is 2:3 since we have 6 and 9 for width. We can refer to 1:2:3 as 3:6:9, and apply the same thing for length 8 to where we have 4:8:12.
Answer:
7 tins of paint
Step-by-step explanation:
Surface Area of a Cylinder: 2(3.14)(r)(h) + 2(3.14)(r^2)
Radius: 0.7m
Height: 1.9m
Plug them in:
SA: 2(3.14)(0.7)(1.9) + 2(3.14)(0.7^2)
SA: 6.28(1.33)+6.28(0.49)
SA: 8.3524 + 3.0772
SA: 11.4296
Surface Area of Each Tank: 11.43m^2
11.43^2 x 3 = 34.29m^2
34.29m^2/5m^2 = 6.858 tins of paint rounded to 7 since you can't have 6.858 tins of paint
Answer:
12.35-4.30=8.05
8.05÷3= 2.68333333333333....
≈2.68
