Step-by-step explanation: 13: 35x2= 70 70+35=105 not = to 100
Answer: 12 yd^3
Step-by-step explanation:
(base area x height)/3
1/2 x base x height = base
1/2 x 4 x 3 = 6
36/3 = 12yd^3
Let's write down what we know:
a=50+b
b=30+c
After one hour:
(a+50)*2=-70+3*(c+50)
let's eliminate the brackets:
2a+100=-70+3c+150
2a+100=+3c+80
which is:
2a=-20+3c
substituting from a=50+b:
100+2b=-20+3c
substituting from b=30+c
100+2(30+c)=-20+3c
100+60+2c=-20+3c
160+20=3c-2c
180=c.
So we know that c is equal to 40, then b will be b=30+c
b=30+180=210.
So B had 210 miles initially.
Answer:
The volume of a prism on its own = 248.5cm^3
The volume of a cylinder = 87.92cm^3
Step-by-step explanation:
The volume does not change for the prism as the hole was drilled.
We can show the drilled space with v(l) and (p) for prism V
v(l) 248.5p - 87.92p + 87.92p
= 248.5p
