Answer:
15%
Step-by-step explanation:
The quantities must be in the same units
Using the conversion
I hour = 60 minutes, then
3 hours 20 minutes = ( 3 × 60) + 20 = 180 + 20 = 200 minutes.
Thus
× 100% = 
= 15%
Answer:
h(0)=10
h(4)=16
Step-by-step explanation:
for h(0) you would need to do the second equation because it is within the bounds of the variable.
h(0)= 2x^2 - 3x + 10
anything times 0 is 0
so 2(0)^2 - 3(0) + 10=
0-0+10=
10
h(4) would use the third equation since it's the only one that agrees with the variable 4
2^4=16
Answer:
20
Step-by-step explanation:
5 plus 7 plus 10 plus 3 = 25
25x4=100
5x4=20
20%
Another way
5/25 = 0.2
0.2 =20%
The answers comes to be for every 1 unit of pure acid (100%) add three units of 20% and you get the desired 40%
so if you need 40 L (i don't know what container sizes there are so i can't give you an exact amount just add 1 part 100% acid and 3 parts 20% acid) <span />
Answer:
4.24 inches
Step-by-step explanation:
1 inch / 50 miles = x / 212 miles Cross multiply
1 inch * 212 miles = 50 miles * x Divide by 50 miles
1 inch * 212 miles / 50 miles = x
x = 4.24 inches.
How much is 0.24 of an inch?
0.24 * 50 = 12
So 0.24 inches represents 12 miles.
