Answer:
3 miles per hour
Step-by-step explanation:
he runs 1/3 mile in 1/9 of an hour
then
he runs (we multiply both sides by 9)
9×(1/3) mile in 9×(1/9) of an hour
then
he runs
(9/3) mile in (9/9) of an hour
then
he runs
3 mile in 1 hour
379 * 8 = 3032
If the answer choices are:
A. Between 2,400 and 2,500
B. Between 2,400 and 2,800
C. Between 2,400 and 3,000
D. Between 2,400 and 3,200
Then the answer is D. Between 2,400 and 3,200.
55% of 79.95
Find 10% = 7.995
5 x 7.995 = 39.975
Find 5% of the 10% = 3.9975
Add the 5% + 50% amounts together
39.975 + 3.9975 = 43.9725
50% decrease then 100% increase: same as the original; the number is halved then that new number is doubled, which brings it back to the original, x * 2 * ¹/₂ = x (¹/₂ and 2 cancel out)
50% increase then 33¹/₃% decrease: same as the original; x * ³/₂ * ²/₃ = x (³/₂ and ²/₃ cancel out)
20% increase then 25% decrease: less than the original ; x * ⁶/₅ * ³/₄ = ⁹/₁₀x
$10 increase then $10 decrease: same as the original; x + 10 - 10 = x
25% increase then 20% decrease: same as the original; x * ⁵/₄ * ⁴/₅ = x
