I think its c but im not sure
Answer:
a) 9 miles/hour
b) 17.5 miles/hour
Step-by-step explanation:
The formula for speed = Distance (Miles) / Time(hours)
a) he can travel 3/4 of a mile in 5 minutes.
= 3/4 miles = 5 minutes
We convert 5 minutes to hour
= 60 minutes = 1 hour
5 minutes = x
Cross Multiply
60x = 5
x = 5/60
x = 1/12 hour
Hence, his skate speed =
3/4miles /1/12 hour
= 3/4 ÷ 1/12
= 3/4 × 12/1
= 9 miles/hour
b) On his bike, he can travel 3 1/2 miles in 12 minutes.
= 3 1/2 = 12 minutes
= 7/2 miles = 12 minutes
We convert 12 minutes to hour
= 60 minutes = 1 hour
12 minutes = x
Cross Multiply
60x = 12
x = 12/60
x = 1/5 hour
Hence, his skate speed =
7/2 miles /1/5 hour
= 7/2 ÷ 1/5
= 7/2 × 5
= 35/2 miles/hour
= 17.5 miles/hour
Answer:
Yes
Step-by-step explanation:
First add what she needs, and compare it to what she bought.
3/4 + 3 1/2 = 4 1/4. Compare 4 1/4 to 4 2/3. To do this, make them into singular fractions (not mixed number fractions), so you get 17/4 and 14/3. Then cross multiply (first number's nominator times the 2nd number's denominator) so 17x3=51. Then do the other sides (2nd number's nominator times the 1st number's denominator), so 14x4=56. Since 56 is greater than 51, then the 2nd number (14/3 or 4 2/3) is largest. Meaning that Maria has MORE than enough paint.
It doesn't, those aren't right
Answer:
Step-by-step explanation:
Remember, double the area and then divide by the known side length. To calculate the area of a triangle, we multiply the base times the height and divide by 2. If you are given the area, follow the steps backwards. You will multiply by 2 and divide by the given length.
