Step-by-step explanation:
for this we need to know the conversion rate between miles and kilometers :
1 mile = 1.60934 km
which means
1 km = 0.621371 miles
so,
70 m/h = 70×1.60934 km/h = 112.6538 km/h
compared to the 120 km/h limit in Canada, it is clear that the speed limit in Canada is higher.
the difference is
7.3462 km/h = 7.3462×0.621371 = 4.56471564 m/h
Answer:
Solution given:
B=12.56cm²
P=12.56cm
H=6cm
Surface area of cylinder=P*H+2B=100.48cm²
Volume=B*H=12.56*6=75.36cm³
I believe the answer is A
Answer:
1) 28.4 miles per gallon
2) 34 miles per gallon
3) the red car
Step-by-step explanation:
Blue car:
Travels 35 1/2 miles on 1 1/4 gallons of gasoline
Red car:
Travels 27 1/5 miles on 4/5 gallons of gasoline
We want to know the unit rate for miles per hour, and to do it we have to divide the miles they travel by the gallons each car uses:
Blue car:
(35 1/2) / (1 1/4) = 28.4 miles per gallon
Red car:
(27 1/5) / (4/5) = 34 miles per gallon
The red car travels greater distance with 1 gallon of gasoline {and thats about it!}
Check the picture below.
notice, the gift box is just 6 rectangles stacked up to each other at the edges,
left and right, two rectangles of 32x40
top and bottom, two rectangles of 25x32
front and back, two rectangles of 25x40
so, just get the area of all 6 rectangles, add them up, and that's the "surface area" of the rectangular prism, and that's how much paper will be needed to cover it.
