Answer:
about 130 hp
Step-by-step explanation:
The displacement is smaller by a factor of 220/390, so we expect the horsepower to be smaller than 230 hp by the same factor:
(220/390)(230 hp) ≈ 129.74 hp ≈ 130 hp
Answer:
hours.
Step-by-step explanation:
We have been given that a chemical spill is leaking into a river flowing 2 3/4 miles per hour.
To find the time taken by chemical to reach the town we will divide distance of town from the spill by distance covered by chemical spill in one hour.
Upon converting our mixed fractions into improper fractions we will get,
Dividing a fraction with another fraction is same as multiplying first fraction by the reciprocal of second fraction.
After cancelling out 4 we will get,
Therefore, it will take the chemicals hours to reach the town.
Answer:
It means that above 0 degrees Celsius the water does not freeze, whereas 0 degrees are freezing teperatures of water.
Step-by-step explanation:
Water freezes at 0 degrees Celsius, but the freezing temperature can be lowered by adding salt to the water. A student discovered that adding half a cup of salt to a gallon of water lowers its freezing temperature by 7 degrees Celsius. What is the freezing temperature of the gallon of salt water?
0° - 7° = -7°
Answer:
the last option
Step-by-step explanation:
test with point (1,6):
x=1 and y=6
4x + 5y - 34 = 0
4(1) + 5(6) - 34 = 0
0 = 0
test with point (6,2)
x=6 and y=2
4x + 5y - 34 = 0
4(6) + 5(2) - 34 = 0
0 = 0
