Answer:
1.36mph
Step-by-step explanation:
The escalator is moving at 2ft/s, lets convert this to miles/second.
2ft/s = 0.000378788miles/s.
Now that we have the miles/second lets multiply this value by 3600 to get the miles/h, because there are 3600 seconds in an hour.
2ft/s=1.3636368miles/h
Or approximately 1.36miles/h.
Answer:
The cost of 12 gallons of gas and a quart of oil is 14·x - 30
Step-by-step explanation:
When adding variables, the coefficient of the variables are added followed by multiplication of the sum of the coefficients with variable as follows;
The cost of 12 gallons of gas = 12·x
The cost of a quart of oil is represented by 2·x - 30
Therefore, the cost of 12 gallons of gas and a quart of oil can be represented as follows;
12 gallons of gas and a quart of oil = 12·x + 2·x - 30
Which gives;
The cost of 12 gallons of gas and a quart of oil = 14·x - 30.
Answer:
doyour work and stop looking up answers but the answer is Two lines are parallel if they are at a constant distance apart
Step-by-step explanation:
It's not possible for the smaller number to be larger than the larger number when multiplied by the same value. Is this stated correctly?
1 3 5
2 * 1 = 2
2 * 5 = 10
the smaller number cannot exceed the larger number.
The d=rt formula is used in this situation where d=distance, r= speed, and t= time.
So plug in your variables and numbers to get;
distance=400*h
Hope this helps.
