Answer:
Factor by which kinetic energy increase = 4 times
Step-by-step explanation:
Given,
- Mass of the car, v1 = 1500 kg
- initial speed of car = 35 miles/h

= 15.64 m/s
Initial kinetic energy of the car is given by,


= 183606.46 J
- Final velocity of car v2 = 70 miles/hour

= 31.29 m/s
So, final kinetic energy of car is given by


= 734425.84 J
Now, the ratio of final to initial kinetic energy can be given by,

Hence, the kinetic energy will increase by 4 times.
Answer:
$30.40
Step-by-step explanation:
Recurring debt is am amount paid for the debt service. It involves all the payment which could not be canceled on the request. It includes Child Support, Loan Payment etc.
A household is required to spend 28% of the gross income as housing expenses, but not above 36% of total debt.
Housing expense = 28% x 380 = $106.4
Expense on Debt = 36% x 380 = $136.80
So,
Allowable recurring debt having income of $380 = 136.80 - 106.40 = $30.4
Answer:
110÷360×π×4.6^(2)= 20.312
Step-by-step explanation:
Area of sector = angle / 360 x π x r^(2)
Answer:
7/3
Step-by-step explanation:
A proportion is a statement that two ratios are equal. A ratio is a comparison of two different quantities. "Miles per hour" is a ratio. "Dollars per pound" is a ratio. A proportion is that two of these things are equal.
For example, paying $2/pound for apples is the same as paying $6 for 3 pounds:

That's a portion.
When working with proportions in word problems, you start by setting up one ratio/fraction where you know all the information. You then set up the second one that's missing a piece of information, but you make sure to set it up using the same structure.
If your first ratio is "miles over hours," then the next ratio has to have the same organization.
If your first ratio is "rise over run," then the next ratio has to have the same organization.
