</span> answer
(-2c-3d) (- 11) = 22c + 33d
(66c + 99d) * 1/3 = 22c + 33d
11 * ( 2c+3d) = 22c + 33d
a)
Answer: 0.91 m
Explanation:
We know that,
P.E. = m g h
Where,
P.E = Potential energy
m = Mass of the object
g = acceleration due to gravity (9.8 m/s²)
It is given that, m = 1.5 kg
P.E. = 13.44 J
⇒ 13.44 = 1.5 kg × 9.8 m/s² × h
⇒ h = 0.91 m
Hence, apple sits om 0.91 m tall counter.
b)
Answer: 216 J
Explanation:
P.E. = m g h
Weight, mg = 120 N ( given)
height, h = 1.8 m ( given)
The energy possessed by the suitcase is due to virtue of its position (gravitational potential energy)
P.E. = 120 N × 1.8 m = 216 J
Hence, the energy possessed by the suitcase sitting on the counter is 216 J.

Answer:
Total cost of repayment is $10,852.92
Step-by-step explanation:
Firstly, we need to calculate the interest attached to this loan repayment
To calculate this, we use the formula for simple interest
Mathematically,
I = 
where P is the amount borrowed which is $9,000
R is the rate which is 4.5%
T is the time which is 3 years
Plugging these values, we have
I = (9000×4.5×3)/100 = $1,215
Now we were also told in the question that she will make a monthly repayment of $267.72
Now the number of months in 3 years is 36 months. Total monthly repayment = 267.72 × 36 = $9637.92
Adding the interest amount, we have 9637.92 + 1215 = $10,852.92
