There are 2000 pounds in a ton - so the rino weighs 3.75 x 2000 = 7500 pounds
a percentage can be converted to a decimal - if you want to know what 3.8% of a number is, move the decimal two spaces to the left 3.8% is 0.038 -
Multiply 7500 pounds by 0.038 - the answer is 285 pounds.
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:
9
Step-by-step explanation:
Answer:
The system of equation to model the situation are:
C = 10t + 8
C = 12t
Step-by-step explanation: Complete question ( Let C be the total cost and let t be the number of tickets).
Ordering tickets online cost $10 plus additional service charge of $8.
Therefore total cost,C = 10t + 8
Buying tickets at the door cost $12
Therefore, total cost,C = 12t
The system of equation to model the situation are:
C = 10t + 8
C = 12t
Answer:
<u>41 years ago</u>
Step-by-step explanation:
Let the no. of years ago be x.
Then, the equation we need would be :
=> 80 - x = 3(54 - x)
=> 80 - x = 162 - 3x
=> 2x = 82
=> x = 41
Sally's mother was 3 times her age <u>41 years ago</u>
Checking
=> Sally = 54 - 41 = 13
=> Mom = 80 - 41 = 39
=> 13 x 3 = 39 [∴Verified]
