Answer: 300
We know that 5×3=15. Since we are trying to get 1500 we Multiply 300×5 and get 1500.
<u>How do we know?</u>
- As you can see if you cross out 2 of the 0 in 300 you have 3×5. When you multiply it you get 15.
- Also if you cross out 1 of the 0 in 300 you have 30×5. When you multiply that you get 150.
As you see when you still multiply either of those problems you have 15 in it. So we should know 300×5=1500.
Note: We can also multiply 500×3 and get 1500. You still get the same answer but just switched numbers.
<em>1. x = - 7/3 = - 2 1/3</em>
<em>2. x = -2</em>
- Step-by-step explanation:
<em>Hi there ! </em>
<em />
<em>3x + 12 = - 6x - 9</em>
<em>3x + 6x = - 12 - 9</em>
<em>9x = - 21</em>
<em>x = - 21⁽³/9</em>
<em>x = - 7/3</em>
<em>x = - 2 1/3</em>
<em />
<em>12x + 20 = 2x</em>
<em>12x - 2x = - 20</em>
<em>10x = - 20</em>
<em>x = - 20/10</em>
<em>x = - 2</em>

<em>Good luck !</em>
Answer:
The correct option is A.
Step-by-step explanation:
The general exponential growth model is defined as
Where, a is initial value, r is growth rate and x is time.
The initial population of town is 9800 and growth rate is 2%. The population growth model is defined as
Put x=7 to find the estimated population after 7 years.
Therefore the correct option is A.
A = kdv^2 where A = amount oil d = distance and v = speed and k is a constant
so
30 = k*85*42^2
Now solve for k:-
k = 30 / (85*42^2) = 0.00020008
So when d = 26 and v = 54
Amount of oil A = 0.00020008 * 26*54^2
= 15.2 barrels
