What is one thousand five hundred divided by five equal
Vikki [24]

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.

3x + 12 = -6x - 9 and
Marianna [84]
  • Answer:

<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 />

<em>Good luck !</em>

Suppose the population of a town is 9,800 and is growing 2% each year. a. Write an equation to model the population growth. b. P
tiny-mole [99]

Answer:

The correct option is A.

Step-by-step explanation:

The general exponential growth model is defined as

f(x)=a(1+r)^x

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

f(x)=9800(1+\frac{2}{100})^x

f(x)=9800(1+0.02)^x

f(x)=9800(1.02)^x

Put x=7 to find the estimated population after 7 years.

f(x)=9800(1.02)^7

f(x)=11257.119543\approx 11257

Therefore the correct option is A.

The amount of oil used by a ship traveling at a uniform speed varies jointly with the distance and the square of the speed. the
muminat
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
