Lilit [14]

Answer:

1) 62.5

2) 50

3) 75

4) 100

Step-by-step explanation:

1)

Because it has a half-life of 25 days, half of it will decay after 25 days.

After 25*4=100 days, there will be (1/2)^{4}=1/2^{4}=1/16 of it left.

So, 1000/16=\boxed{62.5}.

2)

Because it has a half-life of 25 days, half of it will decay after 25 days.

After 25*3=75 days, there will be (1/2)^{3}=1/2^{3}=1/8 of it left.

So, 400/8=\boxed{50}

3)

Because it has a half-life of 25 days, half of it will decay after 25 days.

After 25*2=50 days, there will be (1/2)^2=1/2^{2}=1/4 of it left.

So, 300/4=\boxed{75}.

4)

The only answer left is \boxed{100} grams. You can solve it the same way you solved the previous steps.

A bike shop rents bikes for $4.50 per hour, plus a $7.50 insurance charge. For how many hours can Peter rent a bike if he has $3
Mandarinka [93]

Answer:

With $30, Peter can afford 5 hours

Step-by-step explanation:

Given

Insurance Charge = $7.5

Charges = $4.5 per hour

Required

Determine the number of hours $30 can afford

First, we need to determine the equation.

<em>Total Charges = Charges per hour + Insurance Charge</em>

Substitute values for Charges per hour and Insurance Charge

Total Charges = 4.5 per hour + 7.5

Let the number of hours be n;

So,

Total Charges = 4.5n + 7.5

To calculate Peter's; substitute 30 for total charges

30 = 4.5n + 7.5

Subtract 7.5 from both sides

4.5n = 30 - 7.5

4.5n = 22.5

Divide both sides by 4.5

n = \frac{22.5}{4.5}

n = 5

Hence;

<em>With $30, Peter can afford 5 hours</em>
