3. Bob the Builder wants to earn an annual rate of 10% on his investments,

mamaluj [8]

Answer:

He should pay $2,790.7.

Step-by-step explanation:

This is a simple interest problem.

The simple interest formula is given by:

$E = P*I*t$

In which E is the amount of interest earned, P is the principal(the initial amount of money), I is the interest rate(yearly, as a decimal) and t is the time, in years.

After t years, the total amount of money is:

$T = E + P$

In this question:

Rate of 10%, so I = 0.1.

9 months, so $t = \frac{9}{12} = 0.75$

How much should he pay for a note that will be worth $3,000 in 9 months?

We have to find P for which T = 3000. So

$T = E + P$

$3000 = E + P$

$E = 3000 - P$

Then

$E = P*I*t$

$3000 - P = P*0.1*0.75$

$1.075P = 3000$

$P = \frac{3000}{1.075}$

$P = 2790.7$

He should pay $2,790.7.

A fish tank is 60cm long, 30cm wide, 40cm high and contains 70L of water. Rocks with a volume of 3000cm cubed are placed into th

hichkok12 [17]

The tank WILL overflow.

60*30*40= 72000cm^3

<em>The max volume the fish tank can hold: 72000cm^3</em>

amount of L * 1000= cm^3

70L * 1000= 70000cm^3

<em>There is already 70000cm^3 of water in the tank</em>

70000cm^3 + 3000cm^3 = 73000cm^3

The tank can only hold 72000cm^3 and the water and rocks are 73000cm^3, so the tank will overflow.

vodomira [7]

Answer:

Step-by-step explanation:

$\frac{x}{14} = \frac{40}{70} \\ x = \frac{40}{70} \times 14 \\ x = \frac{40}{10} \times 2 \\ x = 4 \times 2 \\ x = 8$
