Answer:

$1,260

Step-by-step explanation:

You first need to find 30% of 1,800, which is 540. And then, because it's 30$<em> less than</em> retail price, you would need to subtract that from the initial price:

1,800-540 = 1,260

A certain kind of bacteria multiplies at a rate of 150 percent per hour. When a person’s blood has 45,000,000 of these bacteria,
DIA [1.3K]
Initial number of Bacteria = Ao = 100
Number of Bacteria which make the person ill = A = 45,000,000

Growth rate = r = 150% = 1.50 

The equation model for this situation is:

A= A_{o}(1+r)^{t}

Using the values in above equation, we can write:

45000000=100(1+1.5)^{t}  \\  \\ &#10;450000=(2.5)^{t} \\  \\ &#10;log(450000)=log((2.5)^{t})  \\  \\ &#10;log(450000)=t*log(2.5) \\  \\ &#10;t= \frac{log(450000)}{log(2.5)} \\  \\ &#10;t=14.21

This means, the person will fall sick after about 14 hours.

You need to buy a new cover for a pool.The pool is in shape of a trapezoid.The cost of the cover is .79.What is the total cost
jek_recluse [69]
Since we don't have the measurements for the trapezoid, we can't find the exact cost. However, I can explain how to solve the problem.

First, you need to find the the total area of the pool cover. Since it is in the shape of a trapezoid, use the formula below.

A = 0.5(h)(the sum of the bases)

Once you have the area, multiply by 0.79 and you will have the cost.
