All the items on the sale rack were 75 percent off their original price.
tresset_1 [31]

Answer:

112 $ is the original price

Step-by-step explanation:

x \times 0.75 = 84 \\ x = 84 \div 0.75 \\ x = 112

you have to think that the original price multiplied by 0.75 (also known as 75%) gave the result of what he saves i.e 84 $. So we put up an equation with the original price multiplied by 75% which equals the 84 $ he saved on buying that item on sale

vova2212 [387]

Answer:

The population will be 14708

Step-by-step explanation:

formula

A = P (1+r)^t

Initial population = P = 13000

Growth rate = r = 2.5% = 0.025

Number of years = t  = 5 years.

A = 13000 (1+.025)^5  = 14708

An object has been thrown straight up into the air. The formula h = vt - 16t^2 gives the height of the object above the ground a
Oxana [17]

Answer:

8 seconds.

Step-by-step explanation:

To solve this question, we need to find the time, t, when h = 0, that is, when the height of the object above the ground is 0 feet.

Substituting v = 128 feet per second and h = 0 gives  the quadratic:

0 = 128t - 16t^{2}

Since 128 is divisible by 16, it can be reduced to 0 = 16(8t - t^{2}).

We must now solve for t.

We can easily see that one answer to the equation is 0,

8(0) - (0)^{2} = 0 (we need not concern ourselves with the 16 outside of the parenthesis as in the equation above, since 16 multiplied by 0 is 0). However this is the time the object is released into the air.

The second answer, t = 8 is also easy to see by inspection:

8(8) - (8)^{2} = 0.

Therefore the object lands 8 seconds after it is thrown.
