Answer:

She decreased her running time at a rate of 16.67%

Step-by-step explanation:

In this question, we are asked basically to calculate the percentage decrease in Abby’s running time.

Mathematically, the percentage decrease equals: (new running time - old running time)/old running time * 100%

We input the values and proceed as follows:

Percentage decrease = (10-12)/12 * 100

-2/12 * 100/1 = -1/6 * 100 = -16.67%

Since it’s a decrease, we just simply say that her running time decrease by 16.67%

Nikki just graduated from high school and would like to buy a car. If she received $3000 in graduation gifts from family friends
svetlana [45]

Answer:

$3450

Step-by-step explanation:

Here, P = $3000, N = 1.5 years, R = 10%

SI = \frac{PNR}{100}  \\  \\ SI = \frac{3000 \times 1.5 \times 10}{100}   \\  \\ SI = 450 \\  \\

Amount of down payment

= $3000 + $450

= $3450

Hello from MrBillDoesMath!

Answer:  B

Remark:   It is customary to use x^2,  not x2, to indicate the square of x.


Discussion:

(4x + 3) ^ 2=   ( 4x)^2 + 2 * (4x)(3) + 3^2 =

                       16 x^2 + 24x  + 9


Thank you,

Order the situations from the account that yields the greatest amount to one that yields the least amount.
Bumek [7]

Answer:

Order from the greatest yield to the least as follows

1. Situation B=$2,119.8949

2. Situation A=$2,095.3078

3. Situation C=$2,022.7789

Step-by-step explanation:

Situation A

A=P(1+r/n)^nt

=500(1+0.12/12)^12*12

=500(1+0.01)^144

=500(1.01)^144

=500(4.1906155936008)

=$2,095.3078

Situation B

A=P(1+r/n)^nt

=500(1+0.1/4)^4*15

=500(1+0.025)^60

=500(1.025)^60

=500(4.3997897488150)

=$2119.8949

Situation C

A=P(1+r)^t

=500(1+0.15)^10

=500(1.15)^10

=500(4.0455577357079)

=$2022.7789

Order from the greatest yield to the least as follows

1. Situation B=$2,119.8949

2. Situation A=$2,095.3078

3. Situation C=$2,022.7789
