16400*0.0825= 1353

1353*10= 13530

16400-13530= $2870

Answer:

$6932.73.

Step-by-step explanation:

Principal = $16400

Rate of decrease = 8.25%

Now we are supposed to find What will the value of the car be, to the nearest cent, after 10 years?

Formula : A=P(1-\frac{r}{100})^t

where A is the amount

r is the rate of decreasing in % =8.25%

t is the time =10

P is the principal =$16400

Substituting the values:

A=16400(1-\frac{8.25}{100})^{10}

A=6932.734

Hence the value of the car after 10 years will be $6932.73.

A right cylinder has a radius of 2 units and height of 5 units. What is the volume of the cylinder? Round to the nearest tenth.
Free_Kalibri [48]

Hi,

The volume of the cylinder is :

V = π × r^2 × h

V = 3,142 × (2)^2 × 5

V = 62, 8319 cm^3

π : Pi => 3,142

r : radius of the cylinder (2 units).

h : height of the cylinder (5 units).

The base of the cylinder is a circle , so to calculate the area we have to use the formula : area = π × r^2. And to find the volume , we have to multiply the area by the height.

Seventh graders collected some gold sand on a class field trip.
satela [25.4K]

Answer:

Class 7A collected 4.8 ounces of pure gold.

Step-by-step explanation:

<u>Key skills required are: Percentages, Multiplication</u>

<u />

  1. We only need the information about Class 7A. They collected 40 oz that contains 12% gold.
  2. In other words, this means that 12% of that 40 oz gold sand is pure gold.

Here we have to do 12% x 40 to find the number of oz of pure gold. We first have to convert 12% into a decimal. Divide it by a 100 (or move the decimal point 2 places to the left) and you will get 0.12.

<em>Do 0.12 x 40 and you will get 4.8</em>

Therefore, there are 4.8 oz of pure gold in Class 7A's gold sand
