Answer:

$12.85

Step-by-step explanation:

First we need to find the sale price of the CD

Sale price = old price - old price * discount rate

= 17 - 17* .3

= 17 - 5.1

= 11.9

The sale price of the CD is 11.90

Now we need to find the tax

tax = sale price of cd * tax rate

= 11.9 * .08

= .95

The final cost of the CD is sale price of CD plus the tax

Total cost = sale price of CD + tax

= 11.90 + .95

=12.85

a circular native american dwlelling has a diameter of 24 feet. how much are inside the home? use 3.14 for { } (pi)

Marizza181 [45]

Answer :

$A = 452.16 \: {ft}^{2}$

step-by-step explanation:

From the question,

the diameter:

$d = 24 \: ft$

The radius :

$r = \frac{diameter}{2}= \frac{24}{2}=12 \: ft$

$\pi = 3.14$

Area of a circle is given as

$A = \pi {r}^{2}$

By substitution,

$A = 3.14( {12}^{2} )$

$\implies \: A = 3.14 \times 144$

$\implies \: A = 452.16 \: {ft}^{2}$

Hence the area of the home is

$A = 452.16 \: {ft}^{2}$

Francis works at Carlos Bakery and is making cookie trays. She has 48 chocolate chip cookies, 64 rainbow cookies, and 120 oatmea

amm1812

The number of cookies and trays are illustrations of greatest common factors.

The number of trays is 8
6 chocolate chips, 8 rainbows and 15 oatmeal cookies would fit each tray

The given parameters are:

$\mathbf{Chocolate\ chip=48}$

$\mathbf{Rainbow=64}$

$\mathbf{Oatmeal=120}$

<u>(a) The number of trays</u>

To do this, we simply calculate the greatest common factor of 48, 64 and 120

Factorize the numbers, as follows:

$\mathbf{48 = 2 \times 2 \times 2 \times 2 \times 3}$

$\mathbf{64 = 2 \times 2 \times 2 \times 2 \times 2 \times 2}$

$\mathbf{120 = 2 \times 2 \times 2 \times 3 \times 5}$

So, the GCF is:

$\mathbf{GCF= 2 \times 2 \times 2}$

$\mathbf{GCF= 8}$

Hence, the number of tray is 8

<u>(b) The number of each type of cookie</u>

We have

$\mathbf{Chocolate\ chip=48}$

$\mathbf{Rainbow=64}$

$\mathbf{Oatmeal=120}$

Divide each cookie by the number of trays

So, we have:

$\mathbf{Chocolate\ chip = \frac{48}{8} = 6}$

$\mathbf{Rainbow = \frac{64}{8} = 8}$

$\mathbf{Oatmeal = \frac{150}{8} = 15}$

Hence, 6 chocolate chips, 8 rainbows and 15 oatmeal cookies would fit each tray
