Convert $2 to cents, which is 200 cents.
10 cents =3 copies
200/10 =20
20x3 =60copies

or
10 cents =3copies,
100 cents =30copies.
100 x 2 =200cents.
2x30 copies =60 copies.

or in ratio form
10cents : 3copies
multiply 20 to get 200, you need to multiply on both sides,
= 200cents : 60copies

The answer is "152 ft"

Step-by-step explanation:

Please find the attached file.

The area of the square $(8 \times 5=40)$ can be found on the foot.

The area of the triangular front will then be calculated $(6\times 4=\frac{24}{2} = 12).$

Since each has two sides, $24+80=104$ .

Therefore the multiplying the area of the bottom square $(6\times 8=48)$ by the number of cells to get 152.

What is (4ab^0c^9)^3 ?

fomenos

Answer:

64a³c²⁷

Step-by-step explanation:

The expression inside parentheses can be simplified by noting that b^0 = 1. Then you have ...

(4ac^9)^3

The rules of exponents say the exponent outside applies to each of the inside factors. For c^9, the exponents multiply.

Here are the applicable rules:

(ab)^c = (a^c)(b^c)

(a^b)^c = a^(b·c)

__

(4ac^9)^3 = 4^3·a^3·c^(9·3) = 64a^3c^27
