Answer:

\huge\boxed{\sf \$ \ 26.24}

Step-by-step explanation:

Each side of the squared painting = 41 inches

A square has 4 sides. So,

4 sides of the square painting = 4(41) inches

                                                  = 164 inches

\rule[225]{225}{2}

<u>The shop charges:</u>

1 inches = $ 0.16

Multiply both sides by 164

164 inches = $ 0.16 × 164

164 inches = $ 26.24

\rule[225]{225}{2}

Hope this helped!

F(x)=(x^3+4x^2+7x-9) d(x)=(x+3)<br><br> divide using long division
Alchen [17]

The result is x^2 +x +4 -21/(x+3).

_____

Polynomial long division tends to be easier than numerical long division because the quotient term never needs adjustment. It is always the ratio of the highest degree terms of the dividend and divisor.

See the attachment for the intermediate steps.

Kim has a strong first serve; whenever it is good (that is, in) she wins the point 70% of the time. Whenever her second serve is
mestny [16]
Lets put ti this way:
P[1st serve good & wins point] = 60% * 70% = 42% = A 
<span>P[2nd serve good & wins point] = 40% * 76% *57% = 17.328% = B </span>

<span>1. P[win point] = A+B = C = 59.328% <------- </span>
<span>2. P[1st serve good | win point ] = A/C = 42 / 59.328 = 0.707 or 70.7%
Please </span><span>remember that 2nd serve come into use only if 1st serve is not good</span>

write the product of the expression 5^4 * 5^-7 using a positive exponent, then write the product using a negative exponent
pav-90 [236]

Answer with positive exponent = \left(\frac{1}{5}\right)^3 or  \frac{1}{5^3}

Answer with negative exponent = 5^{-3}

===========================================================

Explanation:

The rule we use is

a^b*a^c = a^{b+c}

If we multiply two exponential expressions with the same base, then we add the exponents.

The base for each is 5. The exponents 4 and -7 add to -3.

This means

5^4*5^{-7} = 5^{4+(-7)} = 5^{-3}

To convert to a positive exponent, we apply the reciprocal to the base. We go from 5, aka 5/1, to 1/5.

So, 5^{-3} = \left(\frac{1}{5}\right)^3 = \frac{1^3}{5^3} = \frac{1}{5^3}
