Juan ordered 20 pizzas for a party. 45% of the pizzas have 8 slices each. The remaining 55% of the pizzas have 12 slices each. C

Mama L [17]

Total number of pizzas Juan ordered $20$

Since, $45\%$ of pizzas have $8$ slices.

Therefore, number of pizzas with $8$ slices are: $45\%\times(20)$

$=\frac{45}{100} \times(20)$

$=\frac{45}{10} \times(2)$

$=\frac{90}{10}$

$=9$ pizzas

Also, since, $55\%$ of pizzas have $12$ slices.

Therefore, number of pizzas with $12$ slices are: $55\%\times(20)$

$=\frac{55}{100} \times(20)$

$=\frac{55}{10} \times(2)$

$=\frac{110}{10}$

$=11$ pizzas

Now, there are $9$ pizzas with $8$ slices and $11$ pizzas with $12$ slices.

Therefore, total number of slices of pizza are: $=(9)(8)+(11)(12)$

$=72+132$

$=204$ slices

If g is the inverse of the function f(x) = sqrt(x - 6) - 10 , which of the following is g?

iren2701 [21]

Answer:

g(x) = x² + 20x + 106

Step-by-step explanation:

<u>Given:</u>

$f(x) =\sqrt{x-6}-10$

If g(x) is the inverse of f(x), find it.

<u>Swap x with g(x) and f(x) with x:</u>

$x =\sqrt{g(x)-6}-10$

<u>Solve for g(x):</u>

$x + 10 = \sqrt{g(x)-6}$
$(x+10)^2=g(x)-6$
$g(x) = x^2+20x + 100+6$
$g(x) = x^2+20x + 106$
