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

Answer: The options are kinda weird

But the solution to x - 12.5 = 17 is x = 29.5, so whichever equation you plug this into is correct is the right equation...

Find the area of a trapezoid with bases 2ft and 3ft and height 1/3 foot. Round your answer to the nearest tenth

amid [387]

Answer:

Area = 5/6 of a foot^2

Step-by-step explanation:

Formula

Area of a trapezoid (formula) = 1/2 (b1 + b2)*h/2

Givens

b1 = 2 feet
b2 = 3 feet
h = 1/3 foot

Solution

Area = 1/2(2 + 3)*1/3

Area = 1/2(5)* 1/3

Area = (1/2 * 1/3) * 5

Area = (1/6) * 5

Area = 5/6

Simplify this question please

xeze [42]

I think x = 38 but idk

Don't believe me I might be wrong.

I'm pretty sure you're trying to find what x equals and the other angles ten. fifty-one, and ninety (which equals 142) which goes into x and x is 38 because 142 + 38 = 180 which is complementary.
idek.
