Answer:
A. 312
Step-by-step explanation:
For the rectangle center multiply 6*4=24
Area of a trapezoid: ((a+b)/2)h so with this we can determine that the area of one side is 40, since there are 2 sides the area would be 80 total
24+80=104
For 3 bows: 104*3=312
<span>SALES: 5x² + 2x – 80
</span>- COST: 5x² – x + 100
= ------------------
PROFIT: 0x²+3x-180
(+3x because we subtracted a negative (-x), which is called adding, similarly taking away 100 from negative 80 is -180.)
Checking:
5x² + 2x – 80
5(500)²+2(500)-80 = 1,250,920
5x² – x + 100
5(500)² – (500) + 100= 1,249,600
Profit = 1,250,920 - 1,249,600 = 1,320
0(500)²+3(500)-180 = 1,320 YAY! {:-)
Double Checking:
5x² + 2x – 80
5(5000)²+2(5000)-80 = 125,009,920
5x² – x + 100
5(5000)² – (5000) + 100= 124,995,100
Profit = 125,009,920 - 124,995,100 = 14,820
0(5000)²+3(5000)-180 = <span>14,820</span> YAY! {:-)

Answer:
They can afford 4 toppings, 2 per pizza.
Step-by-step explanation:
Budget: $33
Per pizza: $12
Per topping: $2
$12 * 2 = $24
$24 in large pizzas with no toppings.
$33 - $24 = $9
They have $9 to spare for toppings.
Each topping is $2.
$9 ÷ $2 = 4.5 (4)
Each pizza can have 2 toppings.
Well, since each doll hair is 22cm, and she had a total of 165cm.
Then number of dolls would be = 165/22 = 7.5
The actual number of dolls = 7. We would drop the .5.
7, Seven.
