Answer:
a, c
Step-by-step explanation:
Let's start with one of each choice. That'll be 3 * 4 * 3 * 3 * 10 = 1080 pizzas. As for the second one, this time the toppings won't be 10 it will be 10 * 9 * 8 because we have 10, and then 9, and then 8 topping choices. This gives us 1080 * 9 * 8 = 77,760. Hope this helps!
Answer:
Option C
The Area Of Shaded Region is 50.2 cm²
Step-by-step explanation:
For A given Circle,
<u>For</u><u> </u><u>Small</u><u> </u><u>(</u><u>Non-Shaded</u><u>)</u><u> </u><u>Circle</u><u>:</u>
Diameter (d) = 6 cm
Radius = d ÷ 2 = 6/2 = 3 cm
For Area of Small (Non-Shaded) Circle
<h3>
<u>Formula</u><u>:</u></h3>
<u>A = πr²</u>
A = 3.14 × (3)² cm
A = 3.14 × 9 cm
A = 28.26 cm²
<u>For </u><u>A</u><u>r</u><u>e</u><u>a</u><u> </u><u>of</u><u> </u><u>Big</u><u> (</u><u>S</u><u>haded) Circle:</u>
Diameter (d) = 10 cm
Radius = d ÷ 2 = 10/2 = 5 cm
For Area of Small (Non-Shaded) Circle
<h3><u>Formula:</u></h3>
<u>A = πr²</u>
A = 3.14 × (5)² cm
A = 3.14 × 25 cm
A = 78.5 cm²
<u>For</u><u> </u><u>The</u><u> </u><u>Area</u><u> </u><u>Of</u><u> </u><u>Shaded</u><u> </u><u>Region</u>
Area of Big Circle - Area of Small Circle
78.5 cm² - 28.26 cm² = 50.24 cm²
Thus, The Area Of Shaded Region is
50.2 cm²

Answer:
The coefficient of x is 22.
X represent the number of laps Marcy swam, 1 1/4x represent the number of times Toni swam.
20 + 0.80(1 1/4x) + 15 + 0.85x = 257
20 + x + 15 + 0.85x = 257
1.85x + 35 = 257
Required equation is 1.85x + 35 = 257
