Answer:
The total cost y of a meal.....
Step-by-step explanation:
The total cost of the meal Y suggests addition, which if you added the x and w portions, you would end up with y.
The other answers suggest subtraction, division, or multiplication, which is not being illustrated by the model.
Answer:
C
Step-by-step explanation:
The solution is the dot where the two equations meet, so that's why I compared them. You can also see it in the graph itself.
Answer:
The scale factor of dilation is 2.
Step-by-step explanation:
From the given information it is notices that the vertices of preimage are A(1, 4), B(3, 4), C(3, 1), and D(1, 1). The vertices of image are A'(2, 8), B'(6, 8), C'(6, 2) and D'(2, 2).
The scale factor is the ratio of distance of a image of a vertex from the center of dilation and distance of the vertex from the center of dilation.
The center of dilation is origin. So, the scale factor is
.... (1)
Distance formula:
Now, put these values in equation (1).
Therefore the scale factor of dilation is 2.

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
