One circle has a diameter of 6 inches. A second, larger circle has a diameter that is four times the diameter of the first circl
Igoryamba
The area of a circle:
A=\pi r^2
r - the radius, which is equal to half the diameter d

The first circle:
d_1=6 \\&#10;r_1=\frac{6}{2} = 3 \\&#10;A_1=\pi \times 3^2=9\pi

The second circle:
the second circle has a diameter that is four times the diameter of the first circle.
d_2=6 \times 4=24 \\&#10;r_2=\frac{24}{2}=12 \\&#10;A_2=\pi \times 12^2 = 144\pi

The ratio of the area of the smaller cirlce to the area of the larger circle:
\frac{A_1}{A_2}=\frac{9 \pi}{144 \pi}=\frac{9}{144}=\frac{9 \div 9}{144 \div 9}=\frac{1}{16}

The ratio is 1:16.

A store is having a sale on walnuts and chocolate chips. For 8 pounds of walnuts and 4 pounds of chocolate chips, the total cost
astra-53 [7]

Answer:

x = $3.50; y = $2.25

Step-by-step explanation:

First, come up with your two equations where x= price of walnuts and y= price of chocolate chips: 8x + 4y = 37 and 3x + 2y = 15. Solve the first equation.

3x + 2y = 15

3x = 15 - 2y

x = (15 - 2y)/3

Plug in the answer to your second equation.

8(15 - 2y)/3 + 4y = 37

(120 - 16y)/3 + 4y = 37

120 - 16y + 12y = 111

120 - 4y = 111

-4y = -9

y = 2.25

Plug in your answer to find <em>x.</em>

3x + 2(2.25) = 15

3x + 4.5 = 15

3x = 10.5

x = 3.5

Check your equation.

1) 3(3.5) + 2(2.25) = 15

10.5 + 4.5 = 15

15 = 15

2) 8(3.5) + 4(2.25) = 37

28 + 9 = 37

37 = 37
