Answer:

The correct answer is D) (x - 8)^2 + (y - 4)^2 = 16

Step-by-step explanation:

In order to find this, we simply need to use the base form of a circle.

(x - x1)^2 + (y - y1)^2 = r^2

Now we input the values of the vertex and the radius.

(x - 8)^2 + (y - 4)^2 = 4^2

(x - 8)^2 + (y - 4)^2 = 16

Which situation represents a proportional relationship?

Natalka [10]

Answer:

B) Jack biked 5 miles in 25 minutes and 8 miles in 40 minutes.

Step-by-step explanation:

we know that

A relationship between two variables, x, and y, represent a proportional variation if it can be expressed in the form $y=kx$

The ratio between the two variables is a constant called constant of proportionality k

$k=y/x$

<u><em>Verify each case</em></u>

A) Julie sold 4 necklaces for $12 and 9 necklaces for $25.

$\frac{4}{12}=\frac{9}{25}$

Multiply in cross

$4(25)=9(12)\\100\neq108$

Is not true

therefore

The situation not represent a proportional relationship

B) Jack biked 5 miles in 25 minutes and 8 miles in 40 minutes.

$\frac{5}{25}=\frac{8}{40}$

Multiply in cross

$5(40)=8(25)\\200=200$

Is true

therefore

The situation represent a proportional relationship

C) Larry packed 24 apples in 6 boxes and 46 apples in 9 boxes

$\frac{24}{6}=\frac{46}{9}$

Multiply in cross

$24(9)=46(6)\\216\neq276$

Is not true

therefore

The situation not represent a proportional relationship

D) Allie put 14 pieces of candy in 2 bags and 30 pieces of candy in 4 bags

$\frac{14}{2}=\frac{30}{4}$

Multiply in cross

$14(4)=30(2)\\56\neq60$

Is not true

therefore

The situation not represent a proportional relationship

A $230 pair of shoes is on sale for 20% off at a store in Illinois. Sales Tax in Illinois is 11.5%. How Much Will The shoes end

Zepler [3.9K]

FIND SALE PRICE
= $230 - ($230*20%)
= $230 - $46
= $184

OR

= $230 * (100%-20%)
= $230 * 80%
= $184

*use the method you're most comfortable with or that your teachers prefer

FIND TOTAL WITH TAX
= $184 + ($184 * 11.5%)
= $184 + $21.16
= $205.16

ANSWER: The shoes with discount and taxes cost $205.16.

Hope this helps! :)
