<h3>Given:</h3>
  • Radius of 50 point region= 3 in
  • Width of other regions= 4 in
<h3>To find:</h3>

The area of the target which earns 30 points on a throw.

<h3>Solution:</h3>

\huge\boxed{Formula: a= \pi{r}^{2}}

4+3

=7

Let's solve

We have to find the answer in terms of π so, we'll just have to multiply the radius by itself.

a={7}^{2}

\large\boxed{a= 49 \pi\: {in}^{2}}

<u>Hence,</u><u> </u><u>the</u><u> </u><u>area</u><u> </u><u>of</u><u> </u><u>the target which earns 30 points on a throw</u><u> </u><u>is</u><u> </u><u>4</u><u>9</u><u>π</u><u> </u><u>square</u><u> </u><u>inches</u><u>.</u>

<u>Answer</u><u>=</u><u> </u><u>Option</u><u> </u><u>B</u>

Which two rooms have an
alexgriva [62]

Answer: room 101 and room 107

Step-by-step explanation:

In room 101, the ratio of boys to girls is 16:12. This is further simplified to its lowest fraction by dividing by 4. It becomes 4:3

In room 104, the ratio of boys to girls is 20:9. This cannot be further simplified to its lowest fraction.

In room 107, the ratio of boys to girls is 12:9. This is further simplified to its lowest fraction by dividing by 3. It becomes 4:3

Therefore, room 101 and room 107 have the same ratio.

The line passes through the points ( 7, -7) and ( 6, -5) a. y = -2x + 7 c. y = -2x - 7 b. y = 2x - 21 d. y = 2x - 7
ollegr [7]
Slope = (-5+7)/(6 - 7) = -2

y = mx + b
b = y - mx
b = -7 - (-2)(7)
b = -7 + 14
b = 7

equation
y = -2x + 7

answer
<span>a. y = -2x + 7</span>
