Kamila has a rectangular lawn that measures 80 by 150 feet. She wants to lay gravel made from colored rock in a border, 6 feet w
Zarrin [17]
Part 1) <span>Create a diagram that shows Kamila’s rectangular lawn and the gravel border. Assign variables to any unknown sides and label the diagram

see the attached figure  

Part 2)</span><span>Use your diagram to determine how many square feet of the gravel border will surround the lawn

area of the border=[162*92]-[150*80]----> 14904-12000-----> 2904 ft</span>²

Part 3) <span>Kamila decided that the depth of the gravel needs to be 2 inches. What is the total volume of gravel needed for the border?

we know that
1 ft-------> 12 in
 x--------> 2 in
x=2/12------> x=0.17 ft

volume of gravel needed=area of the border*deep of the gravel
</span>volume of gravel needed=2904*0.17----> 493.68 ft³
<span>
Part 4)</span><span>A large bag of colored rock contains a cubic yard and costs $30. What is the total cost of the rocks needed for the border?
</span>
1 yd³--------> 27 ft³
x---------> 493.68 ft³
x=493.68/27-----> 18.28 yd³

if 1 yd³----------> cost $30
 18.28 yd³------> x
x=18.28*30------> x=$548.53

the answer Part 4) is 
$548.53

Solve for R using cross multiplication
topjm [15]

R/ r+ 15 = 3/8

Cross multiply: top of one side multiplied by bottom of other side:

R x 8 = 3 x r+ 15

Simplify:

8r = 3r + 45

Subtract 3r from both sides:

5r = 45

Divide both sides by 5:

R = 9

Please help! Would be appreciated so much
Cloud [144]

Answer:

25%.

Step-by-step explanation:

First, let's find the area of both circles. The area of a circle is given by:

\displaystyle A = \pi r^2

The radius of the smaller circle is one. Thus, its area is:

\displaystyle A = \pi (1)^2 = \pi

The radius of the larger circle is two. Thus, its area is:

\displaystyle A = pi (2)^2 = 4\pi

The probability that a random point chosen will be inside the small circle will be the area of the small circle over the total area. Hence:

\displaystyle P= \frac{\pi }{4\pi}=\frac{1}{4}= 25\%

The probability of a random point being in the small circle is 25%.
