Lucía needs 13.33 feet of cotton.
Since Lucía makes braided key chains out of cotton cord, and for every 8 feet of cotton cord she has, she can make 3 braided key chains, to represent the relationship between the feet of cotton cord and the number of key chains and find the number of feet of cotton cord Lucia needs to make 5 key chains, the following calculations must be performed, through a cross multiplication:
- 8CC = 3KC
- 3 = 8
- 5 = X
- 5 x 8/3 = X
- 40/3 = X
- 13.33 = X
Therefore, Lucía needs 13.33 feet of cotton.

The dot plot shows the frequency or length of the tadpoles
The total length of the tadpoles that are 1/8-inch and 1/4-inch long is 7/8 inches
<h3>How to determine the total length?</h3>
From the dot plot, we have the following parameters:
- 3 tadpoles have a length of 1/8
- 2 tadpoles have a length of 1/4
So, the total length is:
Total = 3 * 1/8 + 2 * 1/4
Evaluate the product
Total = 3/8 + 1/2
Rewrite as;
Total = 3/8 + 4/8
Evaluate the sum
Total = 7/8
Hence, the total length of the tadpoles that are 1/8-inch and 1/4-inch long is 7/8 inches

Answer:
The angle will be "48.7°".
Step-by-step explanation:
In ΔTBO, the given values are:
TB = 6,000 feet
BO = 9,000 feet
Now,
To find the angle,
⇒ 
On putting the estimated values, we get
⇒ 
⇒ 
⇒ 
⇒ 
The shaded area in the image is 86.1 square inches.
<h3>
How to get the shaded area?</h3>
Remember that for a circle of diameter D, the area is given by:
A = pi*(D/2)²
Where pi = 3.14, and here we have half-circles, so we need to add a factor 0.5
The area of the shaded figure, the area of the shaded figure will be the area of the half circle with diameter of 17in minus the area of the half circle with a diameter of 8.5 in, so the area is:
area = 0.5*3.14*(17in/2)² - 0.5*3.14*(8.5in/2)² = 86.1 in²

Answer:
$72.15
Step-by-step explanation:
x= pounds of steak
$
= money spent on steaks
If Neil buys 7.5 pounds of steak then x =7.5
$9.62(7.5) = $72.15
