The arcs FA, AB, and BF make up the entire circle, so their measures sum to 360°:
arcFA + arcAB + arcBF = 360° → arcBF = 360° - 160° - 140° = 60°
By the inscribed angle theorem, angle BAF has measure equal to half of that of arc BF, so
angleBAF = 30°
By the secant-tangent theorem (not sure if there's an official name for it), the measure of angle ACF is equal to half the difference of the arcs it intercepts, namely BF and FA, so that
angleACF = 1/2 (arcFA - arcBF) = 1/2 (160° - 60°) = 50°
Now use the law of sines for solve for FA:
sin(angleACF) / FA = sin(angleBAF) / FC
sin(50°) / FA = sin(30°) / 10
FA = 10 sin(50°) / sin(30°) ≈ 15.3

The length of one wall in Mr. Shelby‘s classroom and 29 feet. What is the length of this wall in inches.
Answers
Answer:
348 inches
Step-by-step explanation:
29x12=348
The length of Mr. Shelby's wall is 348 inches.
What is unit conversion?A unit conversion expresses the same property as a different unit of measurement. For instance, time can be expressed in minutes instead of hours, while distance can be converted from miles to kilometers, or feet, or any other measure of length.
Given that, the length of one wall in Mr. Shelby's classroom and 29 feet, we need to convert it into inches.
So,
1 ft = 12 inches
Therefore,
29 ft = 29 × 12
= 348 inches
Hence, the length of Mr. Shelby's wall is 348 inches.

The solution to the system of equations is (2,9)
The system of equations is given as:

y = 4x + 1
Start by plotting the graphs of 3x - 2y = -12 and y = 4x + 1
From the graph (see attachment), the point of intersection of both lines is:

Cindy’s square-shaped garden has side lengths of x ft. She will plant 5 tulip bulbs per square foot. How many bulbs will she plant if the garden has a side length of 8 feet?
Enter your answer in the box.
Answers
Answer:
The number of bulbs planted in the garden having side length of 8 feet is 320.
Step-by-step explanation:
Given as :
The side length of square shaped garden = x ft
The number of tulip bulbs Cindy's will plant at per square foot = n = 5
Let The number of bulb to be panted for side length of garden = L = 8 feet
Now, According to question
Since the garden is of square shaped ,
So, The area of garden = area of square = side²
I,e The area of garden = x × x ft²
Now, if the side length = L = 8 feet
So, The area of garden = L × L ft²
I.e The area of garden = 8 × 8 ft² = 64 square feet
Now, Again
∵ For the area of 1 square feet , the number of bulbs planted = 5
∴ For the area of 64 square feet , the number of bulbs planted = 5 × 64
I.e For the area of 64 square feet , the number of bulbs planted = 320
Hence The number of bulbs planted in the garden having side length of 8 feet is 320 . Answer

Answers
Answer:
A = 22.5 ft^2
Step-by-step explanation:
This shape is a rectangle of length 30' and width 3/4'.
The area of a rectangle of length L and width W is A = L * W.

Domain = {0,1,2,3} Range = {6,9,12,15}
Step-by-step explanation:
The domain is all of your x values, also known as the input
The range is all of your y values, also known as the output
Just think of the letters dmx - so the domain is x, so y is the range
Range = {6,9,12,15}
Another way to identify the domain and range of functions is by using graphs. Domain refers to the set of possible input values. Domain of a graph consists of all the input values shown on the x-axis. Range is the set of possible output values, which are shown on the y-axis.

ΔABD is similar to ΔBCD.
This means,
The corresponding sides ratio is equal.
AB/BC = BD/CD = AD/BD
AB/m = BD/7 = 11/BD
Now,
BD/7 = 11/BD
BD² = 77
BD = √77
Now,
ΔBDC
BC² = CD² + BD²
m² = 7² + 77
m² = 49 + 77
m² = 126
m = √126
Thus,
The value of m in the figure is √126.
