Step by step explanation:
1) Semi circle with a diameter equal to the side opposite it, 20 ft.
Find the length of half the circle:
Circumference of semi-circle = (1/2)(πd)
Where:
π = 3.14
d = 20 ft.
Circumference of semi-circle = (1/2)(3.14)(20 ft) = 31.4 ft.
2) Vertical lengths from the endpoint of semi-circle to the endpoints of horizontal lengths, 40 ft each ⇒ 2 × 40 ft. = 80 ft.
3.) Horizontal length at 20 ft.
Add the semi-circle, vertical, and horizontal lengths:
Distance around the pool = 31.4 ft + 80 ft. + 20 ft.
Distance around the pool = 131.4 ft.
No, Brianna is not correct.
The distance around the pool is 131.4 ft
What is perimeter of semicircle?The perimeter of a semicircle is the sum of half of the circumference of the circle and its diameter. As the perimeter of a circle is 2πr or πd. So, the perimeter of a semicircle is 1/2 (πd) + d or πr + 2r, where r is the radius, and, 2r=d is diameter.
P=(πr + 2r)
here, we have,
1) Semi circle with a diameter equal to the side opposite it, 20 ft.
Find the length of half the circle:
Circumference of semi-circle = (1/2)(πd)
Where:
π = 3.14
d = 20 ft.
Circumference of semi-circle = (1/2)(3.14)(20 ft) = 31.4 ft.
2) Vertical lengths from the endpoint of semi-circle to the endpoints of horizontal lengths, 40 ft each ⇒ 2 × 40 ft. = 80 ft.
3.) Horizontal length at 20 ft.
Add the semi-circle, vertical, and horizontal lengths:
Distance around the pool = 31.4 ft + 80 ft. + 20 ft.
Distance around the pool = 131.4 ft.

What is m∠A and what is m∠B?
Answers
Answer:
m∠A = 79°m∠B = 112°Step-by-step explanation:
We have cyclic quadrilateral as all vertexes are on the circle.
As per property of cyclic quadrilateral, each pair of opposite angles are supplementary.
As we know supplementary angles add up to 180°.
m∠A + m∠C = 180° ⇒ m∠A = 180° - 101° = 79°m∠B + m∠D = 180° ⇒m∠B = 180° - 68° = 112°my question is in the image
Answers
Answer:
13.2 miles
Step-by-step explanation:
To solve this, we will need to first solve for the base of the triangle and then use the information we find to solve for the shortest route.
(5.5 + 3.5)² + b² = 15²
9² + b² = 15²
81 + b² = 225
b² = 144
b = 12
Now that we know that the base is 12 miles, we can use that and the 5.5 miles in between Adamsburg and Chenoa to find the shortest route (hypotenuse).
5.5² + 12² = c²
30.25 + 144 = c²
174.25 = c²
13.2 ≈ c
Therefore, the shortest route from Chenoa to Robertsville is about 13.2 miles.

Salesclerks at a store are giving away candles. There are 12 candles on a tray. Three are white and two are red. The rest are green or blue. When choosing a candle at random from the tray, a customer is as likely as not to select a green candle. What tis the likelihood that the customer will select a blue candle? Tell whether it is impossible, unlikely, equally likely as not or certain. Explain your answer.
Answers
Answer:
one blue candle. 1/12 probability.
Step-by-step explanation:
if they are as likely as not to select a green candle, then there are 6 green ones. so now we have accounted for 11 if I am right, so only one can be blue
It is equally likely as not that the customer will select a blue candle.
What is probability?It is the chance of an event to occur from a total number of outcomes.
The formula for probability is given as:
Probability = Number of required events / Total number of outcomes.
Example:
The probability of getting a head in tossing a coin.
P(H) = 1/2
We have,
Let the number of green candles on the tray be G, and the number of blue candles be B.
We know that there are 12 candles in total on the tray, so:
G + B = 12 (total number of green and blue candles is 12)
G/(G+B) = 1/2 (as the probability of selecting a green candle is equal to the probability of selecting a non-green candle)
We can use these two equations to solve for G and B:
G + B = 12
G = (12 - B)
Substituting into the second equation:
(12 - B) / (12 - B + B) = 1/2
(12 - B) / 12 = 1/2
12 - B = 6
B = 6
So there are 6 blue candles on the tray.
Since there are 12 candles in total, and 6 of them are blue, the probability of selecting a blue candle at random is:
P(selecting blue) = B / (G + B) = 6 / 12 = 1/2
Therefore,
It is equally likely as not that the customer will select a blue candle.
This means that the probability of selecting a blue candle is 50-50, which is neither impossible nor certain, but rather equally likely as selecting a green candle.
