PLEASE ANSWER ANY PROBLEM ASAP THANK YOU SO MUCH

Answers

Answer:

1) No

2) Yes

3) angle UXS = 120 degrees

4) arc CB = 40 degrees

Step-by-step explanation:

If AB is tangent to the circle, then angle at A would be 90 degrees.

1)

Is 13^2 + 14.6^2 = 19.4^2?

169 + 213.16 = 376.36      No

2)

Is 8^2 + 6^2 = 10^2?

64 + 36 = 100      Yes

3)

arc WS = arc VU + arc TU = 113 degrees

arc ST = arc WV because their chords cross making a pair of vertical angles.

full circle = 360 degrees

360-113 - 113 = 134 degrees

134/2 = 67 degrees for arc ST

arc STU = 67 + 53 = 120 degrees

Angle UXS = 120 degrees

4) arc CB = arc FB =  40 degrees because their chords cross making a pair of vertical angles.

Find the median of 6,2,0,1,1,2,3,2,0,2,3,4,2,3,5

Answers

The median is 2
Median = Middle

First, arrange the numbers from lowest -> highest

This would be:
0, 0, 1, 1, 2, 2, 2, 2, 2, 3, 3, 3, 4, 5, 6

Now, strike off one number from each side (so 0, then 6, then 0, then 5) until you are only left with one or two numbers.

If you are left with one number, that is your median!

If you are left with two numbers, than you add them together, then divide that number by 2 (for example if you were left with 7 and 8, 7+8=15. 15/2=7 1/2)

In this case, you are left with one number, 2, so 2 is your median.
I hope this helped!

Answer:

2

Step-by-step explanation:

The median is the middle number when the numbers are lined up from least to greatest or greatest to least.

First, the numbers must be lined up from least to greatest.

0, 0, 1, 1, 2, 2, 2, 2, 2, 3, 3, 3, 4, 5, 6

Then, find the middle number.

The middle number is 2.

Working together, two pumps can drain a certain pool in 6 hours. If it takes the older pump 15 hours to drain the pool by itself, how pump to drain the pool on its own?

Answers

Answer:

10

Step-by-step explanation:

Rate of drainage for pump A and B = [1 pool drained]/[6 hours]

Rate of drainage for pump A (older pump) = [1 pool drained]/[15 hours]

Rate for pump B (newer pump) = [1 pool drained]/[t hours]

Thus, adding the rate of drainage of A and B,

1/t + 1/15 = 1/6

t=10

plz help, Randy is fencing off a semi-circular region in his backyard against a wall. The semi-circular region has a diameter of 24 feet. The fencing will go along the arc only. How much fencing does Randy need?

Answers

Answer:

[tex]Fence = 41.408ft[/tex]

Step-by-step explanation:

Given

[tex]d = 24ft[/tex]

Required

Determine the length of the wall

First, we calculate the circumference (C) of the semi-circle

[tex]C =\pi d[/tex]

[tex]C = 3.142 * 24[/tex]

[tex]C = 75.408[/tex]

The length of the fence is calculated by subtracting the diameter from the circumference:

[tex]Fence = C - d[/tex]

[tex]Fence = 75.408ft - 24ft[/tex]

[tex]Fence = 41.408ft[/tex]

He wanted to show us that he was the boss here, but we refused to run away in fear. Then the gorilla's behavior changed. He seemed to realize, "These guys are with me now." He led us deep into the forest, pausing from time to time so we could catch up. The jungle growth was thick with thorns and brush.
