Answer:
35.34
Step-by-step explanation:
The formula for arc length is 2rФπ/360
2(15)(135)=4050
4050/360·π=35.34
Please don't say something random just for the points this is my last question on my test and I would really appreciate it if I could get the right answer not a, I think, or sorry if I'm wrong thank you, Lilly records the age, in years, and the height, in inches, of the starting players on the girls’ middle school basketball team.
She records them as ordered pairs (age, height): (11, 62), (12, 64), (13, 65), (13, 67), and (14, 68).
Is this relation a function? Explain.
Answer: C because there are two ages with 13 as an x value, making it a relation not a function.
Question Help
Think About the Process A jar contains only pennies, nickels, dimes, and quarters. There are 29
pennies, 16 dimes, and 17 quarters. The rest of the coins are nickels. There are 74 coins in all. How
many of the coins are not nickels? If n represents the number of nickels in the jar, what equation could
you use to find n?
Answer:
62 coins are not nickels. you could just add the pennies, dimes, & quarters. those totals are given. So
29+16+17= 62
or if you want to impress then start with the total and subtract each given coin count
74-29-16-17=12
74-12=62

A set of biology exam scores are normally distributed with a mean of 70 points and a standard deviation of six points X equal the score on a randomly selected exam from the set find P(X< 73)
Answer: .69
Step-by-step explanation:
Answer on khan
We can write the value in the range P(64 < {x} < 76) as 0.68.
What is standard deviation?In statistics, the standard deviation is a measure of the amount of variation or dispersion of a set of values.
Given is that a set of biology exam scores are normally distributed with a mean of 70 points and a standard deviation of six points X equal the score on a randomly selected exam from the set.
It is given that -
μ = 70
σ = 6
For the range of {x}, we can write -
(μ - σ) < {x} < (μ + σ)
64 < {x} < 76
We can write the range of {z} value as -
(64 - 70)/6 < {z} < (64 + 70)/6
- 1 < {z} < + 1
Now -
P(64 < {x} < 76) = P(x < 76) - P(x < 64) = 0.84 - 0.15 = 0.68
Therefore, we can write the value in the range P(64 < {x} < 76) as 0.68.

Madison has a collection of 220 coins. How many coins represent 5% of her
collection?
Help me please
Answer:
11
220/x=100/5
(220/x)*x=(100/5)*x - we multiply both sides of the equation by x
220=20*x - we divide both sides of the equation by (20) to get x
220/20=x

Find the 9th term of the geometric sequence 9, -27, 81...
Answer:
a9= 59049
Step-by-step explanation:
Find the r.
R= 81/-27
R= -3
a1= 9
a2= -27
a3= 81
a4= 81*-3= -243
a5= -243*-3= 729
a6= 729*-3= -2187
a7= -2187*-3= 6561
a8= 6561*-3= -19683
a9= -19683*-3= 59049

∠A and \angle B∠B are complementary angles. If m\angle A=(2x-10)^{\circ}∠A=(2x−10) ∘ and m\angle B=(x-2)^{\circ}∠B=(x−2) ∘ , then find the measure of \angle A∠A.
Answer:
118°
Step-by-step explanation:
Two angles are called complementary when their measures add to 90 degrees.
From the question,
Angle A=(2x-10)°
Angle B=(x-2)°
Both Angles are complementary.
Therefore
Step 1
(2x - 10)° + (x - 2)° = 180°
2x + x - 10 - 2 = 180°
3x - 12 = 180°
3x = 180° + 12
3x = 192°
x = 192/3
x = 64°
Step 2
We are to solve for Angle A
(2x-10)°
Angle A = 2(64 ) - 10
Angle A = 128 - 10
Angle A = 118°
The measure of Angle A = 118°

It is given that two lines are parallel, and hence the corresponding angles are congruent, by corresponding angles postulate. It is also given that the triangles in the photo share an angle, by the reflexive property, the shared angle is congruent. Hence one can use angle-angle to determine that the two triangles in the picture are similar.
Using this, one can set up a proportion with the sides. The ratios of any two corresponding sides are the same as any other two corresponding sides in the triangle, respectively, this is due to the corresponding parts of similar triangles theorem.
