A park maintenance person stands 16m from a circular monument. Assume that her lines of sight from tangents to the monument and make an angle of 47 what is the measure of the arc of the monument that her lines of sight intersect?
A) 23. 5
B) 94
C) 266
D) 133
Answer:
D 133 degrees
Step-by-step explanation:
The measure of an angle external to a circle = the difference of the two arcs intercepted divided by 2
47 = [ (360 - x) - x ] / 2
94 = 360 - 2x
x = 133 degrees of the arc

In how many distinguishable ways can the letters of the word ILLINOIS
be ordered?
Answer:
3360 ways
Step-by-step explanation:
ABCDEFGH-- there are 8! ways to organize these letters
since the I is repeated 3 times and the L is repeated 2 times we have to divide by (3!*2!)
[tex]\frac{8!}{2!3!}[/tex]=3360
3360
Answer:
7
Step-by-step explanation:
Since the two L’s must be consecutive, we consider them to be a single letter LL. Then the word ILLINOIS has n = 7 letters: 3 I’s, 1 LL, 1 N, 1 O and 1 S. Hence the numbers of ways to permute letters of the word ILLINOIS if the two L’s must be consecutive is: 7!

Ms. Lance is planning a birthday party. She decided that she
would spend no more than $I20 to buy a cake and balloons.
If the price of the cake is $45 and each balloon costs $15.
how many balloons can she buy?
Need the inequality and equality answer, and final answer
Answer:
The answer is 3
Step-by-step explanation:
You have to subtract 120-45 and that gets you to 75 Then divide 75 by 15 and that gives you 3. So the answer is 3
Answer:
15n + 45 ≤ 120
n ≤ 5
She can buy up to 5 balloons.
Step-by-step explanation:
Fixed amount: $45
Amount per balloon: $15
Let n = number of balloons
Total expense: maximum of $120, which means less than or wequal to $120
15n + 45 ≤ 120
15n ≤ 75
n ≤ 5
She can buy up to 5 balloons.

Grayson was given a large box of 42 chocolates for his birthday. If he eats exactly 2 chocolates each day, how many chocolates would Grayson have remaining 15 days after his birthday?
Answer:
12
Step-by-step explanation:
Let's write this in ratio form.
Days : Chocolates
1 : 2
15 : 30
So, he would eat 30 chocolates in 15 days. To find the remaining ones, we will subtract from the total of the chocolates given.
Chocolates = 42 - 30
= 12
Christina also plans on leaving her $10,000 invested for 20 years. Write an equation representing her investment’s value, y, after x years. What is the value of Christina’s investment after 20 years?
The required equation is y = 10000(1.0.25)^2x. The value of Christina’s investment after 20 years is $30,773.14
Compound interest
The interest accrued on a sum of money is known as interest. The formula for calculating the compound interest is expressed as:
y = y0(1+r/n)^nx
where
x is the time taken
r is the rate in decimal
n is the compounding time
Given the following
x = 20 years
n 2(semi annually)
r = 5.7% = 0.057
Substitute
y = 10000(1+0.057/2)^2(20)
y = 10,000(1 + 0.0285)^40
y = 10000(1.0285)^40
y = 30,773.14
Hence the value of Christina’s investment after 20 years is $30,773.14

Answer:
The flight was 137.45 miles farther than the direct path.
(make slight changes if directions were given on how to round. This is to the nearest hundredth)
Step-by-step explanation:
Use the Law of Cosines.
c^2=
a^2+b^2-2abcosC
You know two sides and the angle in between. The Law of Cosines will give us the third side.
The third side is the direct path of the airplane. We'll add the two other given sides to find the detour route that they took instead.
Then subtract the smaller number (direct route) from the actual route. See image.

The measure of each smaller each angle is 30 degrees.
We have given that,
Oliver draws a straight angle, and then two rays to divide the angle into 3 equal parts.
What is the measure of the straight angle?The measure of the straight angle is 90 degrees.
Therefore we get a straight angle is 90 degrees.
we have to divide the straight angle into 3 equal parts.

A triangle has side lengths measuring 2x 2 ft, x 3 ft, and n ft. which expression represents the possible values of n, in feet? express your answer in simplest terms. x – 1 < n < 3x 5 n = 3x 5 n = x – 1 3x 5 < n < x – 1
The expression x – 1 < n < 3x + 5 represents the possible values of n, in feet whose side lengths are (2x+2) ft, (x+3) ft, and n ft.
What is the triangle?The triangle can be defined as a three-sided polygon in geometry, and it consists of three vertices and three edges. The sum of all the angles inside the triangle is 180°.
We have a triangle whose side lengths measures are (2x+2) ft, (x+3) ft, and n ft.
If we take the first two sides are (2x+2) ft, (x+3) ft, and third is n ft.
By the triangle property, that sum of the two sides is always greater than the third side.
2x+2+x+3 > n
3x+5 > n .....(1)
Now take first two sides as n ft, (x+3) ft, and third side (2x+2) ft
n+x+3 > 2x+2
n > x-1 .....(2)
From the inequality (1) and (2), we get:
x – 1 < n < 3x + 5
Thus, the expression x – 1 < n < 3x + 5 represents the possible values of n, in feet whose side lengths are (2x+2) ft, (x+3) ft, and n ft.
