Miles has a piece of paper that is 1/4 of a large circle.He cuts the paper into five equal parts from the center point of the circle. What is the angel measure of each part?
Answer:
18°
Step-by-step explanation:
First, we find the angle of the large piece of paper that is 1/4 of a circle.
The angle in a circle is 360°. The angle in 1/4 of a circle is:
1/4 * 360 = 90°
He cuts the paper into five equal parts from the center point of the circle. That means the angle was divided into 5 parts:
1/5 * 90 = 18°
Each part has an angle of 18°,
Answer: it's 18
Step-by-step explanation: 18 is the answer hope this helps

Find the area of the irregular polygon, pls hurry I need this quickkkkkk
A: 96 in2
B: 120 in2
C: 80 in2
D: 154 in2
Answer:
To find the area of an irregular polygon you must first separate the shape into regular polygons, or plane shapes. You then use the regular polygon area formulas to find the area of each of those polygons. The last step is to add all those areas together to get the total area of the irregular polygon

Monica deposited $760 into an ordinary annuity after each quarter for 2 years at 4% interest compounded quarterly. Determine the (a) future value of each account and (b) the total interest amount earned.
Answer:
FV=$823.004
Total interest earned=$63.004
Step-by-step explanation:
FV=PV×(1+i/n)^nt
PV=$760
I=4%
t=2 years
n=4
FV=760+(1+0.04/4)^4*2
=760+(1+0.01)^8
=760+(1.01)^8
=760+(1.0829)
=823.004
FV=$823.004
Total interest amount earned
=FV-PV
=$823.004-760
=$63.004

Solve the equation below. 29 11 7 5
Answer:
x = 11
Step-by-step explanation:
Take the fifth root on both sides.
27(x-2) = 3^5
27x-54 = 3^5
27x = 243 + 54
27x = 297
x = 297/27
x = 11
Answer:
[tex]x = 11 \\ [/tex]
Step-by-step explanation:
[tex] \sqrt[5]{27(x - 2)} = 3 \\ { (\sqrt[5]{27(x - 2} )}^{5} = {3}^{5} \\ 27(x - 2) = 243 \\ 27x - 54 = 243 \\ 27x = 243 + 54 \\ 27x = 297 \\ \frac{27x}{27} = \frac{297}{27} \\ x = 11[/tex]

Step-by-step explanation:
On a multiple-choice test, each question has 4 possible answers. A student does not know the answers to three questions, so the student guesses. What is the probability that the student gets all three questions wrong? The probability that the student gets all three questions wrong is . What is the probability that the student gets all three questions right? The probability that the student gets all three questions right is .
Answer:
P(making 3 wrong guesses) = 27/64
P(making 3 right guesses) = 1/64
Step-by-step explanation:
Number of possible answers per question = 4
Number of right answer per question = 1
Number of wrong answers per question = (4 - 1) = 3
Probability = (Number of required outcomes / Number of Total possible outcomes)
A.) probability of guess 3 questions wrong :
Probability of making a wrong guess = (number of wrong options / total number of options
P(making a wrong guess) = 3/4
Therefore,
P(making 3 wrong guesses) = 3/4 × 3/4 × 3/4 = (27/64)
B.) probability of making 3 right guesses:
P(making a right guess) = (number of right options per question / total number of options per question)
P(making a right guess) = 1/4
P(making 3 right guesses) =(1/4 × 1/4 × 1/4) = 1/64
which number line represents the solution set for the inequality 3(8 - 4x) < 6(x - 5 )
Answer:
3 <x
Step-by-step explanation:
3(8 - 4x) < 6(x - 5 )
Divide each side by 3
3/3(8 - 4x) < 6/3(x - 5 )
8 -4x < 2(x-5)
Distribute
8 -4x < 2x-10
Add 4x to each side
8 -4x+4x < 2x+4x-10
8 < 6x-10
Add 10
8+10< 6x-10+10
18<6x
Divide by 6
18/6 < 6x/6
3 <x
Start by distributing on both sides of this inequality.
This gives you 24 - 12x < 6x - 30.
Put your x's together on the left by subtracting 6x from both sides.
This gives you 24 - 18x < -30.
Now subtract 24 from both sides to get -18x < -54.
Now divide both sides by -18 and x > 3.
Remember to switch the direction of the inequality sign
when you divide both sides by a negative number.

when 5 is added to a certain number and the result is multiplied by 3, the final answer is 27. What is the original number
Answer:
Let the number be x
5 is subtracted from a certain number means it will be x - 5
The result is multiplied by 7, the final result is 63,
7 (x - 5) = 63
7x - 35 = 63
7x = 63 + 35
7x = 98
x = 98/7
x = 14
The number is 14
Answer the number is 14 and the equation is 7 (x - 5) = 63
Step-by-step explanation:
Using the appropriate arithmetic operation, the value of the original number is 4
Let the number be : p
5 added to p :
5 + pMultiply the addition by 7 :
(5 + p) × 3 = 27We can solve for p thus :
15 + 3p = 27
3p = 27 - 15
3p = 12
p = 12/3
p = 4
Therefore, the original number is 4.

When the county fair opened its gates, 68 people entered the fairgrounds. After one hour, there were 1.5 times as many people on the fairgrounds as when the gates opened. After two hours, there were 1.5 times as many people on the fairgrounds as the previous hour. If this pattern continues, write the equation representing the number of people, y, at the fair x hours after the gates open.
Answer:
y=1.5x + 68
Step-by-step explanation:
68 is the starting value and it increases by 1.5 every hour.
Answer:
y = 68 ( 1.5) ^x
Step-by-step explanation:
This is exponential growth
The formula is
y = ab^x where a is the initial amount and b is the growth rate
The initial amount is 68 and the growth rate is 1.5
y = 68 ( 1.5) ^x

QUESTION 5 of 10: You are considering selling your home. You consult with an agent who gives you the asking prices of five homes (comps)
in your area: $165,000, $188,000, $175,000, $150,000 and $400,000. The $400,000 is an outlier so you will not include it in your evaluation. In
determining a reasonable asking price, what is the mean of the four remaining comps?
a) $188,000
b) $215,000
Oc) $169,500
d) $175,000
Answer: $169,500
Step-by-step explanation:
The mean simply means the average price of a set of a numbers that are given. For one t calculate the mean, one has to add the numbers that are given and then divide them by the amount of numbers.
I'm the case above, the numbers given are $165,000, $188,000, $175,000, and $150,000.
