Interior angle is (12x+12)°.
The exterior angle is (5x+15)°
how many sides does the polygon have?
Answer:
6 sides
Step-by-step explanation:
The interior angle and exterior angle sum to 180° , then
12x + 12 + 5x + 15 = 180
17x + 27 = 180 ( subtract 27 from both sides )
17x = 153 ( divide both sides by 17 )
x = 9
Then
exterior angle = 5x + 15 = 5(9) + 15 = 45 + 15 = 60°
The sum of the exterior angles of a polygon = 360° , thus number of sides n is
n = 360° ÷ 60° = 6
Find the value of x- plz helppp mee
Answer:
67.5
Step-by-step explanation:
Im pretty sure this is the answer. A triangle is 180º so you do 180-45 and divide it by 2.
Answer:
67.5°
Step-by-step explanation:
The given angle is 45°, so the remaining to angles must collectively make up the rest of the 180°. In this situation, the opposite sides are congruent, and therefore the angles are identical. So, from the remaining 135° that need to be accounted for, we would simply divide by 2, and get 67.5°.

Answer:
A. C. and D.Step-by-step explanation:
Now I can not be 100% sure since I can not see the chart, but I can go off of logic. So let´s get started
First we can eliminate answer B. Answer B does not make ANY sense. Why would the number 3 make a difference.
Now answer A and D. These answers are basically the same. So if one is true, the other is as well. For D, if it were the same number, just negative and positive, the sum would be 0.
So this makes A and D true
Answer C is backed up by answer D as well. They can only be the same distance if one is positive and the other is negative

The radioactive substance polonium-210, with a half-life of 138.39 days, is present in tobacco. Suppose that the soot in an ex-smoker's lungs contains 100 milligrams of polonium-210. How much radioactive polonium will remain after one year of not smoking
Answer:
16.07 milligrams
Step-by-step explanation:
From the question,
Using the formula of radioactive decay,
R/R' = 2ᵃ/ᵇ..................... Equation 1
Where R = Original mass of the polonium-210, R' = Final mass of polonium-210 after decaying, a = Total disintegration time, b = half life of polonium-210.
Make R' the subject of the equation
R' = R/(2ᵃ/ᵇ)................ Equation 2
Given: R = 100 milligrams, a = 1 years = 365 days, b = 138.39 days
Substitute these values into equation 2
R' = 100/(2³⁶⁵⁰⁰/¹³⁸³⁹)
R' = 100/(6.222)
R' = 16.07 milligrams of plonium-210

How do I solve this arithmetic sequence?
Answer:
The 16ᵗʰ term of this sequence is 82
Step-by-step explanation:
Here,
First Term = a₁ = 9
Common Difference = (d) = 2
Now, For 16ᵗʰ term, n = 16
aₙ = a + (n - 1)d
a₁₆ = 7 + (16 - 1) × 2
a₁₆ = 7 + 15 × 5
a₁₆ = 7 + 75
a₁₆ = 82
Thus, The 16ᵗʰ term of this sequence is 82

Q.Given that 4a:3=8:2.Find a.
Answer:
4a:3=8:2
so we multiply 4a to 2 equal to 8 times 3
4a×2=8×3
so a=3
Answer:
a = 3
Step-by-step explanation:
Express the ratios in fractional form , that is
[tex]\frac{4a}{3}[/tex] = [tex]\frac{8}{2}[/tex] ( cross- multiply )
8a = 24 ( divide both sides by 8 )
a = 3

Bobby is 28cm shorter than Daniel. Roy is 19 cm taller than Daniel. Find the difference in height between Roy and Bobby.
Answer:
There is a 47cm difference between the two....
So you just added 28cm to 19cm to get 47cm....
Because 19-(-28) is 19 + 28.

The scale of scores for an IQ test are approximately normal with mean 100 and standard deviation 15. The organization MENSA, which calls itself the “high IQ society”, requires a score of 130 or higher. What percent of adults are between IQ of 100 and 130 ?
A)68%
B)47.5%
C)95%
D)81.5%
Answer:
B) 47.5%
Step-by-step explanation:
Refer to the normal distribution chart attached. If 130 is 2 standard deviations higher than the mean (ignore the numbers beneath the percentages), then by the empirical rule, this means that 34%+13.5%=47.5% of adults are between IQs of 100 and 130. Therefore, option B is correct.
A teacher's grades are normally distributed with a mean of 75 and a standard deviation
of 8.6. What is the probability that a student will score between 56 and 72?
Answer:
34.9%
Step-by-step explanation:
Z1=[tex]\frac{56-75}{8.6}[/tex] = -2.21
F(Z1) = 0.9861
Z2=[tex]\frac{72-75}{8.6}[/tex] = -0.35
F(Z2) = 0.6367
P(56<X<72)= 0.9862-0.6367= 0.349 = 34.9%
Peter has a coupon for 15% off the price of any item in a sporting good store he wants to buy a pair of sneakers that are priced at $36.99 about how much will it take sneakers cost after the discount
Answer:
$31.44
Step-by-step explanation:
According to the word problem, Peter has a coupon for 15% OFF.
This means the price will reduce by 15%.
To solve this, first, change the percentage (15%) to decimal form.
To do this, divide the percentage by 100.
15 / 100 = 0.15.
0.15 is the decimal form of 15%.
Next, multiply the decimal form of the percentage by the price.
36.99 x 0.15 = 5.5485
Lastly, subtract the product from the original price.
36.99 - 5.5485 = 31.4415
In this case, the product goes above the hundredths place.
So we must round 31.4415 to the hundredths place.
31.4415 ≈ 31.44
Therefore, the sneakers are $31.44 after the discount of 15%.
How many times as great as 6 x 10^4 is 3 x 10^7? Enter the answer in the box.
Answer:
5 * 10^2 times greater
Step-by-step explanation:
Here , we want to know how many times bigger is a certain number relative to another
What we have to do here is to make a division
We will have to divide (3 * 10^7) by (6 * 10^4)
That is;
(3 * 10^7) / (6 * 10^4) = 0.5 * 10^7/10^4
= 0.5 * 10^3 = 5 * 10^2

Triangle BCD is similar to triangle FHE. Write at least three equivalent
ratios based on the diagram.
Answer:
CB : HF
CA : HG
CD : HE
DA : EG
DB : EF
AB : GF
If the Triangle BCD is similar to triangle FHE. The three equivalent ratios based on the diagram will be CB: HF, CA: HG, and CD: HE.
What is the triangle?In terms of geometry, a triangle is a three-sided polygon with three edges and three vertices. The triangle's interior angles add up to 180°.
The similarity law for triangles is defined as the law to prove that two triangles have the same shape, but it is not compulsory to have the same size. The ratio of the corresponding sides is in the same proportions and the corresponding angles are congruent.
The equivalent ratios are based on the diagram will be,
CB: HF
CA: HG
CD: HE
DA: EG
DB: EF
AB: GF
Thus, if the Triangle BCD is similar to triangle FHE. The three equivalent ratios based on the diagram will be CB: HF, CA: HG, and CD: HE.

The formula F=1.8C+32 can be used to convert temperature units. F is degrees Fahrenheit, and C is degrees Celsius.
Answer:
-40 °F = -40 °C
Step-by-step explanation:
The formula F = 1.8C + 32 gives the temperature in degrees Fahrenheit (F) for a given temperature in degrees Celsius (C). There is one temperature for which the number of degrees Fahrenheit is equal to the number of degrees Celsius. Complete the equation you can solve to find that temperature and then use it to find the temperature. Use the variable C to represent the number of degrees Celsius where degrees Fahrenheit and degrees Celsius are the same. The equation is . The temperature for which the number of degrees Fahrenheit is equal to the number of degrees Celsius is °C.
F = 1.8 C + 32 (1)
There is one temperature for which the number of degrees Fahrenheit is equal to the number of degrees Celsius
Then,
F = C (2)
Substitute (2) into (1)
F = 1.8 C + 32 (1)
C = 1.8C + 32
Subtract 1.8C from each side
C – 1.8 C = 32
-0.8C = 32
Divide both sides by -0.8
C = 32 / -0.8
C = -40
Substitute C = -40 into (1)
F = 1.8C + 32 (1)
F = 1.8(-40) + 32
F = -72 + 32
F = -40
Therefore,
The temperature for which the number of degrees Fahrenheit is equal to the number of degrees Celsius is -40
That is,
-40 °F = -40 °C

The prom committee is buying Brownies and Cookies. Brownies cost $2 each and Cookies cost $1.50. They need 45 treats and have $82.50 to spend. How many of each should they buy? You need Variables, Equation, and have to explain the solution
Answer:
Number of brownies = 30
Number of cookies = 15
Step-by-step explanation:
Given:
Cost of each brownie = $2
Cost of each cookie = $1.5
Total number of treats = 45
Total amount = $82.50
Find:
Number of cookies and brownie
Computation:
Assume;
Number of brownies = b
Number of cookies = c
So,
b + c = 45........eq1
2b + 1.5c = 82.50...........eq2
Eq1 x 2
2b + 2c = 90 ..................eq3
Eq 3 - Eq 1
0.5c = 7.5
c = 7.5 / 0.5
Number of cookies = 15
Number of brownies = 45 - Number of cookies
Number of brownies = 45 - 15
Number of brownies = 30
A pet store donated a percent of every sale to hospitals. The total sales were $8,900 so they store donated $178. What percent of $8,900 was donated to hospitals?
Answer:
2%
Step-by-step explanation:
Given data
Sales = $8,900
Donated amount= $178
Percentage of donated sales= Donated amount/ Sales*100
Percentage of donated sales= 178/ 8900*100
Percentage of donated sales=0.02*100
Percentage of donated sales=2%
Hence the percentage is 2%
