Answer:
x = 165°
Step-by-step explanation:
x° = 360 - (the measure of one interior angle of the octagon + the measure of one interior angle of the equilateral ∆)
Each interior angle of a regular octagon = 135° ([tex] \frac{(n - 2)180}{n} = 135°)
An equilateral ∆ has equal angles, each measuring 60°.
Therefore:
x° = 360° - (135° + 60°)
x = 360 - 195
x = 165°
Answer:
165°

vi. Which one of the following is NOT a perfect square?
a. 625
b. 156
c. 196
Answer:
b. 156
Step-by-step explanation:
A "perfect square" is the product of an integer that is being multiplied by itself.
Choice a, 625, is a perfect square because it is the product of 25 multiplied by itself.
25 x 25 = 625Choice b, 156, is not a perfect square because you cannot find any integer that can be multiplied by itself that will result in 156 as a product. Therefore, this is the correct answer.
Choice c, 196, is a perfect square because it is the product of 14 multiplied by itself.
14 x 14 = 196I need help please

During a sale, a store offered a 40% discount on a particular camera that was originally priced at $450. After the sale, the discounted price of the camera was increased by 40%. What was the price of the camera after this increase?
Answer:
378
Step-by-step explanation:
Remark
This is a question that all investors in stocks should be aware off. It does not come back to 450 dollars.
Step One
Find out the price of the discounted camera.
40% reduction price = 450 - (40/100)*450
40% reduction price = 450 - 180 = 270
Step Two
Now add 40% onto the new price.
New price = Reduced price + 40% of reduced price
New Price = 270 + 40%* 270
New Price = 270 + 108
New Price = 378
Remark
The reason stock investors should be aware of this is that if you take a 40% loss on a stock it takes more than a 40% gain to make the price of your stock loss back.

Given parallelogram SNOW, diagonals SO and NW intersect at D.
If SD = 9x+5 and OD = 13X - 3, find the length of SO
Answer:
The length of SO is 46 units
Step-by-step explanation:
In a parallelogram, diagonals bisect each other, which means meet each other in their mid-point
∵ SNOW is a parallelogram
∵ SO and NW are diagonals
∵ SO ∩ NW at point D
→ That means D is the mid-point of SO and NW
∴ D is the mid-point of SO and NW
∵ D is the mid-point of SO
→ That means D divide SO into two equal parts SD and DO
∴ SD = DO
∵ SD = 9x + 5
∵ DO = 13x - 3
→ Equate them
∴ 13x - 3 = 9x + 5
→ Subtract 9x from both sides
∵ 13x - 9x - 3 = 9x - 9x + 5
∴ 4x - 3 = 5
→ Add 3 to both sides
∵ 4x - 3 + 3 = 5 + 3
∴ 4x = 8
→ Divide both sides by 4
∴ x = 2
→ To find the length of SO substitute the value os x in SD and DO
∵ SO = SD + DO
∵ SD = 9(2) + 5 = 18 + 5 = 23
∵ DO = 13(2) - 3 = 26 - 3 = 23
∴ SO = 23 + 23 = 46
∴ The length of SO is 46 units

Adam is a field goal kicker. If he made 30 field goals out of his last 32 attempts, what percent of the attempts did he make?
PLZ HELP I DONT UNDERSTAND
Answer:
62
Step-by-step explanation:
Turn the percentage into a decimal.
50% = 0.5
Divide.
31 / 0.5 = 62
Best of Luck!
Answer:
62
Step-by-step explanation:
50% is technically 1/2 right?
So, if 31 is half of this mysterious number then we just need to times 31 by 2.
Therefore, 31 * 2 = 62.
We can check this by multiplying 62 by .50 (remember that when using percents in an operation we move the decimal over twice)
62 * .50 = 31
I hope this helps!!

A pair of angles is supplementary if the sum of their measures is 180 degrees. A pair of angels is complementary if the sum of their measures 90 degrees. the supplement of a given angel is 10 degrees more than twice its complement. Let 90-x equal the degree measure of its complement and 180-x equal the degree measure of its supplement. Write and solve an equation to find the measure of the given angel.
Answer:
The measure of the complement =
= 80°
The measure of the supplement=
= 170°
Step-by-step explanation:
Let
90-x equal the degree measure of its complement
180-x equal the degree measure of its supplement.
We are told in the question that: the supplement of a given angle is 10 degrees more than twice its complement.
Hence, the Equation is;
(180 - x) = 10° + 2(90 - x)
180 - x = 10 + 180 - 2x
Collect like terms
-x + 2x = 10 + 180 - 180
x = 10°
Hence,
The measure of the complement =
90 - x
= 90 - 10
= 80°
The measure of the supplement=
180 - x
= 180 - 10
= 170°

A car is 170 inches long. A truck is 85% longer than the car.
How long is the truck
Answer:
Step-by-step explanation:
if the car is 170 inches long
the truck is 85% longer
(170*85)/100=144.50 longer
the truck is 170+144.50=314.50
Answer:
314.5 inches100-85=15
170*0.15=25.5
170-25.5=144.5
170+144.5=314.5 inches
After completing the fraction division 5 divided by five-thirds, Miko used the multiplication shown to check her work. 3 times five-thirds = StartFraction 3 Over 1 EndFraction times five-thirds = StartFraction 15 Over 3 EndFraction or 5 Which is the most accurate description of Miko's work? Miko found the correct quotient and checked her work using multiplication correctly. Miko found the correct quotient but checked her work using multiplication incorrectly. Miko found an incorrect quotient but checked her work using multiplication correctly. Miko found an incorrect quotient and checked her work using multiplication incorrectly.
Answer:
Miko found an incorrect quotient and checked her work using multiplication incorrectly.
Step-by-step explanation:
The given expression is
[tex]\dfrac{5}{\dfrac{5}{3}}[/tex]
Applying the reciprocal rule we get
[tex]5\times \dfrac{3}{5}=5[/tex]
What Miko did was
[tex]3\times \dfrac{5}{3}=\dfrac{3}{1}\times\dfrac{5}{3}=\dfrac{15}{3}\ \text{or}\ 5[/tex]
So, Miko took the wrong values of the quotients and applied multiplication incorrectly.
Hence, Miko found an incorrect quotient and checked her work using multiplication incorrectly.

Lucas is walking around the edge of the playground shown. How far will lukas have to walk when he finishes one loop around the playground? Round to the nearest unit, if necessary.
Answer:
See Explanation
Step-by-step explanation:
Required
Determine how far he walked in one loop
This question is incomplete, as the playground diagram and dimensions are missing. However, I'll answer on a general terms.
What this question requires is to calculate the perimeter of the playground.
Assume that the playground is rectangular and the dimensions are: 2 meters by 3 meters.
The distance walked will be calculated using the following perimeter formula.
[tex]Distance = 2(2m + 3m)[/tex]
[tex]Distance = 2(5m)[/tex]
[tex]Distance = 10m[/tex]
If it is a square with 5m as the length of one of its side, the distance would be:
[tex]Distance = 4 * 5m[/tex]
[tex]Distance = 20m[/tex]
So basically, all you need to do is calculate the perimeter of the playground.

12. 4, 0, 2, 1 this for y not x,y
<3
Can i have some help
Answer:
y = -1/3x
Step-by-step explanation:
The slope of that are perpendicular lines are negative opposites of each other. If a line has a slope of 3, then a line perpendicular to it will have a slope of (-(1/3)).
Use the equation of a line in point-slope form to solve this;
y = mx + b
where "m" is the slope and "b" is the y-intercept.
Substitute the slope in;
y = (-1/3)x + b
Since it passes through the origin, then it has no y-intercept, therefore the equation of the line is;
y = -1/3x

Janna and Travon are creating posters for the school play. Together they will have f(t) posters after creating posters for t hours. f(t) = 5t + 3 The function f represents the fact that every hour —
Answer:
8posters are created
Step-by-step explanation:
Given the function that represents the total number of posters expressed as
f(t)= 5t+3
The total posters every hour occur at t = 1hr
Substitute into the equation
f(1) = 5(1)+3
f(1) = 5+3
f(1) = 8
Hence the function f represents the fact that every hour, 8posters are being created
Fred weighs 40 pounds less than twice Barney. Their combined weight is 320 pounds. Let F = Fred's weight in pounds and B = Barney's weight in pounds. Write a system to represent the situation. DO NOT SOLVE.
Answer:
Step-by-step explanation:
Using the information provided we can create two different equations for this system. The first of which would be Fred's overall weight, while the second equation would be Fred's and Barney's combined weight. These equations would be the following...
F = 2B - 40
320 = F + B
As requested I will not solve the system of equations and leave them as they are.
