What are the angles of a triangle
━━━━━━━━━━━━━━━ ♡ ━━━━━━━━━━━━━━━
The (interior) angles of a triangle always add up to 180 degrees. To find the exterior angles of a triangle, subtract the interior triangle from 360 degrees.
The total degrees of any polygon is (n-2)×180 (n is the number of angles). 3-2 is 1 and 1 times 180 is 180. Therefore, the angles of a triangle always add up to 180 degrees.

Find the value of x.
A.48
B.56
C.68
D.76
Answer:
A
Step-by-step explanation:
The secant- tangent angle 78° is half the difference of the intercepted arcs
[tex]\frac{1}{2}[/tex] (204 - x) = 78 ( multiply both sides by 2 )
204 - x = 156 ( subtract 204 from both sides )
- x = - 48 ( multiply both sides by - 1 )
x = 48

For the transformation T, write the T-1. T: (x, y) ( 2x, y + 5) T -1 (x, y) (x - 2, y - 5) (2x - 1, y + 4) (½x, y - 5)
=====================================
Explanation:
The original transformation (2x, y+5) takes any x value and doubles it. So the inverse of this is to cut the x value in half. We can say x/2 since division is the opposite of multiplication. The value x/2 is the same as ½x
For the y coordinate, we add on 5 for the original transformation. Subtraction undoes addition meaning the inverse will have y-5.
Side note: the inverse notation [tex]T^{-1}[/tex] can be written as T^(-1).

At a benefit concert, 13 bands have volunteered to perform but there is only enough time for eight of the bands to play. How many lineups are possible?
Answer: 51891840
Step-by-step explanation:
Given : Total bands = 13
Possible number of bands can perform= 8
For arranging in order we use permutations.
By using permutations, the number of lineups are possible = [tex]^{13}P_8=\dfrac{13!}{(13-8)!}[/tex]

Answer:
$322000
Step-by-step explanation:
A woman owns the W½ of the NW¼ of the NW¼ of a section.
= 640/2/4/4 = 20 acres
She wants to buy remaining of NW 1/4 = 640/4-20 = 140 acres.
It would cost = 140*2300 = $322000
Therefore, it cost $32000 to purchase the part.
Rearrange the equation so x is the independent variable. y + 6 = 5(x-4)
Answer:
y = 5x- 26
Step-by-step explanation:
x is the independent variable, which means solve for y
y + 6 = 5(x-4)
Distribute
y+6 = 5x -20
Subtract 6 from each side
y+6-6 = 5x -20-6
y = 5x- 26
y = 5x- 26

1) What is the difference between rigid and non rigid motion?
Answer: Rigid motion is otherwise known as a rigid transformation and occurs when a point or object is moved, but the size and shape remain the same. This differs from non-rigid motion, like a dilation, where the size of the object can increase or decrease
Step-by-step explanation:
a can of soup has a volume of 20 pi cubic inches. the diameter of the can is 4 inches. What is the height of the can
Answer:
5 inchesStep-by-step explanation:
A can is cylindrical in nature and volume of a cylinder is expressed as;
V = πr²h where;
r is the radius of the cylindrical can
h is the height of the can.
Given parameters
Volume of the can of soup = 20πin³
diameter of the can = 4inches
Since diameter = 2r
radius = d/2 = 4/2 = 2inches
Required parameter.
Height of the can
Substituting the given parameters into the formula to get the height h will give;
20π = πr²h
20 = r²h
20 = 2²h
20 = 4h
Divide both sides by 4:
4h/4 = 20/4
h = 5inches
Hence the heighr of the can is 5 inches
6. To check whether the rose bush lies on the circle, see if its coordinates make the
equation for the circle true. Show your work (2 points)
Part of question :
(x-10)^2+(y-10)^2=100
(16-10)^2+(18-10)^2=100
Answer:
Yes, equation of circle is true
Step-by-step explanation:
(x-10)^2+(y-10)^2=100
(16-10)^2+(18-10)^2=100
100=100
plugging the coordinates into the equation of the circle, we observe that the equation is true since both sides of the equation are equal(value on both sides of the equal sign are same). This wouldn't be true if for instance the left side of the equation evaluated to ≠100. Therefore we can conclude that the rose bush lies on circle since the equation is true

A bean stalk doubled its height every day. This was a magical bean stalk that grew from
the magical beans that Jack planted, which he got from selling his mother's cow. The bean
stalk reached its full height in 100 days. How many days did it take to reach half its height?
Answer:
The number of days it take to reach half its height is 99 days
Step-by-step explanation:
The given parameters are;
The height to which the beans stalk grew daily = Twice the initial height
The time duration for the bean stalk to reach maximum height = 100 days
Therefore, the growth of the bean stock is in the form of a geometric progression with a common ratio, r = 2
The formula for a geometric progression = a×r⁽ⁿ⁻¹⁾
Therefore, the height of the bean is given by the formula a×r⁽ⁿ⁻¹⁾
Where;
The first term = a = 1 (for analysis)
The number of terms (days) = n = 100 for 100 days
Therefore, we have;
After 100 days, the height of the bean = 1×2⁽¹⁰⁰⁻¹⁾ = 2⁹⁹ = 6.34 × 10²⁹
Half the height = 6.34 × 10²⁹/2 = 3.1291265 × 10²⁹
Which gives;
1×2⁽ⁿ⁻¹⁾ = 3.1291265 × 10²⁹
n - 1 = ㏒(3.1291265 × 10²⁹)/㏒(2) = 98
Which gives;
n - 1 = 98
n = 98 + 1 = 99 days.

If there are 1000 meters in 1 kilometer, and 1 mile equals approximately 1609.34 meters, how many miles will Kyle run in the race? Round your answer to the nearest hundredth place.
Answer:
3.11 miles
Step-by-step explanation:
Hello!
First we have to get the distance into meters
The problem says there are 5 kilometers in a race and 1000 meters in a kilometer so 5 kilometers is 5000 meters
Now we turn the meters into miles
It says a mile is about 1609.34 so we can divide the amount of meters by how many meters are in a mile
5000/1609.34 = 3.106
Round to the nearest tenth
3.106 ⇒ 3.11
The answer is 3.11 miles

overall mean.
a. treatment
b. error
c. interaction
d. total
Answer:
treatment
Step-by-step explanation:
hope this helps, I did OSM 202 MC , as well.
The TREATMENT sum of squares measures the variability of the sample treatment means around the overall mean.
The sum of squares is used to measure the variation about the mean, In ANOVA we have:
• Sum of square Error : measures the variation between each observation in a group and the mean of that group.
• Sum of square treatment : measures the variation between the mean of each group and the overall mean.
• Total Sum of Square : measures the variation between each observation and the overall sample mean.
Hence, Treatment sum of squares measures variation between sample treatment and overall sample mean.

when the number is reduced by 15% , the answer is 6154 . What is the original number ?
Let's assume the number as x .
15% of x = [tex]\dfrac{x \times 15}{100} [/tex]
→ [tex]\dfrac{3x}{20} [/tex]
So after reducing 15% the number will be 6154 .
→ x - 3x/20 = 6154
→ 17x/20 = 6154
→ 17x = 6154 × 20
→ 17x = 123080
→ x = 123080/17
→ x = 7240So the number is 7240

How do I factor e^2-10e+25
Answer: (e-5)^2
Step-by-step explanation:
The box method is a good way to solve this, but for a quick explanation, start by finding a single value that when added gets -10 and when multiplied gets +25. We can find that this term is -5. We the can situate -5 into (e-5)^2 equation, where if you FOIL, you will be back at the unfactored equation. Hope this helps
The factored form of e² - 10e + 25 is (e - 5)².
To factor the expression e² - 10e + 25, we can use the method of recognizing it as a perfect square trinomial. A perfect square trinomial is a quadratic expression of the form (a - b)², where 'a' and 'b' are constants.
In the given expression, e² - 10e + 25, the first term (e²) and the last term (25) are perfect squares, and the middle term (-10e) is twice the product of the square roots of the first and last terms.
So, we can rewrite the expression as:
(e - 5)²
Now, if we expand (e - 5)², we get:
(e - 5)(e - 5) = e² - 10e + 25
Therefore, the factored form of e² - 10e + 25 is (e - 5)².

Company A makes three different group of products, There are liquid products, solid products, and gas products. The ratio of liquid to solid to gas product is 3:4:5. If there are exect;y 36 different solid products, how many total products are there?
Answer: Total products = 108
Step-by-step explanation: Ratio of solid to liquid products is 3:4 and there are 36 solids, so:
[tex]\frac{3}{4} = \frac{Pl}{36}[/tex]
[tex]Pl = \frac{36.3}{4}[/tex]
Pl = 27
Ratio of solid to gas is 4:5:
[tex]\frac{4}{5}=\frac{36}{Pg}[/tex]
[tex]Pg=\frac{36.5}{4}[/tex]
Pg = 45
Total products is the sum of all products:
P = Ps + Pl + Pg
P = 36 + 27 + 45
P = 108
There are a total of 108 products.
