28) A TRIANGLE is a polygon, but not a quadrilateral
29) A RAY had an endpoint, but it’s not a line segment
Work out the angle marked x in each diagram you must show your working
Anwser: 41°
Okay so every triangle is 180° degrees in total.
We need to find the angle of x in the triangle BDC.
We know that the angle of x is 180 - ( x + 15)
We also have another triangle named BAD
Which angles are 90 + 56 + x
the angle of D in the triangle BDC is 180 -58 = 124
So 124 + 15 = 139
180 - 139 = 41
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).

I got it correct on founders edtell
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.

This diagram is a straightedge and compass construction. A is the center
of one circle,
and B is the center of the other. Explain how we know triangle ABC is
equilateral.
Answer/Step-by-step explanation:
Segments AB and AC are both radii of the circle with center A. All radii of a circle are always equal, tgerefire,:
[tex] AB = AC [/tex]
Segments AB and BC are both radii of the circle with center B. All radii of a circle are always equal, therefore:
[tex] AB = BC [/tex]
Thus,
[tex] AB = AC = BC [/tex]
∆ABC has sides AB, AC, and BC, which are all equal (equal radii).
Therefore, ∆ABC is an equilateral triangle.
An equilateral triangle has 3 equal sides.

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.

A pool contains 50 gallons of water and is filling at a rate of 2.3 gallons per minute. A second pool contains 102.2 gallons of water and is draining at a rate of 3.5 gallons per minute. After how many minutes will the pools contain the same amount of water?
At time t, the first pool contains 50+2.3t gal of water, while the second pool contains 102.2-3.5t gal.
They contain the same amount of water when these quantities are equal:
50 + 2.3t = 102.2 - 3.5t
5.8t = 52.2
t = 9
so the pools have the same amount of water after 9 min have passed.
The pools will contain same amount of water in 9 minutes
Let the number of minutes that the pools contain the same amount of water be represented by t.
Since the first pool contains 50 gallons of water and is filling at a rate of 2.3 gallons per minute, then this will be:
= 50 + (2.3 × t)
= 50 + 2.3t ......... equation i
The second pool contains 102.2 gallons of water and is draining at a rate of 3.5 gallons per minute. This will be:
= 102.2 - (3.5 × t)
= 102.2 - 3.5t ........ equation ii
Equate both equations and this will be:
50 + 2.3t = 102.2 - 3.5t
Collect like terms
2.3t + 3.5t = 102.2 - 50
5.8t = 52.2
Divide both side by 5.8
5.8t/5.8 = 52.2/5.8
t = 9
In conclusion, they'll have same amount of water in 9 minutes

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.

Kyle entered to run in a 5K (5 kilometers) race. He wants to figure out how many miles are in the race. 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

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

AB is parallel to CD, and EP is perpendicular to AB.
The number of 90° angles formed by the intersections of EP and the two parallel lines AB and CD is
Answer:
8 right angles
Step-by-step explanation:
1. If two lines are perpendicular then we know they form 4 right angles, so EP and AB from 4 right angles.
2. The question states that AB and CD are parallel. Since we know EP is intersecting AB and CD, we can say that EP is perpendicular to CD as well because of a theorem that states, "...that if there are two parallel lines in the same plane and there is a line perpendicular to one of them, then it is also perpendicular to the other one."
3. So because of that theroem, we can add another 4 right angles from the intersection of EP and CD.
4. When you add all the right angles together, you get 8 right angles in total.

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.

Which of the following correctly classifies the number -5 to all of the number sets in which it belongs?
=============================================
Explanation:
Any number you'll encounter so far in your math course will be a real number. This is until you get to something like [tex]\sqrt{-1}[/tex] which is a complex number, but your teacher may not have covered that chapter yet.
Anyways, -5 is a real number because we aren't taking the square root of a negative or anything like that.
-5 is also an integer, but that choice isn't listed. The set of integers is any positive or negative whole numbers, including 0 as well.
Furthermore, -5 is considered rational because -5 = -5/1. We can write -5 as a fraction of two integers where 0 is not in the denominator. With -5 being rational, it cannot be irrational. The term "irrational" means "not rational".

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
