Answer:
I believe the answer is J. the corresponding angles are proportional, and the corresponding sides are congruent
Step-by-step explanation:
hope this helps :)
If the triangles below are similar the corresponding angles are proportional, and the corresponding sides are congruent. Option J is correct,
What is the similarity law for triangles?It 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.
Congruent triangles are those that are exactly the same size and shape. Congruent is represented by the symbol ≅ When the three sides and three angles of one triangle match the dimensions of the three sides and three angles of another triangle, they are said to be congruent.
Thus, if the triangles below are similar the corresponding angles are proportional, and the corresponding sides are congruent. Option J is correct.

using the slope formula find the slope of the line through the points (0,0) and (3,9) use pencil and paper explain how you can use mental math to find the slope of the line
Answer:
The answer is 3
Step-by-step explanation:
The slope is the intensity of inclination thus the slope of the line that passes through points (0,0) and (3,9) is 3.
What is the slope?A slope is a tangent or angle at a point and a slope is the intensity of inclination of any geometrical lines.
Slope = Tanx where x will be the angle from the positive x-axis at that point.
The slope of a line that passes through (x₁, y₁) and (x₂, y₂) is,
Slope = (y₂ - y₁)/(x₂ - x₁)
Since the given line is passing through (0,0) and (3,9).
Slope = (9 -0)/(3 - 0)
Slope = 3
Since the line is passing through the origin (0,0) so we can do it by mental math to divide y and x coordinate directly like 9/3 = 3.
Hence "The slope is the intensity of inclination thus the slope of the line that passes through points (0,0) and (3,9) is 3".

how do you solve for Y
problem #5
9514 1404 393
Answer:
y = 26
Step-by-step explanation:
You have already correctly solved for x, so you know that ...
m∠8 = 4(17)+10 = 78
Angle 12 is an alternate interior angle with respect to angle 8, so is congruent to angle 8.
m∠12 = m∠8
3y = 78
y = 78/3 . . . . divide by the coefficient of y
y = 26
Identify the scale factor
Answer:
Step-by-step explanation:
k = 4/24 = 1/6
Answer:
The scale factor is 1/6.
Step-by-step explanation:
the larger triangle is 6 times larger than the small triangle because 24 divided by 4 is 6, so therefore the scale factor of the big triangle to the small triangle is 1/6.
how to find the slope from a table of data
The slope of a linear line (or a linear equation) can be found by simply taking 2 values for x and y and then using the slope formula which is [tex]\frac{dy}{dx}[/tex] or:
[tex]\frac{y_{2} - y_{1}}{x_{2} - x_{1}}[/tex]
Example:
Let's say you're give this table:
x: 1, 2
y: 1, 2
Following the steps which I gave, you take 1 value for the y (preferably the larger one) which in this cause will be 2 and then another y from the table which would be 1
Do the same for x
Now plug the values taken in the slope formula and you get:
[tex]\frac{2 - 1}{2 - 1}[/tex]
[tex]\frac{1}{1} = 1[/tex]
Therefore the slope is 1.
Answer:
Rise/run
Rise over run.
Step-by-step explanation:
To find the slope pick two perfect spots on the line when the coordinates are not decimals.
Then, take those two points and figure out the distance. You will use rise/run.
so rise is how much you either go up or down and run is how much you either go right or left. so how much you'll go up or down? how much will you move right or left?
Lets say you have to go up 5 and then left 7 to get to the coordinate.
That's your slope! you went up so it's positive and you went left so it's negative. Rise over run : rise 5 left 7 so, 5 and -7 which is 5/-7 and that's your slope!

Carlos picked one of four equations in the table to solve. Carlos correctly solved the equation he chose. His answer was x = 5.
Equation 1 6x + 40 = 82
Equation 2 12x- 1 = 2
Equation 3 2x + 21 = 31
Equation 4 18x+ 9 = 13
Which equation did Carlos choose to solve?
the slope is 5 passing through ( -1, 4)
Answer:
y = 5x + 9
Step-by-step explanation:
Assuming you require the equation of the line.
The equation of a line in slope- intercept form is
y = mx + c ( m is the slope and c the y- intercept )
Here m = 5, thus
y = 5x + c ← is the partial equation
To find c substitute (- 1, 4) into the partial equation
4 = - 5 + c ⇒ c = 4 + 5 = 9
y = 5x + 9 ← equation of line

1) Roger has four dollars more than double the amount that Roderick has in his wallet. Together, they have a total of $224. How much money does Roger have?
Answer:
$150.66
Step-by-step explanation:
Let that amount of money Roger has = x
The amount of money Roderick has = y
Roger has four dollars more than double the amount that Roderick has in his wallet.
x = 2y + 4
Together, they have a total of $224.
x + y = $224....... Equation 1
We substitute 2y + 4 for x in Equation 1
2y + 4 + y = $224
3y + 4= $224
3y = $224 - 4
3y = $220
y = $220/3
y = $73.333333333
y = $73.33
How much money does Roger have?
x = 2y + 4
x = 2(73.33) + 4
x = $146.66 + 4
x = $150.66
Roger has $150.66

What is addition?Addition is a way of combining things and counting them together as one large group. ... Addition in math is a process of combining two or more numbers.
here, we have,
Let's remember that the complete revolution of the wheel is 360 degrees, and the distance traveled by a complete revolution is the length of the circumference: 2*pi*radius.
The inicial height of the point is 6 ft, and the radius of the wheel is 1 ft.
When the distance traveled is 0, the wheel turned 0 degrees, and the point will be in its inicial position (the lower position of the wheel), which is 6 feet high.
So the height will be a = 6 + 0 = 6 ft
When the distance traveled is pi/2, the wheel turned 90 degrees, and the point will be half the complete height of the wheel, which is 2 feet.
So the height will be b = 6 + 1 = 7 ft
When the distance traveled is pi, the wheel turned 180 degrees, and the point will be at the top of the wheel, which is 2 feet higher than the lower point of the wheel.
So the height will be c = 6 + 2= 8 ft
When the distance traveled is 3pi/2, the wheel turned 270 degrees, and the point will be half the complete height of the wheel, which is 2 feet.
So the height will be d = 6 + 1 = 7 ft
When the distance traveled is 2pi, the wheel turned 360 degrees, and the point will be in its inicial position (the lower position of the wheel), which is 6 feet high.
So the height will be e = 6 + 0 = 6 ft
So the answers are:
a = 6, b = 7, c = 8, d = 7 and e = 6

How many integers between 2020 and 2400 have four distinct digits arranged in increasing
order? (For example 2957 is one such integer)
(B) 10
(C) 15
(D) 21
e 28
Answer:
the answer is E
Step-by-step explanation:
We want to find how many integers are between 2020 and 2400 such that a criteria is meet, and the criteria is that the four digits are different and are arranged in increasing order.
We will see that there are 15 of these numbers between 2020 and 2400, so the correct option is C.
---------------------------
To count the number of digits that meet the given criteria, we first need to analyze how the criteria is.
If the numbers must be in increasing order, then the smallest number that can be in the hundreds place is 3 (the smaller integer larger than 2).
so we have:
23__
The number next to the 3 can be a 4, for example:
234_
And the final number can be any number larger than 4, so we have {5, 6, 7, 8, 9} a total of 5 options.
If instead of a 4, the number next to the 3 is a 5, we have:
235_
And the number next to the five can be any digit larger than 5, so now we have 4 options.
If instead of a 5, we have a 6, we will have 3 options to put after the 6.if instead of a 6, we have a 7, we will have 2 optionsif instead of a 7, we have an 8, we will have 1 option.Now, we can't have another number than a 3 in the hundreds place, because if we put a 4 there, we are out of the range, and 3 is the smallest digit that we can use there.
Then we already saw all the possible numbers that we can make, adding the numbers of options that we got above we will get:
5 + 4 + 3 + 2 + 1 = 15
This means that are 15 of these numbers between 2020 and 2400. Then the correct option is C.
