All statements of congruent angles and congruent segments are correct.
A similarity statement can be written ...
Write a similarity statement ...
ABCD ~ HJKL
The reason written in the problem is incorrect. The polygons are similar, not congruent, so you cannot state that they are congruent as a reason for them to be similar.
This is the correct reason:
"The reason as why the two shapes are similar is that each angle A, B, C, D is congruent to each corresponding angle H, J, K, L, respectively, and the lengths of corresponding sides are proportional."
"A similarity ratio is a ratio that compares the lengths of the corresponding sides of two similar polygons. The ratio is written in the same order as the two
polygons."
For the similarity ratio, we use two corresponding sides.
AB = 8; HJ = 12
AB/HJ = 8/12 = 2/3
The similarity ratio of ABCD to HJKL is 2/3.

Step-by-step explanation: Angle 2 and 3 are vertical angles since they both share a vertex and has cross intersecting lines. Angle 6 and 7 are supplementary angles because they forma linear pair.
Answer:
I have multiple answers for this.
Verticle Angles: 2 &4, 3&1, 6&8, 7&5
Supplementary Angles: 2&1, 2&3, 3&4, 1&4, 6&7, 7&8, 6&5, 5&8
Step-by-step explanation:
Verticle angles are aross from one another, not next to each other, while the Supplementary angles ARE next to each other and not across from one another. I hope this helps you :)

Answers
Answer:
1/2 = 3/6
Step-by-step explanation:
Slope = Rise / Run
Rise = change in yaxis = y2 - y1
Run = change in x axis = x2 - x1
For the smaller triangle :
Rise = MO = 1 unit
Run = NO = 2 units
Thus;
slope = 1/2
For the larger triangle :
Rise = PR = 3 unit
Run = QR = 6 units
Thus ;
Slope = 3/6
Smaller = larger
1/2 = 3/6

first down, a football team lost 16 yd. After two
downs, the team had an overall gain of 5 yd. How
many yards were gained on second down?
Answers
Answer: +21
Step-by-step explanation:
Based on the information given, we are informed that at first down, a football team lost 16 yd and they after two downs, the team had an overall gain of 5 yd.
The number of yards that were gained on second down can be represented by x. We can then form the question as an equation as:
x - 16 = 5
x = 5 + 16
x = 21
The team gained 21 yards.

Let f(x) be defined on the positive real numbers as follows:
Start with a number x.

Square the result and add 2 more than the original number.
Finally, divide the result by 2 more than the square of the original number.
Required:
Write a formula for f(x).
Answers
Answer:
[tex]f(x)=\frac{(\sqrt{x}+x+3)^2+2+x}{x^2+2}[/tex]
Step-by-step explanation:
We have to find the formula for f(x)
Let x be the number
According to question
Now,
[tex]\sqrt{x}+x+3[/tex]
Now,
After squaring we get
[tex](\sqrt{x}+x+3})^2[/tex]
Add x+2 to above result then, we get
[tex](\sqrt{x}+x+3})^2+2+x[/tex]
Then,
[tex]\frac{(\sqrt{x}+x+3)^2+2+x}{x^2+2}[/tex]
Therefore, the formula for f(x) is given by
[tex]f(x)=\frac{(\sqrt{x}+x+3)^2+2+x}{x^2+2}[/tex]
A water mill grinds corn to make cornmeal. The water wheel has a radius of 18 feet. The wheel is rotating at 8 revolutions per minute. Find the linear speed, in feet per minute, of the water.
Answers
Answer:
904.9 feet per minute
Step-by-step explanation:
The Angular distance can be calculated using below expression
S= r θ ..............eqn(1)
Where
θ = angular distance travelled
r= Radius= radius of 18 feet
But angular distance can also be expressed as
θ = wt...................eqn(2)
w= angular speed= 8 rev per minute= (8 × 2π)
t= time
Velocity can also be expressed as
V= s/t............eqn(3)
Where
V= velocity
s= distance
t= time
Substitute eqn(2) into eqn(3)
V=( r θ)/ t................eqn(4)
Substitute eqn(2) into eqn(4)
V=( r w t)/ t
V= r w ..............eqn(5)
V= 18×(8 ×2π)
=288π
= 904.9 feet per minute
Hence, the linear speed, in feet per minute, of the water. is 904.9 feet per minute

A small pump can drain a pool in 9 hours. A large pump could drain the same pool in 3 hours. How long (to the nearest minute) will it take to drain the pool if both pumps are used simultaneously?
Answers
Answer: 22.5 hours
Step-by-step explanation:
Let t be the time taken by both of the pumps to drain the pool.
Given: Time taken by pump 1 to drain the pool alone= 9 hours.
Time taken by pump 2 to drain the pool alone= 3 hours.
If both pumps are used simultaneously, then
[tex]\dfrac1t=\dfrac19+\dfrac13\\\\\Rightarrow\ \dfrac1t=\dfrac{1+3}{9}\\\\\Rightarrow\ \dfrac1t=\dfrac49\\\\\Rightarrow\ t=\dfrac94\\\\\Rightarrow\ t=2.25[/tex]
Hence, it will take 22.5 hours to drain the pool if both pumps are used simultaneously.
