Which one of these four triangles is not similar? Explain how you know. Write a few
sentences and be sure to explain completely.
Answers
Answer:
Triangle D is different.
Every triangle is right-angled except for triangle D.
Proof for the 3rd angle of triangle D:
120+30+x = 180
150+x = 180
x = 30
Therefore, we can prove that there are no right angles in triangle D.

Answer:
Option B: If two lines are parallel, then alternate interior angles are
congruent.
Step-by-step explanation:
Notice that angles 3 and 6 are INTERNAL relative to the parallel lines, that is located in between the parallel lines. They are also alternate angles. Therefore, the correct answer is:
"If two lines are parallel, then alternate interior angles are congruent."

Answers
I don't know if you still need the answer, but it's in the picture
The correct statement is; B. When x increases by 1, y increases by 9. The function rule is y = 9x + 1
What is linear function?A linear function is represented as: y = mx + c
Where m is the slope and b is the intercept the value of y, when x = 0
From the given table, we have the following observations that;
As x increases by 1
The value of y increases by 9 and the slope of the table is 9
So, we have been given m = 9
Then y = 9x + c
Since an increment of 1 in the value of x will result in an increment of 9 in the value of y which means that; If x is reduced by 1, the corresponding value of y would reduce by 9.
When x = 1 then y = 10
This means that y = 9x + 1
The correct statement is; B. When x increases by 1, y increases by 9. The function rule is y = 9x + 1

Two angles of a triangle measure 55 and 20. What is the measure of the third angle of the triangle
Answers
Answer:
105
Step-by-step explanation:
180-(55+20)=105
105 is the missing angle because every triangle equals 180 degrees so you just subtract the angles you have already found from 180.
the person above me is correct i checked it so it is indeed 105!

4(y + 4) = 32
Answers
Answer:
y = 4
Step-by-step explanation:
4*y = 4y
4*4 = 16
4y+16=32
to get 4y alone, we subtract 16 from 32.
32-16 = 16
4y = 16
to get y alone, we divide 4 by 16
16/ 4 = 4
so, y = 4
Answer: y=4
Step-by-step explanation:
4(y+4)=32
Divide both sides by 4
y+4=8
Subtract 4 from both sides
y=4

A turkey cost $1.05 per pound. There are going to be fifteen people at Thanksgiving dinner. Plan for each person to eat two, 3/8-pound servings if turkey. How much will the turkey for Thanksgiving dinner cost?
Answers
Answer:
5.90625
Step-by-step explanation:
15*3/8=5 5/8
5 5/8=5.625
1.05*5.625=5.90625
The cost of the turkey for Thanksgiving dinner is $ 11.8125
What is an Equation?
Equations are mathematical statements with two algebraic expressions flanking the equals (=) sign on either side.
It demonstrates the equality of the relationship between the expressions printed on the left and right sides.
Coefficients, variables, operators, constants, terms, expressions, and the equal to sign are some of the components of an equation. The "=" sign and terms on both sides must always be present when writing an equation.
Given data ,
Let the cost of 1 pound of turkey = $ 1.05
Total number of people at the Thanksgiving dinner = 15 people
The number of servings for each person = 2 servings
The amount of turkey servings for each person = 2 x 3/8 pound servings
= 3/4 pound servings
Now , the equation will be
So , the total cost of 3/4 pound servings of turkey =
3/4 x cost of 1 pound of turkey
The total cost of 3/4 pound servings of turkey = 3/4 x 1.05
= $ 0.7875
Now , the cost for 15 people at the Thanksgiving dinner =
15 x total cost of 3/4 pound servings of turkey
The cost for 15 people at the Thanksgiving dinner = 15 x 0.7875
= $ 11.8125
Hence , The cost of the turkey for Thanksgiving dinner is $ 11.8125
