Which One Of These Four Triangles Is Not Similar? Explain How You Know. Write A Fewsentences And Be Sure

Answers

Answer 1

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.

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

48 ÷ 12 = 4
1 part of ratio = 4
4 x 7 = 28
so there are 28 boys.

Answer:

The number of boys is 20 and the number of girls is 28

Step-by-step explanation:

5+7= 12  that means 5/12 students are boys, while 7/12 students are girls

Boys: (5/12)48= 20

Girls: (7/12)48= 28

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

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
