Answers

Answer 1
Answer:

Answer:

  • B. 12

Step-by-step explanation:

Since Z is midpoint of SR and Y is midpoint of QR, so as per triangle midpoint theorem ZY is parallel to SQ and measures half of its value:

  • SQ = 2ZY
  • 3x - 8 = 2(x + 2)
  • 3x - 8 = 2x + 4
  • 3x - 2x = 4 + 8
  • x = 12

Correct answer choice is B
Answer 2
Answer:

Answer:

the answer is B.12 ......

Kylie explained that (–4x + 9)2 will result in a difference of squares because (–4x + 9)2 = (–4x)2 + (9)2 = 16x2 + 81. Which statement best describes Kylie’s explanation?Kylie is correct.
Kylie correctly understood that it is a difference of squares, but she did not determine the product correctly.
Kylie did not understand that this is a perfect square trinomial, and she did not determine the product correctly.
Kylie determined the product correctly, but she did not understand that this is a perfect square trinomial.

Answers


The expression (-4x + 9)^2 cannot be equal to (-4x)^2 + 9^2 because it is actually equal to the product of two factors (3 + 2sqrt x) (3- 2 sqrt x). One cannot use obviously distributive property. Hence the answer to this problem should be C. as she did not understand both perfect square trinomial and did not determine the product 
The correct answer is: (C) Kylie did not understand that this is a perfect square trinomial, and she did not determine the product correctly.

Explanation:
Kylie did not determine the product correctly, as the perfect-square trinomials are of the form:
a^2x^2 \pm 2axb \pm b^2

and are expressed in the squared-binomial form as:
(ax \pm b)^2

The correct product would be:
(-4x + 9)^2 = (-4x)^2 + 2(-4)(9)x + (9)^2 = 16x^2 - 72x + 81

Hence the correct answer is that Kylie did not understand that this is a perfect square trinomial, and she did not determine the product correctly (Option C).

What do 20-(12+6) equal

Answers

Answer:

2

Step-by-step explanation:

Since the 12 + 6 are parenthesis, we do these first

12 + 6 = 18

Then will solve the rest, 20 - 18

20 - 18 = 2, therefore leaving us with the answer of 2

The vertices of the feasible region of the inequality is given by 2x + 3y > 12 and 5x + 2y ≥ 15

What is an Inequality Equation?

Inequalities are the mathematical expressions in which both sides are not equal. In inequality, unlike in equations, we compare two values. The equal sign in between is replaced by less than (or less than or equal to), greater than (or greater than or equal to), or not equal to sign.

In an inequality, the two expressions are not necessarily equal which is indicated by the symbols: >, <, ≤ or ≥.

Given data ,

Let the inequality equation be represented as A

Now , the value of A is

Substituting the values in the equation , we get

2x + 3y > 12   be equation (1)

5x + 2y ≥ 15   be equation (2)

where x , y ≥ 0

Now , the inequalities are plotted on the graph ,

where the vertices of the feasible region is given by A , B and C

A ( 0 , 4 ) , B ( 21/11 , 30/11 ) , C ( 3 , 0 )

Hence , the inequalities are solved and the graph is plotted

Milk and cream are mixed together for a recipe. The total volume of the mixture is 1 cup. If the milk contains 2% fat, the cream contains 18% fat, and the mixture contains 6% fat, how much cream is in the mixture?A. 1/5 cup
B. 1/4 cup
C. 3/4 cup
D. 4/5 cup

Answers

Thank you for posting your question here at brainly. The cream will be 1/4 cup if the  milk contains 2% fat, the cream contains 18% fat, and the mixture contains 6% fat. I think its 1/4 because about 25% is fat and 25 x 4 = 100 assuming that the "100" is the cup. So 25% is 1/4 of the cup.

Answer:

Option B

Step-by-step explanation:

Given that milk and cream are mixed together for a recipe. The total volume of the mixture is 1 cup.

Let x cups of milk be mixed with 1 cup of cream

Total fat in the mixture = 0.02x+0.18

=6% of x+1 = 0.06(x+1)

i.e. 0.02x+0.18 =0.06x+0.06

0.04x = 0.12

x =3

So 3 cups of milk and 1 cup of cream would be mixed

Or B) 1/4 cup cream would be mixed
