1.) Distribute the -1/2 into (4y+20).
9y-2y-10

2.) Combine like terms.
7y-10

3.) Final solution!
7y-10

For the second problem, the answer(s) are solutions A & B.

Solution C cannot be correct because the it does not follow linear algebraic rules (PEMDAS). Solution D is also incorrect because the subtraction sign and division sign change, which does not follow any linear algebraic rules (PEMDAS).

Answers

Answer:

Step-by-step explanation:

Ratio of sides of  45-45-90 triangle =  x : x : x√2

x√2 is the side opposite to angle 90

So, from the picture,

x√2 = 2√2

x = [tex]\frac{2\sqrt{2}}{\sqrt{2}}[/tex]

x = 2

Ratio of sides of 30-60-90 tirangle = a : 2a : a√3

Short side that is oppoiste to 30° = a

Side opposite to 60° = a√3

Hypotenuse (oppoiste to 90°) = 2a

a = 2

y =a√3

  y = 2√3

Answer:

D, E

Step-by-step explanation:

In the table, r = 3p, and by converse, p = 1/3r. These options are D and E

Answer:

This is not college level stuff.

But the answer is D. r = 3p and E. p =r/3

Step-by-step explanation:

As you can see in the graph, all the r values are 3 times the p values, 9 = 3 x 3, 21 = 3 x 7, 24 = 3 x 8 and  so on. So, the equation is r = 3p. The same is also vice versa, r/3 = p.

what's the area of this figure?

Answers

Answer:

35

area of traingle b xh/2 5x4/2 - 10

area of square lxl - 5x5 -25

add- 35

Answer:

The answer would be 35.

Step-by-step explanation:

The area of the shape would be 35 square centimeters because if we divide the shape into 3 different shapes, a square on the bottom and 2 triangles at the top, we can multiply the square's length and width to get an area of 25. Next, we'll multiply the 2 triangles length of 4 with the width of 5 to get a total area of 20 from both of them, we'll then divide the area of 20 by 2 to get 10. Now add 20 and 10 to get 35.

Which action creates an equivalent system that will eliminate one variable when they are combined?

Answers

Answer:

(There's actually a few ways of solving this, but here's one)

Multiplying the second equation by 2.

EDIT: Because the question says it will eliminate a variable "when combined", implying adding the systems together. The actual correct answer is multiplying the second equation by -2.

(multiplying the second equation by -2 is the actual answer, my apologies)

Step-by-step explanation:

So it's clear that they are referring to the elimination method and not the substitution method for solving systems of equations.

In the elimination method, you subtract 2 equations in the hopes of the elimination of a variable.

If you multiply the second equation, 2x + 6y = 24, by 2, you get, 4x + 12y = 48.

This is helpful because when you subtract this from the first one, you eliminate x.

4x + y = 4

-(4x + 12y = 48)

is

-11y = -44

   b) 6.4% prefer pumpkin pie

   c) 80% did NOT prefer raspberry pie

   d) 235 people would be expected to say that their favorite pie is apple

       or blueberry.

14 a) 20% prefer Marlin

   b) 12% prefer Dolphins

   c) 48.33% prefer seahawks or sharks as their mascot.

   d) 116 students would be expected to say that their favorite mascot is a

       Penguin.

15 a) 20% prefer Science fiction

   b) 46 people would be expected to report mystery as their favorite

       genre.

   c) 810 people would be expected to report drama, history, or romance

       as their favorite genre.

Step-by-step explanation:

13.  *There are a total of 125 participants or customers.*

35 people prefer apple pie15 people prefer pumpkin pie.8 people prefer pecan pie.28 people prefer cherry pie.25 people prefer raspberry pie.14 people prefer blueberry pie.

a) 15/125 = 0.12 = 12%

   12% prefer pumpkin pie

b) 8/125 = 0.064 = 6.4%

   6.4% prefer pumpkin pie

c) Since 25 people preferred raspberry pie. 125-25= 100 people did NOT prefer raspberry pie.

    100/125 = 0.8 = 80%

    80% did NOT prefer raspberry pie

d) Out of 600 people, how many would you expect to say their favorite pie is apple or blueberry?

   Apple: 35/125 = 0.28 = 28%

   Blueberry: 14/125 = 0.112 = 11.2%

 

If there were 600 people:

    Apple: 600*0.28 = 168

    Blueberry: 600 * 0.112 = 67.2 (there can't be a 0.2 of a    

                                                        person, so it's rounded to 67)

168 + 67 = 235

235 people would be expected to say that their favorite pie is apple or blueberry.

14. *There are a total of 60 students.*

5 people prefer Penguins.12 people prefer Marlins.9 people prefer Seahawks.14 people prefer Dolphins.20 people prefer Sharks.

a) 12/60 = 0.2 = 20%

   20% prefer Marlin

b) 14/60 = 0.12 = 12%

   12% prefer Dolphins

c) Seahawks: 9/60 = 0.15 = 15%

  Sharks: 20/60 = 0.33 = 33.33%%

   15% + 33.33% = 48.33% prefer seahawks or sharks as their mascot.

d) If there are 1,400 students in the school, how many would you expect to choose the Penguins as their favorite mascots.

   Penguins: 5/60 = 0.083 = 8.33%

 

If there were 1,400 students:

    Penguins: 1,400*0.083 = 116.2 (there can't be a 0.2 of a    

                                                        person, so it's rounded to 116)

116 students would be expected to say that their favorite mascot is a Penguin.

15. *There are a total of 75 people.*

8 people prefer Action.4 people prefer Comedy.16 people prefer Drama.7 people prefer Mystery.10 people prefer Romance6 people prefer Science fiction3 people prefer Biography12 people prefer History9 people prefer Other

a) 6/75 = 0.2 = 20%

   20% prefer Science fiction

b) Out of 500 people, how many would you expect to report mystery as their favorite genre?

   Mystery: 7/75 = 0.093 = 9.3%

 

If there were 500 people:

    Mystery: 500*0.093 = 46.5 (there can't be a 0.5 of a    

                                                        person, so it's rounded to 46)

46 people would be expected to report mystery as their favorite genre.

c) If there are 1,600 people, how many would you expect to report drama, history, or romance as their favorite genre?

   Drama: 16/75 = 0.2133= 21.33%

   History: 12/75 = 0.16 = 16%

   Romance: 10/75 = 0.1333 = 13.33%

 

If there were 1,600 students:

    Penguins: 1,400*0.083 = 116.2 (there can't be a 0.2 percent of a    

                                                        person, so it's rounded to 116)

   Drama: 1,600*0.2133 = 341.28 (there can't be a 0.28 of a    

                                                        person, so it's rounded to 341)

   History: 1,600*0.16 = 256

   Romance: 1,600*0.1333 = 213.28(there can't be a 0.28 percent of a    

                                                        person, so it's rounded to 213)

341 + 256 + 213 = 810

810 people would be expected to report drama, history, or romance as their favorite genre.

which is a better value? 1 pound of apples for 2.15 or 3 pounds of apples for 5.76

Answers

Answer:

From what i've gotten on another answer on brainl It might be 3 pounds of apples for 5.76. On another question i've resarched i've also gotten $7.91.

Step-by-step explanation:

Sorry if none of these answers have helped you.

Answer:

The 2nd offer - 3 pounds of apples for 5.76

Step-by-step explanation:

1. Find the unit price for the 1st offer.

The unit price is 1 pound of apples for $2.15.  <-- given information

2. Find the unit price for the 2nd offer.

We can set up a proportion to find the unit price.

3 pounds / $5.76 = 1 pound / $x

Let x = how much 1 pound of apples are for the 2nd offer

Cross multiply

3 · x = 5.76 · 1

Simplify

3x = 5.76

Divide both sides by 3 to isolate x

x = 1.92 = $1.92 for a pound of apples (2nd offer)

3. Compare the two offers' unit prices.

$2.15   <-- 1st offer

$1.92   <-- 2nd offer

The second offer is the better value because it costs less for each pound of apple.

Create the equation of a circle that has a center at (1,3) and a radius of 4 units.

Answers

The equation of the circle centered at (1, 3) with a radius of 4 units is:

(x - 1)^2 + (y - 3)^2 = 16

How to write the equation of a circle?

For a circle with the center on the point (a, b) and radius R, the equation is:

(x- a)^2 + (y - b)^2 = R^2

In this case, the center is (1, 3) and the radius is R = 4, so the equation will be, so we just replace these in the general equation that we have above.

(x - 1)^2 + (y - 3)^2 = 4^2

  cost = 33

Step-by-step explanation:

Kruskal's Algorithm is a "greedy" algorithm that adds the next minimum-weight edge to the tree, provided that it does not create a loop.

__

The minimum-weight edge in the graph is DF, with weight 1.

The next minimum-weight edge is GH, with weight 2.

The next minimum-weight edge is AB, with weight 3.

The next minimum-weight edge is EF, with weight 4.

Edge DE is the next lowest-weight, but it creates a loop (DEF), so we ignore it.

BC is the next edge we'll add to our tree.

FG is the next edge we'll add to the tree.

Edge DG creates a loop, so we ignore it.

Edge FH creates a loop, so we ignore it.

CF is the next edge we'll add to the tree. This completes the minimum spanning tree using Kruskal's Algorithm.

Included edges are AB, BC, CF, DF, EF, GF, GH.

The cost of the tree is 3+6+10+1+4+7+2 = 33.

Find the measures of the interior angles?

Answers

Answer:

Angle C = 35

Step-by-step explanation:

Angles A and B are already given to you, so I will not be explaining how to find them. If you have any questions, let me know.

There are 2 ways to solve this problem; you can either use the sum of the interior angles or isosceles triangles.

Sum of Interior Angles

The interior angles of all triangles equal 180 degrees. We can use this information to create an equation.

First, set up the equation.[tex]110+35+x=180[/tex]Then, combine like terms.[tex]145+x=180[/tex]Next, subtract 145 from both sides[tex]x=35[/tex]

This means that angle C equals 35 degrees.

Isosceles Triangles

The image shows marks on 2 sides. These marks show that the sides are congruent. If a triangle has 2 congruent sides then it is isosceles. Isosceles always have 2 congruent angles as well. In addition, these congruent angles are always the angles opposite of the congruent sides.

In this case, the angles opposite of the congruent sides are angle A and angle C. Thus, angles A and C are congruent. If angle A is equal to 35, then angle C must also be 35.
