Answer:

Step-by-step explanation:

the first nuclear every time in this topic is y and the second one is x

Answer:

x = 2/3

Step-by-step explanation:

Add the numbers

[tex]\frac{1}{3}+3=4-x[/tex]

[tex]\frac{10}{3}=4-x[/tex]

Rearrange terms

[tex]\frac{10}{3}=-x+4[/tex]

Subtract 4 from both sides of the equation

[tex]\frac{10}{3}-4=-x+4-4[/tex]

Simplify

[tex]\frac{-2}{3}=-x[/tex]

Divide both sides of the equation by the same term

[tex]\frac{-2}{3}/1=\frac{-x}{1}[/tex]

Simplify

[tex]x=\frac{2}{3}[/tex]

Answer:

x=10

y = -9

Step-by-step explanation:

-8x - 10y = 10

3x + 2y = 12

Multiply the second equation by 5

5(3x + 2y) = 12*5

15x+10y = 60

Add this to the first equation to eliminate y

-8x - 10y = 10

15x+10y = 60

-----------------------

7x  + 0y  = 70

Divide by 7

7x/7 = 70/7

x = 10

Now find y

3x+2y = 12

3(10) +2y = 12

30 +2y =12

Subtract 30 from each side

2y = 12-30

2y = -18

Divide by 2

2y/2=-18/2

y = -9

The amount of material needed by Marta to make the flag is;

[tex]\rm Area =\sqrt{50(50-d_1)(50-d_2)(50-d_3)}[/tex] square inch.

The total cost of making the flag is;

[tex]\rm 0.15 \times\rm \sqrt{50(50-d_1)(50-d_2)(50-d_3)}[/tex] dollar.

Given

Marta is making a flag with the given dimensions.

The perimeter of the flag is 100 inches.

Let us consider that the flag has a triangular shape.

According to the Hero's formula;

The area of the triangle is given by;

[tex]\rm Area =\sqrt{s(s-a)(s-b)(s-c)}[/tex]

Where, s is the semi perimeter and a, b, and c are the sides of the triangle.

Semi perimeter s = P/2,

Since the perimeter of the flag is 100 inches.

[tex]\rm S=\dfrac{100}{2}\\\\S=50[/tex]

The dimensions of triangular shape are [tex]\rm d_1, d_2 \ and \ d_3[/tex].

Then,

The area of the triangular flag becomes;

[tex]\rm Area =\sqrt{s(s-a)(s-b)(s-c)}\\\\\rm Area =\sqrt{50(50-d_1)(50-d_2)(50-d_3)}[/tex]

So the amount of material needed to make the flag is;

[tex]\rm Area =\sqrt{50(50-d_1)(50-d_2)(50-d_3)}[/tex]

Therefore,

The cost of material = C = $0.15 per square inch

So the total cost in making the flag will be;

[tex]\rm C\times A=0.15 \times A\\\\=0.15 \times\rm \sqrt{50(50-d_1)(50-d_2)(50-d_3)}[/tex].

Hence, The amount of material needed by Marta to make the flag is [tex]\rm Area =\sqrt{50(50-d_1)(50-d_2)(50-d_3)}[/tex].

Answer:

1/4

or 25%

or 0.25

Step-by-step explanation:

With a question like this, you have to multiply.

1/2 * 1/2 = 1/4

or

0.5 * 0.5 = 0.25

Answer: 9/16

Work Shown:

14 red + 10 yellow + 5 green + 3 purple = 32 total

(32 total) - (14 red) = 18 that aren't red

18/32 = 9/16 is the probability of picking something that isn't red.

The statements that are true regarding the diagram given are:

The triangle sum theorem states that all the three interior angles in a triangle have a sum of 180 degrees all together.

Thus, in the diagram given, the statements that are all true are:

m∠3 + m∠4 = 180° (angles on a straight line)

m∠4 = m∠1 + m∠2 (external angle theorem)

m∠1 + m∠2 + m∠3 = 180° (triangle sum theorem).

Step-by-step explanation:

I got it right.

Answer:

{(0, 0), (1, 2), (2, 4), (3, 4)}

Step-by-step explanation:

A set of ordered pairs that represent a function is one in which each different ordered pair has a unique x-coordinate (so no two different ordered pairs can have the same x -coordinate).

Therefore, {(0, 0), (1, 2), (2, 4), (3, 4)} is a function as each different ordered pair has a unique x-coordinate.

The other sets all have different ordered pairs that share the same x-coordinate and so these sets do not represent functions.

The vertical line test is also used to determine whether a graph represents a function. If the vertical line intersects the graph only once, then the curve represents a function.  This test can be applied to ordered pairs, in that if two ordered pairs have the same x-coordinate but different y-coordinates, they will be on the same vertical line and therefore do not represent a function.

Answer:

Step-by-step explanation:

  f(g(2)) = f(0) = 0

  g(f(2)) = g(2) = 0

  f(f(2)) = f(2) = 2

  g(g(2)) = g(0) = 4

  (f+g)(4) = f(4) +g(4) = 4 +4 = 8

  (f/g)(2) = f(2)/g(2) = 2/0   ⇒   DNE

_____

To find the value of the function on the graph, locate the x-value on the horizontal axis and work up the vertical line to the curve of interest. Read the value of that point from the vertical scale.

Answer:

134 bottles

Step-by-step explanation:

For this, I set up a proportion :

60.30/x = 0.45/1

60.30(1) = 0.45x

60.30/0.45 = 0.45x/0.45

x = 134 :)

Answer:

134 bottles

Step-by-step explanation:

conversion of dollars to cent:

$1 equals to 100 cents.

$60.30 will be (60.30*100) cents → 6030 cents

Bottles sold: total money / each bottle cost.
                  →   6030  /  45
                  →   134

So 134 bottles are sold for 45 cents to earn $60.30 or 6030 cents.

Answer:

113

Step-by-step explanation:

290 - 64 = 226

226 ÷ 2 = 113

Answer:

Given, x,y and 40 are the angles of a triangle.

Therefore, x+y+40=180

x+y=140

The difference between the two angles x and y is 30.

Therefore, x−y=30 ....(2)

Add equations (1) and (2), we get

2x=170

⇒x=85

Substitute this value n equation (2), we get

85−y=30

⇒y=85-30

⇒y=55

Therefore, angles of a triangle are x=85, y=55 and 40.

Answer:

Step-by-step explanation:

for x :

180° - 40° = 140°  

40° / 2 = 20°

x = 20°

for y :

20° + 90° = 110°

180° - 110° = 70°

x = 70°
