The given ratios are not proportional.

What is a proportional relationship?

Proportional relationships are relationships between two variables where their ratios are equivalent. Another way to think about them is that, in a proportional relationship, one variable is always a constant value times the other. That constant is known as the "constant of proportionality".

The given fractions are 0.2/2.6 and 0.3/3.6

Here, 0.2/2.6 =2/26

= 1/13

Now, 0.3/3.6 =3/36

= 1/12

Therefore, the given ratios are not proportional.

Using what you know about angles and translations, find all of the angle
measures in the image below.

Answers

Answer:

∠1=135°

∠2=45°

∠3=45°

∠4=135°

∠5=135°

∠6=45°

∠7=45°

∠8=135°

Step-by-step explanation:

→∠1=∠4[Being vertically opposite angles]

→∠4=135°

→∠1=∠5[Corresponding angles]

→∠5=135°

→∠5=∠8[Being vertically opposite angles]

→∠8=135°

→∠1+∠2=180°[Sum of linear pair]

→∠2=180°-135°

→∠2=45°

→∠2=∠3[Being vertically opposite angles]

→∠3=45°

→∠3=∠6[Alternate angles]

→∠6=45°

→∠6=∠7[Being vertically opposite angles]

→∠7=45°

Answer:

∠1 = 135°

∠2 = 45°

∠3 = 45°

∠4 = 135°

∠5 = 135°

∠6 = 45°

∠7 = 45°

∠8 = 135°

Step-by-step explanation:

The diagram shows two lines that are intersected by a transversal.  (A transversal is a line that passes through two lines in the same plane at two distinct points).

When two lines are intersected by a transversal, the angles in matching corners are called Corresponding Angles
So  ∠1 = ∠5  , ∠2 = ∠6 , ∠3 = ∠7 , ∠4 = ∠8

Angles on one side of a straight line always add to 180°

Using the Angles on a Straight Line theorem

Angle 1 and 2 are on a straight line, so

∠2 = 180 - ∠1 = 180 - 135 = 45°

Similarly,

∠3 = 180 - ∠1  = 180 - 135 = 45°

∠4 = 180 - ∠3 = 180 - 45 = 135°

Using the Corresponding Angles theorem

As ∠1 = ∠5, then ∠5 = 135°

As ∠2 = ∠6, then ∠6 = 45°

As ∠3 = ∠7, then ∠7 = 45°

As ∠4 = ∠8, then ∠8 = 135°

What is the distance between (-1,5) and (2,9)

Answers

Answer:

5 units

Step-by-step explanation:

To find the distance between two points on a graph, we use the distance formula [tex]d=\sqrt{(y_2-y_1)^2+(x_2-x_1)^2[/tex] where [tex]d[/tex] is the distance between points [tex](x_1,y_1)[/tex] and [tex](x_2,y_2)[/tex].

For this problem, we will identify [tex](x_1,y_1)\rightarrow(-1,5)[/tex] and [tex](x_2,y_2)\rightarrow(2,9)[/tex]:

[tex]d=\sqrt{(y_2-y_1)^2+(x_2-x_1)^2}\\\\d=\sqrt{(9-5)^2+(2-(-1))^2}\\\\d=\sqrt{(4)^2+(3)^2}\\\\d=\sqrt{16+9}\\\\d=\sqrt{25}\\\\d=5[/tex]

Therefore, the distance between [tex](-1,5)[/tex] and [tex](2,9)[/tex] is 5 units

First, determine the value of x. Then find the measure of ∠BCA. Will brainlist first correct answer.
X=_________

Answers

Answer:

x = 16°    ||   ∠BCA = 57°

explanation:

All the angles lie on a straight line.

A triangles total interior angle is 180°

So we need to find the inner angle of each side and they are:

∠ABC = 180 - ( 5x + 12 )∠BCA = 180 - ( 10x - 37 )∠CAB = 180 - ( 9x + 1 )

So with this:

180 - ( 5x + 12 ) + 180 - ( 10x - 37 ) + 180 - ( 9x + 1 ) = 180

180 - 5x - 12 + 180 -10x +37 + 180 -9x-9 = 180

564 - 24x = 180

-24x = 180 - 564

-24x = -384

x = 16°

Then ∠BCA = 180 - ( 10x - 37 )

                   =  180 - ( 10 * 16 - 37)

                    = 57°

Answer:

[tex]x[/tex] = 24.57 to the nearest hundredth

Step-by-step explanation:

The three sides of a right-angled triangle have specific names:

The hypotenuse (H) is the longest side. It is opposite the right angle.The opposite side (O) is opposite the angle in question.The adjacent side (A) is next to the angle in question.

The 3 trigonometric ratios are:

[tex]sin(\theta)=\frac{O}{H} \\\\cos(\theta)=\frac{A}{H} \\\\tan(\theta)=\frac{O}{A}[/tex]

For the given triangle we are given the angle, the hypotenuse, and need to find the side that is ADJACENT to the angle.

Therefore, we would use the trig ratio:  [tex]cos(\theta)=\frac{A}{H}[/tex]

Substituting the values from the triangle:  [tex]cos(35)=\frac{x}{30}[/tex]

Multiply both sides by 30:  [tex]30cos(35)=x[/tex]

Therefore, [tex]x=24.57456133...[/tex]

So [tex]x[/tex] = 24.57 to the nearest hundredth

given points

(6,4) and (0,-5)

according to formula

One soulution contains 2 parts salt to 8 parts water, and another contains 3 parts salt to 5 parts water. How much of each should be mixed together in order to obtain 280 quarts of a soulution that is 3 parts salt to 7 parts water?

PLS HELP!!!!

Answers

Answer:

120

Step-by-step explanation:

Given,

Solution A contains 2 parts salt to 8 parts water

Solution B contains 3 parts salt to 5 parts water

Target Mixture contains3 parts salt to 7 parts water:

Expressing the salt concentration in decimal form

Solution A: 2/(2 + 8) = 2/10 = 0.20 salt

Solution B: 3/(3 + 5) = 3/8 = 0.375 salt

Mixed Solution: s/(3 + 7) = 3/10 = 0.30 salt

Since target mixture is 280 quarts

If the amount of 0.375 salt present in mixed solution = x

Then, the amount of 0.20 salt, y = 280 – x

Using a typical mixture equation

0.375x + 0.20(280-x) = 0.30(280)

0.375x + 56 - 0.20x = 84

Subtract 56 from both sides of the equation

0.375x - 0.20x + 56 – 56 = 84 – 56

0.375x - 0.20x = 28

0.175x = 28

Divide both sides of the equation by 0.175

0.175x/0.175 = 28/0.175

x = 160

y = 280 – x

y = 280 – 160

y = 120

A candy bar box is in the shape of a triangular prism. The volume of the box is 1,200 cubic centimeters.

Part A: What is the height of the box? Show your work. (5 points)


Part B: What is the approximate amount of cardboard used to make the sides of the candy box? Explain how you got your answer. (5 points)

Answers

Answer:

  A) 12 cm

  B) 520 cm² (just sides); 720 cm² (sides and base)

Step-by-step explanation:

A)

The volume of a triangular prism is given by the formula ...

  V = 1/2LWH . . . L = length, W = width, H = height

Filling in the given dimensions, we can find the height.

  1200 cm³ = 1/2(20 cm)(10 cm)H

  1200 cm³/(100 cm²) = H = 12 cm . . . . divide by the coefficient of H

The height of the box is 12 cm.

__

B)

Only the two rectangular faces with dimensions 13 cm by 20 cm are described in this problem statement as "sides." The area of each of those two faces is ...

  A = LW

  A = (20 cm)(13 cm) = 260 cm²

So, the area of the two sides is ...

  2 × 260 cm² = 520 cm² . . . . area of sides

__

If we also describe the base as a side of the box, its area is ...

  A = LW = (20 cm)(10 cm) = 200 cm²

Added to the area of the other two sides, the total "side" area is 720 cm².

Step-by-step explanation:

Let's say you have [tex]\frac{25}{4}[/tex].  Think about what the closest whole number 25/4 will give you.  Since 24 and 25 are close you can do 24/4 and get 6.  Now since you took one number away from the 25 you have a remainder.  Since the denominator is 4 your final answer would be 6[tex]\frac{1}{4}[/tex].

that of course, is only true if x + y, or our numerator doesn't turn into 0, if it does then our fraction becomes 0 and our equation goes south.  Keeping in mind that x,y and z are numeric values that correlate like so.

Answers

Answer: (5,5)

Step by step explanation:

We have the two equations

-7x + y = -30 and y = 2x - 5

one of the equations "define" y therefore we can plug the value of y into the other equation and solve for x

-7x + y = -30

plug in y = 2x - 5

-7x + 2x - 5 = -30

combine like terms

-5x - 5 = -30

add 5 to both sides

-5x = -25

divide both sides by -5

-5x/-5 = x and -25/-5 = 5

we're left with x = 5

we now plug in the value of x into one of the equations and solve for y

2x - 5 = y

x = 5

2(5) - 5 = y

multiply 2 and 5

10 - 5 = y

subtract

y = 5

the solution is (5,5)
