Triangle H J K is shown. Lines are drawn from each point to the opposite side and intersect at point G to form line segments H C, J E, and K D.
In the diagram, JG = 5 cm and GE = 10 cm. Based on this information, can G be a centroid of triangle HJK?

Point G cannot be a centroid because JG does not equal GE.
Point G cannot be a centroid because JG and GE are in the ratio 1:2.
Point G can be a centroid because GE and JG are in the ratio 2:1.
Point G can be a centroid because JG + GE = JE.

Answer:

0.89, 23/25, 93%

Step-by-step explanation:

1. Convert 23/25 to a decimal: 0.92; and then a percent: 92%

2. Convert 0.89 to a percent: 89%

3. Now, we can order these from least to greatest. In order they would obviously be 89, 92, and 93 percent.

Answer:

Step-by-step explanation:

El Angulo suplementario es cuando los ángulos sumados valen 180.

Ejemplo: Angulo suplementario de 15.

15+x=180

x=180-15

x=165

Entonces:

180=55+X

180-55=X

125=X

Step-by-step explanation:

Answer:

[tex]f^{-1}[/tex](x) = [tex]\frac{x-1}{2}[/tex]

Step-by-step explanation:

let y = f(x) and rearrange making x the subject, that is

y = 2x + 1 ( subtract 1 from both sides )

y - 1 = 2x ( divide both sides by 2 )

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

Change y back into terms of x with x = [tex]f^{-1}[/tex](x) , thus

[tex]f^{-1}[/tex](x) = [tex]\frac{x-1}{2}[/tex]

Answer:

$8

Step-by-step explanation:

5x / 5 = x

40 / 5 = 8

Marisa’s mother contribution was $8 each month.

An expression or mathematical expression is a finite combination of symbols that is well-formed according to rules that depend on the context.

Given that, Marisa’s savings account can be represented by the expression 5x+40. Marisa saved the same amount x each month for a period of 5 months. Her mother contributed an additional amount each month to Marisa’s savings account.

The amount in Marisa's account after 5 months = 5x + 40

She has saved $x each month for 5 months, therefore, her saving = 5x

Her mother given her an additional amount each month which is here shown by 40,

Since, if in 5 months it became 40, therefore, each month mother gave her = 40 / 5 = 8

Hence, Marisa’s mother contribution was $8 each month.

Answer:

  (-1, 0)

Step-by-step explanation:

We want the point (4x, f(4x)) to match (-4, 0). We already know that f(-4) = 0, so we want 4x = -4.

  4x = -4

  x = -1 . . . . divide by 4

The desired point is (-1, 0).

Step-by-step explanation:

Answer: There are 25 crates and 15 boxes in the truck when it is full.

Step-by-step explanation:

Let c= Number of crates , b= Number of boxes.

As per given,

[tex]c+b = 40[/tex]     (i)

[tex]3c=5b\\\\\Rightarow\ c=\dfrac{5b}{3}[/tex]        (ii)

Put value of c from (ii) in (i)

[tex]\dfrac{5b}{3}+b = 40\\\\\Rightarrow\ \dfrac{5b+3b}{3}=40\\\\\Rightarrow\ \dfrac{8b}{3}=40\\\\\Rightarrow\ 8b=3\times40\\\\\Rightarrow\ 8b=120\\\\\Rightarrow\ b=\dfrac{120}{8}=15[/tex]

put value of b in (ii),

[tex]c=\dfrac{5\times15}{3}=5\times5=25[/tex]

Hence, there are 25 crates and 15 boxes in the truck when it is full.

25 boxes 15 crates

We would get this solution by adding up the two sides comparing the ratios, hence: we get room for 3 crates for every 5 boxes that we can hold in the truck.

A ratio is an ordered pair of numbers a and b, written a:b where b does not equal 0. A proportion is an equation in which two ratios are set equal to each other. hence, if there is 3 crates and 5 boxes you could write the ratio as: 3 : 5 (for every 3 crates there are 5 boxes) 3 / 5 are boys and 5 / 3 are crates.

An ordinary deck of playing cards has 52 cards. There are four suits

-spades, hearts, diamonds, and clubs

-with 13 cards in each suit.

Spades and clubs are black; hearts and diamonds are red. One of these cards is selected at random. Let A denote the event that a red card is chosen.

Find the probability that a red card is chosen, and express your answer in probability notation.

Answer:

P(A) = 0.5

Step-by-step explanation:

We are told that the ordinary deck of playing cards has 52 cards.

Now, there are four suits

-spades, hearts, diamonds, and clubs

-with 13 cards in each suit.

Now, in a standard set of playing cards, there are 13 black spades and 13 black clubs as well as 13 red hearts and 13 red diamonds

Thus;

Number of red cards = 13 + 13

Thus;

Number of red cards = 26

Since, A denotes the event that red card is chosen.

This means that probability of choosing a red card is;

P(A) = number of red cards/total number in a deck of cards

P(A) = 26/52

P(A) = 0.5

Answer:

B. y=1/4x-2

Step-by-step explanation:

The -2 in this equation represents the y value. The graph passes through -2 on the y axis, so you automatically cancel out the rest of the answers.

Option B is correct, y=1/4x - 2 is the function which  best represented by the given graph.

The slope of the line is the ratio of the rise to the run, or rise divided by the run. It describes the steepness of line in the coordinate plane.

The slope intercept form of a line is y=mx+b, where m is slope and b is the y intercept.

The slope of line passing through two points (x₁, y₁) and (x₂, y₂) is

m=y₂-y₁/x₂-x₁

The line is passing through the points (0, -2) and (4, -1)

Let us find the slope m.

m = -1-(-2)/4

=1/4

So slope is 1/4

Now let us find the y intercept

-2=1/4(0)+b

-2=b

So equation will be y=1/4x-2

Hence, Option B is correct, y=1/4x - 2 is the function which  best represented by the given graph.
