Mr. Lee left his fortune to his 3 sons, 4 daughters and his wife. Each son received twice as much as each daughter and his wife
ivolga24 [154]

Hey there! :)

Answer:

$3600.

Step-by-step explanation:

If the wife received $6000 which is a quarter of the money, solve for the total amount of the fortune:

1/4x = 6000

Multiply both sides by 4:

x = $24000

We can begin by subtracting the wife's amount from the total:

24000 - 6000 = $18000

He has 3 sons and 4 daughters. Let 'x' represent the amount the daughters received, and '2x' the amount the sons received.

18000 = 3(2x) + 4(x)

Distribute and combine the terms:

18000 = 6x + 4x

18000 = 10x

Divide both sides by 10:

18000/10 = 10x/10

x = $1800. This is the amount that each daughter receives. Since the sons receive '2x':

2(1800) = $3600.

Which of the following data sets represents a linear function?
Leokris [45]

Answer:

C

Step-by-step explanation:

to be a linear function the change in X and the change in Y has to be the same hence slope

A. x changes by+ 1 see 2,3,4,5, and y changes by +5, +7, +9 so A is not a linear function

B. X changes by -1 in all, y changes +1 for first 3 then -1 last, so B is not a linear function

C. X changes by +1 for all and y changes by -6 for all so is it is a linear function

D x changes by +1 for all and y changes by -1, +1, +3 so no linear fn.

NEED HELP ASAP I WILL MARK YOU BRAINLIST
kirza4 [7]

Answer:

The correct answer is: Option H: 14.4 units

Step-by-step explanation:

CD is a line segment and let M be the mid-point of the line segment.

As we know that a mid-point divides the line in two equal parts, this means that the length of line segment will be the double of distance between one end and mid-point

Given

C( 2,-1) => (x1,y1)

M(8,3) => (x2,y2)

The distance formula is given by:

d = \sqrt{(x_2-x_1)^2+(y_2-y_1)^2}

Putting the values

|CM|= \sqrt{(8-2)^2+(3-(-1))^2}\\|CM| = \sqrt{(8-2)^2+(3+1)^2}\\= \sqrt{(6)^2+(4)^2}\\=\sqrt{36+16}\\=\sqrt{52}\\= 7.211

We know that

CD = 2CM\\CD = 2 * 7.211\\CD = 14.422\\CD = 14.4

Hence,

The correct answer is: Option H: 14.4 units
