Find the distance between 13/3 and the square root of 16/9

Ainat [17]

Answer:

Root 16=4

Root 9=3

Therefore it becomes 4/3

Now distance between the two= 13/3-4/3 which is equal to 9/3 and 9 divided by 3 is 3.

Therefore the distance between the two on a number line is 3

5(y+1)=30 solve for y

Mkey [24]

Answer:y=5

Step-by-step explanation:

5(y+1)=30

Divide both sides by 5

5(y+1)/5=30/5

We get y+1=6

Subtract 1 from both sides

y+1-1=6-1

We get y=5

PLEASE HELP!!! 100 points (make sure to show work and be correct)

tresset_1 [31]

Answer:

1. B and E

2. B

Step-by-step explanation:

1. Looking at the line, let's try to establish a relationship between x and y. Take one point (12, 80) and divide y by x:

80 / 12 = 20 / 3

Similarly, if we take (3, 20), we get the same relationship:

20 / 3 = 20 / 3

That means we need to select an ordered pair that follows this relationship:

A. (14, 100) ⇒ 100 / 14 = 50 / 7 --- wrong

B. (15, 100) ⇒ 100 / 15 = 20 / 3 --- correct

C. (16, 100) ⇒ 100 / 16 = 25 / 4 --- wrong

D. (16, 120) ⇒ 120 / 16 = 15 / 2 --- wrong

E. (18, 120) ⇒ 120 / 18 = 20 / 3 --- correct

The possible answers are B and E.

2. Let's say Maya sells b bracelets. That means that she makes 3 * b = 3b dollars for these b bracelets. Look at the answer choices to see which one will have 3 in the x-coordinate and a multiple of 3 in the y-coordinate:

A. (3, 5) ⇒ 5 isn't a multiple of 3, so wrong.

B. (3, 9) ⇒ 3 is the x-coordinate and 9 = 3 * 3, so this is correct.

C. (3, 7) ⇒ 7 isn't a multiple of 3, so wrong.

D. (2, 3) ⇒ 3 isn't even the x-coordinate, so wrong.

The correct answer is thus B.

Manny wants to proportionally enlarge a rectangular window that has a length of 36 inches and a width of 24.5 inches.

stira [4]

The new width of the window should be 36.75 inches ⇒ 2nd answer

Step-by-step explanation:

The proportionally is two quantities having a constant ratio

The quantities y and x are proportional if:

$\frac{y}{x}$ = k, where k is the constant of proportionality
y = k x
$\frac{y_{1}}{x_{1}}=\frac{y_{2}}{x_{2}}$

∵ Manny wants to proportionally enlarge a rectangular window

- That means the new dimensions are proportion with the

original dimensions

∴ New dimensions = k × original dimensions

- k is the constant of proportionally

∵ The original length = 36 inches

∵ The new length = 54 inches

- Substitute then in the equation above to find k

∵ 54 = k × 36

- divide both sides by 36

∴ 1.5 = k

∴ The new dimensions = 1.5 × original dimensions

∵ the original width = 24.5 inches

∴ The new width = 1.5 × 24.5 = 36.75 inches

The new width of the window should be 36.75 inches
