Answer:

124 in

Step-by-step explanation:

Perimeter Rectangle = 2(length + width)

856 = 2(304 + width)

856 = 608 + 2width

248 = 2width

124 = width

<h2>Check</h2>

856 = 2(304+124)

856 = 2(428)

856 = 856

Correct

16 factory workers made 40 pieces in a certain amount of time.

qwelly [4]

a) The quantities vary directly

b) The constant of variation is 2.5

Step-by-step explanation:

Lets us revise the direct and inverse variation

If y varies x directly, then y = kx, that means the ratio between them is constant ( $\frac{y}{x}=k$ ) , they increased together and decreased together, k is the constant of variation
If y varies x inversely, then yx = k, that means when x increased y must be decrease ( $y=\frac{k}{x}$ ) k is the constant of variation

∵ 16 factory workers made 40 pieces in a certain amount of time

- If the number of worker increased, then the number of pieces

increased in the same certain time, if the number of worker

decreased, then the number of pieces also decrease in the

same certain time

∴ The the number of workers and the number of pieces produce

vary directly

∴ Number of pieces produced = k × number of worker

a) The quantities vary directly

∵ The number of worker = 16

∵ The number of pieces produced = 40

- Substitute these values in the equation of variation above

∴ 40 = k × 16

- Divide both sides by 16

∴ k = 2.5

b) The constant of variation is 2.5

(10 points/I really need help) Tomas needs exactly 6 potatoes to make 12 potato pancakes?? Which of the following statements are

kirill115 [55]

The answers are A, B, and D.

The given information is that Tomas needs 6 potatoes to make 12 potato pancakes. Thus, we can assume it takes 1 potato to make 2 potato pancakes.

An answer choice must have two times more pancakes than potatoes. Only A, B, and D satisfy this. The others can be confusing if the multiplication is not executed properly.

A bag has six balls labeled a,b,c,d.e and f . One ball will be randomly picked, and its letter will be recorded as the outcome.

Dvinal [7]

<h3>Sample space = {a,b,c,d,e,f}</h3><h3>Event space = {a,c}</h3>

We simply list all of the letters mentioned as they are the possible outcomes. We can only pick one item from the sample space. The event space is the set of outcomes where we want to happen (picking either an 'a' or 'c').

What are the coordinates of the point on the directed line segment from (–9, -7) to

pentagon [3]

Answer:

Step-by-step explanation:

Saving the long, drawn out derivation of the formulas to find the x and y coordinates of the directed point, suffice it to say that it is:

x coordinate: $\frac{bx_1+ax_2}{a+b}$ and

y coordinate: $\frac{by_1+ay_2}{a+b}$

where x1, x2, y1, and y2 are the coordinates from the given points and a and b are the numbers in the ratio, namely a = 3 and b = 4. Filling in accordingly:

the x coordinate of the directed point is

$\frac{4(-9)+3(-2)}{7}$ which simplifies down to -6, and

the y coordinate of the directed point is

$\frac{4(-7)+3(7)}{7}$ which simplifies down to -1.

The coordinate of the point is (-6, -1). Write that down so you don't forget it.

If you purchase a dozen bagels, you save 10% If a dozen bagels originally costs $11.50, what is the sale price

KonstantinChe [14]

10 percent of 11.50 is 1.15. Subtract that from 11.50 and you would get 10.35. The sale price would be $10.35
