A baker, in 70 minutes, iced 40 cupcakes and, in 49 minutes, iced 28 cupcakes. What is the constant of proportionality?

Zinaida [17]

Answer:

$\frac{4}{7}$

Step-by-step explanation:

The constant of proportionality is the slope of the line joining the two points

(70,40) and (49,28).

Recall the slope formula:

$m = \frac{ y_2 - y_1 }{ x_2 - x_1}$

We substitute the point to get:

$m = \frac{28 - 40}{49 - 70} = \frac{ - 12}{ - 21} = \frac{4}{7}$

<u>Alternatively</u>:

A proportional relation is given by

$y = kx$

where k is the constant of proportionality.

Using any point, we substitute and solve for k.

$40 = 70k$

$k = \frac{40}{70} = \frac{4}{7}$

RoseWind [281]

Answer:

Labels did she print is 36.

Step-by-step explanation:

Given : Ms kaimal prints out address labels on 3 sheets of paper each sheet is entirely covered in labels each label takes up $\frac{1}{12}$ of a sheet.

To find : How many labels did she print ?

Solution :

$\frac{1}{12}$ of a sheet takes up 1 label.

So, 1 of a sheet takes up $\frac{1}{\frac{1}{12}}$ label.

1 of a sheet takes up 12 label.

Then, 3 of a sheet takes up $12\times 3$ label.

3 of a sheet takes up 36 label.

Therefore, Labels did she print is 36.

4) During a school carnival, students from the middle school raised money by selling crafts, food, game tickets, and school play

ioda

$225 was earned from the craft sales

and $40 was earned from the play.

Given, During a school carnival, students from the middle school raised money by selling crafts, food, game tickets, and school play admissions.

Of each dollar earned, $0.15 came from games. Craft sales earned 3 times as much as games. Food sales were 4 times the amount earned from the play.

Let the amount earned by play be x,

Now, Games earned = 0.15×500 = $75

Also, crafts earned 3×75 = $225

Now, as play earned x, then food earned 4x.

According to question,

x + 75 + 225 + 4x = 500

5x + 300 = 500

5x = 200

x = 40

So, the amount earned by Play be, $40

and the amount earned by Food be $160.

Hence, $225 was earned from the craft sales

and $40 was earned from the play.
