Answer:

80cm^3

Step-by-step explanation:

16/4 = 4

This means that the scale factor = 4

320cm^3 = Volume of BB

BB/4 = Volume of SB

320/4 = 80

Therefore, the volume of the small box = 80cm^3.

Ratling [72]

Answer:

The selling price is $79.53 .

Step-by-step explanation:

Formula

$Profit\ percentage = \frac{Profit\times 100}{Cost\ price}$

Let us assume that the cost price be x .

As given

Judy Garland Electronics operate on a net-profile rate of 20% on its printer cables.

If the markup is $8.95 and the overhead is $4.31 .

Selling price = Cost price + Markup price + Overhead price

Putting all the values in the above

= x + 8.95 + 4.31

= x + 13.26

Profit = Selling price - Cost price

= x + 13.26 - x

= 13.26

Putting all the values in the above

$20 = \frac{13.26\times 100}{x}$

$x = \frac{13.26\times 100}{20}$

$x = \frac{1326\times 100}{20\times 100}$

$x = \frac{1326}{20}$

x = $ 66.3

Thus

Selling price = x + 13.26

= 66.3 + 13.26

= $ 79.53

Therefore the selling price is $79.53 .

Hello.

The percent decrease in the mass of the pumpkin for this case will be given by:
(100 - (3.9 / 6.5) * 100) =
(100-60) =40%

After carving it, the pumpkin decreases a percent of 40% in the mass.

A population of mice is increasing exponentially. On Monday there were 120 most. One month later there were 132 most. Ready func

djyliett [7]

Answer:

$y=120 * 1.1^x$ --- function

The monthly rate is 10%

Step-by-step explanation:

Given

Let

$x \to months$

$y \to mice$

So, we have:

$(x_1,y_1) = (0,120)$ --- Monday

$(x_2,y_2) = (1,132)$ --- One month later

Required

The function

The function is represented as:

$y=ab^x$

In $(x_1,y_1) = (0,120)$ , we have:

$120 = a * b^0$

$120 = a * 1$

$120 = a$

$a=120$

In $(x_2,y_2) = (1,132)$ , we have:

$132 = a * b^1$

$132 = a * b$

Substitute: $a=120$

$132 = 120 * b$

Solve for b

$b = \frac{132}{120}$

$b = 1.1$

So, the function is:

$y=ab^x$

$y=120 * 1.1^x$

To calculate the monthly rate (r), we have:

$y =a(1 + r)^x$

Compare to: $y =ab^x$

$1 + r = b$

Make r the subject

$r = b-1$

Substitute $b = 1.1$

$r = 1.1-1$

$r = 0.1$

Express as percentage

$r = 0.1*100\%$

$r = 10\%$
