Answer:

The actual distance between the cities is 1,200 Km

Step-by-step explanation:

Scaling

Objects can be represented in a reduced or augmented size by using scaling which is multiplying or dividing real dimensions by a constant factor. We use scaling when representing geographic locations on a map.

We are given the scale on a map as 1:20,000,000.

Two cities are 6 cm on the map. The actual distance is obtained by multiplying:

6 * 20,000,000 = 120,000,000 cm

Divide by 100 to convert to meters and by 1,000 to convert to km 120,000,000/100/1,000=1,200 Km

The actual distance between the cities is 1,200 Km

Hi, thank you for posting your question here at Brainly.

All you have to do to acquire the equation is to substitute the variables to the formula for A and simplify. Since A = 1/2*b*h and h = bsin(C), then A can be in terms of one variable only, which is b.

A = 1/2*b*bsin(c)
A = 1/2*b^2*sin(C)

Suppose that you measure a pen to be 10.5cm long. Convert this to meters.

Vinvika [58]

the answer: the following methods are the main rule according to the convertions we know this followin table: km hm dam m dm cm mm. if we want to change or convert any value, cm to meters, meters to km, or anything else, just follow this: converting dm (decimeter) to m, just multiply the number by 0.1, converting cm (centimeter) to m, just multiply the number by 0.01, converting mm (millimeter) to m, just multiply the number by 0.001, in our case, we have: convert 10.5cm to meters, so it is 10.5 x 0.01 =0.105 meters

A specialty muffin company makes muffins for $0.12 per muffin. The starting cost of the company is $300. How many muffins must t

V125BC [204]

Answer:

the company should make 2307 muffins before the Average cost reaches $0.25/muffin

Step-by-step explanation:

the total cost of making the muffins is

Total cost = fixed cost + variable cost = $300 + $0.12 / muffin *Q

where Q = number of muffins

the average cost is

Average cost = Total cost / number of muffins = ($300 + $0.12 *Q) / Q = $300/Q + $0.12 / muffin

then for Average cost= $0.25/muffin

$300/Q + $0.12 / muffin = $0.25/muffin

Q = $300 / ( $0.25/muffin- $0.12 / muffin ) = 2307.69 muffins ≈ 2307 muffins ( we are rounding down since we want to find the number before the cost goes below 0.25)

then the company should make 2307 muffins before the Average cost reaches $0.25/muffin
