14 Metric System Conversion. Convert 26.2 miles into kilometers and round to the nearest tenth. (Hint: 1 mile= 1.609 km)
Mekhanik [1.2K]

Answer:

42.1558 km

Step-by-step explanation:

We know that 1 mile = 1,609 km

Then use this data as a conversion factor.

If we want to transform miles to kilometers then our conversion factor should be:

\frac{1,609\ km}{1\ miles}

Now we must multiply the number of miles by this factori and thus we obtain the equivalent in kilometers

26.2*\frac{1,609\ km}{1\ miles} = 42.1558 km

Reil [10]

Answer:

a)The company has to 250 cameras in one day to equal its daily cost

b)Their daily profit  will be $400

Step-by-step explanation:

Given:

overhead expenses = $1500

labour and materials expenses = $9

cameras sell for $15 each

To Find:

(a)How many cameras must the company sell in one day to equal its daily cost

(b) If the manufacturer can increase production by 50 cameras per day, what would their daily profit be?

Solution:

a) let the number of cameras sold per day be x

Total daily cost = overhead expenses +labour and materials expenses

Total daily cost = 1500 + 9x--------------------------(1)

Total daily revenue = 15x------------------------------(2)

Equating (1) and (2)

1500 + 9x = 15x

1500 = 15x- 9x

1500 = 6x

x= \frac{1500}{6}

x= 250

So, the company has to 250 cameras in one day to equal its daily cost.

b) increasing production by 50 cameras per day will give a daily profit of

=>50 X (17-9)

=>50 X 8

=> 400
