Answer:

30 miles

Step-by-step explanation:

So since we know the scale of the map (3 in : 15 mi) we will just have to find out how much 3 inches fits into 6 inches and then multiply the result by 15 miles. So we do the following steps.......

$(\frac{6}{3} )15 = (2)(15) = 30$

Law Incorporation [45]

Answer:

BC or n=72

Step-by-step explanation:

ABC≈DEF

$\frac{AB}{DE} =\frac{BC}{EF}=\frac{AC}{DF}=k$

$\frac{54}{9} =\frac{n}{12}$

$9n=54*12$

$9n=648$ (then divide both sides by 9.)

A shark weighs 405 kg and 68 grams a second shark weighs 324 kg and 75 g how much more does the first shark weigh in grams than

mariarad [96]

For this case we have to by definition:

1 kg equals 1000 grams

Shark 1:

405 kg and 68 grams

$405 kg * \frac {1000 g} {1kg} = 405,000 grams$

Thus, shark 1 weighs 405,068 grams.

Shark 2:

324 kg and 75 grams

$324 kg * \frac {1000 g} {1 kg} = 324,000 grams$

Thus, shark 2 weighs 324,075 grams.

Subtracting we have:

$405.068 grams-324.075 grams = 80.993 grams$

Thus, shark 1 weighs 80,993 grams more than the second.

Answer:

Shark 1 weighs 80,993 grams more than the second.

Given the cost function C(x) = 0.81x + 60, 420 and the revenue function R(x) = 1.87x, find the break-even point

Viktor [21]

Answer:

x = 57,542.8571

Step-by-step explanation:

C(x) = 0.81x + 60,420

R(x) = 1.87x

At break even point, Cost function and revenue function becomes equal.

-> C(x) = R(x)

-> 0.81x + 60,420 = 1.87x

-> 60420 = 1.87x - 0.82x

-> 60420 = 1.05x

-> x = 60420/1.05

-> x = 57,542.8571

Thus, at break even point x = 57,542.8571
