Answer:

Step-by-step explanation:

125 miles / 150 minutes = 300 miles / x       Criss multiply

Notice that the numerators both have the same units -- miles. Proportions should always be set up that way.

125 x = 150 * 300                  Combine the right

125x = 45000                        Divide by 125

x = 45000/125

x = 360 more minutes which is 6 hours.

(3b + 12 ) divided by 2 =30 Whats is b ?
denpristay [2]

b=16 , First you multiply 30 by 2 to see what sum you need for the numerator. Then you subtract the 60 that you get by the 12 and get 48. So 3 multiplied by b should give you 48. So you just divide 48 by 3 and get 16.

The value of a small airplane depreciates exponentially every year after it is purchased. The value, in thousands of dollars, a(
ratelena [41]

Using an exponential function, it is found that the number 131.5 represents the initial value of the plane, in thousands of dollars.

<h3>Exponential function:</h3>

A decaying exponential function is modeled by:

A(t) = A(0)(1 - r)^t

In which:

  • A(0) is the initial value.
  • r is the decay rate, as a decimal.

In this problem, the function for the value of the airplane after t years is given by:

A(t) = 131.5(0.8)^t

Hence A(0) = 131.5, which means that the number 131.5 represents the initial value of the plane, in thousands of dollars.

The measures of the angles of a triangle are shown in the figure below. Solve for x.
slavikrds [6]

Answer:

x=13

Step-by-step explanation:

We add all the numbers together, and all the variables

6x-78

We move all terms containing x to the left, and all other terms to the right

6x=78

x=78/6
