ANTONII [103]3 years ago
7 0

Answer:

The answer is 30

Step-by-step explanation:

The definition of an average is the sum of elements/number of elements.

Since we know the number of elements and their average, we can solve for the sum by multiplying 5*6.

This results in 30.

An airplane is flying 35,000 feet above sea level .the airplane starts to descend at a rate of 2,500 feet per minute .let m be t
marusya05 [52]

Answer:

35000 - 2500m

Step-by-step explanation:

Height of the airplane before it starts descending = 35,000 feet

Rate of descend = 2500 feet per minute

This means for every 1 minute the height of airplane is decreasing by 2500 feet. So, for every "m" minutes the height of airplane will decrease by 2500m feet.

Let h(m) denotes the height of the airplane after m minutes. The equation for h(m) can be set up as:

Height of airplane at m'th minute = Original Height - Distance descended in m minutes

So,

h(m) = 35000 - 2500m

This expression describes the height of airplane after any number of minutes(m).

Jamie runs a math-tutoring program. For each student, she charges an enrollment fee of $63.00 plus $18.00 per hour of tutoring.
Tamiku [17]

Answer:

The best and most correct answer among the choices provided by your question is the third choice or letter C. The total number of hours is 17.

For h>7

C=210+20(h-7)

C=210+20h-140

C=20h+70, h>7

20h=340

h=17 hours

A company sells widgets. The amount of profit, y, made by the company, is related to
tiny-mole [99]

Answer:

In order to make the maximum profit, the company should sell each widget at (the currency isn't given, so I'll be assuming USD) $36.

Step-by-step explanation:

The amount of profit <em>y</em> made by the company from selling each widget at <em>x</em> price is modeled by the equation:

y=-x^2+72x-458

Since this is a quadratic with a negative leading coefficient, its maximum will occur at its vertex point. We want to find the price that the widget should be sold to make the maximum profit. So, we want to find the <em>x-</em>coordinate of the vertex. This is given by the formula:

\displaystyle x=-\frac{b}{2a}

In this case, <em>a</em> = -1, <em>b</em> = 72, and <em>c</em> = -458. Substitute and evaluate:

\displaystyle x=-\frac{72}{2(-1)}=36

In order to make the maximum profit, the company should sell each widget at (the currency isn't given, so I'll be assuming USD) $36.
