Answer:

8 centimeters of the route on map

Step-by-step explanation:

Let us plan out our steps, and solve for each:

1. Knowing that we have to determine the cm on the map, let us first convert

1.2 kilometers ⇒ centimeters:

1.2 km = 120,000

2. Given the information, let us create a proportionality as such:

1 = 15,000 ⇒ x - cm of the route on the map

x 120,000

2. Now let us cross multiply, and solve through simple algebra:

15,000 * x = 120,000

x = 8 centimeters of the route on map

Solve using a system of equations. Tickets to a local movie were sold at $6.00 for adults and $4.50 for students. If 110 tickets

Marrrta [24]

Answer:

The number of adults tickets is 80 and the number of students tickets is 30

Step-by-step explanation:

Given as :

The tickets price for adults = $6.00

The tickets price for students = $4.50

Total number tickets were sold = 110

Total Price of 110 tickets = $615.00

Now,

Let The number of adults tickets sold = A

The number of students tickets sold = S

So, according to question

A + S = 110

And 6 A + 4.5 S = 615

Or, 6 A + 6 S = 660 .....1

6 A + 4.5 S = 615 ......2

Solving the equations

( 6 A + 6 S ) - ( 6 A + 4.5 S ) = 660 - 615

Or, ( 6 A - 6 A ) ( 6 S - 4.5 S ) = 45

or, ( 6 S - 4.5 S ) = 45

or, 1.5 S = 45

∴ S = $\frac{45}{1.5}$

I,e S = 30

Put the value of S in eq 1

So, 6 A + 6 × 30 = 660

Or, 6 A = 660 - 180

Or 6 A = 480

∴ A = $\frac{480}{6}$

I.e A = 80

Hence The number of adults tickets is 80 and the number of students tickets is 30 . Answer

David estimates that he will have expenses totaling $24,870 for one year of college, He will receive$7,560 in grants. Howmuch wi

noname [10]

Since there are 2 semesters per year we have:

(1/2)(24,870 - 7,560) = $8,655

David would have to contribute $8,655 per semester.

For a function f(x), the difference quotient is x + one-half h + 15. Which statement explains how to determine the average rate

Paraphin [41]

The average rate of change of f(x) from x = 5 to x = 8 would be gotten by; B: Substituting 5 for x and 8 for h in the expression x + one-half h + 15

<h3>How to used difference quotient to find average rate of change?</h3>

The difference quotient is defined as a measure of the average rate of change of a function over an interval.

The limit of the difference quotient which is the derivative is the instantaneous rate of change.

This differential quotient in calculus is usually expressed as;

[f(x + h) - f(x)]/h

We are given the differential quotient as;

f(x) = x + ¹/₂h + 15

Thus, the average rate of change of f(x) from x = 5 to x = 8 would be gotten by;

Substituting 5 for x and 8 for h in the expression x + one-half h + 15
