to rent a certain meeting room, a college charges a reservation fee of $18 and an additional fee of $6 per hour. The chemistry club wants to spend at most $72 on renting the room. what are the possible numbers of hours the cemetery club could rent the meeting room? use t for the number of hours. write your answer as an inequality solved for t.

Answers

Answer:

t ≤ 9 hours

Step-by-step explanation:

Reservation fee = $18

Additional fee per hour = $6

Let x = number of hours

At most in inequality means ≤ less than or equal to

The inequality is

18 + 6t ≤ 72

6t ≤ 72 - 18

6t ≤ 54

t ≤ 54/6

t ≤ 9 hours

Convert the equation to Standard Form.

y=2(x+1)^(2)-4

Answers

Answer:

y = 2x^2 + 4x - 2

Step-by-step explanation:

y=2(x+1)^(2)-4 is in vertex form. We want the same equation in standard form, which looks like y = ax^2 + bx + c.

Perform the indicated multiplication (squaring of x + 1):

y = 2(x^2 + 2x + 1) - 4, or

y = 2x^2 + 4x + 2 - 4, or

y = 2x^2 + 4x - 2 This is in the standard form of a quadatic.

which is longest 90 centimeters, 40 meters, 30 kilometers, 10 meters, 40 millimeters

Answers

Answer:

30 Kilometers

Step-by-step explanation:

The longest measure from the given measures is 30 kilometers.

A no. of measurement values are given in the question.

We have to find out which is the longest from them.

What is the meaning of unit conversion ?

A unit conversion is done to express the same property as a different unit of measurement.

As per the question ;

Some measures i.e., 90 centimeters, 40 meters, 30 kilometers, 10 meters, 40 millimeters are given.

Let's check which is the longest by converting them all in same units say centimeters.

So ;

a) 90 centimeters

= 90 centimeters

b) 40 meters

= 40 × 100 centimeters

= 4000 centimeters

c) 30 kilometers

= 30 × 1000 meters

= 30000 × 100 centimeters

= 3000000 centimeters

d) 10 meters

= 10 × 100

= 1000 centimeters

e) 40 millimeters

= 40 / 10 centimeters

= 4 centimeters

So ; the longest is 30 kilometers.

Thus , the longest measure from the given measures is 30 kilometers.
