Area = length x width

The length is equal to 9 feet and the width is equal to 7 feet.

So you would have to multiply 9 feet by 7 feet to get 63 square feet.

I think you may have mixed up area with perimeter. Perimeter is when you are adding all of the side lengths together. So the perimeter would have been 2(9) + 2(7) = 18 + 14 = 32 units. Remember the units for perimeter is not square units and only area would have square units, so that should give you a hint as to what you should do.

Finger [1]

Answer:

a. The Mexican Airline offers a better deal for 9 students to travel.

b. 10 students

Step-by-step explanation:

a. The Mexican Air airline offers a round trip airfare of $250 per person.

So, for 9 students the fare will be total $(250 × 9) = $2250

Now, the Fiesta airline offers a round trip airfare of $150 per person if the club agrees to pay a one-time group rate processing fee of $1000.

So, for 9 students the total fare will be = $[1000 + (150 × 9)] =$2350.

Therefore, the Mexican Airline offers a better deal for 9 students to travel. (Answer)

b. Let for x students both the airline offers the same total costs.

Then we can write

250x = 1000 + 150x {From the conditions given}

⇒ 100x = 1000

⇒ x = 10

So, if the number of students is 10, then only both the airlines will take same fare. (Answer)

a rectangular prism has a length of 2 3/4 feet, a width of 4 1/2 feet, and a height of 6 inches. what is the volume of the prism

Nataliya [291]

Answer:

10692 cubic inches

Step-by-step explanation:

Since we are told to give the units in inches, let's convert the two values which are in feet.

1 ft= 12 inches

thus,

length 2.75 ft. = 33inch

breadth 4.5 ft. = 54 inch

and height is 6 inches.

Volume of a cube= length × width × height

= 33 × 54 × 6

= 10692 cubic inches

(x+3 ; y-5)

If you have (-2 ; 3) that means x = -2 and y = 3 so:

(-2+3 ; 3-5) = (1 ; -2)

Offering 20 points for this one need asap

kirill115 [55]

Answer:

y = 3x+.5

Step-by-step explanation:

We know the y intercept (the value when x=0) is .5

We can find the slope from 2 points

(0,.5) and (1,3.5)

m = (y2-y1)/ (x2-x1)

= (3.5-.5)/(1-0)

= 3/1

= 3

We can use y = mx+b since we know the slope and the y intercept

y = 3x+.5
