Answer:

42 ft.

Step-by-step explanation:

Area of a rectangle = L × B

Where,

L = length

= 9 ft

B = width

108 = 9B

Therefore,

B = 12 ft

Perimeter of rectangle = 2 * (L + B)

= 2 * (12 + 9)

= 42 ft.

3x + 4y = 8<br> How do I solve this
dimaraw [331]

Answer:

y= (-3x+8)/4

x = (-4 +8)/3

Step-by-step explanation:

3x + 4y = 8

-3x               -3x

4y = -3x +8     divide ALL by 4

y= (-3x+8)/4

3x + 4y = 8

    -4y          -4y

3x = -4 +8     divide ALL by 3

x = (-4 +8)/3

The number of ferryboat trips r(c) needed to transport c cars in 1 day can be found using the function f(c)=c/20. If there are n
xz_007 [3.2K]
<h2>Hello!</h2>

The answer is:

The range of the given function, f(c) is

f(c)\leq 250

<h2>Why?</h2>

To solve the problem we need to remember that a function is a relationship between an input usually called "x" (domain) and an output, usually called "y" and it's also the range of the function.

f(x)=y

We are given a relationship (a function) between the ferryboat trips "c" and the number of cars transported per day.

f(c)=\frac{c}{20}

Also, we know that there are not more than 5000 cars transported by the ferryboat, so, let's make this value our input, in order to find the output (range) of the given function.

So, if

c=5000

Evaluating, we have:

f(5000)=\frac{5000}{20}=250

Hence, the range of the function knowing that there are not more than 5000 cars transported by the ferryboat (daily) the range is all the numbers that are less or equal to 250.

f(c)\leq 250

Have a nice day!

PLEASE HELP ME!!
gizmo_the_mogwai [7]

Answer:

$4375

Step-by-step explanation:

Add up all the sides to get the perimeter:

240 + 285 + 450 + 450 + 450 = 1875 ft

Convert ft into yards:

3 ft = 1 yard

1875 ft = 625 yards

________________________________

(625 yards)($27) = $4375
