A field is a rectangle with a perimeter of 1100 feet. The length is 300 feet more than the width. Find the width and length of t
Wewaii [24]

Answer:

Step-by-step explanation:

perimeter of rectangle = 1100

let breadth be x

length = 300 + x

perimeter of rectangle = 2(l + b)

1100 = 2(300 + x + x)

1100 = 2(300 + 2x)

1100 = 600 + 4x

1100 - 600 = 4x

500 = 4x

500/4 = x

125 = x

therefore breadth is 125 feet

length = 300 + 125

=425 feet

Let f(x)=-3x-7 Abe g(x)=4x-5 find (f•g)(-3)
LiRa [457]

Answer:

272

Step-by-step explanation:

note that (f • g)(x) = f(x) × g(x) = (3x - 7)(4x - 5)

To evaluate substitute x = 3 into (3x - 7)(4x - 5)

(f • g)(- 3) = (- 9 - 7)(- 12 - 5) = - 16 × - 17 = 172

$50 is 25% of what amount
balandron [24]

Answer:

$200

Step-by-step explanation:

You divide to find the answer

50 divided by 0.25

and you will get 200.

So $50 is 25% of 200

For a double check do 50/200

50/200 = 25/100

25/100 = 1/4

1/4 = 0.25

0.25 = 25%

So the final answer is 200.

Hope it helped! My answer is expert verified.
