Width=x
length=2x+5
perimeter of a rectangle=2(length)+2(width)
We can suggest this equation:
88=2(2x+5)+2x

88=4x+10+2x
6x=88-10
6x=78
x=78/6
x=13

width=x=13
length=2x+5=2(13)+5=26+5=31

Answer: the width would be 13 cm.

The following equation represents the number of fish in a pond, F(x), after x number of weeks. F(x) = 500 (1.2)x. How many fish
Shalnov [3]

Answer:

1) d. 2400

2) d.4200

Step-by-step explanation:

As per given data:

F(x) represents number of fish

x represents number of weeks

Relation between F(x) and x is given as

F(x)= 500 (1.2)x

Now part 1:

How many fish are in the pond after 4 weeks=?

x=4

Putting in given equation  F(x)= 500 (1.2)x

F(x)= 500(1.2)(4)

     = 2400

Now part 2:

How many fish are in the pond after 7 weeks?

x=7

Putting in given equation  F(x)= 500 (1.2)x

F(x)= 500(1.2)(7)

     = 4200 !

lidiya [134]
Data:
v (volume) = ?
h (height) = 3 ft
r (radius) = 1.5 ft
Adopting: \pi \approx 3.14

Formula:
V = h* \pi *r^2

Solving:
V = h* \pi *r^2
V = 3*3.14*1.5^2
V = 3*3.14*2.25
\boxed{\boxed{V=21.195\:cubic\:feet}}\end{array}}\qquad\quad\checkmark
