6 cats/kittens were adopted.

Step-by-step explanation:

Given,

Number of cats/kittens at the event = 44

Number of cats/kittens adopted = x

Number of cats/kittens returned = Twice returned as adopted = 2x

New total = 50

We will subtract the adopted and add the returned cats/kittens.

Total cats/kittens at event - adopted + returned = New total

$44-x+2x=50\\44+x=50\\x=50-44\\x=6$

6 cats/kittens were adopted.

The following table represents a grouped frequency distribution of the number of hours spent on the computer per week for 59 stu

Marysya12 [62]

The value of the lower class limit of the 3rd class is; 11.0

<h3>What is the lower class Interval?</h3>

The lower class limit is lowest value of that class interval while upper class limit is highest value of that class interval.

Hours Number of Students

0.0–5.4 12

5.5–10.9 16

11.0–16.4 14

16.5–21.9 11

22.0–27.4 6

Now, the third class interval is 11.0–16.4 and from definition of lower class limit, we can say that the lower class limit of the 3rd class is; 11.0

The perimeter of a rectangle is 72 cm. The length is 3 more than twice the width What

solmaris [256]

<h3>Solution</h3>

Given :-

Perimeter of rectangle = 72 cm
The length is 3 more than twice the width.

Find :-

Dimensions of rectangle

<h3 /><h3>Explantion</h3>

Using Formula

$\boxed{\underline{\tt{\red{\:(perimeter_{rectang}\:=\:2\times (Length+Width)}}}}$

Let,

Length of Rectangle = x cm
Breadth of Rectangle = y cm

According to question,

==> perimeter of Rectangle = 72

==> 2(x+y) = 72

==> x + y = 72/2

==> x + y = 36_________________(1)

Again,

==> x = 2y + 3

==> x - 2y = 3__________________(2)

Subtract equ(1) & equ(2)

==> y + 2y = 36 - 3

==> 3y = 33

==> y = 33/3

==> y = 11

keep in equ(1)

==> x - 2×11 = 3

==> x = 3 + 22

==> x = 25

<h3>Hence</h3>

Length of Rectangle = 25 cm
Width of Rectangle = 11 cm
