Answer:
Length = 3 cm
Width = 1 cm
Step-by-step explanation:
Let the length of rectangle be l and width of rectangle be w.
According to problem,
l = 3w {Length of rectangle is equal to triple the width}
And Perimeter,P = 8 cm
Since, P = 2 ( l + w )
or 8 = 2( l + w)
Plug l =3w in the above perimeter equation.
We get:
8 = 2( 3w + w)
8 = 2(4w)
8 = 8w
or w = 1 cm
Then length ,l = 3w =3 * 1 = 3 cm
Hence length of rectangle is 3cm and width of rectangle is 1cm.
700 rotations
If the radius is 1 foot, the diameter is 2 feet (twice the radius). The circumference of a circle is pi times the radius. Using 22/7 as pi, the circumference of each tire is (22/7)*2 feet. That is the same as 44/7 feet.
If the car is going 4400 feet per minute, the tires will "rotate 4400 feet from the circumference" - if you know what I mean. The tire completes one rotation every 44/7 feet. So, in 4400 feet it will complete (4400)/(44/7) feet. That is equal to 4400*7/44. Put that in a calculator and you get: 700.

Probability of the student taking neither math nor science is 35 / 150 or 0.23
<u>Explanation:</u>
<u />
Given:
Total students = 150
Number of students taking maths = 95
Number of students taking science = 75
Maths + Science = 55
Probability of student taking neither math nor science = ?
Number of students taking only science = 95 - 55
= 40
Number of students taking only maths = 75 - 55
= 20
Number of students taking neither maths nor science = 150 - 40 - 20 - 55
= 35
Probability of the student taking neither math nor science is 35 / 150 or 0.23
