The total number of 3 digit even numbers is 450
Step-by-step explanation:
Step 1 :
We need to determine the number of 3 digit numbers which is even and the leftmost digit is not zero .
The 3 digits with left most digit not equal to zero starts from 100 and goes up to 998
If we consider only the even 3 digit numbers in this interval, this would form an arithmetic progression with the first number a = 100 and the common difference d = 2.
Step 2:
The last number l in this series is 998 .
So we have
a = 100
l = 998
d = 2
The nth term in the arithmetic progression is given by a + (n-1) d
so substituting the above values we get
100 + (n-1) 2 = 998
2n = 900 => n = 450
Step 3 :
Answer :
The total number of 3 digit even numbers is 450
Answer:
9.13 cm^2.
Step-by-step explanation:
The diagonal of the square = the diameter of the circle.
The length of the diagonal = 4√2 cm (because we have a 45-45-90 triangle), so the radius of the circle is half of this = 2√2 cm.
The area of the shaded part = area of the circle - area of the square
= π (2√2)^2 - 4^2
= 25.13 - 16
= 9.13 cm^2.
Answer: Fractions equivalent to 1/2 are 2/4, 3/6, 4/8, 5/10, 6/12 ... Fractions equivalent to 1/3 are 2/6, 3/9, 4/12, 5/15, ... Fractions equivalent to 1/4 are 2/8, 3/12, 4/16, 5/20,
C is the answer. It is the answer because the answer must be on the line or in the shaded area.
