9 tens 10 ones equals
=> 9 x 10 + 10 x 1
=> 90 + 10
=> 100.
Here asked for the value of 28 tens
=> 28 x 10 = 280.
A square and a rectangle each have 4 right (90 deg) angles.
Both square and rctangle have 4 sides and 4 angles, but the only difference is square is a rectangle with all sides equal.
In the real numbers, zero does not have a reciprocal because no real number multiplied by 0 produces 1 (the product of any number with zero is zero).
Hence, 0 doesn't have any multiplicative inverse.
Given that 50 paise and 25 paise coins are in the ratio of 7:3, they can be either 7 & 3 or 14 & 6.
As total 20 coins also includes Rs. 1 coins, so 50 paise & 25 paise coins are 7 & 3 respectively & Rs. 1 coins are 10.
Total amount = (100x10) + (50x7) + (25x3)=1425 paise or Rs.14.25.
Total number of cards = 1500
total columns = 45
so, total punches=1500 x 45 = 67500
for 1 hour if we make 9000 punches,
we require 67500/9000 = 7.5
so 7hours:30mins.
From the trial and error method of division,
201 is divisible by 3
205 is divisible by 5
203 is divisible by 7
Hence, after eliminating three options, remained is 211 and is divisible by only 1 and itself.
Therefore, 211 is the smallest prime number greater than 200.
Frequency is what means how many times the event occurs in the same period.
The distance around a figure is called as Perimeter of that figure. For example, rectangle perimeter is 2(L+B) and where as perimeter of square is '4S'.
A segment with endpoints on the circle is a chord. The longest chord of a circle is a diameter of the circle.
