Answer:
b
Step-by-step explanation:
you can use a calculator, or this way of thinking about it :
the sqrt of 49 is 7. so rt46 is too small, and rt51 may be too big. rt50 is closer to rt49 ( 7's square) than rt47. so it is rt50

Answer:
21 coins of ₹2
Step-by-step explanation:
Let x represent the number of ₹2 coins, and y the number of ₹5 coins. Then the total value of the coins is ...
2x +5y = 77
and the relationship between numbers of coins is ...
x = 3y
Substituting for x, we have ...
2(3y) +5y = 77
y = 77/11 = 7 . . . . simplify, divide by the coefficient of y
x = 3(7) = 21 . . . . find x from the second equation
Ram has 21 of the ₹2 coins.
<span>the unit rate corresponds to the proportional relationship

Answer:
0.25
Step-by-step explanation:
This is the question on conditional probability
Let A - the quadrilateral has four right angles
B - the quadrilateral has four equal side lengths
Required probability = P(B/A)
By definition of continuous probability


P(A) = 
Hence given probability =
