Answer:
A rational number is an integer that either doesn't have a decimal or has a decimal that either repeats or terminates (ends). Basically, if these square roots come out to be an integer, they're rational.
The first one comes out to be 42.6028168083, so obviously not rational.
The second one comes out to be 55, so it is rational.
Consider the provided numbers.
√1,815 and √3,025
The value of √1,815 = 48.60281680.....
The value of √3,025 = 55
Now consider the definition of rational and irrational number.
Rational number: A number is said to be rational, if it is in the form of p/q. Where p and q are integer and denominator is not equal to 0.
Irrational number: A number is irrational if it cannot be expressed be expressed by dividing two integers. The decimal expansion of Irrational numbers are neither terminate nor periodic.
The number √1,815 is an irrational number as the decimal expansion of numbers is neither terminate nor periodic.
The number √3,025 is a rational number as it is in the form of p/q.
Answer:
314-178=136 the remainig piece of board is 136
Step-by-step explanation:
so first u subtract 314 with 178 becuase it said that he cut off so u subtract then after u subtract u get the answer 136
Let the numbers be n, n+2, n+4
Sum equals too= 13+2(n+4), which is 2n+21
a) Equation--> n+n+2+n+4= 2n+21
b) Solution--> 3n+6= 2n+21
=> n= 15
c) Second number--> 17 (15+2)
Third number--> 19 (15+4)
d) 15+15+2+15+4=30+21
=> 51= 51
So, the equation is true.
And pls mark me brainliesttt :)))
Answer:
No solution
Step-by-step explanation:
Speed of Jordan while driving from his home = 56 mph
After Jordan travels 2 miles then Roman started from his house.
Speed of Roman while driving after leaving home= 60 mph
Let after t hours they meet.
And let they cover the distance =d i.e point at which meet.
After time t distance covered by Jordan= 56 t +2
Roman has to cover the distance to catch Jordan= 60 t
A.T.Q
⇒ 60 t=56 t + 2
⇒4 t=2
⇒t=1/2
So, when d = 56×1/2+2=28+2=30 miles
Roman will catch Jordan.
From the above four solutions ,( C.) d = 56 t ,d = 60 t – 2 , Satisfies the above criteria.
So C is the correct answer.
