Option C: is the value of a and b
Explanation:
Given that the expression
We need to determine the value of a and b
Let us consider the term and take the prime factorization of the term 648
Thus, we have,
648 divides by 2,
324 divides by 2,
162 divides by 2,
81 divides by 3,
27 divides by 3,
9 divides by 3,
Thus, we have,
Therefore, equating the powers of 2 and 3, we get,
Hence, the value of a and b is 3 and 4
Thus, Option C is the correct answer.
Answer:
The speed of the cyclist is 10 miles per hour .
Step-by-step explanation:
Given as :
The distance cover by cyclist = = 20 miles
The distance cover by biker = = 6 miles
The speed of biker = = s mph
The speed of cyclist = = 7 + s mph
The time taken by both cyclist and biker = t hour
Now. Distance = Speed × Time
So, =
× t
Or, 20 = s × t
Or, t = .....1
And ,
=
× t
or, 6 = s t
Or, t = ....2
From Eq 1 and 2
I.e =
Or, 20 s = 6 ( 7 + s )
Or, 20 s - 6 s = 42
Or, 14 s = 42
∴ s =
I,e s = 3 miles per hour
So, The speed of biker = = s = 3 miles per hour
And The speed of cyclist = = 7 + s = 7 + 3= 10 miles per hour
Hence The speed of the cyclist is 10 miles per hour . Answer
Answer:
1/3 is the slope and if it’s less than or greater to that, then the bottom half of the graph is shaded in.
