Subtract 28 from 49 which is 21 picked in the second hour
Answer:
A = 12 units ^2
Step-by-step explanation:
The area of the trapezoid is found by
A = 1/2 (b1+b2)h
b1 = 2
b2 = 4
h = 4
I found these by looking at the graph
A = 1/2(2+4) 4
A = 1/2(6*4)
A = 12 units ^2
Option C: 6 is the value of 
Explanation:
The given expression is 
We need to determine the value of 
To find the value of
, let us substitute
in the given expression.
Thus, substituting
in the expression, we have,

Adding the terms, we get,

Since, we know the absolute rule that
and the simplified expression is of the form
, let us apply the absolute rule in the simplified expression.
Thus, we have,

Thus, the value of
is 6.
Hence, Option C is the correct answer.
1 time=2mins
xtimes=30mins
30/2 ×1= 15.
Therefore it can be completed 15 times in 30mins
