Answer:
Step-by-step explanation:
Jim will save $14.20
To calculate this we use multiplication, multiply $71.00 with 20% which in decimal form
Comes to .20.
The end result is $14.20.
Answer:
47
Step-by-step explanation: the angles add up to 180 180-133=47
Answer:
(c) 3360
Step-by-step explanation:
Given
The above arithmetic series where:
--- first term
--- the common difference (18 - 12 = 6)
--- The last term
Required
The value of the series
First, we calculate n using:
This gives:
Collect like terms
Divide both sides by 6
Make n the subject
The sum of the series is:
So, we have:
By Green's theorem,
where is the region with boundary , so we have
Answer:
Step-by-step explanation:
B=3x-2
C=12x+2
D=B=3x-2 (Vertically opposite angles)
A=?
Now; we know, A+B+C+D=360 deg.
=>A=360-(B+C+D)
=360-(3x-2+12x+2+3x-2)
=360-(18x-2) ----[1]
B+C=180 deg. (linear pair)
=> 3x-2+12x+2=180
=> 15x=180
=> x=180/15
=12 ---[2]
subsitute [2] in [1];
=> A= 360-(18x-2)
= 360-(18*12-2)
= 360-(116-2)
= 360-214
= 146 deg.
So, the correct answer is (D).
Hope the answer is useful.
