Step-by-step explanation:
he doesnt round off his value,,,he leaves divided the values wrongly ,,he never left his work in 4 significant figures
(5.1 * (10-3)) + (3.2 * (10-3))
(5.1 * 7) + (3.2 * 7)
35.7 + 22.4
58.1
So 58.1 is the final answer! Hope this helps!
This is the concept of functions. We are required to calculate for the total cost of tickets if 27, 39 and 43 people attended a concert whose cost was represented by C=10n+26.
To solve for this we substitute the each values in the function as follows;
When n=27
C(27)=10*27+26=296
When n=39
C(39)=10*39+26=416
When n=43
C(43)=10*43+26
=456

Step-by-step explanation:
Formulas to know:
- Area of a circle:
- Circumference of a circle:
Since we know the circumference, we can use formula for the circumference of a circle to find the circle's radius:
Now we can plug in 
into the formula for an area of a circle:
2800 + 0.08s = 3300 + 0.06s
0.08s = 0.06s = 3300 - 2800
0.02s = 500
s = 500 / 0.02
s = 25,000 <==
