Answer:
Part A: C
Part B: B
Part C: 15.91
Step-by-step explanation:
first round the 2 numbers by the tenths. Then round the numbers by ones(whohle number). After that, since ther are four sides we do 12.63 + 3.28 + 12.63 + 3.28 which equals to 15.91.
Answer: False
Step-by-step explanation: I believe it would be false. Using the law of sines with the side lengths of 113.29 feet and 125 feet, and the corresponding angels of 25 and 65 degrees, the angle of the light is about 58.29. I believe this would make it false as the angle is incorrect.
Answer:
100 minutes
Step-by-step explanation:
Let
x ----> the number of minutes
y ----> the total cost of the plan
we know that
<em>Cingular Plan</em>
-----> equation A
<em>Verizon Plan</em>
-----> equation B
To find out how many additional minutes will it take for the two plans to cost the same
Solve the system of equations A and B
Solve by graphing
Remember that the solution is the intersection point both graphs
using a graphing tool
The solution is the point (100,84.99)
see the attached figure
therefore
For x=100 minutes
The cost for both plans is $84.99
First, distribute 2 through the parentheses.
Then, take out the parentheses of (x+11)
6x-8+x+11+5
Now collect the like terms.
6x+x=7x
-8+11+5=+8
So the answer is: 7x+8
