(180-x)-2(90-x)= 53
Remember that complimentary angles add to 90 and supplementary angles add to 180.
180-x-180+2x=53
x=53
Final answer: The angle is 53 degrees.
Answer:
The indifference point is 140 minutes.
Step-by-step explanation:
Giving the following information:
Plan A costs $ 25 plus an additional $0.10 for each minute of calls.
Plan B costs $18 plus an additional $0.15 for each minute of calls.
<u>First, we need to establish the total cost formula for each plan:</u>
<u />
Plan A= 25 + 0.1*x
Plan B= 18 + 0.15*x
x= number of minutes
<u>Now, to calculate the indifference point, we equal both formulas and isolate x:</u>
25 + 0.1x = 18 + 0.15x
7 = 0.05x
140=x
The indifference point is 140 minutes.
<u>Prove:</u>
Plan A= 25 + 0.1*140= $39
Plan B= 18 + 0.15*140= $39
table A from 2-3 minutes it rose 64.9-61.3 = 3.6
from 3-7 it rose 79.3 -64.9 = 14.4 = 3.6 degrees per minute
Table B needs to raise faster than 3.6 per minute
64.4 -61 = 3.4
64.6 - 61 = 3.6
64.3 -60.6 = 3.7
so the 3rd table is correct
Answer:
D) h(x) = (x-2)^2 (x+4)(x-1)
Step-by-step explanation:
I had this question on a recent test and I got it right
I hope this helps! :)
C= πd, where C means circumference and d means diameter. 0.75 is the diameter of the pond, so 3.14 × 0.75 gives you 2.355mi.
You walked the diameter while your friend walked the HALF circumference. (2.355÷2) -0.75 is your answer
