Answer:
25 months
Step-by-step explanation:
Plan A : $70 per month
Plan B : $50 per month + $500 as a one time cost.
So for A $70 a month would take 8 months to be at least $500
And for B it in those 8 months it would cost you $900
But we have to keep going up until they are equal
25*70 = 1750
(25*50) = 1250+500=1750
So yes 25 months is correct
Answer:
5√3 or
8.66 to the nearest hundred.
Step-by-step explanation:
Length of each line of the triangle = 30/3 = 10.
The altitude, side and 1/2 base make a right triangle.
So by Pythagoras:
10^2 = 5^2 + h^2 where h = altitude.
h^2 = 100 - 25 = 75
h = √75 = 5√3.
15 x 6 = 90 (total area of the door)
1 x 9 = 9 (area of the panel)
90 - 9 = 81 (area of the white portion)
Answer:
The third piece must be 14.4 inches
Step-by-step explanation:
We use the triangle inequality theorem to get the third side
using the theorem, it must be that the sum of the two will be greater than the length of the third side
Hence we have it that;
a + b > c
6.5 + 8.1 > c
14.6 > c
So what this mean is that the third length is less than 14.6
the reasonable answer out of the options is thus 14.4 inches
reason for this is that the last two options will also not follow the inequality theorem
