Answer:
1:4:12
Step-by-step explanation:
George = x
Alex = 12 + x
Carl = 3(12 + x) = 36 + 3x
x + 12 + x + 36 + 3x = 68
5x + 48 = 68
5x = 20
x = 4
George = x = 4
Alex = 12 + x = 12 + 4 = 16
Carl = 36 + 3x = 36 + 3(4) = 48
4:16:48 = 1:4:12
The ratio is 1:4:12.
Answer:
Here we are given with the numbers 4 16 36 64 100
So in these kind of questions we have to find what common pattern is prevailing so in this one:
Subtracting every no from it's succeeding no gives a difference and those respective differences are forming pattern as follows:
16–4=12
36–16=20
64–36=28
100–64=36
So we have a new series 12 20 28 36 in this Subtracting every no from it's succeeding no gives a difference of 8 now in the latter series continues with the same pattern of difference of 8 and the series proceeds with next numbers 44 52 60 now these no gets added in the first original series as described as follows :
100+44=144
144+52=196
196+60=256
So the next 3 numbers are 144,196,256
In all right triangles, the ratio between a leg and the hypothenuse is the sine of the angle opposite to the leg.
So, in your case, we have
In order to find XY, we have
So, the ratio for the sine is
Compound interest formula = total = P(1+r/n)^nt
Where P = is the intial amount invested
r is the interest rate, n is the number of compounding periods per year and t is the number of years.
Total = 15000(1+0.065/1)^7
Total = 15000(1.065)^7
Total = $23,309.80
