25.5125 como lo conmvierto a sexigesimal

25.5125 = 25 + 5125 / 10⁴ = 25 + 41 / 80

(41 / 80) / 60⁻¹ = 2460 / 80 = 123 / 4 = 30.75

30.75 = 30 + 75 / 10² = 30 + 3 / 4

(3 / 4) / 60⁻² = 180 / 4 = 45

→   25.5125₁₀ = [25].[30][45]₆₀

For 1 flavor there are 9 topping

Therefore, for 5 different flavors there will be 5*9 choices

No of choices= 5*9

=45

For every 8 cars there are 7 trucks

Therefore,

Cars:Truck=8:7

Answer is B)8:7

The solution is in the following image

y=2x+15

where y=Value of coin

x=Age in years

Value of coin after 19 years=2*19+15

=$53

Therefore, Value after 19 years=$53

F=ma

where F=force

m=mass

a=acceleration

Here,

F=4300

a=3.3m/s2

m=F/a

    =4300/3.3

    =1303.03kg

Approximately it is aqual to 1300kg

The solution is given in the image below
