Please <3 my Answer B )
Answer:
B. Square root of 25
Step-by-step explanation:
It is a whole number.
Thus, it is not an irrational number.
The square root of 25 is equal to 5
Therefore
An irrational number is a number that cannot be written as a ratio of two integers. It is a non-terminating and non-repeating decimal.
Answer:
212 ft is the perimeter
Step-by-step explanation:
well, we know that 1ft³ = 7.48 gallons, alright, we have a volume in gallons and a diameter in feet, so if we were to use the diameter in feet to get the volume what we would end up will be a volume in ft³, so let's convert firstly the gallons to ft³ then
![750g\cdot \cfrac{ft^3}{7.48g}\implies 750g\cdot \cfrac{ft^3}{~~\frac{748}{100}g~~}\implies \cfrac{18750}{187}ft^3](https://tex.z-dn.net/?f=750g%5Ccdot%20%5Ccfrac%7Bft%5E3%7D%7B7.48g%7D%5Cimplies%20750g%5Ccdot%20%5Ccfrac%7Bft%5E3%7D%7B~~%5Cfrac%7B748%7D%7B100%7Dg~~%7D%5Cimplies%20%5Ccfrac%7B18750%7D%7B187%7Dft%5E3)
why do I use a fraction? for the sake of not losing value in the rounding, so let's use the fraction for the volume of a right-circular cylinder

p-2-3 =-8+3+5p-4p
Let us try to simplify this equation,
combining like terms -2-3 on left and 5p-4p and -8+3 on the right side,
p-5=-5+p
Since we have +p on both sides , so both of them will get cancelled,
-5=5
Here we have no variable left and also -5 is not equal to 5.
so answer will be no solution for the given equation.
