10y+28 is equivalent to 5(2y+8)-12
-1 <span>± </span><span><span>√61 / 6. Negative 1, plus or minus square root of 61 divide by 6</span></span>
<span>There are 366 days in a leap year
In a week there are 7 days, so total no of days= 7*52=364 days.
Here 52 represents number of weeks.
Now last two days can be combination of two days say like Monday and Tuesday or Tuesday and Wednesday and so on.
So in total 7 combinations are possible.
Out of there can be 3 combinations containing Thursday or Friday.
Hence, the probability is 3/7.
Hence the answer is 3/7</span>
So first lets do the fraction: 68/80. This is probably the most simple part, but if you want to simplify it you could go all the way down to 17/20.
For decimalthen you divide 68 by 80, and that is .85! Then to get your percentage, you multiply it by 100 and end up with 85%.
Percent: 85%
Fraction: 68/80 or 17/20
Decimal: 0.85
Hope this helps!
Answer: 4
Step-by-step explanation:
( f o g ) (3) means f(g(3)) so...
First: plug 3 into g(x) = x^ (2-1)
3^ (2-1) is 3^1 = 3
Next: plug 3 into f(x)= 2^(x-1)
2^(3-1) is 2^(2) > 2×2 = 4
