Answer:
1
Step-by-step explanation:
Given
← substitute x = 5 and y = 7 into the expression
=
=
= 1
There's 24 hours in a day
so 24/100 = 0.24 < that is the percentage per hour
first eating - %10. 0.24x10= 2.4hrs eating
free time - 15% 0.24x15= 3.6hrs of free time
homework - 10% 0.24x10 = 2.4hrs of homework
school - 25% 0.24x25= 6hrs of school
and sleeping = 40% 0.24x40=9.6hrs of sleep
add them(hours) all up and you'll get 24!
1) you have to use PEMDAS.
2) 0.2^4+2.1•0.5^3 **solve exponents first**
.0016+2.1•0.125
.0016+0.2625=.2641
2) your answer is .2641
