100/20+5*(9+21)2=?
100/20 +5 * (9+21)^2 = 4505
You use the 1/x button when there is a decimal, whatever number comes up, put 1 over that number.
EXAMPLE:
1/(.004) = 250
So, .004 is 1/250
Thx! :)
-(121^.5) = -11
OR
(-121)^.5 = Error: not real
1. 40% of 75 is 30
75*.4=30
2. 30 is 33% of 90
90*.333...=30
3. 55 is 20% of 275
55/.2 = 275
4. She will have to sell 114 boxes because 95*.2=19
95+19=114.
The function is 8x
Substituting 7 for x, it would equal 56
7*8=56
Let's use 3.14 for pi.
3.14*12 = 37.68
So the circumference is 37.68 ft
EDIT: Hayley, you beat me to it. +5
Hayley, that would be 7 divided by 2 divided by 3.
Instead do 7 2/3
Or make it an improper: 23/3
Or make it a decimal: 7.6666......
So, you eat 6/12 of a pizza and your friend eats 4/12
6/12+4/12=10/12
12/12-10/12=2/12
You have 2/12 of the pizza left, or 1/6 of it left
So we have 2.5 hours and 80 miles per hour.
80 * 2=160
80*.5=+40
200
If you kept a constant speed of 80 miles an hour, you will have traveled 200 miles in 2.5 hours.
