No Calculator: What is the
`sqrt(16)`
4
100
? = 81
100
25 - 4*5 = 25-20 = 5
100
If the rock fell for 3 seconds, how far did it fall?
`d=15t^2 `
d = 15*9=135 feet
100
Solve for x:
`2x + 8 = 20`
6

No calculator: What is the
`sqrt(64)`
8
200
`sqrt81+sqrt16-3(sqrt9+sqrt49)=`
9+4-3(10) = 9 + 4 - 30 = 13 - 30 = -17 (must have negative sign)
200
6+64=70
200
If the rock fell for 576 feet, how long did it fall?
`d=16t^2`
`t^2=36, so t = 6 seconds`
200
No Calculator: What is
`3^4=`
3*3*3*3=81
300
No Calculator: What is the
`sqrt(121) - sqrt(144)`
-1
300
`sqrt100-sqrt81-sqrt64-sqrt1=`
10 - 9 -8 - 1 =
1 - 8 - 1
- 7 - 1 = -8
300
`100-50div2-10*2=`
100-25-20=55
300
How far did a rock that fell for 4 seconds fall? using :
`d=9t^2`
d =
`9*16=144`
300
What is
`8x+4=8`
8x=4, so x=0.5 or
`1/2`
400
No Calculator: Simplify, what is the
`sqrt(64/16)`
8/4 = 2
400
`f(x)=4x+5; f(9)=?`
4(9) + 5 = 36 + 5 = 41
400
`3^3div3*1-100=`
9-100 = -91
400
How long did a rock fell if it fell for 729 feet. Using:
`d=9t^2`
`
`
`t^2=81; SO , t=9 seconds`
400
What is the sum of -56 + 18?
- 56 + 18, subtract them and keep the sign of 56, so = -38
500
No Calculator: What is
`sqrt(100)+sqrt(16)-sqrt(400)=`
10 + 4 - 20 = -6
500
f(2) - f(9) =
when
`f(x)=x^2-11`
`2^2-11 = -7`
`9^2-11= 81 - 11 = 70`
`-7-70=-77`
500
`15div5*2+3(10-12div4)=`
