Answer:
4 blocks shorter.
Step-by-step explanation:
Noam walks home from school by walking 8 blocks north and then 6 blocks east.
If Noam walks 8 blocks from School at A towards north to the point B and then from B towards east by 6 blocks to reach home at C, then Δ ABC will form a right triangle whose sides with 90° are AB = 8 blocks and BC = 6 blocks and AC is the hypotenuse which is given by
AC² = AB² + BC² = 8² + 6² = 100
⇒ AC = 10 blocks.
So, total distance that Noam travels is (8 + 6) = 14 blocks.
And if he walks along AC, then the distance will be 10 blocks which is (14 - 10 ) = 4 blocks shorter than his actual path. (Answer)
The whole bill is $31.99 that is 100%. You can use mental math to determine exatcly 15% from $31.99:
1. 15%=10%+5%
2. To find 10% from $31.99 you should simply divide $31.99 by ten. Thus, 10% from $31.99 is $3.199.
3. 5% is half of 10%, then 5% from $31.99 is $3.199:2=$1.5995.
4. 15% from $31.99 is $3.199+$1.5995=$4.7985≈$4.80.

Answer:
4 in
Step-by-step explanation:
volume = 64 in³
side = cubic root of 64 in³
side = 4 in
Check: If a cube has side 4 in, then its volume is 4 in × 4 in × 4 in = 64 in³.
This shows that the answer 4 in is correct.
