The answer is C) 16 blocks.

We will use the distance formula for this problem:

d=\sqrt{(x_2-x_1)^2+(y_2-y_1)^2}

From your house to the internet cafe:

d=\sqrt{(8-6)^2+(12-2)^2}=\sqrt{2^2+10^2}=\sqrt{4+100}
\\
\\=\sqrt{104}=10.2

From the internet cafe to your friend's house:
d=\sqrt{(8-4)^2+(12-8)^2}=\sqrt{4^2+4^2}=\sqrt{16+16}=\sqrt{32}=5.7

Together, we have 10.2+5.7=15.9, which rounds to 16 blocks.

Simplify the expression. (3.14×107)×(1.3×10−3)÷0.2<br> Scientific notation PLS!
marusya05 [52]

3.14 \times 107 = 335.98
(335.98) \times (1.3 \times 10 - 3) \div 0.2
1.3 \times 10 = 13 - 3 = 10
(335.98) \times (10) \div 0.2
335.98 \times 10 = 3359.8
3359.8  \div 0.2 = 16799
1.6799 \times  {10}^{4}
