Rachel rides her bicycle due east at 12 kilometers per hour. Amos rides his

Dominik [7]

Answer:

40 km away.

Step-by-step explanation:

a^2 + b^2 = c^2

In this case, a = 16 * 2 = 32 km, since he travels 16 km per hour for 2 hours.

b = 12 * 2 = 24 km, since she travels 12 km per hour for 2 hours.

32^2 + 24^2 = c^2

1,024 + 576 = c^2

1600 = c^2

c^2 = 1600

c = plus or minus 40

Since distance cannot be negative, they will be 40 km away.

Hope this helps!

How do i Simplify, using order of operations: the following problem?

spayn [35]

Hello!

Explanation: This question's it's about the order of operations. It stands parenthesis, exponents, multiply, divide, add, and subtract. It can also go left too right.

First, you had to do is calculate parenthesis first.

$3*2+(4+9/3)$

$9/3=3$

$4+3=7$

$3*2+7$

Next, multiply from left too right.

$3*2=6$

$6+7=13$

Then you add left too right.

$13+6$

$13+6=19$

Final answer: → $\boxed{=19}$

Hope this helps!

Thank you!

Have a great day!
