First you add 11 to both sides
6a-11=13
+11 +11

So you get:

6a=24
Next divide both sides by 6
6a=24
6 6

A helicopter rose vertically 300m and then flew west 400m. how far was the helicopter from it starting point?

Answers

$a^(2) + b^(2) = c^(2) 300 ^(2) + 400 ^(2) = c^(2) c^(2) =250,000 √(250,000)=500m$

The helicopter rose vertically, and then flew horizontally, so it's final displacement (distance from where it is now to where it started) is in the shape of a triangle.

The displacement is the hypotenuse of this triangle, with sides 300m and 400m.

We can work out this distance using Pythagorus' theorem, because we know that;

$a^(2) = b^(2) + c^(2)$

Where $a$ is the hypotenuse, and $b$ and $c$ are the two other sides. So;

$a^(2) = b^(2) + c^(2) \n \n a^(2) = 300^(2) + 400^(2) \n \n a^(2) = 90000 + 160000 \n \n a = √(250000) \n \n a = \boxed{500m}$

2/3 of the product of 3/8 and 16

Answers

Well in order to find 2/3 of the product of those two numbers
first we gotta figure out their product:)
lets do that first
3 3 16
---- x 16 or lets write it like this ---- x -----
8 8 1

and when you multiply fractions you just multiply across literally!!
ill show you

3 16 = 3 x 16 = 48
--- x -----
8 1 = 8 x 1 = 8

so now we have our new fraction!
48
-----
8
now we also know that this fraction also equals 6
so if we are trying to figure out 2/3s of 6 we would have to multiply them
but first lets try to change 2/3s to a decimal or in this case 0.6666666667
soooo now we multiply that by 6
0.6666666667 x 6 = 4
so that means that 2/3 of 6 is 4
hey! we have our answer:)
answer? 4
also dont forget to
