Answer:

h = 20

Step-by-step explanation:

So the first thing we need to do here is distribute our one third so we can then deal with the 18 on the other side of the equation.

So lets distribute!

1/3(3h-6) = h - 2

This is because 1/3 x 3 = 1 and 1/3 x 6 = 2

We could also re-write both of these above to get

3/3 = 1 and 6/3 = 2

So now we have

18 = h - 2

All that is left now is to add two to both sides!

Which leaves h = 20

In AABC, MZA = 16°, mZB = 49°, and a = 4. Find c to the nearest tenth.

zhannawk [14.2K]

Answer:

Step-by-step explanation:

The sum of angles in a triangle is 180°, so angle C is ...

C = 180° -A -B

C = 180° -16° -49° = 115°

The measure of side c can be found from the Law of Sines:

c/sin(C) = a/sin(A)

c = a·sin(C)/sin(A) = 4·sin(115°)/sin(16°)

c ≈ 13.2

There are three different cubes such that the first cube is 64 times the volume of the second, and the volume of the second cube

tankabanditka [31]

Answer:

4/3

Step-by-step explanation:

If the ratio between the volumes of the first and the second cube is 64, the ratio between the sides is the cubic root of the ratio between the volumes, so:

$V1 / V2 = 64$

$s1 / s2 = \sqrt[3]{64} = 4$

Doing the same for the second and third cubes, we have:

$V2 / V3 = 1/27$

$s2/ s3 = \sqrt[3]{1/27} = 1/3$

So the ratio of the first cube side and the third cube side is:

$s1 / s3 = (s1/s2) * (s2/s3) = 4 * (1/3) = 4/3$
