This is adding two vectors, one magnitude 300 direction east, and one magnitude 100 direction 30 degrees northeast.

For the resulting sum we can use the Law of Cosines or just add up the components.  Let's try it both ways.

Components first.   In the east direction we have

300 + 100 cos 30° = 300 + 100(√3/2) = 386.60 miles per hour

In the north direction we have

0 + 100 sin 30° = 100 (1/2) =  50 miles per hour

So a total speed of

sqrt{386.6^2 + 50^2} = 389.82 miles per hour

Answer: 389.82

--------

OK let's try the Law of Cosines.   We have sides 300 and 100 and included angle 150°.

c^2 = 300^2 + 100^2 - 2 (300)(100) \cos 150^\circ

c=\sqrt{151961.52422} = 389.82 \quad\checkmark

the barkery you choose costs $1,000 per month to rent. The bakery that you almost rented was 1/4 the cost but was much too small
liubo4ka [24]
Well the easiest way to figure out this question is to just divide it by 4, like quarters, so 1000 divided by 4 is 250. so the other bakery was only 250. hope this helped

astra-53 [7]

Answer:

1/2

Step-by-step explanation:

Given that:

3/4 of pizza has pepperoni

2/3 of the pizza with pepperoni has green pepper ;

The fraction of the whole pizza that has both pepperoni and green pepper ;

Fraction with pepperoni = 3/4

Fraction of whole with green pepper and pepperoni : 2/3 of 3/4 = 2/3 * 3/4 = (2*3) / (3*4) = 6/12 = 1/2
