2. Find the measure of angle L.
BabaBlast [244]

Answer:

∠ L ≈ 21.6°

Step-by-step explanation:

Using the Sine rule in the triangle

\frac{MN}{sinL} = \frac{LM}{sinN} , that is

\frac{34}{sinL} = \frac{42}{sin27} ( cross- multiply )

42 × sinL = 34 × sin27° ( divide both sides by 42 )

sinL = \frac{34sin27}{42} , then

∠ L = sin^{-1} ( \frac{34sin27}{42} ) ≈ 21.6° ( to the nearest tenth )

Jen was making cake pops for the bake sale. After 3 hours, she had completed half of the work. She called Maryna for help and to
Inga [223]

Answer:

0.6 hours

Step-by-step explanation:

Let's say J is Jen's speed (cake pops per hour), and let's say M is Maryna's speed (cake pops per hour).

Let's say there are 12 cake pops total that need to be made.  Jen made half of the cake pops in 3 hours, so she made 6 cake pops in 3 hours.  So her speed is 2 cake pops per hour.

Then, Jen and Maryna made the other half of the cake pops in 1/2 hour.  Therefore, their combined speed is:

J + M = 6 cake pops / (1/2 hr)

J + M = 12

2 + M = 12

M = 10

So Maryna can make 10 cake pops per hour.

If Maryna was working alone, the amount of time it would take her to make 6 cake pops is:

6 cake pops / (10 cake pops per hour) = 0.6 hours

It would take 0.6 hours, or 36 minutes.
