Please help :d in on a time limit before it becomes late!!

Answer:

volume of toy = volume of water after placing toy in it - volume of water before placing toy in it

volume of toy = 23mL - 10mL

volume of toy = 13mL

The increase in the volume of water when the toy is submerged in it is equal to the volume of the toy.

SO VOLUME OF WATER IS 13mL

Select all the situations that describe a probability of 1/6 of drawing a red marble out the bag.

konstantin123 [22]

The correct answer is E (6 red, 4 yellow, 8 green, 6 blue, 12 white).

E) 6 + 4 + 8 + 6 + 12 = 36 (total marble count)
6 red/36 total marbles
simplify to find the probability ⬇️
(6/6=1; 36/6=6) = 1/6 chance of picking red

Please help me!!!!! How do you get 67.3 and 112.7 from .9228

antoniya [11.8K]

Answer and Step-by-step explanation:

You are correct in that we need to use the Law of Sines: $\frac{c}{sinC} =\frac{b}{sinB}=\frac{a}{sinA}$ .

Here, when we use the Law of Sines, we have: $\frac{28}{sin(63)}=\frac{29}{sinB}$ .

Cross multiply:

(sinB) * 28 = (sin63) * 29

28sinB ≈ 25.839

sinB ≈ 0.9228

Now, in order to solve for B, we need to use inverse sin ( $sin^{-1}$ ):

$sin^{-1}(sinB)=sin^{-1}(0.9228)$

The sines on the left cancel out, and we're left with:

B ≈ 67.3 degrees

Now, one thing to keep in mind when doing Law of Sines is that there is potentially more than one answer possible for the degree measure. The other degree measure can be found by subtracting this one from 180:

180 - 67.3 = 112.7 degrees.

Hope this helps!
