Find BD

Remember soh-cah-toa?

opposite/adjacent

tan30=400/x

xtan30=400

x = 400/tan30

Find BC

Still toa. . . still toa

90 + 60 = 150

180-150 = 30

BAC = 30

tan30=x/400

400tan30=x

BD-BC=CD

If you followed my steps, your answer should come to you.

If you didn't and are a lazy pr*ck who relies on others to do their semester exam problems for them, the answer is A.  Or 461.

20% of the seventh-grade students have math class in the morning. 16 2/3 % of those students also have science class in the morn
Lena [83]
Let x be the number of seventh grade students.

The 20% of the seventh grade students have math class in the morning means mathematically is 20/100.

The 16 2/23% of those students also have science class in the morning means:

16 2/3 & 20/100 = also have class in the morning
83 1/3 * 20/100 = math in the morning but not in science in the morning

30 students have math in the morning but not science in the morning

83 1/3% * 20/100% * x = 30
250/3 * 20/100x = 30
x = 180

There are 180 seventh graders.

-3x+2y=6 Find the intercepts. Show your work.
Arte-miy333 [17]

Answer:

The x-intercept is (-2,0)

The y-intercept is (0,3)

Step-by-step explanation:

An x-intercept is the point when the graph crosses the x-axis. In other words, the y-coordinate of the x-intercept is 0 (since it lays on the x-axis). In other words, to solve for the x-intercept(s), plug in 0 for y and solve for x:

-3x+2y=6\\-3x+2(0)=6\\-3x=6\\x=-2

So, the x-intercept is (-2,0).

Likewise, the y-intercept is the point when the graph crosses the y-axis. Because it's on the y-axis, the x-coordinate value would be 0. Thus, to find the y-intercept, plug in 0 for x and solve for y:

-3x+2y=6\\-3(0)+2y=6\\2y=6\\y=3

Thus, the y-intercept is (0,3).

2 cards are drawn from a standard deck without replacement. What is the probability that at least one of the cards drawn is an a
olya-2409 [2.1K]

Answer:

<h2>The answer is 0.1493.</h2>

Step-by-step explanation:

In a standard deck there are 52 cards in total and there are 4 aces.

Two cards can be drawn from the 52 cards in ^{52}C_2 = \frac{52!}{50!\times2!} = 51\times26 ways.

There are (52 - 4) = 48 cards rather than the aces.

From these 48 cards 2 cards can be drawn in ^{48}C_2 = \frac{48!}{46!\times2!} = 47\times24 ways.

The probability of choosing 2 cards without aces is \frac{47\times24}{51\times26} = \frac{188}{221}.

The probability of getting at least one of the cards will be an ace is 1 - \frac{188}{221} = \frac{33}{221} = 0.1493.
