From the observation deck of a skyscraper, Meena measures a 45 angle of
depression to a ship in the harbor below. If the observation deck is 862 feet high,
what is the horizontal distance from the base of the skyscraper out to the ship?
Round your answer to the nearest tenth of a foot if necessary.

Answer:

If you want to know the process on how to graph and shade, start by graphing the inequalities. Assume that the inequality signs are just =, so the equation is y=mx+b. Let's use 1) as an example. When the sign is < or >, it's a dotted line. If the sign is ≥ or ≤, it's a solid line. Once you're done graphing the inequalities, choose a random coordinate on the graph. Let's use (0,0). Now, plug in the x- and y-value into the equations. 0<-6(0)+3 and 0≤0-2. Simplify it to get 0<3 and 0≤-2. Because the inequality is true for y<-6x+3, you would shade the side of the graph that includes (0,0). Because the inequality isn't true for y≤-x-2, you would shade the side of the graph that doesn't include (0,0). The shaded parts of both inequalities should overlap somewhere and that's the area you need to officially shade.

I was looking for 4(x-4),   but 4(x-2)(x+2) also works

Answer:

4(x - 2)(x + 2)  (Answer B)

Step-by-step explanation:

4x^2 - 16 is the difference of two squares, a case in which there is a simple formula to remember:  a^2 - b^2 = (a - b)(a + b)

4x^2 - 16 = (2x - 4)(2x + 4)

This can be further simplified:  2(x - 2)(2)(x + 2) = 4(x - 2)(x + 2)  (Answer B)

No, they are the same triangles

Step-by-step explanation:

They both have a side length of 3 and 5 and an angle that measures 60 degrees. The triangles are just flipped in different directions.

If they were to draw an additional triangle that would make it seem different, they could expand the angle and make it obtuse to get a triangle with 1 wide corner.

Answer:

100

Step-by-step explanation:

700/7%

The missing sides of the right-angle triangle x and y will be 73.36 units and 46.16 units.

It's a form of a triangle with one 90-degree angle that follows Pythagoras' theorem and can be solved using the trigonometry function. The Pythagoras theorem states that the sum of two squares equals the squared of the longest side.

Then the value of x will be

cos 39° = 57 / x

  0.777 = 57 / x

         x = 73.36

Then the value of y will be

tan 39° = y / 57

0.8097 = y / 57

         y = 46.16

Answer:

Lin's father pay for the meal is $18.19

Step-by-step explanation:

Given:

Lin’s father is paying for a $20 meal.

He has a 15%-off coupon for the meal.

After the discount, a 7% sales tax is applied.

Now, to get the amount Lin's father pay for meal.

So, we deduct the 15% discount first:

$20 - 15% of $20.

Then, adding 7% sales tax:

$17 + 7% of $17

Therefore, Lin's father pay for the meal is $18.19.

IQR- 18

Step-by-step explanation:

I don't know the explanation

The IQR of the data is 18 and MAD is 8.

The interquartile range in descriptive statistics reveals the spread of your distribution's middle half. Any distribution that is sorted from low to high is divided into four equal portions using quartiles. The second and third quartiles, or the centre half of your data set, are contained in the interquartile range (IQR).

We have the data

25, 31, 27, 33, 41, 39, 48, 46, 52

Arranging the data

25, 27, 31, 33, 39, 41, 46, 48, 52

So, Q1 = (n+1)/4

Q1 = (9+1)/4

Q1 = 2.5

Q1 = 29

and, Q3 = 3/4(n+1)

Q3 = 3 (2.5)

Q3 = 47

So, IQR = Q3 - Q1 = 47-29 = 18

and, MAD = ( 13 + 11 + 7 + 5 + 1 + 3 + 8 + 10 + 14)/9

MAD = 8

Each person will get [tex]\frac{1}{8}[/tex] of the whole package of pencils.

Step-by-step explanation:

Since we know that 3/8 of the package was divided among 3 people we just have to divide 3/8 by 3 in order to find out what fraction of the whole package of pencils each person will receive. And so we get...

   [tex]\frac{3}{8}[/tex] ÷ 3 = [tex]\frac{1}{8}[/tex]

Therefore, each person will get 1/8 of the whole package of pencils.

Step-by-step explanation:

30 miles a hour divide by 60 so your going half a mile a minute

Your speed in feet per minute is 2640 ft/min.

A unit rate means a rate for one of something.

Given that, Your rate of speed is 30 miles for every 1 hour

We know, 1 mile = 5280 feet

Therefore, 30 miles = 30x5280 = 158400 feet

That means, you are travelling 158400 feet for every hour

In an hour, there are 60 minutes,

Therefore, you are travelling 158400 feet in every 60 minutes.

In 60 minutes = 158400 feet

In 1 minute = 158400/60 = 2640 feet

That means you are travelling 2640 feet in every 1 minute.

Hence, your speed in feet per minute is 2640 ft/min.

Find total marbles:

2 + 3 + 5 = 10

A. There are 2 red, so probability of picking red would be 2 out of 10 which would be 2/5. So A is false.

B. 3 blue + 5 green = 8 marbles. Probability of picking blue or green would be 8 out of 10 which would be 4/5 so B is false.

C. Picking green would be 5 out of 10 which would be 1/2 so c is true.

D. Picking not red would be picking green or blue which is the same as B. Which is 4/5 so D. Is true.

E. Since half the marbles are green and half the marbles are not green this one is also true.
