Question 8 Multiple Choice Worth 1 points)

Mathematics
1 answer:
satela [25.4K]3 years ago
7 0

Answer:

cos 0=90 degrees

Step-by-step explanation:

If sin of 90 is 1 then cos 90 is 0. Since sin and cos are like complementary angles they angles add up to 90 degrees.

\sin(90)  =  \cos(0)

and since sin 90 equal 1 cos of 0 equal 1.

What if we switch angles

Well they are still equal

\sin(0)  =  \cos(90)

But this time sin of 0 is 0 and cos 90 is 0.

*26 POINTS* pls help
Doss [256]

Answer:

If you want to draw a perpendicular line from a point on a line, you would measure a 90 degree angle from that point and then draw the line outward.

Explanation

On the other hand, if you wanted to draw a perpendicular line connecting a line and a point off of the line, you would have to connect the point to the location on the line that forms a 90 degree angle.

Both methods involve making a 90 degree angle between two lines. Can you think of any other similarities?

If you roll a dice 100 times how many times would you expect to roll a product that is a multiple of 5
Luden [163]

If you're rolling a single cube, then ...

-- There are 6 possible out comes.
-- One of them (5) is a multiple of 5 .
-- The probability of rolling it is (1/6) = <em>16-2/3 %</em> .

If everything is acting perfectly random, then ion 100 rolls,
you'd expect to succeed 16 or 17 times.


If you're rolling a pair of cubes, then ...

-- There are (6 x 6) = 36 possible outcomes.
-- There are seven ways to get a multiple of 5.
(1+4),  (4+1),  (2+3),  (3+2),  (4+6),  (6+4),  (5+5)
-- The probability of rolling one of those is
                                                             (7/36) = <em>19-4/9 %</em> .

If everything is acting perfectly random, then in 100 rolls,
you'd expect to succeed 19 or 20 times.

If six times a number is decreased by fourteen, the result is 124. What is the number
denis23 [38]

Answer:

\large\boxed{23}

Step-by-step explanation:

Six times a number is decreased by fourteen, the result is 124.

Write an equation that represents this

(6 * x) - 14 = 124

Multiply 6 by x to remove the parenthesis

6x - 14 = 124

Add 14 to both sides of the equation

6x = 138

Divide both sides of the equation by 6

x = 23

The unknown number is \large\boxed{23}

Hope this helps :)

The financial statements of the Tyler Company report net sales of $300,000 and accounts receivable of $50,000 and $10,000 at the
iragen [17]

Answer:

the accounts receivable turnover for the Tyler Company is 10

Step-by-step explanation:

The company report :

net sales = $300,000

account receivable  = $50,000 and $10,000

to find the accounts receivable turnover, use the following formula:

accounts receivable turnover = net sales : average account receivable

First, we need to calculate the average account receivable of  the company

average accounts receivable = ($50,000+$10,000) : 2

                                              = $60,000 : 2

                                              = $30,000

Then, substitute net sales into the formula

accounts receivable turnover = $300,000 : $30,000

                                              = 10
