Answer:  a.    320 books

Step-by-step explanation:

Given : The total number of books  were placed on the discount shelf for 70% off the regular price = 960

The fraction of books sold = \dfrac{2}{3}

Then, the number of books sold = \dfrac{2}{3}\times960=640

Now, the number of books remain on the discount shelf = 960-640=320

Hence, the number of books remain on the discount shelf =320

mash [69]

Answer:

The break- even point is attained when n=75

Step-by-step explanation:

The break-even point is defined as the point where revenue is equal to cost.

We take the equation for revenue r=15n, and set it equal to the equation c=9n+450

15n=9n+450

Subtract 9n from both sides:

6n=450

Divide both sides by 6.

6n/6=450/6

n=75

The break- even point is attained when n=75....

If the measure of arc AD is 65 degrees and the measure of arc BC is 45 degrees, what is the measure of angle BEC?
krek1111 [17]

Answer:

\angle BEC=55 \textdegree)

Step-by-step explanation:

From the question we are told that:

Arc AD =65 \textdegree

Arc BC =45 \textdegree

Given The angle of intersecting chords theorem

Generally the equation for angle BEC is mathematically given by

 \angle BEC=\frac{1}{2} (\angle of arc AD+\angle of arc BC)

 \angle BEC=\frac{1}{2} (65 \textdegree+45 \textdegree)

 \angle BEC=55 \textdegree)

URGENT PLEASE HELP ME<br> what side is the adjacent and opposite
trapecia [35]

Answer: Line DE is the adjacent while line EF is the opposite.

Step-by-step explanation: This is a right angled triangle and the reference angle has been marked at point D. If you drew a line from that angle it would touch the triangle at line line EF. It’s facing the reference angle and that’s why it’s called the “opposite.”

The line that lies between the reference angle and the right angle is called the adjacent and that’s line DE in this triangle. The hypotenuse has already been identified for you, and that’s the line that’s opposite the right angle (it’s always the longest side).

**Please note that the opposite and adjacent ALWAYS depends on where the reference angle is positioned.

30 percent of what number is 12
Gnesinka [82]
Another way of saying this is "12 is 30% of what number." Knowing that "of" is code word for "multiply" and 30%= 0.30, we can set up this equation, where x = the unknown number:
12=0.30x

To solve for x, all we have to do is divide both sides by 0.30, like so!
12=0.30x  \\  \frac{12}{0.30} = \frac{0.30}{0.30}x \\ x=40

The answer is x = 40, or 30 percent of 40 is 12.

Hope this helps!
