The answer is n=(a-b)-1 because when you subtract a-b, you get almost the number of pages, but as you are counting the page b which has is not torn out, you must subtract 1 to get the correct answer if you plugged in a variable

What is the slope of the line described by the equation below?
postnew [5]

Answer: 4

Step-by-step explanation: First convert the equation to y = mx + b form.

Start by subtract 4x from both sides to get -y = -4x + 3.

From here, divide both sides by -1 to get y = 4x - 3.

Now in y = mx + b form, the slope is the multiplier, or the <em>m</em>.

So here, 4 is the slope.

The courtyard behind Jennie’s house is shaped like a trapezoid the bases measure 8 meters and 11 meters the height of the trapez
almond37 [142]

Answer:

104.5 meters square

Step-by-step explanation:

The area of a trapezoid is found using the formula A = 1/2 (a + b)h. Substitute a = 8, b = 11 and h = 12.

The area is A = 1/2(8+11)*12.

A = 1/2 (19)*12 = 104.5

The amount of the tip each waiter receives after a wedding is inversely proportional to the number of waiters serving the event.
iogann1982 [59]

Answer:

The relationship between n and t is n*t=1200 (option d)

Step-by-step explanation:

Two quantities are inversely proportional if when multiplying (or dividing) one of them by a number, the other is divided (or multiplied) by the same number. That is, two magnitudes are inversely proportional if when one increases, the other decreases in the same proportion.

Given two variables, x and y, with an inversely proportional relationship, the product of both is always constant and equal to the coefficient of proportionality:

x*y=k

where k is the coefficient of proportionality.

This means that knowing the value of the proportionality coefficient and the value of a variable, the value of the other variable can be known through the quotient between the proportionality coefficient and the value of the known variable:

y=\frac{k}{x}

The amount of the tip "t" each waiter receives after a wedding is inversely proportional to the number of waiters "n" serving the event. The total amount for tips at a wedding was $1,200.Taking into account the aforementioned definition of inversely proportional quantities, this can be expressed by:

n*t=1200

<u><em>The relationship between n and t is n*t=1200 (option d)</em></u>

The equinoxGroup of answer choicesis when the subsolar point is at one of the tropics.is the longest day of the year at any give
Maurinko [17]

Answer:

c. has 12 hours of day and 12 hours of night for all locations

Step-by-step explanation:

The equinox is the time of the year marked by a nearly equal length of day and night. This word has a Latin root meaning which stands for equality, hence the word 'equinox'. It usually falls on March 21, and September 23 of every year. On these days the sun is above the equator.

The equinox which occurs around September happens in the Northern Hemisphere and is also known as the Fall or Autumnal equinox. Whereas, the equinox which occurs at the Southern Hemisphere is also known as the Spring or Vernal equinox. During an equinox, the tilt of the earth is perpendicular to the sun.
