Answer: 45

Step-by-step explanation: To divide this start with finding how many times 585 goes into 13 which is 0. I put a picture for you to look at.

Think about the function f(x) = 3 - 2x. What does the notation f(0) mean?

dlinn [17]

In order to find this you have to replace any x with zero therefore we will have
3 - (2*0) => 3-0 = 3
so the answer is 3

Write two fractions with different denominators whose LCD is 36.

mestny [16]

Two whole numbers whose least common denominator is 36 could be many different pairs: 1 and 36, 2 and 36, 3 and 36, 4 and 36, 4 and 18, 4 and 9, 6 and 36, 9 and 36, 9 and 12, 12 and 36, 12 and 18, 18 and 36, and lastly 36 and 36.

If you want fractions in simplest form, with different denominators, and with an LCD of 36, I would go with 4/5 and 9/13.

I think the reason these work is because 5, 13, and 36 are all pairwise relatively prime (meaning the LCD of any two of them is their product), and because the LCD of 4 and 9 is 36, like I said earlier.

What is 5π/6 radians converted to degrees? If necessary, round your answer to the nearest degree.

klemol [59]

Answer:

300 degrees

Step-by-step explanation:

we know that $\pi = 360 degrees$ $\pi = 360 \ degrees$

we have to find value of $5\pi /6$

for that we have to multiply 5/6 to $\pi$ and 360 degrees

$\pi = 360 \ degrees\\5\pi /6 = 5/6 *360 = 300$

Thus, $5\pi /6$ = 300 degrees.

Margot is studying the yield of bushels of wheat in comparison to the amount of rainfall, in inches, that occurs. She finds the

crimeas [40]

Let y be the yield of bushels of wheat in comparison to the amount of rainfall
Let x be the amount of rainfall that occurs (in inches)

If the linear regression equation is y = 47.3 + 0.78x, then per inch of rainfall will yield an addition 0.78 bushels (plugging into x the additional inches of rainfall).

Therefore, on the first inch of rainfall, y = 48.08.
On the second inch of rainfall, y = 48.86.

And so on.

The drama club is selling short-sleeved shirts for $5 each, and long-sleeved shirts for $10 each. They hope to sell all of the s

liraira [26]

Answer:

The drama club ordered 150 short-sleeved shirts and 100 long-sleeved shirts

Step-by-step explanation:

1. Let's review all the information provided for answering the questions properly:

5x + 10y = 1,750

1/3x + 1/2y = 100

x = number of short-sleeved shirts ordered

y = number of long-sleeved shirts ordered

Resolving the 1st equation:

5x + 10y = 1,750

5x = 1,750 - 10y

x = 350 - 2y (Dividing by 5 at both sides)

Resolving the 2nd equation:

1/3x + 1/2y = 100

1/3 (350 - 2y) + 1/2y = 100

350/3 -2y/3 + 1/2y = 100

700 - 4y + 3y = 600 (Lowest common denominator = 6)

-y = 600 - 700 (Subtracting 700 at both sides)

y = 100 (Dividing by - 1)

Finding the value of x in the 1st equation:

5x + 10 (100) = 1,750

5x + 1,000 = 1,750

5x = 1,750 - 1,000 (Subtracting 1,000 at both sides)

5x = 750

x = 150 (Dividing by 5)

2. Proving that x = 150 and y = 100 are correct

1/3x + 1/2y = 100

1/3 * 150 + 1/2 * 100 = 100

150/3 + 100/2 = 100

50 + 50 = 100

100 = 100

We proved that x = 150 and y = 100 are correct
