As we know, this deals with percentages so 10% of 50 would be 5, because 5 x 10 is 50 we can divide them into 5 equal groups. and the answer is A ; it rounds down to 50 since when you do 9 percent of 578 it goes into 52.02 groups of 9. and we round down

A French restaurant used 92,870 ounces of cream last year. This year, due to a menu update, it used 100% less. How much cream di
ValentinkaMS [17]

Answer:

<u>The French restaurant did not use cream this year, due to a menu update.</u>

Step-by-step explanation:

1. Let's review the information given to us to answer the question correctly:

Amount of cream used by a French restaurant last year = 92.870 ounces

Amount of cream used by the French restaurant this year = 100% less

2.  How much cream did the restaurant use this year?

The answer is zero and we calculated it this way:

92,870 - 100% (92,870) = 92,870 - 92,870 * 1 = 92,870 - 92,870 = 0

<u>The French restaurant did not use cream this year, due to a menu update.</u>

This table represents a quadratic function with a vertex at (1, 1). What is the
erastova [34]

The average rate of change on the interval (5, 6) is 9. So the correct option is D.

<h3>How to find the average rate of change on the interval?</h3>

Here we want to find the average rate of change of f(x), the function on the table, on the interval (5, 6).

This is just:

r = \frac{f(6) - f(5)}{6 - 5}

f(x) = a*x^2 + b*x + c

I we look at the table we see that:

f(1) = 1 = a + b + c

f(2) =2 =  4a + 2b + c

f(3) = 5 = 9a + 3b + c

This is a system of equations.

If we subtract the second and first functions, we get:

2 - 1 = (4a + 2b +c) - (a + b + c)\\1 = 3a + b = a + b + c

From that we take two relations:

1 - 3a = b\\2a = c

Now we can replace these two in the last equations so we get:

5 = 9a + 3b + c\\\\5 = 9a + 3*(1 - 3a) + 2a\\\\5 = 9a + 3 - 9a + 2a\\\\5 = 3 + 2a\\\\5 - 3 = 2a\\\\2 = 2a\\\\a = 1

Now that we know the value of a:

c = 2a = 2*1 = 2\\\\b = 1 - 3a = 1 - 3 = -2

The quadratic equation is:

f(x) = x^2 - 2x + 2

Evaluating this in x = 6 we get:

f(6) = 6^2  - 2*6 + 2 = 26

And from the table we know that f(5) = 17, then the average rate of change is:

r = \frac{f(6) - f(5)}{6 - 5} = \frac{26-17}{1} = 9

The correct option is D.

Answer two questions please
stepladder [879]

Answer:

<em>3. x = 8</em>

<em>4. lines r and s</em>

Step-by-step explanation:

3.

The angles shown are same side interior angles, so they are supplementary. Their measures add to 180 deg.

5x + 10 + 130 = 180

5x + 140 = 180

5x = 40

x = 8

4.

Lines r and s are cut by a transversal, line l. Angles 3 and 6 are alternate interior angles. Lines r and s are parallel.
