Answer:

5 students got both a pencil and a notebook

Step-by-step explanation:

What I did was to know which multiplication table I knew better and not do that one. So, I already have 9, 18, 27, 36, 45, 54, 63, 72, 81, 90, 99

Then I matched it with the 6's.

6, 12, 18, 24, 30, 36, 42, 48, 54, 60, 66, 72, 78, 84, 90, 96, 102

(This may not be the official method but I found this method the easiest)

So therefore your answer would be 5 students.

The area of a rectangular garden in square feet can be represented by z² - 10z +21. The length is z - 7 feet. You have been hired to fertilize the

garden. Recall that the area of the garden is z² - 10z +21. If z = 20 and the fertilizer costs $0.27 per square foot, how much it cost to fertilize

the garden?

Answer:

$ 59.67

Step-by-step explanation:

The area of a rectangular garden in square feet can be represented by z² - 10z +21 square feet

If z = 20

Therefore:

The area of the rectangular garden is:

20² - 10 × 20 + 21

400 - 200 + 21

= 221 square feet

The fertilizer costs $0.27 per square foot, how much it cost to fertilize

the garden?

The cost of fertilize the garden is calculated as:

1 square feet = $0.27

221 square feet = x

Cross Multiply

221 square feet × $0.27

=$ 59.67

Find the slope of the line that passes through points (3,5) and (8,5)

Katyanochek1 [597]

Answer: m = 0

Step-by-step explanation: To solve this problem, we don't even have to use our slope formula. It's important to understand that when we have the same y coordinate in our first ordered pair and our second ordered pair, this means that the line will be flat or horizontal.

When a line is horizontal, it means the line has a slope of zero.

We use the variable m to represent slope.

So here, we can say that m = 0.
