Answer:

A. $0.99p

B. $0.99(8) = $7.92

Step-by-step explanation:

To show that you multiply the unit price by the amount, we can use the variable p. Now, this equation shows that you multiply the price per one pound by the amount of pounds.

If you want to find the cost of 8 pounds, you just put the 8 in place of the p to represent how many pounds. Now, you just need to multiply 0.99 x 8, which equals $7.92.

To form 3 adjacent squares (as in the figure), 10 toothpicks are required. How many toothpicks are required to form 100 adjacent
Sonja [21]
<span>Let's say in general you want "n" adjacent squares. Each one needs a top, so that's n toothpicks. Each one needs a bottom, so that's another n toothpicks, and we're up to 2n total. You need one on the far left, and one on the far right, which brings us up to 2n + 2 toothpicks. Now we need to worry about the middle ones. But notice that you don't need n toothpicks for the interior because adjacent squares share. It turns out that you only need n-1. That brings us up to a grand total of 3n + 1 toothpicks, which would be 301 for n = 100.

Answer:

Calculating (5 x 2) violates the order of operations

Step-by-step explanation:

According to the order of operations, multiplies all have equal priority. Therefore, they must be evaluated left to right, not right to left. Evaluating (5 x 2) first is incorrect, and instead (9 x 5) should be calculated first.
