Write 28 x 32 in associative property

Answers

Answer:

32 * 28

Step-by-step explanation:

Just flip the positions of the two and you have your answer

the associative property states that (in this case) changing the order of the numbers in the equation does not change the product. for example, "a" times "b" is equal to "b" times "a". this means 28 x 32 is equal to 32 x 28. so, 28 x 32 using the associative property is 32 x 28.

Cheryl owes more money to the bank. |-3| = 3 and |-2.75| = 2.75. As you can see Cheryl's amount of money is greater when you find the absolute value of it, but since it was negative it means that she actually owes more money.

Question 1
A truck driver drove 48 miles in 45 minutes. At this rate, how many miles can the truck driver drive in one hour?



__ miles in one hour
pls no links ty

Answers

The truck driver can drive 64 miles in one hour.

Distance covered by the truck driver in 45 minutes = 48 miles

Distance covered by the truck driver in 1 minute = [tex]\frac{48}{45}[/tex]

                                                                                 = 1.066 miles

Distance covered by the truck driver in 1 hour i.e. 60 minutes = 60 × 1.066

                                                                                                      = 63.96

                                                                                                      ≈ 64 miles

Therefore, the distance covered by the truck driver in 1 hour is 64 miles.
