Evan’s family drove to a theme park for vacation. Assume they drove the same speed throughout the trip. The first day, they drove 300 miles in 6 hours. The second day, they drove 250 miles in 5 hours. The third day, they arrived at the park by driving ________ miles in 3 hours.A. 30
B. 125
C.150
D.100

Answers

In the given problem the best hint that is given for getting to the answer is that Evan's family drove at the same speed each day.
Then
On the first day the speed of the car = Distance/time
   = 300/6
   = 50 miles/hour
Then for calculating the distance traveled on the third day = speed * time
   = 50 * 3
   = 150 miles
Then on the third day they arrived at the park by driving 150 miles in 3 hours. So the correct option is option "C".

300÷6 is 50 so they travel 50 miles per hour. that means, in 3 hours they can travel 150 miles so the answer is C

Why the commutative and associative properties don't hold true for subtraction and division

Answers

The commutative and associative properties do not apply to both subtraction and division because once you move around your variables, you will produce different results, whereas in addition and multiplication, any change in position of numbers won't affect the result. The identity properties apply to them because once you add, subtract, multiply, or divide a certain number from any other number, you produce the same result, or, in other words, keep the number's "identity".

Juan purchased 16 lemons and used 5 on the first day of making lemonade. On the second day, he purchased 12 lemons and used 11. Juan wrote this expression to find how many lemons he should have left. (16 – 5) + (12 – 11) Which expression correctly uses the additive inverse and properties of operations to show the same value? (–16 + –12) + (–5 + –11) 16 + (–5 ) – 12 + (–11) 16 + 12 + (11 – 5) (16 + 12) + (–5 + –11)

Answers

Answer: Last Option

$(16 + 12) + (- 5-11)$

Step-by-step explanation:

The associative property states that no matter the order in which you add the number groups, the result will always be the same.

The original expression is as follows:

$(16 - 5) + (12 - 11) = 12$

Now if we apply the associative property we can rewrite the expression as shown:

$(16 + 12) + (- 5 + (- 11))$

Now notice that the result remains the same:

$(16 + 12) + (- 5-11) = 12$

Therefore the correct answer is the last option

Answer:

D : (16 + 12) + (–5 + –11)

Mrs. ciampa had 27 students In her class last year and this year she had 30 students in her math class. What is the percent of change?

Answers

The percent of change in the class of Mrs. Ciampa who has 27 students In her class last year and 30 students this year in her math class is 11.11%.

What is percentage increase ?

Percentage increase is the amount added to the initial value in the percentage part.

Mrs. Ciampa had 27 students In her class last year. This year she had 30 students in her math class.

Thus, the percentage change or increase of the student in her class is,

$p=(30-27)/(27)*100\np=11.11\%$

The percent of change in the class of Mrs. Ciampa who has 27 students In her class last year and 30 students this year in her math class is 11.11%.
