Write a compound inequality that represents the situation. On a road in the city of Rochester, the maximum speed is 50 miles per hour, and the minimum speed is 20 miles per hour.A. 20 ≥ x ≥ 50

B. 20 < x < 50

C. 20 > x > 50

D. 20 ≤ x ≤ 50

Answers

Answer:

D) 20 ≤ x ≤ 50.

Step-by-step explanation:

Given : , the maximum speed is 50 miles per hour, and the minimum speed is 20 miles per hour.

To find: Write a compound inequality that represents the situation.

Solution : We have given that

Maximum speed  = 50 miles per hour.

Minimum speed  = 20 miles per hour.

Let x represent the speed .

According to question

maximum speed  is 50 or less than 50.

Then we will use less than equal to sing

x ≤ 50

For Minimum speed is 20 or greater than 20 .

x ≥ 20

On combining both statement,

20 ≤ x ≤ 50

Therefore, D) 20 ≤ x ≤ 50.

Write the following into rational numbers a over b (a and b are integers)a. 15.89898989 b. 0.101010

Answers

Answer: a.) 15 and 89/99

b.) 10/99

Step-by-step explanation:

a.) 15.898989...

Let x = 0.898989...

100*x = 89.8989...

100x - x = 89.898989... - 0.898989...

99x = 89

x = 89/99

So 15.898989.... = 15 and 89/99

b.) 0.101010

Y= 0.101010

100y = 10.101010...

100y - y = 10

99y = 10

y = 10/99
