The distance between him and school is 1.59 miles. Of course this distance is linear to make this problem simple. He walks with a speed of 3 miles per hour or 0.00083 mile per second.
To calculate time from distance and speed we use this formula: seconds. To convert minutes we divide number of second by 60. .
It will take him approximately 60 minutes to get to school.
Answer:
x is 5 and B is 66°
Step-by-step explanation:
Since the two lines are parallel then
A + B = 180°
8x + 74 + 2x + 56 = 180
Then x is 5
Since B is 2x + 56.
Then B is 2(5)+56=66°
Answer:
(a)
Step-by-step explanation:
and y = 2x - 3
Answer:
3. the numbers between -5 and 5
Step-by-step explanation:
Let set A= and set .
The solution set of A and B is the solution set of A∩B
The solution set of A is all the real number x which is greater than -5.
The solution set of B is all the real number x which is less than 5.
Therefore, the solution set of A∩B is all the real numbers between -5 and 5.
Hence, option (3) is correct.
