Answer:
If the slopes of the lines are both zero, the lines are horizontal and are parallel by definition. Since the slopes of vertical lines are undefined and not considered equal, vertical lines will not be considered.
I hope this helps you :)
As we are given
Car is driving at the rate of 58km per hour
First we will have to convert it into miles per hour
As we know that 1 km per hour =0.621371 miles per hour
So we can say 58km per hour=58*0.621371 miles per hour=36.0395 miles per hour
We are supposed to find -"How much time will it take to drive for distance of 32 miles"
As we know that
Distance=Speed*Time
Lock key is 042
Step-by-step explanation:
- Step 1: Through each clue, eliminate numbers to find the lock.
738 - all digits are wrong
⇒ the numbers are not 7, 3 or 8
380 - one digit is right but in the wrong place
⇒ since 3 and 8 are wrong digits, 0 is the right digit but place is wrong
682 - one digit is right and in its place
⇒ since 8 is a wrong number, the right digit could be 6 or 2
614 - one digit is right but in the wrong place
⇒ since 6 was in the same position in the previous clue, it can be concluded that 6 is also wrong.
206 - two digits are right but are in the wrong place
⇒ from the above clues 0 and 2 are the right digits.
∴ 0, 2 and 4 are the right digits.
- Step 2: Find the positions of the digits.
0 can't be in 2nd or 3rd position based on the clues.
2 should be in the 3rd position.
⇒ Order is 042
Answer:
Step-by-step explanation:
a + d + m + r = 16
a = d + 3......d = a - 3
a = m + 2.......m = a - 2
m = r + 1.......r = m - 1.......r = (a - 2) - 1......r = a - 3
a + (a - 3) + (a - 2) + (a - 3) = 16
4a - 8 = 16
4a = 16 + 8
4a = 24
a = 24/4
a = 6 <==== andrew scored 6
d = a - 3.....d = 6 - 3.....d = 3 <=== danielle scored 3
m = a - 2......m = 6 - 2.....m = 4 <==== mel scored 4
r = a - 3......r = 6 - 3 ......r = 3.......renee scored 3
