Answer:
26.1miles
Step-by-step explanation:
If three cities A, B and C form a right triangle on a map, and the Cities B and C are the furthest apart, then the distance between cities B and C will be the hypotenuse of the triangle.
If cities A and B are 14 miles apart, then |AB| = 14miles
Also if cities A and C are 22 miles apart, then |AC| = 22miles.
To get |BC| which is the distance between cities B and C, we will use the Pythagoras theorem.
|BC|² = |AB|² + |AC|²
|BC|² = 14²+22²
|BC|² = 196+484
|BC|² = 680
|BC| = √680
|BC| = 26.1miles
This means that cities B and C are 26.1miles apart
Answer: 0.52
Step-by-step explanation: 8 out of the 15 years were in the 90s. So 8/15 is 0.52
Answer:
$44
Step-by-step explanation:
First, find how much he was making originally:
Multiply the number of hours he worked by the amount he got per hour:
20(8)
= 160
Then, find how much he gets now:
24(8.50)
= 204
To find his total weekly pay increase, find the difference between them:
204 - 160
= 44
So, his total weekly pay increase is $44
3y = 2x + 6
x + y = 7
y = 7 - x
3(7 - x) = 2x + 6
21 - 3x = 2x + 6
21 - 6 = 2x + 3x
15 = 5x
15/5 = x
3 = x
x + y = 7
3 + y = 7
y = 7 - 3
y = 4
Solution is (3,4)
