18. It would be the second graph. The third graph is eliminated as the boy takes a time period to shave, which means there should be a constant point (horizontal line) right after the first incline. The first one is eliminated as the boy takes a bath which requires another constant point in the graph.

Answer:
Circumference ≅ 195 mm
Step-by-step explanation:
The circumference of a circle is equal to:
Since we can replace that in the circumference equation giving us:
We know Diameter = 622 mm and pi = 3.14 so:
This triangle can be classified as an Acute Scalene Triangle.
It is an Acute triangle because all of its sides are acute (less than 90 degrees)
It is a Scalene triangle because all of its sides are of different lengths.
To find the missing angle degree we must subtract 61 and 78 from 180. We subtract them from 180 because all angles of a triangle add up to 180 degrees.
180 - 61 - 78 = 41.
So the missing angle (x) = 41 degrees.
Hope I helped!
Answer:
y = 11
Explanation:
8(y − 5) = 6y − 18
Simplify both sides of the equation
8(y − 5) = 6y − 18
(8)(y) + (8)(−5) = 6y + −18( Distribute)
8y + −40 = 6y + −18
8y − 40 = 6y − 18
Subtract 6y from both sides
8y − 40 − 6y = 6y − 18 − 6y
2y − 40 = −18
Add 40 to both sides
2y − 40 + 40 = −18 + 40
2y = 22
Step 4: Divide both sides by 2
2y / 2 = 22 / 2
y = 11
