Answer:
G = $612.50 when H = 46hours
Step-by-step explanation:
Given:
G = 18.75(H-40) + 500
Where,
G =Gross pay in dollars
H = Number of hours worked
If her gross pay one week was $612.50, what was the
total number of hours she worked that week?
G = $612.50 when H = ?
G = 18.75(H-40) + 500
612.50 = 18.75H - 750 + 500
612.50 = 18.75H - 250
Add 250 to both sides
612.50 + 250 = 18.75H
862.5 = 18.75H
Divide both sides by 18.75
862.5 / 18.75 = 18.75H / 18.75
46 = H
H = 46
If her gross pay one week was $612.50, her total hours worked = 46hours

We have given measure of angles of the triangle are in ratio 4 : 7 : 9 and here we need to find the measure of largest angle of a ∆.
Let, the three angles of a triangle be 4x, 7x, 9x.
We know that, Sum of all angles of a triangle is 180°.
4x + 7x + 9x = 180°
⇛20x = 180°
⇛x = 180°:20
⇛x = 9°
Now, finding largest angle by putting the value of “x”
- 4x = 4(9) = 36°
- 7x = 7(9) = 63°
- 9x = 9(9) = 81°
Hence ,the measure of largest angle is 81°.
