Answer:
option 4) x = 14 y = 7
Step-by-step explanation:
We are given a side angle and a side length so we can use trigonometry to find the solution
To find x we can use sine because the given side length is opposite to the angle so,
sin(60) = 
solve for x and you get 14 (make sure you check that your calculator is in degrees)
for either use Pythagorean theorem or remove sine by tangent.
Answer:
C
Step-by-step explanation:
Hose A:
60 gallons every 15 minutes mean:
60 / 15 = 4 gallons per minute
For Hose B:
If we put x = 1, we can find gallons (y) per minute (x)
y = 3 x
y = 3(1)
y = 3
That means 3 gallons per minute
Thus, the rate of Hose A is 1 gallon per minute more than the rate of Hose B. Option C is correct.
Answer:
72 + 8x
you would multiply 8 by 9 + x
138 x ? = 75
? = 75/138 = 0.544(3sf)
so about 54.35% (2dp) decrease
