What 3D figure/shape is it?
Answer:
#9 slope is -2, y int is 3
#10 slope is 3/4, y int is 0
Answer:
x = 185.458 ft
Step-by-step explanation:
When we draw a picture, we are able to see that we need to use sin∅ to solve this problem:
sin15° = 48/x
xsin15° = 48
x = 48/sin14°
To Find :
How many gallons of a 80% antifreeze solution must be mixed with 100 gallons of 20% antifreeze to get a mixture that is 70% antifreeze.
Solution :
Let, x gallons of 80% antifreeze solution is required :
So,

Therefore, 500 gallons of 80% antifreeze solution is required.
