Answer:
2 pints x 20 days = 40 pints
there are 8 pints in a gallon
so 40 divided by 8 = 5
so she drinks 5 gallons in 20 days
Step-by-step explanation:
See how many 5s there are in 47? There are 9 and also a leftover 2 which is your remainder.<span />
So for question 7 part A the picture will be a triangle similar to the the one that shows the umbrella's height. But the base will be 40 and the height will be 130.
for part B the angle of depression can be found using the trigonometric function of tangent.
tan x = 40/130
tan^-1 (tan x) = tan^-1 (40/30)
x = 17 degrees
I hope i am right
I hope this helps you
if two angles sum is 90 degree their name the relationship must be vertical.
a+b=90
