Find t when
We have:
Substitute: and
Divide both sides by 22400
Take log of both sides
Apply law of logarithm
Solve for t
2/5x+y=7
subtract 2/5x on both sides
y=-2/5x+7
Answer: Sometimes
Step-by-step explanation:
This is a very tricky question. We know that in an isosceles triangle, two sides are the same. Because of this, we know that the right angle is always 90 degrees, and the other sides would be 45 degrees each because all triangles add up to 180 degrees. A right triangle could also be scalene, meaning none of the sides are the same, for example a scalene triangle could have sides of 44, 46, and 90 degrees. Rest assured, a right triangle will never be equalateral. Hope this helps :) Merry Christmas
There are 16 cups in a gallon. You have 2 gallons to begin with, so you have 32 cups to begin.
You give out 20 cups, so you only have 32-20 cups left. 32-20=12. You have 12 cups left.
