Answer:
Option C. the volume of water in the tank is decreasing by 0.4L per hour
Step-by-step explanation:
step 1
Find the slope
we know that
The formula to calculate the slope between two points is equal to
we have
Substitute the values
The slope is negative
so
is decreasing
That means------> the volume of water in the tank is decreasing by 0.4L per hour
Answer:
4 degrees Celsius
Step-by-step explanation:
It is asking for the change in temperature, or the difference. In word problems like this it is asking for subtraction.
So you just need to subtract the temperature at noon from the temperature at 8 am.
18 - 14 = 4 degrees
Notice the picture below
in a rectangle, all angles are 90 degrees and the diagonals are equal
meaning the diagonals bisect each other, they cut in equal halves
so. those two sides are equal, and thus they make up an isosceles triangle
on the sides
if those two sides are equal, the angles they make on the other side are equal
so if angle D is 55 degrees, angle A is 55 degrees
and the missing angle is 180 - (55 + 55) or 70
that's just the left-side
now, angle "x" on the right side, is a vertical angle of that angle on the left,
and vertical angles are equal, thus x = 70
