Into 3 parts meand sivided by 3 means times 1/3
1/6 divided into 3 parts means 1/6 times 1/3=1/18
1/18 was in each mound
A is answer
Answer:
24GB
Step-by-step explanation:
75.99-59.99=16 This is how much extra money was paid.
16/4=4 Divide this by the cost per GB.
20+4=24GB Add the 20GB included in the plan.
Slope (m) of a line = (y2-y1)/(x2-x1)
So for line AB, the slope is (3-2)/(-1-1)
= 1/-2 = -1/2
For line AC = (3--1)/(-1--3) = (3+1)/(3-1)
= 4/2 = 2
For line BC = (2--1)/(1--3) = (2+1)/(1+3)
= 3/4
In order for an angle (<) to be right, it must be 90°, so the two lines making the right angle must be perpendicular. Perpendicular lines by definition have slopes that are the negative reciprocal. That means that you change the sign of one line's slope (m) and divide 1 by it:
m2 = 1/-m1
So for lines AB and AC: m(AC) = 1/-m(AB),
does 2 = 1/--1/2? YES!! 1/--1/2 = 1/1/2 = 2, so < BAC is 90° and therefore a right <
How about for lines AB and BC: m(BC) = 1/-m(AB), does 3/4 = 1/--1/2? NO, because 1/--1/2 = 1/1/2 = 2, not = to 3/4, so < ABC is not right
How about our last < BCA: m(AC) = 1/-m(BC), does 2 = 1/-3/4? NO, because 1/-3/4 = -4/3, not = to 2, so < BCA is not right
So yes, the triangle is a right triangle because < BAC is right (=90°)!
40 cents is the answer but brainy asked me to add some more words. How u doing?
Answer:
Step-by-step explanation:
A(t) denotes the amount of oil in the barrel at time t.
As the amount of oil is decreasing at a rate proportional to the product of the time elapsed and the amount of oil present in the barrel,
Here, k is a constant term.
As a 100-gallon barrel initially contains half-full of oil,
