The half-life is 29 years.
116 : 29 = 4
So we will have 4 periods of half-life:
( 1/2 )^4 = 1/16
150 g * 1/16 = 9.375 g
Answer:
9.375 g of strontium -90 will remain after 116 years.
Given:
Area of the trapezoid is 39 ft².
The image contains a measurement of 11 ft and 15 ft on its bases.
Area of a trapezoid = (a + b)/2 * h
39 ft² = (11ft + 15ft)/2 * h
39ft² = 26ft/2 * h
39ft² = 13ft * h
39ft² ÷ 13ft = h
3ft = h.
The height of the trapezoid is 3 feet.
Answer:
-2/1 or -2
Step-by-step explanation:
On the graph plot the points, draw a line to connect them, draw a right triangle, the up will be the 2 and the across is the 1. It is negative b/c it slopes down to the right.
Mark me as brainliest if this helps!
I think you mean "a set of three points". What I would do is take one point, find the slope from that point to another one, and then find the slope from the same starting point to the third one. If the (absolute values of the) slopes from the same starting point to each of the others are equal, then the three points are collinear.
