Adrug that it will decrease the bacteria cells by 5% every hour. if you start with 1500 bacteria cells, how many will be present after 8 hours? (i need this written as a y= equation)

after 8 hours there are 995 bacteria cells left

let y be the amount after 8 hours

the multiplying factor is 100 - 5 = 95 % = 0.95

y = 1500 × = 995

answer: option a.

step-by-step explanation:

you know that the quadrilateral opqr ( a four sided figure) is inscribed in circle. this means that all its vertices are on the circle.

then, by definition, the opposite angles of the quadrilateral are supplementary, this means that the sum of their measures is 180 degrees.

you can observe in the figure that the angles ∠opq   and the angle ∠orq   are opposite, therefore:

then, can be used to d to calculate the measure of ∠opq

= 5

step-by-step explanation:

to find the 15th term substitute n = 15 into the nth term formula

= (- 3 × 15 ) + 50 = - 45 + 50 = 5
