The formula for half-life is:
A is the amount remaining, P is the initial amount, t is the time that has passed, and h is the half-life of the substance. Plug in the values that you know and solve:
Rounded to the nearest whole number, the density of the substance was about 13<span>mg / cm².</span>

Answer: x=-5 or x=2
Step-by-step explanation:
x^2+3x-10=0
x^2+5x-2x-10=0
x(x+5)-2(x+5)=0
(x+5)(x-2)=0
x+5=0 or x-2=0
x=-5 or x=2
Uhm I don’t know but hope you find it have a nice day doe! Little one! :)
Answer:
0.418878 I think thats the answer look in the explanation if you need.
Step-by-step explanation:
Compute answer to nearest "whole" number: A manufacturing process produces items whose weights are normally distributed. It is known that 22.57% of items produced weigh between 100 grams and the mean" weight 49.18% weigh between the "mean and 190 grams." Calculate the standard deviation.
