Answer:

Approximate decrease is 70%

Step-by-step explanation:

The percent decrease is the change over the new original / final value. The change between the old and the new is 850 - 500, which is 350. Thus the approximate percentage difference is

350

500

A quick way to turn anything with a denominator that starts with 5 and any number of zeros after it ... is to multiply both the top and bottom by 2. That is, that turns the ratio above to:

700

1000

Since a percentage is a number of 100, not 1000, just divide everything by 10. That means take away a zero from each number, which gives you a fraction of:

70

100

Thus, the result is 70/100, or 70%.

The sum of the squares of two consecutive negative integers is 61. Find the smaller of the two integers

Marysya12 [62]

$x^2+(x+1)^2=61\\ x^2+x^2+2x+1-61=0\\ 2x^2+2x-60=0\ \ /:2\\ x^2+x-30=0\\ \Delta=1^2-4\cdot(-40)=1+120=121\ \ \Rightarrow\ \ \sqrt{\Delta} =11\\ \\ x_1= \frac{-1-11}{2} = \frac{-12}{2} =-6,\ \ \ \ x_2= \frac{-1+11}{2} = \frac{10}{2}=5\\ \\Ans.:x=-6$
