rearrange the equation to where you set it equal to 0 by moving the 25 over.
n2 - 8n -9 = 0
now factor
(n-9)(n+1)
so n1 = 9
n2 = -1
Answer:
6045000000000000000000000 kg.
Step-by-step explanation:
We have been given that the mass of Earth is 
kg. The mass of the Moon is 
kg.
To find the total mass we will add mass of Earth and Moon.
First of all let us convert the given masses in standard form.
Therefore, the mass of Earth and Moon is 6045000000000000000000000 kg.
So decrease is 375-250=75
so convert 75/375 to percent
percent means part out of 100 so
x/100=x%
divide 125/375=0.3333/1
multiply by 100/100=33/100=33%
the answer is 33% or B
65% of the total expenses is for marketing, in which 500,000 is the total.
First, change the percentage into decimal
65% = 65/100 = 0.65
Next, to find the amount budgeted for marketing, multiply the total with the decimal
0.65 x 500000 = 325000
$325000 is used for marketing
hope this helps
