Answer:
s = 0.75 inches
Step-by-step explanation:
Let s = side length of the original square
s + 3 = side length of the new square
Area of a square = s²
A = s²
A = (s+3)²
A = s² + 6s + 9
Area multiplied by 25 = 25 * s²
So,
s² + 6s + 9 = 25s²
25s² - s² - 6s - 9 = 0
24s² - 6s - 9 = 0
8s² - 2s - 3 = 0
a = 8
b = -2
c = -3
s = -b ± √b² - 4ac / 2a
= -(-2) ± √(-2)² - 4(8)(-3) / 2(8)
= 2 ± √4 - (-96) / 16
= 2 ± √100 / 16
= 2 ± 10/16
s = 2 + 10/16 or 2-10/16
= 12/16 or -8/16
= 0.75 or -0.5
side length can not be negative
Therefore, s = 0.75
A = s²
A = (0.75)²
= 0.5625
A = (s+3)²
= (0.75+3)²
= 3.75²
= 13.95
Answer:
part 3: add how ever many years that much money
Part 4:
Step-by-step explanation:
part 3:for instance 0years = 1,000$ to 5years so it equals 6,000$ and so on if you dont get it ask me
and its the same calculation each time
Part4: write about how much money you earned and if you can retire with that in the first box, and in the second, write about how you will most likely earn the money
HOPE THIS HELPED I REALLY DO, MARK BRAINLIEST PLZ I NEED IT
Answer:
Records: $6000
Grass Seed: $4000
Toys: $3000
Food: $11000
Step-by-step explanation:
We have to use the number of degrees in each category in comparison to the total number of degrees in a circle, 360 degrees. Records is 90 degrees, so 90:360 = 1:4 = 1/4. So 1/4 of the total pie is $6000. For food, we add the other sub-category's costs, and subtract that from $24000.
2^10 = 1024 and 2013 - 1024 = 989
So there will be 10 + 1 = 11 digits Answer
