Answer:
x=25
Step-by-step explanation:
25*25=625 therefore x= 25
Folding a paper will make it thickness become double from it before.
Unfolded paper has 1 thickness
1 times folded paper has 2 thickness
2 times folded paper has 4 thickness
3 times folded paper has 8 thickness
From here it is clear that the pattern is
. SInce the paper is 0.1mm, then the function would be:
f(n)=
x 0.1mm
Answer:
x = ±2√15
General Formulas and Concepts:
<u>Pre-Algebra</u>
- Order of Operations: BPEMDAS
- Equality Properties
<u>Algebra I</u>
Step-by-step explanation:
<u>Step 1: Define</u>
x² = 60
<u>Step 2: Solve for </u><em><u>x</u></em>
- Square root both sides: x = ±√60
- Simplify: x = ±2√15
<u>Step 3: Check</u>
<em>Plug in both solutions of x to verify it's a solution.</em>
x = 2√15
- Substitute: (2√15)² = 60
- Evaluate: 4 · 15 = 60
- Multiply: 60 = 60
x = -2√15
- Substitute: (-2√15)² = 60
- Evaluate: 4 · 15 = 60
- Multiply: 60 = 60
Here we see that both solutions do indeed work.
∴ x = ±2√15 are both solutions to the equation.
Answer: men = 15 , women = 12
Step-by-step explanation:
Ratio of men to women = 5:4
Total ratio = 9
number of people = 27
number of men = ration of men / total ratio x total number of people
That is :
number of men = 5/9 x 27
number of men = 3
Number of women = ratio of women / total ratio x number of people
That is :
number of women = 4/9 x 27
number of women = 12
I think maybe 8 times because you have 1 per 6 chances with every throw and then multiply that with 48 times
