Answer:
height = 7.78 mm, while base = 31.11
Step-by-step explanation:
First, create the equation "4x^2=242." After doing this, solve for x. Once you do this, you will find x as 7.78. The x value is your height. To find the base, multiply height by 4.
Answer:
answer would be the first choice.
Step-by-step explanation:
you would need to factor out x from the expression, then factor out -3 from the expression, factor the expression using a^2-B^2=(a-b)(a+b), afterwards you factor out the 4 from the expression, and then the 3x. Next you would factor out 2x+1, reduce the expression with x-5, reduce the numbers with the greatest common divisor 2, you then reduce the expression with x-3, multiply the fractions, distribute 2 through the parenthesis, distribute the 3x through the parenthesis, and that should be all.
The sun is 332608.6957 times bigger than earth, or 3.326086957*10^5 times bigger.
Answer:
3 days: 8 heads.
10 days: 1024 heads.
Step-by-step explanation:
If each time the hero cuts off all the heads, then the amount doubles each time. This can also be represented using powers of 2, with 2^n, where n is the number of days.
2^1 = 2, so two heads the first time he cuts it.
2^2 = 4, so four heads the second time he cuts it.
With three, 2^3 is 8 so there are 8 heads.
With ten, 2^10 is 1024 so there are 1024 heads.
<span>-(-7-9-20)+(-3+11-21)
= 7 + 9 + 20 - 3 + 11 - 21
= 47 - 24
= 23</span>
