Algebra is Faster And Better Than “Basic” Math
Just as multiplying two by twelve is faster than counting to 24 or adding 2 twelve times, algebra helps us solve problems more quickly and easily than we could otherwise. Algebra also opens up whole new areas of life problems, such as graphing curves that cannot be solved with only foundational math skills.
Answer:
r = 63 meters
Step-by-step explanation:
C=2πr
We know pi and C
396 = 2*22/7*r
396 = 44/7 *r
Multiply each side by 7/44 to isolate r
396*7/44 = 7/44 *44/7 *r
63 =r
Answer:
91 cents
Step-by-step explanation: 3 times 25 is 75
3 times 5 is 15 then 1 so add to together
If the rate continues, in nine years there will be about 300 employees
We can represent the pizza as 1. And every time we take a slice, we take percentage away. This pizza is cut up equally into 10 slices. So, if we take away a slice, we take away 1/10 of the pizza. What if Sally ate 6 slices? Same difference. She took away 6/10 of the pizza.
And to answer the question, "What <span>percentage of the pizza did Sally eat if she had six slices?"
We will convert the 6/10 into a percentage. First convert the fraction into a decimal then into a percent.
To convert a fraction into a decimal, simply divide it's numerator by it's denominator.
6/10 = 0.60
And to convert a decimal into a percentage, move the decimal point two places to the right and change it into a % sign.
0.60 = 60%
So, the answer to this question C) 60%
