So before we can find the area, we first have to find the radius. We will do this by using the circumference formula, C = 2πr, to find the radius. Our equation will look like this: 30 = 2πr .
For this, all you need to do is divide both sides by 2π, and your answer will be 4.77 cm = r.
Now that we got the radius, we can solve for the area, which is A = πr^2.
A = π(4.77)^2
A = 22.7529π cm^2 or 71.48 cm^2
Each crayon weighs 9 grams. First, if the box is 15 grams, you need subtract 105 with 15, which is 90. Then, divide 90 by 10(the amount of crayons), and you get 9, so each crayon weighs 9 grams
Answer: (3x−2)(4x−1)
Step-by-step explanation:
<em>Start factoring with -11x.</em>
12x^(2)-11x+2
12x2+(−8−3)x+2
12x2+(−8x−3x)+2
12x2−8x−3x+2
<em>Factor the highest common denominator of each group.</em>
<em>Group the first two terms and the last two.</em>
(12x2−8x)+(−3x+2)
<em>Factor the highest common denominator (MCD) of each group.</em>
<em>4x(3x−2)−(3x−2)</em>
<em>Factoring the highest common denominator 3x−2.</em>
(3x−2)(4x−1)
Hi there! 5 bottles of water for $3 would make $0.60 per bottle. 0.6 * 15 = 9. That means 15 bottles of water should equal $9, but instead it is $8. Based on that, no. The costs for bottles of water is not proportional to the numbers sold. Basically, you can divide to find unit prices and multiply the number of another item to see if the numbers are proportional.
One of them is 30 degrees and the other is 60 degrees
