Answer:
Area = 78.5
Step-by-step explanation:
31.4 = 2 x pi X r
r = 31.4/(2xpi) = 31.4(2 x 3.14) = 5
Area = pi x r^2 = 3.14 X 5^2 =3.14 x 25 = 78.5 units^2
Answer:
well it looks like as each week is going by the puppy is gaining less weight cause at first 5 is added and then 4 so maybe the next week 3 is added
The correct choice is w-23=84.
Letting w be the number of wolves on January 1, we know that there are 23 fewer the next year which is given by w-23. We also know that this is a total of 84, so w-23=84.
Answer: The TV is 48 inches wide.
Step-by-step explanation: To find the solution to this equation we must use the Pythagorean theorem. The Py. Theo. is basically the formula :
a^2 + b^2 = c^2 You say this as "A squared plus b squared equals c squared"
To use this formula you must plug in the given values of a and b, to find c. A and b represent the two bases of the triangle, while c is the hypotenuse. In this equation we already have the value of c and a. We need to find b, but in order to do that we use a different formula. We use : c^2 - a^2 = b^2
See :
52^2 - 20^2 = b^2 *The ^2 means "to the power of" aka an exponent*
2704 - 400 = b^2 *When dealing with ^2, all you do is multiply the number by itself*
2304 = b^2 *Next, we find the square root of our current number.*
48 = b
*Another way to solve this equation is to memorize all the Pythagorean Triples. With that knowledge, you wont even need to use the formula because you will already know all three values. I hope this helped you understand :)
$3.50 I believe because the cost of ONE cup of coffee and 3 donuts is $3.70. And 2 cups and 2 donuts are 10 cents more. So ONE cup and ONE donut are $3.50 I beleve
