To solve this problem, you would do 21 ÷ 25. After you have done this, you would have .84. You would then convert this to decimal form, which is 84%. The dog caught the frisbee in his mouth 84% of the time.
Answer:
Step-by-step explanation:
Recall that when we are factoring a polynomial, we are implicitly finding its roots. By finding a root, we are looking for a value of x (say c) such that p(c) =0. When this happens, our polynomial has the the polynomial (x-c) as a factor.
We are given the values of p at some values of x. We notice that p(5) = 0 and p(-12) =0. So, this means that our polynomial has as a factor the polynomials (x-5) and (x+12).
Luckily you are not required to use a ruler or be exact- so it just has to be in the range. I would (in pencil or erasable color) divide the line into 4 sections as guide points then determine where each of the sections would go. EX: If it was 4/10 I know it is closer to the 1/2 mark then the 1/4 mark and place the dot.
If you need to, find where the marks would be before simplified-- 3/10's half way guide point isn't 1/2 its 5/10.
Answer:
Right triangles
Step-by-step explanation:
A rectangle has 4 right angles (90°). If you cut the rectangles diagonally, you will create the triangles containing one of those right angles each.
Answer:
Step-by-step explanation:
Use the identity: a² - b² = (a + b)(a- b)
4 - 9w² = 2² - (3w²)
= (2 + 3w)(2 - 3w)
