Using the Typing Speed of 60 words per minute, it would take Krista about 8.33 minutes to type a 500-word essay.
This question deals with rate problems, specifically with typing speed. Krista can type 60 words per minute. We know that her essay contains 500 words.
Therefore, to find out how long it will take her to type it, we need to divide the total number of words by her speed. Let's do the calculation:
500 words / 60 words per minute = approximately 8.33 minutes
So, it would take Krista about 8.33 minutes to type her essay.

Step-by-step explanation:
We are given the polynomial:
Part A: What is the correct factorization of over the integers?
We need to factorize the term
Factorizing by grouping:
So, factors of the term are
Part B: What method is used to factor p(x)=8x3+12x2+2x+3?
The method used to factor the given polynomial is grouping.
We group the terms and then find the common terms in that specific group

Answer:
4ft.
Step-by-step explanation:
So, due to the shape being a triangle you could split the triangle in two to determine the height. This means that its essentially two right angle triangles beside one another with the hypotenuse being 5 ft long and its base being 3ft long. ( because we split the base by 2 so 6/2=3) Now we can perform the pythagorem theorum to solve for the wanted side (height). The pythagorem theorum is the hyptenuse squared equals one side squared plus the other side squared but considering we do not have one of those sides (height) we must re-organize the formula. SO the formula we will be using is hypotenuse squared minus side squared equals height squared.
Therefore,
5(squared) - 3(squared) = x(squared)
25-9=x(squared)
16=x(squared)
square root of 16=x
4=x
Finally, state your results... so we could say that due to our results the height of the tent would be 4 ft long.
