Answer:
-1,3
Step-by-step explanation:
If two city’s are 14 miles apart and on a map they are 2 inches away. All you have to do is divide 14 by 2. Your answer is 7 miles per inch.
well, what we do is, simply get the area of the containing rectangle, is an 8x10, and then get the area of the circle, with a radius of half of 4.3 or r = 2.15, and then if we subtract the area of the circle from the rectangle's, what's leftover is the shaded part.
![\stackrel{\textit{\large Areas}}{\stackrel{rectangle's}{(8\cdot 10)}~~-~~\stackrel{circle's}{[\pi (2.15)^2]}}\implies 80-4.6225\pi ~~\approx~~65.5](https://tex.z-dn.net/?f=%5Cstackrel%7B%5Ctextit%7B%5Clarge%20Areas%7D%7D%7B%5Cstackrel%7Brectangle%27s%7D%7B%288%5Ccdot%2010%29%7D~~-~~%5Cstackrel%7Bcircle%27s%7D%7B%5B%5Cpi%20%282.15%29%5E2%5D%7D%7D%5Cimplies%2080-4.6225%5Cpi%20~~%5Capprox~~65.5)
Answer:
c) 18 units
d) 1 second
Step-by-step explanation:
h = -16t² - 4t + 20
c) t = 0.25
h = -16(0.25)² - 4(0.25) + 20
h = 18
d) -16t² - 4t + 20 = 0
4t² + t - 5 = 0
4t² + 5t - 4t - 5 = 0
t(4t + 5) - (4t + 5) = 9
(4t + 5)(t - 1) = 0
t = -1.25, 1
t = 1 second
Division is the splitting of large numbers (in this case) numbers into equal groups of smaller numbers.
Here are some terms you need to understand before you divide:
The number being divided is called the <em><u>dividend</u></em>.
The number that you're dividing by is called the <u><em>divisor</em></u>.
The answer that you get to the division problem is called the <em><u>quotient</u></em>.
For example:
Let's try dividing 4 ÷ 2 .
Since 4 is the number being divided, it is the <em>dividend</em>.
And since were are dividing 4 (the dividend) by 2, 2 is the <em>divisor</em>.
We need to try and find the quotient to solve 4 ÷ 2 .
Think of it this way;
There are 6 cookies and we need to divide them equally so that 2 people can have the same amount of cookies.
6 ÷ 2 = 3
You know the answer is 3 because 2 goes into 6 three times. 2 × 3= 6 (Since you asked a question about division, I'm guessing you know multiplication.)
3 for one person and 3 for the other.
So how many does each person get? 3 cookies, fair and square.
A nice way to check this problems is fact families, as I have mentioned before with the multiplication problem.
Hope this helps!
