We are basically given most of what we need to calculate the height of the cannonball.
We use the formula h = –16t+ vt + s to find the height requested.
Let v = 160
Let s = 10
Let t = time in seconds
Was the value of t included? We need to know t to plug into our formula.
You know everything else except for t. Go back to your notes to search for t. Afterward, plug the value of t and everything else given above into the formula and calculate to find h.
First you Change the mixed number to an improper fraction (14/3) then you simplify (1/4 X 7/3) and then you multiply 1/4 X 7/3 = 7/12 :)

Step-by-step explanation:
Michael's Weight: 
Al's weight: 
a) Ratio of Michael's weight to Al's weight:
b) This ratio simplifies to: 
c) Yes, If the exponent in each expression were negative, then we have:
Ratio of Michael's weight to Al's weight: 
This ratio simplifies to: 
The two ratios are not the same.
Answer:
option 2
Step-by-step explanation:
The problem can be solved using Pythagoras' identity for a right triangle.
The angle between due East and due North is 90°
The solution here involves using the Cosine rule.
let x be the direct distance between house and office, then
x² = 17² + 21² - 2(17)(21)cos90° → option 2
Note that since cos90° = 0 the equation reduces to
x² = 17² + 21² ← Pythagoras' identity
First we have to find the median
The median is 19 when we cross off all the numbers
Now we have 11 12 15 16 and 17 in the first quartile
Cross 11 and 12 and cross 16 and 17, off which leaves you with 15
Answer is option d
