Answer:
x= 3 and x= -3
Step-by-step explanation:
x^2 -9 = 0
Factor x^2-9
(x+3)(x-3)
If x+3=0, then x= -3
If x-3=0, then x= 3
<h3>The height of the tree is 55 feet</h3>
<em><u>Solution:</u></em>
Let,
Height of tree = x
Shadow of tree = 40 feet
Height of man = 5.5 feet
shadow of man = 4 feet
Set up a proportion comparing the height of each object to the length of the shadow.
Therefore,
Thus height of the tree is 55 feet
Answer: D) Janelle can type 1/4 of a page in 2/3 of a minute
Step-by-step explanation:
Option A is wrong because based on the constraints, Janine would type less than 3/8 of a page in anything less than a minute. 8 > 3/8.
For that same reason, option B is wrong as well. 2 > 3/8.
1/2 > 3/8 so Option C is wrong for the same reason as the options above.
To test option D;
If Janine can type 3/8 of a page per minute, how much can she type in 2/3 minutes.
Assume the much she can type is x;
3/8 : 1
x : 2/3
1x = 3/8 * 2/3
x = 1/4
<em>Option D is therefore correct. </em>
