Answer:
The shortest length of wire that can be used is 29.47 ft.
Step-by-step explanation:
To solve this problem we can follow the following steps:
1) We have the dimensions of the floor of the room. The shortest distance between its opposite corners is the diagonal. We calculate the diagonal using the Pythagorean theorem.

2) Since the speaker is on the ceiling, and the amplifier is on the floor, then 7 more feet of wire is needed to reach the speaker. <em>Observe the attached image</em>
3) The final distance (d) is:

Answer:
Yes, they are correct. Hernando divided 6 by 6.
Step-by-step explanation:
Given that:
Hernando ate 2/8 of a pizza for dinner.
Let the pizza be x. Then:
Hernando ate 
Then he gave the rest of the pizza to his friends
Hernando now carried out the following calculations to support his activities;


From the above calculation; we will see that Hernando divided 6 by 6 in both cases to get
.
Thus, the correct answer is:
Yes, they are correct. Hernando divided 6 by 6.
<span>(7x^4+x+14)/(x+2)
</span>(7x^4+x+14)----------------------|(x+2)
-14x³+x+14-------------------------7x³-14x²+28x-55------> q(x)
28x²+x+14
-55x+14
110+14=124------------------------> r(x)
<span>
</span>r(x)=124
b(x)=x+2
q(x)=7x³-14x²+28x-55
then
q(x) + r(x)/b(x)---------> (7x³-14x²+28x-55)+(124)/(x+2)
the answer is (7x³-14x²+28x-55)+(124)/(x+2)
10x and 2x is the answer to your question then do the equation
<u>Answer: </u>
Chance bought a surf board for 249. Now it's on sale for 221.10 and 11.20% is the discount.
<u>Solution:
</u>
Step 1:
Bought price= RS.249
Sale price=RS.221.10
Step 2:
Discount = bought price - sales price
Discount = 249 - 221.10
Discount = 27.9
Step 3:
Discount Percent = 
Substitute the value for Discount which we found in step 2 in the above formulae
Discount Percent = 
On simplification, we get

Discount Percent = 11.20%
Result:
Hence from the given data, we got the discount percent is 11.20%
