Answer:
Step-by-step explanation:
Given
See attachment
From the attachment, we have:
First, we need to calculate length LM,
Using Pythagoras theorem:
Collect Like Terms
Solving (a): 
Substitute values for MN and LN
Solving (b): 
Substitute values for LM and MN
Solving (c): 
Substitute values for LN and LM
Solving (d): 
Substitute values for LM and LN
The answer is 12
Explanation: as you replace -2 it will give 4 so when u add 4 to 8 it equals to 12
10 percent of 11.50 is 1.15. Subtract that from 11.50 and you would get 10.35. The sale price would be $10.35
Yes should be the right answer
Answer:
$7
Step-by-step explanation:
Hey there
to solve this kind of problem we use the formula:
<h3>
</h3><h3>if we solve it :</h3>
First, converting R percent to r a decimal
r = R/100 = 5%/100 = 0.05 per year,
then, solving our equation
I = 70 × 0.05 × 2 = 7
I = $ 7.00
The simple interest accumulated
on a principal of $ 70.00
at a rate of 5% per year
for 2 years is $ 7.00.
