Answer:
Total cost= $86.25
Step-by-step explanation:
Giving the following information:
Discount= 10%
Nill= $82.5
Tip= 15%
<u>First, we need to calculate the discounted price:</u>
Discount price= 82.5 / 1.1= $75
<u>Now, the tip:</u>
Tip= 75*0.15= $11.25
<u>Finally, the total cost:</u>
Total cost= 75 + 11.25
Total cost= $86.25
Answer:
<em>83.33%</em>
<em>Total no. of students = 720</em>
<em>No. of students who failed = 120</em>
<em>Therefore no. of students passed = 720 120= 600</em>
<em>Therefore pass percentage = 600/720* 100 = 83.33%</em>

Answer and Step-by-step explanation:
The sides we have are 7, 
, and 
.
The square root of 80 is less than 9 but greater than 8 (because 
is 64, 
is 81, and 80 is in between those two values), and the square root of 31 is definitely less than the square root of 80.
So, is the longest side.
1) The square of is: 
2) The sum of the squares of the two shorter sides is:
3) Since the square of the longest side is equal to the sum of the squares of the two shorter sides, by the Pythagorean Theorem, the triangle is a right triangles.
Hope this helps!
The patio is 22 feet long.
The act of measuring is the practice of comparing a physical quantity with a recognized standard quantity of a like kind. A base unit, sometimes called a fundamental unit, is a unit used to quantify a base amount. A base quantity is a physical quantity that is part of a traditionally selected subset of physical quantities but cannot be stated in terms of the other physical values in the subset.
Given the scale used is 1cm which represents 5.5 feet.
measure of patio on scale drawing is 4cm.
then it's length is 5.5 × 4 = 22 feet
These measurements pertain to the following: length, mass, time, electric current, temperature, amount of a substance, and luminance. Here are the seven base units' definitions: Distance: meters (m) Metric length is measured in meters.
hence we get the value of the length of the patio as 22 feet.
