The reciprocal of a number x is 1/x
The reciprocal of 5 is 1/5
The reciprocal of 6/11 is 1/6/11 = 11/6
18 students are 100%-37,5%-40%=22,5%
So we know that 18 students equal to 22.5. And we are looking for the anwser what 100% of students is.
SO:
x students - 100%
(22 + 1/2)x =18×100
(22 + 1/2) can be represented as just 25.5
-//- = 1800
we need to divide bot sides by 25.5
x = 1800 / 25.5
... x = 80
If I understand what kind of answer this question is asking for it should be .12 mile above sea level.
Answer:
86° Fahrenheit
Step-by-step explanation:
F=1.8C + 32
C=30°
Plugging into the formula:
The Fahrenheit for 30° Celsius using the given formula is 86° Fahrenheit.
Since you're given the base for the perimeter of the rectangle, you can solve this question quickly.
First, you multiply 21 by 2, because there are two bases to a rectangle.
You'll get 42, and you will have to do 60-42 to find the perimeter for the remaining two sides.
60-42 will give you 18, so you can divide that by 2 because there are two other sides, giving you 9.
Now you have the side lengths 21 and 9. Area is base*height, so you can multiply 21*9 and get 189.
Therefore, the area of the rectangle is 189 meters
