<span>Answer is C.
Explanation :-
Take the 1st case where Number of student(n) = 3 and Cost per student(c) is 24, we get n*c = 72
Take the 2nd case n = 6 and c =12, we get n*c = 72
Take the 3rd case n = 9 and c = 8, we get n*c = 72
By above observation we can say that product of Number of student and cost per student is 72 always.
Now for n = 12 we have to calculate c
n*c = 72
c = 72/12 = 6.
hence answer is option C.</span>
Answer:
you need to draw a triangle of given dimensions
Step-by-step explanation:
if B is right angle triangle then you can assume that either AB or BC is base and other one is perpendicular. So that makes AC hypotenuse
so let's assume BC is base of 6 cm. so draw a base of 6 cm line , name it BC
then draw a 90 degree angle on B keeping BC as Base . now length of perpendicular would be 4.5 cm. this perpendicular would be AB
no join A and C . length of AC should be 7.5 cm. if it's not then something is wrong in given question.
Hey there! :)
Area of triangles → (base × height) ÷ 2
The base and height are the 2 legs. You have to find the length of the other leg to find the area, using the Pythagorean Theorem.
a² + b² = c² → c² - a² = b²
c = 12
12² = 12 × 12 = 144
a = 10
10² = 10 × 10 = 100
144 - 100 = 44
√44 = 6.6
_____________________________________________________________
Area of triangles → (base × height) ÷ 2
Base: 10
Height: 6.6
6.6 × 10 = 66
66 ÷ 2 = 33
The area is 33
Hope this helps :)
Answer:
25
Step-by-step explanation:
The first step in simplifying the expression of the square root of 50 involves finding factors of 50. This just means we are trying to find two whole numbers that, when multiplied, equal 50. Since 50 is an even number, 2 is going to be a factor, and so we can rewrite 50 as 2 times 25.
<em>50</em>
- Step-by-step explanation:
<em>(-1) + 2 + (-3) + 4 + ... + (-99) + 100 =</em>
<em>= 2 - 1 + 4 - 3 + .. + 100 - 99</em>
<em>= 1 + 1 + .. + 1 </em>
<em>= 50×1</em>
<em>= 50</em>
