Answer:
The correct option is B.
Step-by-step explanation:
The area of triangle is

Where, b is the base of the triangle and h is the height of the triangle.
It is given that the base of the triangle is 10 inch and the height of the triangle is 14 inch.
The area of given triangle is



Therefore the area of triangle is 70 square inch and the option B is correct.
Answer:
600 seats
Step-by-step explanation:
We know there is 120 seats on a balcony and that is
of the total seats, we want to find the total number of seats so,
120 seats = 
We know that a whole fraction sums to 1 so for example 
120 seats = 
Multiply both sides to make it a whole fraction
600 seats = 
So if there is 120 seats and that number is only
of the total number of seats then the total number of seats is 600


y = quantity, for example:
I want to buy 1 bracelet =
1×7 = 7 + 1 = 8$ per bracelet
Answer:
x² + (y + 8)² = 81
Step-by-step explanation:
Centre (h,k) = (0,-8)
radius (r) = 9
(x - h)² + (y - k)² = r²
(x - 0)² + (y + 8)² = 9²
x² + (y + 8)² = 81
