Answer:
<h2>A = 52.5 m²</h2>
Step-by-step explanation:
The formula of an area of a kite:

<em>e, f</em><em> - diagonals</em>
<em />
We have <em>e = 15m, f = 7m.</em>
Substitute:

22-6=16. 16÷4=4. Each ticket costs $4.
Answer:
3000 people
Step-by-step explanation:
4% teenagers --> 120 teenagers were there
120/4 means 1% so 30 is 1%
1% times 100 is 100% so 30 times 100 equals 100% so 3000 is 100% of the people at the stadium
Answer:
60cm^2
Step-by-step explanation:
We assume that is a circumscribing quadrilateral, rather than one that is circumscribed. It is also called a "tangential quadrilateral" and its area is ...
K = sr
where s is the semi-perimeter, the sum of opposite sides, and r is the radius of the incircle.
K = (12 cm) (5cm) = 60 cm²
_____
A quadrilateral can only be tangential if pairs of opposite sides add to the same length. Hence the given sum is the semiperimeter.
Answer:

Step-by-step explanation:
Given
Variation: Directly Proportional
Insects = 10 million when Rate = 2 million
i.e.
when 
Required
Determine the differential equation for the scenario
The variation can be represented as:

Which means that the rate at which the insects increase with time is directly proportional to the number of insects
Convert to equation
