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.
'Of' in math means 'multiplied by,' so the equation that we can set up is:
So your answer is 320.
To do this first we will take the fraction and turn it into decimal form. To do this we will divide the numerator and the denominator.
7 ÷ 16 = <span>0.4375
Now to take it to percent form we will multiply by 100.
0.4375 </span>× 100 = 43.75%
So, 7/16 turned into a percentage would be 43.75%
Hope I helped ya!!
Answer:
the number is 10
Step-by-step explanation:
3x + 10 = 6x-20
