Answer:
Missing side=25 units.
Area of the figure= 470 sq units.
Step-by-step explanation:
The figure is made up of a rectangle and a triangle.
To get the base of the triangle, we find the difference between the two parallel sides, that is, 16ft and 31 ft.
31ft-16ft=15ft
The height of the triangle is 20 since it is parallel and equal to the length of the rectangle.
We therefore use pythagoras theorem to find ?
a²+b²=c²
15²+20²=c²
625=c²
c=25
ii. The figure is a trapezium therefore we use the following formula to find the area.
A= 1/2(a+b)h, where a and b are the two parallel sides. and h the distance between them.
=(1/2)(31+16)×20
=470 sq units
Answer: 
.
Step-by-step explanation:
Given : Total kinds of pasta = 5
Total kinds of flavors = 4
The probability of selecting rigatoni = P(rigatoni) = 
The probability of selecting pink sauce = P(pink sauce) = 
Since both kinds and flavour are basically independent factor to get choose.
So, P(rigatoni and pink sauce)= P(rigatoni) x P(pink sauce)
Now , the probability that Ana ends up with rigatoni, pink sauce, or both would be :
P(rigatoni or pink sauce) = P(rigatoni) + P(pink sauce) - P(rigatoni and pink sauce)
Hence, the required probability is .
