Answer: There are 4 people who only go to the game on Saturday.
Step-by-step explanation:
Let the number of people go on Saturday be n(A).
Let the number of people go on Sunday be n(B).
Since we have given that
n(A) = 8
n(B) = 12
n(A∪B) = 16
According to rules, we get that

So, n(only go on Saturday) = n(only A) = n(A) - n(A∩B) = 8-4 = 4
Hence, there are 4 people who only go to the game on Saturday.
Area of ∆ = 1/2 times its base × height
=1/2 × 4 × 5 UNIT²
=10 unit²
Area of semicircle = πr²/2
= (3.14)(4)²/2
=25.12 unit²
Therefore area of figure= 10+25.12 unit² = 35.12 unit²
Hope it helps!
Answer:

Step-by-step explanation:
we know that
The length of segment B''C'' is equal to the length of segment BC multiplied by the scale factor
step 1
Find the length of segment BC
the formula to calculate the distance between two points is equal to

we have the points
B(1,-3),C(-3,-3)
substitute the values



The segment B''C'' is equal to the segment BC multiplied by the scale factor
The scale factor is 3
so


substitute

Answer:
the answer is B
Step-by-step explanation:
15 percent x 0.75
= (15/100) x 0.75
= (15 x 0.75)/100
= 11.25/100 = 0.1125
C=2pi*r; circumference formula
a=pi*r^2; area formula
It says the circumference is pi/2; so undo that by using the circumference formula to solve for r(radius);
2pi*r=pi/2
pi crosses each other off, making 2r=1/2
(When something crosses itself out it becomes a 1)
2r=1/2
r=.25 (because 1/2 is 0.5, and 0.5 divided by 2 is .25)
Now use the r you have in the area formula.
a=pi*r^2
.25 squared is .0625
1 divided by .0625 is 16, so now you have
a=pi*.0625 this will get you 1/16th of pi, or pi divided by 16.
(1/16th if pi is the same as pi divided by 16)
.0625pi=pi/16
