Answer:
oki! Mizuki here to help! 12 will be your answer!
Step-by-step explanation:
Soo... The ratio of blue to green is 4:3 right?
and there are 21 balloons!
4 + 3 is 7! So we divide 21 by 7 and get 3!
Then we multiply 3 by the number of blue balloons(aka 4) and get 12!
F(x) is also known as y, so in this case, x is 3 and y is 7. Therefore, graph f passes through point (3,7).
2•14=28 which is the musicians
5•14=70 which would be the actors
The ratio would be 28:70

Hi hopefully this helps you!
Step-by-step explanation:
To find the area of a circle you can use the formula A = πr^2
The radius of a circle is just the diameter divided by 2. In this case we know the diameter is 3, so the radius is 1.5
A = π(1.5)^2
= 7.07
Because this is a semicircle, divide this area by 2
= 3.53429 in^2
Add up the area of this semi circle with the area of the rectangle
A = (3.53429) + (3x4)
= 15.53429 in^2
To find the circumference/ perimeter of a circle use this formula C = 2πR
C = 2π(1.5)
= 9.42478 inches
Again because this is a semicircle, divide by 2
= 9.42478 / 2
= 4.71239 inches
To find the perimeter of this entire shape add up the circumference of the semicircle and the rectangle's sides and bottom
P = 4.71239 + 4 + 4 + 3
= 15.71239 inches
So the final answer would be
A = 15.53 squared inches
P = 15.71 inches
Hope this helps! Best of luck in your studies <3
