*The diagram is attached below.
Answer:
Circumference of Green Circle = 138.16 m
Circumference of Blue Circle = 69.08 m
Step-by-step explanation:
The radius of the green circle = 22 m
Radius of the blue circle = ½ the radius of the green circle = ½*22 = 11 m
Circumference is given as C = 2πr
Circumference of the Green circle = 2*3.14*22 = 138.16 m
Circumference of the Blue Circle = 2*3.14*11 = 69.08 m

Answers
Answer:
√24 because it's lies on between of√16 and√25.
The only square root that falls between 4 and 5 is √24.
What is Number system?A number system is defined as a system of writing to express numbers.
We can estimate the value of each square root and see which one falls between 4 and 5:
The value of √10 is less than 4 because √10 is, 3.16
√14 is less than 4.5 because √14 value is 3.76
√24 is greater than 4.5 because √24 value is 4.89
√32 is greater than 5 because 5 x 5 = 25, and √32 is slightly smaller than 5.
Therefore, the only square root that falls between 4 and 5 is √24.

Answer:
Part A:

Step-by-step explanation:

-70 -70
_______________
130=10x
x=13
Answer:
200-70= x
x/10=W
Step-by-step explanation:
$200 is the amount he wants save.
He already saved $70. (subtracting 70 from 200 gives me 130)
130 is what he still needs so if i divide that by 10 ( the amount hes putting in each week). this leaves me with 13. 13 is the amount of weeks left until he reaches his goal.

Put f(x) = x2 + 3 in y2.
Answers
Answer:
(X2+3)2
Step-by-step explanation:
First, you have to substitute in what f(x) equals for y since f(x) stands for y.
By doing this, the equation turns into (x2+3)2, because x2+3 is y, and 2 because the original equation way y2.
After you substitute, the answer is (x2+3)2.
How wide is an 80" widescreen TV (MEASURED DIAGONALLY) if it has a height of 48”?
Answers
Answer:
64"
Step-by-step explanation:
Pythagoras theorem
√(80²-48²)
√4096
=64
Answer:
Width = 64"
Step-by-step explanation:
It forms a right angled triangle. We can use Pythagorean theorem to find the base of the triangle
Base² + altitude² = Hypotenuse²
base² + 48² = 80²
base² + 2304 = 6400
base² = 6400 - 2304
base² = 4096
base = √4096
base = 64
Width = 64"
