Answer:
Sarah is Correct
Step-by-step explanation:
If we are given the area of a circle as 44 Square Centimeter, we know that:
Area of a Circle
Circumference of a Circle 
Therefore, from the area, we can obtain the value of the radius to calculate the circumference of the circle:
Therefore:
Circumference of the circle
=23.51 centimeters.
Let the side of the square = a units, the area of the square = a^2 sq units
Area of the 4 semicircles = area of 2 circles = 2 pi r^2 = 2pi (1/2 a)^2
= pi a^2 / 2
Probability of a point in the unshaded square being picked) = area square / area of the total figure = a^2 / (a^2 * pi/2) = 1 / pi/2 = 2 /pi
which is approximately 65%
Answer:
a. y=5x-1
b. 2y=8-2x
y=8-2x/2
y=4-x
c. y=3x-3
Step-by-step explanation:
there you go
b or the second option
The correct answer for the question that is being presented above is this one: "w(w + 2) = 48." John has 48 square centimeter tiles he wants to use to create a mosaic. He wants the mosaic to be rectangular with a length that is 2 centimeters longer than the width.
Let w = width
Let (w+2) = length
Area = w(w+2).
You need to multiply three on both sides, add 6x to both sides, then divide by 4 on both sides. In the end, you will get y=3/2x+21/2.
