Answer:
28.2743 square feet (28 square feet, rounded)
Step-by-step explanation:
The area of a circle is given by the equation
Area = πr^2
Plug in 3 for the radius
Area= π(3)^2
3 squared is 9
Area= 9 π
Area= 28.2743 square feet
Rounded to the nearest square foot, the area of the circle is 28 square feet.
On a die there are 3 even numbers. We want to know the probability that rolling a die we get 3 or an even number. So there are 4 positive outcomes out of 6.
4/6=2/3
Answer:
y=3x
Step-by-step explanation:
In this case, the ratio between sugar and water is 0.5 : 1.5 or 1 : 3.
That means that you need three cups of water for every cup of sugar.
In order to put this into an equation, the slope would be 3/1 or simply 3, and the y-intercept is 0. Even if you used the 0.5 : 1.5 ratio, the slope would be the same since 1.5 / 0.5 = 3.
5) The slope is: 6
6) Answer: y=-1/2x+3
7) Answer: The slope is: -8, the y intercept is: 6
8) Answer: y=8x+30
Have a good day and a hug :D づ◡﹏◡)づ
