Answer:
x = 9.7
Step-by-step explanation:
The area of a triangle is A = b * h / 2 where A, b, and h are the area, base and height respectively. We know that A, b, and h equal 47, x, and x respectively so we can write:
47 = x * x / 2
47 = x² / 2
94 = x²
x = ±√94
In context, x can't be negative so the answer is x = √94 = 9.7.
Hey there!
We are looking for the circumference of the circle, which is the distance around it. We are given the area, which is the radius squared times pi.
First, we need to undo the area to find our radius.
113.04/3.14=36
We square root this to find the radius.
√36=6
Our radius is six. To find the circumference, we need to multiply the diameter by pi. The diameter is twice the radius.
6*2=12
12*3.14=37.68
Therefore, we will need 37.68 feet of trim to around the edge of the quilt.
I hope this helps!
Y-3=1/2(x+2)
To find the y-intercept, we must first get the equation in slope intercept form. Start off by distributing 1/2 into the parentheses.
y-3= 1/2x+1
Add 3 to both sides
y= 1/2x+4
The slope is whatever is in front of x, in this case, 1/2. The y-intercept is the number after that which would be 4
300° CCW is the same as 60° CW. N will show up where H is now.
The 3rd selection is appropriate.
45 multiply 0.22 = 9.9
45-9.9 = 35.1
