B. All real numbers greater than -1
Answer:
1. A ring of grass with an area of 314 yd squared surrounds a circular flower bed. Find the width x of the ring of grass.
The radius of the circular flower bed = 10 yd.
2. Harriet has 80 m of fencing materials to enclose three sides of a rectangular garden. She will use the side of her garage as a border for the fourth side. Find the width x of the garden if its area is to be 700 m squared.
3. Sid cuts four congruent squares from the corners of a 30-in.-by-50-in. rectangular piece of cardboard so that it can be folded to make a box. Find the side length s of the squares, given that teh area of the bottom of the box is 200 in squared.
Step-by-step explanation:
Answer:
BC = 24
Step-by-step explanation:
since ABC is an isosceles triangle
<C = <B, then AC = AB
AC=AB
x+8 = 2x-1
subtract x from each side
x+8-x =2x-1-x
8 =x-1
add 1 to each side
8+1 = x-1+1
9 =x
BC = 3x-3
BC = 3(9) -3
BC= 27-3
BC = 24
First we need to findustries out how many bread pieces were used.
25-5=20 pieces used.
This means the fraction of bread used is 20/25, but that is not the simplified fraction.
20/25

5 5
=4/5
She used 4/5 of the loaf to make sandwiches.
X/(2-6) = y
Subtract first
x/-4 = y
multiply both sides by -4
x= -4y
Hope this helps! :)
