2x7/5+1/2
2x14+5x1/10
28+5/10
33/10=3 3/10
or 3.3
Answer:
Here are my hints. You can solve it yourself
1/ xy = -12 --> x = -12/y
2/ (-12/y) + y = -1 --> -(12/y) + (y²/y) = -1 --> -12 + y² = -y --> y²+y-12=0
3/ From y²+y-12=0 we can find y then use y to find x and then do your
(x+3) * (y+3)
Answer:
2 feet of fabric
Step-by-step explanation:
The correct answer should be 2 & 1/2 batches
2/7 + 2/7 is 4/7 and half of a batch would bring it to 5/7
Answer:
About 22.2 square feet
Step-by-step explanation:
First, you need to find the area of the full circle. The area of a circle is \pi r^2, which in this case is:
Now, since the sector is only 50 out of the total 360 degrees in a circle, you need to multiply this value by 50/360, which yields and area of about 22.2 square feet. Hope this helps!
