Answer:
y= 90 degrees angle
Step-by-step explanation:
'y' is NOT the number of chairs in each row and column. It's the TOTAL number of
chairs, so it's the product of (chairs in each row) times (chairs in each column).
The problem says that those numbers are equal. So we would expect the TOTAL
to be a perfect square, and the number in each row and each column to be the
square root of the total. Since the total is 81, the number in each row and column
could be either +9 or -9 . Both answers are mathematically correct, but -9
doesn't make sense in the real world. So we know that +9 is the real answer.
Answer:
I think it's G
Step-by-step explanation:
Since a=8 root 3=8×3=24cm
Yh so I multiplied the 24cm by 12cm
12cm×24cm=288cm squared
and the square root of 288cm is 96 root 3 cm squared
Answer:
15 rides because I had gotten this correct on my test
rate of change for 2x+4y=10
here rate of change can be found by finding slope
the general form for slope is y=mx+b
isolating y on the left side:
2x+4y=10
4y=
-2x+10
from here slope is -1/2
Rate of change =-1/2
