Answer:
<em>The elephants' moat should be 3.2 meters deep.</em>
Step-by-step explanation:
Suppose, the depth of the elephants' moat is
meter.
Width of the lions' moat is 5 meter and width of the elephants' moat is 4 meter.
Given that, the lion’s moat is 4 meter deep.
So, <u>according to the ratio of width and depth</u>, the equation will be.......

Thus, the elephants' moat should be 3.2 meters deep.
Solution:
we are given that
The magnitudes of the moon and Sirius are -12.5 and -1.44 respectively.
we have been asked to find approximately how many times is the moon brighter than Sirius?
The word magnitude is used by the scientist to describe the brightness of moon/star/object etc.
So we can find the brightness by dividing the given values. so we get

Hence we can say
The moon is 8.68 times brighter than Sirius.
Then c = 22 just keep adding 7
8+7=15 15+7=22
Answer:

if you don't have to simplify it, it is

Step-by-step explanation:
the equation for the area of a square is

substitute 72 for a

take the square root of both sides to cancel out the square on the s


if you need it simplified, find the perfect square that makes up 72. It is 36.

take the square root of 36
