lawyer [7]

the highest batting average is of Ed's and that is 0.350 .

<u>Step-by-step explanation:</u>

Here we have , Make, Dan, Ed, and summer played together on a baseball team. Mike’s batting average was 0.349, dan’s was 0.2, Ed’s was 0.35, and sy’swas 0.299. We need to find Who had the highest batting average . Let's find out :

According to question we have following parameters as :

$Mike = 0.349\\Dan's=0.200\\Ed's=0.350\\Sy'swas=0.299$

Arranging these data from decreasing to increasing order we get :

⇒ $0.200$

⇒ $(Dan's)0.200$

Therefore , the highest batting average is of Ed's and that is 0.350 .

Angela has a cube with a length of one yard. Maya has a cube with a length of one meter. What do the two cubes have in common? L

Vlad1618 [11]

<h3><u>1) </u><u>Both cubes have approximately equal sides</u><u>.</u></h3><h3><u>2) The volume of both cubes is approximately equal .</u></h3>

Step-by-step explanation:

Here, let us assume there are two cubes A and B.

The side length of cube A = 1 yard

The side length of cube B = 1 meter

Now,as we know: 1 meter = 1.09361 yards ≈ 1 yard

So, we can say that, approximately, <u>both cubes have equal sides</u>.

Now, Volume of a Cube = (Side)³

Since, both cubes have approximately equal sides,

⇒Volume of cube A ≈ Volume of cube B

Hence, both cubes have approximately equal volume.
