Answer:

Row 2

Step-by-step explanation:

6+5+3+0+4=16

4+5+3+5+6=23

7+1+4+5+3=20

4+2+5+6+3=20

23 is bigger than all of those so it would be row two.

Ramiro is 3/10 as tall as the flagpole. The flagpole is 5/9 as tall as the nearby tree. The tree is 32 2/5 feet tall. How tall i
djyliett [7]
x-\ Ramiro's\ height\\
y-\ Flapole's\ height\\
z-\ nearby\ tree\\\\
x=\frac{3}{10}y\\
y=\frac{5}{9}z \\z=32\frac{2}{5}\\\\\y=\frac{5}{9}*32\frac{2}{5}=\frac{5}{9}*\frac{162}{5}=18\\\\
x=\frac{3}{10}*18=5,4\\\\
Ramiro\ is\ 5,4\ feet\ tall.

An online retailer sells two packages of protein bars.
krok68 [10]
In order to find the price per bar, we divide the price by the amount of bars.  For the first one:

15.37/10 = $1.54 per bar

The second package:

15.35/12 = $1.28 per bar.

The 10-pack costs $1.54 per bar and the 12-pack costs $1.28 per bar.  The 12-pack has the better price per bar.

Now, let's look at the price per ounce.  We do this in a similar way.  We find the total amount of ounces in the package, and divide the price by the number of ounces.

In the first package, we multiply 10*2.1=21.  We have 21 ounces in the first package.  Now we divide 15.37/21.  In the first package, we have 0.73 dollars per ounce.

Now, let's look at the second package.  We start by multiplying 1.4*12=16.8.  There are 16.8 ounces in the package.  Now, we divide 15.35/16.8=0.91.  So, in the second package, we have 0.91 dollars per ounce.

The cost per ounce of the 10-pack is $0.73 and the cost per ounce of the 12-pack is $0.91.  The first package has the better price per ounce.

The better explanation is the second one, because I prefer the lower price per ounce, I think that the 1st pack is the better buy.
