For the baseball camp, you would be paying $18.75 per day. For the basketball camp, you would be paying $20 per day. Judging by the prices, you would be more likely to have a better price for the baseball camp by 1.25. Yes, it isn't that much, but it's still worth it. Hope it helped!

Bingel [31]

There are 18 blocks across width and 48 blocks run up and down the length of quilt.

Solution:

Given, A quilt is 72 inches wide and 96 inches long.

The blocks have 4 inch sides

Finding number of blocks run across the width of quilt:

$\text { number of blocks across width }=\frac{\text { width of quilt }}{\text { length of each block }}$

$=\frac{72}{4}=18 \text { blocks }$

Finding number of blocks run across length:

$\text { number of blocks across length }=\frac{\text { length of quilt }}{\text { width of each block }}$

$=\frac{96}{4}=24 \text { blocks. }$

Finding number of blocks run up and down the length of the quilt:

$\text { number of blocks run up and down }=2 \times \text { number of blocks across length }$

$=2 \times 24=48 \text { blocks }$

Hence, there are 18 blocks across width and 48 blocks run up and down the length of quilt

Find 5 consecutive whole numbers if it is known that the sum of the squares of the first 3 numbers is equal to the sum of the sq

zlopas [31]

Let numbers be x-1,x,x+1,x+2,x+3

(x-1)^2 + x^2 + (x+1)^2 = (x+2)^2 + (x+3)^2

$( x^{2} -2*x+1)+ x^{2} +( x^{2} +2*x+1)= ( x^{2} +4x+4)+( x^{2} +6x+9)
$
$3 x^{2} +2=2 x^{2} +10x+13⇒
 x^{2} =10x+11⇒
 x^{2} -10x-11=0
$

x=11 or -1(not a whole number)
x=11
the numbers are 10,11,12,13,14
