The area of a square is:
A=s^2, solve this for s
s=√A
The "diagonal" is the hypotenuse of a right triangle with legs of length s.
By the Pythagorean Theorem:
d=√(s^2+s^2)
d=√(2s^2), and since we found that s=√A earlier:
d=√(2A), and since we are told that A=128m^2
d=√256
d=16m
19 × 1.03 = 19.57
The answer is 19.57.
$3-$2.50=$0.50 (difference in $ of each hot dog and hamburger)
take 25 total as all hamburgers
25x $2.50=$62.50
$70.50-$62.50=$8
$8 ÷ $0.50 = 16
16 hot dogs, 9 hamburgers
Check :
16 x $3 = $48
9 × $2.50 = $22.50
$48+$22.50=$70.50
First lets find -8.2 x 10 = -82 know we find 82^5 which is 82*82*82*82*82
-82*-82=6724 and then 6724*-82= -551368 and then -551368*-82 =45212176 and then 45212176*-82= -3707398432 and finally -3707398432 is our answer i checked the calc to after i did the hard math that took me forever i had some help from the calc and i got this hopefully this helps
