Answer: 220
<u>Step-by-step explanation:</u>
Children (x): $2
Teens (y): $3, 
Adults: (z): $5
Quantity: x + y + z = 570 ⇒ x + + z = 570 ⇒ 1.75x + z = 570
Cost: 2x + 3y + 5z = 1950 ⇒ 2x + 3
+ 5z = 1950 ⇒ 2x + 2.25x + 5z = 1950 ⇒ 4.25x + 5z = 1950
Qty: 1.75x + z = 570 → 5(1.75x + z = 570) → 8.75x + 5z = 2850
Cost: 4.25x + 5z = 1950 → -1(4.25x + 5z = 1950 → <u> -4.25x - 5z</u> = <u>-1950 </u>
4.50x = 900
x = 200
Teens (y):
y = 
= 
= 150
Quantity: x + y + z = 570
200 + 150 + z = 570
350 + z = 570
z = 220
The independent variable would be “d meters” because the amount of time depends “dependent variable” on the height of the fall
Answer:
Step-by-step explanation:
If the given variables are 127 hours of sleep per week for a Giant Armadillo, and 98 hours of sleep per week for a Platypus, to determine which animal gets the most sleep, first multiply the total hours of sleep of each animal per week to the total number of weeks In a year, which is 52. Once you get the answers, which are 6,604 hours of sleep in a year for the Giant Armadillo and 5,096 hours of sleep in a year for a Platypus. You subtract 6,604 and 5,096 together to get the answer, which is 1,508. Therefore we conclude that that the Giant Armadillo has 1,508 hours more hours of sleep than a Platypus in a Year.
Answer:
the diagonal is about 6.4 units
Step-by-step explanation:
i used pythagorean theorem to solve for the diagonal
a^2 + b^2 = c^2
5^2+ 4^2 = c^2
25+16=c^2
41= c^2
square root of 41 = c
6.4=c
c is the diagonal length
The area would be 324 yards square. Since the height is already found, you multiply 15 by 21 2/3 yards.
Hope this helped :)
