Answer:
y= 250( 1-0.21)^x
Step-by-step explanation:
This represents exponential decay
Answer:
63 yards
Step-by-step explanation:
Based on the description, you can make a rectangle with the sides 20 yards and 60 yards. You then draw a diagonal line (doesn't matter which one), and you use the pythagorean theorem (a^2+b^2=c^2). Thus, you get 20^2+60^2=60^2, so 400+3600=c^2, then \sqrt{4000}
Which gives the value of 63.24 rounding to 63 yards
Answer:
5 and 13
Step-by-step explanation:
1) If we call the larger number x and the smaller y we can write two equations.
y= x - 8 and x - 3=2y
2) we can substitute the x-8 in for the y in the second equation.
x-3=2(x-8)
3) by distributing and simplifying we find that x=13
4) To find y we need to plug x back into the first equation.
y=13-8
y=5
Answer:
Jennifer would save $0.25 per ounce.
Step-by-step explanation:
With the 32-ounce jar, the price per ounce is $0.25 per ounce. With the 8-ounce jar, the price is $0.50 per ounce. Jennifer would do better to buy the 32-ounce jar, as she would save $0.25 per ounce with that choice.
