Divide the amount left by the percentage left:
they sold 35%, so there is 65% remaining.
280 / 0.65 = 430.769
Round to 431
Now check:
431 x 0.35 = 150.85
Round to 151
431 - 151 = 280 left.
They originally had 431 peaches.
Answer:
f(x) = -22.45x^2 + 92.38x + 1.86
Because the points on the scatter plot show an increase in concentration from 0 hours through 2 hours and a decrease from 2 hours through 4 hours, the relationship shown is best modeled using a quadratic function.
Let's look closely at the two quadratic function choices to determine the key features of their graphs.
Because the coefficient of its x^2 -term is negative, the graph of f(x) = -22.45x^2 + 92.38 + 1.86 will be concave down and have a maximum value.
Because the coefficient of its x^2 -term is positive, the graph of f(x) = 22.45x^2 + 92.38 + 1.86 will be concave up and have a minimum value.
Because the scatter plot shown has a concave down trend, the function that best describes the relationship shown is:
f(x) = -22.45x^2 + 92.38 + 1.86

Where is the Image I might can Help
Answer:
a) will definitely be an odd number
Step-by-step explanation:
4^n is always even (when you multiply even and even number, the product is always even)
when you add one to even number, the sum is always odd
so 4^n +1 is odd.
A- 405 miles : x or 405 miles : 15 gallons.
B. Y÷ X
Y= 2, 500
X=15
2, 500÷15=166.670 (rounded to the nearest hundredth)
