Answer:8-oz jar
First, we have to find out what is the unit rate of the 2-oz jar. $1.50÷2 is $.75.
Second, we have to find the unit rate of the 4-oz jar. $2.92÷4=$73.
Third, we have to find the unit rate of the 8-oz jar. $5.68=$.71.
Fourth, we have to find the unit rate of the 16-oz jar. The division for this one may be tricky. From dividing $11.62 by 16, is stopped at the 3rd number I got from dividing. I got $.726. This is not a value of cents and the value can't go in the thousandths place. So, I rounded .726. I got $.73. So $11.62÷16=$.73.
Lastly, you have to compare the amounts.
The lowest amount or better buy, is $.71 or 8-oz jar.
Answer:
f(- 3) = 18
Step-by-step explanation:
To evaluate f(- 3) substitute x = - 3 into f(x)
f(- 3) = (- 3)² - 2(- 3) + 3 = 9 + 6 + 3 = 18
Answer:
Step-by-step explanation:
The graph of g(x), if translated upward by 1 unit, becomes the graph of h(x) = g(x) + 1.
Answer:
Step-by-step explanation:
-4(-6x + 5) = 4
Divide both sides of the equation by -4
-6x + 5 = -1
Subtract 5 from both sides of the equation
-6x = 4
Divide both sides of the equation by -6
x = 4/-6
Simplify
Hope this helps :)
Black keys : white keys
b : w = 36 : 52
b : w = 18 : 26 = 9 : 13
b : w = 9 : 13
Total ratio = 9 + 13 = 22.
It means for every 9 black keys you have 13 white keys.
It also means for the piano the fraction of black keys is 9/22 of the entire piano
It also means for the piano the fraction of white keys is 13/22 of the entire piano
