Answer:
16 is double 8, so just double the price: 2.64 x 2= $5.28
then, subtract to find the dufference: 5.28 - 4.48= $.80
then, divide that by the oz:
.80/16= 5 cents per ounce
Answer:
c
Step-by-step explanation:
The answer is B, kilometers.
—Evidence—
•] it is assumed that there are 6 stadia in a kilometer (km), meaning that Eratosthenes found the Earth's circumference to be about 42,000 km
First, find the function that represents x and y.
x is the number of 8 oz jars
y is the number of 16 oz jars
function: 8x + 16y = 240
x-intercept: y = 0 => 8x = 240 => x = 30 => (30,0)
y-intercept: x = 0 => 16y = 240 => y = 15 => (0, 15)
Answer: (0,15) and (30,0)
On the graph, it shows that the shortest meeting has lasted for 1/4 of an hour. An hour has 60 mins, you know it the shortest will be 15 minutes.
If its for any other number that you do not know, you can list as a proportion:
1/4 = x/60 (1 and x are on the top of the fractions)
Cross multiply: 1 * 60 = 60
Then divide by the number on the opposite corner of x: 60/4
x = 15
