Answer:
a. c = 2030,
b. n = 1.42,
c. x = 2.875,
d. k = 140
Step-by-step explanation:
a ) 8120 = 4c,
c = 8120 / 4 = 2030
b ) 0.5n = 0.71,
n = 0.71 / 0.5 = 1.42
c ) 8x = 23,
x = 23 / 8 = 2.875
d ) 7 : 6 = k : 120
Here we want to convert this ratio into fraction form,
7 / 6 = k / 120
And now we can cross - multiply to determine the value of k,
6k = 7(120) = 840,
k = 840 / 6 = 140
We can check the value of k, by plugging it back into our ratio, and see if it reduces to 7 : 6,
140 : 120,
14 : 12,
7 : 6
Answer:
B
Step-by-step explanation:
Lets convert everything to gallons.
Alpha Mart:
1 quart = 0.25 gallons
1 * 0.25 = 0.25 gallons for $1
1 / 0.25 = 4 * 1 = $4 per gallon
Beta Mart:
1 gallon for $3
Gamma Mart:
1 pint = 0.125 gallons
0.125 gallons for $0.54
1 / 0.125 = 8 * 0.54 = $4.32 per gallon
Delta Mart:
1 quart = 0.25 gallons
2 * 0.25 = 0.5 gallons for $1.86
1 / 0.5 = 2 * 1.86 = $3.72 per gallon.
As we can see from all the unit prices, Beta Mart sells milk for the cheapest price.
Best of Luck!
Answer:
If he has 45% of his cheak remaining we already have the remaining so we just to turn it into a fraction
First we put it over 100
<u>45</u>
100
Then we reduce it to the lowest terms
which would be
9/20
