let x be the flour
now
or,(21/2)+x=42/3
or,(21+2x)/2=42/3
or, 3(21+2x)=42×2
or, 63+6x=84
or,6x=84-63
or, 6x =21
or, x=21/6
thus she need 21/6 cups of flour
Answer:
The ratio is 11:8
Step-by-step explanation:
There's 11 trees in Jeans yard hence the first number of the ratio (11)
While Anita has 8, hence the second number in the ratio (8)
Therefore the ration of Jean's trees to Anita's is 11:8
Answer:
Growth factor is 1.2
Growth rate is 0.2
Step-by-step explanation:
Generally, we can have an exponential function as:
y = a(1 + r)^x
Where a is the initial value (y value when x = 0, which is 10)
r is the growth rate
at x = 2
14.4 = 10(1 + r)^2 •••••(i)
at x = 1
12 = 10(1 + r)^1 •••••(ii)
Divide i by ii
14.4/12 = 1 + r
1.2 = 1 + r
r = 1.2-1
r = 0.2
1 + r = 0.2 + 1 = 1.2
Answer:
B. 2 units to the right and 2 units up
Step-by-step explanation:
Step-by-step explanation: Well we would know that the original soup is one gallon water and one gallon broth because that is 2 gallons 50% to 50%.
Then to decrease the amount of broth by 10%, we would accomplish this by first turning the original gallons into quarts so we would have 4 quarts broth and 4 quarts water. We need to get a total of ten quarts SO........ we know that we need to add 2 MORE quarts of WATER.
Finally when we add all the quarts together we get 10 total with 6 water and 4 broth which totals to 60% water and 40% broth.
FINAL ANSWER: 2 QUARTS WATER
