We know that
Put
So,
Also, as per Newton's second law,
Put
So,
We know that the lift force is the sum of the gravitational force and the force of motion.
Answer:
Molly's
Step-by-step explanation:
The recipe with a stronger lemon flavor will have a greater ratio of lemon juice to water.
To find the ratio, divide the number of cups of lemon juice by the cups of water for each recipe:
Erica's recipe:
1/3
= 0.33
Molly's:
3/8
= 0.375
Since 0.375 is bigger than 0.33, this means Molly's recipe has a greater ratio of lemon juice to water.
So, Molly's recipe will have a stronger lemon flavor.
Answer:
12
Step-by-step explanation:
There are many ways to approach this problem. I like a method that uses the least amount of computation. We could figure how much Wendy makes on a bag of chips, the additional amount Wendy wants to make, then divide the latter by the former to find the number of additional bags to sell.
We could use a proportion to figure the number of bags corresponding to $126 in earnings, then subtract the 72 bags already sold. Essentially, we will do this, but without the intermediate numbers.
__
The additional fraction of 72 bags will be ...
(126/108) -1 = 18/108 = 1/6
Then Wendy must sell an additional ...
(1/6)×(72 bags) = 12 bags
to increase her earnings to $126.
Answer:426
Step-by-step explanation: multiply two numbers then multiply it by two
5*12=60*2=122
5*9=45*2=90
12*9=108*2=108
add and u get 426
