Answer:
240
Step-by-step explanation:
Assign Variables:
(I will choose mine a little bit differently)
d = length of garden
d = 20 feet
w = width of garden
A = area of garden
Equations and Solution:
A=d%2Aw and perimeter given as 64 feet means 2d%2B2w=64.
We know what is the d value, so we want to solve for w.
-
2w=64-2d
w=32-d
w=32-20
highlight%28w=12%29 feet
-
FINDING AREA VALUE
A=d%2Aw
A=20%2A12
highlight%28A=240%29 square feet
Hope this helps
ANSWER: (A) y= 10/3
EXPLANATION:
Create an equation for the graph⇩
From looking at the graph, the lemon juice in ounces is 3 times less than the water in ounces. Using this, we can create the following equation with y standing for the lemon juice and x standing for the water.
Y= x/3
Since we are solving for the amount of water, we have to substitute x for 10⇩
Y= 10/3
Enjoy your answer!⇩
y=10/3 (A)
The sign in the exponent: positive->increases, negative->decreases. Think that a negative sign implies 1/exponential and you'll clearly see the reason.
Answer: Choice A
The second fraction should not have been multiplied by 9
This is because 1/9 already has the LCD in the denominator. LCD stands for lowest common denominator.
The first fraction 2/3 does not have 9 in the denominator, which is why they multiplied top and bottom by 3
2/3 = (2*3)/(3*3) = 6/9
After each fraction has the same denominator (9), you can add the numerators to place over the LCD like so
6/9 + 1/9 = (6+1)/9 = 7/9
This means,
2/3 + 1/9 = 6/9+1/9 = 7/9
