X - 3 > 7
x > 7 + 3
x > 10
answer x > 10
Answer:
D is the answer
Step-by-step explanation:
We want a mixture of low-fat and whole milk to equal 32ounces
Therefore, we know one equation is:
l + w = 32
That 32 ounce mixture should be 2% butter fat
So the amount of butter fat we want is
2% of 32 = 0.64 ounces
At the same time, this mixture contains low-fat and whole milk, which contain 1% and 3.25% butter fat respectively.
therefore, the butter fat in low-fat and whole milk is 0.01l and 0.0325w respectively.
The coefficients are just the percentages in decimal form
Due to the law of conservation of mass,
The addition of these two should yield the final amount of butter fat, meaning the other equation is:
0.01l + 0.0325w = 0.64
Answer:
Set membership x ∈ X means x is an element of the set X. (Non-membership is written x ∈ X.) Set inclusion X ⊆ Y means every element of X is an element of Y ; X is a subset of Y .

2b+1>5 I believe because 6b-1<-7 is wrong
The volume of a cylinder is =
V = π.R^(2).h
Let's to the first example:
R = 3cm
h = 32cm
Then,
1:
V = π.(3)^2.(32)
V = 288π.cm^3
This is correct.
Let's to the second example:
2:
R = 4cm
h = 12cm
Then,
V = π . (4)^2 . 12
V = 192 π cm^3
It is false.
___________
Let's to the 3 example:
R = Diameter / 2
R = 16 / 2
R = 8cm
And, h = 9cm
Then,
V = π . (8)^2 . 9
V = 576π cm^3
It is false
_____________
Let's to the 4 example:
R = 4cm
h = 18cm
Then,
V = π . (4)^2 . 18
V = 288π cm^3
This is correct
________________
Let's to the 5 and last example:
R = Diameter / 2
R = 12 / 2
R = 6 cm
h = 8cm
Then,
V = π . (6)^2 . 8
V = 288π
That's right too.
Then, The answers corrects to the your question are:
Example: 1 , 4 and 5
