The correct answer is C. I just took a test and answered B but that is not the correct answer. it is actually C
Answer:
-7
Step-by-step explanation:
f(3) = 2(3)+3 = 9
g(4) = 2^4 = 16
9 - 16 = -7
<em><u>Option E</u></em>
<em><u>The expression show how much pizza Marcus ate in total is:</u></em>
<em><u>Solution:</u></em>
Given that,
Marcus ate half of a pizza on Monday night
He then ate one third of the remaining pizza on Tuesday
Therefore,
Remaining is given as:
He then ate one third of the remaining pizza on Tuesday
Therefore,
<em><u>Thus expressions show how much pizza Marcus ate in total is:</u></em>
Total = monday night + tuesday
Thus Option E is correct
Answer:
I will answer in a general way because the options are not given.
We know that the area of model A is smaller than the area of model B.
For model A, we have 72 shaded sections, out of 100.
Then the quotient of model A is:
72/100 = 0.72
For model B we have 10 sections, and x shaded ones.
Because model B is greater than model A, we know that:
x/10 should be larger than 72/100
then we have the inequality:
x/10 > 0.72
x > 0.72*10
x > 7.2
And we can not have more than 10 shaded sections (because there is a total of 10 sections) then:
10 ≥ x > 7.2
Then x can be any whole number in that interval.
the possible values of x are:
x = 8
x = 9
x = 10
