Find x
To solve for x, we make use of the following equivalent ratio
[tex]4 : 6 = x : 12[/tex]
Convert to fractions
[tex]\frac{4}{6} = \frac{x}{12}[/tex]
Multiply both sides by 12
[tex]12 * \frac{4}{6} = \frac{x}{12} * 12[/tex]
[tex]12 * \frac{4}{6} = x[/tex]
[tex]x = 12 * \frac{4}{6}[/tex]
[tex]x = \frac{12 * 4}{6}[/tex]
[tex]x = \frac{48}{6}[/tex]
[tex]x = 8[/tex]

difference from mean/14 is z-score
z<=-3 for a score of 28 (28-70)/14. This would be about 0.0013 or 0.13%
z<=-2 for a score of 42, and that is about 0.0228
z<=-1 for a score of 56 and +1 for a score of 84. That is about 68%
between 70 and 84 is a z-score between 0 and 1, and that is about 34%

Lila decided to make more baked goods for the bake sale. She used 1/8 less flour to make bread to make cookies. She used 1/4 more flour to make cookies than to make brownies. If she used 1/2 of flour to make the bread, how much flour did she use to make the brownies. Explain your answer.
Answer:
3/7 cup
Step-by-step explanation:
Ignore the units for the time being. Just to give it units, you could call it cups. This question is really about ratios.
Let the cookies = x
Then the bread = x - 1/8 x = 7/8x
The brownies = cookies - 1/4 cookies
The brownies = 3/4 cookies = 3/4 x
==============
Now start again.
The bread uses 1/2 cup.
That translates into 1/2 = 7/8 x
x = 1/2 // 7/8 = 4/7 cup for the cookies (4/7 is larger than 1/2)
Whatever the cookies are, the brownies take 3/4 as much
4/7 * 3/4 = 12/28 = 3/7
The answer should be 3/7 of a cup.
9514 1404 393
Answer:
3/8 lb
Step-by-step explanation:
If all units are pounds, then we have ...
bread = cookies - 1/8 lb
cookies = brownies + 1/4 lb
bread = 1/2 lb
Using the last value in the first equation, we find ...
1/2 lb = cookies - 1/8 lb
cookies = 5/8 lb . . . . . . . add 1/8 lb to both sides
Using this in the second equation gives ...
5/8 lb = brownies + 1/4 lb
3/8 lb = brownies . . . . . subtract 1/4 lb from both sides
__
Lila used 3/8 lb of flour to make the brownies.

HELP PLS MY TEACHER WANTS TO KNOW THE ANSWER!!!
Missy is getting married and addressing invitations. She has at least 140 envelopes and has addressed 26 of them. Write an inequality that describes how many more invitations must be addressed.
Answer:
e ≥ 114 where e is the number of envelopes
Step-by-step explanation:
Let the number of envelopes for invitations to address be --------e
Hence the inequality of the number of envelopes is : e ≥ 140
Number of addressed envelopes is : 26
Remaining number of envelopes to address is : 140 -26 = 114 or more
The inequality that describes how many more invitations must be addressed is ;
e ≥ 114

What is the greatest common factor of 39, 42, and 33?
HELP PLSSS!!!
The greatest common factor (GCF) of 33 and 39 is 3. We will now calculate the prime factors of 33 and 39, then find the greatest common factor (greatest common divisor (gcd)) of the numbers by matching the biggest common factor of 33 and 39.
here you go
Answer: The greatest common factor of 39, 42, and 33 is 3
Step-by-step explanation:
We first find the factors of the numbers
39=1x39, 3x13 (1,3,13,39)
42=1x42, 2x21, 3x14, 6x7(1,2,3,6,7, 42)
33=1x33, 3x11(1,3,11.33)
The common factors are the factors that appear in the three numbers which are 1 and 3
The greatest common factor therefore is 3

Which statement describes the sequence defined by an
n3 +3?
n2-60
O The sequence diverges.
O The sequence converges to a limit of 0.
O The sequence converges to a limit of infinity
O The sequence converges to a limit of - infinity
Answer:
C
Step-by-step explanation:
To find the statement that describes the sequence, we find it's limit as n goes to infinity.
Doing this, as we get that the limit goes to infinity, we get that the sequence diverges.
Sequence:
[tex]a_n = \frac{n^3 + 3n}{n^2 - 6n}[/tex]
Limit as n goes to infinity:
Limit of n going to infinity, so we consider just the terms with the highest exponent in the numerator and in the denominator.
[tex]\lim_{n \rightarrow \infty} a_n = \lim_{n \rightarrow \infty} \frac{n^3 + 3n}{n^2 - 6n} = \lim_{n \rightarrow \infty} \frac{n^3}{3n^2} = \lim_{n \rightarrow \infty} \frac{n}{3} = \frac{\infty}{3} = \infty[/tex]
Thus, the correct answer is that the sequence diverges.

Describe the end behavior of f(x)=-2x^3 using the leading coefficient and degree, and state the domain and range
Answer:
See explanation for end behavior below
Domain = All Real numbers
Range = All Real numbers
Step-by-step explanation:
This is a typical power function of order 3, and since its coefficient is a negative one (-2), its end behavior is:
As x becomes more and more negative (moving towards the left of the horizontal axis, the values for y will become larger and larger (reaching very positive numbers on the y scale). As x becomes larger and larger (moving towards large values on the positive side of the horizontal axis, the related y values will become more and more negative.
The Domain of the function (the x-values for which the function is defined) consists of all Real numbers.
The same is true for the Range, since the y-values spread over all the real number line.
