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.

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.

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.

Answer:

40

Step-by-step explanation:

4+5=9

9x(10/9)=10

10x4=40

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%

Higher than 98 is greater than 2 standard deviations, and that is 2.28%

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

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

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]

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.
