Answer:

The fraction of the flour Mrs. Mannng will use for her chocolate chip cookies is 4/9

Step-by-step explanation:

Fraction of Portion

Suppose we have a number n and another number m such as m>n. The portion or fraction of size n of m is given by the quotient n/m.

For example, 3 pieces of cake out of a total of 6 make them a fraction of 3/6 = 1/2 of the whole cake, i.e. half of the total available.

Mrs. Manning needs 1/3 cup of flour to make cookies for the bake sale. She actually has 3/4 cups of flour. Calculate the fraction of needed against the available flour:

[tex]\displaystyle \frac{\frac{1}{3}}{\frac{3}{4}}[/tex]

The division can be easier performed by multiplying by the reciprocal of the denominator:

[tex]\displaystyle \frac{1}{3}\cdot \frac{4}{3}=\frac{1*4}{3*3}[/tex]

[tex]\displaystyle =\frac{4}{9}[/tex]

The fraction of the flour Mrs. Mannng will use for her chocolate chip cookies is 4/9

Answer:

30,000 miles

Step-by-step explanation:

This is the answer because:

1) There are 36 months in 3 years

2) Divide 36 with 6 because we know this person drives 5,000 miles in 6 months

36/6 = 6

3) Finally, multiply 5,000 and 6 which is 30,000

5,000 x 6 = 30,000

Therefore, the answer is 30,000 miles

Hope this helps! :D

A person drives 5,000 miles in 6 months. So, 30,000 miles will that person drive in 3 years.

A person drives 5,000 miles in 6 months

To determine How many miles will that person drive in 3 years.

First we convert 3 years into month.

1 year = 12 months

3 years = 12 * 3 = 36 months

Now, lets consider

x miles will that person drive in 3 years

6 months = 5,000 miles

36 months = x miles

x = 5,000/6 * 36 = 30,000

Therefore, 30,000 miles will that person drive in 3 years.

The common difference of this Sequence is 12.

In mathematics, a sequence refers to an ordered list of numbers. When working with sequences, there are various concepts and formulas that are used to calculate different aspects of the sequence. One such concept is the common difference. Let's explore what the common difference is and how to calculate it.
What is the common difference?
The common difference in a sequence refers to the difference between any two consecutive terms in the sequence. For example, in the sequence 2, 4, 6, 8, 10, the common difference is 2. We get this value by subtracting the second term (4) from the first term (2) and so on.
How to find the common difference of a sequence?
To find the common difference of a sequence, you need to know at least two terms of the sequence. You can then subtract one term from the other to calculate the common difference.
Let's apply this to the given sequence, which has a first term of 5 and a fifth term of 17. To find the common difference, we can subtract the first term from the fifth term as follows:
17 - 5 = 12
Therefore, the common difference of this sequence is 12.

You can solve with many ways but I'll do this one instead. Move 12 to the left side and change from positive to negative.

[tex]2x^2-2x-12=0\\[/tex]

Then divide by 2 whole equation.

[tex]\frac{2x^2-2x-12}{2}=\frac{0}{2}[/tex]

Simplify, as we get  [tex]x^2-x-6=0[/tex]

We can either use Quadratic Formula or Factoring the Polynomials. It depends but since the polynomial aren't that hard to factor because it doesn't have that many numbers in value. So using factoring will be faster.

From [tex]x^2-x-6=0[/tex] we can factor as -

[tex](x-3)(x+2)=0\\x-3 =0, x+2=0\\x=3, x=-2\\(x=3,-2)#[/tex]

Thus, the value of x is 3 or -2. So x = 3, -2 is the answer.

Note that we can also use Quadratic Formula to solve the equation, however that will take longer than factoring then solve the equation.

Follows are the solution to this question:

Step-by-step explanation:

Given that:

n=1000  

Where the data is distorted and the bad outlier is just axed,when we transform scores of its distribution form into z-score, that become negative or skewed to the left.  If n=1000 doesn't have normal skewed knowledge, then:  

The data range is between 1 to 7

[tex]\to 1 \ to \ 7 = 6 \sigma \\\\\to \sigma =\frac{7-1}{6} \\\\\to \sigma = \frac{6}{6}\\\\\to \sigma = 1\\\\\mu = 4\\[/tex]

In point (1):

The score that matches:  

[tex]\to Z=-2 \ \ \ \mu -26 \\\\ \to 4-2 =2\\\\ \to Z_{score} =2[/tex]

In point (2):

Its value of Z= 0.5 is [tex]\mu \ \ to \ \ 5 \ \ \sigma[/tex]

Answer: D)[tex]\sqrt{3}[/tex]

Step-by-step explanation:

cot(θ) = cos(θ) ÷ sin(θ)

cot(30) = [tex]\frac{\sqrt{3} }{2}[/tex] ÷  [tex]\frac{1}{2}[/tex]

cot(30) = [tex]\sqrt{3}[/tex]

The value of cot30 is √3 if sin30 = 1/2 and cos30 = √3/2 option (D) is correct.

Trigonometry is a branch of mathematics that deals with the relationship between sides and angles of a right-angle triangle.

We have:

sin30 = 1/2

cos30 = √3/2

As we know,

cotA = cosA/sinA

A = 30 degrees

cot30 = cos30/sin30

cot30 = (√3/2)/(1/2)

cot30 = √3

Thus, the value of cot30 is √3 if sin30 = 1/2 and cos30 = √3/2 option (D) is correct.

(3x + 2)(x-4)

Step-by-step explanation:

3x² - 10x - 8 = 0

(splitting the middle term)

3x² -12x + 2x -8 = 0

3x(x-4) + 2(x-4) = 0

(3x + 2)(x-4) = 0

(3x + 2)(x-4) is the correct answer (option a)

Lucia biked approximately 12 7/10 miles per hour.

To find the number of miles Lucia biked per hour, we need to divide the total distance she biked by the total time taken.

Lucia biked a total distance of 50 4/5 miles in 4 hours.

To divide a mixed number by a whole number, we first convert the mixed number into an improper fraction.

50 4/5 = (50 * 5 + 4) / 5 = 254/5

Now, we can divide the distance by the time:

(254/5) miles / 4 hours = (254/5) / 4

To divide a fraction by a whole number, we multiply the fraction by the reciprocal of the whole number.

(254/5) / 4 = (254/5) * (1/4) = 254/20 = 12 14/20 = 12 7/10

Therefore, Lucia biked approximately 12 7/10 miles per hour.
