Answer 1

Answer:

n < - 0.6

Step-by-step explanation:

- 4n + 0.3 > 2.7

- 4n > 2.7 - 0.3

- 4n > 2.4

[tex]\frac{-4n}{-4}[/tex] < [tex]\frac{2.4}{-4}[/tex]

n < - 0.6

n ∈ ( - ∞ , - 0.6 )

Answer 2

-4n+0.3 > 2.7

-4n+0.3 -3.2 > 2.7-3.2 (Subtract 0.3 from both sides)

-4n > 2.7 - 0.3

-4n > 2.4

-4n/-4 > 2.4/-4 (Divide both sides by -4)

n > -0.6

James has read 108 pages of a book in 3 days. At that rate, how many days would it take him to read 576 pages of the book?

Answers

Answer:

16 days

Step-by-step explanation:

If 108 is divided by 3 is equal to 36 so in one day james can read 36 pages

So 576 divided by 36 is 16

Answer:

16 days

Step-by-step explanation:

This is because 1 day = 36 pages

16 days = 576

1. Given

total number of pages = 576

read number of pages = 108

read number of pages in days = 3

2. Unknown

days to read 576 pages = ?

3. Equation

108/3 = 36

576/36 = 16

4. Check

16*36 = 576 = 576

Correct!

Answer:

x = 20

Step-by-step explanation:

these are alternate interior angles, which means they're equal.

x + 40 = 3x

subtract x from both sides

40 = 2x

divide both sides by 2

20 = x

You are adding orange juice to a 10-liter capacity jar. The equation 3x – 2y = -5 relates the amount of juice y, in liters, with the number of minutes, x, you add juice. How much juice was in the jar to start?
At what rate is the jar filled?

Answers

Answer: 5/2 liters (or 2.5 liters) of juice were in the jar to start.

The jar was filled at a rate of 5 minutes.

Step-by-step explanation: Firstly, rearrange the equation so that y = mx + b. If you move the x over, you get -2y = -3x -5. To get rid of the -2 in front of the y, divide both sides by -2. Then you get y = 3/2x + 5/2.

The amount of juice in the jar initially is b, also known as the y-intercept.

If you look at the equation, you see that 5/2 is our y-intercept which means the jar initially had 5/2 liters of juice at the start (this is the same as 2.5 liters because 5 divided by 2 is 2.5).

To find the rate at which the jar was filled, you need to solve for x. Plug in the 10 liters for the y and solve.

y = 3/2x + 5/2

10 = 3/2x + 5/2

Now, subtract 5/2 from both sides.

7.5 = 3/2x

Divided both sides by 3/2 to get x alone, which will give you the number of minutes in which the jar was filled.

5 = x

The jar was filled at a rate of 5 minutes.

Mrs. Lovejoy makes flower arrangements. She has 36 red carnations, 60 white carnations, and 72 pink carnations. Each arrangement must have the same number of each color. What is the greatest number of arrangements she can make if she uses every carnation?

Answers

Answer:

12 arrangements

Step-by-step explanation:

We solve this question using the Greatest Common Factor method.

We are told that:

She has 36 red carnations, 60 white carnations, and 72 pink carnations.

The same number of each item should be in each basket.

The greatest number of baskets is calculated as follows:

Step 1

The factors of 36 are: 1, 2, 3, 4, 6, 9, 12, 18, 36

The factors of 60 are: 1, 2, 3, 4, 5, 6, 10, 12, 15, 20, 30, 60

The factors of 72 are: 1, 2, 3, 4, 6, 8, 9, 12, 18, 24, 36, 72

Step 2

We Identify the number that is greatest and common amongst 36,60, and 72

This is 12.

Then the greatest common factor is 12

Therefore, the greatest number of arrangements she can make if she uses every carnation is 12 arrangements

A music producer is making a list of vocalists needed to record an album. For each day of recording, a different number of vocalists are needed. The first day, six vocalists are needed. Each day after that, the number of vocalists needed doubles. The producer must pay by the day for each vocalist. To find the total price, the producer needs to know how many vocalists sang in total at the end of the 10th day. Use a series to find the sum after the 10th day. 114 150 3,066 6,138

Answers

Answer:

6,138

Step-by-step explanation:

Given the following:

Vocalist needed :

First day (a) = 6

For subsequent days : number doubles

Using the relation. :

Sn = a(r^n -1)/(r -1)

Where a = first term = 6

r = common ratio = r3/r2 = r4/r3

Since number doubles after each consecutive day, then ; r = 2, n = 10

Sn = 6(2^10 -1)/(2 -1)

Sn = 6(1024 - 1) / 1

Sn = 6144 - 6

Sn = 6138

How to find factor of polynomial using X method?

The factor of a polynomial is the terms in linear form, which are when multiplied together, give the original polynomial equation as result. X-method is the method to find the factors of the polynomial equation.

The polynomial equation is given as,

[tex]x^2 +16x +48[/tex]

An x-method chart shows the product a c at the top of x and b at the bottom of x for the standard polynomial equation. The standard polynomial equation can be given as,

[tex]ax^2+bx+c[/tex]

Comparing the given equation with standard polynomial equation, we get,

[tex]a=1\\b=16\\c=48[/tex]

The x method chart is attached below for the given equation.

The terms 16 x can be divided into the two terms 12x and 4x using the X-method. Thus the equation will become,

[tex]x^2 +12x +4x+ 48[/tex]

Thus, the equivalent four-term polynomial which can be created using the x method is,

Step-by-step explanation:

A = (-2/3, 0)

B = (-1/6, 0)

C = (1/2, 0)

D = (4/3, 0)

Step-by-step explanation:

the interval between 0 and 1 shows us, that on that scale the distance between 2 full numbers is split into 6 parts.

so, every little marker represents 1/6.

A goes 4 markers below 0 (left of 0) and is -4/6 = -2/3.

B goes 1 marker below 0 and is -1/6.

C goes 3 markers above 0 (right of 0) and is 3/6 = 1/2.

D goes 2 markers above 1 and is

1 + 2/6 = 6/6 + 2/6 = 8/6 = 4/3 = 1 1/3

Answers

The central angle (127 degrees) is the angle at point K

The measures of JL and JML are 127 and 233 degrees, respectively

How to determine the measures of angles JL and JML?

From the complete question, we have:

JL = 127 degrees.

The sum of angles at a point is 360 degrees

So, we have:

JML + 127 = 360

Subtract 127 from both sides

JML = 233

Hence, the measures of JL and JML are 127 and 233 degrees, respectively
