Answer:

[tex]x<\frac{16}{125}[/tex]

Step-by-step explanation:

First we will multiply everything by 10 to get rid of the decimals.

[tex]4.2x*10+5.6*10<7.2*10-8.3x*10\\42x+56<72-83x[/tex]

Subtract 56 from both sides:

[tex]42x+56-56<72-83x-56\\42x<-83x+16[/tex]

Add 83x to both sides:

[tex]42x+83x<-83x+16+83x\\125x<16[/tex]

Divide both sides by 125:

[tex]\frac{125x}{125}<\frac{16}{125}\\x<\frac{16}{125}[/tex]

Answer 7

Step-by-step explanation:

7 will be the greatest value.

Correct option is (D).

The definition of a set in mathematics is a group of things whose components are unchangeable and fixed. In other words, a set is accurately described as a group of data that does not pass from one person to another. The items can be written in any sequence, but they cannot be repeated in the set. Capital letters are used to denote the set.

Several other kinds of sets include the infinite set, the finite set, the equivalent set, the subset, the universal set, and the superset. Each kind of set has a different place in calculations. Sets are essentially used to represent large amounts of data and collections of data in everyday life. Thus, in this article, we'll learn about and talk about the universal set.

As per the given data:

The integer set is {7, -7, -3, 3}

For the greatest value, arranging the set in ascending order:

{-7, -3, 3, 7}

The greatest value will be 7.

Step-by-step explanation:

Area of a circle = [tex]\pi r^{2}[/tex]

Area  of a circle = 3.14 * 3 * 3  ( so i used pi as 3.14 ) then the radius is 3

Area of a circle  = 9.42 * 3       ( first 3.14 times 3 is 9.42)

Area of a circle  = 28.26          ( 9.42 times 3 is 28.26)

Answer:

add them all and put them equal to 180 cause all interiors angles of a triangle adds up to 180.

Step-by-step explanation:

x^2+6x+68=180

x^2+6x-112=0

(x-8)(x+14)

x=8

x^2+1=65

2x+24=40

4x+43=75

hence x^2+1 is your answer

Answer:

Option (B)

Step-by-step explanation:

Length of the rope Mr Hernandez has = 41 feet

He wants to enclose an area in the shape of a pentagon.

Therefore, minimum length of the rope required = perimeter of the pen

Perimeter of the pentagonal pen = Sum of the measures of all five sides of the pen

Perimeter = x + (7 - 5x) + (3x - 2) + (3x + 4) + (5 - 3x)

                = (-x + 14)

Now the length of the rope should be more than and equal to the perimeter of the pen to cover.

41 ≥ (-x + 14)

Or

-x + 14 ≤ 41

Therefore, Option (B) will be the answer.

Answer:

28 = 2 x - 2

Step-by-step explanation:

Step-by-step explanation:

To find the mean, you add all the numbers and divide by how many there are.

In this case, you add -54,-32,-70,-25,-65, and -42. Then you divide by 6 because there are 6 numbers.

When you add them all, you get -288.

Now divide.

-288/6=-48

Hope it helps!

Answer:

-48

so you add all the numbers together, which will give you -288

there are 6 terms, so you divide -288 by 6

gives you your answer of -48

Answer:

The first answer choice.

Answer choice A.

Step-by-step explanation:

The domain of a function would be the set of all possible x-values of that function.

Since we are looking for the domain, the set of the possible x-values, we can eliminate any answer choices that are a set of y-values. B and D are eliminated.

From what we can see in the table, the possible x-values of the function are -6, -1, 0 and 3. Although C does include these values in the set, it also includes many other values. As we can see, answer choice A includes the x-values given in the table and only those values. Therefore, answer choice A is the correct answer.

I hope you find my answer and explanation helpful. Happy studying.

Step-by-step explanation:

Got 100% on edge.

Answer:

(200+1,500) - 500 = 1,200 ft

Step-by-step explanation:

the hiker started at 200 ft then went 1500 more feet. (add it up) Then, she descends (goes down) 500 feet. So let's subtract 500 feet from the sum of 200 and 1500. ( (200+1500 equals 1700, then subtract 500 which will be 1200.) ) So, she is 1200 feet above sea level during the 10 minute break.

Answer:

243

Step-by-step explanation:

1. 1/3 * 3 = 1

2. 1 * 3 = 3'

3. 3*3 = 9

4. 9*3= 27

5. 27*3 = 81

6. 81*3 = 243

7. 243

Hope this helps!

The required 7th term in the given geometric sequence would be 243.

The geometric series defined as a series represents the sum of the terms in a finite or infinite geometric sequence. The successive terms in this series share a common ratio.

The sequence given in the question follows as:

1/3, 1, 3, 9, . . .

This sequence follows the pattern of a geometric progression, where each term is obtained by multiplying the previous term by a fixed number, called the common ratio.

The common ratio for this sequence is 3.

To find the nth term in a geometric progression, you can use the formula:

aₙ = arⁿ⁻¹

Where a is the first term, r is the common ratio

Plugging in the values for this sequence, we have:

[tex]a_7 = 1/3 \times 3^(7-1) = 1/3 \times 3^6[/tex]

= 1/3 x 729 = 729/3 = 243

Therefore, the 7th term in the sequence is 243.
