Answer:

Anything between 4 and 14

Step-by-step explanation:

When two lengths of a triangle are added together, they must be greater than the third side. Therefore the unknown length cannot be equal to or less than 4 nor equal to or greater than 14.

Answer:

159°

Step-by-step explanation:

Angle 21° and <4 are supplementary angles!

21 + x = 180

x = 159°

Hope this helps!

The measure of angle ∠4 is 159.

The angles that are in the same position on a given two parallel lines intersected by a transversal line are called the corresponding angles.

Corresponding angles are always equal.

We can also have alternate angles which are always equal.

We can also have alternate interior and exterior angles which are equal.

The angles on the same side make upto 180 degrees

We have,

From the figure,

The angle opposite to 21° and ∠4  sum is 180.

This means,

Angles on the same side.

Now,

Opposite angles are equal.

So,

21 + ∠4 = 180

∠4 = 180 - 21

∠4 = 159

Thus,

The measure of angle ∠4 is 159.

Step-by-step explanation:

Put -5 in place of x

18(-5)-42 does not equal 7(-5)

-90-42 does not equal -35

-90-42=-132, not -35

The value x = -5 is a solution to the inequality 18x − 42 ≠ 7x.

The relation between two expressions that are not equal, employing a sign such as ≠ ‘not equal to’, > ‘greater than, or < ‘less than.

For showing x =-5 is a solution of the inequality 18x − 42 ≠ 7x put x =-5 in the solution if it satisfies the condition then it is a solution of the given inequality.

18x − 42 ≠ 7x

18 x ( -5 ) - 42 ≠ 7 x ( -5 )

-132 ≠ -35

The value x = -5 is satisfying the given inequality. Hence, x = -5 is a solution to the inequality 18x − 42 ≠ 7x.

Answer:

  30

Step-by-step explanation:

The ring operator signifies a composition of functions. The composition is evaluated right-to-left. That means the composition ...

  [tex](f\circ g)(x)[/tex]

should be interpreted to mean ...

  [tex]f(g(x))[/tex]

___

To evaluate f(g(6)), we first evaluate g(6):

  g(6) = 6² -5 = 31

Then we evaluate the function f using that as its argument:

  f(31) = 31 -1 = 30

  f(g(x)) = 30

Step-by-step explanation:

Answer:

x = 10; y = 6

Step-by-step explanation:

Let's list the factors of 60 because the product of those numbers is 60.

The following possibilities of x and y are possible using (x × y = 60):

Let's check each possibilities using the equation (x - y = 4):

Thus, the values of x and y are 10 and 6 respectively.

Answer: 37

Step-by-step explanation:

            range = max - min

max = maximum value in a data set

min = minimum value in a data set

         Maximum value: 57

         Minimum value:   20

                       Range: 37

Answer:

37

Step-by-step explanation:

First of all, let's define what range is. The range is the highest value of a set of numbers minus the lowest value of the same set. In this case, your highest value is 57 and your lowest value is 20. The sum would be 57 - 20 which would equal 37 and that is your answer.

The equation in standard form of the line is given by:

[tex]\frac{8}{3}x + y = 15[/tex]

A linear function is modeled by:

y = mx + b

In which:

In this problem, the line is parallel to 8x + 3y =15, hence the slope is given by:

[tex]m = -\frac{8}{3}[/tex]

It passes through the point (6, -1), hence:

y = mx + b

[tex]-1 = -\frac{8}{3} \times 6 + b[/tex]

b = 15

Hence:

Answer:

32

Step-by-step explanation:

Since we know 8 = 1/4

We can convert the 1/4 into a percentage:

8 = 25%

To get to 100% which is the full club we have to multiply both sides by 4:

8×4 = 25% ×4

32 = 100%

So there are 32 people in the club.

A rectangle is a 2-dimensional shape having 4 sides. The width of the rectangle is 5x^2 + 4x - 6

A rectangle is a 2-dimensional shape having 4 sides

The formula for calculating the area of the rectangle is given as:

A = lw

Given the following

Area = 5x^3+19x^2+6x-18
Length = x + 3

Using the synthetic division:

           5x^2 + 4x - 6

x + 3 |  5x^3+19x^2+6x-18

           5x^3 + 15x^2

________________________

                     4x^2 + 6x

__________________________

                                -6x - 18

Answer:

Step-by-step explanation:

Area = length x width

area of files = 30 x 20 = 600 square feet

area of unmoved field = 16 x 26 = 416 square feet

area that was mowed = 600 - 416 = 184 square feet

answer: 184 square feet

Answer:

184 ft

Step-by-step explanation:

so, for this, the key is the smaller dimentions on the inside, they are the area of the smaller inner rectangle (416 ft) and the bigger dimentions on the outside, are for the entire rectangle including the mowed area (600 ft), but you dont know the exact value of the mowed area, so you would simply subtract the areas (600-416=184) and that number, 184, is the area of the mowed area that you didnt know.
