Answer:

The subset of rational numbers

Step-by-step explanation:

Rational numbers are numbers that can be expressed in the form a/b where ad b are integers. The number [tex]1.\overline5[/tex] is a number with a recurring decimal of 5 and every recurring decimal can be expressed in the form a/b where a and b are both integers therefore, every number with recurring decimal is a rational number.

In the question,  [tex]1.\overline5[/tex]  can be written as follows;

[tex]1.\overline5 = \dfrac{14}{9}[/tex] or [tex]1.\overline5 = 1\dfrac{5}{9}[/tex].

Be that unknown number X

Then we can write the following expression:

X + 4.7 = 8.1

Answer:

y=15+-6x

Step-by-step explanation:

y = -6x + 15

Reorder the terms:

y = 15 + -6x

Solving

y = 15 + -6x

Solving for variable 'y'.

Move all terms containing y to the left, all other terms to the right.

Simplifying

y = 15 + -6x

Step-by-step explanation:

[tex]6x - 15 = y \\ 6x = y + 15 \\ \frac{6x}{6} = \frac{y + 15}{6} \\ x = \frac{y + 15}{6} \\ x = \frac{y}{6} + \frac{5}{2} [/tex]

Answer:

The exact answer is 10 pi km

Step-by-step explanation:

The circumference of a circle is given by

C = pi * d

C = pi * 10

C = 10 pi

The exact answer is 10 pi km

Answer:

circumference formula=2pi r

finding radius using diameter

r=d/2

r=10km/2

r=5km

now putting the value of r in circumference formula

c=2 pi r

c=2×3.14×5km

c=31.4km

Answer:

see below

Step-by-step explanation:

1/12 - 5/6 = -9/12

We need to get a common denominator of 12

1/12 - 5/6*2/2 = -9 /12

1/12 - 10/12 = -9/12

Since the denominators are the same, we can subtract the numerators

1-10 = -9

-9/12 = - 9/12

We can simplify -9/12 by dividing the top and bottom by 3

-9/3 = -3

12 /3 = 4

-9/12 = -3/4

Answer:

see below

Step-by-step explanation:

1/12 - 5/6 = -9/12

1st, we need to identify the Least Common Multiplier of 12 and 6

in this case, the LCM is 12

for 5/6 = (5*2) / (6*2) = 10/12

2nd, adjust the fractions based on the LCM

= 1 / 12  -  10 / 12

= 1 - 10 / 12

= -9 / 12 ---- simplify   -3 / 4

Answer:

B

Step-by-step explanation:

The equation of a horizontal line is

y = c

where c is the value of the y- coordinates the line passes through.

The line passes through (- 3, 8 ) with y- coordinate of  8, thus

y = 8 ← equation of horizontal line

Answer: If I’m not mistaken, I’m pretty sure it’s the second choice.

Step-by-step explanation: From what I can tell, the other three are all similar to each other and the third choice seems to be the odd one out. I hope I was correct!

Answer:

The length of the frame is 17

Step-by-step explanation:

The computation of the length of the frame is shown below:

As we know that

The perimeter of a rectangle is

= 2 (length + width)

where,

let us assume the width be x

So, the length is x - 6

And, the perimeter is 80 yards

So, now put these values to the above formula

80 yards = 2 (x - 6+ x)

80 yards = 2 (2x - 6)

80 yards = 4x - 12

92 = 4x

x = 23

So, the length of the frame is

= 23 - 6

= 17

Answer:

X=7

Step-by-step explanation:

STEP 1: Simplify both sides of the equation

7x + -10 + 2x =39 + 2x

(7x + 2x) + (-10) = 2x + 39 (combine like terms)

9x -10 = 2x + 39

step 2: Subtract 2x from both sides

9x -10 - 2x = 2x + 39 - 2x

7x - 10 =39

Step 3: Add 10 to both sides.

7x - 10 + 10 = 39 + 10

7x = 49

Step 4: Divide both sides by 7.

7x/ 7 = 49/7   x=7

hope this helps!!

Answer:

Step-by-step explanation:

The standard equation of a given line is expressed as y = mx+c where m is the slope and c is the intercept.

given the function f(x)= 3x − 3, comparing this equation with the standard format, we will have;

mx = 3x

Divide through by x

mx/x = 3x/x

m = 3

Hence the slope of the function f(x)= 3x − 3 is 3.

For a function g(x) passing through the points (0, 2) and (1, 5), to determine the slope, we will use the formula for calculating slope expressed as;

m = Δy/Δx = y₂-y₁/x₂-x₁

From the coordinates, x₁ = 0, y₁ = 2, x₂ = 1, y₂ = 5

m = 5-2/1-0

m = 3/1 = 3

Hence the slope of g(x) passing through the points (0, 2) and (1, 5) is also 3.

This shows that both functions have the same slope.

Answer:

5x^2 + -3

Step-by-step explanation:

For this problem, we will simply simplify the expression by combining like terms.

(-3x^3 - 7x^5 - 3) + (5x^2 + 3x^3 + 7x^5)

= 7x^5 + -7x^5 + 3x^3 + -3x^3 + 5x^2 + -3

= 0 + 0 + 5x^2 + -3

= 5x^2 + -3

Thus, the simplified expression is 5x^2 + -3.

Answer:

The building to the left is taller.

Step-by-step explanation:

Building on right:

tan 40° = a/56

a = 56 tan 40° = 46.99

Building on left:

tan 50° = b/49

b = 49 tan 50° = 58.40

The building to the left is taller.

Answer:

8cm

Step-by-step explanation:

1. x = width

length = 2x - 4

(2x - 4)x = 96

2x ^ 2 - 4x - 96 = 0

x ^ 2 - 2x - 48 = 0

(x + 6)(x - 8) = 0

Since the width cannot be negative, the width would be 8cm.

Answer:
