Is -6/11 a irrational number?
Answer:
No
Step-by-step explanation:
One way to tell if a number is rational is if it can be written as a fraction. Anything that can be written as a fraction of two integers is rational.
-6/11 is a fraction with integer numerators and denominators.
Therefore it is rational.

Mary spends her Saturday mornings buying groceries, helping her children with homework, cooking, and
working on her weekend assignment. She does not always do these tasks in the same order. In how many
possible ways can she do her tasks?
Answer:
I think in 2 or 3 process. But I am not sure
will mark brainliest!!
Answer:
In March she sent 752 texts
In April she sent 617
Step-by-step explanation:
The phone bill is 35 + additional texts, so in both bills the value relative to the texts are:
72.6 - 35 = 37.6 for March
65.85 - 35 = 30.85 for April
Each texts costs 0.05, so if we divide the value relative to the texts by 0.05 we will have the number of texts she sent:
37.6/0.05 = 752 texts
30.85/0.05 = 617 texts

Solve each inequality, and then drag the correct solution graph to the inequality.
The correct solution graph to the inequalities are
[tex]4(9x-18)>3(8x+12)[/tex] → C
[tex]-\frac{1}{3}(12x+6) \geq -2x +14[/tex] → A
[tex]1.6(x+8)\geq 38.4[/tex] → B
(NOTE: The graphs are labelled A, B and C from left to right)
For the first inequality,
[tex]4(9x-18)>3(8x+12)[/tex]
First, clear the brackets,
[tex]36x-72>24x+36[/tex]
Then, collect like terms
[tex]36x-24x>36+72\\12x >108[/tex]
Now divide both sides by 12
[tex]\frac{12x}{12} > \frac{108}{12}[/tex]
∴ [tex]x > 9[/tex]
For the second inequality
[tex]-\frac{1}{3}(12x+6) \geq -2x +14[/tex]
First, clear the fraction by multiplying both sides by 3
[tex]3 \times[-\frac{1}{3}(12x+6)] \geq3 \times( -2x +14)[/tex]
[tex]-1(12x+6) \geq -6x +42[/tex]
Now, open the bracket
[tex]-12x-6 \geq -6x +42[/tex]
Collect like terms
[tex]-6 -42\geq -6x +12x[/tex]
[tex]-48\geq 6x[/tex]
Divide both sides by 6
[tex]\frac{-48}{6} \geq \frac{6x}{6}[/tex]
[tex]-8\geq x[/tex]
∴ [tex]x\leq -8[/tex]
For the third inequality,
[tex]1.6(x+8)\geq 38.4[/tex]
First, clear the brackets
[tex]1.6x + 12.8\geq 38.4[/tex]
Collect likes terms
[tex]1.6x \geq 38.4-12.8[/tex]
[tex]1.6x \geq 25.6[/tex]
Divide both sides by 1.6
[tex]\frac{1.6x}{1.6}\geq \frac{25.6}{1.6}[/tex]
∴ [tex]x \geq 16[/tex]
Let the graphs be A, B and C from left to right
The first graph (A) shows [tex]x\leq -8[/tex] and this matches the 2nd inequality
The second graph (B) shows [tex]x \geq 16[/tex] and this matches the 3rd inequality
The third graph (C) shows [tex]x > 9[/tex] and this matches the 1st inequality
Hence, the correct solution graph to the inequalities are
[tex]4(9x-18)>3(8x+12)[/tex] → C
[tex]-\frac{1}{3}(12x+6) \geq -2x +14[/tex] → A
[tex]1.6(x+8)\geq 38.4[/tex] → B

Answer:
4(9x − 18) > 3(8x + 12) = x > 9
(12x + 6) ≥ -2x + 14 = x ≤ -8
1.6(x + 8) ≥ 38.4 = x ≥ 16
Just follow the numbers with the dotted thing and see the numbers I underlined.
Step-by-step explanation:
Use the properties of inequality and real numbers to solve each inequality.
4(9x − 18) > 3(8x + 12)
36x − 72 > 24x + 36
12x − 72 > 36
12x > 108
x > 9
The graph has an open circle at 9, and moves toward the right on the number line.
(12x + 6) ≥ -2x + 14
12x + 6 ≤ 6x − 42
6x + 6 ≤ -42
6x ≤ -48
x ≤ -8
The graph has a closed circle at -8, and moves toward the left on the number line.
1.6(x + 8) ≥ 38.4
x + 8 ≥ 24
x ≥ 16
The graph has a closed circle at 16, and moves toward the right on the number line.

Answer:
the answer is option 1
Step-by-step explanation:
the negative angle => a quarter round angle (clockwise) = ¼ x ( -360°) = -90°
and
the positive angle => a full round angle + 270° = (360°)+270°
= 630°
Answer:
correct answer is -90 and 630
Step-by-step explanation:
whats the area of this shape?
Answer:
54
Step-by-step explanation:
find the area of each shape. you have a length of 3 and a height of 4.
3 • 4 = 12
you have this shape twice so 12 • 2 = 24
now you have a length of 5 and a height of 6.
5 • 6 = 30
so adding up all of the numbers (24 + 30), you have an answer of 54.
The perimeter of a rectangle is 64 feet. If one side of the rectangle has a length of 20 feet. How long is the other side?
Please answer thanks
Answer:
b=12
Step-by-step explanation:
Perimeter=2*(l+b)
64=2*(20+b)
b=12
Answer:
The width is 12 feet
Step-by-step explanation:
If the length is 20 feet, the other side must be 20 feet as well. The perimeter is the addition of all sides of a rectangle. Length: 20 on one side, 20 on other side. Subtract the length from total perimeter and you get 24 feet remaining. Divide 24 by 2. 12 feet for the width.

Answer:
On a coordinate plane, a hyperbola is shown. One curve opens up and to the right in quadrant 1, and the other curve opens down and to the left in quadrant 3. A vertical asymptote is at x = 1, and the horizontal asymptote is at y = 4
Step-by-step explanation:
The given function is presented as follows;
[tex]f(x) = \dfrac{2}{x - 1} + 4[/tex]
From the given function, we have;
When x = 1, the denominator of the fraction, [tex]\dfrac{2}{x - 1}[/tex], which is (x - 1) = 0, and the function becomes, [tex]\dfrac{2}{1 - 1} + 4 = \dfrac{2}{0} + 4 = \infty + 4 = \infty[/tex] therefore, the function in undefined at x = 1, and the line x = 1 is a vertical asymptote
Also we have that in the given function, as x increases, the fraction [tex]\dfrac{2}{x - 1}[/tex] tends to 0, therefore as x increases, we have;
[tex]\lim_ {x \to \infty} \dfrac{2}{(x - 1)} \to 0, and \ \dfrac{2}{(x - 1)} + 4 \to 4[/tex]
Therefore, as x increases, f(x) → 4, and 4 is a horizontal asymptote of the function, forming a curve that opens up and to the right in quadrant 1
When -∞ < x < 1, we also have that as x becomes more negative, f(x) → 4. When x = 0, [tex]\dfrac{2}{0 - 1} + 4 = 2[/tex]. When x approaches 1 from the left, f(x) tends to -∞, forming a curve that opens down and to the left
Therefore, the correct option is on a coordinate plane, a hyperbola is shown. One curve opens up and to the right in quadrant 1, and the other curve opens down and to the left in quadrant 3. A vertical asymptote is at x = 1, and the horizontal asymptote is at y = 4.

Find the surface area of the rectangular prism
Front: 60 cm^2
Area = 6 x 10 = 60
Back: 60 cm^2
Area = 6 x 10 = 60
Right: 30 cm^2
Area = 3 x 10 = 30
Left: 30 cm^2
Area = 3 x 10 = 30
Bottom: 18 cm^2
Area = 6 x 3 = 18
TOTAL: 216 cm^2
Formula I used:
SA of a rectangular prism:
2 (lw + hl + w)
Just use the formula without the “lw”. After you used the formula, just solve for “lw” again and add it back to the final answer. This is because the upper part of the prism is not included.
Answer:
216 square cm
Brainliest, please!
Step-by-step explanation:
A rectangle has 6 sides. 2 are the same, 2 are the same, and the final 2 are the same.
(6 x 10) x 2 = 60 x 2 = 120 (Front + Back)
(3 x 6) x 2 = 18 x 2 = 36 (Top + Bottom)
(3 x 10) x 2 = 30 x 2 = 60 (Left + Right)
120 + 36 + 60 = 216 square cm

Suppose M is the midpoint of XY. If XM = 2x + 11 and MY = 5x - 16, find the value of X.
A) x = -4
B) x = 4
C) x = -9
D) x = 9
E) x = 2
My math:
2x + 11 = 5x + 16
(-5x and -11 from both sides)
-3x=5
(divide -3 on each side)
x=-5/3
But it isn't an option, so I don't know.
Answer:
D
Step-by-step explanation:
Instead of 2x + 11 = 5x + 16, you should have put 2x+11 = 5x - 16. There is a sign change right before the 16, and you may have accidentally written down +16 instead of -16. I think that's where the problem is.
2x + 11 = 5x - 16
subtract 5x from both sides to make all variables on one side
-3x + 11 = -16
subtract 11 from both sides to isolate the x and its coefficient
-3x = -27
divide both sides by -3 to isolate x
x = 9
