Answer:
{ 9/2 , square root of 100, 5.123}
Step-by-step explanation:
The answer would be an option (D) {5.123..., 1/2, -65}. This set does not contain any irrational numbers.
What are real numbers?Real numbers are defined as the value of a continuous quantity that can represent a distance along a line of a real number in mathematics. Rational and irrational numbers are both real numbers. Rational numbers such as integers (-7, 0, 4), fractions(5/2,7/2, 4.2), and irrational numbers such as √5, π, etc., are all real numbers.
According to the given options
(A) {-5.12,pi,30}
Here the irrational number is pi
(B) {square root of 80, 100, 6.56}
Here the irrational number is the square root of 80 i.e. (√80)
(C) { 9/2, square root of 100, 5.123}
Here the irrational number is the square root of 100i.e. (√100)
(D) {5.123..., 1/2, -65}
Here this set does not contain any irrational numbers
Hence, the answer would be option (D) {5.123..., 1/2, -65}. This set does not contain any irrational numbers.

A 20 packet box of detergent sells for $5.49. What is the unit rate?
Answer:
if rounded to 5.50 it would be: .27¢ for 1 packet
Step-by-step explanation:
5.4 divided by 20 is .27 and 5.5 divided by 20 is .275 but .28 multiplied by 20 is over 5.50 which means it would be .27 cents for 1 packet :)

Evaluate 4+2(7) help me
Answer:
18
Step-by-step explanation:
4 + 2(7)
This equation can be rewritten like this: 4 + 2 x 7
According to the order of operations, multiplication comes before addition.
So, we can go ahead and multiply 2 and 7 out:
4 + 2 * 7
4 + (2 * 7)
4 + (14)
Then, our second step is to add.
4 + 14 = 18
So, 4 + 2(7) = 18.

In rhombus, WY= 18 cm and XV=8 cm.
Find the area of the rhombus.
Be sure to include the correct unit in your answer.
The area of the rhombus is [tex]72 \ cm^2[/tex]
Explanation:
It is given that in a rhombus VWXY, the length of the diagonals are [tex]\mathrm{WY}=18 \ {cm}[/tex] and [tex]X V=8 \ {cm}[/tex]
The area of the rhombus can be determined by multiplying the diagonals and dividing by 2.
The area of the rhombus can be determined using the formula,
[tex]A=\frac{p q}{2}[/tex]
where p and q are diagonals of the rhombus.
Substituting the values in the formula, we have,
[tex]A=\frac{18\times 8}{2}[/tex]
Multiplying the numerator, we get,
[tex]A=\frac{144}{2}[/tex]
Dividing by 2, we have,
[tex]A=72 \ cm^2[/tex]
Thus, the area of the rhombus is [tex]72 \ cm^2[/tex]
A valume of a graduated cylinder is 490 cubic cm.
The radius of the base is 7 cm. What is the height??
Please help me
Answer:
The height is 3.183 cm.
Step-by-step explanation:
The volume [tex]V[/tex]of a cylinder with base radius [tex]r[/tex] and height [tex]h[/tex] is given by
[tex]V = \pi r^2h[/tex]
Now, if the volume and the radius is given, we can use this equation to work out the height of the cylinder:
[tex]h= \dfrac{V}{\pi r^2 }.[/tex]
For our graduated cylinder,
[tex]V = 490cm^3[/tex]
[tex]r = 7cm[/tex];
therefore,
[tex]h = \dfrac{490cm^3}{\pi (7cm)^2 }[/tex]
[tex]\boxed{h = 3.183\:cm}[/tex]
Thus, the height of the graduated cylinder is 3.183 cm.

The sequence is geometric because it decreases by a factor of 1/27.
What happens in am arithmetic and geometric sequeceIn an arithmetic sequence, the terms change by a constant difference, while in a geometric sequence, the terms change by a constant ratio. In this case, the terms of the sequence are decreasing, and the ratio between consecutive terms is 1/27, which is a constant factor.
For example, if the sequence were arithmetic, you would see a consistent subtraction of a fixed number from one term to the next.
Therefore, the sequence is geometric because it follows the pattern of a geometric progression.

∠A and \angle B∠B are supplementary angles. If m\angle A=(3x+18)^{\circ}∠A=(3x+18)
∘
and m\angle B=(5x+2)^{\circ}∠B=(5x+2)
∘
, then find the measure of \angle A∠A.
[tex]\bf \stackrel{\textit{we know that they are supplementary}}{\stackrel{\measuredangle A}{(3x+18)}~~ + ~~\stackrel{\measuredangle B}{(5x+2)}}~~ = ~~180 \implies 8x+20=180\implies 8x=160 \\\\\\ x=\cfrac{160}{8}\implies \boxed{x = 20} ~\hfill \stackrel{\measuredangle A}{3(20)+18}\implies 78[/tex]
Final answer:
The measure of ∠A, when ∠A and ∠B are supplementary, is found to be 78° after setting up an equation, simplifying it, and solving for x.
Explanation:
If ∠A and ∠B are supplementary angles, the sum of their measures is 180°. We have m∠A=(3x+18)° and m∠B=(5x+2)°. Set up an equation to find the value of x:
3x + 18 + 5x + 2 = 180.
Simplify and solve the equation:
8x + 20 = 180
8x = 160
x = 20
Now, substitute x back into the expression for m∠A:
m∠A = 3(20) + 18
m∠A = 60 + 18
m∠A = 78°
So, the measure of ∠A is 78°.
Sara and Gordon win some money and share it in the ratio 2:1. Sara gets £20. How much did they win in total
Answer:
They won £30 in total
Step-by-step explanation:
∵ Sara and Gordon win some money
∵ They share it in the ratio 2 : 1
∵ Sara gets £20
- To solve the problem lets use the ratio method
→ Sara : Gordon
→ 2 : 1
→ 20 : x
By using cross multiplication
∵ 2 × x = 1 × 20
∴ 2 x = 20
- Divide both sides by 2
∴ x = 10
∵ x represents the share of Gordon
∴ Gordon gets £10
- Add their shares to find the total
∴ The total = 20 + 10 = 30
∴ They won £30 in total

If 4+2=26,8+1= 79 and 6+5=111 then what is 7+3
The answer is 70.
Explanation:The given pattern seems to follow the rule of multiplying the first number by the sum of its digits and adding the result to the second number:
For example:
4 + 2 = (4 x (4+2)) = 26
8 + 1 = (8 x (8+1)) = 79
6 + 5 = (6 x (6+5)) = 111
Therefore, for 7 + 3:
7 + 3 = (7 x (7+3)) = 70

Let us plot the first point [tex]1\frac{4}{9}[/tex].
1 unit is completed. So count after 1 (indicated) in the number line.
point after 1 is [tex]1\frac{1}{9}[/tex]
point after [tex]1\frac{1}{9}[/tex] is [tex]1\frac{2}{9}[/tex]
point after [tex]1\frac{2}{9}[/tex] is [tex]1\frac{3}{9}[/tex]
point after [tex]1\frac{3}{9}[/tex] is [tex]1\frac{4}{9}[/tex].
So, move 4 points after 1 in the number line is [tex]1\frac{4}{9}[/tex].
Now plot the point [tex]2\frac{1}{3}[/tex].
To make the denominator 9, multiply and divide numerator and denominator by 3.
[tex]$2 \frac{1}{3}=2 \frac{3}{9}[/tex]
2 unit is completed. So count after 2 (indicated) in the number line.
point after 2 is [tex]2\frac{1}{9}[/tex]
point after [tex]2\frac{1}{9}[/tex] is [tex]2\frac{2}{9}[/tex]
point after [tex]2\frac{2}{9}[/tex] is [tex]2\frac{3}{9}=2\frac{1}{3}[/tex]
So, move 3 points after 2 in the number line is [tex]2\frac{1}{9}[/tex].

Kellie and her sister Ashley are training for a race. Kellie ran 8 miles in 72 minutes. Ashley ran 12 miles in 102 minutes.
(a) What is Kellie’s minute-per-mile pace?
(b) How far did Ashley run in 34 minutes?
(c) What was the difference in Kellie and Ashley’s times after they ran 4 miles?
A. Kellie's minute-per-mile pace 9 minutes per mile.
To find this, divide her time (72 minutes) by the number of miles she went (8). 72 divided by 8 is 9 minutes per mile.
B. Ashley ran 4 miles in 34 minutes. First, divide Ashley's time (102 minutes) by the number of miles she went (12). 102 divided by 12 is 8.5 minutes per mile. Then divide 34 by 8.5 to get how far she went in that time. Thus meaning 4 miles.
C. The difference in time between their 4 miles is 2 minutes. Kellie took 36 minutes to go 4 mile (4 miles times 9 minutes is 36 minutes) and Ashley took 34 minutes to go 4 miles (as stated in part B.) Lastly, subtract 34 from 36 to get the 2 minute difference.
I hope this helps!

y=x+2 2x-y=-4 Solve the systems of equations
Answer:
Step-by-step explanation:
Given that,
y=x+2 equation 1
2x-y=-4 equation 2
This is a simultaneous equation.
Substitute equation 1 into equation 2
2x-y=-4. Since y=x+2
2x-(x+2) = -4
2x-x-2 = -4
x-2 = -4
x = -4+2
x = -2
Also from equation 1
y=x+2
Since x=-2
y=-2+2
y=0
Then, solution (x, y) = (-2,0)
Answer: x = -2, y = 0
Step-by-step explanation:
[tex]y=x+2\\2x-y=-4[/tex]
Substitute y = x+2 in [tex]2x-y=-4[/tex]
Then we get, [tex]2x-(x+2)=-4[/tex]
[tex]2x-x-2=-4\\x-2=-4\\x=-4+2\\x=-2[/tex]
Then substitute x = -2 in any equations, just only one equation. For me, I'd substitute x = -2 in y = x+2
[tex]y=-2+2y=0[/tex]
So the answer is x = -2 and y = 0
