Answer:
Option 1 , 2 & 5
Step-by-step explanation:
4 & 16 are perfect squares. So , 1/4 & 1/16 are also perfect squares. But 2 , 8 & 10 are not perfect squares. So root of 1/2 , 1/8 & 1/10 are irrational numbers.
Verification :-
1)[tex] \sqrt{ \frac{1}{10} } = \frac{ \sqrt{1} }{ \sqrt{10} } = \frac{1}{ \sqrt{2} \times \sqrt{5} } [/tex]
Hence , it is irrational.
2)[tex] \sqrt{ \frac{1}{8} } = \frac{ \sqrt{1} }{ \sqrt{8} } = \frac{1}{2 \sqrt{2} } [/tex]
So , it is irrational.
3)[tex] \sqrt{ \frac{1}{16} } = \frac{ \sqrt{1} }{ \sqrt{16} } = \frac{1}{4} [/tex]
So , it is rational.
4) [tex] \sqrt{\frac{1}{4} } = \frac{ \sqrt{1} }{ \sqrt{4} } = \frac{1}{2} [/tex]
So it is rational.
5) [tex] \sqrt{ \frac{1}{2} } = \frac{ \sqrt{1} }{ \sqrt{2} } = \frac{1}{ \sqrt{2} } [/tex]
Hence it is irrational.

Answers
Answer:
15 units
Step-by-step explanation:
ΔADC is an isosceles triangle because it has 2 equal sides
AB = BC (DB is median so cuts AC into 2 equal parts)
AB = 5x, BC = 4x + 3
5x = 4x + 3
5x - 4x = 4x - 4x + 3 (subtracting 4 from both sides)
x = 3
AB = 5x
= 5(3)
= 15 units

Answers
Answer:
x = 70
Step-by-step explanation:
The 2 given angles are same- side interior angles and are supplementary, that is sum to 180° , then
45 + 2x - 5 = 180, that is
2x + 40 = 180 ( subtract 40 from both sides )
2x = 140 ( divide both sides by 2 )
x = 70

The ratio of males to females was 4:5. If there are 180 people at the fair how many males
are there?
Answers
9514 1404 393
Answer:
80
Step-by-step explanation:
Let m represent the number of males. Then you have ...
m/(180 -m) = 4/5
5m = 4(180 -m) . . . . cross multiply
9m = 720 . . . . . . . . add 4m, simplify
m = 80 . . . . . . . . . . divide by 9
The number of males at the fair was 80.

Joanna had four candy bars. She wanted to find out how many people could share the bars if each person received 2/3 of a bar. Use the candy bar picture below to help you.
What is the answer to Joanna's question?
Kindly find attached candy bar picture below
Answer:
6 people
Step-by-step explanation:
From the picture, each candy bar has already been divided equally into 3. Since we have 4 candy bars. The total number of divisions we have is ; (3 * 4 = 12 candy units).
Since each person is taking 2/3 of a bar, this is equal to 2 units of candy
Hence, number of people who could share the bar :
Total units or division / units person
12 / 2
= 6 people

The area of a rectangle is 588 in^2. The ratio of the length to the width is 4:3. Find the length and the width
Answers
Answer:
Length is 336 in, width is 252 in
Step-by-step explanation:
Divide 588 by 7 which equals 84. Since this one-seventh, and the given ratio is 4:3, multiply 84 by 4 for the length and 84 by 3 for the width.
The length and the width of the rectangle are 28 in and 21 in, respectively.
What is the area of the rectangle?The area of a rectangle is defined as the product of the length and width.
The area of a rectangle = L × W
Where W is the width of the rectangle and L is the length of the rectangle
Let's assume the length of the rectangle is 4x, and the width is 3x, where x is a common factor.
The area of a rectangle is given by the formula:
Area = Length × Width.
Given that the area is 588 in², we can set up the equation:
(4x)(3x) = 588
12x² = 588
Dividing both sides of the equation by 12:
x² = 588 / 12
x² = 49
Taking the square root of both sides:
x = √49
x = 7
So, x = 7.
Now we can find the length and width:
Length = 4x = 4(7) = 28 inches
Width = 3x = 3(7) = 21 inches
Therefore, the length of the rectangle is 28 inches, and the width is 21 inches.

A company rents two storage units. Both units are cube- shaped. What is the difference in volume of the two storage units? Note that the volume of a cube a square is s(2) , where is the side length. Explain.
Answers
Answer:
The difference between their volumes is [tex]237.375ft^3[/tex]
Step-by-step explanation:
The attachment completes the question.
For cube 1:
[tex]s_1 = 8ft[/tex]
For cube 2:
[tex]s_2 = 6.5ft[/tex]
Required
The difference in their volumes
First, we calculate the volume of box 1
[tex]V_1 = s_1^3[/tex]
Substitute 8 for s1
[tex]V_1 = 8^3[/tex]
[tex]V_1 = 512ft^3[/tex]
Next, we calculate the volume of box 2
[tex]V_2 = s_2^3[/tex]
Substitute 6.5 for s2
[tex]V_2 = 6.5^3[/tex]
[tex]V_2 = 274.625ft^3[/tex]
The difference is then calculated as:
[tex]Difference = |V_1- V_2|[/tex]
[tex]Difference = |274.625- 512|[/tex]
[tex]Difference = |-237.375|[/tex]
[tex]Difference = 237.375[/tex]
Hence, the difference between their volumes is [tex]237.375ft^3[/tex]

What is the area of the given circle? Use 3.14 for it.
A)
56.52 cm2
B)
254.34 cm2
C)
324.09 cm2
D)
1017.36 cm2
Answers
Answer: B. 254.34 cm^2
Step-by-step explanation:
The area of a circle is pi times the radius squared.
Using the diameter we have to find the radius.
The diameter is two times the radius meaning that the radius is half the diameter.
18/ 2 = 9
The radius will be 9 cm
Now using the formula v= pi * r^2 , input the value for pie and the radius and solve for v the volume
v = 3.14 * 9^2
v= 3.14 * 81
v = 254.34 cm^2
Answer:
The answer would be B) 254.34 cm2

Answer:
x = [tex]\frac{16}{3}[/tex]
Step-by-step explanation:
The outer and inner triangles are similar, thus the ratios of corresponding sides are equal, that is
[tex]\frac{6}{6+12}[/tex] = [tex]\frac{x}{16}[/tex] , that is
[tex]\frac{6}{18}[/tex] = [tex]\frac{x}{16}[/tex] ( cross- multiply )
18x = 96 ( divide both sides by 18 )
x = [tex]\frac{96}{18}[/tex] = [tex]\frac{16}{3}[/tex]
