Answer:
b = 16
Step-by-step explanation:
× stands for varies
a × √bc,
a = k√bc,
when a = 24, b = 8, c= 2
a = k√bc
24 = k√8•2
24 = k√16
24 = 4k
dividing both sides by 4
k = 24/4
k = 6
a = 6√bc (standard equation)
find b when a = 48 and c = 4
a = 6√bc
48 = 6√b•4
dividing both sides by 6
48/6 = √b•4
8 = √b•4
squaring both sides
8^2 = b•4
64 = b•4
b = 64/4
b= 16.
Thrrefore when a = 48, c = 4, b = 16.
Check whether A{x:x2 =25 and 6x= 125} is an empty set or not
Given:
The set is
[tex]A=\{x:x^2=25\text{ and }6x=125\}[/tex]
To find:
Whether the given set is empty or not.
Solution:
A set is called empty set if it has no elements.
We have,
[tex]A=\{x:x^2=25\text{ and }6x=125\}[/tex]
We need to find the solutions of [tex]x^2=25[/tex] and [tex]6x=125[/tex]. The common solutions of these two equations are the elements of given set.
[tex]x^2=25[/tex]
[tex]x=\pm \sqrt{25}[/tex]
[tex]x=\pm 5[/tex]
[tex]x=5,-5[/tex] ...(i)
And,
[tex]6x=125[/tex]
[tex]x=\dfrac{125}{6}[/tex]
[tex]x\approx 20.83[/tex] ...(ii)
From (i) and (ii) it is clear that, there is no common value of x which satisfy both equations [tex]x^2=25[/tex] and [tex]6x=125[/tex].
Since there is no element in set A, therefore, the given get A is an empty set.

Square A is 3cm long. The scale that maps Square A onto square b is 1:4. What is the length of square B?
The length of square B is 12 cm.
What is scale factor?A scale factor is defined as the ratio between the scale of a given original object and a new object, which is its representation but of a different size (bigger or smaller).
The basic formula to find the scale factor of a figure is expressed as,
Scale factor = Dimensions of the new shape ÷ Dimensions of the original shape.
Given that, square A is 3 cm long.
The scale that maps square A onto square B is 1:4.
Let the length of square B be x.
1/4 =3/x
x=4×3
x=12 cm
Therefore, the length of square B is 12 cm.

Simplify the expression: 3x2⋅x2=
a
3x
b
3x4
c
3x2+2
Answer:
The quadratic equations and their solutions are;
9 ± √33 /4 = 2x² - 9x + 6.
4 ± √6 /2 = 2x² - 8x + 5.
9 ± √89 /4 = 2x² - 9x - 1.
4 ± √22 /2 = 2x² - 8x - 3.
Explanation:
Any quadratic equation of the form, ax² + bx + c = 0 can be solved using the formula x = -b ± √b² - 4ac / 2a. Here a, b, and c are the coefficients of the x², x, and the numeric term respectively.
We have to solve all of the five equations to be able to match the equations with their solutions.
2x² - 8x + 5, here a = 2, b = -8, c = 5. x = -b ± √b² - 4ac / 2a = -(-8) ± √(-8)² - 4(2)(5) / 2(2) = 8 ± √64 - 40/4. 24 can also be written as 4 × 6 and √4 = 2. So x = 8 ± 2√6 / 2×2= 4±√6/2.
2x² - 10x + 3, here a = 2, b = -10, c = 3. x =-b ± √b² - 4ac / 2a =-(-10) ± √(-10)² - 4(2)(3) / 2(4) = 10 ± √100 + 24/4. 124 can also be written as 4 × 31 and √4 = 2. So x = 10 ± 2√31 / 2×2 = 5 ± √31 /2.
2x² - 8x - 3, here a = 2, b = -8, c = -3. x = -b ± √b² - 4ac / 2a = -(-8) ± √(-8)² - 4(2)(-3) / 2(2) = 8 ± √64 + 24/4. 88 can also be written as 4 × 22 and √4 = 2. So x = 8 ± 2√22 / 2×2 = 4± √22/2.
2x² - 9x - 1, here a = 2, b = -9, c = -1. x = -b ± √b² - 4ac / 2a = -(-9) ± √(-9)² - 4(2)(-1) / 2(2) = 9 ± √81 + 8/4. x = 9 ± √89 / 4.
2x² - 9x + 6, here a = 2, b = -9, c = 6. x = -b ± √b² - 4ac / 2a = -(-9) ± √(-9)² - 4(2)(6) / 2(2) = 9 ± √81 - 48/4. x = 9 ± √33 / 4 .

Answer: -4096
Step-by-step explanation:
The 6th term of the geometric sequence is; -4096.
What is a geometric sequence?A geometric sequence is a sequence in which the result of the division of consecutive terms is always the same, called common ratio q.
The nth term of a geometric sequence is given as:
[tex]a_n = a_1q^{n-1}[/tex]
In which a1 is the first term.
For this problem, we have :
The first term is a1 = 4 and an =- 4 an–1 .
Therefore, the common ratio is q = -4.
Now the 6th term of the sequence is found as :
[tex]a_6 = 4(-4)^{5[/tex]
a_6 = - 4096

What is the theoretical probability that two coins flipped together will both land on tails?
What is the theoretical probability that two coins flipped together will both land on heads?
What is the theoretical probability that two coins flipped together will land on heads and tails?
Answer:
1.We say a coin is fair if it has probability 1/2 of landing heads up and probability 1/2 of landing tails up. What is the probability that if we flip two fair coins, both will land heads up? It seems plausible that each should be equally likely. If so, each has probability of 1/4.
2.The probability of getting heads on the toss of a coin is 0.5. If we consider all possible outcomes of the toss of two coins as shown, there is only one outcome of the four in which both coins have come up heads, so the probability of getting heads on both coins is 0.25.
3.his states that the probability of the occurrence of two mutually exclusive events is the sum of their individual probabilities. As you can see from the picture, the probability of getting one head and one tail on the toss of two coins is 0

a cylinder has a base diameter of 6 feet and a height of 2 feet . what is its volume in cubic feet, to the nearest tenths place?
The Volume of cylinder in cubic unit is 56.52 feet³.
What is Volume?'Volume' is a mathematical quantity that displays the amount of three-dimensional space occupied by an item or a closed surface in mathematics.
A volume is just the amount of space taken up by any three-dimensional solid. A cube, a cuboid, a cone, a cylinder, or a sphere are examples of solids.
We have,
Diameter = 6 feet
Radius = 6/2 = 3 feet
Height = 2 feet
So, the Volume of Cylinder
= πr²h
= 3.14 (3)² (2)
= 3.14(9) 2
= 3.14 (18)
= 56.52 feet³

Answer:
8: 90 degrees, 9: 165 degrees, 6: 81 degrees, 7: angles in the same segment are equal
Step-by-step explanation:
For question 8:
Notice how the line AB just barely touches the edge of the circle. We call this kind of line a tangent. The point O is at the center of the circle so the line OB is a radius. The angle between a tangent and a radius is always 90 degrees, so ABO is 90 degrees.
For question 9:
By the exact same logic as 8, ACO is also 90 degrees. The sum of interior angles in a 4 sided shape (a quadrilateral) is always 360 degrees. This means that 15 + 90 + 90 + x = 360 = 195 + x so x = 360 - 195 = 165
For question 6/7:
We use the theorem that the angles in the same segment are equal. This means that a is 81 degrees.

Answer:
a) Circumference of the circle = 56.52 in
b) Area of the circle = 254.34 in²
Step-by-step explanation:
Mr. Bernard needs to order boxes for his 18-inch diameter "Super Pizza."
Note that:
Pizza is Circular in shape
a) What is the approximate circumference of the Super Pizza? Use 3.14 for π. Show your work.
The formula for the circumference of a circle when given that diameter = πD
Where D = Diameter of the circle = 18 in
π = 3.14
Hence,
Circumference of the circle = 3.14 × 18 in
= 56.52 in
b) What is the approximate area of the Super Pizza? Use 3.14 for π. Show your work.
The formula for the area of a circle = πr²
Radius = Diameter/2
Diameter = 18 in
Radius = 18 in/2 = 9 in
The area of the circle = 3.14 × 9²
= 254.34 in²

round 21.24833 to three decimal places
Answer:
21.248
Step-by-step explanation:
The required value of decimal value 21.24833 to three decimal points is 21.248.
Given that,
21.24833, to round this number to 3 decimal places.
In mathematics, it deals with numbers of operations according to the statements.
Recurring Decimal is defined as also named repeating decimal, is a decimal number that only consists of repeating digits after a certain interval after the decimal. For example, 94.642642642..., 213.569569... etc.
In the question, a decimal value is given, 21.2488, and asked to round this off to 3 decimal places.
When rounding off the number, we check the preceding value neared to which zero either to 0 or 10. if it is near 0 the value before is round off value and the preceding value is near 10 then the value before the proceeding value is increased by 1.
In our case, the value after the third decimal is 3 which is near 0 so nothing will change and the value terminates as it is after 3 decimal points i.e 21.248.
Thus, the required value of decimal value 21.24833 to three decimal points is 21.248.
