The equivalent expression of the given equation is option [tex]\frac{8^6}{4^{12} }[/tex], option B is correct.
How can equivalent expression be determined?Every mathematical statement that includes numbers, variables, and an arithmetic operation between them is known as an expression or algebraic expression. For instance, the formula 4m + 5 has the terms 4m and 5 as well as m, the variable, all separated by the arithmetic sign +.
Given that
[tex](\frac{8^2}{4^4} )^{3}[/tex]
The numerator = [tex](8^{2} )^{3} = 8^{6}[/tex]
The denominator = [tex](4^{4} )^{3} = 4^{12}[/tex]

The measure of arc OS is (4x-18)
What is the value of x?
Answers
Answer:
The value X=49.5
Step-by-step explanation:
Given:
Arc of 4x-18 is formed .
To Find:
Value of x
Solution:
Consider a circle in which arc(OS) is formed ,
with OS as diameter so the angle subtended by them is 180 degree.
...(by property of semi circle )
4x-18 =180 degrees.
4x=198
x=198/4
x=49.5 degrees.
Hence the value of X=49.5 degrees
Answer:49.5
Step-by-step explanation:
Suppose you invested $500 in K-Mart stock in October
of 2001. Each month the stock lost 2% of its value.
How much was the stock worth in October of 2002?
(HINT: The loss is per MONTH.)
Answers
Answer:
$380
Step-by-step explanation:
Amount invested in October 2001 = $500
If 2% is lost on stock each month, amount lost every month will be 2% of $500
= 2/100×$500
= $10
In order to know how much the stock will cost by October 2002, we need to know the number of month there is between October 2001 and October 2002.
The number of months within this period is 12months
If $10 is lost per month, the total stock lost for 12months will be
$10×12 = $120
Stock worth by October 2002 = Money invested - Total stock loss
Stock worth by October 2002 = $500-$120
= $380

Which pair of angles is classified in the same category according to the angle measure?
Answers
Hello! Remember you have to write complete questions in order to get good and exact answers. Here I'll help you in a general way. Let's mention some categories:
1. Category of congruence:
Angles are congruent if they have the same measure. So if we have two angles:
[tex]\angle A=30^{\circ} \\ \\ \angle B=30^{\circ}[/tex]
Then they are congruent. In other words:
[tex]\angle A \cong \angle B[/tex]
1. Category of complementary angles:
Two angles are complementary if they add up to 90 degrees. So if we have:
[tex]\angle A=30^{\circ} \\ \\ \angle B=60^{\circ}[/tex]
They are complementary because:
[tex]\angle A+ \angle B=30^{\circ}+60^{\circ}=90^{\circ}[/tex]
1. Category of supplementary angles:
Two angles are supplementary if they add up to 180 degrees. So if we have:
[tex]\angle A=110^{\circ} \\ \\ \angle B=70^{\circ}[/tex]
They are supplementary because:
[tex]\angle A+ \angle B=110^{\circ}+70^{\circ}=180^{\circ}[/tex]

Final Answer:
It's likely that the student is concentrating on a factoring problem. The two numbers are 5 and 3, which when multiplied together equal 8 (the small number) and 15 (the big number).
Explanation:
It appears that you are looking for two numbers that sum up to 8 and multiply by 15, since the bottom number is 8 and the top number is 15.In this case, the appropriate responses are 5 and 3. Specifically, this is why: the sum equals 5 + 3 = 8.15 is the result of multiplying 5 by 3.
So, 5 and 3 are the numbers you're looking for.

A circle with the equation (x + 4)2 + (y + 2)2 = 36 is reflected over the line x = 1. What is the equation of the image? (x + 4)2 + (y - 2)2 = 36 (x - 6)2 + (y + 2)2 = 36 (x + 6)2 + (y - 2)2 = 36 (x - 4)2 + (y + 2)2 = 36
Answers
Answer:
B
Step-by-step explanation:
Currently, the graph looks like the attachment.
The centre of this circle is at (-4, -2), but when we flip it over the line x = 1 (the blue line on the picture), the centre will become ((1- -4) + 1, -2) = (6, -2).
Look for the equation [tex](x-h)^2+(y-k)^2=r^2[/tex] that matches this center. We want the center (h, k) to be (6, -2), so our equation should look something like:
[tex](x-6)^2+(y+2)^2=36[/tex]
The answer is B.
Answer:
(x - 6)² + (y + 2)² = 36
Step-by-step explanation:
Centre before reflection: (-4,-2)
Centre after reflection:
(-4+5+5,-2) = (6,-2)
(x - 6)² + (y + 2)² = 36
A slide and its ladder form a right triangle with the ground, with the
slide representing the hypotenuse. The top of the ladder is 10 feet above
the ground, and the bottom of the ladder is 12 feet from the bottom of
the slide. What is the length of the slide to the nearest tenth of a foot?
Answers
Answer:
15.6 ft
Step-by-step explanation:
Let's call
a: distance from the top of the ladder to the ground = 10 ftb: distance from the bottom of the ladder to the bottom of the slide = 12 ftc: length of the slideFrom Pythagorean theorem:
c² = a² + b²
c = √(10² + 12²)
c = 15.6 ft
The length of the slide, which forms the hypotenuse of a right-angled triangle with the ground, is approximately 15.6 feet to the nearest tenth of a foot when calculated using the Pythagorean Theorem.
Explanation:The question involves finding the length of a slide (hypotenuse) when its ladder and the ground form a right-angled triangle. The top of the ladder is 10 feet above the ground (opposite side), and the bottom of the ladder is 12 feet away from the bottom of the slide (adjacent side). We will use the Pythagorean Theorem to solve for the slide's length, which is represented by the equation a² + b² = c², where a and b are the lengths of the legs of the triangle and c is the length of the hypotenuse.

A cone has a slant height of 26 inches and a diameter of 48 inches. What is the volume of the cone?
Answers
Answer:
Approx. 28952.92
Step-by-step explanation:
Because cone volume is found by V=πr²[tex]\frac{h}{3}[/tex].
First you find the radius. Because you have the diameter, you divide that by two, because it's 48, and diameter is radius multiplied by 2. So the radius is 24. 24pi squared with height divided by three is volume so, 28952.92.

What is a cone?It is a shape of a Christmas tree where there is a base of radius r and a top point called the apex.
The volume of a cone is 1/3πr²h.
We have,
Diameter = 48 inches
Radius = 24 inches
r = 24 inches
Slant height = 26 inches
L = 26 inches
L² = h² + r²
26² = h² + 24²
h² = 676 - 576
h² = 100
h = 10 inches
The volume of the cone.
= 1/3 x π x 24 x 24 x 10
= 3.14 x 8 x 24 x 10
= 6028.8 inches³
Thus,
The volume of the cone is 6028.8 inches³.

Answers
Step-by-step explanation:
Given the area of the Parallelogram
[tex]A=\:7.5\:m^2[/tex]
The area of a parallelogram is defined as the multiplication of its base and height.so
A = base × height
Plugging A = 7.5 m² in above equation
7.5 m² = base × height
height = base ÷ 7.5 m²
Therefore, height of the parallelogram with area 7.5 m² is : base ÷ 7.5 m²
The difference between two numbers is 55. If the smaller number is increased by 15 and the bigger number is decreased by 15. What will be the new difference?
Answers
Answer:
25
Step-by-step explanation:
Lets say the numbers are 100 and 45.
If the smaller number is increased by 15
45+15=60
the bigger number is decreased by 15
100-15= 85
What will be the new difference?
85-60= 25
The new difference will be 25.
Given that,
The difference between the two numbers is 55.
If the smaller number is increased by 15 and the bigger number is decreased by 15.
We have to determine,
What will be a new difference?
According to the question,
Let the first number be x,
And the second number be y.
The difference between the two numbers is 55.
x + y = 55
The smaller number is increased by 15,
Then,
The number is,
45 + 15 = 60
And the bigger number is decreased by 15,
Then,
The number is,
100 - 15 = 85
Therefore,
The new difference between the new number is,
85 - 60 = 25
Hence, The new difference will be 25.
