What is the correct expanded form and value of (One-fifth) Superscript 4?
One-fifth + one-fifth + one-fifth + one-fifth = StartFraction 4 Over 5 EndFraction
One-fifth times one-fifth times one-fifth times one-fifth = StartFraction 1 Over 625 EndFraction
StartFraction 1 + 1 + 1 + 1 Over 5 times 4 EndFraction = StartFraction 4 Over 20 EndFraction
One-fifth times 4 = StartFraction 4 Over 5 EndFraction
Answers
Answer:
One-fifth times one-fifth times one-fifth times one-fifth = StartFraction 1 Over 625 EndFraction
Step-by-step explanation:
1/5^4 = 1/5 * 1/5 * 1/5 *1/5 = 1/625
The expanded form of (One-fifth)⁴ is "StartFraction 1 Over 5 EndFraction times StartFraction 1 Over 5 EndFraction times StartFraction 1 Over 5 EndFraction times StartFraction 1 Over 5 EndFraction," and its value is "StartFraction 1 Over 625 EndFraction."
The expanded form of (One-fifth)⁴ can be derived by multiplying (1/5) four times. Each multiplication represents multiplying by one-fifth, resulting in "StartFraction 1 Over 5 EndFraction times StartFraction 1 Over 5 EndFraction times StartFraction 1 Over 5 EndFraction times StartFraction 1 Over 5 EndFraction." This can be further simplified as "StartFraction 1 Over 625 EndFraction" by multiplying the numerators and the denominators separately.
In mathematical terms, when we raise one-fifth to the power of 4, we are essentially multiplying one-fifth by itself four times. Thus, (One-fifth)⁴ is equal to "StartFraction 1 Over 5 EndFraction times StartFraction 1 Over 5 EndFraction times StartFraction 1 Over 5 EndFraction times StartFraction 1 Over 5 EndFraction."
Evaluating this expression yields the value "StartFraction 1 Over 625 EndFraction" since multiplying the numerators (1 * 1 * 1 * 1) and the denominators (5 * 5 * 5 * 5) results in 1 and 625, respectively.
Mathematical representation: \(\frac{1}{5}^4= \frac{1}{5} * \frac{1}{5} * \frac{1}{5} * \frac{1}{5}\)

A group of hikers park their car at a trail head and hike into the forest to a campsite. The next morning, they head out on a hike from their campsite walking at a steady rate. The graph shows their distance in miles, d, from the car on the day of their hike after h hours.
a. How far is the campsite from the car? How do you know?
b. Write an equation that describes the relationship between d and h.
c. After how many hours will the hikers be 24 miles from their car? How do you know?
Answers
Answer:
a. 3
b. h = 1/3d + 3
c. 7 hours because they started at 3 miles and moved at a constant rate of 3 miles per hour
Step-by-step explanation:
for question A it's 3 because they went on a hike from their campsite, not their car and the graph is the distance from their car since the graph starts at 3 this means that the campsite is 3 miles from their car.
for question B it's h = 1/3d because if you look at the graph you can take where two of the points on the line are on a cross-section of the graph and see how many hours and miles there are between the two, then just take the y-intercept or in this case the h intercept and put it after the x or in this case d. Then just simplify the equation, so that the y(d) side is equal to 1, ie: instead of 2y = 8x + 4 its y = 4x + 4.
and finally, for question C, you can just plug the x(d) and y(h) value that is given in this case d = 24, and plug it in so h = 1/3d + 3 becomes h = 24/3 + 3
h=1/3d+3
c: 7 hrs because they started at 3 miles away and went 3 mphs
There are 5 blue socks in Josh’s drawer. After he removes 3 non-blue socks, the probability to pick a blue sock at random becomes . How 1/7 many non-blue socks were in Josh’s drawer originally?
Answers
Answer: There is 5 non blue sock in Josh's drawer
Step-by-step explanation:
The denominator shows the total of nonblue and blue socks. So there are 7 non-blue and blue socks in the drawer after he removes 3 non blue socks.To find how many non-blue where in the drawer originally you need to find how many non blue are in the draw after removing the three. So you subtract 7 from 5 which gives you 2. So there are 2 non-blue socks in the drawer after removing the three. Now you need to find how many non-blue were there before he removed the three. So add the 3 non blue socks that he removed to the two that were there after which gives you five.

Show that AC and BD bisect each other if A(–3, –5), B(2, –3), C(3, 5), and D(–2, 3). Find AC and BD
Answers
Answer:
Step-by-step explanation:
midpoint of AC=((-3+3)/2,(-5+5)/2)=(0,0)
midpoint of BD=((2-2)/0,(-3+3)/2)=(0,0)
coordinates of midpoint of AC and BD are same.
∴ AC and BD bisect each other.
\(AC=\sqrt{(3-(-3))^2+(5-(-5))^2 } =\sqrt{6^2+10^2} =\sqrt{136} =2\sqrt{39} \\BD=\sqrt{((-2-2)^2+(3-(-3))^2} =\sqrt{16+36} =\sqrt{52} =2\sqrt{13}\)
Midpoint of AC and BD is ( 0, 0 ), so both bisects each other.
The value of AC = 2 √39 and BD = 2 √13
Here, points given as,
A(–3, –5), B(2, –3), C(3, 5), and D(–2, 3).
We have to find, AC and BD.
What is distance between two points?
Distance between two points \(P(x_{1} ,y_{1} )\) and \(Q(x_{2} ,y_{2} )\) is given by:
\(d(P, Q) = \sqrt{(x_{2}- x_{1} )^2 +(y_{2}- y_{1} )^2 }\)
Now,
Midpoint of AC = \((\frac{-3+3}{2} ), (\frac{-5+5}{2} ) = ( 0, 0 )\)
Midpoint of BD = \((\frac{-2+2}{2} ), (\frac{-3+3}{2} ) = ( 0, 0 )\)
Hence, Both AC and BD bisects each other.
And, Distance between A and C is,
AC = \(\sqrt{(3 - (-3))^2 +(5 - (-5))^2 } = \sqrt{36 + 100} = \sqrt{136} = 2\sqrt{39}\)
Distance between B and D is,
BD = \(\sqrt{( -2 -2))^2 +(3 - (-3))^2 } = \sqrt{16 + 36} = \sqrt{52} = 2\sqrt{13\)

What is area ?Area is the measure of a region's size on a surface. The area of a plane region or plane area refers to the area of a shape or planar lamina, while surface area refers to the area of an open surface or the boundary of a three-dimensional object. Area of a square (A) is the product of its length (l) and width (l).
i.e. A= l× l
here, we have,
to find the area of a square with coordinates:
The area of a square is given by;
A = L²
where;
L is the length of the side of the square
The sides of a square all have the same length, and as such we just need to find the length of one side.
The length of the side of the square here is the distance between two vertices, which can be calculated as
L = √[(x₂ - x₁)² + (y₂ - y₁)²]
However, to avoid long process, since it is a square, we can use subtraction of coordinates to get the side length which is gotten by using the first 3 coordinates;
Horizontal length = (6 + 6) = 12
Thus;
Area = L² = 12² = 144 in²
Hence, The area, in square inches, of the painted face of the brick is;
144 in².

For each ride, a taxi service charges an initial fee plus an additional fee based on the number of kilometers of the trip. The graph shows the cost for taxi rides. Select a true statement. The rise is 4 while the run is 2. The selection of answers are:
A: The slope is 2.1. This means that each kilometer costs $2.10.
B: The slope is 5. This means that each kilometer costs $5.
C: The y-intercept is 2.1. This means that the initial fee is $2.10.
D: The y-intercept is 5. This means that the ride lasts 5. kilometers.
Which one is right and why?
Answers
THIS MIGHT NOT BE WHAT YOU ARE LOOKING FOR AND MIGHT NOT BE CORRECT! READ FIRST!
The answer is A. The slope of the line is rise/run = 4/2 = 2.1. This means that each kilometer costs $2.10. The y-intercept is 2.1, which means that the initial fee is $2.10. So the correct statement is: The slope is 2.1. This means that each kilometer costs $2.10.
The other statements are incorrect. The slope is not 5, so each kilometer does not cost $5. The y-intercept is not 5, so the ride does not last 5 kilometers. The y-intercept is the value of the function when the input is 0, which in this case is the initial fee of $2.10.

What is the total surface area of the triangular prism shown?
Answers
Answer: 468 in² B
Step-by-step explanation:
If you flipped the prism so that the triangle part was on the bottom you
SA= LA +2B
where
LA = lateral area = Ph
P(perimeter) = 15+9+12 = 36
h(height) = 10
LA = 36*10 =360
B= 1/2 bh b=9 h=12 I flipped the triangle so 9 would be base
B=1/2(9)(12)
B=54
SA = 360+2(54)
= 468 in²

3x = 45
Divide both sides by 3
3x/3 = 45/3
x = 15
#20 supplementary
2x + 3x + 25 = 180
5x + 25 = 180
5x + 25 - 25 = 180 -25
5x = 155
Divide both sides by 5
5x/5 = 155/5
x = 31

4x - 25 = 75
4x - 25 + 25 = 75 + 25
