Answer:
125
Step-by-step explanation:
5x5=25 25x5=125
5 to the 3rd power (5^3) in standard form is 1.25 * 10^2.
To express 5 to the 3rd power (5^3) in standard form, we'll calculate the result first and then represent it in standard form.
5^3 means multiplying 5 by itself three times:
5^3 = 5 * 5 * 5 = 125.
Now, to express 125 in standard form, we'll use the convention where a number is written as a product of a number between 1 and 10 and a power of 10. This form is used to make large or small numbers more manageable
To do this, we'll write 125 as 1.25 multiplied by a power of 10. Since 125 is equal to 1.25 multiplied by 100 (10^2), we can express it in standard form as:
125 = 1.25 * 10^2.
5 to the 3rd power (5^3) in standard form is 1.25 * 10^2.
In standard form, numbers are expressed as A × 10^n, where A is a number between 1 and 10, and n is an integer representing the power of 10 by which A is multiplied to form the number. In this case, A is 1.25, and n is 2, making it 1.25 × 10^2.
This form simplifies large numbers and is commonly used in mathematics and science for ease of representation.

The graph represents the normal distribution of recorded weights, in pounds, of cats at a veterinary clinic.
A graph shows the horizontal axis numbered 7.5 to x. The vertical axis is unnumbered. The graph shows an upward trend from 8 to 9.5 then a downward trend from 9.5 to 11.
Which weights are within 2 standard deviations of the mean? Select three options.
8.4 lbs
8.9 lbs
9.5 lbs
10.4 lbs
10.9 lbs
Please consider the graph.
We have been given that graph represents the normal distribution of recorded weights, in pounds, of cats at a veterinary clinic. We are asked to choose the weights, which are within 2 standard deviations of the mean.
We can see from our graph that mean of the weights is 9.5 and standard deviation in 0.5.
The data point that would be below two standard deviation is: [tex]9.5-2\times 0.5[/tex] that is [tex]9.5-1=8.5[/tex].
The data point that would be above two standard deviation is: [tex]9.5+2\times 0.5[/tex] that is [tex]9.5+1=10.5[/tex].
Now we need to check the data points that lie within 8.5 and 10.5.
Upon looking at our given choices, we can see that 8.9, 9.5 and 10.4 pounds lie within 2 standard deviation of the mean.
Therefore, 8.9 lbs, 9.5 lbs and 10.4 lbs are correct choices.

Find the distance between (0,10) and (12,1)
A. 12
B. 11
C. 15
D. 16
9514 1404 393
Answer:
C. 15
Step-by-step explanation:
The distance formula can be used for this.
d = √((x2 -x1)² +(y2 -y1)²) = √((12 -0)² +(1 -10)²) = √(144 +81) = √225
d = 15
The distance between the points is 15 units.
_____
Alternate solution
You may recognize that the slope of the line is -3/4, suggesting that this is some multiple of a 3-4-5 right triangle. That multiple is 9/3 = 12/4 = 3, so the hypotenuse of the triangle is 5×3 = 15 units.
Final answer:
The distance between the points (0,10) and (12,1) is 15 units.
Explanation:
The distance between the points (0,10) and (12,1) can be found using the distance formula:
d = sqrt((x2 - x1)^2 + (y2 - y1)^2)
Substituting the given coordinates, the calculation becomes:
d = sqrt((12 - 0)^2 + (1 - 10)^2)
d = sqrt(12^2 + (-9)^2)
d = sqrt(144 + 81)
d = sqrt(225)
d = 15
Therefore, the distance between the two points is 15 units.

N a soccer game, Sally kicks the ball to a teammate who is on the other side of the field. The ball's height h (in feet above the ground), t seconds after Sally kicked it, is modeled by: -2t^2+10t What is the height of the ball at the time it is kicked?
Answer:
At the time that it is kicked, the ball is on the ground, that is, it's height is 0 feet.
Step-by-step explanation:
The height of the ball after t seconds is given by the following equation:
[tex]h(t) = -2t^{2} + 10t[/tex]
What is the height of the ball at the time it is kicked?
The ball is kicked at t = 0.
So we have to find h(0)
[tex]h(0) = -2*0^{2} + 10*0 = 0[/tex]
At the time that it is kicked, the ball is on the ground, that is, it's height is 0 feet.

The mass of the sphere is 800 lbs. Find the density of the sphere to the nearest tenth.
answer choices
7.8 lbs/ft3
21.2 lbs/ft3
28.3 lbs/ft3
7.1 lbs/ft3
Answer:
7.1 lbs / ft^3
Step-by-step explanation:
In this question, we are asked to calculate the density of the sphere in the diagram.
Firstly, to calculate the density , we apply a mathematical formula.
Mathematically, density = mass/volume
We have the mass already from the question but we will need to calculate what the volume is.
Mathematically, the volume of a sphere = 4/3 * pi * r^3
From the diagram, we can see that the radius of the sphere is 3 ft. Plugging this into the equation of the volume of a sphere, we have;
4/3 * 22/7 * 3^3
= 4/3 * 22/7 * 27
= 113.143 ft^3
Now, we substitute the volume into the density equation;
Recall, density = mass/volume
From the question, our mass is 800 lbs and from calculations, volume is 113.143 ft^3
Density = 800 lbs/ 113.143 ft^3 = 7.07 lbs/ ft^3 which is approximately 7.1 lbs/ ft^3

V = (3) squared (14)
V = pi (6) squared (14)
V = pi (3) squared (14)
V = pi (14) squared (6)

========================================================
Work Shown:
V = volume of cylinder
V = (area of circular base)*(height)
V = (pi*r^2)*(h)
V = pi*r^2*h
V = pi*3^2*14 ..... radius 3 is half of diameter 6

What’s the area of this figure?
Answer:
13 sq cm.
Step-by-step explanation:
To find the area of this irregular figure, we will need to find the areas of a rectangle and triangle within this figure.
To find the area of the rectangle, we can simply do:
1 × 4= 4 sq cm.
Now, this is where it gets a little trickier. To find the area of the triangle, we will first need to determine the base and height.
We can see from the diagram that to find the base, we need to subtract:
7-4= 3 cm. This is the base of ONLY the triangle.
To find the height, we will need to do:
5+1= 6 cm. This is the total height of the entirety of the triangle.
We can now use the Triangle Area formula: [tex]\frac{1}{2}[/tex](bh), to calculate the area of the triangle.
[tex]\frac{1}{2}[/tex] (6*3)= 9 sq cm.
Finally, add the areas of the rectangle and triangle together, giving you:
9+4= 13 sq cm.
The five posters made for spirit week are being hung in the front hall. What is the probability the largest poster will be in the center in the next largest will be on its left?
Answer:
1/20 or 0.05
Step-by-step explanation:
Assuming that all five posters are different, the number of ways to randomly place those posters is given by:
[tex]N=5*4*3*2*1 = 120\ ways[/tex]
If we want the largest to be in the center and the next largest to be on its left, two poster will have a set position and only three could be randomized:
[tex]n=3*2*1*1*1=6\ ways[/tex]
Therefore, the probability is:
[tex]P=\frac{n}{N}=\frac{6}{120} =\frac{1}{20} =0.05[/tex]
The probability is 1/20 or 0.05.

The volume (V) of a cone is calculated as
V = [tex]\frac{1}{3}[/tex]πr²h ( r is the radius and h the height )
Here V = 100.48 and r = 4, thus
[tex]\frac{1}{3}[/tex]π × 4²h = 100.48
Multiply both sides by 3 to clear the fraction
3.14 × 16h = 301.44 ( divide both sides by 3.14 × 16 )
h = [tex]\frac{301,44}{3.14(16)}[/tex] = 6 cm

I
Answer:
Step-by-step explanation:
This translates immediately into n/7 = 9. We can isolate (find) n by multiplying both sides of this equation by 7, obtaining n = 63.
Or we could guess and check: if the quotient is 9, we could round that up to 10, obtaining n/7 = 10, or n = approximately 70.
Answer:
Sample Answer: Quotient means the result of division. To use guess and check to solve, you would divide different numbers by 7 until you get 9. The result is 63 ÷ 7 = 9. The quotient of sixty-three and seven is nine.
Step-by-step explanation:
My Answer: Guess and check means you guess different numbers until you get the correct answer. For example, let’s start with the number 60. You will get a decimal if you do that problem, so that’s no the answer. Then you keep guessing. The correct answer is 63. 63 divided by 7 is 9.

Option A and E are the correct answer
The only expression equivalent to 12x - 6 is 6(2x-1). Hence first option is correct.
The question asks which expressions are equivalent to 12x - 6. Let's evaluate each given option:
6(2x-1): Distributing the 6 gives 12x - 6, which is equivalent to the original expression.
-6(2x+1): Distributing the -6 gives -12x - 6, which is not equivalent to the original expression.
-6(2x-1): Distributing the -6 gives -12x + 6, which is not equivalent to the original expression.
-6x(2x-1): This expression cannot be simplified to the form of a single term in x and a constant; thus, it's not equivalent.
6x(2-1): Simplifying inside the parentheses first gives 6x, which is not equivalent to the original expression.
Therefore, the only expression equivalent to 12x - 6 is 6(2x-1).

Two similar cylinders have surface areas of 24 cm2 and 54 cm2. The volume of the smaller cylinder is 16 cm2.
What is the volume of the larger cylinder?
36 cm2
46 cm2
48 cm2
54 cm2
Answer:
54pie cm2 is the correct answer
Final answer:
The volume of the larger cylinder is 36 cm².
Explanation:
To find the volume of the larger cylinder, we need to compare the surface areas of the two cylinders. Let's assume that the surface area and volume of the smaller cylinder are represented by SA1 and V1 respectively, and the surface area and volume of the larger cylinder are represented by SA2 and V2 respectively.
Since the cylinders are similar, their surface areas and volumes are proportional. Therefore, we can set up the following ratio: SA1 / SA2 = V1 / V2. Plugging in the given values, we get: 24 / 54 = 16 / V2. Solving for V2, we find that the volume of the larger cylinder is 36 cm².
