Answer:
8.92 * 10^10
Step-by-step explanation:
1. Convert to decimal notation
[tex]8.92*10^6[/tex]
The exponent is 6, making it 10 to the power of 6. As the exponent is positive, the solution is a number greater than the origin or base number. To find our answer, we move the decimal to the right 6 time(s):
8.92 -> [tex]8920000[/tex]
2. Final result
[tex]8920000[/tex]
Move the decimal so there is one non-zero digit to the left of the decimal point. The number of decimal places you move will be the exponent on the 10. If the decimal is being moved to the right, the exponent will be negative. If the decimal is being moved to the left, the exponent will be positive.
8.92 * 10^10

Why learn thisScientific notation, or standard form, makes things easier when working with very small or very big numbers, both of which come up frequently in the fields of science and engineering. It is used in science, for example, to convey the mass of the heavenly bodies: Jupiter’s mass is [tex]1.898*10^{27}[/tex]kg, which is easier to comprehend than writing the number 1,898 followed by 24 zeroes. Scientific notation also makes solving problems that use such high or low numbers more straightforward.

A composite figure is shown.
Diagram shows a composite shape formed by placing a cube before a square prism and a square pyramid next to it that share a common square base. Cube has sides labeled 6 feet. Length of the square prism is 20 feet and height of the pyramid is 4 feet.
What is the surface area for each part of the figure? What is the total surface area of the figure?
The surface area of the pyramid is
square feet.
The surface area of the square prism is
square feet.
The surface area of the cube is
square feet.
The total surface area is
square feet.
The surface area of the pyramid is 60 square feet
The surface area of the square prism is 480 square feet
The surface area of the cube is 180 square feet
The total surface area is 720 square feet
Area of Composite figuresFrom the question, we are to calculate the surface area of each part of the composite figure
For the cubeSurface area of a cube is given by
[tex]S = 6l^{2}[/tex]
Where [tex]l[/tex] is the length of a side
But only have 5 surfaces of the cube are part of the composite figure
∴ Surface area of the cubic part of the figure = [tex]5l^{2}[/tex]
From the given information,
[tex]l = 6 \ feet[/tex]
∴ Surface area of the cubic part of the figure = 5 × 6²
Surface area of the cubic part of the figure= 180 square feet
For the square prismThe surface area of a square prism is given by the formula,
[tex]S = 2l^{2} + 4lh[/tex]
Where [tex]l[/tex] is the length of the sides and
[tex]h[/tex] is the height
But the square surfaces are not part of the surface of the figure
∴ Surface area of the square prism in the figure = [tex]2l^{2} + 4lh - 2l^{2}[/tex]
Surface area of the square prism in the figure = [tex]4lh[/tex]
From the given information,
[tex]l = 6 \ feet[/tex]
[tex]h = 20 \ feet[/tex]
Thus,
Surface area of the square prism part of the figure = 4×6×20
Surface area of the square prism part of the figure = 480 square feet
For the pyramid
The pyramid is a square pyramid
The surface area of a square pyramid is given by
[tex]S = l^{2} + 2l\sqrt{\frac{l^{2} }{4}+h ^{2} }[/tex]
Where [tex]l[/tex] is the base length
and [tex]h[/tex] is the height of the prism
But the square base is not part of the surface of the figure
∴ Surface area of the pyramid part of the figure = [tex]l^{2} + 2l\sqrt{\frac{l^{2} }{4}+h^{2} }\ - ( l^{2})[/tex]
Surface area of the pyramid part of the figure = [tex]2l\sqrt{\frac{l^{2} }{4}+h^{2} }[/tex]
From the given information,
[tex]l = 6 \ feet[/tex]
[tex]h = 4 \ feet[/tex]
∴ Surface area of the pyramid part of the figure = [tex]2(6)\sqrt{\frac{6^{2} }{4}+4^{2} }[/tex]
= [tex]12\sqrt{\frac{36 }{4}+16}[/tex]
= [tex]12\sqrt{9+16 }[/tex]
= [tex]12\sqrt{25}[/tex]
= 12 × 5
= 60 square feet
Hence, the surface area of the pyramid is 60 square feet
Thus,
The total surface area = 180 square feet + 480 square feet + 60 square feet
The total surface area = 720 square feet
Hence, the total surface area is 720 square feet

The statements are:
A. The number of juice boxes will always be greater than 24. B. The number of packages will always be greater than the number of juice boxes. C. The number of juice boxes must be an even number. D. The number of juice boxes will always be 21 more than the number of packages.Number of package starts from 3
Applying the rule: "Multiply by 8.
Number of Juice Boxes = 3×8 = 24
The statement should be the number of juice boxes will always be greater than and equal to 24.
When we multiply even with odd we get an even number.
8 is an even number.
Thus, the statement (C) the number of juice boxes must be an even number is correct.

Which phrase represents the algebraic expression 7p-9?
Answer:
The answer is the sum of three times a number and six, divided by the difference of seven times the number and nine
Step-by-step explanation:
3p = three x a number
7p = seven x a number
3p+6 = sum of three x a number plus six
7p-9 = difference of seven x the number minus nine
(3p+6)/(7p-9) = sum of three times x number plus six, divided by the difference of seven x the number - nine

Monitors manufactured by TSI Electronics have life spans that have a normal distribution with a variance of 4,000,000 and a mean life span of 19,000 hours. If a monitor is selected at random, find the probability that the life span of the monitor will be more than 20,179 hours. Round your answer to four decimal places.
Using the normal distribution, it is found that there is a 0.2776 = 27.76% probability that the life span of the monitor will be more than 20,179 hours.
Normal Probability DistributionThe z-score of a measure X of a normally distributed variable with mean [tex]\mu[/tex] and standard deviation [tex]\sigma[/tex] is given by:
[tex]Z = \frac{X - \mu}{\sigma}[/tex]
The z-score measures how many standard deviations the measure is above or below the mean. Looking at the z-score table, the p-value associated with this z-score is found, which is the percentile of X.The mean and the standard deviation are given, respectively, by:
[tex]\mu = 19000, \sigma = \sqrt{4000000} = 2000[/tex]
The probability that the life span of the monitor will be more than 20,179 hours is one subtracted by the p-value of Z when X = 20179, hence:
[tex]Z = \frac{X - \mu}{\sigma}[/tex]
[tex]Z = \frac{20179 - 19000}{2000}[/tex]
Z = 0.59.
Z = 0.59 has a p-value of 0.7224.
1 - 0.7224 = 0.2776.
0.2776 = 27.76% probability that the life span of the monitor will be more than 20,179 hours.
