Step-by-step explanation:
A specific distance is approximately 63,500,00 mi. A fly is about 0.18 in. long ???
A) what is the distance written in scientific notation
B) what is the length of a fly written in scientific notation
C) change the distance to inches it would be 5.04×10 to the power of nine if we lined up the flies how many would it take to reach the distance in standard form and scientific notation.
Answer:
Step-by-step explanation:
a) Given that a specific distance is approximately 6350000 miles.
To write this in scientific notation. We know that for writing in scientific notation we must writte the given number as a positive number less than 10 x product of powers of n.
Hence this number
6350000 = 6.35 x1000000 = [tex]6.35x10^6[/tex] miles
b) Length of a fly = 0.18 inches.
To write this in scientific notation. We know that for writing in scientific notation we must writte the given number as a positive number less than 10 x product of powers of n.
so 0.18 = 1.8([tex]1.8(10^{-1}[/tex]
c) Given that distance = 5.04x10^9 inches
To line up number of flies required
= [tex]\frac{5.04x10^9}{0.18} = \frac{504x10^9}{18}=28(10^9)\\Answer is\\28(10^9)[/tex]
In this mathematical problem, the distance of 63,500,000 miles is written in scientific notation as 6.35 x 10^7. The length of a fly, 0.18 inches, is expressed in scientific notation as 1.8 x 10^-1. To find the number of flies to cover the distance, the distance is first converted to inches (5.04 x 10^9), which when divided by the length of a fly results in 2.8 x 10^10, meaning approximately 28,000,000,000 flies would be needed.
Explanation:The student's question involves the use of scientific notation and unit conversion in Mathematics.
Firstly, the distance given as approximately 63,500,000 miles can be written in scientific notation as 6.35 x 10^7 miles. The number is changed to a number between 1 and 10 by moving the decimal point 7 places to the left, hence the exponent 7. Secondly, the length of the fly given as 0.18 inches can be written in scientific notation as 1.8 x 10^-1 inches. The decimal point is moved 1 place to the right resulting in an exponent of -1. Lastly, to find out how many flies it would take to reach the distance, we first need to convert the distance from miles to inches. It is given that the conversion is approximately 5.04 x 10^9 inches. So, if we divide this by the length of a fly, i.e., 1.8 x 10^-1 inches, we would arrive at approximately 2.8 x 10^10 flies in both standard form and scientific notation. That is, it would take about 28,000,000,000 flies to reach the mentioned distance. Learn more about Scientific Notation and Unit Conversion here:

Diego has 49 square inch tiles. He wants to use to make a square mosaic. How long can each side of the mosaic be?
Answer:
side of the mosaic = 7 inches
Step-by-step explanation:
Diego has 49 square inch tiles. He wants to use to make a square mosaic.
Area of the tile = 49 square inches
We know , area of the square = s^2
where 's' is the side of the square
[tex]Area = s^2[/tex]
Plug in 49 for area and solve for 's'
[tex]49 = s^2[/tex]
Take square root on both sides
s= 7
side of the square = 7 inches
Diego can make a square mosaic where each side is 7 inches using his 49 square-inch tiles. This is found by calculating the square root of the total area.
Explanation:The subject of this question is Mathematics, specifically dealing with square roots and area calculations. Diego has 49 square inch tiles and wants to make a square mosaic. Since a square has equal sides, the length of each side of the mosaic will be the square root of the total area. The total area of the tiles is 49 square inches. The square root of 49 is 7. Therefore, each side of Diego's mosaic will be 7 inches in length. This conclusion is reached by understanding how the area of a square works. The area of a square can be calculated by multiplying the length of one side by the length of another side. When we know the total area, we can find the length of one side by taking the square root.

Given: line segment AB is 10 inches long.
Find the length of A'B' if AB is dilated to form A'B' with a scale factor of 2.
A) 1/2 inches
B) 5 inches
C)10 inches
D)20 inches
Answer:
D or 20
Step-by-step explanation:
If the scale factor is 2 then you take the original number, 10, and multiply it by 2.
10*2=20
Answer:
Option D). 20 inches
Step-by-step explanation:
Length of AB which is of length = 10 inches.
If the length of AB is dilated to form A'B' with a scale factor of 2, then we have to find the length of A'B'
Since we know the formula of dilation as
New dimension = Scale factor × Old dimension
So A'B' = Scale factor × AB
A'B' = 2× 10 = 20 Inches
Option D). 20 inches is the solution.
Given the equation: y−6=1/2(x+2) in point slope form, rewrite the equation into standard form. Show your work for full credit.
Answer:
x - 2y = - 14
Step-by-step explanation:
the equation of a line in standard form is
Ax + By = C ( A is a positive integer and B, C are integers )
given y - 6 = [tex]\frac{1}{2}[/tex](x + 2)
multiply all terms by 2 to eliminate the fraction
2y - 12 = x + 2 ( subtract 2 from both sides )
2y - 14 = x ( subtract 2y from both sides )
- 14 = x - 2y, hence
x - 2y = - 14 ← in standard form

Factor the expression P^4+3p^3-10p^2
Answer:
[tex]p^2(p+5)(p-2)[/tex]
Step-by-step explanation:
To begin factoring the expression [tex]p^4+3p^3-10p^2[/tex], we use the GCF or greatest common factor. The greatest common factor is the greatest number that will divide into two or more values. We start to find it by factoring each term:
[tex]p^4=p*p*p*p[/tex]
[tex]3p^3: 3*p*p*p[/tex]
[tex]-10p^2: -10*p*p[/tex]
Remember -10 can factor into smaller numbers but since it doesn't have common factors with the others, we've chosen to leave it as -10.
We notice the only common factors bare p*p or [tex]p^2[/tex].
We write in the form p^2(____+_____+_____). We find the inside of the parenthesis by dividing each term by p^2.
[tex]\frac{p^4}{p^2} =p^2[/tex]
[tex]\frac{3p^3}{p^2} =3p[/tex]
[tex]\frac{-10p^2}{p^2}=-10[/tex]
[tex]p^2(p^2+3p-10)[/tex].
We are not finished yet. We have a trinomial (3 terms) which also factors. We factor by splitting the middle term 3p into factors of -10 which add to 3.
--10 = 5 * -2
3p= 5p +-2p
We write [tex]p^2(p+5)(p-2)[/tex].

word form of 16.0215
Answer: sixteen and two-hundred fifteen ten thousandths
You'd have to correspond the numbers to words and associate the period with and
Answer: Sixteen and two hundred fifteen ten-thousandths
We read off "16" as normal. Nothing too special about it.
The same goes for the 0215 which is really just 215, even though this part is after the decimal point. However, because it is after the decimal point, we tack on a "ten thousandths" to indicate it's a fractional non-whole portion
Note: if you change the 0 to something like a 3, then we would have 3215 which is less than ten-thousand. This might help you remember that four decimal spots out is the ten-thousandth place value.
another note: the "and" mentioned in the answer is a key word that indicates "decimal point". Only use it for decimal points. Do not use it for a number like "215". In other words, don't say "two hundred and fifteen" because that might seem like you are trying to say 2.15 or something along those lines.

What is the equation of a line with a slope of 7 and a point (1, 8) on the line?
Express the equation in the form of y = mx + b, where m is the slope and b is the y-intercept.
Enter your answer in the box.
Answer:
y = 7x + 1
Step-by-step explanation:
If the slope and coordinates have already been given, you can plug the values into the following equation of a line:
y - y1 = m(x - x1)
Where y1 is the y coordinate, so in this case 8,
x1 is the x coordinate which is 1
m is the slope, so 7:
y - 8 = 7(x - 1)
Expand the brackets:
y - 8 = 7x - 7
To isolate the y, we need to move the -8 over to the other side making it a positive 8:
y = 7x - 7 + 8
y = 7x + 1
So the equation of the line is y = 7x + 1

Surf the internet percentage is 9
Probability (surf the internet) =[tex]\frac{9}{100}[/tex]
the probability (reading books or surf the internet)= P(reading books) + P(surf the internet)
probability (reading or surf)= [tex]\frac{22}{100} +\frac{9}{100}[/tex]
= [tex]\frac{31}{100} [/tex]
Answer:
Answer is [tex]\frac{31}{100}[/tex]
Step-by-step explanation:

Reading books percentage is 22
hence we can write probability as
Probability (reading books) = [tex]\frac{22}{100}[/tex]
percentage of surfing internet is= 9
Probability of surfing internet is =[tex]\frac{09}{100}[/tex]
the probability (reading books or surf the internet)= P(reading books) + P(surf the internet)
probability (reading or surf)= [tex]\frac{22}{100}[/tex]+[tex]\frac{09}{100}[/tex]
=[tex]\frac{31}{100}[/tex]
