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.

Answer:

31/100

Step-by-step explanation:

From the given table

Reading books percentage is 22

so Probability (reading books) = [tex]\frac{22}{100}[/tex]

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:

values given in table

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]

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.

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.

well first reduce it which would be 5/3 since the greatest common denominator would be 4. Then put 3 in the 5 which goes only once and 2 is left over. Keep the threeas the denominator instead of the numerator.

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

16^1/2 is the same thing as 2√16.

Simply multiply the result of √16 by 2 to get the answer.

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.

Answer:

Centimeters and kilometers are used to measure length

Step-by-step explanation:

Centimeters and kilometers are related to each other.

We can represents centimeters in  kilometers and kilometers in centimeters

Short form

The short form of kilometers = km

The short form of centimeters = cm

1 km = 100000 cm

1 cm = 1/100000  km

We can also represent both  in terms of meters

1 m = = 100 cm

1000 m = 1 km

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].

x = 8.5 + 2.5y answer one can’t figure out answer two. Sorry

Answer:

{x = 1 , y = 3

Step-by-step explanation:

Solve the following system: using elimination:

{2 x + 5 y = 17 | (equation 1)

{6 x - 5 y = -9 | (equation 2)

Swap equation 1 with equation 2:

{6 x - 5 y = -9 | (equation 1)

{2 x + 5 y = 17 | (equation 2)

Subtract 1/3 × (equation 1) from equation 2:

{6 x - 5 y = -9 | (equation 1)

{0 x+(20 y)/3 = 20 | (equation 2)

Multiply equation 2 by 3/20:

{6 x - 5 y = -9 | (equation 1)

{0 x+y = 3 | (equation 2)

Add 5 × (equation 2) to equation 1:

{6 x+0 y = 6 | (equation 1)

{0 x+y = 3 | (equation 2)

Divide equation 1 by 6:

{x+0 y = 1 | (equation 1)

{0 x+y = 3 | (equation 2)

Collect results:

Answer:  {x = 1 , y = 3

Answer: 4 cups of milk

=============================

Work Shown:

2 & 1/2 = 2 + 1/2 = 2+0.5 = 2.5

2.5 cups of milk makes 5 servings

x cups of milk makes 8 servings

Divide the cups of milk over the servings to get this proportion

2.5/5 = x/8

Cross multiply and solve for x

2.5/5 = x/8

2.5*8 = 5*x

20 = 5*x

5*x = 20

x = 20/5

x = 4

You need 4 cups of milk to make 8 servings

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

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.

The student's question involves the use of scientific notation and unit conversion in Mathematics.
