Answer:

Answer. Multiplying by 3/4 is the same as multiplying by 75%.

Step-by-step explanation:

Last option: Multiplying by 3/4 is the same as multiplying by 75%, because:

3/4=0.75 and

75%=75/100=0.75

then 3/4=0.75=75%

Step-by-step explanation:

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:

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

The question is "Does the amount of money just double or do the previous amounts add to the present amount?"

I think it just doubles. Not only that, but she can't spend any of it until night 22 is reached.

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.

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

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:

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:

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.

Step-by-step explanation:

Let the slope of one line be 's' , then according to the given condition that the  slope of second line is negative reciprocal of the first , We obtain the slope of the second line as [tex]\frac{-1}{s}[/tex].

So, the product of both the slopes is given by [tex]s\cdot \frac{-1}{s}=-1[/tex]

This shows that whatever the slopes may be if they are negative reciprocal of each other then their product will always be -1

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].

1.74/-0.06 is -29.
