Answer:

40

Step-by-step explanation:

The sample answer for edmentum is: The first factor of the mass of an average grain of rock salt is 40 times the first factor of the mass of an average grain of table salt. So, the mass of an average grain of rock salt is 40 times greater than the mass of an average grain of table salt.

The mass of an average grain of rock sand is 43.4 times larger than the mass of an average grain of table salt

Scale factor is used to compare the size of two objects. Mathematically, we can write -

{K} = S{O1}/S{O2}

13 mg

Given is to compare the mass of an average grain of rock sand than the mass of an average grain of table salt​.

The mass of an average grain of rock sand is : 13 mg

The mass of an average grain of table salt is : 0.3 mg

So, we can write that -

{K} = M{rock sand}/M{table salt}

{K} = 13/0.3

{K} = 130/3

{K} = 43.4

So, it can be concluded that the mass of an average grain of rock sand is 43.4 times larger than the mass of an average grain of table salt.

Therefore, the mass of an average grain of rock sand is 43.4 times larger than the mass of an average grain of table salt.

x=4+7i and x=4-7i

Step-by-step explanation:

Rewrite the given quadratic equation by completing the square.

x^2-8x=-65

x^2-8x+16=-65+16

x^2-8x+16=-49

(x-4)^2=-49

Now, solve the equation by applying the square root property and isolating x.

(x-4)^2=-49

√(x-4)^2 = √-49

x-4=+7i

x=4+7i

So, the solutions to the given quadratic equation are x+4+7i and x=4-7i.

Answer:

20%

Step-by-step explanation:

2-1.6=0.4

0.4/2x 100

40/200=1/5 or 20%

Last year the chess club had 30 members. This year the club has 24 members.

Last year, the chess club had 30 members. This year, the club has 24 members. Since this year had less than last year ( 30 > 24), the percent will be decreasing.

To find the percent decrease, you have to use the following formula.

[tex]\frac{Difference}{Original} \times 100[/tex]

Difference refers to the difference between the two numbers, 24 and 30. The difference between 24 and 30 is 6. Original refers to the original number, which is last year's amount of members in the chess group. Therefore, original = 30.

Substitute the numbers into the formula.

[tex]\frac{Difference}{Original} =\frac{6}{30} =0.2[/tex]

To convert the decimal to a fraction, multiply the decimal by 100.

[tex]0.2 \times 100 = 20 \%[/tex]

The answer is the number of chess members decreased by 20%.

____

Since I started off by identifying whether it was decreasing or increasing, I did the work a bit differently. When finding the difference, you would usually subtract 30 from 24, which results in -6. Above I used 6, but if you used -6, you would end up with a result of -20%, which means it decreased by 20%. They bot end up with the same result, but you don't always have to first identify whether it's decreasing or increasing.

Answer:

Decreasing

Step-by-step explanation:

The percentages are decreasing because one year the club had 30 members and the present year has 24 members that decreased by 6!

Answer:

D; $223.74

Step-by-step explanation:

The amount of bill before tax = $193.75

Percentage of tax added by the waiter = 4%

Amount of tax added by the waiter = (4/100) * 193.75 dollars

                                                       = 775/100 dollars

                                                       = 7.75 dollars

Total bill after tax = (193.75 + 7.75) dollars

                           = 201.50 dollars

Percentage of tips that Luca wants to give = 16%

Amount of tips that Luca wants to give = (16/100) * 201.50 dollars

                                                             = 32,24 dollars

The total amount that Luca needs to pay = (201.50 + 32.24) dollars

                                                                = 233.74 dollars

Answer:

My age is 38 years old

My son is 11 years old

Step-by-step explanation:

Represent my current age with x and my son's current age with y

Two years ago;

[tex]x - 2 = 4 * (y - 2)[/tex]

Eight years ago:

[tex]x - 8 = 10 * (y - 8)[/tex]

Simplify both expressions

[tex]x - 2 = 4 * (y - 2)[/tex]

[tex]x - 2 = 4y - 8[/tex]

Add 2 to both sides

[tex]x - 2 +2= 4y - 8 + 2[/tex]

[tex]x = 4y - 6[/tex]

Substitute 4y - 6 in the second equation

[tex]x - 8 = 10 * (y - 8)[/tex]

[tex]4y - 6 - 8 = 10 * (y - 8)[/tex]

[tex]4y - 14 = 10y - 80[/tex]

Collect Like Terms

[tex]4y - 10y = 14 - 80[/tex]

[tex]-6y = -66[/tex]

Divide through by -6

[tex]y = 11[/tex]

Substitute 11 for y in [tex]x = 4y - 6[/tex]

[tex]x = 4 * 11 - 6[/tex]

[tex]x = 44 - 6[/tex]
