how do you rewrite the formula to solve for r?

Answers

Answer:

The answer is C.

The steps are :

[tex] {T}^{2} = ( \frac{4 {\pi}^{2} }{GM} ) \times {r}^{3} [/tex]

[tex] {T}^{2} \div ( \frac{4 {\pi}^{2} }{GM}) = {r}^{3} [/tex]

George had $6,000 in a savings account earning simple interest at a rate of 5% per year. At the end of the year, George paid 25% in taxes on his interest. How much money did George earn in interest that year after paying taxes?

Answers

Answer:

$225

Step-by-step explanation:

Given that:

Principal = $6,000

Interest rate = 5%

Time = 1 year

Taxes paid = 25% on the interest earned

To find:

Money earned after paying taxes ?

Solution:

First of all, let us calculate the total interest earned:

Formula for Simple Interest is given as:

[tex]SI =\dfrac{PRT}{100}[/tex]

Where P is the principal

R is the rate of interest

T is the time taken

Putting the given values:

[tex]SI =\dfrac{6000 \times 5\times 1}{100} =\$300[/tex]

Now, it is given that 25% of the interest earned is given as taxes.

Taxes paid = 25% of $300

[tex]\Rightarrow \dfrac{25}{100} \times 300 =\$75[/tex]

Therefore, the money earned = Interest earned - Taxes paid

The money earned = $300 - $75 = $225

A teacher is making a history test composed of the same number of multiple choice questions as short answer questions she estimates it will take students an average of two minutes to complete each multiple-choice questions and an average of 3.5 minutes to complete each short answer questions, n,quality to determine how many questions and the teacher can include if the test must take students less than 45 minutes to complete

Answers

Answer:

8 questions each for short answer questions and 8 questions of Multiple Choice Questions type.

A total of 16 questions.

Step-by-step explanation:

Given:

The number of multiple choice questions and number of short answer type questions are same.

Let it be equal to [tex]x[/tex].

Average Time taken to attempt multiple choice question = 2 minutes

Total time taken to attempt multiple choice question = 2[tex]\times x[/tex] minutes

Average Time taken to attempt short answer type question = 3.5 minutes

Total Time taken to attempt short answer type question = 3.5[tex]\times x[/tex]

Total time for test should be less than 45 minutes.

Variable y varies directly with variable x. If x = 12, then y = 3. What is the value of y
when x = 8?

Answers

Answer:

y = 2

Step-by-step explanation:

To find the value of y when x = 8 we must first find the relationship between the two variables.

The statement

y varies directly with variable x is written as

y = kx

where k is the constant of proportionality

when

x = 12

y = 3

Substitute the values into the above formula and solve for k

That's

3 = 12k

Divide both sides by 12

[tex]k = \frac{1}{4} [/tex]

So the formula for the variation is

[tex]y = \frac{1}{4} x[/tex]

when

x = 8

[tex]y = \frac{1}{4} \times 8[/tex]

we have the final answer as

y = 2

Three times the sum of half a number and 7 is 36

Answers

Answer:

your answer is 19.34

Step-by-step explanation:

let the number be x

half a number = ½ x

three times means multiplied by three

so,

3( ½ x) + 7 = 36

3( ½ x) = 36 - 7

3( ½ x) = 29

½ x = 29/3

½ x = 9.67...

x = 9.67 × 2           (when we moved  ½ on the other side of the equal sign it                                      ›                               turns into 2/1 )

Item 15 Question 1 Write and solve an equation to answer the question. The perimeter of the Norwegian flag is 190 inches. What are the dimensions of the flag? Equation: =190 y= Question 2 Label the dimensions of the flag in inches.

Answers

Answer:

40 inches by 55 inches.

Step-by-step explanation:

The question lacks the required diagram. Find the diagram in the attachment.

The flag is rectangular in nature and the formula for calculating the perimeter of a rectangle is P = 2(L+W) where;

L is the length of the flag

W is the width of the flag

From the diagram, L = y and W = 11y/8

Since the perimeter = 190 inches, we will substitute the given parameters into the formula and firs calculate the value of y.

190 = 2(y+11y/8)

190 = 2y + 11y/4

multiply through by 4

760 = 8y+11y

760 = 19y

y = 760/19

y = 40

The length of the flag is 40 inches and the Width of the flag is 11(40)/8 = 55inches.

Hence, the dimensions of the flag in inches is 40 inches by 55 inches.

Johnny’s vegetable garden is rectangular. The length of the garden is 2x-1 and the width of the garden is 3x+2. Find the Perimeter and Area of the garden.

Answers

Answer:

[tex] \boxed{\sf Perimeter \: of \: rectangular \: garden = 10x + 2} [/tex]

[tex] \boxed{\sf Area \: of \: rectangular \: garden = 6x^2 + x - 2} [/tex]

Given:

Length of rectangular garden = 2x - 1

Width of rectangular garden = 3x + 2

Step-by-step explanation:

[tex] \sf Perimeter \: of \: rectangular \: garden = 2(Length + Width)[/tex]

[tex] \sf = 2((2x - 1) + (3x + 2))[/tex]

Grouping like terms:

[tex] \sf = 2((2x + 3x) + (2 - 1))[/tex]

2x + 3x = 5x:

[tex] \sf = 2(5x + (2 - 1))[/tex]

2 - 1 = 1:

[tex] \sf = 2(5x + 1)[/tex]

[tex] \sf = (2 \times 5x) + (2 \times 1)[/tex]

2 × 5x = 10x:

[tex] \sf = 10x + (2 \times 1)[/tex]

2 × 1 = 2:

[tex] \sf = 10x + 2[/tex]

[tex] \therefore[/tex]

Perimeter of rectangular garden = 10x + 2

[tex] \sf Area \: of \: rectangular \: garden = Length \times Width[/tex]

[tex] \sf = (2x - 1)(3x + 2)[/tex]

[tex] \sf = 2x(3x + 2) - 1(3x + 2)[/tex]

[tex] \sf = (2x \times 3x) + (2x \times 2) - (1 + 3x) - (1 \times 2)[/tex]

2x × 3x = 6x²:

[tex] \sf = 6 {x}^{2} + (2x \times 2) - (1 + 3x) - (1 \times 2)[/tex]

2x × 2 = 4x:

[tex] \sf = 6 {x}^{2} + 4x - (1 + 3x) - (1 \times 2)[/tex]

1 × 3x = 3x:

[tex] \sf = 6 {x}^{2} + 4x - 3x - (1 \times 2)[/tex]

1 × 2 = 2:

[tex] \sf = 6 {x}^{2} + (4x - 3x) - 2[/tex]

4x - 3x = x:

[tex] \sf = 6 {x}^{2} + x - 2[/tex]

[tex] \therefore[/tex]

Area of rectangular garden = 6x² + x - 2

Answer:

Perimeter = 10x+2 m

Area = 6x²+x-2 m²

Step-by-step explanation:

Length of garden (l) = 2x-1

width or breadth of garden ( b) = 3x+2

Now,

Perimeter of the garden (p) = 2( l + b)

= 2 ( 2x-1 + 3x+2 )

= 2 ( 5x + 1 )

= 10x+2 m. ( Answer )

Again,

Area of garden (a) = l * b

= ( 2x-1 ) ( 3x+2 )

= 2x ( 3x+2 ) -1 ( 3x+2 )

= 6x² + 4x - 3x - 2

= 6x²+x-2 m². ( Answer )

Given: DC =6x, and DA =4x+18 EB =4y-12, and ED =y+17 Y Find y. Then find ED, DB and EB.

Answers

Complete Question:

Given:

(1) DC = 6x, and DA = 4x + 18, find the value of x. Then find AD, DC, and AC

(2) EB = 4y - 12, and ED = y + 17. Find y. Then find ED, DB and EB.

Answer:

x = 9, AD = 54, DC = 54, AC = 108

y = 23, ED = 40, DB = 40, EB = 80

Step-by-step explanation:

The diagram for this question has been attached to this response.

(1) From the diagram, it can be observed that;

(a) DC and DA have equal lengths. i.e

=> DC = DA             ---------------------(i)                  

(b) AC = DA + DC    --------------------(ii)

But;

DC = 6x

DA = 4x + 18

Substitute the values of DC and DA into equation (i) as follows;

6x = 4x + 18          [Solve for x]

6x - 4x = 18

2x = 18

x = 9

Since x = 9, then

DC = 6x = 6(9) = 54

DA = 4x + 18 = 4(9) + 18 = 54

Therefore

DC = 54

AD = DA = 54

AC = 54 + 54 = 108       [using equation (ii)]

(2) Also, from the diagram, it can be observed that;

(a) ED and DB have equal lengths. i.e

=> ED = DB             ---------------------(iii)                  

(b) EB = ED + DB    --------------------(iv)

=>EB = ED + ED        [since ED = DB]

=>EB = 2ED             ------------------(v)

But;

EB = 4y - 12

ED = y + 17

Substitute the values of EB and ED into equation (v) as follows;

4y - 12 = 2(y + 17)          [Solve for y]

4y - 12 = 2y + 34

4y - 2y = 34 + 12

2y = 46

y = 46 / 2

y = 23

Since y = 23, then

EB = 4y - 12 = 4(23) - 12 = 80

ED = y + 17 = 23 + 17 = 40

Therefore

EB = 80

ED = DB = 40

Answer:

x = 9, AD = 54, DC = 54, AC = 108

y = 23, ED = 40, DB = 40, EB = 80
