A=1/2 πr²
Solve for π

Answer:

b = 0

Step-by-step explanation:

The modulus of a + bi is

| a + bi | = [tex]\sqrt{a^2+b^2}[/tex] , then

[tex]\sqrt{a^2+b^2}[/tex] = a ( square both sides )

a² + b² = a² ( subtract a² from both sides )

b² = 0 ⇒ b = 0

Answer:

14 1/8 feet by 18 3/8.

Step-by-step explanation:

I took 1 5/8 feet and added it to both...

The new dimensions of the garden will be 18 3/8 feet and 14 1/8 feet.

It is a polygon with four sides. The total interior angle is 360 degrees. A rectangle's opposite sides are parallel and equal, and each angle is 90 degrees. Its diagonals are all the same length and intersect in the center.

The dimensions of a rectangular garden are 12 1/2 feet by 16 3/4 feet. If 1 5/8 feet is added to all the sides.

Then the length will be

L = 16  3/4 + 1  5/8

L = 17  (3/4 + 5/8)

L = 17  11/8

L = 18  3/8 feet

Then the width will be

W = 12  1/2 + 1  5/8

W = 13  (1/2 + 5/8)

W = 13  9/8

W = 14  1/8 feet

The new dimensions of the garden will be 18 3/8 feet and 14 1/8 feet.

Answer:

The answer to that is a. 7/20

The product of [tex]\frac{7}{10} \times \frac{3}{6}[/tex] will be 7/20.

Hence option A is correct.

Multiplication : It is one of the operator in mathematics among addition , subtraction and division.

Given, that product of 7/10 × 3/6

Multiplication of fractional terms:

[tex]\frac{a}{b} \times \frac{c}{d}[/tex] [tex]= a\times c/b\times d[/tex]

Apply multiplication of fractional terms

[tex]\frac{7}{10} \times \frac{3}{6} = 7\times 3 / 10 \times 6\\\\= \frac{21}{60}\\ \\= \frac{7}{20}[/tex]

   To solve this problem use the property of similar triangles,

 "Corresponding sides of the similar triangles are proportional"

By using this property, height of the parasailer is 160 feet.

From the figure attached,

Let the height (PQ) of the parasailer = x ft

Height of the parasailer AB = 25 ft.

And the length of the rope AC = 2.5 ft.

Since, both the triangles ΔABC and ΔPQR are the similar triangles, their corresponding sides will be proportional.

[tex]\frac{AB}{PQ}=\frac{AC}{PR}[/tex]

[tex]\frac{2}{x} =\frac{2.5}{200}[/tex]

[tex]x=\frac{200\times 2}{2.5}[/tex]

Answer:

The coordinates of point P are [tex]\left(\dfrac{-1}{10},\dfrac{-37}{10}\right)[/tex]

Step-by-step explanation:

The Coordinates of point A are (-4,-7), and the coordinates of point B are (9,4).

Let us assume that the coordinates of point [tex]\dfrac{3}{10}[/tex] of the way from A to B are P(x,y).

Now,

Applying the section formula,

[tex]x=\dfrac{3 \times 9+7 \times -4}{3+7}\\x=\dfrac{27 -28}{10}\\x=\dfrac{-1}{10}[/tex]

[tex]y=\dfrac{3 \times 4+7 \times -7}{3+7}\\y=\dfrac{12 -49}{10}\\y=\dfrac{-37}{10}[/tex]

Therefore, the coordinates of point P are [tex]\left(\dfrac{-1}{10},\dfrac{-37}{10}\right)[/tex]

Answer:

Loss Amount: 175; Price: 3325

Step-by-step explanation:

You can multiply 3500 by 0.05 (which is 5% in decimal) to find how much is the loss. Then, you subtract the loss from the base price to find the new price.

Answer:

Loss =175, sold = 3325

Step-by-step explanation:

He bough at 3500

So 100 percent is 3500

And they said he had a 5% loss

So in other words, he sold it to Alex at 95% of the price he bought

So

3500 x 95%

3500 x 95/100

=3325

This is the price when Hitler sold it to alex

Now how much did Hitler lose?

3500 - 3325

=175

Hello :D

Let's form an equation:

x/5 = 27

Let's form another equation:

(x+y)/7 = 34

Rearrange equation one so it is x = 27 x 5 = 135

Now we can substitute this value into equation 2:

(135 + y)/7 = 34

135 + y = 238

y = 238 - 135

y = 103

Answer is 103

Answer:

103 christmas trees.

Step-by-step explanation:

total trees sold in the first five days:

Step-by-step explanation:

We can use a proportion to solve

18 dollars       x dollars    

-------------  = ---------------

4 tickets        9 tickets

Using cross products

18 *9 = 4x

162 = 4x

Divide by 4

162/4 = 4x/4

40.50 =x

Answer:

40.5

Step-by-step explanation:

This is divied 18 and 4

= 4.5

Then 4.5*9=40.5

You have three cases, if x is strictly greater than 3 (which is our case since x = 6), the value of the function is √(x+3).

so f(6) = √(6+3) = √9 = √(3*3) = √(3²) = 3

C = (4 x 16) - 6

Step-by-step explanation:

There is 4 packages. Packages can hold many cookies in this case 16 cookies can be placed inside 1 package.

The total number of cookies can be calculated:

16 x 4 (4 packages altogether with 16 cookies in each package)

They did not eat 6 cookies so 6 cookies are leftover or remaining:

(16 x 4) - 6 (subtract 6 because they did not eat it, we want what they already ate - takeaway 6)
