Answer: 9π/2

Step-by-step explanation:

A semicircle is half of a circle. Therefore, you must divide the area by 2.

[tex]A=\frac{\pi r^2 }{2}[/tex]

Since we know the radius, we can directly plug it into the formula.

[tex]A=\frac{\pi (3)^2}{2} =\frac{9\pi }{2}[/tex]

Since the problem stated to give the answer in terms of π, 9π/2 is our answer.

Answer:

[tex]\frac{9\pi }{2}[/tex] cm²

Step-by-step explanation:

The area of a semicircle can be expressed by the formula [tex]\frac{\pi r^{2} }{2} = A[/tex].

When you plug in the radius, you get [tex]\frac{\pi 3^{2} }{2} = \frac{\pi 9}{2} = \frac{9\pi }{2}[/tex].

Answer:

[tex](x^{-3} )^{2}[/tex]

[tex]x^6 x^{-12}[/tex]

Step-by-step explanation:

[tex](x^{3} x^{-6} )^{2}[/tex] is the expression given to be solved.

First of all let us have a look at 3 formulas:

[tex]1.\ p^a \times p^b = p^{(a+b)}\\2.\ (p^a \times q^b)^c = (p^{a})^c \times (q^{b})^c\\3.\ (p^a)^b = p^{a\times b}[/tex]

Both the formula can be applied to the expression([tex](x^{3} x^{-6} )^{2}[/tex]) during the first step while solving it.

Applying formula (1):

[tex](x^{3} x^{-6} )^{2}[/tex]

Comparing the terms of [tex](x^{3} x^{-6} )[/tex] with [tex]p^a \times p^b[/tex]

[tex]p=x, a =3, b=-6[/tex]

[tex]\Rightarrow x^{3+(-6)}\\\Rightarrow x^{3-6}\\\Rightarrow x^{-3}[/tex]

So, [tex](x^{3} x^{-6} )^{2}[/tex] is reduced to [tex](x^{-3} )^{2}[/tex]

Applying formula (2):

Comparing the terms of [tex](x^{3} x^{-6} )^{2}[/tex] with [tex](p^a \times q^b)^c[/tex]

[tex]p=q=x, a =3, b=-6, c=2[/tex]

[tex]\Rightarrow (x^{3})^2\times (x^{-6})^2\\\text{Applying Formula (3)}\\x^6 x^{-12}[/tex]

So, [tex](x^{3} x^{-6} )^{2}[/tex] is reduced to [tex]x^6 x^{-12}[/tex].

So, the answers can be:

[tex](x^{-3} )^{2}[/tex]

[tex]x^6 x^{-12}[/tex]

Answer:

$83.2

Step-by-step explanation:

price= $128

sale discount= 35%

sale price= $128- 35%= $128*0.65= $83.2

Answer:

83.2$

Step-by-step explanation:

Given:

A docking station for an iPod cost 128$.

The discount percent is 35%.

Solve for:

The sale price of docking station.

Solution:

The amount of discounted price (DP) could be calculated by formula:

DP = original price x discount percent

     = 128 x 35%

     = 128 x 35/100

     = 44.8$

=> The sale price (P) is:

P = original price - discounted price

  = 128 - 44.8

  = 83.2$

The inequality that can be used to figure out how many cases Sandra is working on is: [tex]x + 8 > 29[/tex]

Step-by-step explanation:

She is working on "x" cases, then she adds 8 more to that number, therefore it is "x + 8" and we also know that the total number of cases she's working is more than 29, in other words, it is greater than 29. With this in mind we can create the following inequality:

[tex]x + 8 > 29[/tex]

The inequality that can be used to figure out how many cases Sandra is working on is: [tex]x + 8 > 29[/tex]

Answer:

7.2

Step-by-step explanation:

The radius of the circle is 14.

The length of the chord is 12.

Half the length of the chord and radius form a right angled triangle as shown in the diagram below.

We need to find one of the sides of the triangle, d in the diagram.

Using Pythagoras rule:

[tex]14^2 = 12^2 + d^2\\\\196 = 144 + d^2\\\\d^2 = 196 - 144 = 52\\\\d = \sqrt{52} = 7.2[/tex]

The distance between the chord and the center of the circle is 7.2

Answer: 4sqrt10

Step-by-step explanation: The Chord is 12 so half the chord is 6 so the base is 6 and the radius is the hypotenuse, which is 14. and the distance is the missing leg.

so 14^2=6^2+x^2

196=36+x^2

sqrt160=x

4sqrt10=x

Answer:

$180

Step-by-step explanation:

First, you have to calculate the amount that Olivia would have paid at the end of the loan which would be the result of multiplying her monthly payment for the number of payments:

Total payment= $308*(12*5)

Total payment= $308*60

Total payment= $18,480

Then, you have to calculate the amount that Garrett would have paid at the end of the loan:

Total payment= $311*(12*5)

Total payment= $311*60

Total payment= $18,660

Now, you have to calculate the difference in the amount Olivia and Garrett would have paid:

$18,660-$18,480= $180

According to this, an $18,000 loan will cost Garrett $180 more than Olivia.

Answer: A =350 (1.05)^t

Step-by-step explanation:

Hi, to answer this question we have to apply an exponential growth function:

A = P (1 + r) t  

Where:

p = original population

r = growing rate (decimal form; 5/100=0.05)

t= years

A = population after t years

Replacing with the values given:

A = 350 (1+0.05)^t

A =350 (1.05)^t

Answer:

r = 7/(9sinθ - cosθ)

to rectangular form is:

y = (1/9)x + 7/9

Step-by-step explanation:

Given that

r = 7/(9sinθ - cosθ)

Consider the following polar-to-rectangular equivalents.

x² + y² = r²

x/r = cosθ

y/r = sinθ

So

r = 7/(9sinθ - cosθ)

Can be written as

r = 7/(9y/r - x/r)

r = 7/(1/r)(9y - x)

Multiplying through by (1/r)

1 = 7/(9y - x)

Multiplying through by (9y - x)

9y - x = 7

9y = x + 7

Divide both sides by 9

y = x/9 + 7/9

y = (1/9)x + 7/9

And this is the answer

Answer:

y = (1/9)x + 7/9

Step-by-step explanation:

Divide both sides by 9

y = x/9 + 7/9

y = (1/9)x + 7/9

Divide both sides by 9

y = x/9 + 7/9

y = (1/9)x + 7/9

Answer: 364 with a remainder of 28

Step-by-step explanation:

14952/41

41 goes into 149 3 times

149 - (41 *3)

149 - 123 = 26

41 goes into 265 6 times

265 - (41*6)

265 - 246 = 19

41 goes into 192 4 times

192 - (41*4)

192 - 164 = 28

So 14952/41 = 364 with a remainder of 28

Answer:

40

Step-by-step explanation:

To solve this, we can create an equation that represents this situation. Since Christopher score 7 more than twice what Mathew scored, the equation will be:

C = 2M + 7

(Variables are representative of the first letter of each name)

Seeing as Christopher scored 87, we can put that into the equation and solve for M.

So, the equation will be:

87 = 2M + 7

Subtract 7 from both sides in order to isolate variable M on the right side.

80 = 2M

Now solve for M, which is 40 (divide both sides by 2).

50 = x

Step-by-step explanation:

The exterior angle of a triangle is equal to the sum of the opposite interior angles

105 = 55+x

Subtract 55 from each side

105-55 = 55-55+x

50 = x

Answer:

A

Step-by-step explanation:

The external angle of a triangle is equal to the sum of the 2 opposite interior angles.

105° is an exterior angle of the triangle , thus

x + 55 = 105° ( subtract 55 from both sides )

x = 50° → A

Answer:

4502 pieces of grass

Step-by-step explanation:

The radius of the semicircle is 36 meters, so its perimeter is:

Perimeter = pi * radius = 113.097 m

The perimeter of both semicircles is 2 * 113.097 = 226.194 m

So if the total perimeter is 395, the length of the rectangle is:

395 = 226.194 + 2*length

2*length = 168.8

length = 84.4 m

The width of the rectangle is 2 times the radius of the semicircle, so:

width = 2 * 36 = 72 m

Then the area of the rectangle is:

Area = length * width = 84.4 * 72 = 6076.8 m2

To find the number of grass pieces, we divide the rectangle area by the grass piece area:

number of pieces = 6076.8 / 1.35 = 4501.33 pieces

So we will need 4502 pieces to cover the rectangular area.

Answer:

4x +16 the slope is 4 because its parallel to the other equation

The solution is: the equation of the line that is parallel to the line

y - 1 = 4(x + 3) and passes through the point (4, 32) is y = 4x + 16.

A straight line is an endless one-dimensional figure that has no width. It is a combination of endless points joined both sides of a point and has no curve.

Here, we have,

When two lines are parallel, their slope stays the same. thus we have y = 4x (so far)

Then use the point (4, 32) to plug in the coordinates to y = 4x + b

y = 4x + b (because y-intercept changes)

32 = 4(4) + b

32 = 16 + b

b = 32 - 16

b = 16

now, we get,

the y-intercept is 16 and the equation of the line that passes through the point (4,32) and is parallel to the line y = 4x + 13 is y = 4x + 16.

Hence, The solution is: the equation of the line that is parallel to the line

y - 1 = 4(x + 3) and passes through the point (4, 32) is y = 4x + 16.

Answer:

OK but you get specific answers here and you can't always find the exact thing you're looking for on google

Step-by-step explanation:

Answer:

No, because they are parallel.

Kevin says that lines p and m will eventually intersect. The statement is incorrect because lines p and m are parallel.

Lines in a plane that are consistently spaced apart are known as parallel lines. Parallel lines don't cross each other. Perpendicular lines are those that cross at a straight angle of 90 degrees.

It is given that lines A and B intersect. Plane A contains lines p, m, and n. Line n is horizontal on the plane. Lines p and m are both going in the same direction and are identical. Plane B contains vertical line l which forms a right angle with line n.

In the image attached with the answer below it is observed that the two lines p and m are in the same plane and are parallel to each other.
