Given thing are

cos Θ = 2/3

we know that Cos Θ = Adjacent Side / Hypotenuse, so we get

Adjacent Side = 2

Hypotenuse = 3

Hypotenuse : BC = 3

Adjacent Side : AB = 2 (Adjacent to ∠ Θ)

Opposite Side : AC = ? (Opposite to ∠ Θ)

To find the Opposite Side - AC , we use Pythagoras theorem ((Hypotenuse)2 = (Leg 1)² + (Leg 2)²)

AC = √ BC² - AB²

AC = √ 32 - 22

AC = √ 9 - 4

AC = √5

Now we will try to simplify square root of 5. As no pairs can be made the final value will be

__

AC = √ 5

So Sin, Cos and Tan will be as follows -

Sin Θ = Opposite Side / Hypotenuse

__

Sin Θ = √5/3

Tan Θ = Opposite Side / Adjacent Side

__

Tan Θ = √5/2

Cos Θ = Adjacent Side / Hypotenuse

Cos Θ = 2/3

Answer:

0.65

Step-by-step explanation:

Since we have given that

Cost of 8 pencils = 5.20

We need to find the cost of 1 pencil.

For this we'll use the unitary method,

The ordered pair of the parking lot is the coordinates of the lot in the coordinate plane

Parking lot B is located in the ordered pair (-3,4)

From the figure, we have the following highlights

Parking lot B is located at x = -3 on the horizontal axis, and it is located at y = 4 on the vertical axis.

So, we have:

(x,y) = (-3,4)

Hence, parking lot B is located in the ordered pair (-3,4)

Answer:

she earned $20 in tips

Step-by-step explanation:

- figure out how much she'll get payed in 12 hours of work, :

12 x $11.25 = $135 for 12 hours work, then find out 2/5 of $11.25 to find out how much she would get for the 2/5 of an hour she worked:

2/5 of $11.25 = $4.50, after all of that, add up both of these sums together to get her total pay for hours worked:

$135 + $4.50 = $139.50

now you need to subtract that sum from her total pay to find out how much money she earned in tips:

$159.50 - $139.50 = $20, so basically thats how i got 20.

Answer:

$8,580,000 (rounded) = $9,000,000

Step-by-step explanation:

Keep in mind, 2007 is four years after 2003.

So, 8(%) • 4 = 32(%)

Over the course of 4 years, the companies profits increased by a total of 32 percent.

(*Write 6.5m in standard form)

6,500,000 + 32% = $8,580,000

8,580,000 (rounded up) = 9,000,000

Answer:

50%

Step-by-step explanation:

The equation for circumference is:

[tex]C=2\pi r[/tex]

In this case, the radius and the circumference are directly proportional meaning that if the radius increases by 50%, the circumference will also increase by 50%.

Let's use some examples to prove this:

Radius : 2

Increase by 50% : 2*50%=2*(50/100)=2(1/2)=1 --> 1+2 = 3

[tex]C=2\pi r=2\pi 3=6\rightarrow 50 \ percent\ increase\ from\ 4\\C=2\pi r=2\pi 2=4[/tex]

Radius : 4

Increase by 50% : 4*50%=4*(50/100)=4(1/2)=2 --> 2+4 = 6

[tex]C=2\pi r=2\pi 6=12\pi\rightarrow50\ percent\ increase\ from\ 8\\C=2\pi r=2\pi 4=8\pi[/tex]

In both cases, when we increased the radius by 50%, the circumference also increased by 50%, proving our previous statement correct.

Therefore, when the radius of a circle is increased by 50%, the circumference will also increase by 50%

11p =8

11p=8

p=8/11

Answer:

p=0, p=1.5, p=-7

Step-by-step explanation:

Assuming we need the equation to equal zero we do this.

5p(2p-3)(p+7)

5p = 0        (2p-3) = 0       (p+7)= 0  Separate each part

5(0) = 0      2(1.5)-3 = 0.   (-7)+7 = 0  Replace P so the outcome is 0

Step: Solvex−9y=25for x:

x−9y=25

x−9y+9y=25+9y(Add 9y to both sides)

x=9y+25

49

(Divide both sides by 49)

y=−3

Step: Substitute−3foryinx=9y+25:

x=9y+25

x=(9)(−3)+25

x=−2(Simplify both sides of the equation)

Therefore answer:

x=−2 and y=−3 which is (-2, -3)

Answer:

Permeter= 68m

Area= 289m^2

Step-by-step explanation:

Perimeter = 17^4 = 68m cause perimeter is the total length and square has 4 sides

Area= 17 ^17= 289m^2

Area of square is to multiply length x length

The perimeter and area of the mat will be 68 meters and 289 square meters.

All the sides of a square are congruent. Let a be the side length of the square. Then the area of the square is the square of the side length of the square.

The area of the square will be

A = a² square units

The sum of all the sides of the square will be known as the perimeter of the square.

The perimeter of the square will be

P = 4a units

A sporting goods store sells square exercise mats that are 17 m on a side.

The area of the square will be

A = 17²

A = 289 square meters

The perimeter of the square will be

P = 4 x 17

P = 68 meters

The perimeter and area of the mat will be 68 meters and 289 square meters.

The price of the given menu items can be used to find the price of Egg &

Mash to be £2.1.

Response:

The price for Egg & Mash is £2.1

Let x represent the cost of Egg, let y represent the cost of Chips, let

z, represent the cost of Sausages, and a the cost of Mash we have the

following system of linear equations;

x + y = 3...(1)

z + y = 3.6...(2)

z + a = 2.7...(3)

x + a = Required

Solution:

Subtracting equation (1) from (2) gives;

z + y - (x + y) = 3.6 - 3 = 0.6

z - x = 0.6

Therefore;

z is £0.6 more expensive than x

x = z - 0.6

By plugging in the value of x = z - 0.6, gives;

x + a = z - 0.6 + a = z + a - 0.6

z + a = 2.7, which gives;

x + a = z + a - 0.6 = 2.7 - 0.6 = 2.1
