I know this because you would divide 6 women by 3 to get two women so you would multiply the two days by 3 to get 6 days

Answer:

B = 212 feet

Step-by-step explanation:

Given that,

The angle of depression, [tex]\theta=27^{\circ}[/tex]

The height of the lighthouse, h = 108 feet

We need to find the horizontal distance from the boat to the base of the lighthouse. It can be calculated using trigonometry as follows :

[tex]\tan\theta=\dfrac{h}{B}[/tex]

Where

B is the horizontal distance

[tex]B=\dfrac{h}{\tan\theta}\\\\B=\dfrac{108}{\tan(27)}\\\\B=211.96\ ft[/tex]

or

B = 212 feet

So, the horizontal distance from the boat to the base of the lighthouse is 212 feet.

Answer:

x < -4

Step-by-step explanation:

2(-3x - 4) > 16

-6x - 8 > 16

-6x > 16 + 8

-6x > 24

-x > 4

x < -4

Answer:

x < -4

Step-by-step explanation:

2(-3x - 4) > 16

Distribute.

-6x - 8 > 16

Add 8 to both sides.

-6x > 24

Divide by -6. When dividing by a negative, flip the sign.

x < -4.

Answer:

x = 5

Step-by-step explanation:

The measure of an inscribed angle is 1/2 the measure of the intercepted arc.

∠X is an inscribed angle and arc QRS is its intercepted arc.

arc QRC has a measure of 122 + 76 = 198

Therefore, m∠X = 1/2(198) = 96

So, 19x + 1 = 96

19x = 95

x = 5

Answer:

[tex]a_{n}[/tex] = 20 - 9n

Step-by-step explanation:

There is a common difference d between consecutive terms, that is

d = 2 - 11 = - 7 - 2 = - 9

This indicates the sequence is arithmetic with nth term

[tex]a_{n}[/tex] = a₁ + (n - 1)d

where a₁ is the first term and d the common difference

Here a₁ = 11 and d = - 9 , then

[tex]a_{n}[/tex] = 11 - 9(n - 1) = 11 - 9n + 9 = 20 - 9n

Answer:

1587.6 m²

Step-by-step explanation:

[tex]A=\frac{1}{2} bh[/tex] where b is the base length and h is the height (b and h on the triangle will always be perpendicular to each other)

Plug in 75.6 m as b and 42 m as h

[tex]A=\frac{1}{2} (75.6)(42)\\A=\frac{1}{2}( 3175.2)\\A=1587.6[/tex]

Answer:

C. 80 square centimeters

Step-by-step explanation:

Edge 2021

The lateral surface area of the given square pyramid is 80 cm².

The lateral surface of an object is its entirety, excluding its base and top (when they exist).

Boundary - layer surface zone equals lateral surface area. This is to be contrasted from the total surface area, which includes the lateral surface area along with the base and top regions.

Given that, a square pyramid has side lengths each measuring 8 centimeters.

The height of the pyramid is 3 centimeters.

The lateral area of a square pyramid = 2al = 2a√[(a²/4) + h²]

= 2×8√[(8²/4) + 3²]

= 16√[(64/4) + 9]

= 16√[16 + 9]

= 16×5

= 80 cm²

Therefore, the lateral area of the pyramid is 80 cm².

Answer:

[tex]22\ km[/tex]

Step-by-step explanation:

One is given the following information:

One is asked to find the total distance covered on both of these days. In order to do so, one must remember in a fraction, any number over (1) is equal to the numerator (number over the fraction bar). Thus one can form the following equation:

[tex](Thursday)+(Friday) = Total\ distance[/tex]

Substitute,

[tex](Thursday)+(Friday) = Total\ distance[/tex]

[tex](10\frac{1}{1})+(10\frac{1}{1}) = Total\ distance[/tex]

Simplify,

[tex](10\frac{1}{1})+(10\frac{1}{1}) = Total\ distance[/tex]

[tex](10+1)+(10+1) = Total\ distance[/tex]

[tex](11)+(11)=Total\ distance[/tex]

[tex]11+11=Total\ distance[/tex]

[tex]22=Total\ distance[/tex]

The total distance around the track is 332.2 meters

The complete question is in the attached image

The given parameters are:

Radius, r = 25 m

Length, l = 87.6 m

Start by calculating the circumference of the two semi-circular ends using:

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

So, we have:

C = 2* 3.14 * 25

Evaluate

C = 157

The total distance around the track is then calculated as:

Total = 2l + C

This gives

Total = 2 * 87.6 + 157

Evaluate

Total = 332.2

Hence, the total distance around the track is 332.2 meters

Answer:

Implicit Form: 4x + y - 52 = 0

Step-by-step explanation:

8x + 2y = 104 => Move constant to the left and change the sign

8x + 2y - 104 = 0 => Divide both sides of the equation by 2

4x + y - 52 = 0

Step-by-step explanation:

Let's use the distributive property to simplify this problem.

The first thing we want to do is change the minus to plus a negative.

Now distribute or multiply the 2 by each of the terms inside the parentheses.

So we get 2(3y) + 2(-4) and this simplifies to 6y + -8

Note that if you wrote your answer as 6y - 8, it means the same thing.

Answer:

a = 4, b = - [tex]\frac{3}{2}[/tex]

Step-by-step explanation:

Given

[tex]\frac{8-3\sqrt{2} }{2}[/tex] = a + b[tex]\sqrt{2}[/tex] ( multiply both sides by 2 to clear the fraction )

8 - 3[tex]\sqrt{2}[/tex] = 2a + 2b[tex]\sqrt{2}[/tex]

For the 2 sides to be equal , then

2a = 8 ( divide both sides by 2 )

a = 4

and

2b = - 3 ( divide both sides by - 2 )

b = - [tex]\frac{3}{2}[/tex]
