Answer the volume based Question. I will make uh brainliest + 50 points​

Reading the given Question , we get to know that 180 ft. is the height of lighthouse and 27° is the angle of depression from top of it to a ship in the ocean

(Figure is attached )

For finding base length from the ship to base of lighthouse ,

Tanθ = perpendicular/base

Tan 27° = 180ft/base

Base = 180/0.5095 (Value of tan 27° is 0.5095)

Base = 353.28 ft.

Base = 4239.36 inches

Answer:

10 Inches

Hope it helps, have a fantastic day.

Step-by-step explanation:

The Circumference of a circle can be displayed by this formula:

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

[tex]C[/tex] is the circumference, and [tex]r[/tex] is the radius.

So just plug in 31 for [tex]C[/tex], and simplify:

[tex]31 = 2\pi r[/tex]

Because the question is asking for the diameter, we only need to divide both sides by pi, as [tex]2r[/tex] is the same thing as diameter.

[tex]9.87 = 2r[/tex] (rounded to the nearest hundredth)

We can even rewrite [tex]2r[/tex] as [tex]d[/tex], which stands for diameter, to make things a little simpler.

[tex]9.87 = d[/tex]

Now we just take 9.87, and round it to the nearest whole number, and we get 10. So your answer is 10 Inches.

Hope it helps, have a fantastic day.

Answer: (x +7)^2 +(y +6)^2 = 9

Step-by-step explanation:

The given circle appears to be centered at (-7, -6) and have a radius of 3. The standard form equation of a circle is ...

 (x -h)^2 +(y -k)^2 = r^2 . . . . . . circle of radius r centered at (h, k)

For (h, k) = (-7, -6) and r=3, your circle is ...

 (x -(-7))^2 +(y -(-6))^3 = 3^2

 (x +7)^2 +(y +6)^2 = 9

The relation that helps you write an equation for x is, "the sum of angles in a triangle is 180°."

__

  (4x -4)° +x° +(6x -3)° = 180° . . . . . sum of angles in this triangle

  11x -7 = 180 . . . . . . . divide by °, collect terms

  11x = 187 . . . . . . . . add 7

  x = 17 . . . . . . . . . divide by 11

  m∠J = (6x -3)° = (6(17) -3)° = 99°

  m∠L = x° = 17°

Answer:

Step-by-step explanation:

x² + 10x + 21 = x² + (3x + 7x) + 21

                    = (x² + 3x) + (7x + 21)

                    = x(x + 3) + 7(x + 3)

                    = (x + 3)(x + 7)  

Answer:

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

Step-by-step explanation:

Looking at the graph we see our zeros which is on the x-axis is -1 , 2, 3.

Thus create an equation.

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

The linear systems of inequalities model this situation will be 2x + 3y ≥ 30 and 6x + 4y ≤ 120. Then the correct option is A.

A linear system is one in which the parameter in the equation has a degree of one. It might have one, two, or even more variables.

A woodworking artist makes two types of carvings: type X and type Y.

He spends 2 hours making each type X carving and 3 hours making each type Y carving, and he can spend up to 30 hours each week making carvings.

His materials cost him $6 for each type X carving and $4 for each type Y carving, and he must keep his weekly cost for materials to $120 or less.

If x is the number of type X carvings he makes in a week and y is the number of type Y carvings he makes in a week.

Then the linear systems of inequalities models this situation will be

2x + 3y ≥ 30 and 6x + 4y ≤ 120

Thus, the correct option is A.

Answer:

4.5 mph or 9/2 mph

Step-by-step explanation:

Let x be the rate of the current

Formula: Distance = rate x time

where rate upstream =(12-x) and time =2 hours

15=(12-x)(2)

15=24–2x

2x=24–15

2x= 9

x=9/2=4.5 miles per hour (rate of current)

THE ANSWER: (5, -6)

Please read the explanation... it always helps... trust me...

Step-by-step explanation:

Okkeeeee lets beginnnn....

A translation is when you move a point of shape in a coordinate plane

so a translation of a point to the right means you are moving the point to the right of the coordinate plane meaning the positive side of the x-axis... so in this case you will need to add 4 to the x-coordinate....

simarily to the "down four units"

moving it down means subtraction.... meaning you need to subtract 4 from -2 which gets you -6...

A mean is an arithmetic average of a set of observations. The height of the 9th-grade students will be 66.7±4 inches.

A mean is an arithmetic average of a set of observations. it is given by the formula,

Mean = (Sum of observations)/Number of observations

Given the height of the 10 selected students is {66, 61, 67, 61, 75, 71, 70, 61, 61, and 74}, also, the standard deviation of the 9th-grade students is 4 inches. Therefore, The mean height in inches of the selected students is,

Mean = (66+61+67+61+75+71+70+61+64)/10 = 66.7inches

Therefore, the height of the 9th-grade students will be 66.7±4 inches.

Answer:

The number of walnut pounds we need to add is 10

Step-by-step explanation:

We need to make a mixture that costs $1 per pound.

That means that the total cost of our mixture, divided by the number of pounds must be equal to 1.

[tex]\frac{MixtureCost}{NumberOfPounds} = 1[/tex]

Well, we know that the total cost of our mixture is equal to the cost of the cashews + cost of walnuts.

[tex]MixtureCost = CashewsCost + WalnutsCost[/tex]

We also know that we'll buy 8 pounds of cashews that cost $1.25 each and some amount of pounds (which we'll call x) of walnuts that cost $0.80.

Knowing all of that, we can write this:

[tex]MixtureCost=8*1.25 + x*0.8[/tex]

If we make that multiplication, we have that

[tex]MixtureCost=10+x*0.8[/tex]

Now that we know the cost of our mixture, we just need to know the total number of pounds... But we already know that, don't we?

We know that there are 8 pounds of cashews and x pounds of walnuts, so here's what we can write:

[tex]NumberOfPounds=8+x[/tex]

Now, if we plug in the values we found in the first equation, here's what we have:

[tex]\frac{10+x*0.8}{8+x}=1[/tex]

The 8+x is dividing, so i'll pass it to the other side multiplying:

       [tex]10+0.8*x=x+8[/tex]

The 10 in the left side will go to the right side with a negative sign:

[tex]0.8x=x-2[/tex]

Now, if I pass the x from the right side to the left one changing signs:

[tex]0.8x-x=-2\\\\-0.2x=-2[/tex]

By changing signs from both sides, we have that:

[tex]0.2x = 2\\\\x = 10[/tex]

Therefore, the number of walnut pounds we need to add is 10

Answer:

5 days

Step-by-step explanation:

This problem is an inverse proportion case. Having two variables: number of workers and time (in days); when we increase the number of workers, the time needed decreases; vice versa. Therefore, we can use the multiplication method: (workers * time) will always stay constant.

Let's say the time (in days) needed by the eleven workers is t,

5*20 = (3*10) + (14*t)

100 = 30+14t

70 = 14t

5 = t

It will take the eleven-workers 5 more days to finish the road.

Answer:

C. is the correct answer

Step-by-step explanation:

A. is incorrect because the sequence does not start with 15

B. is incorrect because the pattern increases by 5, not multiplied by 5

C. is correct because all of the even numbers in the pattern do end in 0

D. is incorrect because even numbers don't end in 5's

Hope this helps!

Answer: "Every even-numbered term in the pattern has a 0 in the evens place"

Step-by-step explanation:

     We can compare each statement to the pattern and see which ones don't apply.

   The first one is not true. We are adding 5, not having a sum of previous numbers.

  The second one is not true, it is adding 5. Not 5 times greater.

  An even number is a number ending in 0, 2, 4, 6, or 8. This means

that the third option is correct, giving us our answer.
