Answer:

Bc = √63 ft

Step-by-step explanation:

Here, we want to get the length of BC

As we can see, there is a right angled triangle ABC, with 12ft being the hypotenuse and 9 ft the other side

So we want to get the third leg which is BC

we can use the Pythagoras’ theorem here

And that states that the square of the hypotenuse equals the sum of the squares of the two other sides

let the missing length be x

12^2 = x^2 + 9^2

144 = x^2 + 81

x^2 = 144-81

x^2 = 63

x = √63 ft

Answer:

16.8 cubic metres

Step-by-step explanation:

Given: 1 cubic foot = 6.23 gallons

           1 cubic foot = 0.028 cubic metres

Let the conversion into cubic metres be represented by x.

Thus we can say that;

6.23 gallons = 0.028 cubic metres

and

3738 gallons = x cubic metres

So that,

x = [tex]\frac{3738*0.028}{6.23}[/tex]

   = 16.8

x = 16.8 cubic metres

The conversion of 3738 gallons into cubic metres is 16.8 cubic metres.

Answer:

[tex]sin 54 = \frac{x}{14}[/tex]

Step-by-step explanation:

[tex]sine = \frac{opposite}{hypotenuse}[/tex]

Side z is the adjacent, since it is next to the angle you are solving for.

Side x is the opposite, since it is opposite the angle you are solving for.

The side measuring 14 is the hypotenuse, since it is across from the right angle.

[tex]sin 54 = \frac{x}{14}[/tex]

Work Shown:

To find the scale factor, we divide a side of triangle MNO over a corresponding side of triangle FGH. We can only pick the horizontal bottom sides since we don't know what x is yet.

scale factor = ON/HG = 15/9 = (5*3)/(3*3) = 5/3

In decimal form, this is approximately 5/3 = 1.67; however, I find it's better to stick with the fraction since it's exact.

---------------

Let's solve for x

One way to do so is to follow these steps

(FG)/(MN) = (HG)/(ON)

6/x = 9/15

6*15 = x*9 ..... cross multiply

90 = 9x

9x = 90

x = 90/9

x = 10

Or we could solve like this

(FG)/(HG) = (MN)/(ON)

6/9 = x/15

6*15 = 9x

90 = 9x

9x = 90

x = 90/9

x = 10

We end up with the same result because we got to 90 = 9x after cross multiplying, which was found in the previous set of steps as well. There are other ways to solve using a proportion. But they should all lead to x = 10.

Note how,

MN/FG = 10/6 = (5*2)/(3*2) = 5/3

which was the scale factor we found earlier

5/3 is going to be your answer.

The length of the side of the cube, rounded to 1 decimal place, is approximately 7.6 cm .

To find the length of the side of a cube given its volume, we need to find the cube root of the volume .

Given that the volume of the cube is 413 cm³, we can calculate the length of its side as follows:

side length = ∛( volume )

side length = ∛( 413 cm³)

side length ≈ 7.6 cm (rounded to 1 decimal place)

Therefore, the length of the side of the cube, rounded to 1 decimal place, is approximately 7.6 cm .

Answer:

Angle 3 is 95, angle 1 is 30.

Step-by-step explanation:

I already answered a lot of your other angle questions so I will make this one QUICK...

Angle 4 is 85, so to find angle 3, simply subtract: 180 - 85 = 95

So angle 3 is 95

We know two out of the three angles in a triangle and they are: 95 and 55, so 95 + 55 = 150. The sum of the angles in a triangle is 180 so we have: 180-150 = 30, which is the answer for angle 1.

So angle 1 is 30

After solving the equations, the distance between two airplanes after two hours will be equal to 861.21 miles.

The speed of an entity, which is a scalar quantity in regular usage and kinematics, can be defined as the size of the change in direction per unit of time or the size of the change in position over time for an object. The initial speed is the upper limit of maximum pace as the duration of a time interval gets closer to zero.

Assume that both the planes are on similar point A at the start.

Assume that x is the 325 mph flying object.

Consequently, it would have traveled a distance of after two hours of 325 × 2 = 650 miles.

Let B represent the location of the plane two hours later.

That means AB = 650 miles

Assume that y is the 300 mph flying object.

It would have traveled a distance of two hours = 300×2=600 miles.

After two hours, let C represent the location of the second plane.

This means AC=600 miles

After two hours, BC separates the two aircraft.

So, the angle between their paths is 87°.

Cos A = (AC² + AB² - AC²)/(2(AC)(AB))

cos 87 = (600² - 650² - AC²)/(2 × 600 × 500)

40822.04 = 782500 - AC²

AC² = 782500 - 4082204

AC = 861.21 miles.
