Answer:

As per the statement

The altitude of the balloon is 50 feet and the rope is 75 feet long.

⇒ Altitude of the balloon = 50 feet.

And length of the rope = 75 feet.

We have to find the angle that rope makes with ground,

Using Sine ratio:

\sin \theta = \frac{\text{Opposite side}}{\text{Hypotenuse side}}

You can see the diagram as shown below.

Here,

Opposite side =  Altitude of the balloon = 50 feet.

Hypotenuse side =  length of the rope = 75 feet.

Substitute the given values we have;

\sin \theta = \frac{50}{75} =\frac{2}{3}

⇒\theta = \sin^{-1} (\frac{2}{3}) = 41.8°

Therefore, the angle that the rope makes with the ground is, 41.8 degree

Answer:

The angle that the rope makes with the ground is 41.8°.

Step-by-step explanation:

Given : The altitude of the balloon is 50 feet and the rope is 75 feet long.

To find : What is the angle that the rope makes with the ground?

Solution :

First we refer the image attached below.

Altitude of the balloon is the opposite side AB= 50 feet

Length of the rope is the hypotenuse side AC= 75 feet

Using the trigonometric ratios,

\sin \theta = \frac{\text{Opposite side}}{\text{Hypotenuse side}}

Substitute the values,

\sin \theta = \frac{50}{75}

\sin \theta =\frac{2}{3}

\theta = \sin^{-1} (\frac{2}{3})

\theta =41.8^\circ

Therefore, the angle that the rope makes with the ground is 41.8°.

Answer:

See below in bold.

Step-by-step explanation:

1.  x/8 = 15/24

Cross multiplying:

24x = 8*15

x = (8*15)/24

x = 5.

2.   5/6 = 35/x

5x = 6*35

5x = 210

x = 210/5

x = 42.

3.<em>  </em>18/42

Divide top and bottom by 6:

18 / 6 / 42/6

= 3/7.

4.  15/75

Divide top and bottom by 15:

= 1/5.

Answer:

15 = 0.025

16= 3 years

Step-by-step explanation:

15.

I=prt

15= (200)(r)(3)

200(3) = 600r

15 divided by 600r = 40 (0.025)

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

16.

I=prt

t= \frac{I}{Ixp} \\t= \frac{90}{0.05x600} \\t= 3

t= 3 years

If Mike has m pencils and Jen has three times as many pencils as Mike, how many more pencils does Jen have?
tiny-mole [99]

Answer:

If Sarah has three times as many pencils as Mike she has 3  times the number of pencils Mike has which is equivalent to 3 * m. That means Mike has m pencils and Sarah has 3m pencils. they have m + 3m pencils. The expression would be total:  m + 3m.

Write an equation of the line that is perpendicular to 3x - 4y equals 9 + contains (-4, -5)
Inga [223]
  • Slope-Intercept Form: y = mx+b, with m = slope and b = y-intercept

So perpendicular lines have <u>slopes that are negative reciprocals</u> to each other, but firstly we need to find the slope of the original equation. The easiest method to find it is to convert this standard form into slope-intercept.

Firstly, subtract 3x on both sides of the equation: -4y=-3x+9

Next, divide both sides by -4 and your slope-intercept form of the original equation is y=\frac{3}{4}x-\frac{9}{4}

Now looking at this equation, we see that the slope is 3/4. Now since our new line is perpendicular, this means that <em>its slope is -4/3.</em>

Now that we have the slope, plug that into the m variable and plug in (-4,-5) into the x and y coordinates to solve for the b variable as such:

-5=-\frac{4}{3}*-4+b\\\\-5=5\frac{1}{3}+b\\\\-10\frac{1}{3}=b

<u>In short, your new equation is y = -4/3x - 10 1/3.</u>
