Answer:

40\sqrt3\ m

Step-by-step explanation:

Given that,

The height of the tower, h = 40 m

The angle of elevation is 30°

We need to find the distance between the tower and the point. Let the distance is x. Using trigonometry,

\tan(30)=\dfrac{h}{x}\\\\\dfrac{1}{\sqrt3}=\dfrac{40}{x}\\\\x=40\sqrt3\ m

So, the distance between the tower and the point is equal to 40\sqrt3\ m.

5, 4 7/8, 4 9/10 in order least to greatest
Klio2033 [76]

The order from least to greatest is 4 7/ 8, 4 9/ 10 , 5

<h3>What are fractions?</h3>

Fractions are simply representatives of part of a whole.

The types of fraction are;

  • Mixed fractions
  • Simple fractions
  • Improper fractions
  • Proper fractions

From the information given, we have to arrange in order from least to greatest

5, 4 7/8, 4 9/10

Turn mixed fractions to improper fractions;

5, 39/ 8 , 49/ 10

From least to greatest is written thus;

39/ 8, 49/ 10 , 5

Thus, the order from least to greatest is 4 7/ 8, 4 9/ 10 , 5

Solve for x. MUST SHOW ALL WORK TO RECEIVE FULL CREDIT! (See picture for equation)
ioda
\frac{x}{2.4} = \frac{3}{8}

For proportions and to find x we have to cross multiply
8 × (x) = 3 × 2.4

8x = 7.2
Divide by 8 to isolate x

\frac{8x}{8} =  \frac{7.2}{8}
8 and 8 cancels out

x = 0.9

If you have a job that earns $120 in 2 days, how much would you earn in 6 days? Use a chart to show the proportion of earnings f
zepelin [54]
To figure this out, we need to use fractional proportions.

Currently, we have $120, the amount earned, and 2 days, the current rate.
Our fraction for this is: 120 / 2 = x / 6, x being the amount earned in 6 days.

Let's use a little technique to help us answer faster.

With our current money earned, 120, and our current days, 2, we can divide 120 by 2 to find out how many we earned in 1 day.

120 / 2 = 60.

We earned $60 per day.

With this formula, 60d, d being the amount of days, we can solve quicker.

We are solving for 6 days, so multiply $60 by 6 days.

60 x 6 = 360

Your proportion is : 

120/2 : 360/6

I hope this helps!
