Natasha2012 [34]

Answer:

13.5 mg

Step-by-step explanation:

Here given Cobalt isotope has half life of 5.3 years.

Initial amount is 50 mg.

Given time(10 years) is roughly equals to two half life.

So, after 5.3 year 25 mg of isotope will left further in next half life only around 12.5 mg remains.

Among options 13.5 mg is the best possible

The table gives an inequality and a number to multiply both sides of the inequality by. Identify the new, true inequality.

zepelin [54]

Multiplying both sides of an inequality by a negative number reverses the inequality symbol.

<h3>How to determine the true inequalities?</h3>

The table of values is given as:

A: (-16 > -4) (-16 < -4) (-16 = -4)

B: (40 > 8) (40 < 8) (40 = 8

C: (-45 > 15) (-45 < 15) (-45 =15)

D: (35 > -20) (35 < -20) (35 = -20)

In the above list of inequalities, the true inequalities are

-16 < -4 --- because -16 is less than -4

40 > 8 --- because 40 is greater than 8

-45 < 15 --- because -45 is less than 15

35 > -20 --- because 35 is greater than -20

Lastly, when an inequality is multiplied or divided by a negative number, the inequality sign changes

The sun is directly overhead. The shadow of the balloon falls

Mariana [72]

The height of the ballon is 34 feet 2 inches.

To be able to solve this question, we need to understand the concept of angle of elevation.

<h3>What is the angle of elevation?</h3>

An angle of elevation is the angle formed between the horizontal plane (adjacent line) to the line of sight(elevation) from the viewer's eye to the object located in the space.

The diagrammatic expression for the question given can be seen in the image attached below.

From the image below, we can determine the height of the ballon by taking the tangential trigonometric function.

$\mathbf{tan \theta = \dfrac{opposite}{adjacent}}$

$\mathbf{tan \ 67= \dfrac{x}{14 ft \ 3 in }}$

Let's first convert 14 ft 6 in to ft, by doing so, we get 14.5 ft

$\mathbf{tan \ 67= \dfrac{x}{14.5\ ft }}$

x = tan 67 (14.5 ft)

x = 2.356(14.5 ft)

x =34.162 ft

To ft and inches, we have:

x = 34 ft 2 inches

Alchen [17]

The sum will be:

sigma(i = 1 to infinity, 30*(2/5)^i)

-> $\lim_{i \to \infty} \frac{30(1- \frac{2}{5}^{i} )}{ \frac{3}{5} }$

Which is equal to 30/(3/5) = 50
