Point O is between points G and D on line m. Which of the following statements is not necessarily true?a. O, G and D are collinear.
b. O, G and D are coplanar.
c. GO + OD = GD
d. GO = OD

Answers

Answer 1

Answer:

Answer: d. GO = OD

Step-by-step explanation:

Given: Point O is between points G and D on line m.

It means that they are on same line m.

We know that collinear points are the points lie in the same line.

Hence O, G and D are collinear.

Also, coplanar points are the points lie in the same plane.

Since if three points are collinear, then they are coplanar.

Therefore, O, G and D are coplanar.

The statement which is not necessarily true is d. GO = OD because it is not given that o lies exactly middle to points G and D.

Answer 2

Answer: c. GO + OD = GD

hope this helps

The loudness, L , of a sound (measured in decibels, dB) is inversely proportional to the square of the distance, d , from the source of the sound. A person 14 feet from a jetski, it is 75 decibels loud.

How loud is the jetski when the person is 45 feet away?

Answers

Answer

7.2593 decibels

Explanation

L ∝ 1/d² Inserting the constant of variation,

L = k/d²

k = Ld²

= 75 × 14²

= 14,700

When d = 45 feet;

L = 14,700/45²

= 14,700/2,025

= 7.2593 decibels

When the person is 45 feet away from the jetski, it is approximately 24.07 decibels loud.

How to determine How loud is the jetski when the person is 45 feet away

We can use the inverse square law to find how loud the jetski is when the person is 45 feet away. The inverse square law states that the loudness ($L$) is inversely proportional to the square of the distance ($d$):

$L = k \cdot (1)/(d^2)$

We are given that when the person is 14 feet away, $L = 75$ . We can use this information to find the value of $k$:

$75 = k \cdot (1)/(14^2)$

Now, solve for $k$:

$k = 75 \cdot 14^2$

Now that we have the value of $k$, we can use it to find the loudness ($L$) when the person is 45 feet away:

$L = k \cdot (1)/(45^2)$

Plug in the value of $k$ we found:

$L = 75 \cdot 14^2 \cdot (1)/(45^2)$

Calculate this expression to find the loudness ($L$) when the person is 45 feet away:

$L \approx 24.07 \text{ dB}$

So, when the person is 45 feet away from the jetski, it is approximately 24.07 decibels loud.

A business has $15,000 to spend on airline tickets to travel to a conference. It wants 27 of its employees to attend. The business wants to buy as many business-class seats as possible. The business-class seats cost $700. The economy-class seats cost $375. How many of each type of ticket should the business purchase?11 business class and 16 economy class

12 business class and 15 economy class

15 business class and 12 economy class

16 business class and 11 economy class

Answers

In order to get as many tickets they need 15 business class tickets and 12 economy class tickets (700x15=10,500)(375x12=4500) Which when you add those two makes 15,000.
