Answer:

L = 34 - 0.5d

21 feet

Step-by-step explanation:

The initial water level ; 34

the amount is rises per day; 0.5

"L" is the water level,

"d" is the days passed.

In order to find the water level, one will have to multiply the amount the water rises each day, by the days passed. Then one will have to subtract that from the initial water level, hence the equation formed is the following;

L = 34 - 0.5d

Substitute in 26 for "d", to solve for the water level after 26 days.

L = 34 - 0.5(26)

L = 34 - 13

L = 21

What is the purpose of knowing the angle of elevation and depression in relation to the field of surveyor, military/police, aero

Alex73 [517]

The purpose of knowing the angle of elevation and depression in relation to the field of surveyor, military/police, aeronautics (pilot), engineers, landscapers, and architects is discussed below

<h3>What is angle of elevation and depression?</h3>

If a person stands and looks up at an object, the angle of elevation is the angle between the horizontal line of sight and the object. If a person stands and looks down at an object, the angle of depression is the angle between the horizontal line of sight and the object.

If the pilot looks straight out, that line of sight is horizontal (focused on the distant horizon). The pilot might see the airport's runway, distant buildings, or even mountains in her field of view.

If the pilot looks down at the ground, the one will see the ground crew. The angle of depression is the angle that is formed between the horizontal and the downward looking angle. It is always a downward view, an angle below the horizon.

For the ground crewmember, looking down would not be much help in communicating with the pilot in her cockpit seat. The crewmember will look up, above the horizontal line, to see the pilot. The ground crewmember's angle of vision if an angle of elevation, the angle above the horizon.

Angle of elevation or depression in a survey can be defined as the angle subtended between the line of sight passing through the scope and the horizontal axis of the instrument.

Engineers, landscapers, architects all use trigonometry in their everyday life to help them efficiently and safely create or design something new.

When making a batch of orange juice for her basketball team Jackie used 5 times as much water as concentrate. There were 32 more

AnnZ [28]

Answer:

48 cups of orange juice, 24 containers.

Step-by-step explanation:

Given:

Jackie used 5 times as much water as concentrate to make orange juice.

There were 32 more cups of water than concentrate.

Question asked:

How much juice did she make in all ?

She poured the juice in 2 quart containers how many containers could she fill ?

Solution:

Let concentrate used in the juice = $x$

<u>As Jackie used 5 times as much water as concentrate:</u>

Then water used in the juice = $5x$

<u>According to question:</u>

<u>To make orange juice 32 more cups of water used than concentrate is equals to to make orange juice</u>, Jackie used 5 times as much water as concentrate, we will write this as:-

$x+5x=x+x+32\\6x=2x+32\\$

Subtracting both sides by $2x$

$4x=32\\$

Dividing both sides by 4

$x=8$

Concentrate used in the juice = $x$ = 8 cups

Water used in the juice = $5x$ = $5\times8=40\ cups$

Total quantity of juice =8 + 40 = 48 cups

Thus, she made 48 cups of orange juice for her basketball team.

Now, as she poured the juice in 2 quart containers, we have to find number of containers could be filled, we will simply divide total quantity of juice by 2 quart

Number of 2 quart containers = 48 cups $\div$ 2 = 24 containers

Thus, she can fill 24 containers.

What two numbers adds up 2 and multiplies -80

viva [34]

-8 and 10.

The 8 has to be negative because otherwise the 2 would end up being negative, not positive.

Simplify by dividing [ -3/-8] divided by 5/9 (5 points)

rewona [7]

Answer: D

Step-by-step explanation:

(3/8) / (5/9) is the same as multiplying (3/8) by (9/5) which is 27/40. I'm not sure if there's an error between C and D because those are both the same answer since dividing a negative number by a negative number gives you a positive number.

I think C was supposed to be -27/40 so D is the correct answer since it's positive.

Which number line represents the solution set for the inequality-1/2x>_4

Vesna [10]

Answer:

Step-by-step explanation:

Firstly, we solve for x

-x ≥ 2 * 4

-x ≥ 8

Multiply both sides by -1

x ≤ -8

So we look at the inequality represented by this;

We can see that the correct inequality is option B;
