Pls Pls help me:
An observer on a clifftop 57m high observes a sailing boat at sea. The angle of depression to the shop is 15 degrees. Five minutes later the angle of depression was 25 degrees.
A) Is the boat sailing towards or away from the cliff?
B) Assuming the boat is sailing in a straight line, determine to the nearest meter how far the boat sailed between the two sightings?

Step-by-step explanation:

First you subtract five on both sides. Now we're left with C=6

Answer:

m∠Q = 121°

m∠R = 58°

m∠S = 123°

m∠T = 58°

Step-by-step explanation:

The sum of the interior angles of a quadrilateral = 360°

Create an expression for the sum of all the angles and equate it to 360, then solve for x:

      ∠Q + ∠T + ∠S + ∠R = 360

⇒ 2x + 5 + x + 2x + 7 + x = 360

⇒ 6x + 12 = 360

⇒ 6x = 360 - 12 = 348

⇒ x = 348 ÷ 6 = 58

So now we know that x = 58, we can calculate all the angles:

m∠Q = 2x + 5 = (2 x 58) + 5 = 121°

m∠R = x = 58°

m∠S = 2x + 7 = (2 x 58) + 7 = 123°

m∠T = x = 58°

Average cost per mile is $0.6

To calculate the average cost per mile that Kiara had to pay, we perform the following operations:

We add up all the payments Kiara made related to her car.

Later we divide the total value, in the number of miles traveled by Kiara

Answer: $112

Step-by-step explanation:

o get the solution, we are looking for, we need to point out what we know.

1. We assume, that the number 560 is 100% - because it's the output value of the task.

2. We assume, that x is the value we are looking for.

3. If 560 is 100%, so we can write it down as 560=100%.

4. We know, that x is 20% of the output value, so we can write it down as x=20%.

5. Now we have two simple equations:

1) 560=100%

2) x=20%

where left sides of both of them have the same units, and both right sides have the same units, so we can do something like that:

560/x=100%/20%

6. Now we just have to solve the simple equation, and we will get the solution we are looking for.

7. Solution for what is 20% of 560

560/x=100/20

(560/x)*x=(100/20)*x       - we multiply both sides of the equation by x

560=5*x       - we divide both sides of the equation by (5) to get x

560/5=x

112=x

x=112

now we have:

20% of 560=112

Step-by-step explanation:

Hi there!

We are given the following system:
x-2y=8

8x+6y=42

And we want to solve it by substitution

Substitution is where we solve one of the equations in the system for a variable for an expression containing the other variable, then substitute that expression into the other equation, then solve the equation for that variable, then use the value of the solved variable to find the value of the first variable.

It's easier to solve a system for a variable if the leading coefficient in front of a variable is 1, like with x in x-2y=8

So let's solve the equation for x.

add 2y to both sides

x-2y=8
 +2y +2y
________________
x=2y+8
Now substitute 2y+8 as x in 8x+6y=42

8(2y+8)+6y=42

Multiply

16y+64+6y=42

Subtract 64 from both sides

16y+6y=-22
Add 16y and 6y together

22y=-22

Divide both sides by 22

y=-1

Substitute -1 as y into x=2y+8 to solve for x

x=2(-1)+8

Multiply

x=-2+8

x=6

The answer is x=6, y=-1, or as a point, (6, -1)
Hope this helps!

We are asked to find, how much Carlos owns and how much they have together.

Explanation :-

At first, we just need to multiply 45 by 5, and then we will divide the value by 9, so we find that:

[tex]\qquad[/tex][tex] \bf \longrightarrow 45 \times 5 = 225[/tex]

[tex]\qquad[/tex][tex] \bf \longrightarrow \dfrac{225}{9} = 25[/tex]

Now to find out how much they have together. We have to add Paul's amount to Carlos' amount for that.

Answer:

18

Step-by-step explanation:

If the average of 6 numbers is 10, then the sum of those 6 numbers is:

6 x 10 = 60

To calculate the sum of the remaining 10 numbers, subtract 60 from the total sum of all the numbers:

240 - 60 = 180

Therefore, the average of the 10 remaining numbers:

180 ÷ 10 = 18

3221-2415=806

The restaurant has 806 ketchip packets left

Answer:

5,806

Because they got there 5,000 packets they subtracted 1,779 packets

5,000-1,779=3,221

Next remember they get 5,000 packets each week so then you add 5,000 to 3,221

3,221+5,000=8,221

next 2,415 packets were used so subtract 8,221 bu 2,415

8,221-2,415=5,806  so there's your answer
