P, Q and R are points in the same

Anna11 [10]

Answer: 119°

Step-by-step explanation:

From the positive y-axis, all angles are measured clockwise

PR = PQ + QR = 5[150°] + 3[60°]

X = 5*sin150 + 3*sin60 = <u>5.1</u>

Y = 5*Cos150 + 3*Cos60 = <u>-2.83</u>

TanA = X/Y

A = -61° = 61° East of South = 119° Clockwise

Therefore, the bearing of R from P is 119°

What is the slope for this question?

ivolga24 [154]

Answer:

$-1$

Step-by-step explanation:

This is a really nice line that goes through a lot of grid points (where the lines intersect).

One easy way to find the slope is the phrase "rise over run." "Rise" is the name for vertical motion from point-to-point. "Run" is the name for horizontal motion from point-to-point.

Pick two easy points on the line, say (0, 0) and (1, -1).

If you go from (0, 0) to (1, -1), the rise is -1 -- because you went DOWN 1 unit.

The run is 1 -- because you went RIGHT 1 unit.

$\frac{\text{rise}}{\text{run}} =\frac{-1}{1} =-1$

The slope is -1.

Cool fact: You'll get the same value if you use any two points on the line.

Solve using substitution. <br> M = 5p + 8 <br> M = -10p + 3

bezimeni [28]

The answer is -1/3.
What you can do is substitute the botton "M" with 5p+8
so it would turn out to be 5p + 8= -10p + 3. You then add 10p to each side resulting in 15p + 8 = + 3. You then minus the 8 resulting in 15p= -5. So you then divide -5 by 15 resulting in p=-1/3

You are part of the research group that hypothesized that relative humidity played a role in the transpiration differences. What

aleksandrvk [35]

Answer:

<h2>A) Population A has a high water potential and loss due to transpiration because of the increased humidity.</h2>

Step-by-step explanation:

Notice that the hypothesis is that relative humidity affects the transpiration of the body. So, in order to prove such hypothesis, we need to find enough evidence about water loss due to higher humidity. Knowing the relative humidity as the relation between water vapor and the pressure of it.

Therefore, the right answer is A, because we need to prove that a high water potential and loss due to transpitation happens because of the increased humidity.

Twice last month, Judy Carter rented a car from a car rental company and traveled around the Southwest on business. The company

tatiyna

Answer:

$31 and $0.16

Step-by-step explanation:

Let the rental company rents its car for a $x daily fee and a $y as the mileage charge.

So, on his first trip Judy drove 450 miles for 4 days and the rental cost was $196.

So, 4x + 450y = 196 ......... (1)

⇒ 12x + 1350y = 588 ......... (a)

On his second trip Judy drove 200 miles for 3 days and the rental cost was $125.

Hence, 3x + 200y = 125 ......... (2)

⇒ 12x + 800y = 500 .......... (b)

Now, solving equations (a) and (b) we get,

550y = 88

⇒ y = $0.16

Now, from equation (2) we get 3x = 125 - 200y = 93

⇒ x = $31

So, the daily fee is $31 and the mileage charge is $0.16. (Answer)
