Answer:

Step-by-step explanation:

E is incorrect if you want the point to be exactly on the line. (8,158) is on the line.

D is true. But it would reduce down to the constant of 19.75.

C is true. The word about implies you are working with an estimate.

B is true. That's almost the definition of a proportionality definition.

A is not true. The denominator has to be one. so it would be so many gallons in 1 minute.

Q/R=8/d Solve for d please and thank you!

tensa zangetsu [6.8K]

The value of d in equation Q/R=8/d is 8R/Q.

Given an equation Q/R=8/d.

We are required to find the value of d in the given equation.

Equation is basically the relationship between two or more variables that are expressed in equal to form. The values that we enter is known as domain and the values that we get is known as range. It can be linear equation, quadratic equation, cubic equation.

The equation is :Q/R=8/d

We have to take d in right side of equal to sign and Q,R to the left side of right side of equal to sign.

d=8R/Q

Hence the value of d in equation Q/R=8/d is 8R/Q.

The wind is blowing N 35.0 degrees W at 1.60 * 10^2 mph. A plane has an engine speed of 3.20 * 10^2 mph. Where should the pilot

Answer: 24.2° SouthWest

Step-by-step explanation:

First step: DRAW A PICTURE of the vectors from head to tail (see image)

I created a perpendicular from the resultant vector to the vertex of the given vectors so I could use Pythagorean Theorem to find the length of the perpendicular. Then I used that value to find the angle of the plane.

Perpendicular (x):

cos 35° = adjacent/hypotenuse

cos 35° = x/160

→ x = 160 cos 35°

Angle (θ):

sin θ = opposite/hypotenuse

sin θ = x/320

sin θ = 160 cos 35°/320

θ = arcsin (160 cos 35°/320)

θ = 24.2°

Direction is down (south) and left (west)
