Jesse drives to work. The distance Jesse’s car travels (d) on a number of gallons of gas (g) is given by the equation d = 15g. The constant of proportionality in terms of distance traveled per gallon of gas is

a. 15
b. 5
c. 1
d. 1/15

Answers

Answer 1

Answer:

Answer: Option 'd' is correct.

Step-by-step explanation:

Since we have given that

Distance traveled by Jesse's car = d

Number of gallons used = g

The relation between distance and number of gallons used is given by

$d=15g$

We need to find the constant of proportionality in terms of distance traveled per gallon of gas.

So, Constant of proportionality = $(Distance\ traveled)/(Gallon\ of\ gas)=(d)/(g)$

Since we have

$d=15g\n\n(d)/(g)=(1)/(15)=Constant\ of\ proportionality$

Hence, Option 'd' is correct.

You have 2 triangles and 3 rectangles.
Start with a triangle:
area is base side * height / 2 -> 4 * 3 / 2 = 6
The other triangle has the same area: 6

First rectangle: side * other side -> 7 * 5 = 35
Second rectangle: 7 * 4 = 28
Third rectangle: 7 * 3 = 21

Now simply add all this together: 6+6+35+28+21 = 96

For which value of O is sin O= -1

Answers

Answer:

O = 2 π n - π/2 for n element Z

Step-by-step explanation:

Solve for O:

sin(O) = -1

Hint: | Eliminate the sine from the left hand side.

Take the inverse sine of both sides:

Answer: O = 2 π n - π/2 for n element Z

assuming you meant sin(θ) = -1, Check the picture below.
