A signalized intersection has a cycle length of 60 seconds and an effective red time of 25 seconds. The effective green time is

alexandr402 [8]

Answer:

effective green time = 35 seconds

Step-by-step explanation:

given data

cycle length = 60 seconds

effective red time = 25 seconds

solution

we get here effective green time that is express as

effective green time = cycle length - effective red time ...........................1

put here value and we will get

effective green time = 60 seconds - 25 seconds

effective green time = 35 seconds

<h3>Answer:</h3>

A. y = (-6/5)x +10

<h3>Step-by-step explanation:</h3>

The given line has a negative slope (downward to the right). The only equation offered with a negative slope is the one of selection A.

_____

<em>Complete working</em>

A parallel line will have the same slope. If there are less-obvious choices to select from, you need to know the slope of the given line. That is computed from ...

... slope = (change in y)/(change in x)

The coordinates of two points are given, so we can find the slope as ...

... slope = (-4-2)/(-1-(-6)) = -6/5

There are a number of ways to write the equation of a line, but in slope-intercept form, the slope is the coefficient of x. You will be looking for a choice that has an x-coefficient of -6/5.

1: Triple the quantity of a number “n” plus 4 equals 27. what would the expression look like?

Diano4ka-milaya [45]

1: Triple the quantity of a number “n” plus 4 equals 27. what would the expression look like?

[ Triple the quantity of a number “n” ] 3n

[ plus 4 ] + 4

[ equals 27 ] = 27

[ all together ] <u>3n + 4 = 27</u>

<u />

<u>Solving:</u>

[ given ] 3n + 4 = 27

[ subtract 4 from both sides ] 3n = 23

[ divide both sides by 3 ] n = 7 $\frac{2}{3}$

2:Seventeen equals seven less than three times a number “n” what would the expression look like?

[ Seventeen equals ] 17 =

[ seven less than ] - 7

[ three times a number “n” ] 3n

[ all together ] <u>17 = 3n - 7</u>

<u />

<u>Solving:</u>

[ given ] 17 = 3n - 7

[ add 7 to both sides ] 24 = 3n

[ divide both sides by 3 ] 8 = n

Have a nice day!

I hope this is what you are looking for, but if not - comment! I will edit and update my answer accordingly. (ノ^∇^)

In physics, Boyle’s law states that if the temperature is constant, then the pressure, P, of a gas is inversely proportional to

VMariaS [17]

The constant of proportionality for this situation is 425

Step-by-step explanation:

When a quantity is inversely proportional with another quantity, then

the product of the two quantities is constant

1. If y is inversely proportional with x

2. Then y ∝ $\frac{1}{x}$

3. that mean y = $\frac{k}{x}$ where k is the constant of variation

4. Then xy = k

∵ In physics, Boyle’s law states that if the temperature is constant

∵ The pressure, P, of a gas is inversely proportional to the volume,

V, of the gas

∴ P ∝ $\frac{1}{V}$

∴ P = $\frac{k}{V}$

∵ The pressure of the gas in a cylinder is equal to 250 kilo pascals

∵ The volume of the container is 1.7 cubic meters

- Substitute these values in the rule of variation to find k

∴ 250 = $\frac{k}{1.7}$

- Multiply both sides by 1.7

∴ k = 425

The constant of proportionality for this situation is 425
