The chance is 3/5 that the light will be green.

Added together the total seconds for the traffic light to complete the cycle is 120 (38+72 (1 min and 12 sec) +10.

And the green light proportion is: 72/120

We simplify by dividing by 12, which is a factor and we get: 6/10 that simplifies to 3/5.

Hope this helps!

Renata and her family go through an average of more than 15 cans of sparkling water each day. They buy cases of 24 cans at $3.50
kaheart [24]

Answer: The inequality required to express the above condition is   x     ≥    18.75

Step-by-step explanation:Renata and her family go through an average of more than 15 cans of sparkling water each day.

The number of cases of 24 cans of sparkling water.

We can take the number of cases to be x.

Each case is said to cost $3.50.

An inequality for the number of cases that Renata's family go through in 24 days can be written as

      x ≥            ⇒     x    ≥            ⇒   x ≥     18.75

Therefore the inequality required to express the above condition is

x     ≥    18.75

The price of tiling a room varies directly as the size of the room. Sam is laying tile in his kitchen. If the tiling costs $4,22
stiv31 [10]

Answer:

<h3>The answer is option A</h3>

Step-by-step explanation:

Let the price of the room be p

Let the size of the room be s

To find the size of a kitchen that costs $3,824.00 we must first find the relationship between them

The statement

The price of tiling a room varies directly as the size of the room is written as

<h3>p = ks</h3>

where k is the constant of proportionality

when

p = $4,224.00

s = 264 square feet

Substitute the values into the expression to find k

That's

4224 = 264k

Divide both sides by 264

k = 16

So the formula for the variation is

<h3>p = 16s</h3>

when

p = 3824

s =  \frac{p}{16}

s =  \frac{3824}{16}

s = 239

The final answer is

239 square feet

Hope this helps you
