Catalyst is also used that is generally sodium silicylate. So chemicals are a mixture of a dye (which gives color to light), catalyst, and diphenyl oxalate and chemical in gas vial is hydrogen peroxide. by mixing these chemicals we get a glow.

Which organization or agency assists the fire department by alerting the public of traffic incidents or evacuations?
MariettaO [177]

Media is the organization or entity that would help the fire department with incident scene security, crowd control, and explosives disposal.

Law enforcement is the organization or entity that would support the fire department with incident scene security, crowd control, and explosives disposal. Law enforcement forces respond to emergencies around the clock and operate under a paramilitary command structure. In most traffic situations, officers act alone and are taught to make unilateral command judgments. Fire and rescue services respond to emergencies around the clock and follow a well-defined command structure on the scene. The core constituency of traffic incident management consists of eight key disciplines: law enforcement, fire and rescue, emergency medical, transportation, towing and recovery, hazardous materials cleanup, public safety communications and dispatch, and traffic reporting.

For each of the following products, indicate whether you believe demand will be relatively price elastic or relatively price ine
insens350 [35]

Answer:

Note that goods that are considered in general have a broad demand and goods with broad demand are inelastic as there are no substitutes for them. Goods that are specific by nature have narrow demand and have elastic demand because consumers can switch to others if the price is increased slightly.

Hence, Mayonnaise in general, Washing machines and beer have inelastic demand as there are no close substitutes. The remaining three, namely, specific brand of mayonnaise, Chevrolet automobiles and Tesla automobiles have elastic demand as there are substitutes and consumers/users will switch to others if the price is no more favorable.

A tour group split into two groups when waiting in line for food at a fast food counter. The first group bought 8 slices of pizz
creativ13 [48]

Answer:

The cost of an slice of pizza is $3.94

Explanation:

Hi, we have to construct 2 equations with the information of the problem, the first one is " 8 slices of pizza and 7 soft drinks for $45.10".

8P+7D=45.10

And the second one, when "The second group bought 6 slices of pizza and 5 soft drinks for $33.34" is.

6P+5D=33.34

Where: P = pizza slices and D= soft drinks

We need to substract one equation from the other, but firs we need to equal one of the variables. In order to do so, we multiply our first equation by 5 and the second one for 7, therefore we get.

First equation

40P+35D=225.5

And the second one:

42P+35D=233.38

And now, we substract them and solve.

40P+35D-(42P+35D)=225.5-233.38

40P-42P+35D-35D=-7.88

-2P=-7.88

P=\frac{-7.88}{-2} =3.94

The cost of a slide of pizza is $3.94

In case you needed to find the cost of the soft drink, we just substitute P for 3.94 in any of the initial equations, that is:

8(3.94)+7D=45.1

7D=13.58

D=1.94

The cost of a soft drink is $1.94

Best of luck.

Alex_Xolod [135]

Answer: Lindsey's total investment in education is $18,000.

Since Lindsey's college will cost a total of $6000 per year for the next three years, her total investment in education will be  6000*3 = 18,000.

The $26000 per year that's given in the question is the value of Lindsey's earnings if she chose to work at the local mall. This is the gain Lindsey foregoes in each of the three years in order to learn, and represents her opportunity cost or alternate costs.
