Is the product of 12 and 3/4 more or less than 12? Please explain answer
denis23 [38]
Hello!!

So the product is when numbers or variables are multiplied together. So if we have 12 * 3/4 then that equals 12/1*3/4=(12*3)/4=36/4=9

So we can see that the product of 12*3/4 is less than 12. We can see this right from the start by noticing that to be at least 12, then 12 would have to be multiplied by at minimum 1 meaning 12*1=12 anything less than 1 would result in a lesser value than 12.

Hope this helps!! Any questions please just ask!! Thank you!!!

sharia has a full time job and earns 475$ each week but she starts looking for ways to increase her weekly earnings . sharia fin
Arlecino [84]

Answer:

12 hours

Step-by-step explanation:

Full time job:

Earning per week = $475

Part time job :

Earning per hour = $11

Number of working hours per week at per time job to increase weekly earning to atleast $600 ;

Let number of hours = h

Full time earning + earning per hour * (number of hours) ≥ 600

$475 + ($11 * h) ≥ 600

$475 + $11h ≥ 600

11h ≥ 600 - 475

11h ≥ 125

h ≥ 125 / 11

h ≥ 11.36

Hence, sharia will need to work for 12 hours per week

Two airplanes are are 1600 miles apart and heading toward each other at different altitudes. The first plane is traveling north
Elden [556K]

The planes will pass each other in 1.14 hours.

Why?

To solve the problem, we must remember that since both planes are heading toward each other, the speed to the calculations will be their combined speeds.

The speed will be:

Speed=PlaneA+PlaneB\\\\Speed=620mph+780mph=1400mph

Now, calculating the time, we have:

x=v*t\\\\1600mi=1400mph*t\\\\t=\frac{1600mi}{1400mph}=1.14hours

Hence, the planes will pass each other in 1.14 hours.

Have a nice day!

Stiviko's approved work plan included 4 technicians to create 200 web pages
jenyasd209 [6]

Answer:

10 pages per technician per day is the unit metric for the production work.

Step-by-step explanation:

Consider the provided information.

Stiviko's approved work plan included 4 technicians to create 200 web pages  over 5 days.

They can create 200 web pages over 5 days.

\frac{200}{5}=40

That means in one day they can create 40 pages.

There are 4 technicians who work, therefore the unit metric for the production work is: \frac{40}{4}=10

Hence, 10 pages per technician per day is the unit metric for the production work.
