the number one bees that visit a plant is 500 times the number of years the plant is alive where T represents the number of year

ira [324]

500t represents the number of times bees visit the flower because if bees visit the flower 500 times for every year it is alive, and it was alive 5 years, then it would be 500 times 5. So 500t represents how to find how many times a bee would visit a particular plant.

Drag the tiles to the correct boxes to complete the pairs not all tiles will be used match the system of equations with their so

allochka39001 [22]

Answer:

Part 1) solution {(-5,8),(3,0)} ----> $y+12=x^{2}+x$ and $x+y=3$

Part 2) No solutions ----> $y-15=x^{2}+4x$ and $x-y=1$

Part 3) solution [(-2,5),(3,-5)] ---> $y+5=x^{2}-3x$ and $2x+y=1$

Part 4) No solutions ---> $y-6=x^{2}-3x$ and $x+2y=2$

Part 5) solution [(2,3),(8,9)] ---> $y-17=x^{2}-9x$ and $-x+y=1$

Part 6) solution [(-2,3),(7,-6)] ---> $y-15=-x^{2}+4x$ and $x+y=1$

Step-by-step explanation:

Part 1) we have

$y+12=x^{2}+x$ ----> equation A

$x+y=3$ ----> equation B

Solve by graphing

Remember that the solution of the system of equations is the intersection point both graphs

The solution are the points (-5,8) and (3,0)

see the attached figure N 1

Part 2) we have

$y-15=x^{2}+4x$ ----> equation A

$x-y=1$ ----> equation B

Solve by graphing

Remember that the solution of the system of equations is the intersection point both graphs

The system has no solutions, because there is no point of intersection between the two graphs

see the attached figure N 2

Part 3) we have

$y+5=x^{2}-3x$ ----> equation A

$2x+y=1$ ----> equation B

Solve by graphing

Remember that the solution of the system of equations is the intersection point both graphs

The solution are the points (-2,5) and (3,-5)

see the attached figure N 3

Part 4) we have

$y-6=x^{2}-3x$ ----> equation A

$x+2y=2$ ----> equation B

Solve by graphing

Remember that the solution of the system of equations is the intersection point both graphs

The system has no solutions, because there is no point of intersection between the two graphs

see the attached figure N 4

Part 5) we have

$y-17=x^{2}-9x$ ----> equation A

$-x+y=1$ ----> equation B

Solve by graphing

Remember that the solution of the system of equations is the intersection point both graphs

The solution are the points (2,3) and (8,9)

see the attached figure N 5

Part 6) we have

$y-15=-x^{2}+4x$ ----> equation A

$x+y=1$ ----> equation B

Solve by graphing

Remember that the solution of the system of equations is the intersection point both graphs

The solution are the points (-2,3) and (7,-6)

see the attached figure N 6

A light bulb consumes 600 watt-hours per day. How many watt-hours does it consume in 3 days and 18 hours

Lelechka [254]

Answer:

2250 watt-hours

Step-by-step explanation:

Okay, so we first need to find out how many watt-hours the light bulb consumes in 1 hours, so we need to divide 600 by 24 hours, which gives us a rate of 25 watt-hours per hour.

So if the light bulb consumes 600 hours per day, and it runs for 3 days, you multiply 600 by 3 to get 1800.

And because we know that it also consumes 25 watt-hours per hour, we multiply 25 and 18 together to get 450 hours.

Finally, you add 1800 and 450 together to get 2250 watt-hours.

Hope this helps :)

Jan ran a mile in 0.14 hours. Convert the hours into a fraction. hours

ANTONII [103]

0.14 can be converted to 14/100, which can be simplified to 7/50. (by dividing both sides of the fraction by 2 to simplify it.)
