a nurse worked from 8:15 am until 11:30 am and 12:30 am until 4:15 pm. estimate the total number of hours worked

1 answer:

4 0

Ok so lets work it out ( answer at the bottom in bold)

11:30 - 8 :15 = 3:15 ( 3 hours and 1 5 minutes)
and for the next part its a little trickky cause we are going from am to pm but we can work it out
so we know it will end in 45 because it takes 30 + 30 = 1 hour and it says 4: 15 so we know we need a 15 and 15 + 30= 45
so now we will put 45 to the side but we now instead of having 12:30 we have 1 :00 pm and 4:00 pm
4:00 - 1 : 00 = 3 pm and now we take the 45 and add it to the 3:00 pm so 3:00 + 45 = 3:45 pm
and now we add our 2 end results
3 :45 + 3:15 = 7 hours
The nurse worked 7 hours

A video game has 25 levels. At level one, a player has 5 points. Each additional level increases the player's points by 10. If

ozzi

Answer:

B. (3,25)

Step-by-step explanation:

x = level of the video game

y = number of points

At level 1, a player has 5 points.

At level 2, the player has 5 + 10 = 15 points

Therefore, we can use the function notation this way:

f(x) = 5x + 10

The only ordered pair given that is from this function is:

B. (3,25)

f(3) = 5 * 3 + 10

f(3) = 15 + 10 = 25

The remaining three don't represent this function.

over a season in a women's basketball league jackson scored 41 more points than the second highest scorer leslie. Together they

vlabodo [156]

First, you know that Jackson (let call her J) scored 41 more points than L (Leslie). What we don't know is how many points L scored so we can use a variable that will be 'x'.
So the equation will be J=41+x.
We also know that the total points is 1,189.
To find out what x is we first subtract 1,189-41. We then get 1,148.
We are now left with 2x and 1,148 so we divide 1,148 by 2 and get 574.
574=x so now we can plug that in.
J= 574+41
Jackson scored 615 points and Leslie scored 574 points

(You can use bar modeling to do solve this problem. An example of bar modeling is shown below.
