the school can only seat 50 students in every bus. If the school is planning on taking 360 students on a field trip. How many busses do they need. (show work) with independent variable dependent variable constant term and coefficient

Answers

so you would do 360/50
simplified you would get 36/5 this simplifies to about 7 and 1/5

so you would need 7 and 1/5 bus or 7.2 bus
but you can't have 1/5 buss so you would need to make the 1/5 into a 1 so
7+1=8
8 busses neede
50x = 360
x is the number of buses
x = 360/50 => 36/5
x = 7.2

Independent Variable: x
Dependent Variable: 360 (or y)
Coefficient: 50 (b/c of 50x)
I don't see a constant term, sorry

Is there a relationship between the area and perimeter of a rectangle?

Answers

Don't think so, area has nothing to do with perimeter.
Area you multiply the length and base , but perimeter you multiply length x width x height or also know as LxWxH.  ex. area. Length = 4. height = 2. 4 x 2 = 8. your area is 8. perimeter. length = 4. width = 2 . height = 3. 4x2x3=24. your perimenter is 24.

Solve for c in a+b+c=180

Answers

Answer:

c = -a - b + 180

Step-by-step explanation:

Isolate the c. Note the equal sign, what you do to one side, you do to the  other. Subtract a and b from both sides

a (-a) + b (-b) + c = 180 (-a) (-b)

c = 180 - a - b

c = -a - b + 180 is your answer

2 doctors is what percent of 25 doctors

Answers

To find that answer, you have to divide 2 by 25.

That is .08 or 8%

If you have the percent and want to find the nonpercent like 2 of 25, then you multiply .08 by 25 and you get 2.

Hope I helped!!!
- - Let's solve:

(2)/(25) *100=8

Your final answer is 8%
