A school is taking 388 students on a field trip to the zoo, and they can rent buses that hold 30 students for $895 each or vans that hold 15 students for $450 each how many buses would it take to get everyone to the zoo?

how many vans would it take to get everyone to the zoo?

would it be cheaper to rent the buses or the vans? why?

~~~~~~~~~~~~

please get this finished soon, it's due homework for tomorrow.

whilst this is being answered, I'm going to be doing other homework, so good luck answering this one

It would take 13 buses to get everyone to the zoo

It would take 26 vans to get everyone to the zoo

It would be cheaper to rent buses

Step-by-step explanation:

The given is:

- A school is taking 388 students on a field trip to the zoo
- They can rent buses that hold 30 students for $895 each
- They can rent vans that hold 15 students for $450 each

We need to find how many buses it would take to get everyone to the zoo, how many vans it would take to get everyone to the zoo, and would it be cheaper to rent

∵ The number of students is 388

∵ Each bus can hold 30 students

- Divide the number of students by 30 to find the number of buses

∴ The number of buses = 388 ÷ 30 = 12.92

- They must to rent 13 bus to hold all the students

∴ The number of buses is 13

It would take 13 buses to get everyone to the zoo

∵ The number of students is 388

∵ Each van can hold 15 students

- Divide the number of students by 15 to find the number of vans

∴ The number of vans = 388 ÷ 15 = 25.87

- They must to rent 26 vans to hold all the students

∴ The number of vans is 26

It would take 26 vans to get everyone to the zoo

Let us find the cost of rent of the buses and vans to find which of them is cheaper

∵ The cost of rent of each bus = $895

∵ The number of buses = 13

∴ The cost of rent the buses = 13 × 895 = $11635

∵ The cost of rent of each van = $450

∵ The number of vans = 26

∴ The cost of rent the buses = 26 × 450 = $11700

∵ $11635 < $11700

∴ The cost of rent the buses < the cost of rent the vans

∴ The buses is cheaper than the vans

It would be cheaper to rent buses

Identify the slope and y-intercept of the graph of the equation. y=4x+3

Answer:

slope = 4

y-intercept = 3

Step-by-step explanation:

Note the slope-intercept form: y = mx + b

x & y is found inside the point (x , y).

m is the variable for the slope.

b is the variable for the y-intercept.

Find the corresponding number for the corresponding variable.

slope = m = 4

y-intercept = b = 3

~

Answer: the slope is 4 and the y intercept is 3. Hope this helps!

The formula to find a certain number in an arithmetic sequence is an=a1+d(n−1) . Solve for n.

an−a1/d+1=n

1−d/an+a1=n

1−an−a1/d=n

an+a1/d+1=n

Answer:

(an -a1)/d +1 = n

Step-by-step explanation:

Undo what is done to n, in reverse order. When evaluating this expression, you ...

- subtract 1 from n
- multiply the difference by d
- add a1

When you undo these, you get ...

... an -a1 = d(n-1) . . . . . . subtract a1

... (an -a1)/d = n - 1 . . . . divide by d

... (an -a1)/d +1 = n . . . . add 1

Please note the use of parentheses in the answer here. These identify that the difference (an -a1) is what is divided by d. None of the offered answers has these parentheses, nor are they typeset in a way that would indicate the intent to divide (an -a1) by d. As given, none of the offered answers is correct.

Determine whether the study described is a randomized experiment or an observational study. A wellness instructor wants to determine the effect of fitness class types on body fat composition. She measures the body fat of 100 fitness class participants before randomly assigning the participants to a class of yoga, Zumba, Pilates, or Tae Bo. She measures the body fat of each participant during the last week of classes. Choose the correct answer O Randomized experiment O Observational study

Answer:

Observational study

Step-by-step explanation:

Observational study is a research taken to get an inference or conclusion on a particular study.

A wellness instructor wants to determine the effect of fitness class types on body fat composition. the 100 participants are randomly assign to different class of yoga and there performance are noted.

the performance of the participant will be used to draw an inference on the effect of different fitness class on body weight.
