Mathematics
1 answer:
lbvjy [14]3 years ago
3 0

Answer:

You can always compare to cost together but the big thing to look for is that you could be spending less for more on a product or the other way around, spending more for less product. you always want to go with the product that you are spending less money to get more product out of it.

Step-by-step explanation:

for example, say you are buying a pack of pencils, there is a pack of

10 pencils for 5 dollars

and

50 pencils for 10 dollarsthan

you would want to buy the second pack of pencils because you are getting each pencil for 50 cents rather than 2 dollars for each pencil in the first pack.

I'm confused. Can someone help me out with this problem step-by-step using the P = 2L + 2W formula?
german

We can't use P = 2L + 2W because  the sides have different lengths.

P = a + b + c + d

a = x

b = 2x

c = 2x - 2

d = x + 5

P = x + 2x + (2x - 2) + (x + 5)

P = <u>x + 2x + 2x</u> - 2 <u>+ x</u> + 5

P = 6x + 3

if x = 4:

P = 6 · 4 + 3

P = 24 + 3

P = 27

How many students were surveyed about their mode of transportation to school?
AlekseyPX

Answer:

Total number of students surveyed about their mode of transportation to school is 400.

Step-by-step explanation:

Here, given student who uses car as their mode of transport = 120 students

We have to find the total number of students who are surveyed.

Also, since complete circle represents 100% of data,

Total students who uses at least one mode of transport out of foot, bicycle, bus or car let it be x students.

Total percentage of students that uses bus, bicycle and on foot = (20 +15+35)% = 70%

Thus, percentage of students that uses car = 100 - 70 = 30%

Thus, 30 % of total students = 120

Mathematically,  30% of x = 120

Solving for x, we get,

\frac{30}{100} \times x=120

\Rightarrow x=120 \times \frac{100}{30}

\Rightarrow x=400

Thus, total number of students surveyed about their mode of transportation to school is 400.
