Answer: sun
Step-by-step explanation:
cause I said
Answer:
Well I figure you would use a ratio. we are given one when comparing 240 lbs to 180 calories for each mile:
240lbs/180calories = 1 mile
we.are.given another when saying a person. burns 36 calories in 1 mile. we don't know weight so we will say x lbs:
x/36calories = 1 mile
since they both equal 1 mile we know they are equal:
240/180 = 1 = x /36
we can get rid of the 1 in between and say:
240/180 = x/36
let's reduce first fraction
8/6 = x/36
cross multiply:
8*36 = 6x
divide both sides by 6
8*6 = x
x = 48

Answer:
c sqrt( ( x2-x1) ^2 + ( (y2-y1) ^2)
Step-by-step explanation:
The distance formula is
d = sqrt( ( x2-x1) ^2 + ( (y2-y1) ^2)
It is the difference between the coordinates. It is based on the Pythagorean theorem
Answer:
Step-by-step explanation:
- Cost of a bottle of water = 10
- Cost of pizza = 60
- Total amount = 120
- Number of water bottles = x
<u>Equation:</u>
- 10x + 60 = 120
- 10x = 120 - 60
- 10x = 60
- x = 60/10
- x = 6
Answer:
Quota sampling
Step-by-step explanation:
Quota sampling is a type of sampling method in which a representative data is collected from a group. It is a non probability based sampling method, a type of stratified sampling. Quota sampling is required when researchers are working with limited time and are without a sampling frame. Quota sampling method helps to determine the characteristics of a subgroup under research. It is an highly accurate method of sampling.
