Jack received $75 for his birthday. He spent 25 on a new baseball glove, $45 on a pair of new shoes, and $5 on digital music. a
A. what proportion of his birthday money went towards new shoes? Express the value as a simplified fraction period then, convert the fraction to a percent. show you work

B. What proportion of his birthday money went toward music? Express the value as a simplified fraction. Then, convert the fraction to a decimal. Round the decimal to the nearest hundredths or indicate it is repeating. show your work

C. bite the ratio of money Jack spent on music to money Jack spent on shoes. simplify your answer period what is the ratio mean? what fraction is equivalent to the ratio

A) Fraction = 3/5, Percentage = 60%

B) Fraction = 1/15 , Decimal = 0.083333 ≈ 0.08

C) Ratio = 1:9, Fraction = 1/9

Step-by-step explanation:

A) The total amount of money Jack received = $75

Jack's spent on shoes = $45

The proportion he spent on shoes

= $45/$75

= 3/5

Converting this fraction to percentage

= 3/5 × 100% = 60%

B.What proportion of his birthday money went toward music?

The total amount of money Jack received = $75

Jack's spent on music = $5

The proportion he spent on music

= $5/$75

= 1/15

Converting this fraction to decimal

= 1/15 = 0.0833333333

It is a repeating decimal.

Approximately to the nearest hundredth = 0.08

C. Write the ratio of money Jack spent on music to money Jack spent on shoes.

The ratio of money spent on music to the ratio of my money spent on shoes

Music : Shoes

$5 : $45

1:9

The fraction that js equivalent to the ratio is 1/9

introduction, methodology, results, discussion

step-by-step explanation:

an observational study is one which consists of actual observation to record data and then analyse the data.

there are a number of factors that should be analyzed before starting an observational study.

the main four factors are:

i) introduction:   this should be analysed to check whether the purpose of the study is correctly established and the data recorded are appropriate for the study

methodology:   the method of collecting the data, such as whether randomly selected, and whether sample size matches with the population to be studied, whether questions asked are easy to answer by common men, etc.

results: then results such as summary of data with comments should be studied thoroughly

discussion:   the last is the discussion, this can be either by management people or persons who are all interested , etc.

hello :

70y^8 + 30y^6 = 2 ( 35 y^8 + 15y^6)

the lenght is : 35 y^8

the width is : 15y^6
