John is putting on sunscreen. He uses 3 ml to cover 45 square cm of his skin. He wants to know how many milliliters of sunscreen (g) he needs to
cover 240 square cm of his skin. He assumes the relationship between
milliliters of sunscreen and area are proportional. How many milliliters of
sunscreen does John need to cover 240 square cm of his skin? (Only write
in the number.) *

hope this .

percentage - 25%

probability - 0.25

we know,

total amount of students in class = 20

total boys = 10

total girls = 10

no of girls who wear glasses = 10/2 = 5

probability of choosing a girl with glasses is =

number of girls wearing glasses/total number of students in the class = 5/20

thus, percentage of selecting a girl wearing glasses will be

= 5/20 × 100

= 5 × 5

25%

therefore,

probability will be 0.25

pls mark as brainliest

you can't solve x because it is 2 linear equation and you only have one equation

step-by-step explanation:

one of the most important purposes of surface treatment is to alter surface properties according to the requirement of specific applications. for example, hydrophobic coating has been utilized on windshield and eyeglasses. gold atom monolayer on substrate has become a popular surface bioconjugation strategy.
