In a certain chemical, the ratio of zinc to copper is 3 to 17. A jar of the chemical contains 340 grams of copper. How many grams of zinc does it contain?
It contains grams of .

Total amount of zinc in jar = 60 gram

Step-by-step explanation:

Given:

Total copper contain in jar = 340 grams

Ratio of zinc to copper in Jar = 3:17

Find:

Total amount of zinc in jar

Computation:

Total amount of zinc in jar = Total copper contain in jar[ratio of zinc / ratio of copper]

Total amount of zinc in jar = 340[3 / 17]

Total amount of zinc in jar = 1,020 / 17

Total amount of zinc in jar = 60 gram

(d)

step-by-step explanation:

given: the line in the graph passes through points (5,30) and (6,26).

then, the equation of line is:

now, put y=a(n) and x=n,

hence, option d is correct.

step-by-step explanation:

i think something is missing in your question because y-1=(x-12) would not pass through the point (-4,-3). because if you replace x by -4 your are supposed to find y=-3 which is not the case her. if you replace x by -4 you find =-15.

i assume the right equation is y-1=1/4*(x-12) because this one is passing through both your points (if you are interested to know how i found that out i can tell you).

in this equation if i replace x by -4 i find y=-3 and if i replace x by 12, i find y=1 so the line representing this equation is passing through those 2 points.

then the standard form of the equation is finding an expression of y in function of x

y-1=1/4*(x-12)

y=x/4-3+1

y=x/4-2

do you confirm there was a mistake in the question?
