In a certain chemical, the ratio is zinc to copper is 4 to 15. A jar of the chemical contains 570 grams of copper, how many zinc does it contain

zinc = 152 grams

Step-by-step explanation:

Ratio of zinc to copper = 4 : 15

Copper = 570 grams

zinc = x grams

Find x

Ratio of zinc to copper = x : 570

Equate both ratios

4 : 15 = x : 570

4/15 = x/570

Cross product

4 * 570 = 15 * x

2,280 = 15x

x = 2,280/15

= 152

x = 152 grams

zinc = 152 grams

3, 12, 48, 384, 1536, 6144, 24576, 98304

step-by-step explanation:

just keep timing it by 4.

in the attachment.   i didn't see your choices.   the word which means there is choices.

step-by-step explanation:

(x,y)

x tells you how much left or right you go from the origin

y tells you how much down or up you go from the origin

so for example (-3,2), you go left 3 and up twice. i denoted which of the ordered pairs is which in my graph.
