A metal is made from copper, zinc and lead in the ratio 13:6:1 respectively. The mass of zinc is 90kg. Calculate the mass of the metal

52

Step-by-step explanation:

y

let the ratio of zinc be x

6x

mass of the zinc=90kg

6x=90

x=15

for other metals

copper=13x=13*15=195kg

lead=x=15kg

mass of whole metal=195+90+15=300kgStep-by-step explanation:

the red lines denote the population of the bacteria after 35 hours. that would be 2,409.24. the y-intercept is the blue line which is 800 because that is the starting point. the equation used to make the graph is 800(1.032)^h, where h is the number of hours.
