The figure denotes two semi-circles. Show that the ratio of the un-shaded region to the
shaded region in the figure is 5: 7.
​

the inequality is:

250c+180g≥950

step-by-step explanation:

let c denotes the number of days in a week   miyoko worked as a cryptographer.

and g denotes the number of days in a week she works as a geologist.

now we are given that she earns $250 for every day she works as a cryptographer,and earns $180 for every day she works as a geologist.

now miyoko's goal is to earn more than $950 this week.

hence, the inequality could be represented as:

250c+180g≥950

let m = monomial

let t = trinomial

so, m times t = t.

monomial times a trinomial = another trinomial.

66.666666667%

step-by-step explanation:

divide 150 by 100

divide 100 by 1.5

there you go!
