If the red square has an area of 200 square centimeters and the green square has an area of 60 square centimeters, then was is the area of the yellow square?

140

Step-by-step explanation:

You want the area. You do not have to take the square root. First of all you have to assume this is a right angle triangle.

c^2 = b^2 + a^2

c^2 = 200

b^2 = 60

a^2 = ?

200 = 60 + a^2

200 - 60 = a^2

a^2 = 140

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
