If two pyramids are similar and the ratio between the lengths of their edges is 2 7 what is the ratio of their volumes?

The answer is 8:343.

Step-by-step explanation:

We can use Galileo's square cube law to calculate the ratio between two similar pyramids. The law is used to describe the change of the area or the volume of the shape when their dimensions increase or decrease:

V₁ and V₂ - volumes of pyramids,

l₁ and l₂ - the edges of pyramids.

Answer is 8:343

Step-by-step explanation:

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

answer: you need the equation in the question so i can answer it
