You need to fill a clay mold with 324 cubic in of clay. the base of the mold is 15 square inches. how high will the clay be once it is in the mold?
a. 20 in
b. 21.6 in
c.22.9 in
d. 25 in

Option B.

Step-by-step explanation:

we know that

The volume of the mold is equal to

where

B is the area of the base of the mold

h is the height of the mold

In this problem we have

substitute and solve for h

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

if you was gonna solve for a, a is a   < -12
