A construction company is digging a hole for a swimming pool. The whole will be 12 yards long, 7 yards wide, and 3 yards deep. How many cubic yards of dirt will the company need to remove?

the company will need to remove 252yd³ cubic yards of dirt

Step-by-step explanation:

a hole for a swimming pool has a rectangular prism shape

We know that the formula to calculate the volume of a rectangular prism is width by height by length.

depth we will call height

w = width

h = height

l = length

w * h * l = v³

we replace the values we know

7yd * 3yd * 12yd = 252yd³

the company will need to remove 252yd³ cubic yards of dirt

x^6

step-by-step explanation:

this is correct because:

x-6=0

0*x=0

so

x^6

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
