A construction worker needs to determine the volume of a sandplle in a construction yard, as shown. A line along the surface of the sandpile from the ground to the top of the sandpile makes a 40° angle with the ground at point R.

• The length of the slant side of the sandpile, RT, from the ground to the top of the sandplle Is 20 meters.

What is the volume of the sandpile, to the nearest cubic meter? Show your work and explain how you determined your answer.

Enter your answer, your work, and your explanation in the box provided.

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

b. 1.25 hr

step-by-step explanation:

if you have a constant speed of 60 mph, then you have a ratio between 60 mi. to 1 hr. dividing both sides by 60 we get the ratio

1 mi. to

then mult. both sides by 75 we get the ratio

75 mi. to

simplifying we get

75 mi. to

or 1.25 hr.
