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.

hmm tak

Step-by-step explanation:

ja myślę że to bendzi bardzo trudniej powiedział bym raczej nie to bendzi samy proszę

option c) graph of line going through 1, 4 and 3, 10

step-by-step explanation:

let y equal to margo's coin collection

let x equal to number of years

at the begining x=0, y=1 → point=(x,y)→point=(0,1)

she adds 3 coins per year, then y=1+3x

at x=1, y=1+3(1)=1+3→y=4→point=(x,y)→point=(1,4)

at x=3, y=1+3(3)=1+9→y=10→point=(x,y)→point=(3,10)

the graph of line going through (1, 4) and (3, 10), then the option c is the correct.
