Answer:
i need the points
Step-by-step explanation:
Given:
- total number of masks= 200
- cost of 1 mask= Rs. 5
so, total cost fir 200 masks=
200×5
= 1000
therefore, Joe paid Rs. 1000 altogether.
The area of the parallelogram= length x width= 20 x 16=320 sq. in.
the area of the top triangle = 1/2 x bh=1/2 (20)(8)=80 sq. in.
together the areas total: 320+80= 400 sq. in.
Answer: 3 minutes
To solve this, I plugged 0.25 into the y value since it represents the amount of sand remaining. I then solved for the x value which gave me a value of 3. (I hope this helps)
