Answer:
- 326.6 square inches
- 3402 square feet
Step-by-step explanation:
The net will be a rectangle representing the lateral area. Its length will be 2π(4 in), the circumference of the box, and its height will be 9 in, the height of the box. On either side of that rectangle will be an 8-in diameter circle representing the ends of the box.
The total surface area is given by the formula ...
SA = 2πr(r +h)
For one box, the area is ...
SA = 2(3.14)(4 in)(4 in +9 in) ≈ 326.6 in² . . . . area of one box
__
There are 144 square inches in a square foot, so the area required for 1500 boxes is ...
(1500)(326.56 in²)/(144 in²/ft²) ≈ 3402 ft² . . . area of 1500 boxes
The answer is he is saving at a rate of 30$ per month. Idk how the other dude got 53i4
The equation is y=30x+130
Explanation:
It wants you to find the slope. So subtract the initial amount by the amount after 4 months.
250-130=120
Now divide it by 4 to get the slope.
120/4=30
Brainliest my answer if it helps you out
It would be 30 because when you add 5z to a -5z those cancel out so what you have left would be 20+10 and you would add those together and get 30.
