Answer:
You will need 1400 cm² of paper
Step-by-step explanation:
When you wrap a gift, you wrap around the entire object. We need to find the total surface area of the prism. A rectangular prism has two rectangular faces on the end. The area of one of those faces is Height (of the prism) times Width.
Rectangular prisms also have 4 sides which are composed of rectangles. The area of one of those rectangles is length (of the prism) by the width.
Now we just need to sum up all of those areas.
Step-by-step explanation:
okay so -25 • -9 = 9+10
225 = 9+10
225 = 19
19. 19
= 11.8
Answer:
Explanation:
Translate every verbal statement into an algebraic statement,
<u>1. Keith has $500 in a savings account at the beginning of the summer.</u>
<u>2. He wants to have at least $200 in the account by the end of summer. </u>
<u />
<u>3. He withdraws $25 a week for his cell phone bill.</u>
<u />
- Call w the number of weeks
<u>4. Write an inequality that represents Keith's situation.</u>
- Create your model: Final amount = Initial amount - withdrawals ≥ 500
With that inequality you can calculate how many week will pass before his account has less than the amount he wants to have in the account by the end of summer:
That represents that he can afford spending $ 25 a week during 12 weeks to have at least $ 200 in the account.
