I think it might be 7 don't know what answers you may have but its a guess
80,000.
To round up to the nearest ten thousand, we would see if the next lower place value has a amount either 5 or higher or 4 or lower.
If it’s five or higher, we round up.
If it’s four or lower, we round down.
We can see that the number in the ten thousands place is 8. The number in the place value after 8 is 2.
2<5 so we round down.
The answer is 80,000.
Hope this helps!
For 1. To estimate how many sports cards Alberto had, you would round each number to the nearest ten, so 318 would become 320. 273 would then become 270. You would then add those two and would get 590. So, Alberto had 590 sports cards (estimated). If you were looking for the actual answer (not estimated) , you would get 591.
The best design for Camille is the one in which the area matches the total of material she wants to use for each pillow.
<h3>What should Camille consider for her design?</h3>
Camille's main restriction is the material per pillow since she needs every pillow to use only 36 inches of material. Due to this, she needs to make sure the design meets this requirement.
<h3>How to determine how much material each design requires?</h3>
The best method for this is to calculate the area of the design by using the sides. Here are the most common formulas:
- Triangular design: Base x height/ 2
- Squared or rectangular design: side x side
- Circular design: A = π r²
Based on this, the best design is the one that adjusts to the material available.
Note: This question is incomplete because there is no information about the designs; due to this, I answered it based on general knowledge.
