Answer:
B, and i don't for the second one
Step-by-step explanation:
5 /8 / 3/10 = 5/8 * 10/3 = 50/24 = 25/12 or 2 1/12
The more precise your length and width are, the more precise your area <span>measurement will be. Take this as example:
</span>width = 9.3045 mm
<span>length = 8.023 mm
</span><span>
Let's first round up:
width = 9.3 mm
length = 8 mm
Area = 9.3*8 = 74.4 mm
But if you are more precise with the width and length:
</span>width = 9.3045 mm
<span>length = 8.023 mm
</span>Area = 9.3045 * 8.023 = <span>74.6500035 mm
The more precise your length and width are, the more precise your area is. Also, as you can see t</span>he more precise your length and width are, the more your area will increase and will be more accurate.<span>

r · 7 ≤ 21 [r multiplied by 7 is less than or equal to 21]
7r ≤ 21
[If you wanted to solve it]
7r ≤ 21 Divide 7 on both sides to get "r" by itself
r ≤ 3
H=10 because u subtract 4 from30 and then divide by 3
