Assuming that the meteor crater forms a hemisphere, the formula for the surface area of the crater would be 2(pi)(radius^2). Set the crater equal to the formula for a hemisphere and substitute pi for 22/7 and you’d get 9687 = 2(22/7)(radius^2). Do some quick magic on the calculator to simplify and you end up with about 60,889.71 = radius^2. Take the square root from both sides and you get 246.8 when rounded. That should be the length of the radius, and so to find the diameter, just multiply that by 2 to get 493.5. Now I don’t really know what shape you mean by meteor crater, so we’re just assuming here that you mean half of a sphere, or a hemisphere. Don’t know if this is what you’re looking for, so good luck.
Answer:
40.6 inches
Step-by-step explanation:
The plant's initial height is 7 inches tall.
It grows 1.3 inches each day for 27 days. This means that after 27 days, it must have grown an extra:
1.3 * 27 = 35.1 inches
It must have grown an extra 35.1 inches after 27 days. Therefore, its new height after 27 days is:
7 + 35.1 = 42.1 inches
The plant then begins falling over 0.5 inch for the next 3 days. After 3 days, it must have fallen over by a height:
0.5 * 3 = 1.5 inches
Therefore, after 30 days, the plant's new height is:
42.1 - 1.5 = 40.6 inches
The plant's height after 30 days is 40.6 inches
Tan(35)=x/12
.7=x/12
12*.7=x
x=8.4
Answer: They can order from 0 to 449 bars, but no more.
Step-by-step explanation:
Given: The school band is ordering health bars to sell for a fundraiser. The company that sells the bars charges $0.40 per bar plus $20.00 for shipping regardless of the size of the order. The band must spend less than $200.00 on bars for the fundraiser.
The inequality below relates x, the number of bars that could be ordered, with the shipping costs and their spending requirements.
To solve for x, subtract 20 on both sides, we get
Divide 0.40 on both sides, we get
......... → the number of bars that could be ordered, with the shipping costs and their spending requirements must less than 450.
Thus, they can order from 0 to 449 bars, but no more.
