Answer:
x ≤ 63
Step-by-step explanation:
x/3-10 ≤ 11
Opposite of -10 is addition, 10+11= 21
Opposite of x/3 is multiplication 3, 21*3= 63
Answer:
The area of land is 0.067 million squared miles.
Step-by-step explanation:
The shape of a planet is sphere.
The surface area of a sphere is .
Given that, the radius of the planet is approximately 4012 miles.
Total surface area of the planet is
= 202,351,5224.6 squared miles
=0.202 million squared miles
of the plane surface is covered by water.
of the plane surface is covered by land.
The area of land is =
= 0.067 million squared miles
Answer:
The third one
Step-by-step explanation:
To find the middle you have to put the numbers from least to greatest. You have 27 and 31, add them together you get 58. Now you divide 58 into 2 and answer is 29. (This one is to figure out the median)
Answer:
Step-by-step explanation:
The circumference of a circle is the distance around the circle.
The formula for determining the circumference of the circle is expressed as
Circumference = 2πr
If the circumference of the inner circle is 44ft, the radius of the inner circle would be
2πr = 44
2 × 3.14 × r = 44
r = 44/6.28 = 7
The radius of the outer circle would be 7 + 3 = 10ft
Therefore, the circumference of the outer circle would be
2 × 3.14 × 10 = 62.8 ft
The difference in the circumference of the inner circle and the outer circle is
62.8 - 44 = 18.8 ft
