Answer:
1,498,454,000 sq. miles
Step-by-step explanation:
Volume of a sphere = 4/3 (3.14) r^3
So since the diameter is 1420 miles, the radius would be half.
V = 4/3 x (3.14) x 710^3
V=4.18666667 x 357,911,000
V = 1,498,454,054.5 but if you want it rounded to the nearest thousand then it'd be 1,498,454,000.
<h3>Point Y is the midpoint of segment XZ. Then value of x is 20</h3>
<em><u>Solution:</u></em>
Given that,
<em><u>Point Y is the midpoint of segment XZ</u></em>
XY = 2(3x +1)
YZ = 5x + 22
To find: Value of x
Since, Point Y is the midpoint of segment XZ,
Therefore,
XY = YZ
2(3x + 1) = 5x + 22
6x + 2 = 5x + 22
6x - 5x = 22 - 2
<h3>x = 20</h3>
Thus, value of x is 20
Answer:
£38,6267
Step-by-step explanation:
First year depreciation will be:
42800 * 0.(100-5) = £40,660
Second year worth after depreciation:
40660 * 0.(100-5) = £38,627
I hope I answered your question well.
Castel's average speed from the science museum to mountains is 20 km/h
<h3>A
verage speed</h3>
Let x represent Castel' average speed.
Sumalee left one hour later and caught up with Castel after two hours, Let us assume the distance covered is d:
For Castel:
For Sumalee:
- x + 10 = d / 2
- d = 2x + 20
3x = 2x + 20
x = 20 km/h
Therefore Castel's average speed from the science museum to mountains is 20 km/h

Answer:
2 =6
3= 9
4=12
5=15
Step-by-step explanation:
Formula is 3x
2 x 3= 6
3 x 3=9
4 x 3= 12
15/3= 5
