Jupiter has a diameter of about 88,695 miles (142,800 kilometers) which is more than 11 times the diameter of Earth. It’s volume is over 1,300 times the volume of Earth. This mean that Jupiter is so big that over 1,300 Earth could fit inside of it.
40 students
Explanation: 5/9 of 360 students is 200 students who did bring lunch. 360-200=160 students who bought lunch. You then subtract 200-160 which gives you.. 40
Answer:
x=5, -1
Step-by-step explanation:
set the equation equal to 0: 2x^2-8x-10=0
divide both sides by 2 to get x^2-4x-5=0
next factor your new equation to get (x+1)(x-5)
set those equal to zero
now you have x+1=0 and x-5=0
finally, solve for x by subtracting 1 and adding 5
now you have your answer x= 5 and -1
the value would be 2x10^7
Answer:
39
Step-by-step explanation:
Let x be tens place digit and y be units place digit.
Therefore, required number = 10x + y
On reversing the digits number so obtained = 10y + x
According to the given information:
10y + x = 10x + y + 54
10y + x - 10x - y = 54
9y - 9x = 54
9(y - x) = 54
y - x = 54/9
y - x = 6
y = x + 6...... (1)
Since, sum of the digits is 12.
Therefore, x + y = 12....(2)
From equations (1) & (2)
x + x + 6 = 12
2x = 12 - 6
2x = 6
x = 6/2
x = 3
y = x + 6 = 3 + 6 = 9...[from eqn (2)]
10x + y = 10*3 + 9 = 30 + 9 = 39
Thus, the required number is 39.
