It’s a meteor When meteoroids enter Earth's atmosphere (or that of another planet, like Mars) at high speed and burn up, the fireballs or “shooting stars” are called meteors. When a meteoroid survives a trip through the atmosphere and hits the ground, it's called a meteorite.
1. 6.25 x 10^0
2. 8.07 x 10^-1
Answer:
81
Step-by-step explanation:
double digit numbers begin at 10 and end at 99
10 → 19 has 10 double digits
20 → 29 has 10 double digits
and so on up to 90 → 99
that is there are 90 double digits from 10 → 99
double digits with same value are 11, 22, 33, 44, 55, 66, 77, 88, 99
that is 9 double digits with the same value
Then double digits with different values = 90 - 9 = 81
12x > 9(2x-3)-15
distribute the 9
12x > 18x-27 -15
combine like terms on the right side
12x > 18x-42
subtract 18x from both sides
-6x > -42
divide both sides by -6
x = -42 / -6 = 7
x >7
This the concept of algebra, the question requires us to find the ages of the three kids. This means we have three variables say x,y and z to represent the
ages of the kids. From the information given we have been told that the product of their ages is 72, we haven't been told what their sum is.
Since we have been given 3 variables we need to have at least 3 equations to solve for the variables. From the information we cannot formulate 3 equations because we lack inadequate information.
Therefore we conclude that Matt was right<span />
