30 less than means -30
4 times a number means 4 times x or 4x
equal means =
14 is 14
-30+4x=14
add 30 boths ides
30-30+4x=14+30
0+4x=44
4x=44
divid by 4
4/4x=44/4
1x=11
x=11
18x^2+45x+27 is the answer
Eight ten-thousandths = 8*(1/10,000) = 8/10⁴ = 8 x 10⁻⁴.
Thirty-five million = 35*(1,000,000) = 35 x 10⁶
Therefore eight ten-thousandths of thirty-five million is
(8 x 10⁻⁴) * (35 x 10⁶)
= 280 x 10⁶⁻⁴
= 280 x 10²
= (2.8 x 10²) * 10²
= 2.8 x 10⁴
Answer: 2.8 x 10⁴
Proof.
For two dice, the number of favorable cases is 5: (6, 2);(5, 3);(4, 4);(3, 5);(2, 6); so the
probability is 5/36 =
30/216
For three dice, the number of favorable cases is 21: (5, 2, 1), (4, 3, 1) counted with all permutations
(so 6 2 = 12), and (1, 1, 6), (2, 2, 4), (3, 3, 2), counted with the distinct permutations (so
3 3 = 9). The probability is 21/216
So the more likely case is for two dice.
Area of a square: side²
200=side²
side=√200=14.14
Pythagoras therorem:
hypotenuse²=leg₁² +leg₂²
In this case:
hypotenuse=diagonal
leg₁=leg₂=side
Therefore:
hypotenuse²=(14,14 m)²+(14,14 m)²
hypotenuse²=200 m²+200 m²
hypotenuse²=400 m²
hypotenuse=√(400 m²)=20 m
The diagonal would be 20 m.
