<u>Answer:</u>
The given statement is False statement
<u>Explanation:</u>
We are given that Jaime has blown out a number of candles equal to his age on each of his birthday till now and he is 9 years old now so the total number of candles blown by him all his life is given by the
arithmetic series
1 + 2 + 3 + 4 + 5 + 6 + 7 + 8 + 9 and
not the arithmetic series
0 + 1 + 2 + 3+ 4+ 5+ 6+ 7+ 9 as given
so the given statement is false.
1) 0.000006 In scientific notation = 06x10^-6
2) 5400000. In scientific notation = 5.4x10^6
3) 60 In scientific notation = 6x10^1
4) 0.009 In scientific notation = 9x10^-3
Answer:
x =4
Step-by-step explanation:
sum of angles in a triangle = 180
(equilateral triangle) all sides are equal
180 ÷ 3 = 60
10x+20 =60
10x = 60 - 20
10x = 40
10x ÷10 = 40÷ 10
x = 4
To find the perimeter, you need the lengths of all 3 legs,
and then you add them up.
Can you find the lengths of the other 2 sides of that triangle ?
Here are a couple of factoids I learned in 1954 and I never forgot:
In a 30°- 60°- 90° right triangle . . .
-- the side opposite the 30° angle (the shorter leg)
is 1/2 the length of the hypotenuse,
and
-- the side opposite the 60° angle (the longer leg)
is (1/2 the length of the hypotenuse) times (√3).
If you have a 30°- 60°- 90° triangle and you know the length
of any one side, then you can find the lengths of the other
two sides with these amazing factoids.
