Find the perimeter when 106 triangles are put together in the pattern shown below. Assume that all triangle sides are 1 cm long.
Answers
Using an arithmetic sequence, it is found that the perimeter when 106 triangles are put together is of 108 cm.
What is an arithmetic sequence?In an arithmetic sequence, the difference between consecutive terms is always the same, called common difference d.
The nth term of an arithmetic sequence is given by:
[tex]a_n = a_1 + (n - 1)d[/tex]
The perimeter of a figure is the sum of the outer sides of the figure. Hence, considering that all sides are 1 cm long, we have that:
When there is one triangle, the perimeter is of 3 cm.When there are two triangle, the perimeter is of 4 cm(1 + 1 + 1 + 1 = 4), as shown in the figure given at the end of the answer.When there is three triangles, the perimeter is of 5 cm.When there is four triangles, the perimeter is of 6 cm.Hence the first term and the common difference are given as follows:
[tex]a_1 = 3, d = 1[/tex]
Hence the 106th term of the sequence is:
[tex]a_{106} = 3 + 105 = 108[/tex]
The perimeter when 106 triangles are put together is of 108 cm.

A news reporter in a city with several carbon-emitting power plants wanted to see whether local temperatures matched trends in global climate change. She
focused on the four coldest months of the year.
The table shows local temperature data from November through February for the two consecutive cold seasons checked by the reporter.

The mean temperature change between the two cold seasons is (b) went up by 0.3°
How to compare the mean values of both seasons?The given parameters are:

Nov: 64.2Dec:56 8Jan;48.3Feb: 55.1The mean is calculated as
Mean = Sum/Count
So, we have
2011 - 2012 mean = (61.1 + 51.9 + 53.6 + 56.5)/4
Evaluate
2011 - 2012 mean = 55.8
Also, we have
2012 - 2013 mean = (64.2 + 56.8 + 48.3 + 55.1)/4
Evaluate
2012 - 2013 mean = 56.1
The difference in these mean values are
Difference = 56.1 - 55.8
Evaluate
Difference = 0.3

How to solve the given equationGiven data
64^1/2 x 27000^2/3 all over2^-4 x 3^0 x 5^2
Rewriting gives:
( 64^1/2 x 27000^2/3 ) / ( 2^-4 x 3^0 x 5^2 )
the solution; we first note that
64^1/2 = √64 = 8
27000^2/3 = ∛27000^2 = 900
3^0 = 1
2^-4 = 1 / 2^4 = 1 / 32
5^2 = 25
substituting gives:
= ( 8 * 900 ) / ( 1/32 * 1 * 25)
= 7200 / 25/32
= 7200/25 * 32
= 288 * 32

The probability of spinner pointer not landing on green is equal to 2/3 .
As given in the question,
Total colors in the spinner is equal to 6
Each color is 2 times
Total number of colored region =6
Number of green region = 2
Probability of pointer landing on green color region denoted by P(G)
Probability is
=(Total number of favourable outcomes) / (Total number of outcomes )
⇒P(G)=2/6
⇒P(G) =1/3
Probability of pointer not landing on green P(G') =1-P(G)

In the given statement is
To find the midpoint of the line segment joining the pair of points
G(1,-1,6) and H(1/5,-2/5, 2)
Midpoint:
The coordinates of the midpoint of a line segment are the average of the coordinates of the end points.
m = (A +B)/2
If we are given three points and we wish to find the midpoint of those points, we need to use the midpoint formula m =([tex]\frac{x_{1}+x_{2} }{2} , \frac{y_{1}+y_{2} }{2} , \frac{z_{1}+z_{2} }{2}[/tex] )
where:
(x1 , y1 ,z1) are the coordinates of the first point:
(x2 , y2 , z2) are the coordinates of the second point:
Now, We are given the three points G(1,-1,6) and H(1/5,-2/5, 2)
Solving for the midpoint , we have,
m = ([tex]\frac{1+\frac{1}{5} }{2} , \frac{-1+(\frac{-2}{5} )}{2} , \frac{6+2}{2}[/tex])
m =(6/10 , -7/10 , 4)

times the mass of Mercury is the mass
of Jupiter?
Answers
The mass of the planet Mercury is 1.74 × 10⁻⁴ kg time the mass of the planet Jupiter.
Mass of Mercury = 3.3 × 10²³ kg
Mass of Jupiter = 1.9 × 10²⁷ kg
We need to find that how many times the mass of Mercury is the mass
of Jupiter.
For this, we will divide the mass of mercury with the mass of Jupiter.
So, we get that:
= ( 3.3 × 10²³ kg ) ÷ ( 1.9 × 10²⁷ kg )
Solving the expression by using the properties of exponents, we get that:
= 1.74 × 10⁻⁴ kg.
Therefore, we get that, the mass of the planet Mercury is 1.74 × 10⁻⁴ kg time the mass of the planet Jupiter.
