Answer:

2/3

Step-by-step explanation:

2nd term = 2/5

5th term = 16/135

Nth term for any series is given by [tex]a r^n-1[/tex]

where a is the forst term

r is the common ratio

for 2nd term

[tex]2nd \ term = ar^n-1 = 2/5\\2nd \ term = ar^2-1 = 2/5\\2nd \ term = ar= 2/5\\[/tex]

for 5th term

[tex]5th \ term = ar^5-1 = 16/135\\\\5th \ term = ar^4 = 16/135\\[/tex]

Since we have to eliminate a  and find r .

we can divide 5th term by second term

then we get the following equation

[tex]2nd term/ 5th \ term = ar/ar^4 = (2/5) / (16/135)\\=>1/r^3 = 2*135/5*16 \\=>1/r^3 = 27/8\\=>1/r = \sqrt[3]{27/8} \\=> 1/r = 3/2\\=> r = 2/3[/tex]

\

Thus, common ratio is 2/3.

Answer:

105 degrees

Step-by-step explanation:

The sum of the angles on a triangle must always equal 180 degrees. We know that two angles are 28 and 47, so the third angle must be 105.

28 + 47 + x = 180

75 + x = 180

75 - 75 + x = 180 - 75

x = 105

Answer:

105 degrees

Step-by-step explanation:

28+47=75

180-75=105

Answer:

I would use box-and-whisker plots to compare the two sets of prices. The plots will show the ranges, which is the difference least and greatest data points. Also, the medians will divide each set of data into 4 equal groups. Comparing these middle values and range of prices in each group will show how similar the prices are.

Answer:

2x - 5

Step-by-step explanation:

2x^3 + 4x = 2x(x^2 + 2)

-5x^2 - 10  = -5(x^2 + 2)

so the factors are  (2x - 5)(x^2 + 2).

Answer:

235.2

Step-by-step explanation:

147 * 1.60 -> this way is an all in one calculation but to double check you can take 60% of 147 (147 * .60 = x ) and add that value to 147 so... 88.2+147=235.2

Answer:

88.2

Step-by-step explanation:

So all you have to do is this 147 * .60 = 88.2

Answer:

2 < x

Step-by-step explanation:

7-2(x+2)<-4-3(1 - x)

Distribute

7 - 2x-4 < -4 -3 +3x

Combine like terms

3 -2x < -7 +3x

Add 2x to each side

3-2x +2x< -7+3x+2x

3< -7+5x

Add 7 to each side

3+7 <-7+7+5x

10 <5x

Divide each side by 5

10/5 <5x/5

2 < x

Answer:

R = 35.0

Step-by-step explanation:

We know tan theta = opp/ adj

tan R = r/s

tan R = 7/10

Take the inverse tan of each side

tan ^-1 tan (R) = tan ^-1 (7/10)

R =34.9920202

R = 35.0

Answer:

263

Step-by-step explanation:

Let the number = xyz

The 6 has a digit on its left and on its right. It must be the middle number.

y = 6, so the number is x6z.

The 2 is not the last digit. It must be the first digit.

x = 2, so the number is 26z.

The remaining digit — 3 — must be the last digit.

z = 3, and the number is 263.

The mystery number is 263.

A word problem is a verbal description of a problem situation. It consists of few sentences describing a 'real-life' scenario where a problem needs to be solved by way of a mathematical calculation.

For the given situation,

Let the three digit number be xyz.

The digits are 3,6,2.

The mystery number can be found as

Hence we can conclude that the mystery number is 263.

Step-by-step explanation:

-6x -6×7 = -4x-2 :

-6x -42 = -4x -2 : (+4x)

-2x -42 = -2 : (+42)

-2x = 40 (/-2)

Answer:

a = 9m

Step-by-step explanation:

You can take the volume of the water tank as the volume of a cube.

The volume of a cube with side a is given by:

V=a*a*a = a^3

To find the value of a you do a the subject of the formula:

a=(V)^{1/3}

You replace and obtain for a:

a = (729m^3)^{1/3} = 9m

hence, the rim a of the water tank is 9m

Answer: The side of the tank is 9 m.

Step-by-step explanation: A water tank is normally a cube, which means length, width and height has the same measure.

To calculate Volume of a cube:

V = length*width*height

Knowing that volume is 729 and assuming sides are x:

x*x*x = 729

x³ = 729

x = [tex]\sqrt[3]{729}[/tex]

x = 9

The volume is in cubic meters, so sides of the tank measures 9 m.

Answer:

78 apples for 12 pies

Step-by-step explanation:

we use 13 apples for 2 pies

she makes 12 pies

6x2 = 12 pies

so we do 13x6

13x6=78

78 apples for 12 pies :)

can i get brainliest

Answer:

13/2 = 6.5

12 x 6.5 = 78

? = 78

13/2 = 78/12

Step-by-step explanation:

13 apples ÷ 2 pies = 6.5 apples per pie

12 pies x 6.5 apples per pie = 78 apples for 12 pies

? = 78 apples for 12 pies

13/2 = 78/12

Answer: $22.12

Step-by-step explanation:

I just did the compound interest formula which is

starting amount * (1. interst rate) ^ number of years

example if you have 100$ and you want to know how much it is worth if it appretiates by 7% of a period of 20 years it would look something like this;

100 * (1.10) ^20 = 672.74$

but since you have to figure out what it was in 2008 which was exactly half way in the period you divide the exponent by half so your formula should be;

I know the answer is right because I asked my teacher and it's correct.

REAL EXAMPLE: 18 * (1.51) ^.5 = 22.12$

The amount should be $22.12.

= $22.12
