Find the least common denominator (LCD) of 7/9 and 5/6

AnnZ [28]

Answer: 18

Step-by-step explanation:

The least common denominator of $\frac{7}{9}$ and $\frac{5}{6}$ is going to be a multiple of 9 and 6. Let us list them out:

9: 9, <u>18</u>, 27, 36, 45, 54, 63, 72, 81, 90

6: 6, 12, <u>18</u>, 24, 30, 36, 42, 28, 54, 60

You can see I bolded and underlined 18. Why? This is the first common multiple of 9 and 6 so it is our least common denominator (LCD).

Irina18 [472]

The sum of the infinite geometric series is -288.

<h2>Given that</h2>

A finite geometric series with n = 4, a₁ = -144, and r = ½.

<h3>We have to determine</h3>

What is the sum of the infinite geometric series?

<h3>According to the question</h3>

The sum of the infinite is determined by the following formula;

$\rm S\infty = \dfrac{a_1(1-r^n)}{1-r}\\\\$

A finite geometric series with n = 4, a₁ = -144, and r = ½.

Substitute all the values in the formula;

$\rm S\infty = \dfrac{a_1(1-r^n)}{1-r}\\\\S\infty = \dfrac{-144 (1- \dfrac{1}{2}^4)}{1-\dfrac{1}{2}}\\\\S \infty = \dfrac{-144 \times \dfrac{15}{16}}{\dfrac{1}{2}}\\\\S \infty = -270$

Therefore,

The sum of the infinite geometric series is,

$\rm S = \dfrac{a_1}{1-r}\\\\S=\dfrac{-144}{1-\dfrac{1}{2}}\\\\S = \dfrac{-144}{0.5}\\\\S = -288$

Hence, the sum of the infinite geometric series is -288.

PLEASE HELP!!!<br> a<br> 300 cm<br> b<br> 60 cm<br> c<br> 20 cm<br> d<br> 45 cm

brilliants [131]

Answer:

45 cm

Step-by-step explanation:

Let length of the field in the drawing = x

80 : 120 :: 30 : x

Product of extreme = Product of means

80 * x = 120 * 30

$x = \frac{120*30}{80}\\\\x = 15 * 3\\x = 45$

Answer: Throughout the squares, you see mostly triangles.

Step-by-step explanation:

As you can see, theare are triangles within the squares on the above image. If you know that a^2+b^=c^2, you can apply this. Hope this helps.
