Answer: 20%

Step-by-step explanation:

Rule of 3, let's put the money on the left and the percentage on the right of the chart.

$\frac{60.00}{72.00}=\frac{100}{x}$

$x=\frac{72*100}{60} \\x=120$

Calculate the difference.

$120-100=20$

Find the oth term of the geometric sequence 9, -18, 36, ...

Sphinxa [80]

Answer:

2304

Step-by-step explanation:

Given :-

A geometric sequence is given to us which is 9 , -18 , 36.

And we need to find out the 9th term of the sequence. Here firstly we should find the Common Ratio and then we can substitute the respective values in the formula to find the nth term of a geometric sequence .

Common Ratio :-

$:\implies$ CR = -18÷ 9 = -2

The 9 th term :-

$:\implies$ T_n = arⁿ - ¹

$:\implies$ T_9 = 9× (-2) ⁹ - ¹

$:\implies$ T_9 = 9 × (-2)⁸

$:\implies$ T_9 = 9 × 256

$:\implies$ T_9 = 2304

Hence the 10th term is 2304.

dlinn [17]

9514 1404 393

Answer:

10) C 4/9

11) B 24

Step-by-step explanation:

10) The area ratio is the square of the ratio of side lengths. The ratio of side lengths is ...

RS/LM = 6/9 = 2/3

Then the area ratio is ...

(2/3)² = 4/9

11) Using the result of question 10, the area of ∆RST is ...

(4/9)(54 in²) = 24 in²
