Answer:

Step-by-step explanation:

8 : 4 : 6

8 + 4 + 6 = 18

72 ÷ 18 = 4

8 : 4 : 6 = 32 : 16 : 24

32 × 16 × $\frac{1}{2}$ = 512cm²

Answer:

The correct answer option is H. 4374.

Step-by-step explanation:

We are given the following geometric sequence and we are to find its 8th term:

$\frac{2}{9}, \frac{2}{3}, 2,...$

Here $a_1=\frac{2}{9}$ and common ratio $(r) = \frac{\frac{2}{3} }{\frac{2}{9} } =3$ .

The formula we will use to find the 10th term is:

nth term = $a_1 \times r^{(n-1)}$

Substituting the values in the formula to get:

10th term = $\frac{2}{9} \times 3^{(10-1)}$

10th term = 4374

A wedding planner uses 72 ivy stems for 18 centerpieces when she arrives at the venue she realizes she will only need 16 centerp

beks73 [17]

Answer:

64 ivy stems

Step-by-step explanation:

To solve this problem we can use rule of three:

Firstly we had 72 ivy stems to use in 18 centerpieces, and know we have 16 centerpieces and want to know how many ivy stems we need to use, so:

18 centerpieces -> 72 ivy stems

16 centerpieces -> X ivy stems

18/16 = 72/X

X = 16*72/18 = 64

He needs to use now 64 ivy stems to maintain the ratio.

Which quadratic equation is equivalent to (x^2-1)^2-11(x^2-1)+24=0

Y_Kistochka [10]

Answer:

The correct answer is first option

u² - 11u + 24 = 0

When u = (x² - 1)

Step-by-step explanation:

It is given that,

(x² - 1)² - (x² - 1) + 24 = 0

To find the correct answer

Substitute u = x² - 1

The equation becomes,

u² - 11u + 24 = 0 Where u = (x² - 1)

Therefore the correct answer is first option

u² - 11u + 24 = 0

When u = (x² - 1)

Four cards are shuffled and placed face down in front of you. Their faces (hidden) display the four elements: water, earth, wind

Licemer1 [7]

Answer:

probability of winning is $\frac{2}{3}$

Step-by-step explanation:

As it is given , 4 cards are available, there are 4! mean total possible way of ordering is 24

following are the cases of loosing

1) first card is fire.

Thus there are 3! = mean 6 possible ways for particular ordering to occur.

2) If wind is first card and Fire is second. Then, There are 2! = 2 ways to occur.

Hence, the probabiIity of losing is given as $= \frac{6+2}{24}=\frac{1}{3}$

therefore probality of winning is $1 -\frac{1}{3}$

probality of winning is $\frac{2}{3}$
