Answer:

1/9

Step-by-step explanation:

The possible choices 2,3,4

odd numbers: 3

P (odd number) = number of odd numbers /total

= 1/3

Then we spin again

The possible choices 2,3,4

We want a 3: 3

P (3) = number of 3's /total

= 1/3

Since the first spin did not affect the second spin

P(odd, then 3) = P(odd) *P( 3)

= 1/3* 1/3

=1/9

A rectangular patio is 9 ft by 6 ft. When the length amd width are increased by the same amount, the area becomes 88 sq ft. Ging

SpyIntel [72]

( 6 + x)(9 + x) =88

54 + 15x + x^2 = 88

x^2 + 15x - 34 = 0

(x + 17)(x - 2) = 0
using zero product property:-
x + 17 = 0 or x - 2 = 0 giving:-

x = -17 , x = 2

x is the amount that the length and width are increased by.

x = -17 is negative and doesn't make sense in this context and can be ignored; so the amount of increase is 2 feet.

lakkis [162]

Given:

The ratio of the area between a small square of land and a large square

of land is 3: 7.

Total area of the two squares of land (in sq. meter) is 4000.

Required:

The area of each square of land.

Answer:

We have the ratio of the area between a small square of land and a large square of land is 3: 7.

Let

$x^$

be the area of the square of land.

Then their ratio is given by,

$3x^:7x^$

Also given that the total area of the two squares of land (in sq.meter) is

4,000.

The area of

Therefore,

$\begin{gathered} 3x^+7x^=4000 \\ \Rightarrow10x^=4000 \\ \Rightarrow x^=400 \\ \end{gathered}$

Therefore,the area of small square (in sq. meter) is,

$3x=3(400)=1200$

and the area of large square (in sq. meter) is,

$7x=7(400)=2800$

Final Answer:

The area of small and large square respectively (in sq. meter) is,1200 and 2800.
