Two rectangles have the same area of 24cm².The second rectangle is 4cm shorter and 1cm wider than the first.What is the length a

lukranit [14]

Answer:

First rectangle: 12 cm by 2 cm

Second rectangle: 8 cm by 3 cm

Step-by-step explanation:

You can examine factor pairs of 24 to see which pairs meet the requirements:

24 = 1×24 = 2×12 = 3×8 = 4×6

Factor pairs (2, 12) and (3, 8) have one factor that differs by 1 and another factor that differs by 4. We can use these numbers to describe the rectangles:

First rectangle: 12 cm by 2 cm

Second rectangle: 8 cm by 3 cm

Help that one side is 2x-2

bogdanovich [222]

Answer: x = 2/3

Step-by-step explanation:

Add all sides.

2x-2 + 2x - 2 + x + x =

6x - 4

Put " = 0 "

6x-4 = 0

Add 4 to both sides.

6x-4 = 0

+4 = +4

-------------------

6x=4

You get 6x = 4 because the 4 on the left side of the equals sign cancelled out!

NOW DIVIDE 6 FROM BOTH SIDES

6x = 4

/6 /6

-----------

x= 4/6

SIMPLIFY / REDUCE FRACTION

4/6 divided by 2 = 2/3

2/3 is the answer !

Among 320 randomly selected airline travelers, the mean number of hours spent travelling per year is 24 hours and the standard d

Ostrovityanka [42]

The margin of error of the random selection is 0.29

The given parameters are:

$n = 320$ --- the sample size

$\sigma = 2.9$ --- the standard deviation

$\bar x = 24$ --- the mean

$\alpha = 90\%$ --- the confidence level.

The margin of error (E) is calculated as follows:

$E = z \times \sqrt{\frac{\sigma^2}{n}}$

So, we have:

$E = z \times \sqrt{\frac{3.2^2}{320}}$

$E = z \times \sqrt{\frac{10.24}{320}}$

The z-value for 90% confidence level is 1.645.

Substitute 1.645 for z

$E = 1.645 \times \sqrt{\frac{10.24}{320}}$

$E = 1.645 \times \sqrt{0.032}$

Take square roots

$E = 1.645 \times 0.1789$

Multiply

$E = 0.2943$

Approximate

$E = 0.29$

Hence, the margin of error is 0.29
