a. This is the geometric sequence: a1 = 1.5 m = 150 cm, r = 0.74

The formula now is an = a1 x r ^ n-1

Just substitute a1 = 150 cm and r = 0.74

an = 150 x (0.74) ^ n – 1

b. The second part is:

A6 = 150 x 0.74 ^ 6-1

= 150 x 0.74 ^5

= 150 x 0.221906624

= 33.28509936 cm

a right triangle has a height of 20 centimeters and a base of 10 centimeters.what is the area of the triangle?

viktelen [127]

Answer:

The area of the right triangle is 100 centimeters squared.

Step-by-step explanation:

The formula for the area of a right triangle is:

$Area = \frac{a*b}{2}$

Area = (a*b) / 2

The height of a triangle is represented by a. The base is represented by b.

Knowing this, we can use what they give us for the values, by plugging them into the formula.

a is 20 cenimeters

b is 10 centimeters

Therefore :

$Area = \frac{200}{2}$

$Area = 100$

So, the area of the right triangle is 100 centimeters squared.

Two cubes are tossed. Find P(only one shows a 2).

djverab [1.8K]

The probability that only one shows a 2.

There are 36 different outputs (6x6) = 36

There are 6 combinations where the first cube shows a 2, these are 2,1;2,2;2,3;2,4;2,5; and 2.6

There are 6 combinations where the second cube shows a 2: 1,2;2,2;3,2;4,2;5,2; and 6,2.

Of those one combination on each set shows two 2.

Then the number of combinations with only one 2 are 6 - 1 + 6 -1 = 10

Now the probabilit is 10 out of 36 = 10 / 36 = 5 / 18
