Answer:

3.84 inches squared

Step-by-step explanation:

The area of a triangle is given by the formula:

Area = 1/2 * base * height

In this problem, our side lengths are:

Base = 2.4 inches

Height = 3.2 inches

So, our area can be found:

Area = 1/2 * 2.4 * 3.2 = 3.84 inches squared

Find the value of x. A.4 B.5 C.6 D.9

ra1l [238]

The equation should be...

a^2 + b^2 = c^2

x^2 + (x+3)^2 =10.81665383^2

When you plug it in...

6^2 + (6+3)^2 = 117

6^2 + (9)^2 = 117

36 + 81= 117

Write an equation for the nth term of the arithmetic sequence. Then find a 30

AnnZ [28]

Answer:

The nth term is given by: $a_n = -9 + 3(n-1)$

The 30th term is 78.

Step-by-step explanation:

Arithmetic sequence:

The nth term of an arithmetic sequence is given by:

$a_n = a_1 + (n-1)d$

In which $a_1$ is the first term and d is the common difference between terms.

-9, -6, - 3,0

This means that $a_1 = -9, r = -6 - (-9) = -6 + 9 = 3$ . So

$a_n = -9 + 3(n-1)$

30th term:

$a_30 = -9 + 3(30-1) = -9 + 87 = 78$

The 30th term is 78.

What is the length of the unknown leg in the right triangle? A right triangle has a side with length 20 meters, hypotenuse with

galben [10]

The length of the unknown leg of the triangle is 15 m.

Step-by-step explanation:

Length of one leg = 20 m

Length of the hypotenuse= 25m

As it is a right angled triangle we can use pythogoras theorem.

Let the unknown length be y

(20) (20) + y(y) = (25) (25)

400 + y(y) = 625

y(y) = 225

y = √225

y = 15

The length of the unknown leg is 15 m.
