Mathematics

Rudik [331]2 years ago

Answer:

Step-by-step explanation:

Remark

Here are the formulas for what you are asking for.

P = s1 + s2 + s3

Area = height * base / 2

Givens

s1 = 12.6

s2 = 6.3

s3 = 7.4

height = 4.5

base = 7.4

The area is just slightly different than it normally is. The reason is the height. It is not directly connected to the base. The construction is called the base extended.  See the givens for what that is.

Solution

<em>Perimeter</em>

P = s1 + s2 + s3                        Substitute givens into the formula

P = 12.6+6.3 + 7.4

p = 26.3

<em>Area</em>

Area = (B * H)/ 2

Area = 7.4 *4.5 / 2

Area = 16.65

Answer:

Area: 16.65m^2 (^2 means to the power of 2 exponent, or squared)

Perimeter: 26.3 m

Step-by-step explanation:

Triangle Area formula: bh/2

Plug it in: (7.4)(4.5)/2=16.65

Perimeter: Add the sides

12.6+7.4+6.3=26.3

Can someone help me for question 18 pls? I really need help to solve this question!!
earnstyle [38]

Plug the x-values from the table into the given equation and solve for y.

y = 5 - x²

<u>First column</u>

replace x with -2

y = 5 - (-2)²

  = 5 - (4)

  = 1

(x, y) = (-2, 1)

<u>Second column</u>

replace x with -1

y = 5 - (-1)²

  = 5 - (1)

  = 4

(x, y) = (-1, 4)

<u>Third column</u>

replace x with 0

y = 5 - (0)²

  = 5 - (0)

  = 5

(x, y) = (0, 5)

<u>Fourth column</u>

replace x with 1

y = 5 - (1)²

  = 5 - (1)

  = 4

(x, y) = (1, 4)

<u>Fifth column</u>

replace x with 2

y = 5 - (2)²

  = 5 - (4)

  = 1

(x, y) = (2, 1)

The perimeter of a rectangle is 96 inches. The length of the rectangle is three times its width. Find the dimensions of the rect
Oksanka [162]

Hey there!!

Perimeter of a rectangle =2 ( length + width )

Let's take the measure of the width as ' x '

Then, the length would be ' 3x '

Hence,

... 2 ( x + 3x ) = 96

... 2 ( 4x ) = 96

... 8x = 96

... x = 96 / 8

... x = 12

Width = 12 inches

And, length would be 36 inches.

Hope my answer helps!!

Find the common ratio of the geometric sequence 4,3,9over4
uranmaximum [27]

Answer:

0.75

Step-by-step explanation:

Given a geometric sequence: a_1,a_2,a_3...,a_n

The common ratio is derived by dividing any next term by the preceeding term.

That is:

r=\dfrac{a_2}{a_1} =\dfrac{a_3}{a_2}=\cdots =\dfrac{a_n}{a_{n-1}}

In the geometric sequence: 4,3,9/4

Common ratio, r=\dfrac{3}{4} =\dfrac{9/4}{3}=0.75

The common ratio of the given geometric sequence is 0.75.
