The area of the floor the carpet needs to cover is 20 1/8 cm².

The floor has the shape of a rectangle. A rectangle is a 2-dimensional quadrilateral with four right angles.

Area of a rectangle = length x width

5 3/4 x 3 1/2

23/4 x 7/2 = 161/8 = 20 1/8 cm²

Answer:

12

Step-by-step explanation:

For this question, simply plug in -2 for x:

Answer:

192 SQUARE FEET

Step-by-step explanation:

Area of a triangle= 1/2 ×base×height

1/2 of the base =32/2 ft

=16 ft

Let the height be A ft and another side(16 ft) be B ft

We know that, A^2 + B^2 =Hypotenuse^2

OR, A^2 + 16^2 = 20^2

OR, A^2= 400-256

OR, A^2 =144

OR, A= Square root of 144

OR, A=12 ft

By the problem,

1/2 ×Base×Height =Area of half of the triangle

1/2 ×16×12= Area of half of the triangle

96=Area of half of the triangle

AREA OF THE TRIANGLE=96 ×2

AREA OF THE TRIANGLE=192 SQUARE FEET.

Answer:

Angles H, J, M, N

Step-by-step explanation:

Since m<p is 90 degrees it must be the largest angle so both triangles have angle 45-45-90. m<P is equal to m<K. This means that angle h, j, m, and n are equal.

angles M, N, and J.

try drawing diagrams to help you figure out the problem :)

A little square marked on angle means that the angle is 90 degrees.

By the vertical angle theorem, angles opposite each other are equal thus the angle opposite the angle with the little square is also 90 degrees.

That angle is split into two angles that is off measure 22 degrees and x degrees

  -- x + 22 = 90 --> x = 68.

Hope that helps!

Answer:

68

Step-by-step explanation:

[tex] \hookrightarrow \: x + 22 = 90(complementary \: angles) \\ [/tex]

[tex] \hookrightarrow \: x + 22 = 90 \\ \hookrightarrow \: x = 90 - 22 \\ \hookrightarrow \: x = 68[/tex]

Answer:

Option C. between 6 and 18 hours per week

Step-by-step explanation:

We are given that distribution of times is symmetric and mound shaped and this implies that data is normally distributed.

We also know that in the normal distribution the 95% of data lies within 2 standard deviations i.e. mean± 2*standard deviation.

So, 95% of the television viewing times falls in interval

mean± 2*standard deviation

12±2*3

12±6

[6,18]

Thus, [6,18] is an interval where you believe approximately 95% of the television viewing times fell in the distribution.

Given :

⠀

To Find :

⠀

Solution :

We know that,

[tex]\qquad{ \bold{ \pmb{2(Length + Breadth ) = Perimeter_{(rectangle)}}}}[/tex]

Let's assume the width of the rectangle as x inches. Then the length will become (3x + 9).

⠀

Now, Substituting the given values in the formula :

[tex]\qquad \dashrightarrow{ \sf{2(3x + 9 + x )= 138}}[/tex]

[tex]\qquad \dashrightarrow{ \sf{2(4x + 9 )= 138}}[/tex]

[tex]\qquad \dashrightarrow{ \sf{8x + 18= 138}}[/tex]

[tex]\qquad \dashrightarrow{ \sf{8x = 138 - 18}}[/tex]

[tex]\qquad \dashrightarrow{ \sf{8x = 120}}[/tex]

[tex]\qquad \dashrightarrow{ \sf{x = \dfrac{120}{8} }}[/tex]

[tex]\qquad \dashrightarrow{ \bf \: x = 15}[/tex]

⠀

Therefore,

[tex]\qquad { \pmb{ \bf{ Width _{(frame)} = x = 15 \: inches}}}\:[/tex]

[tex]\qquad { \pmb{ \bf{ Length _{(frame)} = (3x + 9) \: = 3(15) + 9 = 54 \: inches}}}\:[/tex]

The solution for the linear inequality, in interval notation, is [tex]\:(-\infty \:,\:-\frac{7}{6}][/tex].

It is an expression mathematical that represents a non-equal relationship between a number or another algebraic expression. Therefore, it is common the use of follow symbols: ≤ (less than or equal to), ≥ (greater than or equal to), < (less than) and > (greater than).

The solutions for inequalities can be given by: graph in a number line or numbers.

For solving this exercise, it is necessary to find a number solution for  the given inequality.

                                 12x-8≤6x-15

Answer:A

Step-by-step explanation:

Answer:

C. 128 in²

Step-by-step explanation:

We know that the opposite sides of rectangles are congruent, so 8 = 2x. If we divide 8 by 2 and 2x by 2, we get x = 4.

Now, the area of a rectangle is l × w, where l = length and w = width. The dimensions of this rectangle are 8 and 16, so 8 × 16 = 128 in².

The answer is 72

Step-by-step explanation:

The formula to find the area of a trapezoid

[tex]A= \frac{1}{2}h(b_{1} + b_2{} )[/tex]

First, we can add the bottom base together

5 + 8 + 3 = [tex]16_{2}[/tex]

We know that the height of the trapezoid is 6 and base1 is 8

[tex]A= \frac{1}{2}6(16 + 8)[/tex]

[tex]A=\frac{1}{2}6(24)[/tex]

[tex]A=3(24)[/tex]

[tex]A=72[/tex]

OR

Find the area of the two triangles

[tex]A=\frac{1}{2}5(6)\\\\A=5(3)\\\\A=15\\\\[/tex][tex]A=\frac{1}{2}3(6)\\\\A=3(3)\\\\A=9\\[/tex]

15 + 9 = 24

For the area of the rectangle

6 x 8 = 48

48 + 24 = 72
