Answer:

[tex] - 8 \times |2 = - 16| [/tex]

Answer:

x = 5

Step-by-step explanation:

3(x + 7) + 4 = 40 ( subtract 4 from both sides )

3(x + 7) = 36 ( divide both sides by 3 )

x + 7 = 12 ( subtract 7 from both sides )

x = 5

As a check

substitute x = 5 into the left side of the equation and if the value obtained is equal to the right side (40) then it is a solution

3(5 + 7) + 4

= 3(12) + 4

= 36 + 4

= 40

left side = right side

then x = 5 is the solution to the equation

A good way to find patterns in data is to arrange it in tabular form, which acts as an "input-output" machine.

A pattern in mathematics is a recurring arrangement of numbers, forms, colors, and other elements. Any kind of event or object can be connected to the Pattern.

A pattern is referred to as a rule or a way in which a group of numbers is related to one another. Sometimes a pattern is also referred to as a sequence.

Putting data into a tabular format, which functions as an "input-output" computer, is a useful way to find patterns. It will process an input value, return an output value, and take another value as an input.

The table's process column will make it easier to comprehend how input and output are related.

The equation in slope-intercept form y = 4/3 x + 4/3 contains the points (-1 , 0) and (2 , 4).

An equation of a line in slope-intercept form is given by the formula y = mx+ b, where m is the slope of the line and b is the y- intercept.

If you know two points on a line, you can use them to write the equation of the line in slope-intercept form.

First is to find the slope of the line using the two given points.

let Point 1(-1 , 0) and Point 2(2 , 4)

slope = m = (y2 - y1) / (x2 -x1)

m = (4 - 0) / (2 - -1)

m = 4/3

Next, use the slope and one of the points to find the value of the y-intercept, b. Plug in these values in the formula for slope-intercept form.

y = mx+ b

y = 4/3 x + b

Using Point 1,

0 = 4/3 (-1) + b

0 = -4/3 + b

b = 4/3

Finally, set up the equation of the line in slope-intercept form.

y = mx+ b

where m = 4/3 and b = 4/3

y = 4/3 x + 4/3

Triangle is a very common figure to deal with our daily life for example in our daily life to measure the height of any tower then there is a huge application of the right angle triangle.

A scalene triangle is a triangle whose all sides are unequal.

Since congruent sides are the sides that are equal in length but in a scalene triangle, none of the sides are equal to each other.

The actual length, if the length of the model is 10 ft and the scale factor is greater than one is Option(b) 9.5 ft.

The basic formula to find the scale factor of a figure is as:

Scale factor = Dimensions of the new shape ÷ Dimensions of the original shape.

Given:

length of the model = 10 ft

Now we determine which actual length has a scale factor greater than one.

(a) Scale factor = (10/10)

Here, we can see that the scale factor is equal to 1.

(b) Scale factor = (10/9.5) = 1.05

Here, we can see that the scale factor is greater than 1.

(c) Scale factor = (10/12) = 0.83 ( 1 yard = 3 foot)

Here, we can see that the scale factor is less than 1.

[tex]\textsf{b)} \quad \boxed{\begin{minipage}{8.5 cm}\sf The angle between the tangent and the radius at a point \\on a circle is $90^{\circ}$.\end{minipage}}[/tex]

Step-by-step explanation:

The triangle inside the circle is an isosceles triangle, since two of its sides are the radius of the the circle (and therefore equal in length).

Therefore, its two base angles are 27°.

A tangent is a straight line that touches a circle at only one point.

The tangent of a circle is always perpendicular to the radius.

[tex]\implies x + 27^{\circ} = 90^{\circ}[/tex]

[tex]\implies x +27^{\circ}-27^{\circ}= 90^{\circ} - 27^{\circ}[/tex]

Answer: width = 12 inches

length =  28 inches

Step-by-step explanation:

Perimeter = 2 ( l + w  )

80 = 2 ( 4 + 2w + w )

80 = 2 ( 4 + 3w )

80 = 8 + 6w

80 - 8 = 6w

72 = 6w

w = 72 / 6

width = 12 inches

length = 4 + 2 (12)

The maximum distance up the wall the ladder will reach = 19.4 ft

The total length of the ladder, L = 20 ft

Minimum distance of the base of the ladder to the wall, B = 1/4 x 20 = 5 ft

Now we need to find the maximum distance up the wall the ladder will reach. This is obtained when the base distance is the least.

i.e., when the base = 5 ft.

Now the ladder, the wall and the base distance between wall and ladder constitute a right triangle. In this right triangle, the ladder is the hypotenuse and the height of the wall up to which ladder reach, 'x' is its altitude with base = 5ft.

Then using Pythagoras theorem,

    [tex]L^2 = B^2 +x^2[/tex]

⇒ [tex]x^2 = L^2 - B^2 = 20^2 - 5 ^2[/tex]
