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.

Therefore, the actual length is 9.5 ft.

Answer: 125.7 degrees

Step-by-step explanation:

supplementary angles add up to 180 degrees.

angle 1 + angle 2 = 180

54.3+angle 2=180.0

54.3-54.3+angle 2=180.0-54.3

angle 2=180.0-54.3

angle 2=125.7 degrees

The given series is an arithmetic series and its sum is 36.4

The summation or sigma notation is used to express long summation into a single formula.

The series, given in a summation notation, is:

     [tex]\sum\limits^{10}_{n=4} {(0.8n-0.4)}[/tex]

The formula inside the sum notation represent the nth term, a(n).

Let evaluate the terms for some n, starts from n = 4 as indicated by the lower limit of the summation notation:

a(4) = 0.8 (4) - 0.4 = 2.8

a(5) = 0.8 (5) - 0.4 = 3.6

a(6) = 0.8 (6) - 0.4 = 4.4

This form a new arithmetic series, with the first term, let say f(1) =2.8 and common difference, d = 0.8.

The number of terms in this new geometric series is given by the upper and lower limit of the summation notation:

number of terms = 10 - 4 + 1 = 7

Use the sum formula for an arithmetic series,

S(n) = n/2 [2.f(1) + (n - 1) . d]

Substitute n = 7, f(1) = 2.8, and d = 0.8 into the formula:

S(7) = 7/2 [2. (2.8) + (7 - 1) . (0.8)]

S(7) = 36.4

Answer: width = 12 inches

length =  28 inches

Step-by-step explanation:

l = 4 + 2w

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)

= 4 + 24

= 28 inches

checking

Perimeter = 2 ( 28 + 12 )

= 2 (40)

= 80 inches

Step-by-step explanation:

a number is only divisible by 4, if the number formed by the last 2 digits is divisible by 4.

The expression that represents the perimeter of the triangle in centimeters is; 73[tex]w^{2}[/tex]  +  128wx  +  128[tex]x^{2}[/tex]  +  60wy +  116[tex]y^{2}[/tex]  +  64xy

We are given the measurement of each side length of the triangle, i.e.

(8w +8x) (8w+8x)

(3w + 10y) (3w+10y)

(4y + 8x) (4y+8x)

After simplifying the measurement on each side, we get;

(8w +8x) (8w+8x)= 64[tex]w^{2}[/tex] + 128wx + 64[tex]x^{2}[/tex]

(3w + 10y) (3w+10y)= 9[tex]w^{2}[/tex] +60wy +100[tex]y^{2}[/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

The compound inequality that describes Tammy's test score x 85 < x < 92 and Tammy's test score is between 85 and 92

The given parameters are

Sam's test score is between 100 and 107

This means that

100 < Sam's score < 107

From the question, we have:

Tammy scored about 15 fewer points.

This means that

Tammy = Sam - 15

So, we have

Sam = Tammy + 15

Where

Tammy = x

This gives

Sam = x + 15

So, we have

100 < x + 15 < 107

Subtract 15 from the sides of the inequality

So, we have

85 < x < 92

This means that the compound inequality that describes Tammy's test score x 85 < x < 92

The equation of the line is y = -3x/5 + 1 that passes through (5, −2), and is perpendicular to y = (5/3)x - 3.

A straight line is a combination of endless points joined on both sides of the point.

The slope 'm' of any straight line is given by:

[tex]\rm m =\dfrac{y_2-y_1}{x_2-x_1}[/tex]

It is given that:

The line passes through (5, −2) and is perpendicular to y = (5/3)x - 3

The slope of the line y = (5/3)x - 3

m = 5/3

The slope of the line perpendicular to the above line:

M = -3/5

The ratio that y increase as x increases is the slope of a line. The slope of a line reflects how steep it is, but how much y increases as x increases. Anywhere on the line, the slope stays unchanged (the same).

The equation of the line

y + 2 = (-3/5)[x - 5]

y = -3x/5 + 1

Thus, the equation of the line is y = -3x/5 + 1 that passes through (5, −2), and is perpendicular to y = (5/3)x - 3.

[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]

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,

Answer:181/2

Step-by-step explanation:

90.5 as a fraction is 181/2

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

[tex]y=kx+b\\k=the\ slope=-0.5\\(0,-8) \ hence,\\-8=-0,5*0+b\\-8=0+b\\-8=b\\Thus,\\y=-0.5x-8[/tex]

The equation of line is:

y = (5/2) x - 11

Given,

Points (x₁, y₁) = (-12, -6) and (x₂, y₂) = (8, 9)

We can find the slope using the equation for slope

m = (y₂ - y₁) / (x₂ - x₁)

   = (9 -(-6)) / (8-(-12))

   = (9+6) / (8 + 12)

    = 15/20 = 3/4

We know the slope and a point, so we can use point slope form to make an equation

y-y₁ = m(x-x₁)

y - (-6) = 3/4 (x-(-12))

Distribute

y+6 = 3/4x – 3/4 × 2

y+6 = 3/4x - 3/2

Add -6 to each side

y + 6 -6 = 3/4x - (3/2)-6

y = 3/4x - (-9/2)

y = 3/4x + 9/2
