Let x be the smaller than 4 ×[tex]10^{-2}[/tex].

To find, the number of times smaller is 2 × [tex]10^{-3}[/tex] than 4 × [tex]10^{-2}[/tex] = ?

∴ x = [tex]\dfrac{4\times 10^{-2}}{2\times 10^{-3}}[/tex]

The following D Tether ball pole shadow: 0.6\,\text{m}0.6m0, point, 6, start text, m, end text Flagpole shadow: 1.36\,\text{m}1.36m1, point, 36, start text, m, end text and E Tether ball pole shadow: 2\,\text{m}2m2, start text, m, end text Flagpole shadow: 4.8\,\text{m}4.8m could be the lengths of the shadows. Correct Option is 4 and 5.

Let's assume "x" is the length of the tether ball pole shadow, and "y" is the length of the flagpole shadow.

According to the information given, the proportional relationship can be expressed as:

Tether ball pole height / Tether ball pole shadow length = Flagpole height / Flagpole shadow length

The height of the tether ball pole is 333 meters, and the height of the flagpole is 6.8 meters.

So, we have the following equation:

333 meters / x = 6.8 meters / y

Now, let's solve for "y" in each choice and check which choices satisfy the proportional relationship:

Choice A:

333 / 1.35 = 6.8 / 3.4

246.67 ≈ 2

Choice B:

333 / 1.8 = 6.8 / 4.08

185 ≈ 1.67

Choice C:

333 / 3.75 = 6.8 / 8.35

88.8 ≈ 0.81

Choice D:

333 / 0.6 = 6.8 / 1.36

555 ≈ 5

Choice E:

333 / 2 = 6.8 / 4.8

166.5 ≈ 1.42

The two choices that satisfy the proportional relationship are:

(Choice D) Tether ball pole shadow: 0.6 m, Flagpole shadow: 1.36 m

(Choice E) Tether ball pole shadow: 2 m, Flagpole shadow: 4.8 m

Answer:

  15°

Step-by-step explanation:

The exterior angle at vertex S is 360°/12 = 30°. That angle has a measure that is equal to the sum of the congruent angles at R and T of ΔRST. In other words, ...

  ∠T = 30°/2 = 15°

The size of angle STR is 15°.

The sides of a regular polygon are congruent.

The size of STR is 15 degrees

The polygon is 12-sided.

This means that:

[tex]\mathbf{n =12}[/tex]

The sum of angles in a regular hexagon is 360.

So, the angle at vertex S is:

[tex]\mathbf{\theta = \frac{360}{n}}[/tex]

This gives

[tex]\mathbf{\theta = \frac{360}{12}}[/tex]

[tex]\mathbf{\theta = 30^o}[/tex]

The external angle of a triangle equals the sum of the opposite internal angles.

This means that:

[tex]\mathbf{\theta = \angle STR + \angle SRT}[/tex]

Where:

[tex]\mathbf{ \angle STR = \angle SRT}[/tex]

So, we have:

[tex]\mathbf{\theta = \angle STR + \angle STR}[/tex]

[tex]\mathbf{\theta = 2\angle STR}[/tex]

Substitute [tex]\mathbf{\theta = 30^o}[/tex]

[tex]\mathbf{30^o = 2\angle STR}[/tex]

Divide both sides by 2

[tex]\mathbf{15^o = \angle STR}[/tex]

Rewrite as:

[tex]\mathbf{\angle STR = 15^o }[/tex]

Hence, the size of STR is 15 degrees

Answer:

The greatest possible value for b is 26.

Step-by-step explanation:

Given that the line passes through the Origin O(0, 0); A(-2, b - 14) &

B(14 - b, 72).

Let us assume the points are in the order: AOB.

Since the line passes through all these points the slope of the line segment AO = The slope of the line segment AB.

Slope of a line with two points: [tex]$ \frac{y_2 - y_1}{x_2 - x_1} $[/tex]   where [tex]$ (x_1, y_1) $[/tex] and [tex]$ (x_2, y_2) $[/tex] are the points given.

[tex]$ (x_1, y_1) = (0,0) $[/tex]

[tex]$ (x_2, y_2) = (-2, b - 14) $[/tex]

Therefore, the slope of the line segment AO = [tex]$ \frac{b - 14}{-2} $[/tex]

Similarly, for the slope of the line segment OB.

The two points are [tex]$ (x_1, y_1) = (0, 0) $[/tex] and [tex]$ (x_2, y_2) = (14 - b, 72) $[/tex].

The slope is:  [tex]$ \frac{72}{14 - b } $[/tex]

Since, the slopes are equal we can equate:

[tex]$ \frac{b - 14}{-2} = \frac{72}{14 - b} $[/tex]

[tex]$ \implies \frac{b - 14}{-2} = \frac{72}{-(b - 14)} $[/tex]

[tex]$ \implies (b - 14)^2 = 72 \times 2 = 144 $[/tex]

[tex]$ \implies (b - 14)^2 = 12^2 $[/tex]

Taking square root on both sides we get:

[tex]$ \implies (b - 14) = \pm 12 $[/tex]

[tex]$ \implies b = 2 \hspace{2mm} or \hspace{2mm} 26 $[/tex]

Therefore, the maximum value of b = 26.

Hence, the answer.

Step-by-step explanation:

Answer:

1 - 32.5

Step-by-step explanation:

If the perimider is less then 172, that the limit is 171. 171 - (53)2 = 65. divide that by the two sides that are the width it equals 32.5

Perimeter is the sum of the length of the sides used to make the given figure. The range of the width of the rectangle is (0,33).

Inequalities help us to compare two unequal expressions. Also, it helps us to compare the non-equal expressions so that an equation can be formed. It is mostly denoted by the symbol <, >, ≤, and ≥.

Given that the perimeter of a rectangle must be less than 172 feet. Also, given that the length of the rectangle is 53 feet. Therefore, we can write inequality of the width of the rectangle as,

2(Length) + 2(Width) < Perimeter

2(53 feet) + 2(Width) < 172 feet

106 feet + 2(Width) < 172 feet

2(Width) < 172 feet - 106 feet

2(Width) < 66 feet

Width < 66feet / 2

Width < 33 feet

Hence, the range of the width of the rectangle is (0,33).

Question:

A width of a rectangular painting is 3 in. More than twice the height. A frame that is 2.5 in. Wide goes around the painting

a. write an expression for the combined area of the painting and frame.

b. use the expression to find the combined area when the height of the painting is 12 in.

c. use the expression to find the combined area when the height of the the painting is 15 in.

Answer:

a) (h + 5)(2h + 8) is the expression for the combined area of the painting and frame

b) The combined area when h = 12 is 544 square inches

c) The combined area when h = 15 is 760 square inches

Solution:

Given that,

A frame that is 2.5 inches wide goes around the painting

The frame will go around all 4 sides of the painting.

That means that the length of each side of the painting will increase by 2.5 inches

Therefore,

The height of painting and frame is:

h = h + 2.5 + 2.5

h = h + 5

(2.5  inches on the top and the bottom)

Also given that,

Width of a rectangular painting is 3 inches more than twice the height

w = 3 + 2h

Now the width of painting and frame is:

w = 3 + 2h + 2.5 + 2.5

(Again, 2.5 inches on the top and the bottom)

w = 2h + 8

Thus the combined area of the painting and frame is:

[tex]Combined\ area = (h+5)(2h+8)[/tex]

B) Substitute h = 12 inches

[tex]Combined\ area = (12+5)(2(12)+8)\\\\Combined\ area = 17 \times (24+8) = 17 \times 32\\\\Combined\ area = 544[/tex]

Thus the combined area when h = 12 is 544 square inches

C) Substitute h = 15 inches

[tex]Combined\ area = (15+5)(2(15)+8)\\\\Combined\ area = 20 \times (30+8) = 20 \times 38\\\\Combined\ area = 760[/tex]

Thus combined area when h = 15 is 760 square inches

Answer: x = 15

Step-by-step explanation: The first thing to note is that what we have here are two similar triangles. First we have triangle ABC and secondly we have triangle EDC. Line BD is a transversal that cuts line AE at point C. Hence we can deduce that angle ACB is equal in measurement to angle ECD (opposite angles). Next we also observe that the other two angles are right angles, that is, 90° in size. Therefore we can conclude that the other two angles (angle ABC and angle EDC) are also of the same measurement.

We can now establish the ratio of the similar sides.

Line AB = Line ED

Line AC = Line EC

AB/ED = AC/EC

24/40 = 2x/3x + 5

3/5 = 2x/3x + 5 {the left hand side has been reduced to it's simplest form}

Next we cross multiply and that gives us

3(3x + 5) = 5(2x)

9x + 15 = 10x

Subtract 9x from both sides of the equation

15 = 10x - 9x

15 = x

Step-by-step explanation:

Givena general quadratic equation

ax²+bx+c = 0

The general formula for finding x is;

x = -b±√b²-4ac/2a

Where a,b and c are the coefficient of x², x and x° respectively

Given the solution in question to be;

x = 5±2√7/3

The quadratic equation that has thw above general solution will be;

3x²-10x+6 = 0

From the equation, a = 3, b= -10 and c = 6

Substituting this value in the general formula to get x we have;

x = -(-10)±√(-10)²-4(3)(6)/2(3)

x = 10±√100-72/6

x = 10±√28/6

x = 10±√7×4/6

x = 10±2√7/6

Dividing through by 2 gave;

x = 2(5±2√7)/6

x = 5±2√7/3 (which gives the solution in question)
