Answer:

The height of the pole is 167 m

Step-by-step explanation:

The given parameters are;

Increase  in the length of the shadow = 90 m

Initial angle of elevation of the Sun = 58°

Final angle of elevation of the Sun = 36°

We have a triangle formed by the change in the length of the shadow and the rays from the two angle of elevation to the top of the pole giving an angle 22° opposite to the increase  in the length of the shadow  

We have by sin rule;

90/(sin (22°)  = (Initial ray from the top of the pole to the end of the shadow's length)/(sin(122°)

Let the initial ray from the top of the pole to the end of the shadow's length = l₁

90/(sin (22°)  = l₁/(sin(122°)

l₁ = 90/(sin (22°) ×(sin(122°) = 283.3 m

Therefore;

The height of the pole = 283.3 m × sin(36°) = 166.52 m

The height of the pole= 167 m to three significant figures.

Answer:

height of pole = 121 m (to 3 significant figures

Step-by-step explanation:

From the diagram attached to this solution:

Let the length of the shadow = b

Let the height of the triangle = h

[tex]Triangle\ 1\\\\Tan\ (58)\ =\ \frac{h}{b}\\1.60\ =\ \frac{h}{b} - - - - - -(1)\\\\[/tex]

[tex]Tan\ (36) = \frac{h}{b+90} \\0.73\ =\ \frac{h}{b+90} - - - - (2)[/tex]

[tex]From\ equation\ (1)\\1.60 = \frac{h}{b}\\ cross-multiplying\\1.60b = h - - - - - (3)\\\\\\from\ equation\ (2)\\0.73\ =\ \frac{h}{b+90}\\ corss-multiplying\\0.73b\ +\ 65.7 = h\\h\ =\ 0.73b\ +\ 65.7- - - - - -(4)\\[/tex]

Notice that equation (3) = equation (4) = h

[tex]1.60b = 0.73b\ + 65.7\\1.60b\ -\ 0.73b\ = 65.7\\0.87b\ =\ 65.7\\b\ =\ \frac{65.7}{0.87} = 75.52\ m\\[/tex]

Now let us find the height of pole from equation (3)

1.60b = h - - - - - - (3)

where b = 75.52

h = 1.60 × 75.52

h = 120.83 m

= 121 m (to three significant figure

Answer:

1/2, 3/6 and 2/4 are equivalent fractions.

Step-by-step explanation:

To know if the fractions are equivalent, their simplest form should be the same.

So we must simplify all the fractions to their simplest form.

To find the simplest form of a fraction, we must divide the numerator and denominator with their GCF (Greatest Common Factor)

So:

1/2 = 1/2

1/3 = 1/3

3/4 = 3/4

3/6 = 1/2 ( The GCF for 3 and 6 is 3)

2/4 = 1/2 ( The GCF for 2 and 4 is 2)

4/10 = 2/5 ( The GCF for 4 and 10 is 2)

Because 1/2, 3/6 and 2/4 has the same simplest form, they are equivalent fractions.

Answer:

The correct options are;

A. 1·2 = 2

B. 1·1 = 1

E. 1 + 1 = 2

Step-by-step explanation:

Given that the equations 1.2 = 2 and 1.1 = 1 are correctly written as 1·2 = 2 and 1·1 = 2, we have;

The product of any number and one is equal the same number, that is a × 1 = a

Whereby we have the expression 1·2 which is 1 × 2,  we therefore have;

1 × 2 = 1 · 2= 2

B. Similarly we have;

1 · 1 = 1 × 1 = 1

Also, 1 + 1 = 2 is correct as the sum of two numbers is equal to the sum of the count of the numbers, therefore;

E. 1 + 1 = 2 is correct.

Answer:

(D) [tex]x>-10[/tex]

Step-by-step explanation:

If we have the inequality [tex]-7x + 4 > -8x - 6[/tex], we can simplify it down and get [tex]x[/tex] isolated on one side of the equation.

Add 6 to both sides:

[tex]-7x + 4 + 6 > -8x - 6 + 6\\\\-7x + 10 > -8x[/tex]

Add [tex]8x[/tex] to both sides of the inequality:

[tex]-7x + 10 + 8x > -8x+8x\\\\x + 10 > 0[/tex]

Subtract 10 from both sides of the inequality:

[tex]x + 10 - 10 > 0 - 10\\\\x > -10[/tex]

So (D) [tex]x>-10[/tex] is the correct simplification.

Hope this helped!

The value of the angle x will be 40°. Then the correct option is B.

The circle is at equidistant of points drawn from the center. The radius of a circle is the distance between the center and the circumference.

The minor arc  is 75°. And the another arc is 130°.

We know that the complete circle subtends 360 degrees.

Then the measure of the major arc will be

Major arc + 130° + 75° = 360°

       Major arc + 205° = 360°

                   Major arc = 155°

Then the value of the angle x will be given by the half of the difference of the major arc to minor arc.

x = (Major arc – minor arc) / 2

x = (155 – 75)/2

x = 80 / 2

x = 40°

Thus, the value of the angle x will be 40°.

Then the correct option is B.

[tex]4n-n^2[/tex]

Step-by-step explanation:

I use 'n' as the unknown value, but you can use any letter you want as the variable.

The product of four and a number would be represented by '4 * n'. The ideal way to write this would be '4n', even though '4 * n' is also correct in value.

The square of the number would be n². Squaring a number is multiplying a number by itself.

The phrase 'difference between...' means subtraction.

Putting it together:

"The difference between the product of 4 and a number and the square of the number" would be:

2000

Step-by-step explanation:

Salim will need to get 2000 clicks in order to get $50 per month or more.

First: 5 cents goes into one dollar 20 times.

Second: You multiply 20 times 50. This is how you get 2000. There is your answer.

Salim needs at least 700 clicks per month  in order to earn $50 per month or more

A linear equation is in the form:

y = mx + b;

where y, x is variable, m is the rate of change and b is the y intercept.

Let y represent the total pay Salim earns and x represent the number of clicks.

Salim's Website earns $15 per month plus $0.05 every time a visitor clicks, hence:

y = 0.05x + 15

To earn for than $50 per month:

0.05x + 15 > 50

0.05x > 35

x > 700

Hey there!

We can let x be that number.

2x+9=31

2x=22

x=11

The number is 11.

Let me know if this helps :)

Answer:

The whole number is 11.

Step-by-step explanation:

Let's call the whole number x. We can write the following equation:

2x + 9 = 31

Subtracting 9 from both sides of the equation gives us:

2x + 9 - 9 = 31 - 9

2x = 22

Dividing both sides of the equation by 2 gives us:

2x / 2 = 22 / 2

x = 11

Answer:

(A) 70°

(B) 67°, because they are alternate interior angles

Step-by-step explanation:

For a:

The angles of a triangle will all add up to 180°. Using the "feathers" (lines that signify congruence), we can tell that the angle connecting the two congruent lines will be different than the other two, which will be equivalent to each other.

This means that the angle measure of x will be [tex]180-55-55[/tex], or just [tex]180-110[/tex].

This is equal to 70°.

For b:

We know that the 67° angle and y are formed by the same line intersecting two parallel lines. This means that the angle measures of each intersection point will be the same as the other intersection point, however they will be flipped. This makes the concept of alternate interior angles. We know that the 67° angle and y are formed by the same line, this means that their angle lengths are the same - therefore y is 67°.

Answer:

v = 0.834 m/s or 3 km/h

Step-by-step explanation:

Given that,

Distance between house and playground is 300 meters

If you went 300  metres away in 10 minutes and ran back and  reached in 2 minutes, it means total distance covered by you during whole journey is 300 m + 300 m = 600 m

Total time, t = 10 min + 2 min = 12 min = 720 seconds

Total distance covered divided by total time gives average speed. So,

[tex]v=\dfrac{600\ m}{720\ s}\\\\v=0.834\ m/s[/tex]

or

v = 3 km/h

So, the average speed is 0.834 m/s or 3 km/h.

Answer:

Answer is 900.

Step-by-step explanation:

To find:

Increase #500 in the ratio 16:10

Solution:

New Number: Old Number = 16:10

We are given the old number as 500.

Let the new number after increase = [tex]x[/tex]

Now, using the above ratio:

[tex]x[/tex]: 500 = 16:10

[tex]\dfrac{x}{500} = \dfrac{16}{10}\\\Rightarrow x = 500 \times \dfrac{16}{10}\\\Rightarrow x = 50 \times 16\\\Rightarrow x = 900[/tex]

Therefore, the increased value of 500 in the ration 16:10 is 900.
