Julie is 6 feet tall. If she stands 15 feet from the flagpole and holds a cardboard square, the edges of the square line up with the top and bottom of the flagpole. Approximate the height of the flagpole

Answers

Answer 1

Answer:

43.5 ft

Step-by-step explanation:

Given: Julie is 6 feet tall

           She stands 15 feet from the flagpole.

           The edges of the square line up with the top and bottom of the flagpole.

Picture drawn to show side and angle formed by Julie and flagpole.

Lets assume the height of flagpole be "h".

As given, the edges of the square line up with the top and bottom of the flagpole.

∴ Angle and base of triangle are same then ratio of corresponding sides are also equal.

Now, finding the height of flagpole by using tangent rule.

we know, [tex]tan\theta= \frac{Opposite}{adjacent}[/tex]

Remember, both the angle are equal.

∴ Ratio of opposite and adjacent leg for both right angle triangle= [tex]\frac{6}{15} : \frac{h-6}{15}[/tex]

We can put it; [tex]\frac{6}{15} = \frac{15}{h-6}[/tex]

Solving the equation now

⇒ [tex]\frac{6}{15} = \frac{15}{h-6}[/tex]

Multiplying both side by 15

⇒[tex]6 = \frac{15\times 15}{h-6}[/tex]

Multiplying both side by (h-6)

⇒ [tex]6\times (h-6) = 15\times 15[/tex]

Distributive property of multiplication

⇒ [tex]6h-36= 225[/tex]

Adding both side by 36

⇒[tex]6h= 225+36[/tex]

Dividing both side by 6

⇒[tex]h= \frac{261}{6}[/tex]

∴ [tex]h= 43.5\ feet[/tex]

Hence, the height of flagpole is 43.5 feet.

 Julie Is 6 Feet Tall. If She Stands 15 Feet From The Flagpole And Holds A Cardboard Square, The Edges
Answer 2

The height of the flagpole is given by the length of the hypotenuse side

formed by the right triangle Julie forms with the cardboard.

Response:

Height of the flagpole is 17.4 feet

Which method is used to calculate the height of the flagpole?

The triangle formed by the edges of square lined up with the top and

bottom of the flagpole is a right triangle.

The altitude of the right triangle formed with the height of the flagpole as the base = 15 feet

Length of a leg of the right triangle = √(15² + 6²) = 3·√(29)

The other angle formed by the right triangle = (90° - arctan(15/6))

h × sin(arctan(15/6)) = 3·√29

[tex]h = \mathbf{\dfrac{3 \cdot \sqrt{29} }{sin(arctan(15/6))} } = 17.4[/tex]

Height of the flagpole, h = 17.4 feet

On Tuesday James bought seven CDs. On Wednesday half of all the CDs that he had were destroyed. On Thursday he had 12 left. How many did he have on Monday?

Answers

Answer:

He have 17 CDs on Monday.

Step-by-step explanation:

Given:

On Tuesday James bought seven CDs. On Wednesday half of all the CDs that he had were destroyed. On Thursday he had 12 left.

Now, to find the CDs he have on Monday.

Let the CDs he have on Monday be [tex]x.[/tex]

So, on Tuesday as James bought 7 CDs:

[tex]x+7.[/tex]

Now, on Wednesday half of all the CDs that he had were destroyed:

[tex]\frac{x+7}{2}[/tex]

As, given on Thursday he had left CDs = 12.

According to question:

[tex]\frac{x+7}{2}[/tex] [tex]=12[/tex]

Multiplying both sides by 2 we get:

[tex]x+7=24[/tex]

Subtracting both sides by 7 we get:

[tex]x=17.[/tex]

Therefore, he have 17 CDs on Monday.

Natasha has a red and a white sweater. She can wear with a blue skirt, yellow skirt and a black skirt. How many different combinations can she make

Answers

Final answer:

Natasha can make 6 different combinations by pairing 2 sweaters with 3 skirts. She can pair each of her red and white sweaters with each of her blue, yellow, and black skirts.

Explanation:

Natasha has a red sweater and a white sweater that she wants to pair with a blue skirt, yellow skirt, and a black skirt. To determine the number of different combinations she can make, we use basic combinatorics. Each sweater can be paired with any of the skirts, so we multiply the number of sweaters by the number of skirts.

Here is the calculation:

Number of sweaters: 2 (red and white)Number of skirts: 3 (blue, yellow, and black)

Thus, Natasha can make 2 sweaters  imes 3 skirts = 6 combinations.

These combinations are:

Red sweater with blue skirtRed sweater with yellow skirtRed sweater with black skirtWhite sweater with blue skirtWhite sweater with yellow skirtWhite sweater with black skirt

what is 1.498 divived by 30. plz show your work.

Answers

Answer:

[tex]0.0749[/tex]

Step-by-step explanation:

[tex]1.498/30[/tex]

To divide the form directly in fraction divide the numerator and denominator by a common number to simplify the values.

Simplifying the value  

    Removing the decimal in the numerator makes 1000 in denominator

                                               [tex]\frac{1498}{30}*\frac{1}{1000}[/tex]

dividing by a common value i.e 2                            

                                         [tex]\frac{749}{10}*\frac{1}{1000}[/tex]

Now, removing the decimals from denominator puts the decimal in the numerator gives   [tex]0.0749[/tex]

Answer:

1.498 divided by 30 equals 749/15000 OR 0.04993

Step-by-step explanation:

Simply divide as you would a whole number, but place the decimal point above in your answer. So, your first step would be to calculate how many times 30 goes into 149. Your answer will go two places AFTER your decimal point. Then you continue to solve, as you would a whole number!

Some of the laws of exponents are:

You can add and subtract both sides of inequality by a number without change the sign of inequalityYou can multiply or divide both sides of inequality by a positive number without change the sign of inequalityYou can multiply or divide both sides of inequality by a negative number with change the sign of inequality (-2x < 4 ⇒ ÷ (-2) makes it x > -2)

∵ -4 h - 3 < 9

- Start with adding both sides by 3 to separate the variable

   in one side and the numerical term in the other side of the

Why does 5x2/3 =10x1/3

Answers

Explanation of how to simplify expressions with exponents by subtracting exponents. The answer shows the equivalence of 5×2/3 and 10×1/3.

The expression [tex]( \frac{5 \times 2}{3} )[/tex] equals [tex]( \frac{10}{3} )[/tex].  Let's break it down:

[tex]\( \frac{5 \times 2}{3} \)[/tex] means you multiply 5 and 2 first, which gives you 10, then you divide by 3, resulting in [tex]\( \frac{10}{3} \)[/tex].

However, if you're asking why [tex]\( \frac{5 \times 2}{3} \)[/tex] and [tex]\( 10 \times \frac{1}{3} \)[/tex] are equal, it's because multiplication is distributive over division.

In other words, [tex]\( a \times \frac{b}{c} = \frac{a \times b}{c} \)[/tex].

So, [tex]\( 10 \times \frac{1}{3} \)[/tex] can be written as [tex]\( \frac{10 \times 1}{3} \)[/tex], which simplifies to [tex]\( \frac{10}{3} \)[/tex], the same as [tex]\( \frac{5 \times 2}{3} \)[/tex].

Answers

Answer:

6n

Step-by-step explanation:

Final answer:

The difference of 5 and n cubed is calculated by subtracting n cubed from 5. This involves simple algebraic manipulation.

Explanation:

The difference of 5 and n cubed can be represented as 5 - n³. This means subtracting the cube of the variable n from 5.

To illustrate, if n=2, the calculation would be 5 - 2³ = 5 - 8 = -3.

Therefore, the result of the difference between 5 and n cubed is 5 - n³.

The difference between of two numbers is 9. If the large number is one more than twice the smaller number, find the larger number.

Answers

The larger number is 17

Solution:

Let "x" be the larger number

Let "y" be the smaller number

The difference between of two numbers is 9

Therefore,

larger number - smaller number = 9

x - y = 9 -------- eqn 1

The large number is one more than twice the smaller number

Larger number = 1 + 2(smaller number)

x = 1 + 2y ------ eqn 2

Let us solve eqn 1 and eqn 2

Substitute eqn 2 in eqn 1

1 + 2y - y = 9

1 + y = 9

y = 9 - 1

y = 8

Substitute y = 8 in eqn 1

x - 8 = 9

x = 8 + 9

x = 17

Thus the larger number is 17

Step-by-step explanation:

Briana has been offered a sales job in another city

The offer was for $42,500 plus 8% of her total salesBriana needs to have an annual salary of at least $66,500

We need to find what would her total sales need to be for her to move

Assume that her total sales is x

∵ The offer was for $42,500 plus 8% of her total sales

∵ Her total sales = x

- To find her annual salary multiply x by 8% and add the

  product to $42,500

∴ Her annual salary = 8% × x + 42,500

∵ 8% × x = [tex]\frac{8}{100}[/tex] × x = 0.08 x

Her annual salary = 0.08 x + 42,500

∵ Briana needs to have an annual salary of at least $66,500

- At least means ≥

∴ Her annual salary ≥ 66,500

- Substitute her annual salary by the expression above

0.08 x + 42,500 ≥ 66,500

- Subtract 42,500 from both sides of inequality

∴ 0.08 x ≥ 24,000

- Divide both sides by 0.08

x ≥ 300,000

∴ Her total sales ≥ $300,000

Her total sales would need to be at least $300,000 for her to move
