A light tower is going to be installed on the left edge of the Skywalk as indicated in the diagram above. The light will shine down to the opposite edge of the Skywalk indicated with the star in the diagram above. How tall does the light tower need to be if the angle of depression is 51°?

Answers

Answer 1

The diagram indicating the light tower is below.

Answer: Tower has to be 86.45 ft high.

Step-by-step explanation: The second attachment shows the right triangle formed by the tower, the floor and the point the light will shine.

Using trigonometric relations among the angle and the sides of the triangle we will have:

[tex]tan(51)=\frac{h}{70}[/tex]

h = 70*tan(51)

h = 86.45

The tower has to be 86.45 ft tall for the angle of depression to be 51°

Answer:

20L + 45 = 225

Step-by-step explanation:

20 is the slope making it constant

45 is a one time fee making it a y intercept

equaling 225

Answer:

20L+45=225

Step-by-step explanation:

20 represents how much she paid for each lesson, we don't know how many lessons she paid for so we use the variable L and multiply it by 20. She only had to pay the registration fee once so 45.  Unknown lessons taken by  20 + the one-time fee of 45 equals 225

The discount price of a book is 20% less than the
retail price. James manages to purchase the book
at 30% off the discount price at a special book
sale. What percent of the retail price did James
pay?
A) 42%
B) 48%
C) 50%
D) 56%

Answers

Answer:

Step-by-step explanation:

Let retail be $100

At 20% discount

(100-20)% * 100

0.8*100

$80

At 30% discount

(100-30)%* 80

$56

Using the percentage relationship between cost, the book was purchased at 56% of the retail price.

Let :

Retail price = r

Discount price = 0.8r

Special sale price :

30% off discount price

(1 - 0.30) × 0.8r

0.70 × 0.80r = 0.56r

Hence, the book was purchased at 56% of the retail price.

Write a fraction that is less than 1/3 using 1 as the numerator. EXPLAIN why you chose that answer.​

Answers

1/4 would be the answer because when you have 1/3, you would only have 3 parts to get a whole, but in 1/4, you would have 4 parts to get a whole.

A fraction which is less than 1/3 is 1/6

How to find quantities which are less than a given quantity?

We can lessen a quantity if we take out some positive part from it.

Thus, suppose if it is given that there are 'T' things, then a quantity which is less than 'T' would be 'T - S'

where S is something positive.

(there can be infinite number of values less than a specific finite value, and similarly, there can be infinite number of values more than a specific finite value).

For the given case, the fraction given is 1/3

Let a fraction which is less than it be denoted by F

Then,

[tex]F < 1/3\\F = \dfrac{1}{3} - S[/tex]

Let S = 1/6

Then, we get value of F as:

[tex]F = \dfrac{1}{3}- \dfrac{1}{6} = \dfrac{2 - 1}{6} = \dfrac{1}{6}\\[/tex]


Thus, 1/6 is a fraction which is less than the given fraction 1/3

Answer:

  x = 3.6

Step-by-step explanation:

The angle bisector divides the triangle proportionally.

The base segment to the right of the bisector is 6-x, so we can write the proportion ...

  x/6 = (6-x)/4

Multiplying by 12, we get ...

  2x = 3(6 -x)

  5x = 18 . . . . . add 3x

  x = 18/5 . . . .  divide by 5

  x = 3.6

_____

Alternate solution

Since the base of the triangle is given as a left-part and a sum-of-both-parts, we can write the proportion the same way:

  left-part / sum-of-both-parts = x/6 = 6/(6+4)

Then the solution is x = 6(6/10) = 36/10 = 3.6.

Doing it this way avoids having x on both sides of the equation, so makes solving the equation be "one step."

8. The number of T-shirt sales for a new online store increases by a factor of 3
each month. The function f(x) = 3x
represents the number of T-shirts sold in
month x.
a. What is f(5)?
b. When does the store sell 81 T-shirts?

Answers

Answer:

A= 243

B=4

Its because its multiplying itself 5 times for A. And doing it 4 times for B

I think this is correct (I am only in Middle School...)

Step-by-step explanation:

(a) The number of T-shirts sold in the 5th month is 15. (b) The store sells 81 T-shirts in the 27th month.

a. To find f(5), we need to plug x = 5 into the function f(x) = 3x:

f(5) = 3 × 5 = 15

So, the number of T-shirts sold in the 5th month is 15.

b. To find when the store sells 81 T-shirts, we need to solve the equation f(x) = 81:

f(x) = 3x = 81

Now, solve for x:

3x = 81

Divide both sides by 3:

x = 81 / 3

x = 27

So, the store sells 81 T-shirts in the 27th month.

so, I will solve both of them.

Answer:

Please check the explanation.

Step-by-step explanation:

1)

[tex]4x+5y^3=-7[/tex]

Assuming the equation

[tex]4x+5y^3=-7[/tex]

substituting x = -4 and y = 2

[tex]4\left(-4\right)+5\left(2\right)^3=-7[/tex]

[tex]-16+2^3\cdot \:\:5=-7[/tex]

[tex]-16+40=-7[/tex]

[tex]24=-7[/tex]

False!

The sides are not equal!

Since (-4, 2) does not satisfy the equation, therefore (-4, 2) is not a solution of [tex]4x+5y^3=-7[/tex].

2)

[tex]4x+5y=-37[/tex]

Assuming the equation

[tex]4x+5y=-37[/tex]

substituting x = -4 and y = 2

[tex]4\left(-4\right)+5\left(2\right)=-37[/tex]

[tex]-16 + 10 = -37[/tex]

[tex]-6=-37[/tex]

False!

The sides are not equal!

Since (-4, 2) does not satisfy the equation, therefore (-4, 2) is not a solution of [tex]4x+5y=-37[/tex].
