B) 1 5/8 feet per hour
C) 1 7/8 feet per hour
D) 2 7 /8 feet per hour

Answers

b because you don’t multiply the denominator, so you mulitply the top by 5, to get 15 and put it over 8. so 15/8

Answer:

B) 1 5/8 feet per hour is your answer

3/8foot=1/5hour

15foot =8hour

Answer:

  437.3 ft

Step-by-step explanation:

The angle of depression can be copied inside the triangle to the angle of elevation (at lower right). Then the side x can be seen to be adjacent to the angle.

The mnemonic SOH CAH TOA reminds you of the relations. Here, we have the hypotenuse and we want the adjacent angle. The relevant relation is ...

  Cos = Adjacent/Hypotenuse

  cos(29°) = x/(500 ft)

Multiplying by 500 ft gives ...

  x = (500 ft)cos(29°)

  x ≈ 437.3 ft

_____

Additional comment

You have posted a number of problems that make use of this geometry. They are all solved the same way:

  a) identify the desired measure and the given measures

  b) using SOH CAH TOA, identify the relation applicable to those measures

  c) fill in the given values in the equation

  d) solve for the unknown

You may need to make use of what you know about angles and triangles in order to relate given angles to ones you need to use.

how do you solve the system:
y+1=2x
5y+5=10x

Answers

Answer:

choose "infinitely more solutions"

Step-by-step explanation:

Let's solve this system by substitution method

y+1=2x

- 1 = - 1

y = 2x -1   <-- sbstitute this in the next equation

---------------------------------------------------------------------------------

    5y+5 = 10x

5(2x -1) + 5 = 10x

10x -5 + 5 = 10x

10x + 0= 10x

- 10x = -10x

0 = 0      <-- infinitely more solutions

Answer:

5+5=10x
