AysviL [449]

Answer:

The height of the taller building is 64\ ft

Step-by-step explanation:

see the attached figure to better understand the problem

step 1

Find the value of h1

with the angle of elevation

we know that

tan(20\°)=\frac{h1}{60}

h1=60*tan(20\°)

step 2

Find the value of h2

with the angle of depression

we know that

tan(35\°)=\frac{h2}{60}

h2=60*tan(35\°)

step 3

Find the height of the taller building

The height of the taller building is the sum of h1 plus h2

so

60*tan(20\°)+60*tan(35\°)=60*(tan(20\°)+tan(35\°))=64\ ft

There are 750 many outcome pairs you can have

<h3>How to determine the number of outcome pairs?</h3>

The given parameters are:

Website 1 = 25

Website 2 = 30

The number of outcome pairs is calculated as:

Outcome = Website 1 * Website 2

So, we have:

Outcome = 25  * 30

Evaluate the product

Outcome = 750

Hence, there are 750 many outcome pairs you can have

miley has d decks of playing cards. write an equation for a function that shows how many c cards miley has all together if each
anastassius [24]
Answer is C= 52d
To solve problems like this, you would just need to think about what the question is asking you one step at a time
List what you know
- There are 52  cards in each deck
- We need how many cards in total

So let us think about it from a mathematical standpoint
1 deck= 52 cards         1 x 52= 52
that means.....
2 deck= 104 cards      2 x 52 = 104
3 deck= 158 cards      3 x 52 = 158
and the list keeps going
That means that 52 multiplied by whatever number d is will get you the total number of cards.
thus C= 52d
