Spongebob Squarepants is watching King Kong climb the Voice of America

radio tower. Spongebob is 80 meters away from the tower. He looks up at

King Kong with an angle of elevation of 23º. Find King Kong's height to the

nearest tenth of a meter.

Answers

Answer 1

Answer:

127.1 m

Step-by-step explanation:

We are given the value of the adjacent side and we are to find the value of the opposite side

Tan would be used to determine this value

Tan 23 = opposite / adjacent

1.5882 = x / 80

x = 80 x 1.5882

x = 127.056 m

x = 127.1m

the tenth is the first number after the decimal place. To convert to the nearest tenth, look at the number after the tenth (the hundredth). If the number is greater or equal to 5, add 1 to the tenth figure. If this is not the case, add zero

Please find attached a diagram showing the angle of elevation

Which expression is equivalent to (6x3+3x2+8)+(2x2−9x+10)?

Answers

Answer:

Which expression is equivalent to (6x3+3x2+8)+(2x2−9x+10)?

Step-by-step explanation:  

6x3+3x2+8)+(2x2−9x+10)?

The equivalent expression is 6x^3+5x^2-9x+18.

What is an algebraic expression?

An expression which is made up of variables and constants, along with algebraic operations (addition, subtraction, etc.). Algebraic expressions include at least one variable and at least one operation.

For the given situation,

The expression is [tex](6x^3+3x^2+8)+(2x^2-9x+10)[/tex]

⇒ [tex]6x^{3}+3x^{2} +8 +2x^{2} -9x+10[/tex]

Rearrange the expression in decreasing order of polynomial,

⇒ [tex]6x^{3}+3x^{2}+2x^{2} -9x+8+10[/tex]

Now add the like terms,

⇒ [tex]6x^{3} +5x^{2} -9x+18[/tex]

Hence we can conclude that the equivalent expression is [tex]6x^{3} +5x^{2} -9x+18[/tex].

What’s the value of x

Answers

Answer:

x = 2

Step-by-step explanation:

According to the inscribed Angle Theorem, the size of an inscribed angle = ½(measure of the intercepted arc)

m<L = (7x + 9)° is an inscribed angle

m(KM) = 46° is its intercepted arc

Therefore:

7x + 9 = ½(46)

Multiply both sides by 2

2(7x + 9) = 46

14x + 18 = 46

14x + 18 - 18 = 46 - 18

14x = 28

14x/14 = 28/14

x = 2

If 35 people going to the movie bought popcorn and that was 20% of all the people at the movie how many people were at the movie

Answers

Answer:  

Im pretty sure it would be 700 but im most likely wrong.

The correct answer is 175

If 35 people is 20% of all people, we can assume that 35 is 1/5 of all the people at the movie since 20% is 1/5 of 100%


All we have to do is multiple 35 by five.



I can prove my answer by dividing 175 by 5 which would give me 20% of 175

Whats the slope of the line?

Answers

Answer:

m = rise/run = 4/5.

Step-by-step explanation:

This line goes throught the "exact" grid intersections (-2, 0) and (3, 4).  As we move from the first point to the second, we see that x increases by 5 (this is the 'run') and y increases by 4 (this is the 'rise').  Thus, the slope of this line is m = rise/run = 4/5.
