Answers

Answer:

43.94?

Step-by-step explanation:

I think if you use inverse cos you should get the correct number. So, to find cos, you need to know the adjacent side and the hypotenuse. Here, the reference angle would be the person holding the kite. The distance from the person to the barn is the adjacent side, which is 18. The string of the kite, I assume, would be 25.

cos(∅) = [tex]\frac{18}{25}[/tex]

cos(∅) = 0.72

cos⁻¹(0.72) = 43.94

I don't know if that's what you're looking for, but... If it's not correct, lmk so I can rewrite it. :)

P < 4.75 represents the prices p in dollars that Paige is willing to pay for popcorn. The inequality p < 8.00 represents the prices p in dollars that Paige is willing to pay for a movie ticket. At how many theaters would Paige be willing to buy a ticket and popcorn?

Answers

Answer:

1 theater

Step-by-step explanation:

Given

[tex]P<4.75[/tex] --- Popcorn

[tex]P < 8.00[/tex] --- Movie

See attachment for the table that shows ticket and popcorn prices at five movie theater chains

Required

The number of theaters that supports the given inequality

The given inequality can be combined to give:

[tex]P < 4.75\ and\ P<8.00[/tex]

From the table entries, only one theater supports this inequality.

Where

[tex]P = 4.25[/tex] --- Movie

[tex]P = 7.25[/tex]  --- Popcorn

Which gives:

[tex]4.25 < 4.75\ and\ 7.25<8.00[/tex]

Given that R=7x+5Y find Y when X=9 and R=35 give your answer as an improper fraction in its simplest form


Please help

Answers

Answer:

y = -28/5

Step-by-step explanation:

R = 7x +5y

35 = 7(9) + 5y

35 = 63 +5y

-5y= 63- 35

-5y/-5 = 28/-5

Y = -28/5

Answer:

Y = - [tex]\frac{28}{5}[/tex]

Step-by-step explanation:

Given

R = 7X + 5Y ← substitute X = 9, R = 35

35 = 7(9) + 5Y

35 = 63 + 5Y ( subtract 63 from both sides )

- 28 = 5Y ( divide both sides by 5 )

- [tex]\frac{28}{5}[/tex] = Y

simplify as far as possible:3x+4y+7y​

Answers

Answer:

Step-by-step explanation:

We need to simplify the given expression i.e.

3x+4y+7y

We know that, the like terms gets add up i.e. the sum of 4y and 7y equals 11 y
