Answer:

P = $1.50c - $12

Step-by-step explanation:

profit = total revenue - total cost

total revenue = price per cup x total cup sold = $1.5 x c = 1.5c

Cost = $12

Angle 0 is in the second quadrant, and sin 0=3/5
Aneli [31]
ANSWER


The value of theta in the second quadrant is,

143.1 \degree


EXPLANATION

The given trigonometric equation is
\sin( \theta)  =  \frac{3}{5}


This implies that,


\theta=  arcsin(\frac{3}{5} )


This implies that the principal solution is
\theta =  36.9 \degree
and it is an angle in the first quadrant.

But the solution we are looking for is an angle in the second quadrant.



This is given by
180 -  \theta = 180 - 36.9 = 143.1 \degree

For the data in the table tell whether y varies directly with X if it does write an equation for the direct variation
frozen [14]

a) Option B Direct variation, y=1.8x is correct option.

b) Option A Not a direct variation is correct option.

Step-by-step explanation:

a) for the data in the table tell whether y varies directly with X if it does write an equation for the direct variation

The direct variation is represented by:

y=kx \,\,or\\\frac{y}{x}=k

We need to find k.

Given the values of x and y in table we will find k. if value of k is constant, so x and y varies directly

\frac{5.4}{3}=1.8\\\frac{12.6}{7}=1.8\\\frac{21.6}{12}=1.8

Since value of k is constant i.e 1.8 so, y varies directly with x.

Option B Direct variation, y=1.8x is correct option.

b) For the data in the table tell whether Y varies directly with x if it does write an equation for the direct variation.

The direct variation is represented by:

y=kx \,\,or\\\frac{y}{x}=k

We need to find k.

Given the values of x and y in table we will find k. if value of k is constant, so x and y varies directly

\frac{1}{-2}=-\frac{1}{2}\\\frac{6}{3}=2\\\frac{11}{8}=1.3

Since value of k is not constant  so, y doesn't varies directly with x.

Option A Not a direct variation is correct option.

The question of two numbers is eight the sum of the same two numbers is 72 what are the two numbers
Otrada [13]

Answer:

The two numbers are 64 and 8.

Step-by-step explanation:

You meant "quotient" of two numbers, right?

Represent the numbers by x and  y.

Then the quotient is x/y = 8, and beyond that we know that x + y = 72.

Solve this for x and y.  

If x/y = 8, then x = 8y.  Substituting this into x + y = 72, we get:

(8y) + y = 72, or 9y = 72.  Dividing both sides by 9 yields y = 8.

Since x/y = 8, letting y = 8 results in x = 64.

The two numbers are 64 and 8.

URGENT WILL GIVE BRAINLIEST TO FIRST RESPONDER You are visiting a Redwood tree forest and want to verify the height of one of th
pickupchik [31]

Answer:

a) 55 degrees

b) 350 ft.

Step-by-step explanation:

a- the sum of angles of triangle=180

( since it is right angle , one angle is 90 degrees), x be the acute angle

x+35+90=180

x=180-125

x=55 degrees

b) tan 35= height of a tree/ length of a shadow

height of a tree=tan35*500=350.103≅350 ft ( rounded to nearest tens)

c)  hypotenuse²=350.1²+500²

c=√350.1²+500²

c=610.385 ft

d) no because the distance is more than 500
