Answer:

4π

Step-by-step explanation:

4x² + 9y² = 36

Divide all  through by 9

4/9x² + ²y² = 44

\int\limits^3_0 {\pi y^{2} } \, dx

\int\limits^3_0 {4-\frac{4}{9} }x^{2}  \, dx

It takes 52 minutes for five people to paint five walls how many minutes does it take 20 people to paint 20 walls hi
AlexFokin [52]

Answer:

52 minutes

Step-by-step explanation:

Given in question as

Men 1 = 5                                                          Men 2 = 20

Work 1 = 5                                                        Work 2 = 20

Time 1 = 52 min                                               Time 2 = T 2

Now , we can solve by equating them

i.e \frac{Men1 * Time1}{work1} = \frac{Men2 * Time 2}{Work2}

Or, \frac{5 * 52}{5} = \frac{20 * T2}{20}

Or T2 = 52 min  Answer

The proportion pop/total = 5/7 is presumed to hold for the next 500 songs.

pop/500 = 5/7
pop = 500*5/7 ≈ 357

357 of the next 500 songs downloaded are expected to be pop songs.

The cosine ratio is adjacent leg divided by the hypotenuse.
The hypotenuse in a right triangle is the longest side and it is opposite the right angle.
An adjacent leg is the side that has an endpoint that is at the vertex of the angle and the other endpoint is at the vertex of the right angle.

cos A = \frac{12}{20} =  \frac{3*4}{5*4} = \frac{3}{5}
ANSWER: cosA= \frac{3}{5}

What are the x-intercepts and the y-intercepts of the graph of 12x−3y=36
nikklg [1K]

Answer:

Step-by-step explanation:

12x −3y=36  ⇔ 3y = 12x - 36

                          y = 4x - 12

y = 0 ⇔ 4x - 12 = 0 ⇔ 4x = 12 ⇔ x = 12/4 = 3

So (0 ; - 12) and (3 ; 0)

Answer:

Step-by-step explanation:

Alright, lets get started.

Lets find slope for both bikes one by one

For bike 1 :

There are two points on the graph of Bike 1, these two points are (2,3) and (4,6)

So the slope for bike 1 is : \frac{y_{2}-y_{1} }{x_{2}-x_{1} }

So the slope for bike 1 is : \frac{6-3}{4-2}

So the slope for bike 1 is : \frac{3}{2}

For bike 2 :

There are two points on the graph of Bike 2, these two points are (4,5) and (8,10)

So the slope for bike 2 is : \frac{y_{2}-y_{1} }{x_{2}-x_{1} }

So the slope for bike 2 is : \frac{10-5}{8-4}=\frac{5}{4}

Hence Bike 1 will win the race as slope of line bike1 is greater than slope of line bike 2.  So, answer is option D
