Brainliest pls??

Answer:

The song fully played 225 times.

Step-by-step explanation:

Really? What a question.

Between 10:55 pm and 9:50 am, 13 hours and 5 minutes elapse.

For us to calculate how many times the song played, we need to convert them to the same units, i.e. seconds.

3 minutes and 29 seconds = 209 seconds

13 hours and 5 minutes = 47100 seconds

If 47100 seconds elapsed and the song was playing on repeat the whole time, we can calculate how many times it played by:

47100/209 = 225.36 (approximation to the nearest hundredth)

So, the song fully played 225 times.

A train travels train travels 288 kilometre at a uniform speed. If the speed had been 4 kilometre per hour more it would have ta
kiruha [24]

Answer:

Let the speed of the train be x km/h.

Case 1:

Distance = 288 km

Speed = x km/h

Time = Distance/Speed

= 288/x h

Case 2:

Distance = 288 km

Speed = (x+4) km/h

Time = 288/x + 4 h

Since 288/x > 288/x + 4

288/x - 288/x+4 = 1

288[1/x - 1/x+4 ] = 1

[ x + 4 - x / x(x + 4) ] = 1/288

[4 / x^2 + 4x ] = 1/288

x^2 + 4x = 1152

x^2 + 4x - 1152 = 0

x^2 + 36x - 32x - 1152 = 0

x(x + 36) - 32(x + 36) = 0

(x + 36)(x - 32) = 0

x + 36 = 0 , x - 32 = 0

x = -36 , x = 32

x = -36 , rejected since speed cannot be negative.

Therefore , speed of the train = 32 km/h

Answer number 2 pleaseeee thank you
Fittoniya [83]

Hi!

a: <em>F </em><em>n </em><em>G </em>=(Intersection) {4,6,8,10}

b: <em>F </em><em>n </em><em>H </em>={empty set}

Because there is no common element between the elements of set F and the elements of set H.

Note: It may not be very clear as I don't speak English.

God work!

What is the justification for each step in solving the inequality? -5(4x+6&lt;-18x+6+4x
Daniel [21]
Hi there!

Everything looks correct except for the step to get to -6x < 36. Here you put multiplication property of order, and to get here you have to add 30 to both sides, so it would actually be the addition property of order.

I hope I helped!

Find the quotient. x + 7 x ÷ 9 x
kicyunya [14]
The first step for solving this expression is to write the division as a fraction.
x + \frac{7x}{9} × x
Calculate the product.
\frac{7x X x}{9}
Remember that if a term doesn't have an exponent,, it is considered that the exponent for that term is 1. This changes the expression to the following:
\frac{7 x^{1}X x^{1}  }{9}
Now multiply the terms with the same base by adding their exponents.
\frac{7 x^{1+1}}{9}
Finally,, add the numbers together to get your final answer.
x + \frac{7 x^{2}}{9}
Let me know if you have any further questions.

Brainliest for correct answer! :)
professor190 [17]

Answer:

Mode: 44 (mode is biggest number)

Mean: 30 (the average between numbers)

Step-by-step explanation:

Calculating the Mean

44 + 43 = 87

25 + 8 = 33

87 + 33 = 120

120 + 30 = 150

150/5 = 30
