To figure out the answer to problems such as these, all we need to do is some simple division.

To get the amount of minutes it took Walter to walk to his friend's house each day, we must divide the 184 minutes by 8.

184 / 8 = 23

There's your answer. It took Walter 23 minutes to walk to his friend's house each day.

Factorise 15x+25<br><br>thank you for any help​
scoray [572]

Answer: 5(3x+5)

Step-by-step explanation:

To factor this expression we need to pull out the greatest common factor of the 2 numbers, 15 and 25. This factor is 5.

Now divide both numbers by 5 and put a 5 on the outside of the new expression to look like: 5(3x+5) and this is as far as it can be factored.

PLEASE GIVE AN EXPLANATION!! In your grade of 380 students, 70% play a musical instrument. 60% of the boys play a musical instru
Liula [17]

Answer:

270 girls

Step-by-step explanation:

Total number of students = 380

Play musical instrument = 70%

Boys who play musical instrument = 60%

Number of girls who play musical instrument = 200

How many girls are in the class?

Number of play musical instrument = 70% of 380

(0.7 * 380) = 266

Since number of girls who play musical instrument = 200

Then number of boys who play = (266 - 200) = 66

Hence, 66 boys is equivalent 60% of the boy's population

Let population of boys = b

0.6b = 66

b = 110

Number of girls in class :

Number of boys + number of girls

110 + number of girls = 380

Number of girls = 380 - 110

Number of girls = 270

Over the last 50 years, the average temperature has increased by 2.5 degrees worldwide (I made this up). What is the rate of cha
Dovator [93]
50 years ... 2.5 degrees
1 year ... x degrees = ?

If you would like to know what is the rate of change in worldwide temperatures per year, you can calculate this using the following steps:

50 * x = 2.5 * 1
50 * x = 2.5      /50
x = 2.5 / 50
x = 0.05 degrees per year

Result: The rate of change is 0.05 degrees per year.

Suppose the graph of a cubic polynomial function has the same zeroes and passes through the coordinate (0, -5). Write the equati
amid [387]
In this we know all three zeros and one point from which the graph pass.
So we will let specific cubic polynomial function of the form
f(x) = a(x - x_1)(x-x_2)(x-x_3)

As we know zeros are that point where we will get value of function equal to zero. So it is basically in form (x_n , 0)

SO in given question zeros are (2 , 0) , (3, 0) and (5,0)
So we can say x_1 = 2 , x_2 = 3 , x_3 = 5

So required equation is
f(x) = a (x-2)(x-3)(x-5)
              = a[(x^2 - 2x - 3x + 6)(x-5)]
              = a[(x^2 - 5x+6)(x-5)]
              = a(x^3 - 5x^2 + 6x- 5x^2 + 25x - 30)
              = a(x^3 - 10x^2+31x-30)
Now we have one point (0 , -5) from which graph passes.
So we say at x = 0 , f(x) = -5
-5= a (0-0+0 - 30)
-5 = -30a
a =  \frac{-5}{-30} =  \frac{1}{6}
So required equation of cubic polynomial is
f(x) =  \frac{1}{6}(x^3 -10x^2+31x-30)

For finding y - intercept we simply plugin x = 0 in given equation.
As we know at x = 0 , value of function is -5.
So y - intercept is -5.
