Answer:

9:20 A.M.

Step-by-step explanation:

Let's list out the points at which the 25-minute bell rings:

25 mins, 50 mins, 1 hour 15 mins, 1 hour 40 mins,  2 hours 5 mins, 2 hours 30 mins, 2 hours 55 mins, 3 hours 20 mins

Next let's list out the points at which the 40-minute bell rings:

40 mins, 1 hour 20 mins, 2 hours, 2 hours 40 mins, 3 hours 20 mins

From the lists above we see a common multiple of 3 hours and 20 minutes.

So, to find what time they ring after 6 A.M. add 3 hours and 20 minutes to it.

6 AM + 3 hours and 20 minutes = 9:20 A.M.

Thus, both bells would ring together again at 9:20 A.M.

Hope this helps!!

A student writes the equation for a line that has a slope of -6 and passes through the point (2, –8). y -(-8) = -6(x - 2) y -(-8
Mice21 [21]
Y - (-8) = -6 (x-2) is correct everything else is not
y + 8 = -6x + 12
y +:8 - 8 = -6x + 12 - 8
y = -6x + 4 is slope intercept form

Nataly_w [17]

Answer:

You will use the z score to find this so need a z score chart.

Step-by-step explanation: Remember to take what you want (35 ounce) minus the mean( 29) then divide by the standard deviation(4). Then you look up this number on the z score chart to find your probability of less than 35 ounces. You could then do the same thing using 34 ounces since your final answer will be between these two numbers.

10p-2(3p-6)=4(3p-6)-8p
lisabon 2012 [21]

Answer:

undefined / no solution

Step-by-step explanation:

10p - 2(3p-6) = 4(3p-6) - 8p

10p - 6p - 12 = 12p - 24 - 8p

4p - 12 = 4p - 24

0 = -12

0 cannot equal -12

4. (03.03 HC)
Kitty [74]

Answer:

A. yes, the data represents a function because u have no repeating x values. A function cannot have repeating x values...they can have repeating y values, just not the x ones

Step-by-step explanation:

B. table : (8,8)(12,12)(14,16)(16,16)

               look at ur points...when x = 8, y = 8...so the table, when x = 8 has a

               value of 8

relation : f(x) = 8x - 5....when x = 8

             f(8) = 8(8) - 5

             f(8) = 64 - 5

             f(8) = 59....and the relation has a value of 59

Therefore, the relation has a greater value when x = 8 <==

C. f(x) = 8x - 5...when f(x) = 19

    19 = 8x - 5

     19 + 5 = 8x

    24 = 8x

    24/8 = x

    3 = x <==
