10. A bell rings every 25 minutes while another bell rings every 40 minutes. If the bells rang together at 6 A.M., at what time
Ivahew [28]

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!!

Answer:

x= 1/2

and y=3

Step-by-step explanation:

Let's solve your system by substitution.

y=10x−2;2x+y=4

Step: Solvey=10x−2for y:

y=10x−2

Step: Substitute10x−2foryin2x+y=4:

2x+y=4

2x+10x−2=4

12x−2=4(Simplify both sides of the equation)

12x−2+2=4+2(Add 2 to both sides)

12x=6

12x

12

=

6

12

(Divide both sides by 12)

x=

1

2

Step: Substitute

1

2

forxiny=10x−2:

y=10x−2

y=10(

1

2

)−2

y=3(Simplify both sides of the equation)

Answer:

x= 1 /2

and y

The histogram shows the number of miles driven by a sample of automobiles in New York City. What is the maximum possible number
hjlf

Answer:

The maximum possible number of miles traveled by an automobile included in the histogram is 40,000 miles.

Step-by-step explanation:

A histogram is a bar graph reprinting the frequency of various categories.

In a histogram the <em>y</em>-axis represents the frequency and the <em>x</em>-axis represents the categories.

Consider the histogram provided for the number of miles driven by a sample of automobiles in New York City.

The <em>y</em>-axis represents the frequency and the <em>x</em>-axis represents the number of miles driven.

The category 10,000 miles has the highest frequency at 30.

And the maximum possible number of miles traveled by an automobile is 40,000 miles.

Thus, the maximum possible number of miles traveled by an automobile included in the histogram is 40,000 miles.
