if a clock strikes the appropriate number of time on each hour. how many times will it strikes in one day?
Keith_Richards [23]

Strike is the way that the noise made on the hour it’s described. Each hour corresponds to a specific strike, 1 has 1 strike, 2 have 2 strikes, 3 have 3 strikes, and so on.

The solution would be like this for this specific problem:

1 + 2 +3 + 4 + 5 + 6 + 7 + 8 + 9 + 10 + 11 + 12 = 78 strikes for a 12 hours

78 * 2 = 156 (since a day has 24 hours)

So it will strike 156 times per day. I am hoping that this answer has satisfied your query and it will be able to help you in your endeavor, and if you would like, feel free to ask another question.

Lia wants to estimate 4 1/7 x 3 3/5 To estimate, she simplifies the expression 4 x 3 1/2 .
Temka [501]
Given:
4 1/7 * 3 3/5

4 1/7 = (4*7)+1/7 = 29/7
3 3/5 = (3*5)+3/5 = 18/5

29/7 * 18/5 = 29 * 18 / 7 * 5 = 522 / 35 = 14.91

Simplified expression.
4 x 3 1/2

3 1/2 = (3*2)+1/2 = 7/2

4 * 7/2 = 4*7 / 2 = 28 / 2 = 14

It is a close estimate.   Actual: 14.91 vs Estimate: 14

NEED HELP WILL GIVE 5 STAR, THANKS, AND BRAINLIEST FOR BEST ANSWER PLEASE HELP ~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~
yulyashka [42]

Answer:

h = -t+20

After 8 hours the candle will be 12 inches

Step-by-step explanation:

We have 2 points (time, inches)

 (3,17)  and (5,15)

We can find the slope

m = (y2-y1)/(x2-x1)

   = (15-17)/(5-3)

   = -2/2

   = -1

We can use point slope form

y-y1 = m(x-x1)

Replace y with h and x with t

h-17 = -1 (t-3)

Distribute

h-17 = -t+3

Add 17 to each side

h-17+17 = -t+3+17

h = -t+20

After 8 hours

h = -t+20

h = -8+20

h= 12
