What is the smallest number that can be subtracted from 376234 to make it divisible by 11

Answers

Answer 1

Answer:

Answer:

Odd:: 8+7+9=24

Even:: 2+8=10

So difference of odd and even is 24-10=14

Reducing 3 from this will make the difference (14–3) divisible by 11.

So the number to be subtracted is 3

And the number is 82786.

Step-by-step explanation:

Answer 2

Answer:

Answer:

Step-by-step explanation:

If you subtract the number by 1 i.e. 376233 it will be exactly divisible by 11.

An object launched vertically from a point that is 37.5 feet above ground level with an initial velocity of 48.6 feet per second can be represented by the equation h=−16t^2+48.6t+37.5, where h is the height of the object and t is the time after the object is launched. How long does it take the object to hit the ground?

Answers

Answer: 3.675 seconds

Step-by-step explanation:

Hi, when the object hits the ground, h=0:

h=−16t^2+48.6t+37.5

0=−16t^2+48.6t+37.5

We have to apply the quadratic formula:

For: ax2+ bx + c

x =[ -b ± √b²-4ac] /2a

Replacing with the values given:

a=-16 ; b=48.6; c=37.5

x =[ -(48.6) ± √(-48.6)²-4(-16)37.5] /2(-16)

x = [ -48.6 ± √ 4,761.96] /-32

x = [ -48.6 ± 69] /-32

Positive:

x = [ -48.6 + 69] /-32 = -0.6375

Negative:

x = [ -48.6 - 69] /-32 = 3.675 seconds (seconds can't be negative)

Feel free to ask for more if needed or if you did not understand something.

Last week at best bargain, 75% of computers sold were laptops. If 340 computer were sold there last week, how many laptops were sold?

Answers

Total number of computers sold last week from Best Bargain = 340
Percentage of laptops sold last week from Best Bargain = 75%
These are the information's that we can find given in the question. Based on these information's the answer to the question can be easily found.
Number of laptops sold from Best Bargain last week = 340 * (75/100)
   = 340 * (3/4)
      = 85 * 3
   = 255
So out of the total of 340 computers sold from Best Bargain last week, 255 were laptops. I hope this is the answer you were looking for.

What is the probability of choosing a card that does not have a digit 1 on it? Give the answer as a fraction numbers: 1,2,3,4,5,6,7,8,9,10

Answers

Final answer:

The probability of selecting a number, from the set {1,2,3,4,5,6,7,8,9,10}, that does not have the digit '1' on it, is 9 out of 10, or 9/10. Each selection is an independent event.

Explanation:

The subject of this question is Probability, a branch of Mathematics. Given the numbers 1,2,3,4,5,6,7,8,9,10, we have ten numbers in total, and only one of these numbers (1) is what we're trying to avoid. Hence, the probability of choosing a number that does not have the digit 1 on it is 9 (total numbers) - 1 (digit 1) divided by 10 total numbers, giving us a final answer of 9/10.

Probability can be represented as a fraction, where the numerator represents the favorable outcomes and the denominator represents the total number of outcomes.

Choosing each individual number is an independent event, meaning the outcome of each selection does not affect the probability of the subsequent selection.
