The average person lives 78 years Does the average person live for at least 1,000,000 hours?

Answers

First we will divide to see how many years will come in the amount of days,

1,000,000 ÷ 365 ≈ 2,740

SO, in 1,000,000 days there are ABOUT 2,740 years. 

Next we will multiply  to see how many days there are in 78 years.

365 × 78 =  28,470

SO, there are 28,470 days in 78 years. 

No, the average person lives more than 1,000,000 days. 

Hope I helped ya!! 

I just answered this fore someone, a couple of days ago! 
No the average person lives longer.
60 x 24 = 1,440
1,140 x 365 = 525,600
525,600 x 78 = 40,996,800
Which is more than 1,00,000

The sum of the roots of 8x^2- 2x

Answers

Answer:

1/4

Step-by-step explanation:

To find the roots of the expression, factor the expression by GCF.

8x^2 - 2x\n2x(4x-1)

The roots are the factors set equal to 0 and solved for x.

2x = 0

x=0

4x-1 = 0

x = 1/4

The sum is the addition of the two roots 0 + 1/4 = 1/4

-3(-5v-u+6)

Answers

Hey there!

-3(-5v - u + 6)

= -3(-5v) - 3(-u) - 3(6)

= 15v - 3u - 18

= 3u + 15v - 18

Therefore, your answer is: 3u + 15v - 18

Good luck on your assignment and enjoy your day!

~Amphitrite1040:)
I could be wrong however, I'm sure it's: -3x-5= 15v (two negatives become a positive. -3-u becomes 3u. (Two negatives also become a positive), and -3+6 is -3x6= -18. Hence, the answer is: 15v+3u-18.
