Answer:
Proxima Centauri is 2.478 x 10¹³ miles from Sun.
Explanation:
Distance of Proxima Centauri to sun = 4.24 light years
1 light year = 5.9 x 10¹² miles.
Distance of Proxima Centauri to sun in miles = Distance in light years x 5.9 x 10¹² miles
So, Distance of Proxima Centauri to sun in miles = 4.2 x 5.9 x 10¹² miles
= 2.478 x 10¹³ miles
So Proxima Centauri is 2.478 x 10¹³ miles from Sun.
Do you see a pattern in the given information?
3 pages in 13 min
9 pages in 39 min
15 pages in 65 min
the rate of pages per min is constant
3/13 = 9/39 = 15/65
the Question is asking for time.. So the we need the rate as min per page 13/3 so when multiplied by the number of pages it cancels to give minutes.
Units cancel out just like numbers do so you know that the problem is set up correctly.
Answer:
4 1/2 days
Step-by-step explanation:
<u>cows | 6 | 9</u>

6 divided by 2 is 3
9 divided by 2 is 4.5
x = 4 1/2 days
Answer:
a
Step-by-step explanation:
Since the graph intersects the x-axis at 2 points, it has 2 solutions which means that the discriminant is greater than 0. The only option that satisfies this is 10.
Answer:
50 pockets
Step-by-step explanation:
Total yards of lace = 75
Yards to decorate one Pocket = 1 1/2 yards
How many pockets can she decorate with the lace
Number of pockets she can decorate with the lace = Total yards of lace / Yards to decorate one Pocket
= 75 ÷ 1 1/2
= 75 ÷ 3/2
= 75 × 2/3
= 150/3
= 50
Number of pockets she can decorate with the lace = 50 pockets
