One of the basic equations in physics is Speed = Distance/Time. Thus,

Distance = Speed*Time

Time = 1 light-year * 365 days/yr * 24 h/day * 3,600 s/h = 31536000 seconds
Distance = (3×10⁸ m/s)*(31536000 s) = 9.4608×10¹⁵ meters

Convert meters to miles:
Distance = 9.4608×10¹⁵ m * 1 mile/1,609 m = 5.88×10¹² miles

Angle 1 is vertical to Angle 2. Angle 1 =94, Angle 2 = 2(x-13), Find the value of x.
rodikova [14]

Answer:

x= 56

Step-by-step explanation:

86+94= 180 which if supplementary angles have to equal 180°

I don't know if you can tell but what's in red means distribute

then I added 26 on both sides with like terms

on the left side 86+26=112 and right side is left with 2x

then divide both sides by 2 to leave x by itself

112/2= 56 and 2x/2=x

so 56=x

PETS Becky wants to buy some fish for her aquarium. She has $20 to spend and the fish cost $2.50 each. Write and solve an inequa
Vilka [71]
To start, you want to determine the inequality. You can do this by setting the number of buying n fish to be less than or equal to her current amount of money, being as it can't go over or she wouldn't be able to afford the fish. This inequality would be written so her amount of money (20) would be greater than or equal to the cost of n fish (2.5n), which would then look as such: 20≥2.5n. To solve this inequality, just solve for n by dividing both sides by 2.5, giving you 8≥n. This would mean that Becky can afford to buy up to 8 fish.
