Answer:
A
Step-by-step explanation:
Dimension of the rectangular fence:
Length = 30 ft
Width = 25 ft
Perimeter of the rectangular fence = 2(L + W)
= 2(30 + 25) = 2(55)
Perimeter = 110 ft
Fencing cost per foot = $4.05
Fencing cost for 110 ft = 110 × 4.05 = $445.50
Answer:
x+85 + x+105 = 180
x = -5
x+85 = -5+85 = 80
x+105 = -5+105 = 100
Step-by-step explanation:
The two angles form a straight line so they add to 180
x+85 + x+105 = 180
Combine like terms
2x + 190 = 180
Subtract 190 from each side
2x+190-190 = 180-190
2x = -10
Divide by 2
2x/2 = -10/2
x = -5
x+85 = -5+85 = 80
x+105 = -5+105 = 100
For #3 Nelson scored 29, because Craig scored 12 and Marla scored twice as craig, which was 24. After that we found out that she has 5 fewer than Nelson, witch would be plus 5.
If 1/3 of the oranges were spoiled and you threw away 4 oranges, there would be a total of 12 oranges.
4 x 3 = 12
If 1/4 of the grapefruits were spoiled and you threw away 7 grapefruits, there would be a total of 28 grapefruits.
7 x 4 = 28
Add the total amount of oranges to the total amount of grapefruits and you get how many pieces of fruit were in the basket.
12 + 28 = 40
Kinetic Energy = (1/2)mv².
where m = mass in kg= 2.5 * 10⁵kg = 250000 kg, v = velocity in m/s = 3*10² m/s = 300 m/s
Kinetic Energy = (1/2)*250000*300² = 0.5 * 250000 * 300 * 300
= 1.125 × 10¹⁰ Joules.
2) Relationship between aⁿ and a⁻ⁿ
a⁻ⁿ = 1 / aⁿ
or
aⁿ = 1 / a⁻ⁿ
