Answer:
Step-by-step explanation:
3.8 is 2x 3.8/2 is 1.9
For the mean you add them all up and divide by the ammount of numbers you added. So it would be 118
Just subtract 2.003 and 0.520 which gives you 1.483 so there is 1.483 kilogram of soil remaining hope this helps!
Answer:
m<PTR = 140°
Step-by-step explanation:
First, find the value of x. To find the value of x, derive an equation which you'd use in solving for x.
m<PTQ = (x + 28)°
m<RTS = (2x + 16)°
m<PTQ = m<RTS (vertical opposite angles are congruent)
Therefore:
x + 28 = 2x + 16
Solve for x. Combine like terms
28 - 16 = 2x - x
12 = x
x = 12
Find m<PTQ
m<PTQ = (x + 28)
plug in the value of x
m<PTQ = 12 + 28 = 40°
m<PTR + m<PTQ = 180° (supplementary angles)
m<PTR + 40° = 180° (substitution)
m<PTR = 180 - 40 (subtracting 40 from each side)
m<PTR = 140°

Step-by-step explanation:
y=5(2)ˣ
y=5(2)⁻²=5(1/2²)=5(1/4)=5/4
y=5(2)⁻¹=5(1/2¹)=5(1/2)=5/2
y=5(2)⁰=5(1)=5
y=5(2)¹=5(2)=10
y=5(2)²=5(4)=20
