Answer: I think the answer is B
Step-By-Step Explination:
First you find out what x is by doing 42 multiplying it by 0.1 witch equals 4.2 gallons per mile
Next you figure out what y is by doing 4.2y (witch is 4.2 times y)
Answer:
the fist one

Answer:
M = 1/0.000121 = 8264.5 years
Step-by-step explanation:
M = − k ∫∞₀ teᵏᵗdt
To obtain this mean life, we'll use integration by parts to integrate the function ∫ teᵏᵗdt
∫udv = uv - ∫ vdu
u = t
du/dt = 1
du = dt
∫ dv = ∫ eᵏᵗdt
v = eᵏᵗ/k
∫udv = ∫ teᵏᵗdt
uv = teᵏᵗ/k
∫ vdu = eᵏᵗ/k
∫ teᵏᵗdt = (teᵏᵗ/k) - ∫eᵏᵗ/k
But, ∫eᵏᵗ/k = (1/k) ∫eᵏᵗ = (1/k²) eᵏᵗ = eᵏᵗ/k²
∫ teᵏᵗdt = (teᵏᵗ/k) - eᵏᵗ/k²

Answer:
<h2><em><u>
t = 15.2 is the answer</u></em></h2>
Step-by-step explanation:
<h2><em><u>
1. Make an equation</u></em></h2>
numbers to find perimeter = perimeter
Side + Side + 2 unknown sides = perimeter
12 + 7.8 + 2t = 50.2
<h2><em><u>
2. Simplify like terms</u></em></h2>
19.8 + 2t = 50.2
<h2><em><u>
3. Solve</u></em></h2>
19.8 + 2t = 50.2
-19.8 - 19.8
2t = 30.4
<h2><em><u>
t = 15.2</u></em></h2>
<h2><u><em>
4. Check:</em></u></h2>
12 + 7.8 + t + t = 50.2
12 + 7.8 + (15.2) + (15.2) = 50.2
<h2><em><u>
50.2 = 50.2</u></em> Correct!</h2><h2 />
Hope this helped,
