Answer:
2 hours and 48 minutes
Step-by-step explanation:
Time = Distance/Speed
= 84/30
= 2.8 hours
To convert 2.8 hours into hours and minutes, 2.8*60 = 168 minutes. Therefore the time taken to travel 84miles is 2 hours and 48 minutes
Answer:
c. C(x) = 88 - 1.75x
Step-by-step explanation:
Let's represent this with an equation. We know that the total number of burgers is 32, and the number of Whoppie Jr. is x, so the number of Whoppie is 32-x.
Each Whoppie costs 2.75, and each Whoppie Jr. costs 1, so multiply the cost by the number to get the equation:
C(x) = 1x + 2.75(32-x)
Now distribute and simplify.
C(x) = 2.75*32 + 1x -2.75x
<u>C(x) = 88 -1.75x</u>
Answer:
λ = 1.3252 x 10⁻⁴
Step-by-step explanation:
Since we are already given the half-life, the decay expression can be simplified as:
For a half-life of t =5230 years:
The decay-rate parameter λ for C-14 is 1.3252 x 10⁻⁴
Answer: thanks
Step-by-step explanation:
Answer:
Slope = -4
Y-intercept = 0
Step-by-step explanation:
the equation of the line is written in slope-intercept form: y = mx + b where m = slope and b = y-intercept
To find the slope, look at the number before x.
And for y-intercept, take a look at the number at last
(If there isn’t no y-intercept, that indicates that the y-intercept is 0)
Hope this helps!
Love you.
