Answer: 6 ft - 2 in
Step-by-step explanation: To convert ft into inches, multiply the amount of ft by 12.
6 * 12 = 72
72 in - 2 in
To find a the scale, make a ratio
72:2
This scale can also be made into 36:1 and 144:4 by simplifying
The error is in <em>Step-4</em>.
A negative exponent does NOT mean that the number turns negative. A negative exponent means the number is in the denominator.
(4)⁻⁴ means (1/4⁴) . That's (1/256) . All positive numbers.

a.20 minutes
b.3 tasks
Step-by-step explanation:
60 divided by 3 = 20
Answer:
B. y - 35 = 2(x - 10)
Step-by-step explanation:
The height of the plant, y, after x days could be modeled by the equation
<h3>y-y0=k(x-xo) (1)
,</h3><h3>
where y0 was the initial height at 'x0'th. day, and k is the constant of proportionality.</h3><h3>
From equation (1), k could be evaluated as follows:</h3><h3>
k=(y-y0)/(x-x0) </h3><h3>
From the problem statement, we may determine k by plugging in the given values, e.g. y0= 35, x0=10, y=55, x=20.</h3><h3>
Thus,</h3><h3>
k=(55-35)/(20-10)=2</h3><h3>
Therefore, the model equation becomes</h3><h3>
y-35=2(x-10)</h3><h3>
