The answer is C because Which of the following equations is equivalent to 1/2x-2/3y= c I'd just 6 times as much, so 1/2 times 6 equals 3 and 2/3 times 6 is 4
Answer:
the scale factor k is between 0 and 1
Step-by-step explanation:
A dilation is a transformation that produces an image that is the same shape as the original, but is a different size.
A dilation with the larger image than initial figure is called an enlargement.
A dilation that the smaller image than initial figure is called a reduction.
- If the scale factor k is greater than 1, the image is an enlargement
- If the scale factor k is between 0 and 1, the image is a reduction
- If the scale factor k = 1, the figure and the image are congruent
Thus, if the image is smaller than the original figure, then the scale factor k is between 0 and 1.
Given that the rate of Uranium decay is 57%, this means that after each day, only 0.43 of the mass from the prior day is left. The equation that would best represent the scenario is,
a(t) = a₁(0.43^t)
where a(t) is the mass after t days and t is the number of days. Substituting,
a(t) = 3,280(0.43^15)
= 0.01 lbs.
S = a*b this is formula for surface.
Condition of the task is:
a:b = 1.6:1
a = 1.6*b
Now we implement this in surface formula
S = 1.6*b^2
and calculate "b"
b = 40
a = 1.6*40 = 64
Answer is B.
