<h3>Answer: Choice B</h3>
==================================================
Explanation:
Using your calculator, you should find that
- sqrt(125) = 11.1803 approximately
- sqrt(196) = 14 exactly
- sqrt(207) = 14.387 approximately
- sqrt(220) = 14.832 approximately
Each approximate result has its decimal digits go on forever without any pattern. So we cannot write those values as a fraction of two integers. The decimal expansion must have some kind of pattern that repeats forever, so we could consider it rational.
Only choice B results in a whole number. The value 14 is the same as 14/1, showing it can be written as a fraction of two integers. Therefore choice B is rational.
Answer:
f = 108
Step-by-step explanation:
p = f/a [p = 27 and a =4]
27 = f/4 [multiply 27 and 4 to get 108]
check your work: 108/4 = 27
8x-8...............I think so if it’s distributed
Answer:
The weight of the enlarged paperweight is
Step-by-step explanation:
we know that
If two figures are similar, then the ratio of its volumes (or its weights) is equal to the scale factor elevated to the cube
Let
z-----> the scale factor
x ----> the enlarged paperweight weight
y ----> the original paperweight weight
we have
substitute and solve for x
