<h3>
Answer: Comelia is correct</h3>
====================================================
Explanation:
We're told that "Christopher says that all Rational (Q) numbers are Whole (W)", which makes Christopher not correct. Some rational numbers are whole numbers. For instance, the number 7 = 7/1 is rational and it's a whole number as well.
However something like 1/2 is rational, but it's not a whole number. A whole number doesn't have any fractional or decimal part to it. It can be thought of the number of something.
Comelia is correct because all whole numbers are rational. If x is some whole number, then x = x/1 is rational as well. Replace x with any whole number you want. Her statement does not work in reverse as shown above.
When drawing a Venn diagram, the circle for "whole numbers" will be entirely inside the circle for "rational numbers", and not the other way around.
When the dilation of a line or is centered at the origin,
both the x and y coordinates are multiplied by the same value, k (which
represents the scale or ratio of dilation)
If ab is dilated by a factor of 2/5 to produce a’b’, then k
= 2/5
Since the dilation is centered at origin,
The y-coordinate of b' what will be 2/5 of the y-coordinate of b.
Answer:
128.7
Step-by-step explanation:
81.90 ÷ 7 = 11.7
11.7 x 11 = 128.7
Answer:
Step-by-step explanation:
None of your proposed answers has an exponent <em>t</em>.
Here's the logic behind the answer:
Year 0: pop. = 2500
Year 1: pop. = 2500(1.04) That is 104% of the previous year's pop.
Year 2: pop. = 2500(1.04)(1.04) = 2500(1.04)^2
Year 3: pop. = 2500(1.04)^2 x (1.04) = 2500(1.04)^3
See the pattern? The exponent matches the year number.
