ricky found a beetle that has a body one fourth the length of the fraction strips used in problem 1.2. how many beetle. how many beetle bodies placed end to end would have a total length equal to the length of a fraction strip. ricky drew 13 paper beetle bodies end to end each the same length as the one found. how many fraction strips long is ricky line of beetle bodies.

Answers


1/4 of 1/4

= 1/8

13 x 1/8

= 13/1 x 1/8

= 1 5/8

therefore there are 1 and 5/8 in the line of rickys fraction strips.

on a fraction strip line this is 13/8

Which choice is the appropriate simplified form and restriction for the variable 2x-3x^2/5x^3a. 1/5

b. 1/5x, (x=0)

c 1/5x^2, (x=0)

d. 2-3x/5x^2, (x=0)

by the way all of the zeros have an slash through them which I couldn't figure out how to type. Could someone please please please help me?

Answers

If you would like to find the simplified form, you can do this using the following steps:

(2x - 3x^2) / (5x^3) = (x(2 - 3x)) / (x(5x^2)) = (2 - 3x) / (5x^2) if x != 0

The correct result would be (2 - 3x) / (5x^2) if x != 0.

Nine is 4% of what number

Answers

Let's call the number we are looking for x

9 = 4% * x

9 = 4/100 * x

9 = 0.04 * x

x = 9/0.04

x = 225

Nine is 4% of 225.

Find the domain and range, and compare it with the function y=1/x

Answers

f(x) = 1/x and g(x) = -10/x

Domain:  same:  all real numbers other than x=0.
Range:  strictly speaking, these 2 functions have the same range:  all real numbers other than y=0.  But the graph of g(x) = -10/x looks stretched vertically when compared with that of f(x) = 1/x.
