7 Cassie wants to determine the length of the shadow that a 20-foot tall telephone pole casts without measuring it. If Cassie's

Sophie [7]

Answer:

10 ft

Step-by-step explanation:

In order to solve this question, we need to set up a proportion:

$\frac{\textrm{Height of mailbox}}{\textrm{Length of shadow}} = \frac{\textrm{Height of telephone pole}}{\textrm{Length of shadow}}$

Replacing with actual values:

$\frac{45 \textrm{ in}}{22.5 \textrm{ in}} = \frac{20 \textrm{ ft}}{x \textrm{ ft}}$

Cross-multiplying:

$45\times{x} = 20\times{22.5}\\45x = 450$

Dividing both sides by 45:

$\frac{45x}{45} = \frac{450}{45}\\\\x = 10$

Therefore, the length of the telephone pole's shadow is 10 ft.

The set of numbers in the Collatz Conjecture are 1, 4, 2, 1, 4, 2, 1, 4, 2....

<h3>How to generate the numbers in the Collatz Conjecture</h3>

To start with, we make use of the following starting point:

Starting point = 1

The rule is given as:

If the last number is odd, multiply it by 3 and add 1.
If the last number is even, divide the number by 2.

1 is an odd number.

So, we use the first rule and, we have:

1 * 3 + 1 = 4

4 is an even number.

So, we use the second rule and, we have:

4/2 = 2

So, the first three numbers in the Collatz Conjecture are:

1, 4, 2

Using the given rules, we have:

1, 4, 2, 1, 4, 2, 1, 4, 2....

The above means that there is only one set of repeating numbers in the Collatz Conjecture.

Hence, the set of numbers in the Collatz Conjecture are 1, 4, 2, 1, 4, 2, 1, 4, 2....

What fraction of the whole is 3%4 × 2/3

Alex777 [14]

Answer:

<em>The given operation represents half the whole</em>

Step-by-step explanation:

<u>Fractions </u>

They represent rational numbers of the form

$\displaystyle \frac{a}{b}$

where a and b are integer numbers and b is not zero

Fractions can also be used as ratios to compare quantities. For example, if a>b, then the fraction a/b is greater than 1. In the case of a<b, it's interpreted as parts of a whole.

The fraction

$\displaystyle \frac{2}{5}$

means something has 2 of each 5 parts of the whole.

The question requires to find the product of

$\displaystyle \frac{3}{4}\times \frac{2}{3}$

$\displaystyle \frac{2}{4}=\frac{1}{2}$

Thus, the given operation represents half the whole
