Answer:

If you are talking about common factors, the common factors of 15 are 15, 5, 3, and 1. The common factors of 45 are 45, 9, 5, 3, and 1. Common factors are numbers that a number can be divided by. Like 35 / 5, 5 is a common factor of 35.

Step-by-step explanation:

John is 1 8 meter shorter than Paul, and Paul is 0.25 meter taller than Andrew. If John’s height is 1 3 4 meters, what is Andrew

9966 [12]

Answer:

Andrew's height is $1\frac{5}{8}$ meters

Explanation:

We know that John's height is $1\frac{3}{4}$ meters

We are given that:

John is $\frac{1}{8}$ meters shorter than Paul

This means that:

Paul's height = John's height + $\frac{1}{8}$

Paul's height = $1\frac{3}{4} + \frac{1}{8} = 1\frac{7}{8}$ meter

We are given that:

Paul is 0.25 meters taller than Andrew

This means that:

Andrew's height = Paul's height - 0.25

Andrew's height = $1\frac{7}{8} - 0.25 = 1\frac{5}{8}$ meters

Hope this helps :)

Find the measure of CDE

Free_Kalibri [48]

Step-by-step explanation:

Here,

CDE+27+103+50+35=360(BEING THE SUM OF PIE CHART

CDE+215=360

CDE=360-215

CDE=145

I got the first two can you help me with the last one PLZ

1. Geometric Sequence

2. $a_n = a_{n-1} * 3$

3. $a_n = 6 * (3)^{n-1}$

Step-by-step explanation:

Given sequence is:

6, 18, 54, 162,....

Here

$a_1 =6\\a_2 = 18\\a_3 = 54$

(a) Is this an arithmetic or geometric sequence?

We can see that the difference between the terms is not same so it cannot be an arithmetic sequence.

We have to check for common ratio (ratio between consecutive terms of a sequence) denoted by r

$r = \frac{a_2}{a_1} = \frac{18}{6}= 3\\r = \frac{a_3}{a_2} = \frac{54}{18} = 3$

As the common ratio is same, the given sequence is a geometric sequence.

(b) How can you find the next number in the sequence?

Recursive formulas are used to find the next number in sequence using previous term

Recursive formula for a geometric sequence is given by:

$a_n = a_{n-1} * r$

In case of given sequence,

$a_n = a_{n-1} * 3$

So to find the 5th term

$a_5 = a_4*3\\a_5 = 162*3\\a_5 = 486$

(c) Give the rule you would use to find the 20th week.

In order to find the pushups for 20th week, explicit formul for sequence will be used.

The general form of explicit formula is given by:

$a_n = a_1 * r^{n-1}$

Putting the values of a_1 and r

$a_n = 6 * (3)^{n-1}$

Hence,

1. Geometric Sequence

2. $a_n = a_{n-1} * 3$

3. $a_n = 6 * (3)^{n-1}$

The Percent of increase

ANEK [815]

Percent of Increase = Increase / Original * 100%

Increase = $33 - $30 = $3
Original Price = $30

Percent Increase = $3 / $30 * 100% ==== 10%
