What are the common factors for 88 and 24
Zinaida [17]
To find the common factors between two numbers, you must first break the numbers down into factors, and then find all common factors.
Let's break down 88.

88: 2 x 44, 4 x 22, 8 x 11.

Now let's break down 24.

24: 2 x 12, 3 x 8, 4 x 6.

Now that we've factored both numbers, let's select all the common factors.

Common factors:
1, 2, 4, 8.

A particular geometric sequence has strictly decreasing terms. After the first term, each successive term is calculated by multi
Maksim231197 [3]

Answer:

6 possible integers

Step-by-step explanation:

Given

A decreasing geometric sequence

Ratio = \frac{m}{7}

Required

Determine the possible integer values of m

Assume the first term of the sequence to be positive integer x;

The next sequence will be x *  \frac{m}{7}

The next will be; x *  (\frac{m}{7})^2

The nth term will be x *  (\frac{m}{7})^{n-1}

For each of the successive terms to be less than the previous term;

then \frac{m}{7} must be a proper fraction;

This implies that:

0 < m < 7

<em>Where 7 is the denominator</em>

<em>The sets of </em>0 < m < 7<em> is </em>\{1,2,3,4,5,6\}<em> and their are 6 items in this set</em>

<em>Hence, there are 6 possible integer</em>

Math help please? There are 12 more toy cars than toy trucks in a box with a total of 38 toy cars and toy trucks. How many toy t
dlinn [17]
Let, the number of toy trucks = x
Then, number of toy cars = (x + 12)

Now, we have: x + x+12 = 38
2x + 12 = 38
2x = 38 - 12
2x = 26
x = 26/2
x = 13

So, there are 13 toy trucks in total.

Hope this helps!
