I believe its 12 since you cut 4 pieces into 3rds and 4x3=12

Since we have 4 pieces which we are "cutting into thirds," we can multiply the 4 by 3. This gives us an answer of 12 total pieces. This is because we are increasing the number of pieces we have due to cutting our existing pieces.

However, we could also solve this problem using the diagram that is included. If we were to draw lines to show each piece being cut into thirds, we would want to draw lines that separate each piece into three equal parts.

Now, we can use this diagram we just made by adding lines to determine the number of pieces we now have. Since each piece has now become 3 pieces, and there were 4 total pieces to being with, we have 12 total pieces.

The 200th term of the arithmetic progression 10 97,94,91,.............is

azamat

Answer:

-500

Step-by-step explanation:

Given sequence;

97, 94, 91 ......

Unknown;

The 200th term of the sequence;

Solution:

Since we were given an arithmetic progression, we need to first find the common difference;

Common difference = second term - first term

= 94 - 97

= -3

To find the 200th term, we use the expression below;

Sn = a + (n-1)d

a is the first term

n is the nth term

d is the common difference

S₂₀₀ = 97 + (200 - 1 ) x -3 = -500

An office supply store sells 12 rolls of tape for $29.88. At that rate, which proportion could be used to solve for c, the cost

kobusy [5.1K]

Answer:

$89.64

Step-by-step explanation:

First, you want to find your unit rate.

To do that, simply just divide what you know (cost/amount):

29.88/12

= 2.49

This means that one role of tape costs $2.49.

Now that we know that, you can simply just solve for value "c":

c = 2.49(36)

c = 89.64

3x²-24x + 12 What’s the factor of

Tems11 [23]

Answer:

[x - (4 + 2√3)] and [x - (4 - 2√3)]

Step-by-step explanation:

Given :

3x² - 24x + 12

Divide throughout by 3 to simplify :

1/3 x (3x² - 24x + 12)
x² - 8x + 4

Using the Quadratic Formula :

x = -b ± √b² - 4ac / 2a
x = -(-8) ± √(-8)² - 4(1)(4) / 2(1)
x = 8 ± √64 - 16 / 2
x = 8 ± √48 / 2
x = 8 ± 4√3 / 2
x = 4 ± 2√3

Factors are :

[x - (4 + 2√3)] and [x - (4 - 2√3)]

Distance between (-1,-3) and (-9,2)

Lisa [10]

The formula of a distance between two points:

$d=\sqrt{(x_2-x_1)^2+(y_2-y_1)^2}$

We have the points (-1, -3) and (-9, 2). Substitute:

$d=\sqrt{(-9-(-1))^2+(2-(-3))^2}=\sqrt{(-8)^2+5^2}=\sqrt{64+25}=\sqrt{89}$

<h3>Answer: d = √89</h3>
