If you wanted to find the difference of 6/25 - 4/5, what common denominator should you choose? Why?

Answers

Answer:

Choose 1/25 as the common denominator

Step-by-step explanation:

1/25 is the lowest number that both existing denominators can be factored into.

6/25 would remain the same....  6/25

4/5 would become 20/25.....  multiply the top and bottom by 5

So 6/25 - 20/25 = - 14/25

16. A craft shop sold 150 pillows. Small pillows were $6.50 each and large pillows were $9.00 each. If the total amount collected from the sale of these items was $1180.00, what is the total number of each size pillow that was
sold?

Answers

Answer:

82 large pillows, 68 small pillows

Step-by-step explanation:

Suppose all pillows sold were small pillows:

150×$6.50=$975

$1180-$975=$205

$9-$6.50=$2.50

$205÷$2.50=82 (no of large pillows sold)

No. of small pillows sold

=150-82

=68

Find the length of x of the side of the larger triangle. (Assume that the two triangles are similar, and use the fact that corresponding sides of similar triangles are proportional)
X=

Answers

Similar triangles may or may not be congruent

The value of x that makes both triangles similar is 4.5

The equivalent ratio of both triangles is:

[tex]\mathbf{2 : 1 = 9 : x}[/tex]

Express the above equivalent ratio as a fraction

[tex]\mathbf{\frac 12= \frac x9 }[/tex]

Multiply both sides of the fraction by 9

[tex]\mathbf{\frac 12\times 9 = \frac x9 \times 9 }[/tex]

Cancel out common factors

[tex]\mathbf{\frac 12\times 9 = x}[/tex]

Divide 12 by 9

[tex]\mathbf{4.5 = x}[/tex]

Rewrite the above expression as:

[tex]\mathbf{x = 4.5 }[/tex]

Hence, the value of x is 4.5

Use the IQR to determine if any of the data in the data set are outliers.

{23,80,43,23,0,20,23,23,20,28}

Answers

Using the IQR, the only outlier in the data set is: 0.

What is the IQR of a Data Set?

IQR = upper quartile (Q3) - lower quartile (Q1).

Given the data set, 23,80,43,23,0,20,23,23,20,28:

Quartile (Q1): 20

Quartile (Q3): 31.75

IQR = 31.75 - 20 = 11.75

The outliers are data values that lie below:

Q1  - (1.5 × IQR) = 20 - (1.5 × 11.75) = 2.375

And data values that are above:

Q3 + (1.5 × IQR) = 31.75 + (1.5 × 11.75) = 49.375

Therefore, the only outlier is: 0.

On the contrary, it was he who had advocated it in the beginning, and the plan which Snowball had drawn on the floor of the incubator shed had actually been stolen from among Napoleon's papers. The windmill was, in fact, Napoleon's own creation. Why, then, asked somebody, had he spoken so strongly against it? Here Squealer looked very sly. That, he said, was Comrade Napoleon's cunning. He had seemed to oppose the windmill, simply as a maneuver to get rid of Snowball, who was a dangerous character and a bad influence. Now that Snowball was out of the way, the plan could go forward without his interference. This, said Squealer, was something called tactics. He repeated a number of times, "Tactics, comrades, tactics!" skipping round and whisking his tail with a merry laugh. The animals were not certain what the word meant, but Squealer spoke so persuasively, and the three dogs who happened to be with him growled so threateningly, that they accepted his explanation without further questions.Which figure from Russian history does Napoleon most likely represent?
