Answer:
<u>109.26: </u>decimal
<u>5469/50: </u>reduced fraction
140 is 120% of what number? <u>116.67</u>
What percent of the production is defective? <u>0.6%</u>
Step-by-step explanation:
For the first one, we know that 1214 is 100%, so we apply the rule of three to find 9% of the sample:
Now, to find the reduced fraction we operate with the decimal and then we reduce the resulting fraction:
For the second exercise we proceed, again, with the rule of three:
For the third question, we will apply the rule of three again:

Step-by-step explanation:
Each year, the car's value decreases by 19%. 14,650 times 0.19 is $2783.50, meaning that his car loses $2783.50 in value per year. The chart values are:
1. $11,866.50
2. $9083
3. $6299.50
4. $3516
As for B, the equation would be $14,650 - $2783.50y
Answer:
SAS
Step-by-step explanation:
we know 2 pairs of sides (fl=ly, wl=lw) are congruent. we know one angle is congruent. thus we can tell congruency.
Answer:
=45x√5x
Step-by-step explanation:
The provided expression is: 3√5x×3√25x²
We can simplify 3√25x² because √25x²=5x
3×5x=15x
Combine with the rest of the expression through multiplication.
3√5x×15x
=45x√5x
The expression 3√5x×3√25x² is equivalent to 45x√5x.
The expected simplified answer is 45x√5x
