Explanation:
____________________________________________
Given:
____________________________________________
10 years ago, # of illiterate people = 150 lakhs;
"Now" ; # of illiterate people = 100 lakhs ;
____________________________________________
So; the decrease in the # of illiterate people = "(150 - 100) = 50 lakhs ;
____________________________________________
To calculate the "percentage of decrease" :
____________________________________________
The "percentage of decrease" =
{"decrease in the # of illiterate people"} / {"# of illiterate people started with"] ;
× 100 (percent).
__________________________________________________
= [tex] \frac{50}{150} [/tex] * 100 % ;
{Note that: [tex] \frac{50}{150} [/tex] = [tex] \frac{5}{15}[/tex] ;
→ The "zeros" cancel out ;
→ [tex] \frac{50}{150} [/tex] * 100 % ;
= [tex] \frac{5}{15}[/tex] * 100 ;
Note: [tex] \frac{5}{15}[/tex] = [tex] \frac{(5/5)}{(15/5)} [/tex] ;
= [tex] \frac{1}{3} [/tex] ;
__________________________________________________
→ [tex] \frac{1}{3}[/tex] * 100 = [tex] \frac{1}{3}[/tex] * [tex] \frac{100}{1}[/tex] ;
_________________________________________________________
= [tex] \frac{(1*100)}{(3*1)} [/tex] % ;
= [tex] \frac{(100)}{(3)} [/tex] % ;
= "(100 ÷ 3) % ;
= " 33 ⅓ % " .

Answer: The percentage of decrease is: " 33 ⅓ %" .

Triangle ABC has vertices at A(−3, 4), B(4, −2), C(8, 3). The triangle is translated 4 units down and 3 units left. Which rule represents the translation? After the translation, what are the coordinates of vertex C?
Answers
Answer: Correct answer is (x, y) → ( x − 3, y − 4); (5, −1)
Step-by-step explanation: Starting from point 8,3 we go down 4 on the y-axis (y-4)and stopping at -1 then we go left on the x-axis (x-3) stopping at 5.
So the new coordinate for the vertex C should read 5,-1.
After the translation , the coordinates of vertex C are ( 5 , -1 )
Further explanationThere are several types of transformations:
TranslationReflectionRotationDilationLet us now tackle the problem!
This problem is about Translation.
The triangle is translated 4 units down and 3 units left.
The rule that represents the translation will be [tex]\left[\begin{array}{ccc}-3\\-4\end{array}\right][/tex]
Let's find the translation for every vertice of Triangle ABC:
A(-3 , 4) → A'(-3 + (-3) , 4 + (-4)) = A'(-6 , 0)
B(4 , -2) → B'(4 + (-3) , -2 + (-4)) = B'(1 , -6)
C(8 , 3) → C'(8 + (-3) , 3 + (-4)) = C'(5 , -1)
From the results above, we can illustrate the translation process as shown in the attached picture
Conclusion:After the translation , the coordinates of vertex C are ( 5 , -1 )

The original price of a watch was $550. During a mid year sale, the selling price was $440. Find the percent discount
Answers
$550 - $440 = $110
Next, you would need to create an equation for this problem. Let x represent the unknown percent discount.
[tex] \frac{110}{550} [/tex] = [tex] \frac{x}{100} [/tex]
Cross multiply.
550x = 11,000
Now, all you would need to do is isolate the x. To do this, you would divide both sides of the equal sign by 550.
x = 20
x = 20%
The percent discount was 20%.
I hope this helps!
Final answer:
The percent discount for the watch is 20%.
Explanation:
To find the percent discount on the watch, we first calculate the difference in price between the original price and the sale price.
Subtract the sale price ($440) from the original price ($550) to get the discount amount: $550 - $440 = $110. Next, to calculate the percent discount, we divide the discount amount by the original price and then multiply the result by 100 to convert it to a percentage.
Percent Discount = ($110 / $550) × 100 = 20%
Therefore, the watch was sold at a 20% discount during the mid year sale.
Julia has been saving money for a new Tv. The Tv normally costs $340 but is on sale for 30% off. How much money does Julia need to buy the tv?
Answers
You could find 30% of the original value and subtract that from the original value:
340*0.3=102
340-102=238
OR
You can multiply the original cost by 70% (100%-30%)
340*0.7=238
But either way the amount Julia will need to pay is $238

If the distance from 0 to x on a number line is less than 5, then –5 + x is negative. Always Sometimes Never
Answers
Final answer:
The statement that -5 + x is negative, given the distance from 0 to x on a number line is less than 5, is true sometimes. This depends on the value of x, whether it is a small positive number or any negative number.
Explanation:
The question revolves around the concept of distance on a number line and the calculation of numerical expressions. To understand whether -5 + x is always, sometimes, or never negative given the condition that the distance from 0 to x on a number line is less than 5, let's analyze the scenarios.
First, the absolute value |x| < 5 indicates that x must be between -5 and 5 (not including -5 and 5). This means x can be any value closer to 0 than 5, whether positive or negative.
If x > 0 (but less than 5), then -5 + x would be negative because x cannot neutralize the -5 completely.
For example, if x=4, then -5 + 4 = -1.
If x < 0, then -5 + x is negative since you are adding two negative numbers.
For example, if x=-4, then -5 + (-4) = -9.
The statement -5 + x is negative is true sometimes based on the value of x. If x is a positive number close to 5, the expression may approach 0 but will stay negative. If x is negative, the expression is further negative.
how can you tell that a line segment connecting two points is vertical without graphing the points
Answers
A line segment connecting two points is vertical without graphing the points are intersecting lines if they are not parallel.
What is a line segment?A line segment is a straight line with finite length, and thus, have to endpoints(points on either ends).
For the Parallel lines, it must have the same slope since the slope is like a measure of steepness and since parallel lines are of the same steepness, thus, are of the same slope.
Since the given parallel line has equation y = 5x + 2, thus its slope is 5 and thus, the slope of the needed line is 2 too.
They are intersecting lines if they are not parallel. therefore, the other option is that they are intersecting.
