The population of Pleasanton is 17 % higher. (Right choice: D)
According to the statement, the population of Pleasanton is reduced by a factor of 0.9 in the 1980s and increased by a factor of 1.3 in the 1990s. The increase rate is found by means of this formula:
[tex]x =[(0.9)\cdot (1.3)-1]\cdot 100[/tex]
[tex]x = 17\,\%[/tex]
The population of Pleasanton is 17 % higher. (Right choice: D)

The population of Pleasanton at the end of the 1990s is 17% higher than the population in 1980.
Explanation:To compare the population of Pleasanton in the 1990s with the population in 1980, we need to consider the changes that occurred in each decade. In the 1980s, the population decreased by 10%. This means that if the population in 1980 was represented by 100, it would have decreased to 90 by the end of the decade.
In the 1990s, the population increased by 30%. Using the population of 90 at the beginning of the decade, the population at the end of the 1990s would be 90 + (30% of 90) = 90 + 27 = 117.
So, the population of Pleasanton at the end of the 1990s is 117, which is 17% higher than the population in 1980. Therefore, the correct answer is D) It is 17% higher.
A triangle in the coordinate plane has coordinates of (2,3), (-4,-5), and (-2, 4). It is translated 3 units down. What are its new coordinates?
A (5,3), (-1,-5), (1,4)
B (2,6), (-4,-2), (-2, 7)
C (2,0), (-4,-8), (-2, 1)
D (-1,3), (-7,-5), (-5,4)
I need this done fast
translated 3 units down means the x stays the same and you subtract 3 from the Y
so (2,3) becomes (2,0)
(-4,-5) = (-4,-8)
and (-2,4) = (-2,1)
so new coordinates are C. (2,0), (-4,-8), (-2,1)
at a yard sale you find 5 paperback books by your favorite author. each book is $0.75. write a rule for the amount (in dollars) you spend as a function of the number of books you buy.
The function for the amount of money left after buying books is y = 10 - 0.75x.
Let x represent the number of books you buy. Each book costs $0.75, so the total cost for x books is 0.75x. You start with $10.
Therefore, the amount of money you have left, y, can be represented by the function:
y = 10 - 0.75x
For example, if you buy 3 books, the remaining money would be:
y = 10 - 0.75(3)
= 10 - 2.25
= 7.75
The complete question is:
At a yard sale, you find 5 paperback books by your favorite author. You have $10 in each book is priced at $0.75. Write a rule for the amount of money you have left as a function of the number of books you buy.

Rohan did a survey in four bird parks and wrote the following observations:
Bird Park Survey
Park Number of Yellow Birds Total Number of Birds
P 33 53
Q 20 48
R 54 90
S 44 83
Based on the survey, which park had the greatest percentage of yellow birds?
Park P
Park Q
Park R
Park S
Answer: Park P
Step-by-step explanation:
Since, According to the question,
Number of yellow bird in park P = 33
Total number of the bird in park P = 53
Thus, the percentage of yellow bird in park P = [tex]\frac{33}{53} \times 100[/tex]= 62.264150943% ≈ 62 %
Number of yellow bird in park Q = 20
Total number of the bird in park Q = 48
Thus, the percentage of yellow bird in park P = [tex]\frac{20}{48} \times 100[/tex]=41.666666666% ≈ 42%
Number of yellow bird in park R = 54
Total number of the bird in park R = 90
Thus, the percentage of yellow bird in park R = [tex]\frac{54}{90} \times 100[/tex]= 60 %
Number of yellow bird in park S = 44
Total number of the bird in park S = 83
Thus, the percentage of yellow bird in park P = [tex]\frac{44}{83} \times 100[/tex]=53.012048192 % ≈ 53 %
Since, 62% > 60% > 53% > 42%
Therefore, highest percentage of the yellow bird is 62 %

3/8 c−2= 3/2 c−12 helpp
The solution involves clearing the equation of fractions, rearranging terms to isolate the variable c, and then solving for c by dividing both sides by 9 to obtain c = 80/9.
Explanation:The student is asking for help solving a linear equation. To assist with this mathematics problem, it's crucial to use algebraic methods to isolate the variable c. Here is the step-by-step solution:
Given:
3/8 c − 2 = 3/2 c − 12
First, let's clear the fractions by multiplying every term by 8 to get rid of the denominators:
8(3/8 c) − 8(2) = 8(3/2 c) − 8(12)
Which simplifies to:
3c − 16 = 12c − 96
Next, subtract 3c from both sides to move all terms with c to one side:
− 16 = 9c − 96
Now, add 96 to both sides to isolate the c term:
80 = 9c
Finally, divide both sides by 9 to get the value of c:
c = 80 / 9

The number m and 58 are additive inverses.
Drag and drop 58 and m to their correct positions on the number line.
Drag and drop the label “Sum” to the sum of 58 and m.
Answer:
[tex]m=-\frac{5}{8}[/tex]
Step-by-step explanation:
We have been given that the number m and 58 are additive inverses.
We know that two numbers are additive inverses when they add up-to 0.
[tex]\frac{5}{8}+m=0[/tex]
[tex]\frac{5}{8}-\frac{5}{8}+m=0-\frac{5}{8}[/tex]
[tex]m=-\frac{5}{8}[/tex]
Therefore, the additive inverse of [tex]\frac{5}{8}[/tex] would be [tex]-\frac{5}{8}[/tex].
