Final Answer: 11.5%
The total number of students on the honor roll increased by 11.5%.
What is the percentage?The percentage is defined as a ratio expressed as a fraction of 100.
The percentage increase in the number of boys on the honor roll is 5%, which means that the number of boys on the honor roll this year is 1.05 times the number of boys on the honor roll last year:
1.05 x 140 = 147
The percentage increase in the number of girls on the honor roll is 25%, which means that the number of girls on the honor roll this year is 1.25 times the number of girls on the honor roll last year:
1.25 x 68 = 85
Therefore, the total number of students on the honor roll this year is:
147 + 85 = 232
The percentage increase in the total number of students on the honor roll is:
((232 - 208) / 208) x 100% = 11.5385%
Rounding to the nearest tenth gives an answer of 11.5%.
Therefore, the total number of students on the honor roll increased by 11.5%.

Otto is told the average low temperature in January is 16.1∘C cooler than the average low temperature in November. What equation can Otto use to find the average low temperature in January?
Answer:
x - 16.1°C
Step-by-step explanation:
Given that average low temperature in January is 16.1 cooler Than average low temperature in November
Let average low temperature in November = x
Since, average low temperature in January is cooler than average low temperature in November, then, January temperature is less Than in November
Hence,
Average low temperature in January :
[Average low temperature in November - 16.1°C]
(x - 16.1°C)

5(x - 1) and 5x - 1
is it equivalent
Answer:
no
Step-by-step explanation:
5(x - 1) = 5x - 5
5x - 1 = 5x - 1
No, it is not equivalent
The required, 5(x - 1) and 5x - 1 are not equivalent expressions.
Let's expand 5(x - 1):
5(x - 1) = 5 * x + 5 * (-1) = 5x - 5
On the other hand, 5x - 1 is already in its simplified form.
As you can see, the expressions 5(x - 1) and 5x - 1 have different forms. The first expression involves distributing the 5 to both terms inside the parentheses, while the second expression is already simplified and cannot be further combined.
For example, if we substitute x = 2 into both expressions, we get:
5(2 - 1) = 5 * 1 = 5
5 * 2 - 1 = 10 - 1 = 9
Since 5 and 9 are not equal, it confirms that the two expressions are not equivalent.

The manager of the zoo where the ticket price for an adult is $9.50 and the ticket price for a child is $6.50 wants to make at least $800 on a Saturday. Let x be the number of adult tickets and y be the number of child tickets
Complete Question
The manager of the zoo where the ticket price for an adult is $9.50 and the ticket price for a child is $6.50 wants to make at least $800 on a Saturday. Let x be the number of adult tickets and y be the number of child tickets. Choose the inequality that shows the numbers of tickets that need
A) 9.50x + 6.50y ≥ 800
B) 9.50x + 6.50y < 800
C) 9.50x + 6.50y > 800
D) 9.50x + 6.50y ≤ 800
Answer:
A) 9.50x + 6.50y ≥ 800
Step-by-step explanation:
Let x be the number of adult tickets and y be the number of child tickets
We are told that the zoo wants to make at least $800, this means greater than or equal to $800
Therefore, inequality equation is given as:
$9.50 × x + $6.50 × y ≥ 800
= 9.50x + 6.50y ≥ 800
Therefore option A) 9.50x + 6.50y ≥ 800 is correct.

Bethany can mow her lamily's lawn in 4 hours. Her brother coin can mow the lawn into hoursWhich equation can ve
used to find the number of hours, x, it would take for Bethany and Colin to mow the lawn together?
Answer:
1/x = 1/4 + 1/3
Step-by-step explanation:
In 4 hours Bethany did the whole fraction 1 of the house.
In 1 hour he would do 1/4 of it.
In 3 hours Colin did the whole fraction 1 of the house.
In 1 hour he would do 1/3 of it.
In 1 hour they would both do (1/4 + 1/3)
If it takes both of them x hours to finish 1 whole fraction of the house.
In 1 hour they will both do 1/x
That means that:
1/x = 1/4 + 1/3
That is the equation. x can be solved for.

Now, By options;
The correct function has a point (2, 20).
Hence, It can satisfy the equation of parabola.
Now, By option 3;
⇒ f (x) = 2 (x + 1)² + 2
⇒ 20 = 2 (2 + 1)² + 2
⇒ 20 = 2 (9) + 2
⇒ 20 = 18 + 2
⇒ 20 = 20
Hence, The correct function which represents the situation is,
⇒ f (x) = 2 (x + 1)² + 2
