Use an exponential expression to calculate the area covered by purple loosestrife 7 years from now. Is this a valid
prediction? What does this result tell you about the constraints on the exponential model?
The area of the wetland that will be covered in purple loosestrife 7 years from now is modeled by this expression.
500(1.2)^7
After evaluating the expression, the model predicts that approximately 1,792 acres of the wetland will be covered in purple loosestrife 7 years from now. This is not a valid prediction because the total area of the wetland is only 1,240 acres. So a constraint on the model is that the value of the expression 500(1.2)^t must be less than or equal to 1,240.
Answer: 500(1.2)^7

The perimeter of a rectangle is 54 inches.
Its length is 15 inches.
What is the width (w)?
Answer:
12
Step-by-step explanation:
if the perimeter is 54, and the length is 15,
first double the length (to include both sides of the rectangle):
15(2)=30
subtract that by 54:
54-30=24
to find the width we would divide 24 by 2, because 24 represents both sides of the rectangle:
24/2=12
the width is 12.

3 more than a number is greater than 27
Answer:
n+3 > 27
Step-by-step explanation:
The inequality that represents the statement is x + 3 > 27 and the values of (x) which are greater than 24 are the possible solutions of this inequality.
What is inequality?In mathematics, an inequality is a relation which makes a non-equal comparison between two numbers or other mathematical expressions. It uses the following following operators to make comparison → >, <, ≤, ≥.
Given is the following mathematical verbal statement -
3 more than a number is greater than 27
We will first convert it into the inequality and then solve it. The inequality expression can be written by assuming a number. Let it be (x). So, we can write -
x + 3 > 27
Subtract 3 from both sides -
x + 3 - 3 > 27 - 3
x > 24
The inequality given above represents the statement and the values of (x) which are greater than 24 are the possible solutions of this inequality.
Therefore, the inequality that represents the statement is x + 3 > 27 and the values of (x) which are greater than 24 are the possible solutions of this inequality.

today reza ate 20 grapes which is 400% as many grapes as he ate yesterday. explain how to use equal ratios to find the number of grapes reza ate yesterday
Answer:
Write 400% as the ratio 400/100. To find an equivalent ratio, you know that 400 divided by 20 is 20, so 100 divided by 20 will give you the answer. 100 ÷ 20 = 5. Reza ate 5 grapes yesterday.
Brainliest please!
Answer:
What you must do for this case is to extract the relationship of the grapes that were eaten yesterday among the grapes that were eaten today.
To do it, let:
x: number of grapes that Reza ate yesterday
(x / 20) = (100/400).
Clearing x we have:
x = (100/400) * (20) = 5
answer
the number of grapes Reza ate yesterday was 5

A 50 ohm load dissipates 100 W of power. How much voltage is across the load?
Answer:
5000 volts
Step-by-step explanation:
we know v×IR so voltage equals current*resistance so 50*100 so 5000
9514 1404 393
Answer:
about 70.7 V
Step-by-step explanation:
The relation between power and voltage and resistance in a resistive circuit is ...
P = V^2/R
so ...
V = √(PR)
V = √(100·50) = √5000
V ≈ 70.7 . . . . volts

3. 96 students are enrolled in the Dance Program at Castillero. Of those students, 54 are eighth-graders. The remaining students are 6th or 7th graders. What percentage of the students are not eighth graders?
Answer:
1) new price of the clock is $14.4
2) Kyra scored 70% marks
3) 43.75% students are not eighth graders
Step-by-step explanation:
1. A store manager marked up the price of a $12 clock by 20%. What is the new price of the clock?
Price of Clock = $12
Mark up = 20%
We need to find new price of clock.
The price of clock can be found by finding 20% of 12 and then adding that amount in original price.
So, finding 20% of 12
[tex]20\% of 12 \\=\frac{20}{100}\times 12\\=2.4[/tex]
So 20% of 12 is 2.4
Now finding new price:
New Price = Actual Price + Mark up
New Price = 12 + 2.4
New Price = 14.4
So, new price of the clock is $14.4
2. On a math quiz, Kyra answered 7 of 10 questions correctly. Express her quiz score as a percent.
Total questions = 10
Correct answers = 7
We need to express her quiz score as percent
It can be found using formula: [tex]Percent Score = \frac{Obtained\:Marks}{Total\:Marks}\times 100\%\\[/tex]
Putting values and finding percentage
[tex]Percentage = \frac{Obtained\:Marks}{Total\:Marks}\times 100\%\\\\Percentage = \frac{7}{10}\times 100\%\\Percentage = 70\%[/tex]
So, Kyra scored 70% marks
3. 96 students are enrolled in the Dance Program at Castillero. Of those students, 54 are eighth-graders. The remaining students are 6th or 7th graders. What percentage of the students are not eighth graders?
Total Students = 96
Number of eighth-graders students = 54
Remaining students = 96 - 54 = 42
So, 42 students are 6th or 7th graders
We need to find percentage of the students are not eighth graders.
[tex]\frac{42}{96}\times 100\%\\=43.75\%[/tex]
So, 43.75% students are not eighth graders
Bernard designs motorized bicycles at Smart Gear Technologies. His total earnings are
$54,000 this year. Bernard pays $201 in payroll taxes for every $1,000 he earns.
What is Bernard's net income for this year?
Answer: $43146
Step-by-step explanation:
So his total earning is $54,000. He has to pay $201 for every $1,000 he earns. So 54,000/1,000= 54. So now he has to pay 54*201=10854, 54000-10854=43146. His net income for this year is $43146.

There are 9 red marbles and 4 blue marbles in a bag? What is the ratio blue marbles to all marbles in the bag? Ratio of blue marbles to red marbles
Answer:
4/13
Step-by-step explanation:
There are 9+4=13 marbles in total.
So, the ratio is 4/13.
The ratio of blue marble to all marbles is 4: 13 while blue marbles to red marbles are 4: 9.
What are the ratio and proportion?The ratio is the division of the two numbers.
For example, a/b, where a will be the numerator and b will be the denominator.
Proportion is the relation of a variable with another. It could be direct or inverse.
Given that,
Number of blue marbles = 4
Number of red marbles = 9
Total number of marbles = 9 + 4 = 13
The ratio of blue to total marble = 4/13
The ratio of blue to red = 4/9
Hence "The ratio of blue marble to all marbles is 4: 13 while blue marbles to red marbles are 4: 9.".
