Patty has a fish pond in her backyard. Even though the air temperature outside has change 35 degrees from sunrise to sunset, the water temperature in the fish pond has only changed 2 degrees. The reason for this lack of temperature change in the water is that it has a high
_____________.
Answer:
The reason for this lack of temperature change in the water is that it has a high specfic heat .
Step-by-step explanation:
Definition of specfic heat .
The amount of heat required per unit mass to raise the temperature by one degree Celsius .
Reason = The reason for this lack of temperature change in the water is due to hydrogen bonding present in water molecules .These hydrogen bonds takes large amount of heat gain for just 1 degree Celsius change in temperature. therefore water temperature increases slowly.
Alex wants to have $3000 in his bank account after 4 years. If the account earns 6% interest compounded 2 times per year, how much should he put in?
In one week, 103 students were absent,17 fewer students were absent than the week before. howe many students were absent in those two weeks?
In the first week, 120 students were absent, and in the second week, 103 students were absent. Total absentees in the two weeks are 223 students.
To determine how many students were absent in two weeks, we first need to find the number of students absent in the first week. We know that 103 students were absent in the second week and that this number is 17 fewer students than the number absent the week before.
Let the number of students absent in the first week be denoted as x.
According to the information given:
x - 17 = 103.To find x, we solve the equation:
x - 17 + 17 = 103 + 17 x = 120 students.Hence, 120 students were absent in the first week. Adding the absences from both weeks:
Total absentees in two weeks = 120 (first week) + 103 (second week) = 223 students

. If you saved $2.00 on january 1, $4.00 on february 1, $8.00 on march 1, $16.00 on april 1, and so on. how much money would you save in one year?
By following a pattern of doubling the saved amount each month, the total amount saved in one year would be approximately $8190.00.
Use the concept of geometric sequence defined as:
A unique kind of sequence called a geometric sequence has a constant ratio between every two succeeding words. This ratio is regarded as one of the geometric sequence's frequent ratios.
Amount saved on January 1: $2.00
Amount saved on February 1: $4.00
Amount saved on March 1: $8.00
Continuing the pattern, the saved amount on April 1 would be $16.00
Since it can be seen that,
The pattern is that the saved amount doubles each month.
Therefore,
To calculate the total amount saved in one year,
Sum up the amounts for each month.
In this case, it would be
$2.00 + $4.00 + $8.00 + $16.00 + $32.00 + $64.00 + $128.00 + $256.00 + $512.00 + $1024.00 + $2048.00 + $4096.00 = $8190
Hence,
The saved amount in one year is $8190

help me with algebra 2
Final answer:
Algebra 2 involves solving simultaneous equations through a multi-step process, simplifying where possible and carefully verifying solutions to ensure reasonableness.
Explanation:
Algebra 2, typically taught in high school, involves solving simultaneous equations for unknown values. The process includes several algebraic steps, where students are advised to eliminate terms where possible to simplify the algebra and carefully check their work at each step. After finding the potential solutions, it's crucial to check the answers to ensure they are reasonable within the context of the problem. This systematic approach to solving algebraic problems, such as equations in one variable, is a methodical and critical part of Algebra 2's curriculum.

A farmer grows two types of grain in his fields. He has a seed budget of $15,000.00 and has spent $5,800.00 to plant wheat seed so far. If barley seed costs $53.00 per acre to plant, what is the maximum number of acres of barley the farmer can plant and still be under budget?
A.283 acres
B.109 acres
C.173 acres
D.174 acres
Answer:
The answer is option D.
Step-by-step explanation:
Total seed budget is = $15000
Amount paid for wheat seeds = $5800
So, amount left is = [tex]15000-5800=9200[/tex]
Now, lets suppose the number of acre of land to be planted by barley seeds be = x
Barley seed costs = $53 per acre.
This means for 53x acres $9200 will be used.
Therefore, [tex]x=\frac{9200}{53}[/tex] = 173.58 acres ≈ 174 acres

one zero of f(x)=x^3-2x^2-5x+6 is 2 what are the zeros of the function
Answer:
Answer:
x=-2, x=1, x=3
Step-by-step explanation:
Step-by-step explanation:
one zero of f(x)=x^3-2x^2-5x+6 is 2 what are the zeros of the function
the following polynomials have the function
f(x)=x^3-2x^2-5x+6
note 2 is not a zero of the function
but x=-2
to find the other zeros we say
f(x)/x+2=x^3-2x^2-5x+6/(x+2)
we have the quadratic equation
x^2-4x+3
factorizing the above, using factorization method
(x^2-3x-x+3)
(x^2-3x)(-x+3)
x(x-3)-1(x-3)
(x-1)(x-3)
x=1, x=3
the zeros of the function are
x=-2, x=1,x=3
substituting the values back into the function
we have zero
f(1)=1^3-2(1)^2-5(1)+6
F(1)=0
Answer:
-1 and -3 are the other zeroes
Find the weighted average of these values
Value Weight
5.00 75.0 %
6.00 15.0 %
7.00 10.0 % ...?
To find the weighted average of given values, multiply each value by its weight, sum the results, yielding a weighted average of 5.35.
Explanation:The question is asking to find the weighted average of given values with their corresponding weights. To calculate a weighted average, each value is multiplied by its weight, and then the results are summed up. The formula used is \(Weighted\ Average = (Value_1 \times Weight_1) + (Value_2 \times Weight_2) + \cdots + (Value_n \times Weight_n)\).
Applying the given values and weights:
\(5.00 \times 75.0\% = 3.75\)\(6.00 \times 15.0\% = 0.90\)\(7.00 \times 10.0\% = 0.70\)Summing the results: \(3.75 + 0.90 + 0.70 = 5.35\).
Therefore, the weighted average of these values is 5.35.
The weighted average of the item is 5.35 weight units
The steps used to find the weighted average are as follows;
The weighted average is a technique or method used to find the average of a list of items, where the contribution of each item to the sum of the measurements are different or proportional to a specified measurement of the quantity
The mass and percentage by weight of the items indicates that we get;
The contribution of the item with a value of 5.00 is; 5 × 75% = 3.75
The contribution of the item with a value of 6.00 is; 6 × 15% = 0.9
The contribution of the item with a value of 7 is; 7 × 10% = 0.7
The weighted average of the substance is therefore; 3.75 + 0.9 + 0.7 = 5.35
