eighteen 2.5- gallon buckets are needed to fill a cistern of water
How many 3-gallon buckets of water will fill the cistern.
Answer:
15 3-gallon buckets of water will fill the cistern
Step-by-step explanation:
Eighteen 2.5- gallon buckets are needed to fill a cistern of water
This means, 2.5 gallon buckets in 18 places
2.5 gallons × 18 = 1 cistern of water
45 gallons = 1 cistern of water
How many 3-gallon buckets of water will fill the cistern.
Number of 3-gallon bucket in a cistern = Total gallons of bucket in one cistern / 3-gallon buckets
= 45 gallons / 3-gallon buckets
= 15
Number of 3-gallon bucket in a cistern = 15
15 3-gallon buckets of water will fill the cistern

Answer:
the percentage of 80L from 400L is 20%
Step-by-step explanation:
in order to find the percentage of something you need to divide the total amount from the number you want to find the percentage of:
80 / 400 = 0.2
we now multiply 0.2 by 100 to turn it into a percentage:
0.2 * 100 = 20%
Find the measure of angle J
Answer:
36
Step-by-step explanation:
Answer: 36°
Step-by-step explanation: The three angles of a triangle always equal 180 when added together. Since we have two angles already, we simply subtract those from 180
180 - 115 = 65
65 - 29 = 36
J = 36

Mr. Sampson fills the family pool with water for the summer. After two hours, the water has reached a depth of 2.5 feet. After three hours, the water level has risen to 3 ¾ feet. If the relationship between time and water depth is proportional., what is the constant of proportionality?
Answer: 1.25
Step-by-step explanation:
To solve this, we.will use the formula,
y = kx
where,
y = water depth
k = constant of proportionality
x = time
Using y = kx
2.5 = 2k
k = 2.5/2
k = 1.25
Also,
y = kx
3.75 = 3k
k = 3.75/3
k = 1.25

I hope I helped :)
The adam balance at the end of the month is $622.09.
Given that,
The beginning balance in his checking account is $174.85.And, the checkbook transactions contain the balance of $28,316.38, and $102.86.Based on the above information, the calculation is as follows:
= $174.85 + $316.38 + $28 + $102.86
= $622.09
Therefore we can conclude that the adam balance at the end of the month is $622.09.

Calculate the average rate of change for the given graph from x = 3 to x = 5 and select the correct answer below.
Answer:
Average rate of change between x = 3 to x = 5 is 0.
Step-by-step explanation:
Given quadratic function s passing through two points (3, 0) and (5, 0).
Average rate of change of a function between x = a and x = b is given by,
Average rate of change = [tex]\frac{f(b)-f(a)}{b-a}[/tex]
From the graph attached,
Average rate of change between x = 3 to x = 5 will be,
= [tex]\frac{f(5)-f(3)}{5-3}[/tex]
= [tex]\frac{0-0}{5-3}[/tex]
= 0
Therefore, average rate of change between x = 3 to x = 5 is 0.
Answer: The average rate of change for the given graph from x=3 to x=5 is 0
Which fraction names the shaded part of the set?
The fraction of the shaded part of the set is 1/3.
Given is a figure in which there are total 12 parts with 4 parts shaded.
We need to find the fraction of the shaded part of the set,
To find the fraction of the shaded part of the set, we need to determine the ratio of the number of shaded parts to the total number of parts.
In this case, the total number of parts is 12, and the number of shaded parts is 4.
Therefore, the fraction of the shaded part can be calculated as follows:
Fraction of shaded part = Number of shaded parts / Total number of parts
Fraction of shaded part = 4 / 12
Simplifying the fraction, we get:
Fraction of shaded part = 1 / 3
So, the fraction of the shaded part of the set is 1/3.

Calcium-41 is being used in studies testing the effectiveness of drugs for preventing osteoporosis. The half-life of calcium-41 is 100,000 years. If 20 grams of calcium-41 are present initially, how long would it take until only 2 grams
remains?
Answer:
332,193 years
Step-by-step explanation:
From the question above, we are to calculate the time in an half life question, hence, the formula is given as
t = In(Nt/No) ÷ -(In2/t½)
Where
t = time is takes for an substance to decay or reduce
Nt = Amount of sample after time = 2g
No = Initial amount of sample = 20g
t½ = Half life = 100,000 years
Hence,
t = In(2/20) ÷ (In 2/ 100,000)
t = 332192.80948874 years
Approximately = 332,193 years
Write a quadratic equation with 7 and as its roots. Write the equation in the form ax^2+ bx + C = 0,
where a, b, and c are integers.
The equation in the form ax² + bx + c of the quadratic equation with 7 and 2/5 as it root is x² - 33 / 5 x + 14 / 5
The root of the quadratic equation are 7 and 2/5 .
The equation should be written in the form
ax² + bx + c
where
a, b and c are integers.
Therefore,
x - (7) and x - 2/5
(x - 7)(x - 2/5)
open the bracket
x² - 2/5x - 7x + 14 / 5
x² - 33 / 5 x + 14 / 5
where
a = 1
b = -33 / 5
c = 14 / 5

express 0.0003 in Scientific notation by counting decimal places
Answer:
When we write numbers in scientific notation, we must put the first non-zero digit ahead of the decimal. In this case, the decimal would be behind the 3. Because we moved the decimal places four times to the right, our exponent will be 4. Thus,
3.00 x 10⁻⁴
we can express 0.0003 as 3 × 10⁻⁴ in scientific notation.
To express 0.0003 in scientific notation, we count the number of decimal places from the original number until we have a single non-zero digit before the decimal point. In this case, we have four decimal places before the non-zero digit (3).
Thus, we can express 0.0003 as 3 × 10⁻⁴ in scientific notation. The negative exponent (-4) indicates that we move the decimal point four places to the left to obtain the original value.
In summary, by counting the decimal places, we can express 0.0003 as 3 × 10⁻⁴ in scientific notation.
