Answer:
42% acid
Step-by-step explanation:
Suppose that these two storage containers are filled to complete capacity?
That makes the second container have 3 volume parts and the first container having 2 volume parts.
v*(1.50)= (3/2)*v
First Container 2v 30% acid
Second Container 3v 50% acid
The mixture of all of this is in the third container. Two parts plus three parts is 5 parts for the mix volume.
=(2*30+3*50)/5
=210/5
=42
So,
42 % Acid, mixture
Final answer:
After calculating the quantities of acid from both containers and their total volume, the final acid concentration in the mixture in the third container is found to be 42%.
Explanation:
The student has asked about finding the percentage of acid in a third container after mixing two solutions with different acid concentrations. This question involves proportion and percentage calculations, which are commonly covered in high school mathematics.
To find the final concentration of acid in the third container, we can use the formula final concentration = (quantity of acid in container 1 + quantity of acid in container 2) / total volume. Assume the first container has a volume of V liters. Since the second container is 50% larger, it has a volume of 1.5V liters.
Acid in the first container = V liters × 30% = 0.3V liters
Acid in the second container = 1.5V liters × 50% = 0.75V liters
Total volume = V + 1.5V = 2.5V liters
Thus, the final concentration of acid = (0.3V + 0.75V) / 2.5V = 1.05V / 2.5V = 42%.
The final acid concentration in the third container is 42%.
A 45 foot ladder is used to clean the
gutters at your house. How far away from
the house should you put the ladder in
order for it to reach the 40 foot high
gutter? Round your answer to the nearest
tenth.
5 feet.
Answer:
20.62
Step-by-step explanation:
In this instance, we are going to use the pythagorean theorem.
The height of the gutter will be a leg of the triangle, and the ladder will be the hypotenuse. The formula is
[tex]a^{2} + {b}^{2} = {c}^{2} [/tex]
While A and B are legs and C is the hypotenuse. We are trying to find B, the distance from the house.
So plug A and C in:
[tex] {40}^{2} + {b}^{2} = {45}^{2} [/tex]
Now figure it out: first you square 40 and 45:
[tex]1600 + {b}^{2} = 2025[/tex]
Isolate the B term: subtract 1600 from both sides
[tex] {b}^{2} = 425[/tex]
Now take the square root of both sides to find B
[tex]b = 20.62[/tex]
And that's your answer
Answer:
20.6 feet
Step-by-step explanation:
The Pythagorean theorem can tell you the distance from the house the base of the ladder may be for it to reach 40 feet up. If that distance is represented by x, then it tells you ...
45^2 = x^2 + 40^2
x = √(2025 -1600) = √425
x ≈ 20.6
The ladder will reach to 40 feet high when the base is 20.6 feet from the house.
_____
Comment on ladder distance
The ladder safety association recommends an angle with the ground of about 75°. That corresponds to a distance from the house of about 10 feet. If the ladder is 20 feet away, it will barely reach the gutter, so placing it at that distance would probably not be safe.
An appropriate answer to this question is "10 feet", not based on math, but based on safety. At that distance the end of the ladder will extend about 3.7 feet beyond the gutter.

A computer programmer worked for 10 hours and earned $70,which is a rate of dollars per hour.
When a programmer works for 10 hours and earns $70, the rate of dollars per hour earned by the programmer is $7.
A computer programmer worked for 10 hours and earned $70.
To calculate the rate per hour, we divide the total earnings by the number of hours worked. In this case,
$70 ÷ 10 hours = $7 per hour.
Therefore, the programmer earned $7 per hour.

Y=3x+13
Y=x-3
Answer:
x = -8
Y = -11
Step-by-step explanation:
Given
Y = 3x + 13
Y = x - 3
Substitute x - 3 for Y in the first equation
We have
Y = 3x + 13
x - 3 = 3x + 13
Add 3 to both sides
x - 3 + 3 = 3x + 13 + 3
x = 3x + 16
Subtract 3x from both sides
x - 3x = 3x - 3x + 16
-2x = 16
Divide both sides by -2
x = 16/-2
x = -8
Now substitute -8 for x in any of the above equations to get Y.
Using the second equation, we have
Y = x - 3
Y = -8 - 3
Y = -11

Whats the product of 2/3 × 36
Answer:
24 :)
Step-by-step explanation:
2 / 3 x 36 = ?
First of all, note that 36 is the same as 36/1 since 36 divided by 1 is 36. Therefore, start by setting up the problem like this:
36 / 1 x 2 / 3
Multiply the numerators together (36 x 2 = 72) and multiply the denominators together (1 x 3 = 3) and make it into one fraction like so:
72 / 3
The greatest common factor of 72 and 3 is 3. Minimize the fraction by dividing the numerator and the denominator by its greatest common factor to get:
24 / 1
Convert the improper fraction above to a whole number to get the answer:
24

Grandma says Baby Bertha (BB) should get $1000 at birth plus $50 per year. Grandpa disagrees; he thinks BB should get $1000 at birth plus an additional 4% of the accumulated amount each year. Grandma and Grandpa will continue to contribute additional funds into the account as long as BB doesn’t make a withdrawal. Which option should BB’s parents select? Why?
BB's parents should choose Grandpa's option, where Baby Bertha (BB) receives $1000 at birth plus an additional 4% of the accumulated amount each year.
Explanation:In Grandpa's option, the annual contribution grows dynamically with the accumulated amount, creating compounding growth. Let's denote the accumulated amount at the end of year \(n\) as A_n. The contribution at year \(n\) can be expressed as \(0.04 \times A_n\). BB's total amount at the end of year \(n\) can be written as:
\[A_n = 1000 \times (1 + 0.04)^{n}.\]
This formula considers the initial $1000 and the 4% annual growth on the accumulated amount. With compounding, this option ensures that BB's fund grows significantly over time.
Grandma's option, on the other hand, provides a fixed annual amount of $50, which does not consider the potential growth through interest or investment. Over time, the fixed contribution might not keep up with inflation, and the fund may not accumulate as much as Grandpa's option.
In summary, Grandpa's option is financially advantageous due to compounding growth, allowing BB's fund to grow more substantially over the years. This strategy aligns with long-term financial planning, providing a better financial foundation for Baby Bertha's future.
Find the sum of the interior angles of a decagon
Answer:
1440 degrees
Step-by-step explanation:
The sum of the interior angles of a polygon can be found by
(n-2)*180
where n is the number of sides
a decagon has 10 sides, so n=10
(10-2) *180
8*180
1440
The sum of all the interior angles of a decagon is calculated as (n-2) × 180°. For a decagon, where n is 10, the sum is 1440°.
The correct option is (C).
The sum of all the interior angles of a decagon can be found using the formula for calculating the sum of interior angles of any polygon, which is (n-2) × 180°, where n is the number of sides of the polygon. In the case of a decagon, n is 10. Therefore, the sum of all the interior angles of a decagon is (10-2) × 180° = 8 × 180° = 1440°. Thus, the correct answer is C.1440°.

Use the Distributive Property to solve the equation
4(x+2)=16
Answer:
Step-by-step explanation:
4(x+2) = 16
4x + 8 = 16
4x =16-8
4x = 8
x = 8/4
x = 2
The solution to the equation 4(x + 2) = 16 is x = 2.
The Distributive Property states that a(b + c) = ab + ac. Apply this to the equation:
4(x + 2) = 4 * x + 4 * 2.
Thus, the equation becomes:
4x + 8 = 16.
To solve for x, first subtract 8 from both sides of the equation:
4x + 8 - 8 = 16 - 8
4x = 8.
Divide both sides of the equation by 4:
4x / 4 = 8 / 4
x = 2.

An=a^1*r^n-1 that’s the formula for the equation I kinda dunno how to exactly solve it though
Answer:
see explanation
Step-by-step explanation:
The n th term of a geometric sequence is
[tex]a_{n}[/tex] = a[tex](r)^{n-1}[/tex]
where a is the first term and r the common ratio
Here a = 15, thus
[tex]a_{5}[/tex] = 15[tex](r)^{4}[/tex] = [tex]\frac{243}{125}[/tex] ( divide both sides by 15 )
[tex]r^{4}[/tex] = [tex]\frac{243}{1875}[/tex], thus
r = [tex]\sqrt[4]{\frac{243}{1875} }[/tex] = [tex]\frac{3}{5}[/tex]
Multiply the previous term by [tex]\frac{3}{5}[/tex] to obtain the next term
15 × [tex]\frac{3}{5}[/tex] = 9
9 × [tex]\frac{3}{5}[/tex] = [tex]\frac{27}{5}[/tex]
[tex]\frac{27}{5}[/tex] × [tex]\frac{3}{5}[/tex] = [tex]\frac{81}{25}[/tex]
[tex]\frac{81}{25}[/tex] × [tex]\frac{3}{5}[/tex] = [tex]\frac{243}{125}[/tex]
Thus the sequence is
15, 9, [tex]\frac{27}{5}[/tex], [tex]\frac{81}{25}[/tex], [tex]\frac{243}{125}[/tex]
Without multiplying, tell which is greater: 4/5 x 45 or 2/3 x 45. Explain.
Answer: It is 4/5 x 45
Step-by-step explanation: Hope i helped please mark brainliest!
I know there is suppose to be no multiplying but if you mulitply in your head 4/5 x 45 is 36 and 2/3 x 45 is 30
therefore, 4/5 x 45 is greater!
also, if not multiplying 0.8(5/4) is greater than 0.667(2/3). Therefore, 4/5 is greater than 2/3.
Without multiplying, 4/5 x 45 is greater than 2/3 x 45 because the fraction 4/5 is greater than 2/3 when both are compared using a common denominator.
Explanation:To answer which is greater without multiplying, we can look at the fraction multiples of 45 in the problems 4/5 x 45 and 2/3 x 45. Since both expressions involve the same whole number (45), we can compare the fractions 4/5 and 2/3 to determine which product is greater. By converting the fractions to have a common denominator, we can see that 4/5 is equivalent to 24/30, and 2/3 is equivalent to 20/30. Therefore, 4/5 is greater than 2/3, meaning that 4/5 x 45 is greater than 2/3 x 45.

Two mixed numbers as [tex]\frac{5}{6}[/tex] and [tex]\frac{5}{12}[/tex] the least common denominator (LCD) is 12.
Step-by-step explanation:
The least common denominator (LCD) is the smallest number that can be a common denominator for a set of fractions. Also known as the lowest common denominator, it is the lowest number you can use in the denominator to create a set of equivalent fractions that all have the same denominator.
Steps to find the LCD of fractions, integers and mixed numbers:
Convert integers and mixed numbers to improper fractionsFind the LCD of all the fractionsRewrite fractions as equivalent fractions using the LCDLet's us have two mixed numbers as [tex]\frac{5}{6}[/tex] and [tex]\frac{5}{12}[/tex].
Equivalent Fractions with the LCD
[tex]\frac{5}{6}[/tex] = [tex]\frac{10}{12}[/tex]
[tex]\frac{5}{12}[/tex] = [tex]\frac{5}{12}[/tex]
For the denominators (6, 12) the least common multiple (LCM) is 12. Therefore, the least common denominator (LCD) is 12.
Final answer:
The mixed numbers 1 1/4 and 2 1/3 can be converted to have the lowest common denominator of 12, resulting in 1 3/12 and 2 4/12 respectively.
Explanation:
To write two different mixed numbers where the lowest common denominator (LCD) is 12, we can choose denominators that are factors of 12 and numerators that result in proper fractions (where the numerators are less than the denominators). An example would be 1 1/4 and 2 1/3. Here's how these mixed numbers have 12 as their common denominator:
For 1 1/4, the denominator 4 is a factor of 12. To convert 1/4 to a denominator of 12, multiply the numerator and denominator by 3. So, 1 1/4 becomes 1 3/12.For 2 1/3, the denominator 3 is also a factor of 12. To convert 1/3 to a denominator of 12, multiply the numerator and denominator by 4. So, 2 1/3 becomes 2 4/12.Now we have two mixed numbers with the LCD of 12.
