Answer:
your answer is A chemical weathering
Step-by-step explanation:
as when volcanic gasses and atmospheric gasses mix it can become a sort of acidic rain in some cases I hope this answer helps I apologize for any wrong answers this is not my best subject but I wanted to attempt this as I k ow a small amount about it!
The process described in the question is known as acid rain, which is a type of chemical weathering. The correct answer would be option (A) chemical weathering.
What is acid rain?When atmospheric and volcanic gases mix with water in the atmosphere, they can form acids such as sulfuric acid and nitric acid. These acids can then drop to the earth as acid rain. In rare situations, the mixing of volcanic and atmospheric gases can result in acidic rain.
Acid rain can cause chemical reactions with minerals in rocks and soil, dissolving them over time. This can lead to the breakdown of the rock or soil, which is an example of chemical weathering.
Thus, the process described in the question is known as acid rain, which is a type of chemical weathering.
Hence, the correct answer would be option (A) chemical weathering.

Rewrite the fraction in the sentence below as a percentage.
In 2010, a fire destroyed
3/10 of the farmer's crops.
Answer: 30%
Step-by-step explanation:
Method 1:
The original fraction is [tex]\frac{3}{10}[/tex]
To convert to a percent, the denominator should be equal to 100 (since percent is per 100)
Multiply the top and bottom by 10
[tex]\frac{3}{10} * \frac{10}{10} = \frac{30}{100}[/tex]
Since the numerator is 30, 3/10 as a percent is 30%
Method 2:
The original fraction is [tex]\frac{3}{10}[/tex]
To convert to a percent, first convert the fraction to a decimal (do 3 ÷ 10)
0.3
10 | 3 0
-30
-------------
0
You get 0.3
Now multiply the decimal by 100
0.3 * 100 = 30
30%
Method 3:
The original fraction is [tex]\frac{3}{10}[/tex]
[tex]\frac{3}{10} = \frac{x}{100} \\10x = 300\\x = 30[/tex]
cross-multiply to solve the equation

Consider a quadratic equation with integer coefficients and two distinct zeros. If one zero is irrational, what is true about the other zero
Answer:
Step-by-step explanation:
irrational roots always occur in pairs.
Other root is also irrational and is negative of first zero.
If a quadratic equation with integer coefficients and two distinct roots have one irrational root then another root is also irrational .
What is quadratic equation ?Any equation of the form [tex]ax^{2}+bx+c=0[/tex] where x is variable and a, b, and c are any real numbers where a ≠ 0 is called quadratic equation .
Let assume quadratic equation is
[tex]ax^{2}+bx+c=0[/tex]
Given that coefficients are integer and roots are distinct
we know root of quadratic equation are
[tex]x=\frac{-b \pm \sqrt{b^{2}-4 a c}}{2 a}[/tex]
As roots are distinct
[tex]b^2-4ac > 0\\[/tex]
and one root is irrational so [tex]b^2-4ac[/tex] is not a perfect square
Hence another root is also irrational .
If a quadratic equation with integer coefficients and two distinct roots have one irrational root then another root is also irrational .

Carlos has 2.6 meters of wire. He has 3 projects for which he needs 0.9 meters each. Does carlos have enough wires?
Answer: Carlos does not have enough wires by 0.1 meters
Step-by-step explanation:
To determine if Carlos has enough wires, you need to find out the total amount of wires needed and then compare this to the amount of wires that Carlos has already.
= 0.9 + 0.9 + 0.9
= 2.7 meters
Carlos has 2.6 meters of wire but needs 2.7 meters.
Carlos therefore, does not have enough wires.

If f(x) = 3LX-2], what is f(5.9)? 9 10 11 12
Answer: 12
Step-by-step explanation:
We know that , the ceiling function y = [x] is also known as the least integer function that gives the smallest integer greater than or equal to x.
For example : For x= 1.5
y = [1.5] =2
For x= 3.64
y = ⌊3.64⌋=4
The given function :
Then, for x= 5.9 , we have
[since [3.9]=4 (least integer function)]
Therefore, the value of f(5.9) is 12
The value of the function f(5.9) will be 12. The correct option is D.
What is a function?In mathematics, a function is a rule that assigns a unique output value to each input value in a specified domain. A function is often denoted by a letter such as f, and we write f(x) to represent the output value associated with an input value x.
We know that the ceiling function y = [x] is also known as the least integer function that gives the smallest integer greater than or equal to x.
For example: For x= 1.5
y = [1.5] =2
For x= 3.64
y = ⌊3.64⌋=4
The given function :
Then, for x= 5.9, we have
F[3.9]=4 (least integer function)]
Therefore, the value of f(5.9) is 12.

If sally invests $400 into the Bank of Reyonds that offers her a 6% interest, compounded monthly, how much money will she have in the bank in 5 years?
Given:
Principal = $400
Rate of interest = 6% compounded monthly
Time = 5 years.
To find:
The amount in the bank after 5 years.
Solution:
The formula for amount is:
[tex]A=P\left(1+\dfrac{r}{n}\right)^{nt}[/tex]
Where, P is principal, r is the rate of interest, n is the number of time interest compounded in an year and t is the number of year.
Interest compounded monthly. So, [tex]n=12[/tex].
Putting [tex]P=400, r=0.06, n=12[/tex] and [tex]t=5[/tex], we get
[tex]A=400\left(1+\dfrac{0.06}{12}\right)^{12(5)}[/tex]
[tex]A=400\left(1+0.005 \right)^{60}[/tex]
[tex]A=400\left(1.005 \right)^{60}[/tex]
[tex]A\approx 539.54[/tex]
Therefore, the amount of money in the bank after 5 years is $539.54.
