The first year, they found the chloride concentration changed by −135 mg/L . It is estimated that the chloride concentration will change −2115 mg/L the next year.
What is the total change that will likely occur in 2 years?
Enter your answer as a simplified mixed number in the box.
______mg/L
Answer:
The total change that will likely occur in 2 years is [tex]=-3\frac{2}{3}[/tex] mg/L
Step-by-step explanation:
Given : The first year, they found the chloride concentration changed by [tex]-1\frac{3}{5}[/tex] mg/L .
It is estimated that the chloride concentration will change [tex]-2\frac{1}{15}[/tex] mg/L the next year.
To find : What is the total change that will likely occur in 2 years?
Solution :
The chloride concentration changed by [tex]-1\frac{3}{5}=-\farc{8}{5}[/tex] mg/L in first year.
The chloride concentration will change [tex]-2\frac{1}{15}=-\frac{31}{15}[/tex] mg/L the next year.
The total change that will likely occur in 2 years is
[tex]=-\frac{8}{5}+(-\frac{31}{15})[/tex]
[tex]=\frac{-24-31}{15}[/tex]
[tex]=\frac{-55}{15}[/tex]
[tex]=\frac{-11}{3}[/tex]

if g(x) = 2x-1 and h(x) = sqrt x find (g o h)(9)
Answer:
(g o h)(9) =5
Step-by-step explanation:
Given :[tex]g(x) = 2x-1[/tex]
[tex]h(x) = \sqrt{x}[/tex]
To Find: (g o h)(9)
Solution:
[tex]g(x) = 2x-1[/tex]
[tex]h(x) = \sqrt{x}[/tex]
To find (g o f)(x)=g(h(x))
[tex]g(h(x)) = 2\sqrt{x}-1[/tex]
Now substitute x = 9
[tex]g(h(9)) = 2\sqrt{9}-1[/tex]
[tex]g(h(9)) = 2(3)-1[/tex]
[tex]g(h(9)) = 6-1[/tex]
[tex]g(h(9)) = 5/tex]
(g o h)(9) =5
Hence the value of (g o h)(9) is 5

Given 3x <9 Choose the solution set
Answer:
[tex]x<3[/tex] or [tex](-\infty,3)[/tex]
Step-by-step explanation:
We have been given an inequality [tex]3x<9[/tex]. We are asked to find the solution set for our given inequality.
We will divide both sides of our inequality by 3 to solve for x.
[tex]\frac{3x}{3}<\frac{9}{3}[/tex]
[tex]x<3[/tex]
Therefore, the solution for our given inequality will be all values of x less than 3, that is [tex](-\infty,3)[/tex] in interval notation.
Each block in Ton's neighborhood is 2/3 mile long. If he walks 4 1/2 blocks,how far dose he walk?
Ton walks a total of 3 miles when he covers 4 1/2 blocks in his neighborhood, where each block is 2/3 mile long.
If Ton walks 4 1/2 blocks and each block in his neighborhood is 2/3 mile long, we can calculate the total distance he walks by multiplying the number of blocks by the length of each block. To find the distance Ton walks, you perform the following calculation:
First, convert the mixed number 4 1/2 into an improper fraction: 4 1/2 = (4 imes 2 + 1) / 2 = 9/2.
Multiply the improper fraction representing the blocks walked (9/2 blocks) by the fraction that represents the length of each block (2/3 mile): (9/2)imes (2/3) = 9/2 imes 2/3.
Simplify the multiplication by canceling out common factors: 9/2 imes 2/3 = (9 imes 2) / (2 imes 3) = 9/3 = 3 miles.
Therefore, Ton walks a total distance of 3 miles.
express this decimal as a fraction.

a chair is placed several feet from a fire in a fireplace the fireplace has a glass screen the side of the chair facing the fireplace gets warm because of conduction convection or radiation??? will give brainliest
The warmth felt by the chair facing the fireplace is primarily due to radiation, where heat from the fire emits infrared radiation that is subsequently absorbed by the chair surface.
Explanation:The side of the chair facing the fireplace gets warm primarily because of radiation. Radiation is the process whereby heat is transferred through electromagnetic waves. In this case, heat from the fire emits infrared radiation, which travels through the air until it strikes the surface of the chair and is absorbed, causing the chair to warm up.
In heat transfer, there are three main methods: conduction, convection, and radiation.
Conduction is the process whereby heat is transferred through direct contact of objects, while convection involves the movement of warm air or fluids. Conduction and convection play minor roles in this scenario -- conduction would occur if the chair were in contact with the warm air, and convection is mainly responsible for heat transfer within the air of the room.

luisa sells stuffed animals. she sells a stuffed elephant for $34.90, and the sales tax is 6% of the sale price. about how much is the sales tax on the elephant?
To find the sales tax on a $34.90 item with a 6% tax rate, convert 6% to a decimal (0.06) and multiply by the item cost, resulting in a sales tax of about $2.09.
Luisa sells a stuffed elephant for $34.90 and needs to calculate the sales tax, which is 6% of the sale price. To find the sales tax, first convert the percent to a decimal by dividing by 100, which makes it 0.06. Then multiply the sale price by this decimal:
$34.90 x 0.06 = $2.094
Now, you need to round $2.094 to the nearest penny, which is $2.09. Therefore, the amount of sales tax on the stuffed elephant is approximately $2.09.

Answer:
its -2c
Step-by-step explanation:
Pedro buys 4 books at the fair for $7 each. Pedro hands the cashier 3 ten dollar bills. how much change would he receive? write an equation to solve. use c to represent the unknown.
The problem involves calculating the change received when Pedro buys four books at $7 each and pays with $30. The equation to solve this is c = $30 - $28. Therefore, Pedro receives $2 change.
Explanation:The subject of this question is a straightforward mathematics problem involving buying books and receiving change. We know that Pedro buys 4 books that each cost $7 and that he gives the cashier $30. To find out the change, represented as c , Pedro will get, we first figure out the total cost of the books: 4 books x $7 per book equals $28. Pedro pays with $30 so the calculation for the change would be: $30 (the amount Pedro paid) - $28 (the total cost of the books). This gives us the equation c = $30 - $28. Therefore, Pedro would receive $2 in change.

Pedro buys 4 books for $28 and pays with $30, so he would receive $2 in change. The equation to represent this is: c = $30 - $28.
To calculate the change Pedro receives, we can set up an equation where c represents the unknown change. Pedro buys 4 books at $7 each, so the total cost of the books is 4 books x $7/book = $28. He hands the cashier 3 ten dollar bills, which equals $30. The equation to find the change is then:
c = $30 - $28
Solving this equation, we get:
c = $2
So, Pedro would receive $2 in change after buying the books.
