HELP ME PLEASE, ILL GIVE BRAINLIEST TO YOU Each year, the Department of Water Works measures the chloride concentration level in the water. The first year, they found the chloride concentration changed by −1 3/5 mg/L . It is estimated that the chloride concentration will change −2 1/15 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.

Final answer:

Combine like terms by adding or subtracting the coefficients of terms with the same variable and combining constants. The simplified expression is 4b + 2, so the coefficients that go in the boxes are 4 and 2.

Explanation:

To simplify the expression by combining like terms, follow the process of identifying and adding/subtracting like terms. The expression 7b + 4 - 3b - 2 contains both variable terms (containing 'b') and constant terms (just numbers).

Combine like terms:

Combine variable terms: 7b - 3b = 4b.

Combine constant terms: 4 - 2 = 2.

After combining like terms, the simplified expression is 4b + 2.

Therefore, the numbers that go in the boxes are 4 for the coefficient of 'b' and 2 for the constant term.

The number of miles for which the cost of both shuttles is the same is 40.

The slope of the line is the ratio of the rise to the run, or rise divided by the run. It describes the steepness of line in the coordinate plane.

The slope intercept form of a line is y=mx+b, where m is slope and b is the y intercept.

The slope of line passing through two points (x₁, y₁) and (x₂, y₂) is

m=y₂-y₁/x₂-x₁

The charges for two shuttle services are shown in the table.

m=0-10/0.35-0.10

=10/0.25

Ten divided by zero point two five is 10 by one divided by 4.

=40 miles

Hence, the number of miles for which the cost of both shuttles is the same is 40.

The walls of a room need painting. Each of the four walls is 12 ft wide by 8.5 feet tall.

We know that, Area = length [tex]\times[/tex] width.

So, the area of one wall = 8.5 ft [tex]\times[/tex] 12 ft = 102 square feet

Thus, the area of 4 walls = 4 [tex]\times[/tex] 102 = 408 square feet

One gallon of paint covers 75 square feet. We need to find how many gallons of paint will cover 408 square feet.

So, the amount of gallons of paint needed = 408[tex]\div[/tex]75

= 5.44 gallons

So, 5.44 gallons are needed to cover 408 square feet.

To find the number of gallons of paint needed to paint the walls of a square room, calculate the total area of all four walls and divide it by the coverage of one gallon of paint.

To find the total area of all four walls, we need to calculate the area of one wall and then multiply it by four. The area of one wall is the product of its width and height, which is 12 ft x 8.5 ft = 102 ft².

So, the total area of all four walls is 102 ft² x 4 = 408 ft².

Since one gallon of paint covers 75 ft², we divide the total area of all four walls (408 ft²) by the coverage of one gallon of paint (75 ft²) to find the number of gallons needed: 408 ft² ÷ 75 ft² = 5.44 gallons.

Therefore, you will need approximately 5.44 gallons of paint to paint the walls of the square room.

Answer:

796.2

Step-by-step explanation:

a number 1/10 as great as 7962 can be found in two ways the first way is

1) Divide 7962 by 10 we get 796.2

there fore 7962/10= 796.2

second way to get

2) multiply 7962 by 1/10 we again get 796.2

therefore from both the calculation a number 1/10 as great as 796.2

The statement that is true about the graph is The maximum value of g(x) is greater than the minimum value of f(x).

1. "The maximum value of g(x) is greater than the minimum value of f(x)": This is true because the maximum value of g(x) is -10, which is greater than the minimum value of f(x) (which we don't know, but it cannot be lower than -10 based on the given data).

2. "The minimum value of g(x) is less than the maximum value of f(x)": This is true based on the given data, as the minimum value of g(x) is -1, which is less than the maximum value of f(x) (which we don't know, but it cannot be higher than -1 based on the given data).

3. "The minimum value of g(x) is greater than the maximum value of f(x)": This is false based on the given data. The minimum value of g(x) is -1, which is less than the maximum value of f(x) (which we don't know).

4. "The maximum value of g(x) is less than the minimum value of f(x)": This is false based on the given data. The maximum value of g(x) is -10, which is less than the minimum value of f(x) (which we don't know, but it cannot be lower than -10 based on the given data).

The greatest value of g(x) is -1 (the higher number for the g(x) entry in the table), and the minimum value of f(x) is -3 (the lower y/f(x) you may point on the graph). As a result, the maximum value of g(x) exceeds the minimum value of f(x).

The unit rates which will be reasonable for Violet to use to describe how fast the sand is draining from the upper portion to the lower portion of the glass is cubic centimeters per minute.

Explanation:

As the first 2 options gallons per hour and liters per hour, these denote liquid forms. But sand is not liquid that is why it cannot be the answer.

Cubic inches per second is very fast as compared to the small hourglass and the amount of sand that could be present in it. Moreover one side of the hourglass needs to be emptied in 24 hours, so this option is also not possible.

The number is 144.32 whose 97% is 140 ft .

Given,

140 ft is 97 percent of what number .

Here,

Let the number be x .

Forming the equation,

97% of x = 140

97/100 of x = 140

x = 140 * 100/97

x = 140000/97
