WILL MARK BRAINLIEST -The pH scale measures how acidic or basic a substance is. Lemon juice is said to have a pH of less than 4 and greater than 1.5. Model the normal range of pH values of lemon juice, using a compound inequality.


A) 1.5 > x > 4

B) 1.5 < x < 4 C)1.5 ≤ x ≤ 4

D) 1.5 ≥ x ≥ 4

Answer:

60.79 square yards.

Step-by-step explanation:

d = 2r; d = 8.8.

8.8 = 2r

r = 8.8 / 2

r = 4.4 yards.

Since we now have the radius, we can find the area of the circle, which can be found using πr^2, or 3.14 * r^2.

4.4^2 * 3.14 = 19.36 * 3.14 = 60.7904.

Since the question tells us to round to the nearest hundredth, our final answer will be 60.79 square yards.

Hope this helps!

Answer:

The answer to your question is 17.65

Answer: 17.65%

Step-by-step explanation:

X/100 = 15/85 (cross multiplication)

(100*15)/85 = 17.65%

(This helps: %/100 = is/of (cross multiplication)

Answer:

b. -14

Step-by-step explanation:

x is now 3

so -5(3)+1 = -14

Answer:

Use the given functions to set up and simplify f(−4).

14

Step-by-step explanation:

Plug x + h into the function f and simplify to find f(x + h). Now that you have f(x + h), find f(x + h) - f(x) by plugging in f(x + h) and f(x) and simplifying. Plug your result from step 2 in for the numerator in the difference quotient and simplify.

Given function:

The function is plotted and it is below.

The graph of the function f(x) = | (x/2) - 2 | is attached with the answer the lines of the function meet at point 4 at the x-axis.

A graph is the representation of the data on the vertical and horizontal coordinates so we can see the trend of the data.

The graph of the function f(x) = | (x/2) - 2 | is attached with the answer the lines of the function meet at point 4 at the x-axis.

Therefore graph of the function f(x) = | (x/2) - 2 | is attached with the answer the lines of the function meet at point 4 at the x-axis.

Step-by-step explanation:

Answer: celsius = 5/9 (Fahrenheit - 32)

Step-by-step explanation:

Here, you want to start by looking at the fraction they give you. They say that the degrees celsius (C) are going to be equal to five ninths of (something.)

So, right now, your equation should look like this: C = 5/9 (?) because of stands for multiplication.

Next, you want to figure out what that something is. According to the reading, it'll be the degrees Fahrenheit (F) minus 32. So your something is going to look like this: (F-32)

You know that the equation is C = 5/9 (F - 32) and not C = 5/9 F - 32, because if the 32 were outside the parentheses, the prompt would be written "the temperature in degrees celsius is thirty two less than five ninths of the temperature in degrees Fahrenheit." Instead, the number 32 is explicitly included as part of the number that's being multiplied.

I hope that makes sense!

Answer:

  $9.00

Step-by-step explanation:

The simple interest formula can be used.

  I = Prt . . . . . interest on principal P invested at rate r for t years

  I = ($1200)(0.06)(1/8) = $9.00

The simple interest Xander would earn is $9.00.

Justification: the interest is computed using the appropriate formula.
