Converting a decimal to a mixed number is very simple when you get the hang of it. Since 8 is before the decimal, that is your number in the mixed number. For the fraction part, it's 77/100. The denominator is 100 because when you count the decimal places, it goes to hundredths. 77/100 is already in simplest form, so your final answer is 8 77/100.

Point Tis on line segment SU. Given TU = 4x + 1, SU = 8, and ST = 3x,
Harrizon [31]

Answer:

5 units

Step-by-step explanation:

If point T is on the line segment SU, then ST + TU = SU.

Given

TU = 4x + 1

SU = 8

ST =  3x

To get TU, we need to get the value of x first. To get x, we will substitute the given parameters into the formula;

3x+4x+1 = 8

7x+1 = 8

subtract 1 from both sides

7x+1-1 = 8-1

7x = 7

divide both sides by 7

7x/7 = 7/7

x = 1

Substitute x = 1 into the length TU

Since TU = 4x+1

TU = 4(1)+1

TU = 5

Hence the numerical length of TU is 5 units

2. The alkalinity of a fluid (pH) can be modeled in terms of its hydrogen ion concentration (H+, measured in moles/liter) of the
nataly862011 [7]

Given the equation:

pH=-log\mleft(H^+\mright)

You know that a lab technician finds that a sample of fluid has this pH:

pH=4.5

Then, in order to find the hydrogen ion concentration of the fluid, you need to follow these steps:

1. Substitute the pH given in the exercise into the equation:

4.5=-log(H^+)

Multiply both sides by -1:

-4.5=\log (H^+)

2. Solve for:

H^+

Remember that, by definition:

\log _b\mleft(c\mright)=a\Rightarrow b^a=c

In this case, you can identify that:

\begin{gathered} a=-4.5 \\ b=10 \\ c=H^+ \end{gathered}

Hence, substituting values and simplifying, you get:

\begin{gathered} b^a=c \\ 10^{-4.5}=H^+ \\ H^+=0.00003162278\text{ }\frac{moles}{liter} \end{gathered}

Therefore, the answer is:

H^+=0.00003162278\text{ }\frac{moles}{liter}
