\text{Josefina started to solve for x in the equation}\\

3.5 = 1.9-0.8|2x- 0.6|

\text{using the steps below:}

3.5 = 1.9-0.8|2x-0.6|

1.6 = -0.8|2x-0.6|

-2 = |2x-0.6|

\text{Josefina stop at Step 3 because on the right side we have mod. }\\ \text{and this mod returns only positive values}\\ \\

\text{But on the left hand side , we have negative value.}\\ \text{Hence False, it mean no solution exists}\\

One of the fastest times ever recorded for the 50 yard dash is 5.2 seconds. The following expression
igomit [66]

Answer:

Option (1)

Step-by-step explanation:

Fastest time recorded = 50 yards dash is 5.2 seconds.

To convert this time into the rate of miles per hour, expression to be used will be,

\frac{50\text{yd}}{5.2\text{sec}}\times \frac{3\text{ft}}{1\text{yd}}\times \frac{1\text{ mile}}{5280\text{ft}}\times \frac{60\text{sec}}{1\text{min}}\times \frac{60\text{min}}{1\text{hr}}

By cancelling common term in the numerator and denominator in the given expression we will get the answer in miles per hour.

Therefore, Option (1) will be the correct option.

The approximate molar concentration of several chemicals are given. Find the pH of each use the calculator and round to the near
svet-max [94.6K]

Explanation:

Formula to calculate pH of a chemical or solution is as follows.

                    pH = -log [H^{+}]

Therefore, calculate the pH of given chemicals as follows.

1). Oven cleaner

              pH = -log [H^{+}]

                    = -log [10^{-13}]

                    =  13

2). Water

               pH = -log [H^{+}]

                     = -log [7 \times 10^{-7}]

                     = 6.15

3). Blood

               pH = -log [H^{+}]    

                     = -log [4 \times 10^{-8}]

                     = 7.40

4). Vinegar

                pH = -log [H^{+}]    

                      = -log [63 \times 10^{-4}]

                      = 2.20

The speed, s, of the current in a certain whirlpool is modeled by s=300/d, where d is the distance from the center of the whirlp
Ivan

Answer:

The answer is C. As you move closer to the center of the whirlpool, the speed of the current approaches infinity.

This means the closer you get, the faster you go, and the further the distance is the slower the speed. Hope this helps!

(Btw I got this right on the test)
