What is the ph of a koh solution that has [h ] = 1.87 × 10–13 m? round to the nearest tenth. what is the poh of a koh solution that has [oh–] = 5.81 ×10–3m? round to the nearest hundredth. what is the ph of a solution of nacl that has [h ] = 1.00 × 10–7 m? round to the nearest hundredth.
The ph and poh values were calculated using the formula.
It is given that
[H⁺] of KOH solution = [tex]1.87*10^{-13}[/tex]
What is the ph and poh formula?[tex]ph = -log[H^{+} ][/tex]
[tex]poh = -log[OH^{-} ][/tex]
So, ph of KOH solution = [tex]-log[1.87*10^{-13} ][/tex]
The ph of KOH solution = 12.72
Similarly, poh of a KOH solution that has [OH⁻] = 5.81 ×10–3m is 2.24.
The ph of NaCl solution that has [H⁺] = 1.00 × 10–7m is 7.
Thus, the ph and poh values were calculated using the formula.

Given the functions f(x) = 10x 25 and g(x) = x 8, which of the following functions represents f[g(x)] correctly? f[g(x)] = 10x 33 f[g(x)] = 10x2 33 f[g(x)] = 10x 105 f[g(x)] = 10x2 105.

Consider all six-digit numbers that can be created from the digits 0-9 where the first and last digits must be odd and no digit can repeat. What is the probability of choosing a random number that starts with 9 from this group? Enter a fraction or round your answer to 4 decimal places, if necessary
Using the Fundamental Counting Theorem, it is found that there is a 0.2 = 20% probability of choosing a random number that starts with 9 from this group.
What is the Fundamental Counting Theorem?It is a theorem that states that if there are n things, each with [tex]n_1, n_2, \cdots, n_n[/tex] ways to be done, each thing independent of the other, the number of ways they can be done is:
[tex]N = n_1 \times n_2 \times \cdots \times n_n[/tex]
In this problem, we have that:
The first and last digit have to be odd, hence [tex]n_1 = 5, n_6 = 4[/tex].The others cannot repeat, hence: [tex]n_2 = 8, n_3 = 7, n_4 = 6, n_5 = 5[/tex].Then, the total number is:
N = 5 x 4 x 8 x 7 x 6 x 5 = 33600.
Starting with 9, we have that:
The first digit is 9, the last digit has to be an odd which is not 9, hence [tex]n_1 = 1, n_6 = 4[/tex].The others cannot repeat, hence: [tex]n_2 = 8, n_3 = 7, n_4 = 6, n_5 = 5[/tex].Then:
N9 = 1 x 4 x 8 x 7 x 6 x 5 = 6720.
A probability is given by the number of desired outcomes divided by the number of total outcomes, hence:
p = N9/N = 6720/33600 = 0.2.
0.2 = 20% probability of choosing a random number that starts with 9 from this group.

[tex]2 \times area \div height \:[/tex]
Step-by-step explanation:
the answer is 5
Answer:
JH=16
Step-by-step explanation:
Hi there!
We are given ΔHIJ, where HI is parallel to KL, and that JK=10, JI=40, and JL=25
We want to find JH
We can use something called the Triangle Proportionality Theorem to help us find JH
The Triangle Proportionality Theorem essentially states that if there is a line parallel to one of the sides of a triangle that intersects the other 2 sides of that triangle, then that segment divides those sides proportionally
In other words, KL is parallel to HI and intersects both HJ and JI, and JK, JH, JL, and JI create a proportion, which is [tex]\frac{JK}{JH} =\frac{JL}{JI}[/tex]
We can substitute the values that we know into that equation
[tex]\frac{10}{JH} =\frac{25}{40}[/tex]
We can simplify 25/40 to 5/8.
[tex]\frac{10}{JH} =\frac{5}{8}[/tex]
Now we can cross multiply (use the means-extreme theorem)
Multiply 10 and 8 together, and set that equal to 5 times JH
80 = 5JH
Divide both sides by 5
16=JH
Hope this helps!

two angles? Choose all that apply.
44
81°
11°
28°
Answer:
28°
Step-by-step explanation:
In an isosceles triangle, by definition two of the three sides of the triangle are equal to one another. Therefore, the angles opposite to these sides must also be equal. And considering the Triangle Sum Theorem, the angles of a triangle must add up to 180 degrees, the angle that measures 124 degrees cannot be be equal to another angle due to the fact that the sum of them would exceed 180. Therefore let x be the angle:
124+2x=180
2x=56x=28°

Question :-
Find the Area of Parallelogram whose Height is 5 cm and the Base is 8 cm .Answer :-
Area of Parallelogram is 40 cm² .Explanation :-
As per the provided information in the given question, we have been given that the Height of the Parallelogram is 5 cm . Its Base is given as 8 cm . And, we have been asked to calculate the Area of Parallelogram .
For calculating the Area , we will use the Formula :-
[tex] \bigstar \: \: \: \boxed{ \sf{ \: Area \: _{Parallelogram} \: = \: Base \: \times \: Height \: }} [/tex]
Therefore , by Substituting the given values in the above Formula :-
[tex] \dag \: \: \: \sf {Area \: _{Parallelogram} \: = \: Base \: \times \: Height} [/tex]
[tex] \longmapsto \: \: \sf {Area \: _{Parallelogram} \: = \: 8 \: \times \: 5} [/tex]
[tex] \longmapsto \: \: \bf {Area \: _{Parallelogram} \: = \: 40} [/tex]
Hence :-
Area of Parallelogram = 40 cm² .[tex] \underline {\rule {180pt} {4pt}} [/tex]
Four friends share the profit of a lawn care service equally. the friends charge $45 per lawn and spend $30 of their total earnings on gasoline for the lawnmowers each week. which inequality can be used to find m, the number of lawns they need to mow next week so that each person earns at least $275? startfraction 45 m minus 30 over 4 endfraction greater-than-or-equal-to 275 startfraction 45 m over 4 endfraction minus 30 greater-than-or-equal-to 275 startfraction 45 m minus 30 over 4 endfraction less-than-or-equal-to 275 startfraction 45 m over 4 endfraction minus 30 less-than-or-equal-to 275
Inequality can be used to find m will be 45m - 30 ≥ 1100. Inequality is an opinion of an ordering relationship between two digits or algebraic terms,
What is inequality?
inequality is a statement of an order relationship between two numbers or algebraic expressions, such as greater than, greater than or equal to, less than, or less than or equal to.
The amount charged for lawn= $45
"m" is the total number of lawns they move per week. Because they charge $ 45 per lawn, the total amount they will charge for m lawns will be $ 45m.
Every week, they spend $ 30 of their whole earnings on gasoline. As a result, each week's total earnings will be
45m-30
Everybody wants to make at least $275. Because there are four of them, the total they aim to earn is at least
The total amount has to be earned for the four friends=4 x 275 = $ 1100
We need to figure out how many lawns they'll have to move in the following week to earn at least $1100. The equation is as follows:
45m - 30 ≥ 1100
This disparity may be used to find m, the number of lawns they need to mow next week to earn at least $275 for each participant. This can be solved in the following way:
45m ≥ 1130
m ≥ 25.11
We round up the number of lawns to 26 to guarantee they earn at least $ 1100 in total because the number of lawns must be a whole number.
we get m ≥ 26.
Hence inequality can be used to find m will be 45m - 30 ≥ 1100.

The students in Mary’s class sold cookies for a fundraiser this year and last year. This year, the selling price of a box of cookies was $13.25. The price this year represents 6% more than the selling price of each box last year.
Find 6% of 13.25
0.06 x 13.25 = 0.795
Then subtract 0.795 from 13.25 because the price was less last year
13.25-0.795 = 12.455
Rounded up that would be $12.46 last year

Identify the solution to the following inequality: -1/2 (x+3) > x - 3
A. X < 1
B. X > 3
C. X > 1
D. X< 3
Answer:
A
Step-by-step explanation:
- [tex]\frac{1}{2}[/tex] (x + 3) > x - 3 ( multiply both sides by 2 to clear the fraction )
- (x + 3) > 2x - 6 ← distribute parenthesis on left side by - 1
- x - 3 > 2x - 6 ( subtract 2x from both sides )
- 3x - 3 > - 6 ( add 3 to both sides )
- 3x > - 3
divide both sides by - 3, reversing the symbol as a result of dividing by a negative quantity
x < 1
Answer:
A. x<1
Step-by-step explanation:
-1/2 (x+3) > x - 3
(-1/2)x-3/2>x-3
Multiply both sides by 2:
-x-3>2x-6
add both sides by 3:
-x-3+3>2x-6+3
-x>2x-3
minus both sides by 2x
-x-2x>2x-2x-3
