Answer:
a) ◇G = ◇H - T◇S wiĺl be negative.
b) It will be a spontaneous reaction.
Explanation:
As ◇H is less than 0 and T◇S is greater than 0 so if we put it in the equation we would get the negative maximum result. And when the energies are with negative sign they are said to be spontaneous.

Teresita worked part-time for 2 weeks in a pharmacy. During the second week, she worked 13 times the
number of hours that she worked during the first week. If she worked a total of 25 hours during the 2-week
period, how many hours did Teresita work during the second week?
1.8
2.10
3.12
4.15
Option 4 is correct, Teresita worked 15 hours during the second week.
Given that Teresita worked [tex]1\frac{1}{2}[/tex] times the number of hours during the second week.
Therefore, she worked 1.5x hours during the second week.
The total number of hours she worked during the two weeks is given as 25.
So we can set up the equation:
x + 1.5x = 25
Combining like terms, we have:
2.5x = 25
Dividing both sides of the equation by 2.5, we get:
x = 25/2.5
x = 10
Therefore, Teresita worked 10 hours during the first week.
To find the number of hours she worked during the second week, we can substitute this value back into the equation:
1.5x = 1.5 × 10
= 15
Therefore, Teresita worked 15 hours during the second week.

What is the value of x that makes L1 || L2? please help!! A. 18 B. 12 C. 10 D. 6
Answer:
x = 18
Step-by-step explanation:
Because the 2 lines are parallel we can use same side interior theorem to find x
This would mean the equation is 6x + 30 + 2x + 6 = 180
When you solve that this would be 18
Answer:
x = 18
Step-by-step explanation:
→ Utilise the fact that interior angles add up to 180
6x + 30 + 2x + 6 = 180
→ Simplify
8x + 36 = 180
→ Minus 36 from both sides to isolate 8x
8x = 144
→ Divide both sides by 8 to isolate x
x = 18
Find an equation of the line passing through the pair of points. Write the equation in the form Ax+By = C.
(-4,7), (-5,-2)
Choose the equation of the line in the form Ax + By = C.
Answer:
-9x + y = 43
Step-by-step explanation:
We can put the equation into y = mx + b form first, then change it to Ax + By = C
First, we can find the slope by doing rise/run (y2 - y1) / (x2 - x1)
(-2 - 7) / (-5 + 4)
-9/-1 = 9
We can put this into the equation y = mx + b, along with another point, to find b:
y = mx + b
7 = 9(-4) + b
7 = -36 + b
43 = b
Now, we know the equation will be y = 9x + 43, and we can rearrange this:
Subtract 9x from both sides:
-9x + y = 43 will be the equation of the line

What is the range of the function shown in the graph below? answer type: interval, all real values except one, all real values except two, all real numbers
Interval:
The Range of f(x) → Range ∈ [- 4, ∞).
We have a graph of a function f(x) given.
We have to determine the range of f(x).
What is Domain and Range of any function?The domain of a function f(x) is the set of all values for which the function is defined, and the range of the function is the set of all values that f takes.
According to the question -
We can see that the function is defined for all values of x (assuming that the graph will continue after the arrows at the top). Hence, the domain of f(x) will be set of all real numbers.
Now, the graph curves back after reaching a minimum value of -4. Therefore, the set of all possible values f(x) takes belongs to the set
[-4, ∞).
Hence, the Range of f(x) → Range ∈ [- 4, ∞)

Find the perimeter and area of the shaded region.
Answer:
Perimeter of the shaded region= 22/7cm
Area = 36.48 cm²
Step-by-step explanation:
First of all for the perimeter.
The radius of the arc is 8cm
At an angle of 90°
Perimeter of of the shape is perimeter of the the 2 arc
The both arc are equal so let's determine the perimeter of one first.
Perimeter of the arc= 2πr*(90/360)
Perimeter of the arc= 2*22/7*1/4
Perimeter of the arc= 11/7 cm
Perimeter of the shades region= 2*11/7
Perimeter of the shaded region= 22/7cm
Area of the sector = πr²*(90/360)
Area of the sector= 50.24cm²
Area of non sector= 64-50.24
= 13.76
But non sector is two
Area of non sector= 2*13.76
= 27.52
Area of the shaded region = area of the square -(area of non sector)
= 64-27.52
= 36.48 cm²

The volume of a sphere is [tex]\frac{1}{162} \pi[/tex] cubic meters. What is the length of the sphere’s radius? In your final answer, include all of your calculations.
Answer:
The radius is 1/6 m
Step-by-step explanation:
The volume of a sphere is given by
V = 4/3 pi r^3
1/162 * pi = 4/3 pi r^3
Divide each side by pi
1/162 = 4/3 r^3
Multiply each side by 3/4
3/4 *1/162 =3/4* 4/3 r^3
1/216 = r^3
Take the cube root of each side
(1/216)^ 1/3 = (r^3)^1/3
1/6 = r
The radius is 1/6 m

At the same time, Sam and Fred who are 168 miles apart begin moving toward each other. Find the number of hours before they meet if Sam runs 12 mph and Fred runs 9 mph.
Answer: 8 hours
Step-by-step explanation:
Let x be the time before they meet ( in hours)
Speed of Sam = 12 mph
Sped of Fred = 9 mph
Distance = Speed × time
Distance covered by Sam in x hours = 12x
Distance covered by Fred in x hours = 9x
(Distance) (rate1) (time1) (rate2) (time2)
Total distance between them: 168 = 12 x + 9 x
[tex]\Rightarrow\ 168= 21x\\\\\Rightarrow\ x=\dfrac{168}{21}=8[/tex]
Hence, the number of hours before they meet if Sam runs 12 mph and Fred runs 9 mph. = 8

Four letters are selected at random with replacement from the word MATHCOUNTS. What is the probability that the letters in the order they are selected will form the word MATH?
So "MATHCOUNTS" has 10 letters.
And "MATH" has 4 letters.
So the probability of you getting the letters "M" "A" "T" "H" is 4/10 or 2/5.
But it has to be in order...
There are 32 ways you can arrange the 4 letters. There is only 1 way you can write "MATH"
So 1/32 probability of 2/5 is 2/160 or 1/80
The probability of getting the word MATH is 1/80
What is Probability ?The study of likeliness of an event to happen is probability .
It is given that
Total letters in MATHCOUNTS : 10 letters.
Total chances of getting letter M , A , T , H is 4
Probability of getting the letters M , A , T , H is 4/10
= 2 /5
The probability of getting the word MATH is 1
And the total number of ways the letters can be arranged is 2⁴
