a principal that will amout to 150000 for 8 years at 9/1/2 %
The principal amount is 85227.27 and the interest is 64772.73.
Solution:
Given:
Amount (A)= 150000
Number of years (n)= 8
Rate of interest (r)= [tex]9\frac{1}{2}\%=\frac{19}{2}\%[/tex]
To find: The principal (P)
We know that the principal is the sum of amount and interest. That is, [tex]\bold{P+I=A}[/tex]
This can be written as [tex]\bold{I=A-P \rightarrow(1)}[/tex]
The formula of simple interest is [tex]\bold{I=\frac{Pnr}{100} \rightarrow(2)}[/tex]
On equating (1) and (2) we get,
[tex]\Rightarrow\bold{A-P=\frac{Pnr}{100}}[/tex]
On substituting the values we get,
[tex]\Rightarrow\bold{150000-P=\frac{P\times8\times19}{100\times2}}[/tex]
On solving we get,
[tex]\bold{\Rightarrow 150000-P=0.76P}[/tex]
On grouping the like terms together we get,
[tex]\bold{\Rightarrow 150000=0.76P+P}[/tex]
[tex]\bold{\Rightarrow 150000=1.76P}[/tex]
[tex]\bold{\Rightarrow P=\frac{150000}{1.76}}[/tex]
[tex]\bold{\Rightarrow P=85227.2727\approx85227.27}[/tex]
If principal is 85227.27, then the interest will be [tex]\bold{I=150000-85227.27\rightarrow64772.73}[/tex]

Answer:
The Three expressions that have a sum or difference of 3 /4 .
B . 11/12 − 1/6
C. 3/5 + 3/20
E . 2/3 + 1/12
Step-by-step explanation:
The Three expressions that have a sum or difference of 3 /4 .
are
B . 11/12 − 1/6
[tex]\dfrac{11}{12}-\dfrac{1}{6}=\dfrac{11}{12}-\dfrac{1\times 2}{6\times 2}\\\\\dfrac{11}{12}-\dfrac{1}{6}=\dfrac{11}{12}-\dfrac{2}{12}=\dfrac{11-2}{12}=\dfrac{9}{12}=\dfrac{3}{4}[/tex]
Therefore,
[tex]\dfrac{11}{12}-\dfrac{1}{6}=\dfrac{3}{4}[/tex]
C. 3/5 + 3/20
[tex]\dfrac{3}{5}+\dfrac{3}{20}=\dfrac{3\times 4}{5\times 4}+\dfrac{3}{20}\\\\\dfrac{3}{5}+\dfrac{3}{20}=\dfrac{12}{20}+\dfrac{3}{20}=\dfrac{15}{20}=\dfrac{3}{4}[/tex]
Therefore,
[tex]\dfrac{3}{5}+\dfrac{3}{20}=\dfrac{3}{4}[/tex]
E . 2/3 + 1/12
[tex]\dfrac{2}{3}+\dfrac{1}{12}=\dfrac{2\times 4}{3\times 4}+\dfrac{1}{12}\\\\\dfrac{3}{5}+\dfrac{3}{20}=\dfrac{8+1}{12}=\dfrac{9}{12}=\dfrac{3}{4}[/tex]
Therefore,
[tex]\dfrac{2}{3}+\dfrac{1}{12}=\dfrac{3}{4}[/tex]
Expressions B (11/12 − 1/6), C (3/5 + 3/20), and E (2/3 + 1/12) each simplify to a sum or difference of 3/4 after finding a common denominator and simplifying the fractions.
Explanation:To find 3 expressions that have a sum or difference of 3/4, let's evaluate each option given:
A. 1/2 + 2/4 simplifies to 1/2 + 1/2, which equals 2/2 or 1. This does not equal 3/4.B. 11/12 − 1/6 can be calculated by finding a common denominator, which would be 12. So, 1/6 is equivalent to 2/12. Thus, 11/12 − 2/12 equals 9/12, which simplifies to 3/4.C. 3/5 + 3/20 requires us to find a common denominator, which would be 20. So, 3/5 is equivalent to 12/20. Thus, 12/20 + 3/20 equals 15/20, which simplifies to 3/4.D. 7/8 − 1/2 requires a common denominator, which would be 8. So, 1/2 is equivalent to 4/8. Thus, 7/8 − 4/8 equals 3/8. This does not equal 3/4.E. 2/3 + 1/12 requires a common denominator, which would be 12. So, 2/3 is equivalent to 8/12. Thus, 8/12 + 1/12 equals 9/12, which simplifies to 3/4.Therefore, the three expressions that have a sum or difference of 3/4 are B, C, and E.
A square table has an area of "2116" square inches. A tablecloth hang 3 inches over each end of the table, What is the area of the part of the tablecloth that hangs over the table?
The area of the part of the tablecloth that hangs over the table is 285 square inches
Step-by-step explanation:
In order to find the area of table cloth that hangs over the table, we have to find the area of table and the total area of table cloth.
Given
Area of table = [tex]A_t = 2116\ in^2[/tex]
To find the side of the square
[tex]A_t = s^2\\s^2 = 2116[/tex]
Taking Square root on both sides
[tex]\sqrt{s^2} = \sqrt{2116}\\s = 46\ inches[/tex]
When the table cloth is hanged, 3 inches are left to hang over this means that the side will now be: 46+3 = 49 inches
The area of table cloth = [tex]A_c = 49*49 = 2401\ in^2[/tex]
The area of table cloth that will be hung over the table is:
[tex]A_c-A_t\\= 2401-2116\\= 285\ in^2[/tex]
Hence,
The area of the part of the tablecloth that hangs over the table is 285 square inches

19. A county government says that a safe level of chlorine in a hot tub is within 1.75 ppm of 3.25 ppm.
a. Write and solve an absolute value inequality to represent this situation
b. A life guard measures the chlorine level in the pool and finds it is 1.0ppm. Should he add more chlorine? Explain.
To ensure safe chlorine levels in the pool, the inequality |Cl - 3.25| ≤ 1.75 must be met, representing levels between 1.50 ppm and 5.00 ppm. The lifeguard found the level at 1.0 ppm, which is below the safe range, so more chlorine needs to be added.
Explanation:Absolute Value Inequality for Chlorine Levels:
The county government specifies that a safe level of chlorine is within 1.75 ppm of 3.25 ppm. We can express this using an absolute value inequality to represent the acceptable range for the chlorine levels: |Cl - 3.25| ≤ 1.75. This represents that the chlorine level (Cl) can be at most 1.75 ppm above or below 3.25 ppm.
To solve this inequality, we consider both the upper and lower bounds:
Therefore, the chlorine level must be between 1.50 ppm and 5.00 ppm.
Analysis of the Chlorine Level Measurement:
As the lifeguard measures the chlorine level in the pool at 1.0 ppm, it falls below the acceptable range established by the inequality. Consequently, the lifeguard should add more chlorine to bring the concentration up to within the safe range, specifically, at least to the minimum safe level of 1.50 ppm.

What is algebra ?
Algebra is the branch that deals with various symbols and the arithmetic operations such as addition , subtraction , etc.
As per the questions ;
Jones family has a trip of 3 days.
Let's assume they travel distance of x miles on first day.
Distance they will travel on second day = x + 200 miles
Distance they will travel on third day = x - 75 miles
Total distance of trip = 1058 miles
i.e.,
x + (x + 200) + (x - 75) = 1058 miles
3x + 125 = 1058
3x = 1058 - 125
3x = 933
x = 311 miles
So , they travel for a distance of 311 miles on day 1.
&
On day 2 ;
= 311 + 200
= 511 miles
&
on day 3 ;
= 311 - 75
= 236 miles
Thus , Jones family will travel for 311 miles on day 1 , 511 miles on day 2 and 236 miles on day 3.

which of the statements is true for the two equations below?
Equation A: 6+3x=3x-3
Equation B: 2(4x-1)=8x-2
A.Equation A has no solution and Equation B has an infinite number of solutions.
B.Equation A has an infinite number of solutions and Equation B has no solution.
C.Equation A and Equation B have an infinite number of solutions.
D. Equation A and Equation B have no solution.
Equation A:
6 + 3x = 3x - 3
This equation has no solution, no matter what number you plug into the equation, it will never = each other
[if you tried simplifying more]
9 + 3x = 3x (added 3 on both sides, then subtracted 3x on both sides)
9 = 0
Equation B:
2(4x - 1) = 8x - 2 Distribute/multiply 2 into (4x - 1)
(2)4x - (2)1 = 8x - 2
8x - 2 = 8x - 2
This will have an infinite number of solutions because whatever number you plugged in, they would always = each other since they are the same on both sides of the equation
[simplified]
8x = 8x (add 2 on both sides, then divide 8 on both sides)
x = x
Your answer is A
Equation A has no solution and Equation B has an infinite number of solutions.
Explanation:The correct answer is D. Equation A and Equation B have no solution. Let's analyze each equation:
For Equation A, we can combine like terms and simplify it to:
6 + 3x = 3x - 3
6 = -3
Since 6 is not equal to -3, Equation A has no solution.
For Equation B, we distribute 2 to the terms inside the parentheses:
2(4x - 1) = 8x - 2
8x - 2 = 8x - 2
Both sides of the equation have the same expression, so Equation B is an identity. It means that for any value of x, both sides will always be equal. Therefore, Equation B has an infinite number of solutions.
Hence, the correct answer is D. Equation A and Equation B have no solution.

How to solve c/-9+6=14
Answer:
c/9+6=14
9c=14-6
9c=8
c=8:9
c=1.125
Step-by-step explanation:
After solving this c/(-9+6) = 14 equation we get c = -42. To solve the equation c/(-9+6) = 14, we first simplify the expression inside the parentheses. (-9 + 6) equals -3.
Therefore, the equation becomes c/(-3) = 14. To isolate the variable c, we multiply both sides of the equation by -3. This gives us c = 14 * (-3), which simplifies to c = -42.
Hence, the solution to the equation is c = -42. Remember to follow the order of operations (PEMDAS/BODMAS) when simplifying expressions and be cautious when dealing with negative signs in equations.

The company should sell each widget for $28.25, to the nearest cent.
To maximize profit, we need to find the vertex of the parabola represented by the profit equation y = -2x^2 + 113x - 497. Since the coefficient of x^2 is negative, the parabola opens downwards, and the vertex represents the maximum point. The x-coordinate of the vertex of a parabola in the form of y = ax^2 + bx + c can be found using the formula -b/2a.
For the equation y = -2x^2 + 113x - 497, a = -2 and b = 113. Plugging these values into the formula gives us: x = -113 / (2 × -2) = -113 / -4 = 28.25. Therefore, to maximize profit, the company should sell each widget for $28.25, to the nearest cent.

If the base angles of an isosceles triangle each measure 37° then the vertex angle measures 106°
Answer:
the given statement is true.
Step-by-step explanation:
i) It is given that the base angles of an isosceles triangle each measure 37°.
ii) Adding the values of the base angles is = 37° + 37° = 74°
iii) from the property of triangles we know that the sum of all the angles in a triangle is equal to 180°
iv) let the vertex angle be = y°
v) Therefore we can say from ii), iii) and iv) above that
74° + y° = 180°
vi) therefore the vertex angle y = 180° - 74° = 106°
Hence the given statement is true.
