Answer:
Rs5000
Step-by-step explanation:
Let the equal amount of money they both brought = x
Mehrine spent Rs 500 on a pair of shoes, therefore, the money Mehrine has left
= x-500
Zaara bought a dress for Rs 2000, therefore, the money Zaara has left
= x-2000
Zaara has ⅔ of what Mehrine had left.
Therefore:
[tex]x-2000=\dfrac{2}{3} (x-500)[/tex]
Cross multiply
3(x-2000)=2(x-500)
3x-6000=2x-1000
3x-2x=6000-1000
x=5000
Therefore, Mehrine brought Rs5000 for shopping.

Answer:
The correct option is:
The function is decreasing for all real values of x where x < 1.5.
Step-by-step explanation:
We are given a function f(x) which is a product of two linear polynomial as:
Now, we know that on multiplying the two linear polynomial we will obtain a quadratic polynomial.
So, the function f(x) will be represented as:
So, we will plot the graph of the function and check which statements about the function hold true.
1)
The function is increasing for all real values of x where x < 0.
This statement is false.
Since we get from the graph that function f(x) is decreasing for x<0.
2)
The function is increasing for all real values of x where x < –1 and where x > 4.
This option is incorrect as the function is decreasing for x<-1
whereas it is increasing for x>4.
3)
The function is decreasing for all real values of x where –1 < x < 4.
This option is incorrect.
Since, the function is both decreasing as well as increasing in the interval (-1,4).
4)
The function is decreasing for all real values of x where x < 1.5.
This option is correct.
Since it could be observed from the graph that the function is decreasing for x<1.5.

Determine the missing segment
Let the missing segment be represented with x
Given that, there exist parallel lines between the two triangles;
The relationship between the sides of the triangles is as follows;
[tex]\frac{15}{x} = \frac{15+5}{8+x}[/tex]
[tex]\frac{15}{x} = \frac{20}{8+x}[/tex]
Cross Multiply
[tex]15 * (8 + x) = 20 * x[/tex]
Open bracket
[tex]15*8 + 15 * x = 20 * x[/tex]
[tex]120 + 15x = 20x[/tex]
Subtract 15x from both sides
[tex]120 + 15x -15x= 20x-15x[/tex]
[tex]120 = 20x-15x[/tex]
[tex]120 = 5x[/tex]
Divide both sides by 5
[tex]\frac{120}{5} = \frac{5x}{5}[/tex]
[tex]\frac{120}{5} = x[/tex]
[tex]24 = x[/tex]
[tex]x = 24[/tex]
Hence, the length of the missing segment is 24

Solve the inequality.
9 +6 > 5
9 > 11
g > 1
g> -1
Answer: g> -1
Step-by-step explanation:
The given inequality is [tex]g+6>5\ .[/tex]
To solve the above inequality for g, we just need to remove 6 from the left side by subtracting it, for that we have to subtract 6 from both the sides, we get
[tex]g+6-6>5-6\\\\\Rightarrow\ g>-1[/tex]
i.e. The value of g is strictly greater than -1.
Hence, the correct answer is g> -1.
Subtraction Property of Inequality says that if the same number is subtracted from both sides on the inequality then the sense (equality symbol) of the inequality remains unchanged.

The law used to simplify the expression is quotient of powers.
What is an expression?Expressions in math are mathematical statements that have a minimum of two terms containing numbers or variables, or both, connected by an operator in between.
Given is an expression, 3¹⁰ / 3⁴, we need to determine the law used to simply the expression,
3¹⁰ / 3⁴
For this case we have an expression formed by a division of powers of the same base in which we must apply a law to simplify said expression.
By the definition we have the property of the power quotient of the same base set:
xᵃ / xᵇ = x⁽ᵃ⁻ᵇ⁾
So, using the same,
3¹⁰ / 3⁴ = 3⁽¹⁰⁻⁴⁾ = 3⁶
Thus, to simplify the expression we must use the property of the power quotient of the same base.
Hence, the law used to simplify the expression is quotient of powers.

What is the inverse of the function f(x)= 1/4x-12
Answer:
The inverse is 4x+48
Step-by-step explanation:
y = 1/4x - 12
Exchange x and y
Solve for y
x = 1/4y -12
Add 12 to each side
x+12 = 1/4 y -12+12
x+12 = 1/4y
Multiply each side by 4
4(x+12) = 4*1/4y
4x+48 = y
The inverse is 4x+48
Answer:
4x + 48
Step-by-step explanation:
f(x) = 1/4x-12
y = 1/4x - 12
Switch variables.
x = 1/4y - 12
Solve for y.
x = 1/4y - 12
Add 12 on both sides.
x + 12 = 1/4y - 12 + 12
x + 12 = 1/4y
Multiply both sides by 4/1.
4/1(x + 12) = 1/4y × 4/1
4x + 48 = y

Solve the geometric probability scenario that you created for question #1. Include all appropriate geometric formulas, and when applicable, leave your answer in terms of and include all necessary calculations.
Answer:
π/100
Step-by-step explanation:
"A baseball is hit inside a baseball diamond with a length and width of 90 feet each. What is the probability that the ball will bounce on the pitcher's mound, if the diameter of the mound is 18 feet? Assume that the ball is equally likely to bounce anywhere in the infield. When applicable, leave your answer in terms of π and include all necessary calculations."
The probability that the ball lands in the pitcher's mound is:
P = area of mound / area of field
P = πr² / s²
P = π (9)² / (90)²
P = π/100
If the diameter of the mound is 18 feet then the probability that the ball will bounce on the pitcher's mound will be π/100.
How to find the geometric probability?When probability is in terms of area or volume or length etc geometric amounts (when infinite points are there), we can use this definition:
E = favorable event
S = total sample space
Then:
[tex]P(E) = \dfrac{A(E)}{A(S)}[/tex]
where A(E) is the area/volume/length for event E, and similar for A(S).
The probability that the ball lands in the pitcher's mound is,
P = area of mound / area of field
P = πr² / s²
P = π (9)² / (90)²
P = π/100
Hence, the probability that the ball will bounce on the pitcher's mound will be π/100.

Answer:
[tex]\boxed{<a = 62 degrees}[/tex]
[tex]\boxed{<b = 118 degrees}[/tex]
Step-by-step explanation:
A) If AB is a diameter, Then ACB is a 90 degrees angle because In a semi-circle (AB is a diameter which divides the circle into 2 equal parts), the angle opposite to the diameter is of 90 degrees.
So, <ACB = 90 degrees
Then <a = 180-90-28
=> <a = 62 degrees
B) The opposite interior angles of a quadrilateral inscribed in a circle add up to 180 degrees.
So,
=> <a + <b = 180
=> <b = 180-62
=> <b = 118 degrees

Answer:
17
Step-by-step explanation:
Using Triangle Midsegment theorem, it states that if :
Q is the midpoint of MN and R is the midpoint of NP
Then, QR is parallel to MP and QR = 1/2 of MP
Mathematically
QR = 1/2MP
From the above question, we are given the following values:
QR = 3x - 4
MP = 55 - 3x
Since
QR = 1/2MP
3x - 4 = 1/2(55 - 3x)
3x - 4 = 55/2 - 3x/2
Collect like terms
3x + 3x/ 2 = 55/2 + 4
9x/ 2 = 31.5
Cross Multiply
9x = 31.5 × 2
9x = 63
x = 63/9
x = 7
Since QR = 3x - 4
x = 7
QR = 3×7 - 4
= 21 - 4
= 17
Hence, QR = 17
What is the hypotenuse of a right triangle ABC with sides a=12 and b=5?
A)169
B)13
C)17
D)7
Answer:
B: 13
Step-by-step explanation:
To find the length of the hypotenuse of a right triangle, you can use the Pythagorean theorem if you know the length of the other two sides. Basically, you square the length of the 2 sides, a and b, and then add them together. Take the square root of the result to get the hypotenuse.
1. Square the length of a and b.
12 * 12 = 144
5 * 5 = 25
2. Add them together.
144 + 25 = 169
3. Take the square root.
The square root of 169 is 13.
In other words, the hypotenuse of this triangle is equal to √a^2 + b^2 = √12^2 + 5^2 = 13
