They are all nickels and dimes. The total value of the coins is $1.85. How many dimes does Leslie have? Which of the following systems is correct for
this situation?
The number of dimes is 13.
The system of equation for the situation is as follows;
x + y = 24
0.1x + 0.05y = 1.85
How to solve system of equation?The coins are 24.
Therefore, they are all dimes and nickel.
Total value of the coins is $1.85.
Hence, let
x = number of dimes
y = number of nickels
Therefore,
x + y = 24
0.1x + 0.05y = 1.85
0.1x + 0.1y = 2.4
0.1x + 0.05y = 1.85
0.05y = 0.55
y = 0.55 / 0.05
y = 11
x = 24 - 11
x = 13

What is the effect of multiplying the parent function f(x) = x ^ 2 by a positive constant?
Effect of multiplying the parent function f(x) = x ^ 2 by a positive constant, we get a function whose graph is stretched or compressed vertically in relation to the graph of the original function.
What happens when we multiply a parent function with a positive constant?A parent function in mathematics is the simplest function in a family of functions that preserves the concept of the entire family.When we multiply a function by a positive constant, we get a function with a graph that is stretched or compressed vertically in comparison to the original function's graph. If the constant is larger than one, we get a vertical stretch; otherwise, we get a vertical compression.Therefore, the effect of multiplying the parent function f(x) = x ^ 2 by a positive constant, we get a function whose graph is stretched or compressed vertically in relation to the graph of the original function.

a. Find the graph of their common region in the attachment
b. The area of the common region of the graphs is 8 units²
a. How to sketch the region common to the graphs?Since we have x ≥ 2, y ≥ 0, and x + y ≤ 6, we plot each graph separately and find their region of intersection.
The graph of x ≥ 2 is the region right of the line x = 2.The graph of y ≥ 0 is the region above the line y = 0 or x-axis.To plot the graph of x + y ≤ 6, we first plot the graph of x + y = 6 ⇒ y = -x + 6. Then the graph of x + y ≤ 6 is the graph of y ≤ - x + 6.So, the graph of x + y ≤ 6 is the region below the line y = - x + 6
From the graph, the regions intersect at (2, 0), (2, 4) and (6, 0)
Find the graph of their common region in the attachment
b. The area of the common regionFrom the graph, we see that the common region is a right angled triangle with
height = 4 units and base = 4 unitsSo, its area = 1/2 × height × base

a) calculate the length of QR
b) calculate the area of trapezium PQRS.
Thanks for helping.
Using the given information, length of QR = 16.6 cm
The area of the trapezium is 304.5 cm²
Calculating area of a trapeziumFrom the question we are to calculate the length of QR and the area of trapezium PQRS
In the given diagram,
Let the midpoint of PS be T
Then, we can write that
|OP|² = |OT|² + |PT|² (Pythagorean theorem)
|OP| = radius = 13 cm
|PT| = 1/2 × PS = 1/2 × 24 cm = 12 cm
∴ 13² = |OT|² + 12²
169 = |OT|² + 144
|OT|² = 169 -144
|OT|² = 25
|OT| = √25
|OT| = 5 cm
Also, let the midpoint of QR be U
Then, we can write that
|OQ|² = |OU|² + |QU|² (Pythagorean theorem)
|OQ| = radius = 13 cm
From the given information,
The distance of QR from O is twice the distance of PS from O
∴ |OU| = 2 × |OT|= 2 × 5 cm = 10cm
Thus,
13² = ||² + 12²
169 = 10² + |QU|²
|QU|² = 169 -100
|QU|² = 69
|QU| = √69
|QU| = 8.3 cm
Now,
Length of QR = 2 × |QU| = 2 × 8.3 cm
Length of QR = 16.6 cm
b)
Area of the trapezium = 1/2(|QR| + |PS|) × |TU|
Area of the trapezium = 1/2(16.6 + 24) × 15
NOTE: |TU| = |OT| + |OU|
Area of the trapezium = 1/2(40.6) × 15
Area of the trapezium = 20.3 × 15
Area of the trapezium = 304.5 cm²
Hence, the area of the trapezium is 304.5 cm²

The scale factor required will be 1:60 or 60:1 (actual:movie or movie:actual).
What is a scale factor?The scale factor is the simplest ratio between the actual and the model's size of the same object.
How to solve the question?In the question, we are informed that in a movie, a child who was 32 inches tall was ''blown up'' to be 160 feet tall.
We are asked to determine the scale factor needed for the props in the movie.
To find the scale factor, we first find the size of the child in the movie in inches.
Size = 160 feet = 160*12 inches = 1920 inches.
Now, the scale factor is calculated as the ratio of the actual size to the size in the movie, that is,
Scale factor = 32:1920 = 32/1920 = 1:60.
Therefore, the scale factor required will be 1:60 or 60:1 (actual:movie or movie:actual).

On the average, 1.8 customers per minute arrive at any one of the checkout counters of a grocery store. What probability distribution can be used to find the probability that there will be no customers arriving at a checkout counter in the next minute
The probability that there will be no customers arriving at a checkout counter in the next minute is 0.16530.
The number of customers arriving per minute at the checkout counter of a grocery store is following Poisson Distribution.
A Poisson Distribution over a variable X, having a mean λ, has a probability for a random variable x as [tex]P(X = x) = e^{-\lambda} \frac{\lambda^{x}}{x!}[/tex] .
In the question, we are asked to find the probability that no customer arrives at the checkout, hence we put x = 0, and the mean number of customers per minute (λ) = 1.8.
Substituting the values of x and λ in the equation, we get:

Step-by-step explanation:
A quadratic inequality is one that involves a quadratic polynomial.
IdentificationThe degree of a polynomial is the value of the largest exponent of the variable. When the degree of a polynomial is 2, we call it a quadratic.
For the following inequalities, the degree of the polynomial in x is shown:
y < 2x +7 . . . degree 1y < x^3 +x^2 . . . degree 3y < x^2 -5x . . . degree 2 (quadratic)ApplicationWe see that the degree of the polynomial in x is 2 in ...
y < x^2 -5x
so that is the quadratic inequality you're looking for.

Additional comment
When a term involves only one variable, its degree is the exponent of that variable: 5x^3 has degree 3. When a term involves more than one variable, the degree of the term is the sum of the exponents of the variables: 8x^4y3 has degree 4+3=7.

What is p ÷ r equal to?
tan x°
tan y°
sin y°
cos x°
Answer: tan x
Step-by-step explanation: An angle determines if a side is opposite the angle, or adjacent the angle. Since p/a is something to do with the tangent, as it is not using the hypotenuse (the longest side.) Tangent is Opposite/Adjacent, while Sine is Opposite/Hypotenuse and Cosine is Adjacent/Hypotenuse. The only thing that makes sense is tangent.
So, that leaves us with either tan y or tan x. Well, with x, the angle that x points to (which is the opposite side) is p, and the adjacent is a, so p/a must be Tangent(x) since it is Opposite/Adjacent sides.
Only if it was r/p would it be tan y, since r becomes the opposite and p becomes the adjacent.

The number, which on divided by 7 gives a quotient of 247 and a remainder of 3 is 1732. Computed using linear equations.
In the question, we are informed that a number when divided by 7, gives a quotient of 247 and a remainder of 3.
Assuming the number to be x.
We can say that x is our dividend, 7 is the divisor, 247 is the quotient, and 3 is the remainder.
The division algorithm equation is:
Dividend = Divisor*Quotient + Remainder,
Substituting values in this equation, we get a linear equation:
x = 7*247 + 3.
To solve for the unknown number x, we solve the equation as follows:
x = 7*247 + 3,
or, x = 1729 + 3,
or, x = 1732.
Thus, the number, which on divided by 7 gives a quotient of 247 and a remainder of 3 is 1732. Computed using linear equations.
