The local grocery store mixed 13 oz of planters mixed nuts with 19.5 oz of emerald mixed nuts to get 32.5 oz bags of mixed nuts that contain 56% peanuts.
What is an equation?An equation is an expression that shows the relationship between two or more numbers and variables.
Let x represent the amount of planters mixed nuts and y represent the amount of emerald mixed nuts, hence:
x + y = 32.5 (1)
Also:
0.5x + 0.6y = 0.56(32.5) (2)
From both equations:
x = 13, y = 19.5

Using translation concepts, the formula for function g(x) is given by the following option:
D. g(x) = 2^(x - 2)
What is a translation?A translation is represented by a change in the function graph, according to operations such as multiplication or sum/subtraction either in it’s definition or in it’s domain. Examples are shift left/right or bottom/up, vertical or horizontal stretching or compression, and reflections over the x-axis or the y-axis.
From the graph of the functions, we have that:
f(x) = 2 when x = 1.g(x) = 2 when x = 3.f(x) = 4 when x = 2.g(x) = 4 when x = 4.This means that g(x) is a shift right of 2 units of f(x), that is:
g(x) = f(x - 2).
Hence:
g(x) = 2^(x - 2)
The formula for function g(x) is given by the following option:

What is a rectangle, exactly?
The internal angles of a rectangle, which has four sides, are all exactly 90 degrees. At each corner or vertex, the two sides come together at a straight angle. The rectangle differs from a square because its two opposite sides are of equal length.p = 2w + 2l

Factories: a factory produces 6 motorcycles in 9 hours. Write a proportion and solve it to find how many hours it takes to produce 16 motorcycles.
Answer: x=24
6:9, 16 is to x = 16:x
6/9=16/x
multiply both sides by x
6x/9=16
multiply both sides by 9
6x=144
divide by 6
x=24
Answer:
6 motorcycles/ 9 hours = 16 motorcycles/x hours
to complete a proportion you need to multiply the cross products
9(16)=6x
144=6x
144/6=6/6 x
24=x
it will take 24 hours to produce 16 motorcycles
What to do if B is negative in a transformation? Does it become a positive fraction or stay a negative fraction when reflected over the y axis?
Step-by-step explanation:
what is B in your question ? you did not tell us.
since you mention "fraction", I assume B is the slope of a line ?
if that is the case, please remember, the slope is (y coordinate change / x coordinate change) when going from one point of the line to another.
the way you phrased it I assume the slope was originally negative.
that means either the y difference or the x difference was negative (but not both, otherwise it would have been a positive fraction again).
let's look at what happens, when things get reflected across the y axis :
things go from the left side (negative x values) to the right side (positive x values) of the y axis or vice versa.
and things stay on the same side of the x axis (either above the x-axis with positive y values, or below the x-axis with negative y values).
so, that reflection causes the x values to flip their sign, but the y values stay the same.
so, if y was originally negative, then x must have been positive. after the reflection x is now negative too, that makes the y/x fraction -/- = +/+ positive.
if y was originally positive, then x must have been negative. after the reflection x is now positive too, that makes the y/x fraction +/+ positive.
therefore, in every case, the reflected slope fraction must be positive.

At a carnival, the object of a game is to throw a dart at the board and hit region III.
d. What is the probability that it hits region IV?
The probability that it hits region IV is 30%.
Probability:
Probability means the possibility of the particular event.
And it can be calculated as,
P(A) = n(A)/n(S)
Where,
P(A) is the probability of an event “A”
n(A) is the number of favorable outcomes
n(S) is the total number of events in the sample space.
Given,
At a carnival, the object of a game is to throw a dart at the board and hit region III.
Here we need to find the probability that it hits region IV.
Consider the board was look like the following figure.
Then based on the given figure,
First, we have to find the total area of the board and the area of the required region.
And then we have to compare it to calculate the Probability.
So, the total area of the board is,
=> total area of the board = (10 + 30)(10 + 15)
=> total area of the board = 1000 in²
Now, the The area of the region IV is
=> Area = (10)(30)
=> Area = 300 in²
Therefore, the probability that it hits region IV is
=> P = 300/1000
=> P = 30/100
=> P = 30%
Therefore, the probability that it hits region IV is 30%.

Find the distance between pair of parallel lines with the given equations.
y=-6 y=1
The distance between pair of parallel lines with the given equation
y=-6 y=1 is 7 units
Definition of parallel linesParallel lines are any two or more lines that lie in the same plane but never cross one another. Both have the same slope and are equally distant from one another. No matter how far we extend a parallel line, it will always remain straight.
The fundamental characteristics listed below make it simple to recognize parallel lines.
Straight lines which are always the same distance apart from one another are known as parallel lines.No matter how far apart they are from one another, the parallel lines can never intersect.The two lines have the coefficient of x, zero. So, the slopes are 0.
Therefore, the lines are horizontal lines passing through y = −6 and y = 1.

a. What is the solution of this system of equations? 3x + 7y = 15 , 5x +2y = -4.
The solution of the system of equations involving 3x + 7y = 15 and 5x + 2y = -4 is (-2 , 3).
A system of linear equations is a set of two or more equations which includes common variables. To solve system of equations, we must find the value of the unknown variables used in the equations that must satisfy both equations.
There are three methods that can be used to solve system of linear equations.
1. Elimination
2. Substitution
3. Graphing
Using substitution method, given two linear equations in x and y,
3x + 7y = 15 (equation 1)
5x + 2y = -4 (equation 2)
Using the first equation, find the value of one variable, lets say x, in terms of the other.
3x + 7y = 15 (equation 1)
3x = 15 - 7y
x = 5 - (7/3)y
Substitute the equation of x to the second equation.
5x + 2y = -4 (equation 2)
5[5 - (7/3)y] + 2y = -4
25 - (35/3)y + 2y = -4
Combining all terms containing the variable y on one side and the constants on the other side of the equality, and solving for y.
25 - (35/3)y + 2y = -4
- (35/3)y + 2y = -4 - 25
-(29/3)y = -29
y = 3
Substitute the value of y in the equation of x.
x = 5 - (7/3)(3)
x = 5 - 7
x = -2
Hence, the solution of the given system of equations is (-2 , 3).

The area of the two bases and the area of the curved surface are added to determine the cylinder's total surface area. Consequently, the following is the formula for the cylinder's total surface area:
Area of the two bases plus the area of the curved surface equals the cylinder's total surface area. Due to the cylinder's round bottoms, their combined area will be equal to r2 + r2. We already know that a cylinder's curved surface area is 2rh.

Your dog takes off from your house after seeing a cat run across the street. If your dog started from rest and achieved 5.5 m/s in 3 seconds, what is the acceleration of your dog?
The acceleration of the dog is approximately 1.83 meter per second² .
Acceleration is defined as the rate of change of velocity . The change in velocity per unit time is acceleration.
The formula to calculate acceleration is given by acceleration = velocity ÷ time.Negative acceleration is called deceleration.Acceleration can be uniform or non-uniform.In the given problem the dog started from rest and achieved the final velocity of 5.5 m/s.
Let us use Newton's laws to write the equation:
v = u + at , where v is the final velocity , u is the initial velocity , a is acceleration and t is time.
The dog starts from rest so the initial velocity is 0.
given v=5.5 /s and t = 3 seconds
putting the values we get:
v = u + a t
or , 5.5 = 0 + 3a
or, a = 5.5/3 meters per seconds²
or, a = 1.8333... m/s²
or, a ≈ 1.83 m/s²
