Answer:
C. 0.187 lb of cashews and 0 313 lb of peanuts
Explanation:
Let's call x the number of pounds of cashews and y the number of pounds of peanuts.
If the owner wants a half-pound mixed, we get that the sum of the pounds of each product is 0.5 lb, so:
x + y = 0.5
On the other hand, cashews worth $5.75 a pound, peanuts worth $2.00 a pound, and the mixed nut bag worth $1.70, so we can write the following equation:
5.75x + 2y = 1.70
Where 5.75x is the worth of the cashews in the mixed and 2y is the worth of the peanuts in the mixed.
Therefore, we have the following system of equations:
x + y = 0.5
5.75x + 2y = 1.70
Solving the first equation for y:
x + y = 0.5
x + y - x = 0.5 - x
y = 0.5 - x
Subtitude y = 0.5 - x on the second equation:
5.75x + 2y = 1.70
5.75x + 2(0.5 - x) = 1.70
Apply the distributive property and add like terms:
5.75x + 2(0.5) - 2(x) = 1.70
5.75x + 1 - 2x = 1.70
3.75x + 1 = 1.70
Solve for x:
3.75x + 1 - 1 = 1.70 - 1
3.75x = 0.70
3.75x/3.75 = 0.70/3.75
x = 0.187
Finally, we can calculate the value of y as:
y = 0.5 - x
y = 0.5 - 0.187
y = 0.313
Therefore, the mixed bag will include 0.187 lb of cashews and 0.313 lb of peanuts.
Find the length of side AB. Round to the nearest hundredth inch.
The value of length of side AB is,
⇒ AB = 5 units
We have to given that;
The figure is shown a trapezoid.
Hence, By using Pythagoras theorem we get;
⇒ AB² = 4² + (5.25 - 2.25)²

You have $500,000 saved for retirement. Your account earns 7% interest. How much will you be able to pull out each month, if you want to be able to take withdrawals for 25 years?
$3,244.21 can be withdrawn each month for 25 years, assuming an interest rate of 7% and a starting principal of $500,000.
Formula to calculate the present value of the annuityPV = PMT × [1 - (1 + r)⁻ⁿ] / r
where:
PV is the present value of the annuity
PMT is the payment amount per period
r is the interest rate per period
n is the total number of periods
In this case, we want to withdraw a fixed amount each month for 25 years, which represents 12 ×25 = 300 periods.
The interest rate per period is 7% / 12 = 0.5833%.
Let's assume that you want to withdraw a fixed amount each month, and you want the withdrawals to last for 25 years. To calculate the amount you can withdraw each month,
PV = PMT × [1 - (1 + r)⁻ⁿ] / r
500,000 = PMT × [1 - (1 + 0.005833)⁻³⁰⁰] / 0.005833
Solving for PMT, we get:
PMT = PV × r / [1 - (1 + r)⁻ⁿ]
PMT = 500,000 × 0.005833 / [1 - (1 + 0.005833)⁻³⁰⁰]
PMT = $3,244.21
Therefore, you can withdraw $3,244.21 each month for 25 years, assuming an interest rate of 7% and a starting principal of $500,000.

x^2-4x=5
Let’s solve the equation x^2 - 4x = 5 by factoring:
First, we’ll move all the terms to one side of the equation:
x^2 - 4x - 5 = 0
Now, we’ll factor the left side of the equation. We’re looking for two numbers that multiply to -5 and add to -4. Those numbers are -5 and 1. So we can write:
(x - 5) (x + 1) = 0
Now we’ll use the zero-product property to solve for x. This property states that if the product of two numbers is zero, then at least one of the numbers must be zero. So we have:
x - 5 = 0 or x + 1 = 0
Solving each equation separately, we find that x = 5 or x = -1.
So, the solutions to the equation x^2 - 4x = 5 are x = 5 and x = -1.

And for any prism, the volume is the product between the 3 dimensions, then for any cube the volume is:
V = Length*Width*Depth.
In this case we know that the depth is 9dm, then also is the length and the width, and thus, the volume of this cube is:

One rectangle is "framed" within another. Find the area of the shaded region if the "frame" is 3 units wide.
The area of the shaded region, with a frame of 3 units wide, is 264 square units. The inner rectangle is 6x4 units, and the outer rectangle is 18x16 units.
To solve the given problem, we have to find the area of the shaded region if the frame is 3 units wide. If the frame is 3 units wide, then the dimensions of the inner rectangle (the shaded region) will be (12 - 6) × (10 - 6) which simplifies to 6 × 4.
Therefore, we can say that the inner rectangle has a length of 6 units and a width of 4 units.The dimensions of the outer rectangle are (12 + 3 + 3) × (10 + 3 + 3) which simplifies to 18 × 16. Therefore, we can say that the outer rectangle has a length of 18 units and a width of 16 units.
The area of the shaded region can be obtained by subtracting the area of the inner rectangle from the area of the outer rectangle. Therefore, the Area of the outer rectangle = length × width= 18 × 16 = 288 square units
Area of the inner rectangle = length × width= 6 × 4 = 24 square units
Area of the shaded region = Area of the outer rectangle - Area of the inner rectangle = 288 - 24= 264 square units
Therefore, the area of the shaded region is 264 square units.

To fill in the table of values for the equation y = 2x + 1, we can choose different values of x and substitute them into the equation to find the corresponding values of y. For example:
x y
0 1
1 3

To get the value of y, we substitute each value of x into the equation and simplify:
When x = 0:
y = 2(0) + 1 = 1
When x = 1:
y = 2(1) + 1 = 3

Janelle wants to put a fountain so that it is
5 units from statues A and B. What are possible
coordinates for the fountain? Explain.
Coordinate A: (-2,-1)
Coordinate B: (4,-1)
The possible coordinates for the fountain are (-11/4, -5/2) and (-11/4, 5/2),
What are possible coordinates for the fountain?To find the possible coordinates for the fountain that is 5 units away from both statues A and B, we can use the concept of distance formula.
The distance between two points (x1, y1) and (x2, y2) can be calculated using the distance formula:
d = √((x₂ - x₁)² + (y₂ - y₁))
In this case, the coordinates for statue A are (-2, -1) and the coordinates for statue B are (4, -1).
Let's assume the coordinates for the fountain are (x, y). We want the distance between the fountain and both statues to be 5 units.
Using the distance formula for statue A:
5 = √((-2 - x)² + (-1 - y)²)
Simplifying:
25 = (-2 - x)² + (-1 - y)² (equation 1)
Using the distance formula for statue B:
5 = √((4 - x)² + (-1 - y)²)
Simplifying:
25 = (4 - x)²+ (-1 - y)² (equation 2)
We have a system of equations (equation 1 and equation 2) that represents the conditions for the fountain's coordinates.
By solving this system of equations, we can find the possible coordinates for the fountain.
Note: The solution to this system of equations will provide two sets of coordinates that satisfy the given conditions.
To solve the equations, we can expand and simplify:
From equation 1:
25 = 4 + 4x + x² + 1 + 2y + y²
x² + y² + 4x + 2y - 20 = 0 (equation 3)
From equation 2:
25 = 16 - 8x + x² + 1 + 2y + y²
x² + y² - 8x + 2y - 9 = 0 (equation 4)
Now, we can solve equations 3 and 4 simultaneously.
Subtracting equation 4 from equation 3 we get:
(8x - 4x) + (-9 + 20) = 0
4x + 11 = 0
4x = -11
x = -11/4
Substituting the value of x back into equation 3:
(-11/4)² + y² + 4(-11/4) + 2y - 20 = 0
y² + 2y - 25/4 = 0
Solving this quadratic equation, we can find the possible values of y. Factoring the equation:
(y + 5/2)(y - 5/2) = 0
This gives us two solutions:
y + 5/2 = 0 -> y = -5/2
y - 5/2 = 0 -> y = 5/2
Therefore, the two possible coordinates for the fountain are (-11/4, -5/2) and (-11/4, 5/2).

A. when rolling a dice multiple times, the median is less likely to fall between numbers 1 and 6.
B. it's not possible to tell the likelihood of where the median is going to be when measuring probability since rolling dice is completely randomized, etc.
C. some other response
We can deduce that option A is likely to be true based on the given graph of rolling dice median data.
What is the median?The median is the value in the middle of a data set, which means that 50% of the data points have a value less than or equal to the median, and 50% of the data points have a value greater than or equal to the median.
The graph illustrates that the median value of the rolls is closer to the center of the possible outcomes (numbers 3, 4, and 5) than the extremes (numbers 1 and 6).
This implies that when rolling a dice several times, the median is less likely to fall between the numbers 1 and 6.

25-x = amount of 5% alcohol to use total amount of alcohol = .05 (25-x)
total alcohol in ingredients = total alcohol in end product
.30x + .05(25-x) = .15 (25)
