A woven rattan basket can hold up 6 lbs of items. A net bag of 4 oranges weighs 12 ounces. How many bags of oranges can the basket hold ?
[tex]\huge\boxed{8\ \text{bags of oranges}}[/tex]
Let's first find how many ounces the basket can hold.
1 pound is equal to 16 ounces. Multiply that to find how many ounces the basket can hold.
[tex]6\cdot16=96[/tex]
Now, divide the weight held by the basket by the weight of each bag of oranges.

Write a rational expression that satisfies the following condition: non permissible values x=y, +-2
The rational expression that satisfies x = y +-2 is 2xy/(x + y)(x² - 4).
How to illustrate the expression?It should be noted that non permissible value is the value of the variable which make the denominator of the rational expression equal to zero.
Based on the information, x + y gives x - y = 0.
x = 2 gives x - 2 = 0
x = -2 gives x + 2 = 0
Ths denominator according to the condition illustrated will be (x - y)(x - 2)(x + 2) = (x - y)(x² - 4)
Then, the rational expression can be written by taking the numerator and denominator. An example will be 2xy/(x + y)(x² - 4).

a lily pad is growing in a pond and it doubles in size every day. after 30 days it covers the entire pond. on what day does it cover half the pond?
The growth of the lily pad is in geometric progression, and it covers half the pond in 29 days.
In the question, we are given that the size of the lily pad doubles itself every day.
If we assume the size of the lily pad on the first day as a, then on the second day its size will be 2a, on the third day it will be 2(2a) = 4a, and on the fourth day, it will be 2(4a) = 8a, and so on.
This makes a geometric progression, with the first term as a, and the constant ratio as 2.
We are given that on the 30th day, the size of the lily pad, covers the entire pond.
The size on the 30th day can be shown as the 30th term of this geometric progression
Therefore, size of the pond = a(2)³⁰⁻¹ = a.2²⁹. {Using the formula, aₙ = arⁿ⁻¹, where aₙ is the n-th term, a is the first term, and r is the constant ratio}.
We are asked the day on which the pond is half covered.
The size of the pond in this case = (a.2²⁹)/2 = a.2²⁸.
The day can be calculated as follows:
a.2ⁿ⁻¹ = a.2²⁸,
or, 2ⁿ/2 = 2²⁸,
or, 2ⁿ = 2²⁹,
or, n = 29.
Thus, the lily pad covers half the pond on the 29th day.

See below for the demonstration of (e) graphing a line using x- and y-intercepts
The graphing method to demonstrateTo solve this question, we make demonstrate (e) graphing a line using x- and y-intercepts
The learning goalsAt the end of this exercise, you should be able to graph a line using x- and y-intercepts
A brief overviewA linear equation is represented as:
Ax + By = C
Where:
y-intercept = C/Bx-intercept = C/AThis means that we plot the points (0,C/B) and (C/A, 0) on a graph and then connect the points using a straight line.
Once this is done, the line has been graphed.
For instance, a line parallel to 3x + 8y = 16 will have a slope of -3/8
An original problem to solvePlot the graph of the following equation using the intercepts
2x + 4y = 10
We have:
2x + 4y = 10
Set x = 0 to determine the y-intercept
4y = 10
Divide by 4
y = 2.5
Set x = 0 to determine the x-intercept
2x = 10
Divide by 2
x = 5
So, we have:
(5, 0) and (0, 2.5)
Plot the above points and connect the points (see attachment for graph)
An original problem to solve by another studentPlot the graph of the following equation using the intercepts
3x + 6y = 18
We have:
3x + 6y = 18
Set x = 0 to determine the y-intercept
6y = 18
Divide by 6
y = 3
Set x = 0 to determine the x-intercept
3x = 18
Divide by 3
x = 6
So, we have:
(6, 0) and (0, 3)
Plot the above points and connect the points (see attachment for graph)

x is 45° (45 degrees.)
To find this out, we first need to understand the properties of a rectangle. A rectangle has opposite sides that are equal, but more importantly, all 4 interior angles of a rectangle are right angles, meaning they are all 90 degrees. These can also be denoted by 4 square boxes in each corner.
When a rectangle is cut diagonally, the rectangle becomes two right triangles, but when joined together, of course make a rectangle. When they are cut diagonally, the triangles are congruent triangles by the Hypotenuse-Leg (HL) Congruence property.
To find the missing x in this angle, we must know that x is apart of a right angle, and if 45 is next to it, x must also be 45 degrees (90-45 = 45)

Determine two pairs of polar coordinates for (3,-3) when 0
The two pairs of polar coordinates for the given point (3, -3) with 0° ≤ θ < 360° are (3√2, 135°) and (3√2, 315°).
What is a polar coordinate?A polar coordinate is a two-dimensional coordinate system, wherein each point on a plane is typically determined by a distance (r) from the pole (origin) and an angle (θ) from a reference direction (polar axis).
Next, we would determine the distance (r) and angle (θ) as follows:
r = √(3² + (-3)²)
r = √(9 + 9)
r = 3√2.
θ = tan⁻¹(-3/3)
θ = tan⁻¹(-1)
θ = 3π and 7π/4 (second and fourth quadrants).
Converting to degrees, we have:
θ = 135° and 315°.

Answer:
x = 10
Step-by-step explanation:
Interior angles of a triangle sum to 180°
Therefore, to find the value of x, sum the given angles, equal them to 180, then solve for x:
⇒ 6x + 8x + 4x = 180
⇒ (6 + 8 + 4)x = 180
⇒ 18x = 180
⇒ 18x ÷ 18 = 180 ÷ 18

The probability that a randomly selected event of washing dishes will take a person between 8 and 13 minutes is 66.66%.
It is given that the time it takes a person to wash the dishes is uniformly distributed between 6 minutes and 14 minutes.
That means that the number of possible minutes it will take will be 6, 7, 8 ,9, 10, 11, 12, 13, 14 That's a total of 9 separate minutes or intervals.
If it takes between 8 and 13 minutes, that is only 8 ,9, 10, 11, 12, 13 that's only 6 separate minutes or intervals.
