Joe earned 2,100$. He spent 1/5 on rent and 1/4 on food. How much money did he have left?
The amount of money that Joe has left is $1155
How to calculate the amount of money left ?
Joe earned $2100
He spent 1/5 of the money on rent
1/5 × 2100
= 420
$420 was spent on rent
He spent 1/4 of the money on food
= 1/4 × 2100
= 525
$525 was spent on food
The amount of money left can be calculated as follows
Total amount spent = 525 + 420
= 945
Amount left= 2100 - 945
= 1155
Hence Joe has $1155 left

What is Ratio proportion?The divisional comparison of two quantities yields a ratio, and the equality of two ratios yields a proportion.
A ratio is commonly written as "x: y," though it can also be read as "x is to y" or "x/y."
In terms of comparison, a proportional equation says that two ratios are equal.
When x: y: z: w is used to represent a ratio, it is understood to mean that x is to y as z is to w.
In this case, w and Y are not equal to 0, therefore x/y Equals z/w.

what is 3 to the negative 8th power divided by 3 to the negative 4th power
Answer
Answer = 3⁻⁴ = (1/3⁴) = (1/81)
The answer is 3 raised to the power of negative 4 or 3 to the negative 4th power.
Explanation
The law of indices is usually applied when questions that involve same numbers with (different or the same) powers are considered.
When a number carrying a particular power is divided by the same number also carrying another power, the result is that same number raised to the power of the difference between the power of the numerator and the power of the denominator.
It'll be clearer in practice now.
[tex]\frac{3^{-8}}{3^{-4}}=3^{-8\text{ - (-4)}}=3^{-8+4}=3^{-4}[/tex]Hence, the answer is 3 raised to the power of negative 4 or 3 to the negative 4th power.

In parallelogram ABCD… Justify your answer with the applicable property.
Solution
For this case we have the following measures:
m <1= x+12
m < 2= 6x -18
We can set up both angles equal:
x +12 = 6x -18
Solving for x we have:
12+18 = 5x
5x = 30
x= 30/5= 6
Then the value of m< 2 is:

Sarah Meeham blends coffee for Tasti-Delight. She needs to prepare 190 pounds of blended coffee beans selling for
$4.55 per pound. She plans to do this by blending together a high-quality bean costing $5.50 per pound and a cheaper
bean at $3.50 per pound. To the nearest pound, find how much high-quality coffee bean and how much cheaper coffee
bean she should blend.
She should blend lbs of high quality beans.
(Round to the nearest pound as needed.)
By solving an equation we can say that Sarah needs to blend a total of 96 pounds of coffee beans.
What are equations?A mathematical equation is a formula that uses the equals sign to represent the equality of two expressions. A mathematical statement that has an "equal to" symbol between two expressions with equal values is called an equation. As in 3x + 5 Equals 15, for instance. Equations come in a variety of forms, including linear, quadratic, cubic, and others. The point-slope form, standard form, and slope-intercept form are the three main types of linear equations.So, the total pounds Sarah needs to blend:
Let the number of pounds by 'x'.Now form an equation as:
5.50x + 3.50x = 190 × 4.55Then, solve equation for 'x' as follows:
5.50x + 3.50x = 190 × 4.559x = 864.5x = 864.5/9x = 96 pounds
Therefore, by solving an equation we can say that Sarah needs to blend a total of 96 pounds of coffee beans.

Consider the polynomial function q ( x ) = − 2 x 8 + 5 x 6 − 3 x 5 + 50
The function has an end behaviour of x → ∞, q(x) → -∞ and x → -∞, q(x) → -∞
How to determine the end behaviour of the function?The equation of the polynomial function is given as
q(x) = -2x⁸ + 5x⁶ - 3x⁵ + 50
To determine the end behaviour of the function, we calculate
q(∞) and q(-∞)
So, we have
q(∞) = -2(∞)⁸ + 5(∞)⁶ - 3(∞)⁵ + 50
Evaluate the exponents
q(∞) = -2(∞) + 5(∞) - 3(∞) + 50
This gives
q(∞) = -∞ + ∞ - ∞ + 50
q(∞) = -∞
Also, we have
q(-∞) = -2(-∞)⁸ + 5(-∞)⁶ - 3(-∞)⁵ + 50
Evaluate the exponents
q(-∞) = -2(∞) + 5(∞) - 3(-∞) + 50
This gives
q(-∞) = -∞ + ∞ + ∞ + 50
q(-∞) = -∞
Hence, the end behaviour of the graph is x → ∞, q(x) → -∞ and x → -∞, q(x) → -∞

What is the greatest number of soda bottles Alex can
buy without going over budget?
If Alex has a $100 budget to buy food for his birthday, each pizza cost $10 and each soda bottle cost $3, and Alex bought 7 pizzas, then the greatest number of soda bottles Alex can buy without over budget 10 soda bottles
The total budget = $100
The cost of one pizza = $10
Number of pizza he bought = 7
The total cost of pizza = 7×10 = $70
The remaining money = 100-70
= $30
The cost of one soda bottle = $3
Number of soda bottle can he buy using the remaining money = 30/3
= 10 soda bottles

Equation:
An equation state that the value of two mathematical expressions is equal.
For example,
2x + 5 = 7
is an equation.
Given,
An electrician charges $25 per hour plus a one-time service fee of $50.
Here we need to find the equation for the given situation and we have also find the charge for the 3 hour of service.
Let us consider the equation of the line y = mx + c, where m represents the constant change and c represents the fixed constant.
While we apply these equation to the given situation we can get the value of
m = $25
And the value of
c = $50.
Therefore, the equation of the situation is
y = $25x + $50.
We have already now that the y represents the cost and the x represents the hour of service.
Now we have to find the service charge for 3 hours,
So we have to apply the value of x as 3 then we get,
=> y = $25 (3) + $50
=> y = $75 + $50
=> y = $125
Therefore, the cost for 3 hours is $125.

Step-by-step explanation:
Pre-SolvingWe are given the following inequality:
[tex]76 < 5-\frac{136}{s}[/tex]
And we want to know if s=2 is a solution, meaning if s is 2, will the inequality still be true?
SolvingWe can substitute 2 for s in the inequality to test it.
Replace s with 2.
[tex]76 < 5-\frac{136}{2}[/tex]
First, let's divide 136 by 2.
136/2 = 68
The inequality is now:
76 < 5 - 68
Subtract 68 from 5.
76 < -63
The inequality reads "76 is less than -63", which is a false statement (76 is positive, -63 is negative, and positive numbers are greater than negative numbers).
Ergo, s = 2 is not a solution to the inequality.
