The expression '2+8' simplifies to 10. Factoring using the Greatest Common Factor (GCF) is commonly used with expressions that contain variables.

The expression you're looking to factor, 2+8, does not really involve any complex mathematical concepts, and there's no variable to enable factoring in its usual way. However, we can simplify it by adding the numbers. So, 2+8 equals to 10. Factoring using the greatest common factor(GCF) is most often used when you're handling expressions that involve variables, for instance, 2x + 8x. In this case, the GCF would be 2x, and the expression would factor to 2x(1 + 4).

To obtain a 35% antifreeze solution, you need to add approximately 1.857 gallons of water to 1 gallon of pure antifreeze.

To obtain a 35% antifreeze solution, you need to add a certain amount of water to 1 gallon of pure antifreeze. Let's assume that x gallons of water should be added. In a 35% antifreeze solution, the amount of antifreeze is 35% of the total solution. So, we can set up the following equation:

1 gallon of antifreeze = (35/100) * (1 + x) gallons of solution

Simplifying this equation, we get:

1 = 0.35 * (1 + x)

Now, let's solve for x:

Divide both sides of the equation by 0.35:

1/0.35 = 1 + x

2.857 = 1 + x

Subtract 1 from both sides of the equation:

2.857 - 1 = x

x = 1.857 gallons of water

Therefore, you need to add approximately 1.857 gallons of water to 1 gallon of pure antifreeze to obtain a 35% antifreeze solution.

Final answer:

To obtain a 35% antifreeze solution from 1 gallon of pure antifreeze, approximately 1.857 gallons of water needs to be added. This calculation is based on a simple concentration equation, resulting in the given ratio.

Explanation:

To calculate the amount of water to be added to 1 gallon of pure antifreeze to obtain a solution that is 35% antifreeze, we need to perform a simple concentration calculation.

We are starting with pure antifreeze, so it's 100% antifreeze. We want to end with a solution that is 35% antifreeze. Let's denote the amount of water added as x gallons. Because we are diluting the antifreeze, the total volume of the solution after adding water will be 1 gallon (the initial volume of the antifreeze) plus x gallons (the volume of water added).

The concentration of antifreeze after adding water is the volume of antifreeze divided by the total volume of the solution:

Concentration of antifreeze = Volume of antifreeze / Total volume of solution

Thus, 0.35 = 1 / (1 + x)

Multiplying both sides by (1 + x) and then by 0.35 we get:

1 = 0.35 * (1 + x)

Dividing by 0.35 and then subtracting 1:

x = 1 / 0.35 - 1

After calculating:

x ≈ 1.857 gallons

To obtain a 35% antifreeze solution, approximately 1.857 gallons of water should be added.

The distance from the tip of the shadow to the top of the tree is 42.426 meters.

Pythagoras theorem is a relation between sides of a right-angle triangle.

It states that for a right-angle triangle the square root of Hypotenuse is equal to the sum of the individual base and perpendicular square.

So,

Hyp² = Base² + Perp²

Given the situation is making a right angle triangle with base and perpendicular as 30 meters.

By Pythagoras theorem,

Hyp² = Base² + Perp²

Hyp² = 30² + 30²

Hyp² = 1800

Hyp = 42.426 meter.

Hence "The distance from the tip of the shadow to the top of the tree is 42.426 meters".

The correct answer is 43-a. In other words, the result of simplifying algebraic expressions 43 + a - 2a is 43 - a.

To simplify the expression 43 + a - 2a, you can combine like terms.

The expression consists of three terms: 43, a, and -2a.

Starting with the numbers, 43 is a constant term and does not contain any variables. Since there are no other terms with numbers, 43 remains unchanged.

Next, let's simplify the terms with variables. We have a and -2a. To combine these terms, we can group them together as a single term.

The term with a is positive a, and the term with -2a is negative 2a. When we combine them, we subtract 2a from a. This gives us a - 2a, or -a.

Therefore, the simplified expression is 43 - a.

Therefore, the correct answer is 43-a. In other words, the result of simplifying algebraic expressions 43 + a - 2a is 43 - a.

To find the original cost price of a shirt on which an 8% discount was given, resulting in a sale price of Rs.161, the formula CP = Sale Price / (1 - (Discount Percent / 100)) is used, calculating the cost price as Rs.175.

If the sale price of a shirt after giving an 8% discount is Rs.161, to find the written price, or the cost price before the discount, we can use the formula for discount calculation. Let CP represent the cost price. The formula for calculating the sale price after discount is:

Sale Price = CP - (Discount Percent * CP) / 100

Here, the sale price is given as Rs.161, and the discount percent is 8%. Therefore, we can rearrange the formula to solve for CP:

CP = Sale Price / (1 - (Discount Percent / 100))

Plugging in the values gives us:

CP = 161 / (1 - (8 / 100)) = 161 / 0.92 = Rs.175

Therefore, the written price or the cost price of the shirt before the discount was applied is Rs.175.

The explicit rule for the remaining train sets after 'n' months is represented by the formula T(n) = 35 - 3n, where T(n) is the total number of train sets, and 'n' is the number of months.

The explicit rule for the number of train sets a store has after ‘n’ months, given that the store starts with 35 train sets and sells 3 each month, can be represented by a linear equation. The initial amount of train sets is the starting point, and the number of sets sold each month is the rate of change.

The explicit rule for the number of train sets the store has after 'n' months can be represented by the linear function:

\[ T(n) = 35 - 3n \]

Here, \( T(n) \) represents the number of train sets after 'n' months, 35 is the initial number of train sets, and 3n represents the number of train sets sold each month. The negative coefficient (-3) indicates the decrease in the number of train sets each month. By plugging in different values for 'n', you can determine the number of train sets the store will have at any given month.

This is reflected in the equation:

T(n) = 35 - 3n

where T(n) represents the total number of train sets after n months, and n is the number of months that have passed.
