Answer:

Step-by-step explanation:

The product of a number and its reciprocal is always 1, because multiplying a number by 1 divided by itself simplifies to 1.

The product of a number and its reciprocal is always 1. This is because a reciprocal is defined as 1 divided by the number. For any non-zero number x, the reciprocal is [tex]\frac{1}{x}[/tex]. Therefore, when you multiply a number by its reciprocal, x × [tex]\frac{1}{x}[/tex], you are essentially multiplying the number by 1 divided by itself, which simplifies to 1.

For example, the reciprocal of 2 is [tex]\frac{1}{2}[/tex], and when you multiply 2 by [tex]\frac{1}{2}[/tex], the product is 2 × [tex]\frac{1}{2}[/tex] = 1. This concept is crucial in mathematics, as it underlies the operations of division and multiplication, where division by a number is the same as multiplying by its reciprocal.

Hello!  I know somebody might have already answered this question, but I figured I could add more to it. In order to help you know whenever a question shows up like this again, I'll make an ordered situation for you.

Let's go ahead and make the situation!

The Situation:  Let's call the person trying to figure this problem out by Alison.  Alison turns on the water and allows it to run in the tub for about 9 minutes. She then turns the water off while she runs to answer the front door. She soon comes back and allows water to run into the tub for a couple more minutes before she takes a short bath. After the bath, Alison allows the water to completely drain from the tub.  That's how the problem would've went, but your question.

When you're asking the question you're also trying to figure out how it would've gone.  So, since you tried following the paragraph I made for the picture/problem I can show how'd it help you comprehend it better.  After Alison turns on the water, turns it back off then comes back to run the water AGAIN.. She finally drains it from the tub, which is what the picture exactly shows.  BUT when did she turn it off?!!!

Look at the problem, at the point where the Water level(in) starts decreasing.  We know that we end with the Water level(in) at 0, but how'd it get there?  The point at 12 in time is when it starts decreasing! But, from there it continues until it's at 15(min)

THE FINAL ANSWER: At 12(min) it decreases until it hits 15(min) which is when the tub is empty.  So, if you do common math 15(min) - 12(min) is 3(min)  So, it took 3(min) to empty the tub when it was the most full.

Final answer:

The long division for 6,250 ÷ 5 results in 1,250. By dividing each place value by 5 methodically, you arrive at the total step by step.

Explanation:

Performing Long Division

To perform the long division for 6,250 ÷ 5, you divide 6,250 by 5. Here’s the step-by-step process:

First, you look at the thousands place. 6,000 divided by 5 gives you 1,200. So you write 1,200 above the division bar.

Next, since you accounted for 5,000 of the 6,250, you have 1,250 left. Then divide 1,000 by 5 to get 200, and write this under the 1,200.

Now you have accounted for 6,000 and only 250 remain. You divide 250 by 5 to get 50 and write this under the 200.

Add the totals above the division bar: 1,200 + 200 + 50 to get 1,250.

The answer to 6,250 ÷ 5 is 1,250. This is how you use long division to solve this problem.

To calculate the Black Friday price of the TV, first determine 30% of the original price, which is $75. Subtract this discount from the original price of $250, which yields a Black Friday price of $175.

The subject of this question falls under Mathematics, specifically dealing with percentages. The price of the TV on Black Friday would be calculated by first determining the discount amount, which is 30% of the original price of $250.

Calculate 30% of $250 by multiplying 250 by 0.30 (30/100). That gives you $75.

The Black Friday price of the TV is the original price minus the discount amount. Therefore, $250 - $75 equals $175. So, the price of the TV on Black Friday would be $175.

Final answer:

The original price of the jeans before the 15% off sale was $13.53, calculated by dividing the sale price of $11.50 by 0.85.

Explanation:

To determine the original price of the jeans before the sale, we must first understand that the final price of $11.50 represents 85% of the original price, since the jeans were on a 15% off sale. To find the original price, we divide the sale price by 0.85 (which is 85% expressed as a decimal).

The calculation is as follows: Original Price = Sale Price / 0.85 = $11.50 / 0.85

When we do this calculation, we get:

Original Price = $13.53 (rounded to the nearest cent)

Therefore, the jeans were originally priced at $13.53 before the 15% discount was applied.

Final answer:

The original price of the jeans before the 15% sale was found by dividing the sale price, $11.50, by 0.85 which equals $13.53.

Explanation:

To determine the original price of the jeans before the 15% off sale, you consider that the sale price represents 85% of the original price (100% - 15% = 85%). Since the jeans were sold for $11.50 after the discount, you can set up the equation 0.85 × (original price) = $11.50. To solve for the original price, you would divide $11.50 by 0.85.

The calculation would look like this:

Therefore, the original price of the jeans was $13.53 before the sale.

There are 11 colored pencils and 99 markers.

Equations are mathematical statements with two algebraic expressions flanking the equals (=) sign on either side.

It demonstrates the equality of the relationship between the expressions printed on the left and right sides. LHS = RHS is a common mathematical formula.

Coefficients, variables, operators, constants, terms, expressions, and the equal to sign are some of the components of an equation. The "=" sign and terms on both sides must always be present when writing an equation.

Given:

Mrs. O'Neill has 9 times as many markers as colored pencils.

Total number of markers and colored pencils = 110.

let the number of colored pencils be x.

Then, number of markers = 9x

Thus x+ 9x = 110

10x =110

x= 11

So, there are 11 colored pencils and 99 markers.

Final answer:

Mrs. O'Neill has 11 colored pencils.

Explanation:

To solve the problem of how many colored pencils Mrs. O'Neill has, let's denote the number of colored pencils as x. According to the information given, Mrs. O'Neill has 9 times as many markers as she has colored pencils, so the number of markers is 9x.

The total number of markers and colored pencils is 110, represented by the equation x + 9x = 110.

Solving this equation will help us find the value of x:

Mrs. O'Neill has 11 colored pencils.

0.625 inches on the map represents 1 mile.

To find how much distance on the map represents 1 mile when [tex]\frac{1}{2}\ inch[/tex] represents [tex]\frac{4}{5}\ mile[/tex], set up a proportion.

If [tex]\frac{1}{2}\ inch = \frac{4}{5} \ mile[/tex], then we can set up the equation:

x inches = 1 mile

First, we recognize that:

Next, using the proportion, we can set up and solve for x:

[tex]\frac{0.5\ inch}{0.8\ mile} =\frac{x\ inch}{1\ mile}[/tex]

Cross-multiplying gives:

0.5 * 1 = 0.8 * x

0.5 = 0.8x

Solving for x:

[tex]x = \frac{0.5}{0.8}[/tex]

x = 0.625 inches

Therefore, 0.625 inches on the map represents 1 mile.

Mrs. Gee should arrange the 24 carpet squares in a rectangle of 6 by 4 squares to achieve the smallest perimeter of 20 units.

Arranging Carpet Squares with the Smallest Perimeter

To minimize the perimeter when arranging 24 carpet squares, Mrs. Gee should create a shape that is as close to a square as possible. Since 24 is not a perfect square, we look for dimensions that are factors of 24 that are closest to each other, which are 6 and 4. This would create a rectangle that is 6 squares long and 4 squares wide. Arranging the carpet squares in this manner results in a perimeter of:

(6 + 4) x 2 = 20 units

This is the smallest possible perimeter for 24 squares with whole number side lengths.

The constant term in the function y=10x+25, representing the number of trading cards Sean has, is 25. This term is best interpreted as the number of cards Sean had when he started his collection, which corresponds to Option A.

The function y=10x+25 represents the number of trading cards Sean has over time, where y is the number of cards and x is the time in months since he began collecting. The constant term in this linear equation (the number 25) is the y-intercept, which is the value of y when x is zero. This term represents the number of cards that he had when he started his collection. It shows us that before any months have passed (when x=0), Sean already had 25 cards. Therefore, the best interpretation of the constant term in this function is Option A: the number of cards that he had when he started his collection.
