A sheet of plywood was made by gluing 7 sheets of wood together.
2 of the sheets were 0.0625 inch thick and the rest were 0.125 inch thick.
how thick was the plywood?

Answers

Answer 1
We can use the equation y=2(0.0625)+5(0.125), y being the thickness of the plywood.
I got 5(0.125) because two sheets of the 7 were already used, meaning there are 5 sheets of plywood left over.
y=0.125+0.625
y=0.75
Therefore, the plywood is 0.75 inches thick.

Answers

If your looking for the answer, this question is invalid. However, if the question is asking for the function equation, the answer is y=3x-2
Let "a" represent Alex' age.  Translating the given sentence into symbols, 

a = 3(a-2).  Thus, a = 3a - 6, or 6 = 2a, or a = 3.

Alex is 3 years old now.   (Answer)

I lost the little piece of paper that had my locker combination written on it! It takes me 10 seconds to try each of the combinations I can think of, and I have tried a total of 15 combinations so far! Looks like I am going to be late for class ...

Define a unit for the length of time spent trying combinations. Then enter a variable for the number of additional combinations tried and use this variable to write an expression for the length of time spent trying combinations.

Answers

Final answer:

The unit of time spent trying locker combinations is seconds, with the student already having spent 150 seconds. Introducing a variable x for additional combinations, the total time is expressed as 10x + 150 seconds.

Explanation:

Let's define the unit for the length of time spent trying combinations as seconds. Since the student spends 10 seconds on each try, and has tried 15 combinations, that's already 150 seconds spent. Now, let's introduce the variable x to represent the number of additional combinations the student will try. If each additional combination takes 10 seconds to try, then the total length of time spent trying combinations would be 10x seconds for the additional tries. Add this to the initial 150 seconds, and we get an expression for the total time spent as 10x + 150 seconds.

Can someone help me? (Algebra 1)

Answers

I believe real and rational.
Let's find out what the following terms mean, so we know what to choose from: 

 - An irrational number is a number that cannot be represented by a simple fraction. They can't be written as a ratio with two integers (like 55 = 55/1, 1.5 = 3/2, -.25 = -3/4). They are unable to repeat, and unable to end. Pi (3.1415926...) is a notable example of an irrational number. 1.7 as a fraction is 17/10. It can be written as a ratio with two integers, so it is not irrational. 

- A real number is a number that represents any quantity in a number line. It includes all numbers. Every number is a real number. So, 1.7 is a real number. 

- A whole number is a positive number (including 0) that does not include any fractions, decimals, radicals, etc. Numbers such as 5, 32 and 73 are considered whole numbers. 1.7 is not a whole number, since it is a decimal. 

- A rational number is a number that can be written as a fraction. Values such as whole numbers (ex: 3/1), negative numbers (ex: -7/1), decimals that can be successfully written as a ratio (ex: .5) are rational numbers. Unlike irrational numbers, these can end (3.4) and repeat (3.3333333333...). 1.7 is able to be written out as a fraction with two integers and it ends. It is a rational number. 

- A natural number is a positive whole number. So, naturals are greater than 0. numbers such as 1,2,3 and onward are natural numbers. 1.7 is a decimal;  it is not considered a natural number. 

- Integers are all the positive and negative whole numbers including zero. 123, -5000, and 34 are random examples of an integer. 1.7 is a decimal, so it is not an integer. 

God Bless. You are going to do great in not only math, but in all your classes!

TJ, Max, and Misha are all the same age. The sum of their ages is s years. How old was TJ eight years ago?
Thanks!

Answers

Let x = TJ's current age.
Therefore each of the three has the same age.
Because the sum of their ages is s, therefore
3x = s
x = s/3

TJ's age 8 years ago is s/3 - 8

Answer: s/3 - 8

Final answer:

TJ's age eight years ago is found by dividing the sum of their current ages, s, by 3 to find each person's age and then subtracting 8. Hence, TJ's age eight years ago is (s/3) - 8.

Explanation:

If TJ, Max, and Misha are all the same age and the sum of their ages is s years, we can establish that the age of each one of them is s/3. To determine how old TJ was eight years ago, we simply subtract eight from his current age.

So TJ's age eight years ago can be calculated as follows:

Find TJ's current age: TJ's age = s/3.

Subtract eight years to find his age at that time: Age eight years ago = TJ's age - 8

Therefore, TJ's age eight years ago = (s/3) - 8.

after a reflection over the line y=x (8,11) is the image of point c. what is the original location of point c

Answers

the original points/point c would be (-8,11) bc the y stays the same and the x changes from its original to (in this case) negative to positive
 
(positive to negative/negative to positive for either the x or y)

hope this helps
Final answer:

The original location of point C before a reflection over the line y=x, given that the image of point C is at (8,11), would be (11,8) as coordinates are swapped during such a reflection.

Explanation:

To determine the original location of point C before a reflection over the line y=x, you would apply a simple transformation rule. For any reflection over the line y=x, the coordinates of a point are swapped. Thus, if the image of point C is at (8,11), the original location of point C would have the x-coordinate as 11 and the y-coordinate as 8.

The step-by-step process to find the original location of point C before the reflection is as follows:

Take the x-coordinate of the image and make it the y-coordinate of the original point.Take the y-coordinate of the image and make it the x-coordinate of the original point.The resulting point is the original location of C before the reflection.

Therefore, the original location of point C is (11, 8).

Explanation:

Mary's improved performance in math after deciding to think of it as a fun challenge is an example of the power of mindset, specifically a growth mindset. A growth mindset is the belief that abilities and intelligence can be developed through dedication and hard work. By shifting her perspective and viewing math as a fun challenge rather than something she was inherently bad at, Mary adopted a growth mindset. This change in mindset likely led her to approach math with more enthusiasm, effort, and persistence, ultimately resulting in improved performance.

Is it possible for a number to be a rational number that is not an integer but is a whole number? Explain

Answers

Every whole number is a rational number: for example, 3=31. So it is rational. Every whole number n can be written as a fraction of integers: n=n1. We aren't required to write it that way; we just need to know that it is possible to express every whole number as a fraction of integers, and hence it is rational.

Mr Nemo has 5 desks while Mr Benn has 2 desks

We can say the following
number of desks Mr Benn has = (2/5)*(number of desks Mr Nemo has)
2 = (2/5)*(5)
2 = 2

Which basically is the math translation of "Mr Benn has 2/5 as many desks as Mr Nemo", so that's why choice C is one of the answers.

-----------------

Flip things around and we get

number of desks Mr Nemo has = (5/2)*(number of desks Mr Benn has)
5 = (5/2)*(2)
5 = 5

Note: 5/2 = 2 & 1/2

This is a translation from "there are 2 & 1/2 times as many desks in Mr Nemo's room as in Mr Benn's room" pointing to choice B as the other answer. 

Solve for x: one over eight(8x + 15) = 24

Answers

1/8(8x + 15) = 24

First step is to distribute.
(1/8)*8x + (1/8)*15 = 24
8/8x + 15/8 = 24

Now subtract 15/8 from both sides.
x = 24 - (15/8)
x = (192/8) - (15/8)
x = 177/8
x = 22.125

If a television screen with a length-to-height ratio of 16:9 has an area of 576in, what is it's perimeter?

Answers

Final answer:

The perimeter of the television screen is 100 inches.

Explanation:

To determine the perimeter of a television screen with a length-to-height ratio of 16:9 and an area of 576 square inches, we need to find the length and the height of the screen first.

Using the ratio, we let the length be 16x and the height be 9x.

The area of a rectangle is given by its length times its height, so we have:

(16x) × (9x) = 57

144x² = 576

x² = 576 / 144

x² = 4

x = 2

Now we can find the actual dimensions:

Length = 16 × 2 = 32 inches

Height = 9 × 2 = 18 inches

The perimeter (P) of a rectangle is given by

P = 2 × (Length + Height)

P = 2 × (32 + 18)

P = 2 × 50

P = 100 inches

The perimeter of the television screen is 100 inches.
