DEEPER A science teacher showed an image of a carpenter bee on a wall. The image is 10 times as large as the actual bee. Then he showed another image of the bee that is 10 times as large as the first image. What is the length of the bee in the second image?
Answer:
The length of the bee in the second image is 100 times the original.
Step-by-step explanation:
A science teacher showed an image of a carpenter bee on a wall. The image is 10 times as large as the actual bee.
Let the size of the actual bee be = x
So, the first image is = 10x
Then he showed another image of the bee that is 10 times as large as the first image.
Now as the length of the carpenter bee is not given, you can multiply the given length by 100 to get the answer.
The second image will be = [tex]10\times10x=100x[/tex]
So, the length of the bee in the second image is 100 times the original.
5. For each conjecture, test the conjecture with several more examples or find a counter example to disprove it.
A. For every integer n, the value of n^2 is positive.
The conjecture that for every integer n, the value of n^2 is positive, is true
How to prove the conjecture?The conjecture is given as:
For every integer n, the value of n^2 is positive.
Let n be a positive integer.
Such that:
n = k
This means that:
n^2= k^2 --- positive
Let n be a negative integer.
Such that:
n = -k
This means that:
n^2= (-k)^2
Evaluate
n^2= k^2 --- positive
Hence, the conjecture is true

Final answer:
The conjecture that for every integer n, the value of [tex]n^2[/tex] is positive is disproven by the counterexample of squaring zero, as 0 squared equals 0, which is not positive.
Explanation:
The conjecture for consideration is: For every integer n, the value of [tex]n^2[/tex] is positive.
To evaluate this conjecture, we need to look at the definition of integer squares. When we square any positive or negative integer, we multiply the number by itself, resulting in a positive product since a negative times a negative equals a positive. However, the conjecture overlooks the integer zero (0). When we square zero, 02, we get zero, which is neither positive nor negative. Thus, while the conjecture holds for all integers except zero, the case where n is zero provides a counterexample and disproves the original claim
To further illustrate this, let's consider a few examples:
Positive integer: [tex]3^2[/tex] = 9.Negative integer: [tex](-3)^2[/tex] = 9.Zero: 02 = 0 (Counterexample).Given that 0 is not a positive number, we can conclude that the conjecture does not hold true for every integer since it fails for n=0.
Dion had 25.00 he purchased the following items for his younger brother using his money. If the tax purchase was 1.85 how much money did dion have left?
he has 77 cents left
1.95*3=5.85
3.60*2=7.20
2.48*3=7.44
1.89+5.85+7.20+7.44+1.85=24.23
25-24.23=0.77
Dion has $23.15 left after taking into account all of his purchases as well as the tax.
Explanation:A simple subtraction issue from the subject of mathematics underlies this query. Dion started out with $25.00. We deduct this $1.85 from his initial sum to determine how much money Dion still has if he bought certain products and paid a tax of $1.85 on his purchases. Dion now has $23.15 left after subtracting $1.85 from the $25.00. This is an illustration of how you must deduct purchases and expenses from a total to determine the balance that is left.

Square roots of given perfect squares are 14, 5, 9. Two of given numbers are not perfect squares (75 and 200) and one number is not defined in this context (2).
Explanation:The square root of a number is a value that when multiplied by itself gives the original number. In other words, √a*b = a if and only if b=a*a. A perfect square is a number that is the square of a whole number. So, the task here is to find the numbers that are perfect squares and then find their square roots.
196 is a perfect square, as 14*14=196, so the square root is 14.
75 is not a perfect square so we do not need to find its square root.
Given '2' is not properly defined in this context, so we can't identify the square root.
25 is a perfect square, as 5*5=25, so the square root is 5.
81 is a perfect square, as 9*9=81, so the square root is 9.
200 is not a perfect square so we do not need to find its square root.

Hey there!!
Given equation :
A + B + C = D
and solve for B
In order to solve for the B, we will need to take all the other variables to the other side.
... A + B + C = D
Subtracting A on both sides.
... B + C = D - A
Subtracting C on both sides.
... B = D - A - C

A model airplane flies 18 feet in 2 seconds. What is the airplanes speed in miles per hour?
Answer:
6.1 miles per hour
Step-by-step explanation:
That is 9 feet per second.
There are 3600 seconds in an hour.
9 x 3600 is 32400
That is 32400 feet in an hour.
32400 feet is about 6.1 miles. (rounded)
The airplanes speed is 6.1 miles per hour.
The speed of the airplane will be 6.13 miles/hour. It is obtained by the unit conversion.
What is speed ?Speed is defined as the rate of change of the distance or the height attained. it is a time-based quantity. its si unit is m/sec.
Unit conversion;
1 ft/sec=0.681818 miles/hr
The speed in ft /sec;
v=d/t
v=18 feet/2 second
v=9 ft/sec
1 ft/sec=0.681818 miles/hr
9 ft/sec=9×0.681818 miles/hr
9 ft/sec=6.13 miles/hr
Hence, the speed of the airplane will be 6.13 miles/hour.

The O! Natural Company sells a juice in 1 gallon bottles. The current retail price of the juice is $3.50 for 1 gallon. In order to remain competitive, the company will decrease the price to $3.20. What percent of the original price are consumers going to pay?
Answer:
After the discount, the customer will pay only 91.4% of the initial price.
Step-by-step explanation:
We have that the price of the current retailer, in dollars, is:
3.50
After the discount, the new price, in dollars, is:
3.20
We want to know what percentage of the original price is the final price.
To find out, we must divide the final price between the initial price and then multiply the result by 100%
So:
[tex]\frac{ 3.20}{3.50}[/tex]*100% = 0.914. * 100% = 91.4%
After the discount, the customer will pay only 91.4% of the initial price.
The discount percentage you are going to pay is 100% -91.4% = 8.6% of the initial price

y=−2x+4
Complete the missing value in the solution to the equation.
(____,-2)
(3, - 2)
given y = - 2, then
- 2x + 4 = - 2 ( solve for x )
subtract 4 from both sides
- 2x = - 6 ( divide both sides by - 2 )
x = [tex]\frac{-6}{-2}[/tex] = 3
The coordinate that completes the solution to the equation is (3, -2)
Given the function y = -2x + 4
We are to find the value of x if y is -2
Substitute y = -2 into the function as shown:
-2 = -2x + 4
Subtract 4 from both sides
-2 - 4 = -2x + 4 - 4
-6 = -2x
x = 6/2
x = 3
Hence the coordinate that completes the solution to the equation is (3, -2)

sales tax on a $400 stereo is $16. What is the tax on a $650 TV?
The reason being is that we need to find it out of 100. So, we divide 400 by 4 and because we did that to the denominator we have to do it to the numerator so 16 divided by 4 is well 4. So we found out that is 4/100 we just divide that by 650 and we get 26.
TL;DR it’s $26
Tax is the price charged on an object. This shows that the tax on a $650 TV is $26
If the sales tax on a $400 stereo is $16, this can be written as:
$400 = $16
To get the sales tax on $650 TV, we can write;
$650 = x
x is the required tax;
Divide both expressions to have:
[tex]\frac{400}{650} =\frac{16}{x} \\400x = 16 \times 650\\400x = 10400\\x = \frac{10400}{400}\\x= \$26[/tex]
This shows that the tax on a $650 TV is $26

Ricardo would swim a farther distance in 1 hour. By taking the number of miles he swam and in the fraction of the hour, you can find the answer.
Divide 5 1/4 by 3 because it took 3/5 of an hour to swim that far. That would lead to 1 3/4 for 1/5 of an hour. Now that we know this, we can multiply 1 3/4 to 5 to get how much he would swim in 1 hour which is 8 3/4
Divide 4 1/2 by 5 because it took 5/9 of an hour to swim that far. That would lead to 9/10 for 1/9 of an hour. Now that we know this, we can multiply 9/10 to 9 to get how much he would swim in 1 hour which is 8 1/10
Since 8 1/10 is less than 8 3/4, Ricardo swam farther
