Leg= 8
Leg=x-4
Hypotenuse=8
The value of x is 10 if Leg= 8 and Leg=x-4.
What is Pythagoras theorem?This states that “In a right-angled triangle, the square of the hypotenuse side is equal to the sum of squares of the other two sides“.
In this scenario we were given
Leg= 8
Leg=x-4
Hypotenuse=x
Therefore : x² = 8² + (x-4)²
x² = 64 + x² - 8x + 16
x² - x² = 80 - 8x
8x = 80
x = 80/8 = 10
Therefore hypotenuse is 10 and the length of the other side is (10-4) = 6.

The linear equation that gives the rule for the given table x 0 1 2 3 y 0 2 4 6 is y = 2x.
What is linear equation?A linear equation is an equation of a straight line in the form of y = mx + b, where m represents the slope of the line, and b represents the y-intercept.
The slope of the linear equation can be found by calculating the change in y over the change in x:
slope=(y2 - y1) / (x2 - x1)
Taking (x1,y1) = (0,0) and (x2,y2) = (3,6),
slope=(6 - 0) / (3 - 0)
= 2
So slope of the linear equation is 2.
Next, we can use the point-slope form of the linear equation to find the equation of the line:
y - y1 = m(x - x1)
Taking (x1,y1) = (0,0) and m = 2,
y - 0 = 2(x - 0)

Jen has driven 15 miles on her way to the mall. this distance is 3/5 of the total distance. if d represents the total distance in miles, which equation can be used to find d
This can be resolved with d = 25 miles by multiplying equation both sides by
Which equation can be used to find d?If Jen has driven 15 miles, and this is 3/5 of the total distance, we can use the following equation to find the total distance d:
15 = (3/5) * d
To solve for d, we need to isolate it on one side of the equation. We can start by dividing both sides of the equation by 3/5, which is the same as multiplying by its reciprocal, 5/3:
15 * (5/3) = d
Simplifying the expression on the left side, we get:
25 = d
Therefore, the total distance Jen needs to travel to get to the mall is 25 miles.
In summary, the equation that can be used to find the total distance d, given that Jen has driven 15 miles and this is 3/5 of the total distance, is:
15 = (3/5) * d
Which can be solved for d by multiplying both sides by 5/3, giving:
d = 25 miles
In conclusion, assuming that Jen has driven 15 miles, which is 3/5 of the entire trip, the equation that can be used to determine the whole distance d is:
15 = (3/5) * d

What is a Variable?A variable is anything that may be altered in the context of an experiment or mathematical idea. A single symbol is frequently used to denote a variable. Generic symbols for variables are the letters x, y, and z. Variables are qualities with a wide range of values that may be investigated. These include characteristics like height, age, wealth, place of birth, academic standing, and kind of residence, to mention a few. The two primary groups of variables can be separated using numerical and categorical approaches.
Let's define the variables first:
Let's call John's sales of notebooks "n" the quantity.
Each notebook costs $1.50, hence the whole profit from notebook sales is $1.50.
John earned a total of $92.50, according to the issue, thus we can create the following equation:
$40.00 + 1.5n = $92.50
Now that "n" is solved, we can:
$1.5n = $92.50 - $40.00
$1.5n = $52.50 \sn = 35
John consequently sold 35 notepads.

What are functions ?
Function, in mathematics, an expression, rule, or law that defines a relationship between one variable (the independent variable) and another variable (the dependent variable).
What are asymptotes ?
An asymptote is a straight line that constantly approaches a given curve but does not meet at any infinite distance. In other words, Asymptote is a line that a curve approaches as it moves towards infinity.
An asymptote of the curve y = f(x) or in the implicit form: f(x,y) = 0 is a straight line such that the distance between the curve and the straight line lends to zero when the points on the curve approach infinity.
There are three types of asymptotes namely:
1) Vertical Asymptotes
2) Horizontal Asymptotes
3) Oblique Asymptotes
The point to note is that the distance between the curve and the asymptote tends to be zero as it moves to infinity or -infinity.

What is the total cost of a $707 tablet computer that is on sale at 14% off if the local sales tax rate is 5%?
Answer:
$638.42
Step-by-step explanation:
First, we need to calculate the sale price of the tablet computer after the 14% discount is applied. To do this, we can multiply the original price by 0.86 (1 - 0.14), which gives:
Sale price = $707 x 0.86 = $608.02
Next, we need to add the sales tax to the sale price. To do this, we can multiply the sale price by 0.05 (5%), which gives:
Sales tax = $608.02 x 0.05 = $30.40
Finally, we can find the total cost of the tablet computer by adding the sale price and the sales tax, which gives:
Total cost = $608.02 + $30.40 = $638.42
Therefore, the total cost of the tablet computer with the discount and sales tax included is $638.42.

For what value of k will V= x+ k/x have a relative minimum at x = 3?
The value of k will make V = x + k/x have a relative minimum at x = 3 is k = 9
What is a relative minimum?A relative minimum of a function is the minimum value of the function in a particular interval.
Since we have the function V = x + k/x. We desire to find the value of k that will make V = x + k/x have a relative minimum at x = 3
So, to find the relative minimum of V, we differentiate with respect to x and equate to zero.
So, V = x + k/x
dV/dx = d(x + k/x)/dx
= dx/dx + kd(1/x)/dx
= 1 - k/x²
Equating dV/dx to zero, we have that
dV/dx = 0
⇒ 1 - k/x² = 0
1 = k/x²
k = x²
For a relative minimum at x = 3, substitute x = 3 into the equation. So, we have that
k = x²
= 3²
= 9
So, k = 9

If Jenny has 50 square tiles and arranges them in a rectangular array with 4 rows, then she would have a total of 48 tiles, with 2 tiles left over.
How to find the number of tilesIf Jenny arranges the tiles in a rectangular array with 4 rows, this means each row will have 50/4 = 12.5 tiles. However, since we cannot have half a tile, we need to round down to the nearest whole number, which is 12.
Therefore, each row will have 12 tiles, and the total number of tiles used will be 4 x 12 = 48. To find out how many tiles are left over, we need to subtract the total number of tiles used from the original number of tiles: 50 - 48 = 2. So, there will be 2 tiles left over.

In a group of 15 children, 5 said they are an only child, 3 said they have 1 sibling only, 4 said they have exactly 2 siblings, and 3 said they have exactly 3 siblings.
What is the average number of siblings for this group?
Enter your answer as a decimal, rounded to the nearest tenth, in the blank.
Answer:
1.3
Step-by-step explanation:
To find the average number of siblings for the group, we need to calculate the total number of siblings and divide by the total number of children.
Out of the 15 children:
5 are only children, so they have 0 siblings each.
3 have 1 sibling each, so there are 3 * 1 = 3 siblings in total.
4 have 2 siblings each, so there are 4 * 2 = 8 siblings in total.
3 have 3 siblings each, so there are 3 * 3 = 9 siblings in total.
The total number of siblings is 0 + 3 + 8 + 9 = 20.
The average number of siblings for the group is 20/15 = 1.3 (rounded to the nearest tenth).
Therefore, the average number of siblings for this group is 1.3.
