The required ladder reaches approximately 12.37 feet up the wall.
What is the Pythagorean theorem?The Pythagorean theorem is a fundamental theorem in geometry that describes the relationship between the sides of a right triangle. It states that in a right triangle, the square of the length of the hypotenuse (the side opposite the right angle) is equal to the sum of the squares of the lengths of the other two sides. In algebraic terms, the Pythagorean theorem can be written as:
a² + b² = c²
where a and b are the lengths of the two legs of the right triangle, and c is the length of the hypotenuse.
Here,
We can use the Pythagorean theorem to solve this problem. Let's denote the distance from the bottom of the wall to where the ladder reaches the wall as h. Then we have,
h² + 4² = 13²
h² + 16 = 169
h² = 153
h ≈ 12.37
Therefore, the ladder reaches approximately 12.37 feet up the wall.

A store is advertising a sale with 10% off all items in the store. The sales tax is 5%. A 55-inch
television is regularly priced at $855. What is the total price of the television, including sales tax,
if it was purchased on sale?
Answer:
$812.25
Step-by-step explanation:
Given data
Cost of TV= $855
Discount= 10%
Tax= 5%
Let us find the amount of the Discount
=10/100*855
=0.1*855
=$85.5
Let us find the amount of the Tax
=5100*855
=0.05*855
=$42.75
Hence the cost of the TV is
=855+42.75-85.5
=897.75-85.5
=$812.25

Answer:
258 cm PLZ GIVE ME BRAINLIEST
Step-by-step explanation:
Since the chord is given as 80cm, we know from the definition of a chord that it is equidistant to both sides of the circle. Therefore, half the chord is 40. The extension of the center to the chord is perpendicular to the chord(definition of a chord). Therefore, if we connect the center of the circle to the edge of the chord, it's a right triangle. Also the center of the chord is the radius of the circle. Pytharogean theorem: 40^2 + 9^2=r^2 : 1681=r^2: r=41. The radius is 41. Curcumference of circle: pi*2*r : pi*2*41 : pi*82= 258 cm.

The list that represents the values of x for which the function has a discontinuity is 0 and 1
How to determine the list of values?The function is given as:
[tex]f(x)=\dfrac{1}{x(x-1)}[/tex]
Start by setting the denominator to 0
x(x -1) = 0
Split the equation
x = 0 and x -1 = 0
Solve for x
x = 0 and x = 1
Hence, the list that represents the values of x for which the function has a discontinuity is 0 and 1.

You bought an item for $25 on Ebay and plan on marking it up 65%. What price will you sell your item for to the nearest dollar?
Answer:
$41.25
Step-by-step explanation:
The original price is $25. You want to sell it for 65% more. To find this amount, we need to find 65% of 25.
Let's make an equation.
65/100 • 25 = x
Multiply.
x = 16.25
Now we know how much you want to mark it up by.
Add this to your base of $25.
25 + 16.25
= 41.25
You want to sell it for $41.25.
Hope this helps!

Answer: 55 Square inches
Step-by-step explanation:
You should find the area of the square and rectangle separately
To find the area you multiply length times width, so the area of the square is 4×4 which equals 16
Then you do the same to the rectangle, 13×3=39
To find the area of the whole figure you add the area of the two shapes together 16+39 which should give you 55

x2-7x+12byx-3 divide of algebraic expression
Answer:
x - 4
Step-by-step explanation:
Please write X2-7x+12 by x-3 as x^2 - 7x + 12. The " ^ " represents exponentiation.
Notice that x^2 - 7x + 12 factors as follows: (x - 3)(x - 4), and so the original division problem
x^2 - 7x + 12 (x - 3)(x - 4)
-------------------- becomes -------------------- = x - 4
x - 3 x - 3
for all x except x = 3 (because we cannot divide by zero).

Help me with this please!!!!!!
Answer:
V = (4, 4 )
Step-by-step explanation:
Use the midpoint formula, the equation corresponding coordinates to the coordinates of the midpoint M
let V = (x, y ) , W = (8, 6 ) , then
[tex]\frac{x+8}{2}[/tex] = 6 ( multiply both sides by 2 )
x + 8 = 12 ( subtract 8 from both sides )
x = 4
and
[tex]\frac{y+6}{2}[/tex] = 5 ( multiply both sides by 2 )
y + 6 = 10 ( subtract 6 from both sides )
y = 4
coordinates of V = (4, 4 )
Lines RS, TV, and SW are shown. On a coordinate plane, 3 lines are shown. Line R S goes through (negative 8, 6) and (2, 6). Line T V goes through (negative 6, negative 4) and (8, negative 4). Line S W goes through (2, 6) and (2, negative 8). Which statements are true about these lines? Select three options. Line RS has a slope of 6. Line SW has an undefined slope. Line TV has a slope of 0. Lines RS and TV are parallel. Line SW is perpendicular to line RS, but not to line
Answer:
b, c, d.
Step-by-step explanation:
Statements 2) Line SW has an undefined slope, 3)Line TV has a slope of 0, and 4) Lines RS and TV are parallel are correct.
It is given that there are three lines RS, TV, and SW.
Line RS goes through (-8, 6) and (2, 6).
Line TV goes through (-6, -4) and (8, -4).
Line SW goes through (2, 6) and (2,-8).
It is required to find true statements.
Statements are:
Line RS has a slope of 6.Line SW has an undefined slope.Line TV has a slope of 0.Lines RS and TV are parallel.Line SW is perpendicular to line RS, but not to line TV.What is a straight line?A straight line is a combination of endless points joined on both sides of the point.
The slope 'm' of any straight line is given by:
[tex]m=\frac{y_{2}-y_{1}}{{x_{2}-x_{1}}}[/tex]
Where [tex](x_{1}, y_{1}) and (x_{2}, y_{2})[/tex] are points lie on the line.
1. Finding line RS slope by using the above formula:
[tex]m=\frac{6-6}{2-(-8)}[/tex]
[tex]m=0[/tex]
2. similarly finding line SW slope:
[tex]m=[/tex] ∞
3. similarly finding line TV slope:
[tex]m=0[/tex]
4. If the two lines are parallel then their slope will be equal.
The slope of RS = The slope of TV.
Hence RS and TV are parallel.
5. If two lines are perpendicular then their product of slope will be -1.
Here we can see the product of the slope of SW and RS is not defined.
Hence these two lines aren't perpendicular.
Therefore, statements 2, 3, and 4 are correct.

Answer:
473 yd^3
Step-by-step explanation:
The surface area of the square base is (11 yd)^2, or 121 yd^2.
The surface area of one of the slanting sides of the pyramid is
A = (1/2)(b)(h), which comes to A = (1/2)(11 yd)(16 yd) = 88 yd^2.
Thus, four such sides have a combined surface area of 352 yd^2.
Combining the surface areas of the slanting sides with the base area yields 473 yd^3

what is the equation of the line that passes through the points -7 -1 and has a slope of 1
Answer:
Step-by-step explanation:
y - y1 = m (x - x1) the slope m = 1 (x1, y1) = (-7, -1)
y - -1 = 1 (x - -7)
y + 1 = 1 (x + 7)
