A wall is 22 feet tall. A ladder is leaned against that wall. The top of the ladder touches the top of the wall and the bottom of the ladder rests on the ground 8 feet from the base of wall. What is the length of the ladder?
Answer:
23.41 feet
Step-by-step explanation:
The ladder forms a right angle triangle with the wall
Height of the wall (opposite) = 22 feet
Bottom of the ladder from the wall (adjacent) = 8 feet
What is the length of the ladder?
Length of the ladder (hypotenuse)
Using Pythagoras theorem
Hypotenuse ² = opposite ² + adjacent ²
= 22² + 8²
= 484 + 64
= 548
Hypotenuse ² = 548
Hypotenuse = √548
= 23.41 feet
The length of the ladder is 23.41 feet

You want to tile a 10 foot square floor with tiles that are twice as long as they are wide. determine how many tiles you need to cover the floor when the tile length is 2 feet
To cover a floor with an area of 10 square foot, 5 tiles is needed.
Area is the amount of space enclosed by a two-dimensional figure.
If the tile is 2 feet long and twice as long as they are wide, suppose that the tile is a rectangle, then the area of each tile will be:
Area of tile = l x w
where l = 2 feet
w = 1 foot
Area of tile = 2feet(1 foot)
Area of tile = 2 ft^2
To determine how many tiles are needed to cover a 10 foot square floor, divide the area of the floor with the area of each tile.
# of tiles = Area of floor/Area of each tile
# of tiles = 10 ft^2/2ft^2
# of tiles = 5

Find the minimum value of the function. [Hint: Let t = x³.] f(x) = 1 + 12x³ + 3x⁶
===========================================
Work Shown:
t = x³
f(x) = 1 + 12x³ + 3x⁶
f(x) = 1 + 12x³ + 3(x³)²
f(t) = 1 + 12t + 3t²
f(t) = 3t² + 12t + 1
f(t) = 3(t² + 4t) + 1
f(t) = 3(t² + 4t + 4 - 4) + 1 .... see note below
f(t) = 3( (t²+4t+4) - 4) + 1
f(t) = 3( (t+2)² - 4) + 1
f(t) = 3(t+2)² - 3*4 + 1
f(t) = 3(t+2)² - 12 + 1
f(t) = 3(t+2)² - 11
The smallest that t² can get is 0. By extension, the smallest (t+2)² can get is also 0, and same goes for 3(t+2)².
So effectively we replace the 3(t+2)² portion with 0 and end up with 3(t+2)²-11 = 0-11 = -11 as the minimum value of f(x)
This is the smallest output possible. Confirmation of such is shown in the graph below.
------------
Note: Recall that (A+B)² = A²+2AB+B². If we use this rule on (t+2)², then we get t²+4t+4. Earlier we simply had t²+4t without the extra +4 at the end. So I added 4 and subtracted 4 to balance things out. This completed the square.
Find the equation of the line that passes through the following points. Write the equation in slope-intercept form.
(-4.-8) and (-8, -9)
Answer:
The equation in the slope-intercept form will be:
y = 1/4x - 7
Step-by-step explanation:
Given the points
(-4.-8) (-8, -9)[tex]\mathrm{Slope}=\frac{y_2-y_1}{x_2-x_1}[/tex]
[tex]\left(x_1,\:y_1\right)=\left(-4,\:-8\right),\:\left(x_2,\:y_2\right)=\left(-8,\:-9\right)[/tex]
[tex]m=\frac{-9-\left(-8\right)}{-8-\left(-4\right)}[/tex]
[tex]m=\frac{1}{4}[/tex]
We know that the slope-intercept of line equation is
[tex]y=mx+b[/tex]
where m is the slope and b is the y-intercept
substituting m = 1/4 and the point (-4, -8) to find the y-intercept 'b'
y = mx+b
-8 = 1/4(-4)+b
-8 = -1 + b
b = -8+1
b = -7
so the y-intercept = b = -7
substituting m = 1/4 and b = -7 in the slope-intercept form of line equation
y = mx+b
y = 1/4x + (-7)
y = 1/4x - 7
Thus, the the equation in slope-intercept form will be:
y = 1/4x - 7

Aidan's average speed on his drive home is 26 2/3 miles per hour
What is Aidan's average speed?
Average speed is the total distance travelled per time. It indicates how fast an object is moving.
Average speed = total distance / total time
The first step is to determine the time it would take Aidan to drive to school :
Time = distance / speed
16 / 40 = 2/5 hours = 2/5 x 60 = 24 minutes
The second step is to determine the time it would take Aidan to drive from school
Time it would take to drive home from school = 60 minutes - 24 minutes = 36 minutes = 36/60 = 3/5 hours
Aidan's average speed to drive home = 16 miles ÷ 3/5
16 x 5/3 = 80 / 3 = 26 2/3 miles per hour

The answer is C.
Step-by-step explanation:
In order to find the x-intercept and y-intercept, you have to substitute 0 into each expression :
[tex]let \: x = 0[/tex]
[tex]0 - 3y = 6[/tex]
[tex] - 3y = 6[/tex]
[tex]y = 6 \div ( - 3)[/tex]
[tex]y = - 2[/tex]
[tex]let \: y = 0[/tex]

Which ratio is equivalent to the ratio 20 to 35? 5 to 7 7 to 5 8 to 14 14 to 8
Answer: it’s 8 to 14 number c
Step-by-step explanation:
Let me know if I’m wrong
The ratio equivalent to 20 to 35 is 8 to 14.
Option C is the correct answer.
What is a ratio?The ratio shows how many times one value is contained in another value.
Example:
There are 3 apples and 2 oranges in a basket.
The ratio of apples to oranges is 3:2 or 3/2.
We have,
20 to 35
This can be written as,
= 20/35
= 5 x 4 / 5 x 7
= 4/7
Now,
5 to 7 = 5/7
7 to 5 = 7/5
8 to 14 = 8/14 = 4/7
14 to 8 = 14/8 = 7/4
Thus,
20 to 35 is the same as 8 to 14.

Consider the similar triangle below.
ABC is the per-image and PQR is the image.
Answer:
Scale factor: 2
PR = 14
Perimeter = 34
Step-by-step explanation:
Similar Triangles
Similar triangles are those who have their corresponding side lengths proportional, i.e. the ratio of the corresponding sides is equal.
The figure shows similar triangles ABC and PQR. We can also see corresponding sides BC and QR have lengths 6 and 12 respectively.
The scale factor is [tex]\frac{12}{6}=2.[/tex]
The rest of the sides can be calculated by using the per-image triangle ABC side lengths and the new-found scale factor. Thus:
PR = AC*2 = 7*2 = 14
PR = 14
PQ = AB*2 = 4*2 = 8
The perimeter of the triangle PRQ is the sum of its side lengths:
P = 12 + 14 + 8 = 34
Answers:
Scale factor: 2
PR = 14
Perimeter = 34
Write 142% as a mixed number in simplest form.

Both numbers are even. Divide by two.
71 50
Can't be simplified any further
Make it a mixed number.
1 21/50
The number 142 % in mixed number form is 1 21/50
What are Mixed Numbers?
A mixed number is a whole number, and a proper fraction represented together. A mixed number is formed by combining three parts: a whole number, a numerator, and a denominator. The numerator and denominator are part of the proper fraction that makes the mixed number.
Given data ,
The number given is = 142 %
On simplifying , we get
142 % = 100 % + 42%
We know that 100 % = 1
So ,
42 % = 42 / 100
Divide by 2 on both numerator and denominator , we get
21 / 50
So , the number 142 % is written as 1 21/50
Or ,
Simplifying 142 / 100 , we get
142 / 100 = 71 / 50
Converting 71 / 50 into mixed number , we get 21 as the remainder ,
Therefore , the mixed number form of 71 / 50 is 1 21/50
Hence , the mixed number form is 1 21/50
