The distance from the bottom of a ladder to the wall it leans against is one-fourth of the length of the ladder. If the ladder is 12 feet long, how far up the wall will the ladder extend?

Answers

Answer 1

Answer:

The ladder will extend 11.6ft up the wall

The Distance From The Bottom Of A Ladder To The Wall It Leans Against Is One-fourth Of The Length Of
Answer 2

Wall will the ladder extend 11.6 ft

What is Pythagoras theorem?

The Pythagoras theorem states that in a right-angled triangle, the square of the hypotenuse is equal to the sum of the squares of the other two sides.

Given

Length of the ladder = 12 ft

Distance from the bottom = 1/4 of length of the ladder

= [tex]\frac{1}{4}[/tex] × [tex]12[/tex]

= 3 ft

By using Pythagoras theorem

[tex]12^{2}=x^{2} +3^{2}[/tex]

[tex]x^{2} =144-9[/tex]

[tex]x^{2} =135[/tex]

[tex]x=\sqrt{135}[/tex]

[tex]x=[/tex] ± 11.6 ft

Hence, wall will the ladder extend 11.6 ft.

What are Arithmetic operations?

Arithmetic operations can also be specified by subtracting, dividing, and multiplying built-in functions.

The operator that performs the arithmetic operation is called the arithmetic operator.

Operators which let do a basic mathematical calculation

+ Addition operation: Adds values on either side of the operator.

For example 12 + 2 = 14

- Subtraction operation: Subtracts the right-hand operand from the left-hand operand.

for example 12 -2 = 10

* Multiplication operation: Multiplies values on either side of the operator

For example 12*2 = 24

/ Division operation: Divides left-hand operand by right-hand operand

For example 12/2 = 6

To determine missing values in the magic squares,

Apply the arithmetic operations in the rows and columns,

The sum of each row = 9

The sum of each column = 9

The sum of each diagonal = 9

Here the first grid :

0        7         2

5         3        1

c. car color is a continuous variable
d. frequency is a discrete variable

thank ya so much and have a lovely day!!​

Answers

Answer:

B

Step-by-step explanation:

Color of car is a categorical variable. its value are not numerical

The frequency of cars entering the parking lot is a discrete variable so option (d) will be correct.

What is a variable?

A variable in mathematics is a representation of any quantity whose value is changeable.

For example speed of a vehicle is a variable.

The value of the variable changes but the meaning of the variable never for example speed of vehicle changes but the word speed does not change.

A discrete variable is a variable whose values are different.

Since car color is not a variable because the meaning of variable is not constant in car color.

The frequency of vars is a discrete variable because it is different for each kind of car.

Hence "The frequency of cars entering the parking lot is a discrete variable".

Answer:

[tex]\Large\boxed{\text{Perpendicular Equation:} \ y = -\frac{2}{7}x + \frac{22}{7}}[/tex]

[tex]\Large\boxed{\text{Parallel Equation:} \ y = \frac{7}{2}x -12}[/tex]

Step-by-step explanation:

In order to find the equations that are parallel/perpendicular to the line [tex]y = \frac{7}{2}x - 4[/tex], we need to note a couple things about the relationships between lines and their parallel/perpendicular lines.

A) If a line is perpendicular to another, the slopes will be opposite reciprocals (for instance [tex]-2[/tex] and [tex]\frac{1}{2}[/tex] - multiplied, they equal -1.)B) If a line is parallel to another, they will have the exact same slope.

Perpendicular:

We know that the slope of a perpendicular line will be the the opposite reciprocal of the line we're comparing it to.

Since the slope of our base line is [tex]\frac{7}{2}[/tex], we can find the reciprocal, then the opposite of that.

Reciprocal of [tex]\frac{7}{2} = \frac{2}{7}[/tex] Opposite of [tex]\frac{2}{7} = -\frac{2}{7}[/tex]

So the slope of this line will be [tex]-\frac{2}{7}[/tex], making our equation [tex]y = -\frac{2}{7}x+ b[/tex]

However, y-intercepts will not stay the same. In order to find this, we can substitute the point (4, 2) into our equation to solve for b.

[tex]2 = -\frac{2}{7} \cdot 4 + b[/tex] [tex]2 = -\frac{8}{7} + b[/tex] [tex]b = 2+\frac{8}{7}[/tex] [tex]b = 2 \frac{8}{7}[/tex] [tex]b=\frac{22}{7}[/tex]

Now we know the y-intercept of this equation is [tex]\frac{22}{7}[/tex]. We can now finish off our equation of the line by substituting that in to what we already have,  [tex]y = -\frac{2}{7}x+ b[/tex].

[tex]y = -\frac{2}{7}x+ \frac{22}{7}[/tex]

Parallel:

As mentioned earlier, parallel lines will have the exact same slope but not the same y-intercept. Since the slope of our original equation is [tex]\frac{7}{2}[/tex], the slope for this one will also be [tex]\frac{7}{2}[/tex].

So we now know the equation looks something like [tex]y = \frac{7}{2}x + b[/tex].

In order to solve for b, we apply the same logic we did in the perpendicular line and substitute in the point (4, 2) into the equation.

[tex]2 = \frac{7}{2} \cdot 4 + b[/tex] [tex]2 = \frac{28}{2}+b[/tex] [tex]2 = 14+b[/tex] [tex]b = 2-14[/tex] [tex]b =-12[/tex]

Now that we know the slope and the y-intercept, we can finish off our equation as [tex]y = \frac{7}{2}x -12[/tex].

Hope this helped!

4(5)=20

Hey there!

s + s + s + s + 12

= 1s + 1s + 1s + 1s + 12

= 2s + 2s + 12

= 4s + 12


So, we’re looking for something that’s equivalent to: 4s + 12



• Option A.
4s + 3 ≠ 4s + 12

Option A. is wrong because it is NOT equivalent to the given equation

• Option B.
4(s + 3)

= 4(s) + 4(3)

= 4s + 12

Thus, this mean Option B. could possibly be your answer.

• Option C.

4s(s + 3)

= 4s(s) + 4s(3)

= 4s(s) + 3(4s)

= 4s^2 + 12s

Option C. is wrong because it is NOT equivalent to the given equation as well.

• Option D.
4 + s + 12

COMBINE the LIKE TERMS

= 16 + s

= s + 16

Option D. is wrong because it isn’t equivalent to the given equation as well.

Therefore, your answer is:

Option B. 4(s + 3)
