A builder places a 2.9m ladder on horizontal ground, resting against a vertical wall. to be safe to use, the base of this ladder must be 1.3m away from the wall. how far up the wall does the ladder reach? GIve ur answer to 1 decimal place

Answers

Answer 1
The answer is in the photo
Answer 2

The length up the wall does the ladder reach is 2.59 meter

What is Pythagorean theorem?

In mathematics, the Pythagorean theorem, or Pythagoras' theorem, is a fundamental relation in Euclidean geometry among the three sides of a right triangle.

What is Right triangle?

A right triangle or right-angled triangle, or more formally an orthogonal triangle, is a triangle in which one angle is a right angle or two sides are perpendicular.

Given,

Length of the ladder = 2.9 meter

Distance from base to wall = 1.3 meter

Draw the figure using the given data

Apply Pythagorean theorem

[tex]AB^{2}+BC^{2}= AC^{2}\\ AB^{2}=AC^{2}-AC^{2} \\ AB^{2}=2.9^{2}-1.3^{2}\\ AB^{2}=6.72\\ AB=\sqrt{6.72}[/tex]

AB=2.59 meter

Hence, the length up the wall does the ladder reach is 2.59 meter

Mel took out a loan of $40,000 at 14 percent on March 16, 2015 which will be due on January 9, 2016. Using exact interest the amount of Mel's interest cost is:

Answers

Answer:

the interest cost is $4,679.45

Step-by-step explanation:

The computation of the interest cost is shown below:

= Loan amount × rate of interest × given no of days ÷ total no of days in a year

= $40,000 × 14% × 305 days ÷ 365 days

= $4,679.45

hence, the interest cost is $4,679.45

A system of linear equations contains two or more equations, for example: y = 0.5x + 2 and y = x-2. The solution of such a system is the ordered pair which is a solution to both equations. To solve a system of linear equations graphically, we graph both equations in the same coordinate system.

3(5x - 6) = 6(2x - 12)

Answers

Answer:

x = -18

Step-by-step explanation:

Distribute: 3*5x = 15x ; 3*-6 = -18 ; 6*2x = 12x ; 6*-12 = -72

15x - 18 = 12x - 72

Add 18 to both sides: 15x = 12x - 54

Subtract 12x from both sides: 3x = -54

Divide both sides by 3: x = -18

Answer:

x= 17.666666...

Step-by-step explanation:

3(5x - 6) = 6(2x - 12)

(3 times 5x , 3 times  -6)             (6 times 2x, 6 times - 12)

15x-18 = 12x -72           (multiply insides)

-12x       -12x              (remove 12x from right side)

3x-19 = -72                (product)

   +19 = +19                (add 19 left side to remove it)

3x = 53                        (product)

x = [tex]\frac{53}{3}[/tex]                              (divide)

x= 17.666666...                (answer)

x = 17.67                     (if simplify)

Answers

Answer:

[tex] a_{n} = (6){3}^{n - 1} [/tex]

Step-by-step explanation:

6, 18, 54

First, recognize that this is a geometric sequence. To find the common ratio, divide the f

second term by the first term.

18/6 = 3

Check this with the second and third term.

54/18 = 3

Your common ratio is 3.

An explicit formula for a geometric equation is:

[tex] a_{n} = a_{1} {r}^{n - 1} [/tex]

We know the first term is 6 and the common ratio is 3. Plug in these values.

[tex] a_{n} = (6) {3}^{n - 1} [/tex]

This is your formula.

simone buys a painting for 24000 later she sells it for 60000 how much is her percentage profit

Answers

Answer:

percentage profit = 150%

Step-by-step explanation:

percentage profit = sp - cp/cp * 100

sp is the selling price = 60000

cp is the cost price = 24000

percentage profit = 60000-24000/24000 * 100

percentage profit = 36000/24000 * 100

percentage profit = 36000/240

percentage profit = 150%
