The longest side of a right triangle is 15 feet. The third side is 15 less than three times the shortest side. Find the length of the shortest side.

Answers

Answer 1

Answer: The shortest side is 9ft

Step-by-step explanation: If the longest side is identified as 15 ft, then we already have our hypotenuse (the longest side in a right angled triangle).

If the shortest side is labelled as x, then the third side of the triangle would be labelled as 3x - 15 (15 less than three times the shortest side).

Now we have three sides of a triangle which we can label as 15, x and 3x - 15

By applying the Pythagoras theorem, AC² = AB² + BC²

(Where AC is the hypotenuse and AB and BC are the other two sides)

15² = X² + (3x-15)²

By expansion, (3x-15)² becomes 9x² - 90x + 225

Hence, 225 = X² + 9X² - 90X + 225

225 = 10X² - 90X + 225

Subtract 225 from both sides of the equation

10X² - 90X = 0

Factorize the left hand side of the equation by 10x

10x (x - 9)= 0

Therefore, either

10x = 0 OR

x - 9 = 0

If 10x=0, then x=0. OR

If x - 9 = 0, then x = 9

The length of the shortest side is 9ft.

A system of linear equation consists of two or more linear equations with the two or more same variables. Such equations are called system of equations (or) simultaneous equations (or) a pair of equations.

Example:

x + y = 5 is one linear equation.

2x – y = 4 is another linear equation.

But x + y = 5, 2x – y = 4 together they form system of linear equation.

To illustrate the importance of outliers, suppose you do not count the owner in the last problem. The data for the other
workers is:
$ US
5 people earn $25,000, 3 earn $27,000, and 1 earns $34,000
What is the mean salary and standard deviation (to the nearest dollar) of the workers?

Answers

Answer:

The mean is 26666.67 and the standard deviation is 372919430.33.

Step-by-step explanation:

The mean means the average of the numbers.

The mean will be [tex]\frac{25000\times5 + 27000\times3 + 34000}{5 + 3 + 1} = \frac{240000}{9} = 26666.666666666[/tex].

The differences of the earnings from the mean are 1666.67, 26997.33, 33997.33.

Squaring the numbers we get, 2777788.89, 728855827.13, 1155818447.12.

We need to find the mean of the above numbers to get the standard deviation.

Thus, the standard deviation is [tex]\frac{2777788.89\times5 + 728855827.13\times3 + 1155818447.12}{9} = 372919430.33[/tex].

The perimeter of the square can be represented by the expression 36x+44 robin wants to write an equivalent expression for the perimeter that shows the side length of the square

Answers

Answer:

4  (9 x + 11) is an equivalent expression for the perimeter that shows the side length of the square is  (9 x + 11).

Step-by-step explanation:

Here, given The perimeter of the square  = (36 x+44)

Now,as we know :

PERIMETER OF SQUARE = 4 x ( SIDES)

Simplifying the perimeter expression.

Take 4 common out of the expression (36 x+44), we get:

(36 x+44) =  4 (9 x + 11)

⇒ Perimeter of the square  =  4 x  (9 x + 11)

4 x ( SIDES) = 4 x (9 x + 11)

⇒ Each Side = (9 x + 11)

Hence, 4 x (9 x + 11) is an equivalent expression for the perimeter that shows the side length of the square is  (9 x + 11).

The Midpoint Theorem states that "the segment joining two sides of a triangle at the midpoints of those sides is parallel to the third side and is half the length of the third side".

AE = EC .....Given

Therefore E is the Mid Point of AC.

BF = FC .....Given

Ibuki factored 12 xZ as (4x) (3x4)
Melodie factored 12x7 as (2x (6x)
Who factored correctly?

Answers

Final answer:

Neither Ibuki nor Melodie factored 12x² correctly based on the expressions given. However, if Melodie's (2x)(6x) was meant for 12x², then her factorization would be correct.

Explanation:

The students are attempting to factor the expression 12x². Factoring is the process of finding two or more expressions that multiply together to get the original expression. Ibuki's factorization of 12x² as (4x)(3x⁴) contains an error since 3x⁴ would imply raising x to the fourth power, which is not present in the original expression. Melodie's factorization of 12x² as (2x)(6x) is also incorrect since when you multiply 2x and 6x, you get 12x², not 12x⁷ as her expression suggests. The correct factorization of 12x² is (2x)(6x) since 2x multiplied by 6x equals 12x².

In summary, neither student has factored the expression correctly. However, if we take Melodie's answer as a typo and she meant (2x)(6x) for 12x², then her factored form would be correct.

explain why triangles LMN and NOP are similar

Answers

To prove the two triangles to be similar, it is enough to prove that they have 3 equal angles.
First :
Second :
Third : for the same latter reason, the two angles
Thus we conclude that the 2 triangles MLN and PNO are similar.

Note : if you realized that alternate angles form a letter “ Z “ shape, use this method to easily find them but don’t forget that the alternate angles are equal only when the lines cut by the same third line are parallel.

To find MO : since the two triangles MNL & PNO are similar thus the ratio of the sides facing the angle of common ( equal value ) is equal.
Thus :
ratio of PO/ML = ratio of of PN/NL = ratio of ON/NM

And then we solve :

PO/ML = ON/NM

Substitute the segments by their values :

15/6 = ON/5

Find ON = 12.5 cm

But MO = MN + NO

MO = 5 + 12.5 = 17.5 cm

The camera was $824.99 but I had to pay the additional 10% tax. What did I pay in total for my camera?

Answers

Answer:

$907.489

Step-by-step explanation:

Cost of camera : $824.99

Tax = 10%

tax on camera = 824.99 x 10 /100 = 82.499

total amount to be paid = cost + tax

$824.99 + $82.499 = $907.489

Answer:

$907.49

Step-by-step explanation:

Figure out what 10% of 824.99 is. You should get 82.499 which you round up to the nearest hundredth because this is money which gives you 82.50.

824.99+82.50=907.49

Andrew and Elena knew that after 28 days they would have 2^28 coins, but they wanted to find out how many coins that actually is Andrew wrote: 2^28=2×28=56. Elena said, " No, exponents mean repeated multiplication. It should be 28×28, which works out to be 784." Do you agree with either of them? Explain your reasoning.

Answers

Both Andrew and Elena are wrong. The actual value of 2^28 equals 268,435,456.

Step-by-step explanation:

Elena was right when she said exponents mean repeated multiplication but she accidentally calculated the value of 28^2 instead of 2^28. 2^28 means that the number 2 should be multiplied with itself for 28 times.

2^2 means 2 multiplied by 2 equals 4. 2^3 means 2 multiplied by 2 and then multiplied by 2 again which equals 8. Similarly, if you multiply 2 with itself 28 times you will get a value of 268,435,456 (two hundred and sixty-eight million, four hundred and thirty-five thousand, four hundred and fifty-six). So Andrew and Elena will have 268,435,456 coins after 28 days.

book?​

Answers

The profit on each book is $ 5.25

Solution:

Given that, the drama club at school sells $ 15.00  coupon books

Their profit is 35% of the  total sales

Therefore,

Cost of a coupon book = $ 15

Profit = 35% of the  total sales

We have to find the profit on each book

If a book is sold for $ 15 and then profit will be 35 % of 15

Let us find 35 % of 15

[tex]Profit\ on\ each\ book = 35 \% \times 15\\\\Profit\ on\ each\ book = \frac{35}{100} \times 15\\\\Profit\ on\ each\ book = 0.35 \times 15\\\\Profit\ on\ each\ book = 5.25[/tex]

Thus profit on each book is $ 5.25
