How to do the Pythagorean Theorem

KNOW: the height of the triangle is 5 cm and the slope of the triangle is 13

searching for: base of triangle , X

Answer:

X² = a² - b²

X² = 13² - 5²

X² = 169 - 25

X = 144

X. =√144

X =12

that's how to find the result of the Pythagorean Theorem

Step-by-step explanation:

x²=-9-27

x²=-36

there's no x

Answer:

x = ± 6i

Step-by-step explanation:

Given

x² + 27 = - 9 ( subtract 27 from both sides )

x² = - 36 ( negative value indicates the solutions are complex )

Take the square root of both sides

x = ± [tex]\sqrt{-36}[/tex] = ± 6i

30% is the answer........

Answer:

Option C 30%

Step-by-step explanation:

let x%of 50 is 15

X/100×50=15

50x/100=15

X/2=15

X=30

So option C. (30%) is correct

Answer:

b)15.75 and 2.9432

Step-by-step explanation:

The computation of the mean and the standard deviation is shown below:

The mean of a binomial distribution is:

[tex]\mu[/tex] = np

And the standard deviation is

[tex]\sigma[/tex] =  √(npq)

where,

n = 35,

p = 0.45,

and q = 1 - 045 =  0.55

Now mean is

= 35 × 0.45

= 15.75

And, the standard deviation is  

= √(35 × 0.45 × 0.55)

= 2.9432

Hence, the correct option is B.

Answer:

Calculate Percentage Decrease:

First, work out the difference (decrease) between the two numbers you are comparing. Next, divide the decrease by the original number and multiply the answer by 100.

Step-by-step explanation:

The percentage change is equivalent to a 8% decrease followed by a 15% decrease is 78.2%.

To determine the quantity or percentage of something in terms of 100, use the percentage formula. Per cent simply means one in a hundred. Using the percentage formula, a number between 0 and 1 can be expressed. A number that is expressed as a fraction of 100 is what it is. It is mostly used to compare and determine ratios and is represented by the symbol %.

Given:

We have to find percentage change is equivalent to a 8% decrease followed by a 15% decrease.

So, (1- 8%)(1- 15%)

= (1- 8/100)(1-15/100)

= (1-0.8)(1-0.15)

= 0.92 x 0.85

= 0.782

Now, converting to percentage

= 0.782 x 100/100

= 78.2 /100

= 78.2%

Step-by-step explanation: when you round to the tenth place, you look at the number to the right of the decimal. Because it is .95, you round up. If it was .94 or under, you would round down. .95 rounded up would make 10 in the tenths place, so we add our decimal to get 1.0, or 1 inch

Answer:

Total area of board = 36x² + 324 + 216x

Step-by-step explanation:

Given:

Side of square = x + 3

Total number of square = 6 x 6 = 36

Area of each square = Side x Side

Area of each square = (x + 3)²

Area of each square = x² + 9 + 6x

Total area of board = 36[Area of each square]

Total area of board = 36[x² + 9 + 6x]

Total area of board = 36x² + 324 + 216x

Answer:

The time it will take Natalie to pick the forty bushels alone is 10 hours

Step-by-step explanation:

The time it takes Kali to pick forty bushels of apples alone = 15 hours

The time it takes Kali and Natalie to pick forty bushels = 6 hours

The rate at which Kali picks bushels = 40/15 bushels per hour  = 8/3 bushels per hour  

Let x represents the rate at which Natalie picks bushels, we have;

8/3 × 6 + x × 6 = 40

x × 6 = 40 - 8/3 × 6 = 24

x = 24/6 = 4

Therefore;

The rate at which Natalie picks the bushels of apples = 4 bushels/hour

The time it will take Natalie to pick the forty bushels alone = (40 bushels)/(4 bushels/hour) = 10 hours.

Answer:

Slope of 2

Step-by-step explanation:

First thing is to look at the change in x and y from the points. You can do this by subtracting the x valie from the other value and the same for the y values. So you would do 2-0=2.

So we know the change in x between the points, so now we find the change in y. 5-1=4.

Now that we know the change in x and y, we use the expression below to solve for the slope.

[tex] \frac{rise}{run} \: or \: \frac{y}{x} [/tex]

We can insert what we found and then solve for the equation

[tex] \frac{4}{2} [/tex]

So we solve for that, which is 2. Now we know the slope is 2.

Answer:

given us,

(x1y1)= (2,5)

(x2y2)= (0,1)

here,

(y-y1)= (y2-y1)/ (x2-x1)× (x-x1)

or, (y-5)=(1-5)/(0-2)× (x-2)

or, y-5= -4/-2 ×(x-2)

or,y-5= 2(x-2)

or, y-5/ x-2= 2

or,y-5= 2x-4

or, 2x-y= -4+5

:. 2x-y= 1

Step-by-step explanation:

2x-y= 1

Answer:

The diameter is 5ft

Step-by-step explanation:

Given

[tex]Height : Diameter = 21\ in: 17.5\ in[/tex]

Required

Determine the diameter when the height is 6ft

Recall that the scale is a ratio of height to diameter;

So 6ft height can be represented on the following scale model;

[tex]Height : Diameter = 6ft : x[/tex]

Convert to fraction

[tex]\frac{Height}{Diameter} = \frac{6}{x}[/tex] ---- (1)

Recall that:

[tex]Height : Diameter = 21\ in: 17.5\ in[/tex]

Convert to fraction

[tex]\frac{Height}{Diameter} = \frac{21 }{17.5}[/tex] ---- (2)

Equate (1) & (2)

[tex]\frac{6}{x}= \frac{21 }{17.5}[/tex]

Cross Multiply

[tex]21 * x = 6 * 17.5[/tex]

[tex]21x = 105[/tex]

[tex]x = 105/21[/tex]

[tex]x = 5[/tex]

Hence, the diameter is 5ft
