Find the missing side of each right triangle (((((Pythagorean’s Theorem))))))))

Answer:

A

Step-by-step explanation:

Equation

2x + 3x + 8 + 7x - 2 = 90        

Solution

Combine like terms on the left

12x + 6 = 90                    Subtract 6 on both sides

12x = 90 - 6

12x = 84                         Divide by 12

x = 84/12

x = 7

9514 1404 393

Answer:

  4

Step-by-step explanation:

If the unknown leg is represented by x, then the Pythagorean theorem tells you ...

  x² + 3² = 5²

The sum of the squares of the legs equals the square of the hypotenuse.

Solving for x, we have ...

  x² = 5² -3² = 25 -9 = 16

  x = √16 = 4 . . . . . . . only the positive root is of interest

The missing leg length is 4 units.

Additional comment

This exercise shows you that the triple (3, 4, 5) will form a right triangle. It is the smallest integer "Pythagorean triple", and the only one that is an arithmetic sequence (the differences between the numbers are the same). You will see this a lot, sometimes multiplied by various factors: 6, 8, 10, for example. It is worth remembering.

Answer:

4

Step-by-step explanation:

Correct answers:

$4$

Let a represent the length of the leg and label a on the figure.

The figure shows a right triangle with legs marked a and 3. The hypotenuse is marked 5.

The figure shows a right triangle with legs marked a and 3. The hypotenuse is marked 5.

Using the Pythagorean Theorem with b=3, c=5, and solving for a, we have

a2+b2a2a2a2a2aa=c2=c2−b2=52−32=25−9=16=16−−√=4

The length of the leg is 4.

The steps to take to make sure he bought enough fence are

The perimeter of the rectangular fence is 42 feets.

Therefore, two sides of the garden are 12 feet each long. The other two sides are 108 inches long.

The steps to take to make sure he bought enough fence is as follows:

Therefore,

108 inches = 9 ft

Therefore,

12 + 12 + 9 + 9 = 42 feet's.

He bought 40 feet fence. Therefore, he needs 42 feet's of fence which means the fencing will not be enough.

Answer:

Step-by-step explanation:

if it is  [tex]6^{2}x+ 2.6^{3}[/tex]x = 1  

36x+17.576x = 1

53.576x = 1

x = 1 / 53.576

x = 1 /  [tex]\frac{6697}{125}[/tex]

x = [tex]\frac{125}{6697}[/tex]

or is it

6[tex]x^{2}[/tex] + 2.6[tex]x^{3}[/tex]=1      ?

Answer:

This is what I got.

Step-by-step explanation:

Answer and Step-by-step explanation:

First step we can do is find the slope of the line.

To find the slope, use the following equation:

[tex]\frac{y_2 - y_1}{x_2 - x_1}[/tex]

(2, 0) will be the ([tex]x_{2}, y_{2}[/tex]) set, and (0, 4) will be the ([tex]x_2, x_1[/tex]) set.

[tex]\frac{0 - 4}{2 - 0} = \frac{-4}{2} = -2[/tex]

The slope of the line is -2.

Don't worry about the inequality part yet, make it look like an equation because you'll be more familiar with it.

y = -2x + b (b is the y-intercept)

The y-intercept is the point where the lines intersects with the y-axis. this y-value is 4.

y = -2x + 4 -- That is the equation of the line.

We see that all values make the inequality true is on the left side of this line. This means that the sign to replace the = sign with is >=, in which the values of y are less than what is plugged in and evaluated for x.

y <= -2x + 4

That is the inequality equation.

Answer:

58°

Step-by-step explanation:

A flat angle equals 180°, so we can simply subtract the given angle from the total, 180.

180 - 122 = 58

So, ∠CDE = 58°.

Good luck n.n

Answer:

58°

Step-by-step explanation:

∠AEC =∠AED+∠CED

So,

∠AEC=180°

∠AED=122°

∠CED=?

∠AEC =∠AED+∠CED

180°=122°+∠CED

∠CED=180°-122°

∠CED=58°

No, because the inequality symbol should be less than or equal to 650

If there are already 3 fish in the aquarium. Then the number of fish in the aquarium should be less than 2.

Inequality is simply a type of equation that does not have an equal sign in it. Inequality is defined as a statement about the relative size as well as is used to compare two statements.

There must be fewer than 5 fish in the small aquarium. There are already 3 fish in the aquarium. Then the inequality equation will be

Let the number of fish in the aquarium be x. Then the inequality equation will be

x < 5

But there are already 3 fish in the aquarium, then we have

x - 3 < 2

Then the number of fish in the aquarium should be less than 2.

c) ≈ 6 cars

Step-by-step explanation:

Rate at which cars arrive = 12 cars/hour = 1/5 cars/minute

time needed by each car to complete ATM transaction = 6 minutes = 1/6 car/minute

capacity of lane = 10 car

n = 10

a) Calculate the probability of an arriving not using the ATM because the line is full

p ( not using the ATM ) = 0.19

b) probability that a car will not be able to use the ATM machine immediately on arrival

P ( n > 0 ) = 1 - Po

The ratio of diameters of the two planets has volumes of 8 cubic inches and 27 cubic will be 2/3.

A ratio is defined as a relationship between two quantities, it is expressed as one divided by the other such that they should not be divisible.

The upper number is called as the numerator and the lower is called the denominator.

For example, 3/4 where 3 will be numerator and 4 will be denominator.

Given that the In a display at a museum, two planets have volumes of 8 cubic inches and 27 cubic.

Now volume of planets(sphere) = πD³/6 where D is diameter of sphere

So volume of first planet / volume of second planet ∝ (dia or first)³/(dia of second)³

⇒ V₁/V₂  ∝ (D₁/D₂)³

Given that V₁/V₂ = 8/27

So 8/27 =  (D₁/D₂)³

D₁/D₂ = 2/3

Hence, the ratio of diameters of two planets will be 2/3.
