What Is The Value Of X In The Nearest Whole Number

Answers

Answer 1

Answer:

16

Step-by-step explanation:

To calculate x we must use the trig function of tangent:

as tangent is opposite divides by adjacent we can get this equation:

[tex]\tan 30 = \frac{9}{x}[/tex] which is equal to:

[tex]x=\frac{9}{\tan 30}[/tex] So x must equal to 15.588.. (just put the second bit in the calculator

As all the values provided are integers you round this to the nearest whole number:

16 (as the third digit, 5, rounds up)

so our answer is 16

Fiona wants to rope off a triangular region in her yard for a vegetable garden. She has 90 feet of rope to use, she wants the distance between each stake to be an integer, and the distance between two of the stakes must be 36 feet.

A. What is the greatest possible distance between any of the stakes?

B. If she wants to create a right triangular region and use all of the 90 feet of rope, what would be the lengths of the sides of the region?

Answers

Answer:

A.) The greatest possible distance between any of the stakes is 53 feet.

B.) A triangle with sides 15, 36, and 39 is a right triangle and has perimeter 90 feet.

Step-by-step explanation:

Given - Fiona wants to rope off a triangular region in her yard for a vegetable garden. She has 90 feet of rope to use, she wants the distance between each stake to be an integer, and the distance between two of the stakes must be 36 feet.

To find - A. What is the greatest possible distance between any of the stakes?

B. If she wants to create a right triangular region and use all of the 90 feet of rope, what would be the lengths of the sides of the region?

Solution -

A.)

Let us assume that,

Length of side 1 = x

Length of side 2 = y

Length of side 3  = z

Now,

Given that,

She has 90 feet of rope to use

⇒x + y + z = 90

And

The distance between two of the stakes must be 36 feet.

So, Let z = 36.  

∴ we get

x + y + 36 = 90

⇒x + y = 90 - 36

⇒x + y = 54

Now,

Let x be as large as possible.

i.e. To make x to be large, y has to be as small as possible.

It happens when y = 1.

( We can not take y = 0, or else a triangle won't form)

∴ we get

y = 1

⇒x + 1 = 54

⇒x = 54 - 1

⇒x = 53

∴ we get

The greatest possible distance between any of the stakes is 53 feet.

B.)

We know that,

(5,12,13) is a Pythagorean triple.

Because 5² + 12² = 13²

So,

As, we have a Pythagorean triple,

This means a triangle with sides 5, 12, 13 is a right triangle.

Now,

If a triangle has sides 5, 12, 13,

⇒ The perimeter becomes 5 + 12 + 13 = 30.

By Triple each side we get,

Length of sides 15, 36, 39.

The perimeter i= 15 + 36 + 39 =  90

Also,

We can see that,

15² + 36² = 39².

This means we have a right triangle and (15, 36, 39) is another Pythagorean triple.

Because any scaled version of a Pythagorean triple, is also a Pythagorean triple.

∴ we get

A triangle with sides 15, 36, and 39 is a right triangle and has perimeter 90 feet.

The circle is open because based on the concept that in inequalities, less/greater than and/or equal to (such as these ≥ ≤ ) signs are graphed with closed circles, while less/greater than (like these > <) signs are graphed with open circles. The direction of the arrow is moving to the left on the number line because all possible values for x would be less than 1. When graphing the inequality you would use a solid line rather than a dashed line (I had to improvise since I could not attach an image).

Which matrix represents the system of equations shown below?
4x - 2y = 8
2x-3y = 12

Answers

Answer:

4x-2y=8

or, 4x = 8+2y

or x = 8+2y/4-----(eq.1)

2x-3y=12-----(eq.2)

Now,

putting value of eq.1 in eq.2, we get

2x-3y=12

or, (8+2y/4)-3y = 12

or, 8-10y/4=12

or, 8-10y=12×4

or,8-10y=48

or,-10y=48-8

or,y=40/-10

or, y = -4

again,

2x-3y=12

or, 2x-3×-4=12

or, 2x+12=12

or, x=0

In 1st option

4x-2y=8

or,4×0-2×-4=8

or,0+8=8

8=8

2x-3y=12

2×0-3×-4=12

0+12=12

12=12

So 1st option is true
