A triangle has side lengths of (x-6), (x+2) and (x-9). Find the perimeter of the triangle

Answers

Answer:

3x - 13

Step-by-step explanation:

The perimeter is just the distance around the triangle. We have all three sides, so we can just add them together to get the total distance.

(x-6) + (x+2) + (x-9)

Group:

x + x + x - 6 + 2 - 9

3x - 13

The length of each side of an equilateral triangle having an area of 9√3 cm² is

Answers

Answer:

6 cm

Step-by-step explanation:

Let each side of the equilateral triangle be a.

Given, area of an equilateral triangle = 9√3 cm2

Area of an equilateral triangle = (√3)/4 × (Side)²

=> (√3)/4 × a² = 9√3

[tex] {a}^{2} = \frac{9 \sqrt{3} }{ \frac{ \sqrt{3} }{4} } = \frac{9 \sqrt{3} }{ \sqrt{3} } \times 4 = 9 \times 4[/tex]

=> a² = 36

[tex] \sqrt{ {a}^{2} } = \sqrt{36} \\ a = (+ - )6[/tex]

∴ Side = 6 cm  [taking positive square root because side is always positive]

Determine whether the following numbers are rational or irrational​

Answers

Hi! I'm happy to help.

A rational number is a number that repeats, or stops.

First of all, 8/5, in fraction and decimal form (1.6), stops, So it is Rational.

Next, we have pi. This number, doesn't ever stop, or repeat. ( 3.1415926535 897932384626433832795028841971693993751058209749445923078164062862089986280348253421170679...) So, pi, is Irrational.

Next, we have 0. This number stops, so it is Rational.

Next, we have[tex]\sqrt{1}[/tex], the square root of 1, is 1, because 1 squared is one. 1 stops, so it is Rational.

Next, we have 4.46466... This number doesn't stop, and it doesn't seem to repeat, so it is Irrational.

Next, we have -6. -6 stops, so it is Rational.

Finally, we have [tex]\sqrt{2}[/tex]. The square root of 2 is 1.41421356237...

This number doesn't stop, and doesn't repeat, so it is Irrational.

To sum it up: Number 1, 3, 4, and 6 are Rational, and Number 2, 5, and 7 are Irrational.

If y varies inversely as x squaredand y = 6 when x = 30, what is y when x = 6?

Answers

Answer:

150 is write answer

Step-by-step explanation:

mark me a brainlist

Answer:

y = 150

Step-by-step explanation:

Given that y varies inversely as x² then the equation relating them is

y = [tex]\frac{k}{x^2}[/tex] ← k is the constant of variation

To find k use the condition y = 6 when x = 30 , then

6 = [tex]\frac{k}{30^2}[/tex] = [tex]\frac{k}{900}[/tex] ( multiply both sides by 900 )

5400 = k

y = [tex]\frac{5400}{x^2}[/tex] ← equation of variation

When x = 6 , then

y = [tex]\frac{5400}{6^2}[/tex] = [tex]\frac{5400}{36}[/tex] = 150


Find the circumference of a circle that has a diameter of 70 cm.

Answers

Answer:

70 pi cm

219.80 cm

219.9114858 cm

Step-by-step explanation:

The circumference of a circle is given by

C = pi*d

C = pi * 70cm

Using 3.14 for pi

C = 219.80cm

Using the pi button

219.9114858cm

Circumference of circle = 2πr

π = 3.14 r = diameter/2 ; 70/2 = 35

Hence , r is 35 cm

r denotes radius of circle

⇛Circumference of circle = 2πr

⇛Circumference of circle = 2*3.14*35

⇛Circumference of circle = 6.28*35

⇛Circumference of circle = 219.8 cm

Hence , Circumference of circle is 219.8 cm

0.21212121… as a fraction

Answers

It can not be a fraction
Answer:  21/99

Work Shown:

x = 0.212121...

100x = 21.212121....

Subtract the equations straight down. This means we subtract the left hand sides together, and the right hand sides are handled separately.

Left hand sides: 100x-x becomes 99xRight hand sides: 21.212121.... - 0.212121... becomes 21

After those sets of subtractions, we are left with 99x = 21.

This solves to x = 21/99 when dividing both sides by 99 to isolate x.

Therefore, 21/99 = 0.212121...

Amela put 15x- 4 gallons of gas in her car at the beginning of the week. She used 7x-3 gallons driving to work. Which of the following choices represents the
number of gallons left in her car?

A) 22x+7
B) 22x-7
C) 8x+1
D) 8x-1

Answers

Answer:

D) 8x - 1

Step-by-step explanation:

Let's say that x = 5.  That would mean Amelia put 15(5) - 4 gallons of gas in her car, which equals 71 gallons.  She used 7(5) - 3 gallons driving to work, which is 32 gallons used.  71 - 32 = 39 gallons left.

passes through (3,-1), perpendicular to the graph y= -1/3x-4 into slope intercept form

Answers

Answer:

y = 3x - 10

Step-by-step explanation:

The equation of a line in slope- intercept form is

y = mx + c ( m is the slope and c the y- intercept )

y = - [tex]\frac{1}{3}[/tex] x - 4 ← is in slope- intercept form

with slope m = - [tex]\frac{1}{3}[/tex]

Given a line with slope m then the slope of a line perpendicular to it is

[tex]m_{perpendicular}[/tex] = - [tex]\frac{1}{m}[/tex] = - [tex]\frac{1}{-\frac{1}{3} }[/tex] = 3 , then

y = 3x + c ← is the partial equation

To find c substitute (3, - 1 ) into the partial equation

- 1 = 9 + c ⇒ c = - 1 - 9 = - 10

y = 3x - 10 ← equation of perpendicular line

Angle JKL is reffering to the whole angle. The angle is split into two, it gives us the measurement for angle 1 which is 38 degrees. To find the answer we simply subtract angle m from angle JKL. 73-38 = 35... So angle 2 is 35 degrees.

35 , it gave you the amount of JKL. So you do 73-38 and get 35

HELP ME PLS THIS NEEDS TO BE DONE TONIGHT AND TURNED IN TOMORROW The Hamiltons are paving their driveway. They are paving a rectangular area and an area in the shape of a parallelogram to make it easier to turn around and pull out of the driveway. A sketch of the plan for their driveway uses a scale of 1 in. for every 3 ft. What is the actual area of the entire driveway they want to pave? ​

Answers

Answer:

1350 ft²

Step-by-step explanation:

First off, I notice that the triangle at the bottom can fit the slant at the top to make a perfect rectangle.

This will leave us with a rectangle. We can add up 4 and 5 for the sum of 9, making one side 9 inches.

5 + 4 = 9 in

We multiply 9 by 3 to get the actual length of that side

9 x 3 = 27 ft.

We multiply 16 and two-thirds by 3 to get the actual length of the other side

[tex]16\frac{2}{3}[/tex] x 3 = 50 ft.

To find the area of this rectangle we multiply length and width

50 x 27 = 1350 ft²
