Where is the blue dot on the number line?
-4.5
-5
-5.5

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]

C.(CCCXLIII)

Step-by-step explanation:

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.  

What else equals 39, you might ask?

8(5) - 1

40 - 1

39.

Answer:

It is C

Step-by-step explanation:

PM = QM

[tex]6x - 8 = 2x + 4 \\ 6x - 2x = 4 + 8 \\ 4x = 12 \\ x = 3[/tex]

Answer:

C.) x = 3

Step-by-step explanation:

The diagonals of a rectangle are equal, and QM and PM are both half of the two diagonals. You can now say that 2 * (6x - 8) = 2 * (2x + 4), meaning that 12x - 16 = 4x + 8, where you can add 16 on both sides, then subtract by 4x on both sides to get that 8x = 24. Now divide by 8 on both sides to get that x = 3.

Answer:

isosceles traingle have two equal side

Integers.

The integers are the whole numbers, their opposites, and 0 . From the given numbers, −7 and 8 are integers. Also, notice that 64 is the square of 8 so −√64=−8 . So the integers are −7,8,−√64 − 7 , 8 , − 64 .

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

C 6 loaves with flour left over

Step-by-step explanation:

Take the amount of flour and divide by the amount of flour per loaf

9/2 ÷ 2/3

Copy dot flip

9/2 * 3/2

27/4

Change to a mixed number

4 goes into 27 6 times with 3 left over

In red : y=x+2(x-[x])

Answer:

x = 125

Step-by-step explanation:

All triangle interior angles add up to 180 so:

x + 25 + 30 = 180

x + 55 = 180

x = 180 - 55

x = 125

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

Answer:

creo que es la respuesta 8× +8=72

Answer:

Answer: Rocket distance (rocket sled) =3 mil Time Taken=6seconds

Average Speed=Total Distance ÷ Time Taken. Average speed= 3÷ 6=1/2. So therefore average speed in miles per seconds= Average in miles/seconds

Average speed in miles per seconds=1/2

Average in miles/hour = Average speed in miles per seconds/hour.

Average in miles/hour=1/2÷60=30

Therefore Average speed in miles per hour =30 miles per hour

x-intercept(s):  

( − 4 , 0 ) , ( 6 , 0 )

y-intercept(s):  

( 0 , − 24 )

Answer:1 and 2

Step-by-step explanation:right on edge

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.

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...

Answer:

112 guests

Step-by-step explanation:

I. If her total cost is 773$

When Total = DJ + Cake + Guest

            773 = 250 + 75 + 4(x)

            773 = 325 + 4(x)

            773 - 325 = 4(x)

            448 = 4x

               x = 448/4

               x = 112

That makes guests are 112
