Answer:

9 : 3, 12 : 4, 54 : 18, 18 : 6 and so on

Step-by-step explanation:

Ratios equivalent to 27 : 9

Although, choices are not available to pick from, however, we can still find equivalent ratio to 27 : 9

27 : 9

= 27 / 9

= 3 / 1

= 3 : 1

Equivalent ratio

9 : 3

= 9 / 3

= 3 / 1

= 3 : 1

Another equivalent ratio is

12 : 4

= 12 / 4

= 3 / 1

= 3 : 1

Another equivalent ratio

54 : 18

= 54 / 18

= 3 / 1

= 3 : 1

Another equivalent ratio is

18 : 6

= 18 / 6

= 3 / 1

= 3 : 1

Therefore, equivalent ratio to 27 : 9 includes 9 : 3, 12 : 4, 54 : 18, 18 : 6 and so on

2(x+3)=x-4<br> please help me &lt;3
vovikov84 [41]
2(x + 3) = x - 4

distribute

2x + 6 = x - 4

either subtract 6 from both sides or add 4. i will be subtracting 6.

2x = x - 10

subtract x from both sides

x = -10

I really need help with this please ! I don't understand it, and I have a quiz tomorrow
erik [133]
You can do this by finding a number close to it, and then finding out how to do it.

For example with 63(square root sign), find out what is close to it.

7x7=49 while 8x8=64

Because of this, we now know that it is between 7 and 8 but is also really close to 8.

Our number could be 7.9

Hope this helped!!!

A metal hollow bar whose cross section and dimension are shown below weighs 8x10^3 kg/m^3 and measure 2m in length ..determine t
devlian [24]
1) We calculate the volume of a metal bar (without the hole).

volume=area of hexagon x length
area of hexagon=(3√3 Side²)/2=(3√3(60 cm)²) / 2=9353.07 cm²
9353.07 cm²=9353.07 cm²(1 m² / 10000 cm²)=0.935 m²

Volume=(0.935 m²)(2 m)=1.871 m³

2) we calculate the volume of the parallelepiped

Volume of a parallelepiped= area of the section  x length
area of the section=side²=(40 cm)²=1600 cm²
1600 cm²=(1600 cm²)(1 m² / 10000 cm²=0.16 m²
Volume of a parallelepiped=(0.16 m²)(2 m)=0.32 m³

3) we calculate the volume of a metal hollow bar:
volume of a metal hollow bar=volume of a metal bar -  volume of a parallelepiped

Volume of a metal hollow bar=1.871 m³ - 0.32 m³=1.551 m³

4) we calculate the mass of the metal bar

density=mass/ volume  ⇒ mass=density *volume

Data:
density=8.10³ kg/m³
volume=1.551 m³

mass=(8x10³ Kg/m³ )12. * (1.551 m³)=12.408x10³ Kg

answer: The mas of the metal bar is 12.408x10³ kg  or   12408 kg

A hot air balloon went from an elevation of 6,039 feet to an elevation of 3,288 feet in 42 minutes. What was its rate of descent
Vikki [24]

Answer:

65.5 feet per second

Step-by-step explanation:

In order to calculate the rate of descent we first need to find the difference in heigh that the hot air balloon descended. We do this by subtracting the initial height from the end height like so...

6,039 - 3,288 = 2,751 ft

Now that we have the difference in height we need to divide this by 42 since that is the amount of time it took for this descent to occur.

2,751 ft / 42s = 65.5 ft/s

Finally we can see that the rate of descent was 65.5 feet per second
