Pi = 3.142...
1/4 = 0.25
Root 3 = 1.732...
So smallest to biggest: 1/4, root 3, Pi
pie is equal to 3.14, 1/4 is equal to .25, and the square root of 3 is 1.7321

so from least to greatest it would be ordered,

1/4, square root of 3, and pie.

find the surface area

Answers

Answer:

Surface area = 207 cm²

Step-by-step explanation:

Surface are of triangular prism = 2×BA + P × H

Base Area (BA) = ½*bh

b = 8 cm

h = 9 cm

BA = ½*8*9 = 36 cm²

Perimeter of triangular base (P) = 8 + 9 + 10 = 27 cm

Height for prism (H) = 5 cm

Surface area = 2 × 36 + 27 × 5 = 72 + 135

Surface area = 207 cm²

The first platform of the Eiffel Tower is 2,280 inches above the ground. The second platform is 376 feet above the ground. How many yards separate the first platform from the second platform?​

Answers

Answer:

62.0496 yards separate the first platform from the second platform

Step-by-step explanation:

We have to make the conversion of both units to yards.

Each feet has 12 inches.

Each inch is 0.0278 yards.

The first platform of the Eiffel Tower is 2,280 inches above the ground.

So

2280*0.0278 = 63.384 yards above the ground.

The second platform is 376 feet above the ground.

So

376*12*0.0278 = 125.4336 yards above the ground

How many yards separate the first platform from the second platform?​

125.4336 - 63.384 = 62.0496

62.0496 yards separate the first platform from the second platform

Using either substitution or elimination method, solve the system of equations that consists of 8x+y= -16 and -3x+y=-5 Your solution will be a coordinate of integers. ​

Answers

Answer:

x= -1

y= -8

Step-by-step explanation:

Solve for y in 8x + y = -16

y = -16 - 8x

Substitute y = -16 - 8x into -3x + y = -5

-11x - 16 = -5

Solve for x in -11x - 16 = -5

x = -1

Substitute x = -1 into y = -16 - 8x

y = -8

Therefore,

x= -1

y= -8

Answer:

(-1, -8)

Step-by-step explanation:

SUBSTITUTION METHOD:

8x + y = -16-3x + y = -5

Solve for y in the first equation by subtracting 8x from both sides.

y = -16 - 8x

Substitute this value for y into the second equation.

-3x + (-16 - 8x) = -5

Remove the parentheses and simplify.

-3x - 16 - 8x = -5

Combine like terms.

-11x - 16 = -5

Add 16 both sides of the equation.

-11x = 11

Divide both sides of the equation by -11.

x = -1

Substitute this value for x into either equation (I'm using the first equation).

8(-1) + y = -16

Multiply and simplify.

-8 + y = -16

Add 8 to both sides of the equation.

y = -8

ELIMINATION METHOD:

8x + y = -16-3x + y = -5  

Subtract the second equation from the first equation to "cancel" the y-variable.

11x = -11

Divide both sides of the equation by 11.

x = -1

Substitute this value for x into either equation (I'm using the second equation).

-3(-1) + y = -5

Multiply and simplify.

3 + y = -5

Subtract 3 from both sides of the equation.

y = -8

The solution to this system of equations is (-1, -8).
