It is hard to calculate the volume of a mountain but several estimates put the volume of Mount Everest at around 2,413 cubic kil
umka2103 [35]

Answer:

About 609,000 Cowboy stadiums could fit inside of Mount Everest

Step-by-step explanation:

we have

The estimate volume of Mount Everest is at around 2,413\ km^{3}

The Dallas Cowboys Stadium has a volume of 140,000,000\ ft^{3}

step 1

Convert ft³ to km³

we know that

1 km=3,280.84 ft

so

140,000,000\ ft^{3}=140,000,000*(1/3,280.84)^{3}=0.003964\ km^{3}

step 2

To find how many Cowboy stadiums could fit inside of Mount Everest, divide the volume of Mount Everest by the volume of the Dallas Cowboys Stadium

2,413/0.003964=608,729

Round to the nearest Thousands

608,729=609,000

The volume of Mount Everest is about 609,000 times greater than the volume of the Dallas Cowboys Stadium

5x+6y=50<br> -x+6y=26<br> step by step Elimination
slamgirl [31]

Answer:

x=19.998

y=3.333

Step-by-step explanation:

5x+6y=50

-x+6y=26

6y=26+x

x=26-6y

5(26-6y)+6y=50

130-30y+6y=50

130-50=30y-6y

80=24y

y= 3.333

x=26-6y

x=26-(6×3.333)

x=19.998

(2x+ 2) +(3 - 5x) 4.) (3x3 - 4x4) +(2x + 5x4)​
HACTEHA [7]

Answer:

1. \boxed{   \bold{ \sf{ - 3x + 5}}}

2. \boxed{ \bold{ \sf{ {x}^{4}  + 3 {x}^{3}  + 2x}}}

Step-by-step explanation:

1. \sf{(2x + 2) + (3 - 5x)}

When there is a ( + ) in front of expression in parentheses , the expression remains the same.

⇒\sf{2x + 2 + 3 - 5x}

Collect like terms

⇒\sf{ - 3x + 2 + 3}

Add the numbers

⇒\sf{ - 3x + 5}

2. \sf{( {3x}^{3}  - 4 {x}^{4} ) + (2x + 5 {x}^{4}) }

When there is a ( + ) in front of expression in parantheses , the expression remains the same

⇒\sf{3 {x}^{3}  - 4 {x}^{4}  + 2x +  {5x}^{4} }

Collect like terms

⇒\sf{ {x}^{4}  + 3 {x}^{3}  + 2x}

Hope I helped!

Best regards!!
