I need help on number 18

zloy xaker [14]

Answer:

Volume = 35185.8 $km^{3}$

Step-by-step explanation:

Recall the formula for the volume of a cone: $Volume = \pi R^{2} \frac{h}{3}$

Where R is the radius of the cone's circular base (in your case half of 80 km,(that is 40 km)

And h stands for the height of the cone (in your case 21 km)

We replace such in the formula and calculate its final value:

$Volume = \pi 40^{2} \frac{21}{3} = \pi 1600 \frac{21}{3} = \pi 1600 (7) = 35185.83772...$

We round it to the number of decimals your problem request (let's say to one decimal) and also include the cubic units:

Volume = 35185.8 $km^{3}$

Solve the solution of the equations 10x-3y=3 and 2x+y=9

forsale [732]

Answer:

x=1.875 y=-0.875

Step-by-step explanation:

10x-3y=3 10x-3y=3

3(2x+y)=(9)3 +6x+3y=27

1/16(16x)=(30)1/16 = x=1.875

10x-3y=3 10x-3y=3

-5(2x+y)=(9)-5 -10x-5y=4

1/-8(-8y)=(7)1/-8 = y=-0.875

True or false? And why? The value of |x +1| is greater than or equal to 0

goldfiish [28.3K]

True.

The absolute value of anything is the distance that value is away from zero.

For instance, |-5 + 1| = 4

As we can see, any number that we plug into this equation will always be a number equal to or greater than zero.
