A triangular pyramid has a volume of 333 and one-third yards cubed. What are the possible measures of the area of the base, B, a
FrozenT [24]

To find the option that satisfies the volume of the triangle, we can solve each option.

Formula for the volume a triangular prism: V = 1/3bh

Option A:

B = 50 centimeters squared; h = 10 centimeters

V = 1/3(50)(10)

V = 1/3(500)

V = 166.666... or 166 2/3 yards.

Therefore, this option is incorrect.

Option B:

B = 50 centimeters squared; h = 30 centimeters

V = 1/3(50)(30)

V = 1/3(1500)

V = 500 yards.

Therefore, this option is incorrect.

Option C:

B = 100 centimeters squared; h = 10 centimeters

V = 1/3(100)(10)

V = 1/3(1000)

V = 333.333... or 333 1/3 yards.

Therefore, this option is correct.

Option D:

B = 100 centimeters squared; h = 30 centimeters

V = 1/3(100)(30)

V = 1/3(3000)

V = 1000 yards.

Therefore, this option is incorrect.

Hence, the correct answer is [ B = 100 centimeters squared; h = 10 centimeters ]

Best of Luck!

Why do airplanes look like they are going slower when they are higher in the sky?
dlinn [17]
Our brains judge the speed of objects passing by us through the time taken for them to cross our field of view. Those taking a long time could either be nearby and travelling slowly or faster and further away. And in the case of planes, our brains know that the second interpretation is the right one.

X+y-5z=24,y+z=1,z=-4​
aev [14]

Answer:

x=39, y = 5 and z = -4.

Step-by-step explanation:

x + y - 5z = 24

y + z = 1

z = -4

Plug z = -4 into the second equation:

y + -4 = 1

y = 5.

Now plug x = -4 and y = 5 into the first equation:

x + 5 - 5*4 = 24

x = 24 - 5 + 20

x = 39.
