A square pyramid has a base edge of 2 inches and a slant height of 5 in. Find it’s volume
Triss [41]
Volume of the pyramid is V =  (Bh)/3  where B is the base area of the pyramid and h is the height to the pyramid.

B = 2(2) = 4in²
To find h, we need to use the Pythagorean theorem.  The height of the pyramid is actually an altitude that drops straight down from the vertex of the pyramid perpendicular to the Base hitting the Base in the center.  Therefore, the distance from where the altitude hits the Base and the edge of the Base is equal to 1. We are given the slant height as 5 inches so we can now use the theorem to find the height of the pyramid.
h² + 1² = 5²
h² = 5² - 1²
h² = 25 - 1
h² = 24
h =  \sqrt{24}
h=2 \sqrt{6}
Now we can find the Volume:
V= (Bh)/3
V= \frac{[4(2 \sqrt{6} )]}{3} 
V =  \frac{8}{3} \sqrt{6}
This is about 6.5 in³ of volume

Umnica [9.8K]

Answer: the percent of study group students from outside the state is 13%

Step-by-step explanation:

The total number of students in the young woman's study group that are from the town where the young woman's school is located is 7%

The total number of students in the young woman's study group that are from in-state (but not from the school's town) is 80%.

Since the rest are from outside the state, the percent of study group students from outside the state would be

100 - (80 + 7) = 100 - 87 = 13%

Ierofanga [76]

Answer:

P(Yellow) = \frac{29}{147}

Step-by-step explanation:

Given

Brown = 27\\Purple = 47\\Yellow = 29\\Green = 44

Required

P(Yellow) --- next roll to be yellow

This is calculated as:

P(Yellow) = \frac{Yellow}{Total}

So, we have:

P(Yellow) = \frac{29}{27 + 47 + 29 + 44}

P(Yellow) = \frac{29}{147}
