The probability of rolling a six on one die is 1/6. I believe that to get the probability of three dice all landing on a six you have to multiply 1/6 to the third power, giving you 1/216 as your answer.
This scenario sets up a pair of similar right triangles. the smaller triangle had height 5 and base 6,5. the larger had height x (height of the tower, which we want to measure). and base of 177 the proportion is then x/177 = 5/6.5, or
6.5x = 5*177
6.5x=885
x=136.15
answer is 136 feet
Answer:
dA(r) = 6.9 cm²
Step-by-step explanation:
Area of a rectangle is
A(r) = L * W (1)
Where L stands for length and W for width.
Taking differentials on both sides f equation (1)
dA(r) = W*dL + L*dW
As error in measurments are at most 0,1 cm ( in each side), then the maximum error in calculating the area is
dA(r) = 24* ( 0,1) (cm²) + 45*(0,1)(cm²) ⇒ dA(r) = 2.4 + 4.5 (cm²)
dA(r) = 6.9 cm²
Answer:
area of trapezium: 740 cm²
Step-by-step explanation:
![\sf {Area \ of \ trapezium = \frac{1}{2}* (base \ 1 \ + base \ 2) \ * height }](https://tex.z-dn.net/?f=%5Csf%20%7BArea%20%5C%20of%20%5C%20trapezium%20%3D%20%5Cfrac%7B1%7D%7B2%7D%2A%20%28base%20%5C%201%20%20%20%5C%20%2B%20base%20%5C%202%29%20%5C%20%2A%20height%20%7D)
Given here:
- base 1: 34 cm
- base 2: 40 cm
- height: 20 cm
using the formula:
![\sf {Area \ of \ trapezium = \frac{1}{2}* (base \ 1 \ + base \ 2) \ * height }](https://tex.z-dn.net/?f=%5Csf%20%7BArea%20%5C%20of%20%5C%20trapezium%20%3D%20%5Cfrac%7B1%7D%7B2%7D%2A%20%28base%20%5C%201%20%20%20%5C%20%2B%20base%20%5C%202%29%20%5C%20%2A%20height%20%7D)
solve:
![\sf {\frac{1}{2}* (34 \ + 40) \ * 20}](https://tex.z-dn.net/?f=%5Csf%20%7B%5Cfrac%7B1%7D%7B2%7D%2A%20%2834%20%20%20%5C%20%2B%2040%29%20%5C%20%2A%2020%7D)
![\sf {\frac{1}{2}* (74) \ * 20}](https://tex.z-dn.net/?f=%5Csf%20%7B%5Cfrac%7B1%7D%7B2%7D%2A%20%2874%29%20%5C%20%2A%2020%7D)
![\sf 74 * 10](https://tex.z-dn.net/?f=%5Csf%2074%20%2A%2010)
