What is the units digit of 2 to the 50th power
11111nata11111 [884]
Notice that

2^1=2
2^2=4
2^3=8
2^4=16
2^5=32

so that for each power of 2, there is a pattern of period 4. This means that for integers k\ge0, each of 2^{4k}, 2^{4k+1}, 2^{4k+2}, and 2^{4k+3} have the same units digit.

We can write 50=4(12)+2, and since 3=4(0)+2, it follows that 2^{50} and 2^3 share the same units digits. So the units digit of 2^{54} is 8.

Answer:

Width: \frac{3in}{8ft} = \frac{5in}{x} (cross multiply)

   = 40 ÷3 ≈ 13.3ft

Width: \frac {3in}{8ft} = \frac{6.5in}{x}

   = 17.3

A=e × w

   = 13.3 × 17.3 ≈ 230.09 ≈ 230.1

A triangular prism is 40 millimeters long and has a triangular face with a base of 24 millimeters and a height of 35 millimeters
abruzzese [7]

Answer:

26,508

Step-by-step explanation:

To find out how to solve this is that we first need to know that Triangular prisms have their own formula for finding surface area because they have two triangular faces opposite each other. The formula A=12bh is used to find the area of the top and bases triangular faces, where A = area, b = base, and h = height.

Also: To find the total surface area of a prism, you need to calculate the area of two polygonal bases, the top face and bottom face. And then calculate the area of lateral faces connecting the bases. Add up the area of the two bases and the area of the lateral faces to get the total surface area of a prism.

The top= 12 x 24 x 35 = 10,080

The lateral faces: 12 x 37 x 37 = 16,428

Surface Area= 10,080 + 16,428 = 26,508
