Answer:

The surface area of a solid object is a measure of the total area. Find the area of all the sides and add them up.

Area of rectangles:

40+40+16+16= 112

split the pentagon so they will be a reactangle and a triangle.

6-2=4. The height of the triangle is 4.

3+3=6, 6*2=12. 12 is the area of the mini rectangles, 12*2=24. 24 is the total area for both the mini rectangles.

Area of the triangle is 12.

Add them all up:

112+12+24= 148

148

Hope this helps!!

Convert the following: 110110two to base ten 25ten to base two

blagie [28]

Answer:

110110 in base 2 when converted in base 10 will be equal to 54
25 in base 10 is equal to 1001 base 2

Step-by-step explanation:

Part 1: 110110two to base ten

For conversion from base 2 to base 10 we multiply each digits of given number with powers of 2

$=1*2^5 + 1 * 2^4 + 0 * 2^3 + 1 *2^2 + 1* 2^1 + 0*2^0\\ =1*32+ 1* 16 + 0 + 1*4 + 1*2 +0\\ =32 + 16 +4 + 2\\ = 54$

So 110110two when converted in base 10 will be equal to 54

Part 2: 25ten to base two

For conversion from base 10 to base 2 we will divide the given number with 2 repeatedly and store the remainders until the quotient comes 1. The solution is as follows:

25/2 = 12 remainder 1

12/2 = 6 remainder 0

6/2 = 3 remainder 0

3/2 = 1 remainder 1

Now the remainders will be written in inverse order as:

=1001 base 2

So 25 in base 10 is equal to 1001 base 2

I hope it will help you!
