Equilateral Triangle Three equal angles, always 60

all sides are of equal length (equilateral), and all  angles are right angles. 

A triangle that has no equal sides and no equal angles is known as a Scalene Triangle

while 

if two sides of a triangle are of equal length, then it is called. Isosceles triangle

Explanation

Given:  

- Pages read = 24  

- Time = 15 minutes  

Rate = Pages ÷ Time = 24 ÷ 15 = 1.6 pages per minute

Explanation

The square root of -25 is 5i, where i is the imaginary unit (√-1). 

Since the square root of a negative number is not a real number, we use imaginary numbers to express it.  

So, √(-25) = 5i.

Explanation

A cube can be made with equal blocks for length breadth and height.

Let's see, 1*1*1=1 2*2*2=8 3*3*3=27 4*4*4=64.

Oops, larger than 59. So we need only 27 blocks.

That means that we can take away 50-27=23 blocks.

Explanation

The given series is a square of natural number

(1)^2 = 1

(2)^2 = 4

(3)^2 =9

(4)^2 = 16

(5)^2 = 25

(6)^2 = 36

(7)^2 = 42

(8)^2 = 64

Explanation

To convert the binary number $11000111$to decimal:

1. Write down the binary number: $11000111$
   
2. Identify each bit's position from right to left: $2^0,2^1,2^2,2^3,2^4,2^5,2^6$
3. Assign the binary digits to their respective positions: $1<font\; color="\#0000ff">,</font>\mathrm{<font\; color="\#0000ff">1</font>}<font\; color="\#0000ff">,</font>\mathrm{<font\; color="\#0000ff">0</font>}<font\; color="\#0000ff">,</font>\mathrm{<font\; color="\#0000ff">0</font>}<font\; color="\#0000ff">,</font>\mathrm{<font\; color="\#0000ff">0</font>}<font\; color="\#0000ff">,</font>\mathrm{<font\; color="\#0000ff">1</font>}<font\; color="\#0000ff">,</font>\mathrm{<font\; color="\#0000ff">1</font>}$
   

Now, calculate the decimal value:

$1\times 2^6+1\times 2^5+0\times 2^4+0\times 2^3+0\times 2^2+1\times 2^1+1\times 2^0$

$=64+32+0+0+0+2+1$

$=99$

So, the decimal value of $11000111$ is $99$

Therefore, the correct answer for the MCQ would be: $$99.
