Explanation

Perimeter of Rhombus  = 2 (l +b)

                                         = 2 ( 6 +6 )

                                         = 2 (12)

                                         = 24

Explanation

The square of a number is the result of multiplying the number by itself.

In this case, 35 squared (written as 35²) is equal to 35 × 35 = 1225.

Explanation

Square (regular quadrilateral):

all four sides are of equal length (equilateral), and all four 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

Kilometres ran by Ali = 4.25 km

In the question,

The length of the jogging track = 1/4 km = 0.25 km

The number of times Ali covered the track = 17

So,

Total distance covered by the Ali is given by,

Total distance = (Number of times he covered the track) x (Length of the track)

So,

The distance in kilometres covered by Ali is,

Distance = 0.25 x 17 = 4.25 km

Therefore, the distance covered by Ali is 4.25 km.

Explanation

When rounding off to the nearest 1000, look at the hundreds place (400 in this case).

Since it's less than 500, you round down to 5000.

Explanation

2/?     =     ?/50

2/10   =    10/50

1/5     =    1/5

The answer is equal by putting value 10.

Explanation

You can easily calculate 18 is 75 percent of what number by using any regular calculator, simply enter 18 × 100 ÷ 75 and you will get your answer which is 24.

Explanation

4404 is divisible by both 3 and 4, making it divisible by 12.

Explanation

A zoo has some lions and Parrots.

A zoo has x lions and y parrots

 The supervisor counted 15 heads and 50 legs. How many lions are there?

Heads

x + y = 15 

y = 15 – x

x = 4 legs and y has 2 legs

4x + 2y = 50

4x + 2(15-x) = 50

4x + 30 – 2x = 50

2x = 20

X = 20/2

X = 10

So x means lions, so there 10 Lions

CHECKING our answer***

  40 + 10 = 50 legs

Explanation

total students = 25

failed = 4

passed students = 25-4 = 21

percentage of pass = 25 is (100%)

failed percentage = 25÷4 = 6.2 %

passed percentage is = 21/25 × 100 = 84%
