48% of what number is 108? A. 44.4 B. 51.84 C. 225 D. 5184

Answers

Answer 1
Answer: Let the number = x.

48% of x = 108

(48/100)x = 108

x  =  108 * 100 /48  = 225          use your calculator.

Answer is option C.

Answer 2
Answer: We have an equation: 108/? = 48/100

Cross multiply:
48*?= 108*100
⇒ ?= 108*100/48= 225

The final answer is 225~

Nine tokens are black on one side and white on the other. Initially, four tokens have the black side up (see the picture). In each turn you have to flip three tokens. What is the least number of turns you need to have all tokens showing the same color?

Answers

Answer:

2 Movements

Step-by-step explanation:

Let us name the tokens

B-For Black Tokens

W-For White Tokens

The initial arrangement is therefore given as:

B-B-B-B-W-W-W-W-W

Since we are allowed to flip three tiles in each turn

First movement: Flip two blacks and one white, we would have:

B-B-W-W-W-W-W-W-B

Second movement: Flip the three black tokens, this would give us:

W-W-W-W-W-W-W-W-W

Therefore, the least number of movements to have all tokens showing the same color is 2.

The perimeter of the rectangle is 21.6 m

Further explanation

To solve the above questions, we need to recall some of the formulas as follows:

Area of Square = (Length of Side)²

Perimeter of Square = 4 × (Length of Side)

Area of Rectangle = Length × Width

Perimeter of Rectangle = 2 × ( Length + Width )

Area of Rhombus = ½ × ( Diagonal₁ + Diagonal₂ )

Perimeter of Rhombus = 4 × ( Length of Side )

Area of Kite = ½ × ( Diagonal₁ + Diagonal₂ )

Perimeter of Kite = 2 × ( Length of Side₁ + Length of Side₂ )

Let us now tackle the problem !

Given:

Length of Diagonal = d = 8 m

Angle Between Diagonal and Width = θ = 60°

Unknown:

Perimeter = ?

Solution:

See the picture in the attachment ,

\sin \theta = (BC)/(AC)

\sin 60^o = (BC)/(8)

(1)/(2) √(3) = (BC)/(8)

BC = 8 * (1)/(2) √(3)

BC = 4 √(3)

BC = 4(1.7)

\boxed {BC = 6.8 ~ m}

\cos \theta = (AB)/(AC)

\cos 60^o = (AB)/(8)

(1)/(2) = (AB)/(8)

AB = 8 * (1)/(2)

\boxed {AB = 4 ~ m}

Perimeter ~ = 2 ( AB + BC )

Perimeter ~ = 2 ( 4 + 6.8 )

Perimeter ~ = 2 ( 10.8 )

\large {\boxed {Perimeter ~ = 21.6 ~ m} }

Find x in this right triangle

Answers

Since the triangle is right angled, we may use pythagoras theorem to find the third side.

Pythagoras theorem :-

KI^2 + JI^2 = KJ^2

substituting the known values in the formula,

x^2 + 3^2 = 5^2

x^2 + 9 = 25

x^2 = 25 - 9

x^2 = 16

x = √16

x = 4

Describe how you would rewrite the fractions 1/6 and 1/4 with their least comon denominator.

Answers

1/6 - 6,12,18,24 (we counted by 6's, 2 times to get 12) 
1/4 - 4,8,12,16 (we counted by 4's, 3 times to get 12)

12 is the LCD (Lowest Common Denominator) of the 2 fractions 
 *Now that we have the denominator, we need to find the numerator 

1/12 - 1x2 (why 2? well because we had to count by 6's, 2 times to get 12)
1/4 - 1x3 (why 3? well because we had to count my 4's, 3 times to get 12)

2/12 and 3/12 is the answer 

I hope you get it!!
