What is the value of log256 4

Sauron [17]

Answer: 1/4 or 0.25

Step-by-step explanation: We will solve log256 4 in several steps to solve for x.

Step 1: Log256 4 = x

Step 2: 256x = 4 ( Next, Use exponents )

Step 3: (2^8)x = 2^2

Step 4: 2^8x = 2^2

Step 5: 8x = 2 (Solve for x0

Step 6: 8x/8 = 2/8 = x = 1/4

Step 7 (The Answer) x, or log256 4 = 1/4 or 0.25

There are 9 tennis balls in 3 cans. What is the rate of number of tennis balls to number of cans?

garri49 [273]

ivied the total number of tennis balls buy the number of cans to see how many tennis balls are in 1 can

9 divided by 3 = 3

there are 3 tennis balls per can

fraction would be 3/1 ( meaning 3 balls to 1 can)

12. In the given figure, RS is parallel to PQ, If RS = 3 cm, PQ = 6 cm and ar(∆TRS) = 15cm³, then ar (∆TPQ) = ? (a) 70 cm² (b) 5

Gnesinka [82]

$\large\underline{\sf{Solution-}}$

Given that,

In triangle TPQ, 

RS || PQ,

RS = 3 cm,

PQ = 6 cm,

ar(∆ TRS) = 15 sq. cm

As it is given that, RS || PQ

So, it means

⇛∠TRS = ∠TPQ [ Corresponding angles ]

⇛ ∠TSR = ∠TPQ [ Corresponding angles ]

$\rm\implies \: \triangle TPQ \: \sim \: \triangle TRS \: \: \: \: \: \: \{AA \}$

Now, We know 

Area Ratio Theorem,

This theorem states that :- The ratio of the area of two similar triangles is equal to the ratio of the squares of corresponding sides.

$\rm\implies \:\dfrac{ar( \triangle \: TPQ)}{ar( \triangle \: TRS)} = \dfrac{ {PQ}^{2} }{ {RS}^{2} }$

$\rm\implies \:\dfrac{ar( \triangle \: TPQ)}{15} = \dfrac{ {6}^{2} }{ {3}^{2} }$

$\rm\implies \:\dfrac{ar( \triangle \: TPQ)}{15} = \dfrac{36 }{9}$

$\rm\implies \:\dfrac{ar( \triangle \: TPQ)}{15} = 4$

$\rm\implies \:ar( \triangle \: TPQ) = 60 \: {cm}^{2}$

Answer:

Solution :

********************************************

Two angles are said to be a pair of

adjacent angles if they have a common

arm and lie on the either sides of the

common arm .
