45g: 1kg in its simplest form

Answer»

SOLUTION

TO DETERMINE

45g : 1kg in its SIMPLEST form

EVALUATION

Here the GIVEN RATIO is 45g : 1kg

Now 1 kg = 1000 gm

Hence the given ratio in simplest form

= 45 : 1000

= 9 : 200

FINAL ANSWER

Hence the required ratio = 9 : 200

6.	Lcm of 460,750 step to step
Answer» Step-by-step explanation: Answer: LCM = 2250 Solution by Prime Factorization List all prime factors for each number. Prime Factorization of 450 is: 2 x 3 x 3 x 5 x 5 => 21 x 32 x 52 Prime Factorization of 750 is: 2 x 3 x 5 x 5 x 5 => 21 x 31 x 53 For each prime factor, find where it occurs most often as a factor and write it that many times in a new list. The new superset list is 2, 3, 3, 5, 5, 5 Multiply these factors together to find the LCM. LCM = 2 x 3 x 3 x 5 x 5 x 5 = 2250 In exponential form: LCM = 21 x 32 x 53 = 2250 LCM = 2250 Therefore, LCM(450, 750) = 2250

6.

Lcm of 460,750 step to step

Answer»

Step-by-step explanation:

Answer:

LCM = 2250

Solution by Prime Factorization

List all prime factors for each number.

Prime Factorization of 450 is:

2 x 3 x 3 x 5 x 5 => 21 x 32 x 52

Prime Factorization of 750 is:

2 x 3 x 5 x 5 x 5 => 21 x 31 x 53

For each prime factor, find where it occurs most often as a factor and write it that many times in a new list.

The new superset list is

2, 3, 3, 5, 5, 5

Multiply these factors together to find the LCM.

LCM = 2 x 3 x 3 x 5 x 5 x 5 = 2250

In exponential form:

LCM = 21 x 32 x 53 = 2250

LCM = 2250

Therefore,

LCM(450, 750) = 2250

Answer»

Correct Question:

suppose $\large\rm { [a,b] \subseteq \mathbb{R}}$ , and LET $\large\rm { \varphi}$ be a CONTINUOUS complex valued FUNCTION on the product space $\large\rm { Ω \times [a,b]}$ assume that for each $\large\rm { t \in [a,b]}$ , the function $\large\rm { z \longrightarrow \varphi (z,t)}$ is analytic on $\large\rm{ Ω}$ define F on Ω by $\large\rm { F(z) = \displaystyle\int_{a}^{b} \varphi (z,t) dt, z \in Ω}$ and F is analytic on Ω and $\large\rm { F'(z) = \displaystyle\int_{a}^{b} \frac{\partial \varphi}{\partial z} (z,t) dt , z \in Ω}$

Proof:

FIX any disk $\large\rm{ D(z_{0} , r)}$ such that $\large\rm { \bar{D} (z_{0}, r) \subseteq Ω}$ . Then for each $\large\rm { z \in D (z_{0} , r)}$ ,

$\large\rm { F(z) = \displaystyle\int_{a}^{b} \varphi (z,t) dt}$

$\small\rm { F'(z) = \frac{1}{2 \pi i} \displaystyle\int_{C(z_{0} , r)} \Bigg [ \displaystyle\int_{a}^{b} \varphi(w,t) dt \Bigg ] \frac{1}{(w-z)^{2}} dw}$

diagonals of a Trapezium ABCD with ab parallel to dc intersect each other at point o if AB equal to 3 CD find the ratio of their area of triangle ABC and triangle COD

Answer»

Answer:

9:1

Step-by-step explanation:

Given,

ABCD is a trapezium with AB∣∣CD .......(1)

And

AB=3CD ......(2)

In the triangles AOB and COD,

∠DOC=∠BOA [vertically opposite angles are equal]

∠CDO=∠ABO [alternate interior angles ]

∠DCO=∠BAO

THUS,

△AOB≈△COD

By the similarity rule, the ratio of the areas of the SIMILAR triangles is the ratio of the square of corresponding sides.

therefore

Area (△AOB): Area (△COD)=AB^2 :CD^2

Area (△AOB):Area (△COD)=(3CD)^2 :CD^2

Area (△AOB):Area (△COD)=9CD^2 :CD^2

Area (△AOB):Area (△COD)=9:1

How do you solve for the inverse of one-to-one function?

Answer»

ANSWER:

FINDING the Inverse of a Function

First, replace f(x) with y . ...

Replace every x with a y and replace every y with an x .

Solve the equation from STEP 2 for y . ...

Replace y with f−1(x) f − 1 ( x ) . ...

Verify your WORK by checking that (f∘f−1)(x)=x ( f ∘ f − 1 ) ( x ) = x and (f−1∘f)(x)=x ( f − 1 ∘ f ) ( x ) = x are both true.

Answer:

12

Step-by-step explanation:

LCM of FRACTIONS is lcm of NUMERATORS/ hcf of denominators

= lcm of numerators = lcm(1,2,3,4)=12

=hcf of denominators = hcf(2,3,4,5) =1

lcm of FRACTION = 12/1=12
