Answer:

20km/hr

Step-by-step explanation:

Given that a ship sailed 30km in one and a half hours. We need to find out the rate of ship in kilometres/hour . The rate is also called Speed.

Speed:- Distance travelled per unit time is called Speed .

Here , according to Question,

Distance = 30 km

Time = 1½ hrs .

We know that ,

$\rm\implies Distance = Speed \times Time$

Subsequently ,

$\rm\implies Time = \dfrac{Distance}{Time}$

Substitute the respective values ,

$\rm\implies Rate =\dfrac{ 30km}{ 1.5 hrs }$

We can write 1.5 as 3/2 , therefore ,

$\rm\implies Rate = \dfrac{ 2\times 30}{3} km/hr$

Simplify the RHS ,

$\rm\implies\boxed{\blue{\rm Rate = 20\ km/hr}}$

Hence the Rate/Speed of the ship is 20km/hr .

The width of a rectangle is the sum of the length and 1. The area of the rectangle is 20 units. What is the width, in units, of

IRISSAK [1]

Answer:

W=5

Step-by-step explanation:

W=Width=Length + 1

L = Length

Area = Length * Width = 20

Area = L * W = L * (L+1) = 20

Distribute the L: L^2 + L = 20

Subtract 20 from both sides: L^2 + L -20 = 20-20

Simplify: L^2+L-20=0

Factor (L-4)(L+5)=0

Solve using the zero property: L-4=0, L=4 L+5=0, L=-5

The two options for length are 4 and -5. Only 4 will work for L since it cannot be negative. Width is Length + 1 = 5

PLEASE HELP!!!! WILL MARK BRAINLIEST!!!!

Answer:

None of these.

Step-by-step explanation:

Let's assume we are trying to figure out if (x-6) is a factor. We got the quotient (x^2+6) and the remainder 13 according to the problem. So we know (x-6) is not a factor because the remainder wasn't zero.

Let's assume we are trying to figure out if (x^2+6) is a factor. The quotient is (x-6) and the remainder is 13 according to the problem. So we know (x^2+6) is not a factor because the remainder wasn't zero.

In order for 13 to be a factor of P, all the terms of P must be divisible by 13. That just means you can reduce it to a form that is not a fraction.

If we look at the first term x^3 and we divide it by 13 we get $\frac{x^3}{13}$ we cannot reduce it so it is not a fraction so 13 is not a factor of P

None of these is the right option.

F(x) = (4x–5)/6 Find the Inverse

noname [10]

Answer:

F^-1 (x) = 3x/2+5/4

Step-by-step explanation:

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.

Hope this helps! Stay Safe!
