Square the radius then divide the radius squared to three times the volume
Ex the radius is 2 the square is 2 4 , and 300 divided by 4 75 for height

What is the value of x in the equation -5/8x=-160?

Helen [10]

Answer:

x= 1/256

Step-by-step explanation:

1. multiply both sides by 8x (answer: -5= 8x*-160)

2. divide both sides by -160 (answer: -5/-160 or 1/32 =8x)

3. divide both sides by 8 (answer: 1/256 = x

4. check your answer: -5/(8*1/256)= -160

Find the least whole number N so that 2020 + N is exactly divisible by 11.

Nadusha1986 [10]

2020 + N ≡ 0 (mod 11)

N ≡ -2020 (mod 11)

Notice that 2020 = 183 • 11 + 7, so

N ≡ -(183 • 11 + 7) (mod 11)

N ≡ -7 (mod 11)

N ≡ 4 (mod 11)

Find dx/dt when y=2 and dy/dt=1, given that x^4=8y^5-240 dx/dt=

katrin2010 [14]

Answer:

The value of $\frac{dx}{dt}$ is $\frac{160}{x^3}$ .

Step-by-step explanation:

The given equation is

$x^4=8y^5-240$

We need to find the value of $\frac{dx}{dt}$ .

Differentiate with respect to t.

$4x^3\frac{dx}{dt}=8(5y^4)\frac{dy}{dt}-0$ $[\because \frac{d}{dx}x^n=nx^{n-1},\frac{d}{dx}C=0]$

$4x^3\frac{dx}{dt}=40y^4\frac{dy}{dt}$

It is given that y=2 and dy/dt=1, substitute these values in the above equation.

$4x^3\frac{dx}{dt}=40(2)^4(1)$

$4x^3\frac{dx}{dt}=40(16)(1)$

$4x^3\frac{dx}{dt}=640$

Divide both sides by 4x³.

$\frac{dx}{dt}=\frac{640}{4x^3}$

$\frac{dx}{dt}=\frac{160}{x^3}$

Therefore the value of $\frac{dx}{dt}$ is $\frac{160}{x^3}$ .
