How do you divide 50 by 60 and get 85

you cannot get that answer.... when you divide. Put the number into a fraction first so, it makes it easier to see what you are doing. So, $\frac{50}{60}$ .Now simplify the cross off the zero from the top and the bottom to get $\frac{5}{6}$ . So, $\frac{5}{6}$ will give you 0.83333333333...3.

You cant get the answer... if u divide you eather have even numbers or like for example 5 10 15 20 do u get the patters it is 5 plus 5 plus 5 another method is repeated subtraction

Find the greatest common factor of 6w^3 and 5n^4

scZoUnD [109]

Hi there!

• Greatest Common Factor :-

GCF is th' greatest factor that divides two numbers.

To find the GCF of two numbers :-

→ List the prime factors of each number.
→ Multiply those factors both numbers have in common.

Accr'ding to the question :-

5n⁴ = 5 × n × n × n × n × 1
6w³ = 2 × 3 × w × w × w × 1

Greatest Common Factor [ 5n⁴, 6w³ ] = 1

~ Hope it helps!

Evaluate the line integral ∫cf⋅dr, where f(x,y,z)=5xi−4yj+3zk and c is given by the vector function r(t)=⟨sint,cost,t⟩, 0≤t≤3π/2

Katena32 [7]

WIth the parameterization

$\mathbf r(t)=\langle\sin t,\cos t,t\rangle$

we end up with

$\mathbf f(\mathbf r(t))=\mathbf f(\sin t,\cos t,t)=5\sin t\,\mathbf i-4\cos t\,\mathbf j+3t\,\mathbf k$

We also have

$\mathrm d\mathbf r=\mathbf r'(t)\,\mathrm dt=\langle\cos t,-\sin t,1\rangle\,\mathrm dt$

So in the line integral, we get

$\displaystyle\int_{\mathcal C}\mathbf f\cdot\mathrm d\mathbf r=\int_{t=0}^{t=3\pi/2}\mathbf f(\mathbf r(t))\cdot\mathbf r'(t)\,\mathrm dt$

$=\displaystyle\int_{t=0}^{t=3\pi/2}(9\sin t\cos t+3t)\,\mathrm dt=\frac98(3\pi^2+4)$

The record time for running the Boston Marathon is 2.12 hours at an average speed of 12.5 miles per hour. What distance does the

Gala2k [10]

Answer:

26.5 miles.

Step-by-step explanation:

Given: Time for running Boston Marathon= 2.12 h

Speed= 12.5 mph

Distance covered in Boston Marathon

Distance covered= speed x time

Distance covered = 12.5 x 2.12=26.5 miles

∴ Distance covered in the Boston Marathon is <u>26.5 miles.</u>

Please answer! this is an important exam that im taking right now.

Answer:

Required ordered pair is (0,0) for system of equation

Step-by-step explanation:

The given system of equation is

A). $9^{12x} = 9^{3y}$

B). $y^{4} - 9y^{2} x^{2} =16y$

On simplifying the equation A

$9^{12x} = 9^{3y}$

Take log on both side,

(12x) (log9) = (3y) (log9)

4x=y

To find the solution of the system of the equation :

Replacing value of y=4x in equation B,

$y^{4} - 9y^{2} x^{2} =16y$

$(4x)^{4} - 9(4x)^{2} x^{2} =16(4x)$

$256x^{4} - 144x^{2} x^{2} =64x$

$256x^{4} - 144x^{4}=64x$

$112x^{4}=64x$

We get,

x=0 and x=0.829

Since, 0.829 is not integer number

Only solution of equations is x=0

For the value of y

Replace value x in y=4x=0

Thus, Required ordered pair is (0,0)
