What IS 20 divided by 13 ?

Mathematics
2 answers:
diamong [38]3 years ago

<em>20/13</em>

<em>and as you know it can only go into 20 once. </em>

<em>so you can do this 13/13 and 20/13</em>

<em>that leaves 7 of 20 and 13</em>

<em>wait if this is confusing then,</em>

<em>_______________________________________________</em>

<u><em>20/13 - 13/13 = 7/1</em></u>

<em>_______________________________________________</em>

<em>= 1.53</em>

Solution,\mathrm{Convert\:improper\:fractions\:to\:mixed\:numbers}:\quad \frac{20}{13}=1\frac{7}{13}

Steps:

\frac{20}{13}

\mathrm{Long\:Division}\:\frac{20}{13}:\quad 1\quad \mathrm{Remainder}\quad \:7

Convert\:to\:mixed\:number:\:Quotient\frac{Remainder}{Divisor},\\\frac{20}{13}=1\frac{7}{13}

Hope\: This\: Helps!!!

So the formula for the volume of a sphere is 4/3 * (π * r³)

V = 4/3 * (π * 6³)

V = 4/3 * (π * 216)

V = 4/3 * 678.24

V = 904.78

A dog jumps straight up. Y=-16t^2+20t models the motion of the dog, where "t" is the time in seconds and "y" is the height of th
alina1380 [7]

Answer:

Step-by-step explanation:

The motion of the dolphin is quadratic

i.e y=-16t²+20t

To get the maximum height the dolphin will reach

We need to find the point of inflexion. i.e dy/dt=0

dy/dt=-32t+20

Then set dy/dt=0

0=-32t+20

Then, -32t=-20

t=0.625

Let find d²y/dt²

d²y/dt²=-32. Since this is negative then the point t=0.625 is the maximum point the dolphin can reach

Then substitute t=0.625 into y

y=-16t²+20t

y=-16(0.625)²+20(0.625)

y=6.25ft

Then the maximum height the dolphin can reach is 6.25ft

Using discriminant

Formular method

y=-16t²+20t

So the dog height y<7

y=-16t²+20t <7

-16t²+20t-7<0

a=-16, b= 20. c=-7

t=(-b±√b²-4ac)/2a

Using the a, b and c direct for the discriminant

D=b²-4ac

D=20²-4×-16×-7

D=-48

Which is a complex number

Then the dolphin can reach the height

Then we need to model the D to be greater than 0

Therefore,

D>0

b²-4ac>0

We cannot do anything to a and b it is already given

a=-16, b=20

(20)²-4(-16c)>0

400+64c>0

64c>-400

Then

c>-6.25

Divide both side by - and the inequality sign will change

Therefore -c<6.25

So the dog height y<6.25

y=-16t²+20t <6.25

Therefore the maximum height is 6.25.

If it is greater than that then, we are going to have a complex root movement which is not possible for the dolphin .

Solve for y. -3/y=6 Simplify your answer as much as possible.
Molodets [167]
Solving for "y" means that we need to get y to be on one side of the equation. It should look like y= something. To get the y by itself, we need to get rid of that -3. To do that, we'll have to divide by -3 (because even though there's a y being divided, the -3 is still the numerator). 6/-3 is -1/2. Therefore your answer is y=-1/2
