$t=\frac{a}{\sqrt{1-\frac{y^2}{c^2}}}\\\frac{y^2}{c^2}=1-\frac{a^2}{t^2}\\y^2=\frac{c^2t^2-c^2a^2}{t^2}\\y=\frac{c}{t}\sqrt{t^2-a^2}$

$t=\frac{a}{\sqrt{1-\frac{v^2}{y^2}}}\\\frac{v^2}{y^2}=1-\frac{a^2}{t^2}\\\\\frac{v^2}{y^2}=\frac{t^2-a^2}{t^2}\\y^2=\frac{v^2t^2}{t^2-a^2}\\y=\frac{vt}{\sqrt{t^2-a^2}}$

4. rafoxy35 says:

$d=\frac{C}{\pi}$

Step-by-step explanation:

Given : C equals pi multiplied by d

We have to solve the equation for d.

Consider the given C equals pi multiplied by d

We first write it mathematically ,

$C=\pi\times d$

We have to solve for d, that is ,

Divide both side by π, we have,

$\frac{C}{\pi}=d$

Thus, $d=\frac{C}{\pi}$

5. scavalieri2421 says:

D

Step-by-step explanation:

D is the answer because if you look at the question it is saying "C equals pi times d" so, in this case it would be c=pi/d and none of the answers given is showing that, so therefore D is the answer

6. LukeneedhelpInMath says:

d = $\frac{C}{3.14}$

Step-by-step explanation:

Given

C = 3.14d ( isolate d by dividing both sides by 3.14 )

$\frac{C}{3.14}$ = d

Answers are mentioned along with explanations/

Explanation:

1. We are given D = 5R

where D = no. of diamonds and R = no. of rubies

a. In words, Number of diamonds = 5 times no. of rubies

In letters D = 5R

b. Given R = 4, so D = 5 x R = 5x 4

D = 20

c.  Given R = 10 , so D = 5 x R = 5x 10

D = 50

d. Given D = 15 , D = 5R so , R = D/5 = 15/5 = 3

R = 3

e. R = $\frac{D}{5}$  because D = 5R

2. Given A = B + C

a. B = 5 , C = 2 => A= 5+2 => A= 7

b. B = A - C from above equation and given A = 10 , C = 2 , B= 10 - 2

B = 8

c.  two values of B and C for A to be 7

B = 4 C = 3 and vice versa as 4+3 = 7

d. B = A - C by moving C on the RHS thus changing its prefix sign.

3. Given A = 3x and B = 5x+1

a. B goes up faster because it is 5 times x plus 1 where A is just 3 times x

b. if x = 0, A = 3x = 3x0 = > A = 0

c. if x =1 , B = 5x+1 = 5x1 +1 = 5+1 => B = 6

4. Given A = 2x and B = x2 where x2 means x*x so,

a. if x=1 , A = 2*1 = 2 and B = 1*1 = 1

b. if x = 3, A = 3*1 = 3 and B = 3*3 = 9

5. Given D =2R

a. given R = 8 , D = 2*8 => D=16

b. given R =3 then D = 2*3 => D = 6

c. D= 20 given, R = D/2 = 20/2 => R = 10

d. D = 100 so R = D/2 = 100/2 => R =50

e. R = $\frac{D}{2}$ or D/2

6. Given C = π D and π  = 3.14

a. if D = 20, C = 3.14*20 => C = 62.8 centimeters

b. if D = 10, C = 3.14*10 => C = 31.4 inches

c. Given C = 18, D = C/31.4 = 18/3.14 => D = 5.732 inches

7. Given S = D/T

a. S = 12/3 = 4 feet/seconds

b. S = 100/5 = 20 miles/seconds

c. For S = 4feet per second , D = 8 ft and T = 2 seconds as S = D/T

we know that

The formula to calculate the circumference of a circle is equal to

$C=\pi d$

where

d is the diameter of the circle

Solve for d

That means------> isolate the variable d

$C=\pi d$

Divide by $\pi$ both sides

$d=C/\pi$

therefore

$d=C/\pi$
