Answer:

22/10 or 2 and 1/5

Step-by-step explanation:

To find the perimeter, add all sides together. Since it's a rectangle, the other sides are the same measurement as the ones given. Add 3/10, 3/10, 4/5, and 4/5 together. To do this, find a common denominator. The lowest common denominator is 10 so multiply the 4/5 by 2/2 to get the denominator to be 10. Now, add 3/10, 3/10, 8/10, and 8/10. It adds up to 22/10 but if you don't want an improper fraction, simplify it to 2 and 1/5.

The area (A) of a circle with a radius of r is given by the formula A=3.14r^2 and its diameter (d) is given by d=2r. Arrange the

wariber [46]

Answer:

$D=2\sqrt{\frac{A}{3.14}}$

Step-by-step explanation:

we know that

The area of a circle is

$A=3.14r^{2}$ ----> equation A

The diameter of a circle is

$D=2r$ ----> equation B

Solve for r in the equation A

That means ---> isolate the variable r

Divide by 3.14 both sides

$\frac{A}{3.14}=r^{2}$

take the square root both sides

$\sqrt{\frac{A}{3.14}}=r$

Rewrite

$r=\sqrt{\frac{A}{3.14}}$

Substitute the value of r in the equation B

$D=2\sqrt{\frac{A}{3.14}}$

The variable x and y vary directly. Write an equation that relates x and y. Then find y when x = 12.

EastWind [94]

Answer:

24

Step-by-step explanation:

$y=kx$

at (4, 8): 8 = 4k ⇒ k = 2

So $y=2x$

when $x=12$ , $y=2 \times 12=24$
