Answer: <em>1233.02</em>

Step-by-step explanation:

<em>4% = 0.04</em>

<em>1235 × 0.04 = 49.4 (the original number was increased by this amount)</em>

<em>1235 + 49.4 = 1284.4 (new number after increment)</em>

<em>1 284.4 × 0,04 = 51.376 (the number has been reduced by this amount)</em>

<em>1284.4 - 51.376 =  1233.024- final amount.</em>

<em>Rounded to 2 DP: 1233.02</em>

Answer:

1233.02 to 2 D.P.

Step-by-step explanation:

4 % = 0.04

So to obtain the amount after increase by 4% we multiply by 1.04:

1235 * 1.04 = 1284.4

Decreasing by 4%:  we mutriply by 1 - 0.04 = 0.96:

1284.4 * 0.96

= 1233.024.

Anon25 [30]

Add 8 to both sides

12x = 40 + 8

Simplify 40 + 8 to 48

12x = 48

Divide both sides by 12

x = 48/12

Simplify 48/12 to 4

<em>x = 4</em>

Help please, i really need it because its almost due
nata0808 [166]

Answer:

D sqrt( A ) sqrt(pi) / pi = r

Step-by-step explanation:

The area of a circle is given by

A = pi r^2

To find r

Divide each side of the equation by pi

A / pi = pi r^2 /pi

A / pi =  r^2

Take the square root of each side

sqrt(A / pi )= sqrt( r^2)

sqrt(A / pi )= r

We do not like leaving square roots in the denominator, so multiply by sqrt(pi)/sqrt(pi))

sqrt(A / pi ) *sqrt(pi)/sqrt(pi))

sqrt( A ) sqrt(pi) / pi = r
