A perfect square is the product when a number is multiplied to itself. Hence,the square of (3x4) is (3 x 4 x 3 x 4). We can rearrange this and have (3 x 3) x (4 x 4) which gives you 9 x 16. We now have the perfect square of (3x4) re-written as (9 x 16). Thus, the answer is: 9 x 16.

The area of a circle is 80.86cm2.<br> Find the length of the radius rounded to 2 DP.

weeeeeb [17]

Answer:

Solution given:

The area of a circle =80.86cm²

we have:

The area of a circle =πr²

substituting value of area of circle we get

80.86cm=3.14*r²

dividing both side by 3.14

80.86/3.14=3.14*r²/3.14

25.75=r²

doing square root on both side

$\sqrt{25.75}=\sqrt{r²}$

r=5.07cm

Renaldo will write 3/20 as a decimal. Which of the following methods should he use?

makvit [3.9K]

ANSWER

1. Multiply the fraction by 5/5 to get a denominator of 100 and then write the numerator as hundredths using a decimal point.

EXPLANATION

Renaldo wants to write

$\frac{3}{20}$

as a decimal.

He needs a denominator of 100, so he can multiply by

$\frac{5}{5}$

to obtain:

$\frac{3}{20} = \frac{3 \times 5}{20 \times 5}$

This will be

$= \frac{15}{100}$

He can now obtain the decimal equivalent as

$= 0.15$

The correct choice is option 1.

Devide 60 in the ratio of 2:3

nevsk [136]

Answer:

Let the amounts be 2x and 3x.

Then 2x+3x=60

So, 5x=60

So, x=60/5=12

So, amounts are

2x=2*12=24

And 3x=3*12=36

Hope this helps you!
