Answer:

Circumference is the distance around a circle, or the perimeter. Area is the space inside the circle. Area has square units, circumference does not. They both have π in the formula.

Circumference is normally used for circles and is asking for the outer edge of the circle while area is the inner part of the shape formulas for circumference is 2 x PIE x radius
While area is length x breadth for most shapes or PIE x (radius)squared so both have to do with measurements and differ in what the measurements are focusing on

Farmer brown has ostriches and llamas. Altogether she counts 98 feet and 33 heads. How many ostriches does she have?

Ronch [10]

Answer: She has 17 ostriches.

Step-by-step explanation:

We know , ostrich has 2 legs where as llama has 4 legs.

Let x be the number of ostriches and y be the number of llamas.

Then, as per given , we have the following linear equations :

$2x+4y=98---(i)\\\\ x+y=33---(ii)$

Multiply 2 to eqn (ii) , we get

$2x+2y=66---(iii)\\$

Subtract (iii) from (i) , we get

$2y=32\\\Rightarrow\ y=16$

Put this in (ii) , we get $x+16=33\Rightarrow\ x=17$

Hence, there are 17 ostriches and 16 llamas.

A music store has sold 3/5 of their hip-hop CDs, but 10 were returned.Now the store has 62 Hip-Hop CDs,How many Hip-Hop CDs did

kow [346]

Answer: 130

Step-by-step explanation:

Let x be the original number of hip- hop CDs in the music store.

Given : A music store has sold 3/5 of their hip-hop CDs, but 10 were returned.

i.e. The number of hip- hop CDs in the store will be :

Original No. of CDs - CDs sold + CDs Returned

$x-\dfrac{3}{5}x+10$

If the store has 62 Hip-Hop CDs now , then required euation will be :-

$x-\dfrac{3}{5}x+10=62$

Subtract 10 from both sides , we get

$x-\dfrac{3}{5}x=52$

$\Rightarrow\ \dfrac{5x-3x}{5}=52$

$\Rightarrow\ \dfrac{2x}{5}=52$

$\Rightarrow\ x=52\times\dfrac{5}{2}=130$

Hence, the number of CDs they originally have = 130
