Answer:

True :  Amanda spends 15% of her salary on food.

False:  Amanda spends 50% of her salary on savings and car payment and insurance combined.

False:  Amanda spends 10% of her salary on phone and internet.

False: Amanda spends 5% of her salary on clothes.

Step-by-step explanation:

The monthly salary of Amanda =   $1,500

Money Savings  =  $475 , Car payment and Insurance   = $425

Phone and internet  =  $175   , Food  =  $225  , Clothes = $100  Misc. = $100

Now, check each of the given statements:

1) Amanda spends 15% of her salary on food.

Now,15% of $1500  =  \frac{15}{100}  \times 1500 = 225

⇒ 15 % of her salary is $225.

So, the given statement is TRUE.

2) Amanda spends 50% of her salary on savings and car payment and insurance combined.

Now,50% of $1500  =  \frac{50}{100}  \times 1500 = 750

Also, combined amount of savings and car payment insurance

=  $475 + $425 = $900

But 50 % of her salary is $750.

So, the given statement is FALSE.

3)  Amanda spends 10% of her salary on phone and internet.

Now,10% of $1500  =  \frac{10}{100}  \times 1500 = 150

⇒ 10 % of her salary is $150.  But she spends $175 on phone and internet

So, the given statement is FALSE.

4)Amanda spends 5% of her salary on clothes.

Now,5% of $1500  =  \frac{5}{100}  \times 1500 = 75

⇒ 5 % of her salary is $75.  But she spends $100 on her clothes.

So, the given statement is FALSE.

patriot [66]

Answer:

Step-by-step explanation:

If we choose chairs having odd number in the row

no of chairs from which selection is made = 10

no of chairs to be selected = 5

no of ways = 10C₅

similarly if we choose hairs having even numbers only ,

similar to above , no of ways

= 10C₅

Total no of ways

= 2 x 10C₅

= 2 x 10 x 9 x 8 x 7 x 6 / 5 x 4x3 x 2 x 1

= 504 .

Question 1: find the volume of a cube whose total surface area is 486cm^2
lapo4ka [179]
<h3>The volume of cube is 729 cubic centimeter</h3>

<em><u>Solution:</u></em>

<em><u>The surface area of cube is given as:</u></em>

Surface\ area = 6a^2

Where, "a" is the length of side of cube

Given that, surface area = 486 square centimeter

486 = 6a^2\\\\a^2 = \frac{486}{6}\\\\a^2 = 81\\\\a = 9

<u><em>Find the volume of cube:</em></u>

volume\ of\ cube = a^3\\\\volume\ of\ cube = 9^3\\\\volume\ of\ cube = 9 \times 9 \times 9\\\\volume\ of\ cube = 729

Thus volume of cube is 729 cubic centimeter
