Reil [10]

Area of the base = 8^2 = 64

area of 1 traingle = 1/2 * 8 * 5.4 = 21.6

there are 4 triangular sides so their area = 4 * 21.6 = 86.4

Total surface area = 64 + 86.4 = 150.4 cm2

Johnny has a bag with 84 coins in it. If the ratio of dimes to nickels to pennies is 3 to 2 to 1, how many

omeli [17]

Answer:

Step-by-step explanation:

Number of coins in the bag ⇒ 84

Give that,

Dimes : Nickels : Pennies

3 : 2 : 1

You can see that, there are 6 parts . ( 3 + 2 + 1 = 6 )

And now let us write the types of coins in fractions.

Dimes ⇒ $\frac{3}{6}$

Nickels ⇒ $\frac{2}{6}$

Pennies ⇒ $\frac{1}{6}$

And now they're asking for the number of nickels.

To find that, you can multiply 84 ( number of coins) by it's fraction ( 2/6).

Let us solve.

84 × $\frac{2}{6}$

$\frac{84*2}{6}$

$\frac{168}{6}$

Therfore, there are 28 nickels.
