Al saves pennies. He agreed to give 3/7 of his pennies to Bev if she would give 3/7 of what she got from Al to Carl and if Carl
ser-zykov [4K]

Answer:

2744 pennies.

Step-by-step explanation:

Let x represent the number of pennies Al have initially.

We have been given that Al agreed to give 3/7 of his pennies to Bev, so number of pennies Bev will get would be \frac{3}{7}x.

We are also told that Bev gave 3/7 of what she got from Al to Carl, so number of pennies that Carl will get would be \frac{3}{7}x\cdot \frac{3}{7}=\frac{9}{49}x.

Further, Carl gave 3/7 of what he got from Bev to Dani, so number of pennies that Dani will get would be \frac{9}{49}x\cdot \frac{3}{7}=\frac{27}{343}x.

We are also told that Dani received 216 pennies. Now, we will equate 216 to \frac{27}{343}x and solve for x as shown below:

\frac{27x}{343}=216

\frac{27x}{343}*343=216*343

27x=74088

\frac{27x}{27}=\frac{74088}{27}

x=2744

Therefore, Al have 2744 pennies initially.

Answer:

a) 23.5619449 m^2     b) 351.8583772 cm^2      c) 75.39822369 cm^2

Step-by-step explanation:

a):

SA = 2πr^2+2πr

r= 3/2 = 1.5

SA= 2π*1.5^2 + 2π*1.5

SA= 15/2 ∏

SA= 23.5619449 m^2 round it as you want

b): Same steps as "a" but rather than m^2 it is cm^2

the answer will be:

SA= 112π

SA= 351.8583772 cm^2  round it as you want

c): the radius is already given so just place it in place of r

SA= 2π*3^2 + 2π*3

SA= 24π

SA= 75.39822369 cm^2
