Answer:

a) a + c = 29 (1)

10a + 6c = 222 (2)

b) a = 12, c = 17

c) 12 adults and 17 children visited the zoo

Step-by-step explanation:

a)

a + c = 29 (1)

10a + 6c = 222 (2)

b) from (1) a = 29 - c

Plug in (2) 10(29 - c) + 6c = 222

290 - 10c + 6c = 222

-4c = 222 - 290

-4c = -68

c = (-68)/(-4)

c = 17

a = 29 - c

a = 29 - 17

a = 12

c) 12 adults and 17 children visited the zoo

<span>the angle of x ° → 8π </span>


<span>You make the cross-multiply and you can get: </span>

<span>x * π.d = 8π * 360 </span>

<span>x * d = 8 * 360 </span>

<span>x = 8 * 360/d → where d = 2r </span>

<span>x = 8 * 360/2r </span>

<span>x = 4 * 360/r → where r = 4.5 cm </span>

Suppose you like to keep a jar of change on your desk. Currently, the jar contains the following: 2323 Pennies 55 Dimes 2020 Nic
GaryK [48]

Answer:

The answer is "0.081"

Step-by-step explanation:

Dimes = 55

Calculating total coins = (23+55+20+19) = 117

P(for a dime) = \frac{55}{117}

Calculating remaining coins = 116

Nickels = 20

P(for nickel draw in second) = \frac{20}{116}

P(for a dime after that a nickel, without replacement)

= \frac{55}{117} \times \frac{20}{116} \\\\=  \frac{1100}{13572} \\\\=0.081
