1. For the carnival, the park rented a dunking booth shaped as a rectangular prism. The booth is 3 1/2 ft wide, 3 1/2 ft long, a

tangare [24]

Answer:

Part a) The total volume is $98\ ft^{3}$

Part b) $84\ ft^{3}$

Step-by-step explanation:

Part a)

Find the total volume

we know that

The volume of a rectangular prism is equal to

$V=LWH$

we have

$L=3\frac{1}{2}\ ft=\frac{3*2+1}{2}=\frac{7}{2}\ ft$

$W=3\frac{1}{2}\ ft=\frac{3*2+1}{2}=\frac{7}{2}\ ft$

$H=8\ ft$

substitute in the formula

$V=(\frac{7}{2})(\frac{7}{2})(8)=98\ ft^{3}$

Part b) If they are only going to fill the dunking booth 6/7 full, how many cubic feet of water will they need?

Multiply the total volume by 6/7

$98(6/7)=84\ ft^{3}$

Answer: 11
step by step instructions: so you have your statement. (3/7)r+(5/8)s you then would plug in (14) for (r) and (8) for (s).once you plug these in you then simplify the statement. (3/7)*14=6 and (5/8)*8=5. so your new statement should be 6+5=11
hope this helps

1/12

there are 6 faces of dice :1,2,3,4,5,6
total no. of faces(N)= 6
to make four it should= (1+2) (2+2) (3+1)
total no of dice(n) = 2
formula=
$N^{n}$
probability= 3/36
=1/12
