2t+5v=37 and 4t+3v=39
Solve the first for t
t=18.5-2.5v and use this t in the second equation...
4(18.5-2.5v)+3v=39
74-10v+3v=39
-7v=-35
v=$5.00 and since t=18.5-2.5v
t=$6.00
So tuna sandwiches cost $6.00 and vegetarian sandwiches cost $5.00.
Answer: Probability that a shopper buys shoes and a book is 0.02.
Step-by-step explanation:
Since we have given that
Event A : Buying a pair of shoes
Event B: Buying a book
Since A and B are independent events.
Probability that a shopper buys shoes i.e.
P(A) = 0.20
Probability that a shopper buys a book i.e.
P(B)=0.10
So, we need to find the probability that a shopper buys shoes and a book is given by

Hence, Probability that a shopper buys shoes and a book is 0.02.

Answer:14.4In^3
Step-by-step explanation:
Diameter=3.8In
radius(r)=3.8 ➗ 2=1.9In
volume of hemisphere=2/3 x π x r^3
Volume=2/3 x 3.14 x(1.9)^3
Volume=2/3x3.14x1.9x1.9x1.9
Volume=(2x3.14x1.9x1.9x1.9) ➗ 3
Volume=43.07452 ➗ 3
Volume=14.4In^3
