Its already written as a decimal but it can be 8 1/2
Answer:
$0.98
Step-by-step explanation:
Given data
Cost of sinuses apples = $9.8 for 10 pound
We want to find the cost per pound
Hence
if 10 pounds cost $9.8
1 pound will cost x
cross multiply
x= 9.8/10
x= $0.98
Hence a pound will cost $0.98
Answer:5.25
Step-by-step explanation:
(7/8 of a mile) x (6 days)
Answer:
5.6 days
Step-by-step explanation:
We are given;
Initial Mass; N_o = 25 g
Mass at time(t); N_t = 25/2 = 12.5 (I divide by 2 because we are dealing with half life)
k = 0.1229
Formula is given as;
N_t = N_o•e^(-kt)
Plugging in the relevant values;
12.5 = 25 × e^(-0.1229t)
e^(-0.1229t) = 12.5/25
e^(-0.1229t) = 0.5
(-0.1229t) = In 0.5
-0.1229t = -0.6931
t = -0.6931/-0.1229
t = 5.6 days
Answer:
20
Step-by-step explanation:
f = 2f - 20
f - 2f = - 20
- f = - 20
f = 20
