there are 60 minutes per hour
99/60 = 1.65 km per minute
1.65 x 2 = 3.3 km in 2 minutes
Answer:
Notebook = $2.75
Pencil = $1.25
Markers = $ 0.50
Step-by-step explanation:
Stan:
n + 3p + 2m = 7.5
Jan:
2n + 6p + 5m = 15.50
Fran:
n + 2p + 2m = 6.25
Stan - Fran:
p = 1.25
Lets replace p with 1.25
n + 3(1.25) + 2m = 7.5
2n + 6(1.25) + 5m = 15.50
n + 2(1.25) + 2m = 6.25
Simplify
n + 3.75 + 2m = 7.5
2n + 7.5 + 5m = 15.50
n + 2.50 + 2m = 6.25
n + 2m = 3.75 stan
2n + 5m = 8 jan
n + 2m = 3.75 fran
stan = fran
jan - 2(stan)
m = 0.5
n = 2.75
Answer: The required probability is 
Step-by-step explanation:
Since we have given that
Number of spruce tree = 20
Number of maple tree = 50
Total trees = 70
We need to find the experimental probability that the next tree Colleen to get a spruce tree.
So, the probability would be :

Hence, the required probability is 
Answer: 46
Step-by-step explanation:
Answer:
Ques 1 - 
Ques 2 - 
Step-by-step explanation:
Ques 1: From the table, we see the relation,
5 = 2 × 2 + 1
9 = 2 × 4 + 1
13 = 2 × 6 + 1
17 = 2 × 8 + 1
21 = 2 × 10 + 1
That is, the relation from the table is given by,
, where x is the input and y is the output.
Hence, the required equation is
.
Ques 2: From the table, we see that,
2 = 12 × 0 + 2
14 = 12 × 1 + 2
26 = 12 × 2 + 2
38 = 12 × 3 + 2
50= 12 × 4 + 2
That is, the relation from the table is given by,
, where x is the input and y is the output.
Hence, the required equation is
.
