Answer:

Step-by-step explanation:
A rational number Q can be expressed in the form
where a and b can take any integer value except b = 0
This is because it would lead to division by zero which is undefined.
Yes that is outstanding work
Step-by-step explanation:
A)
Janet's took 34.56 seconds to cover 50m freestyle swim.
In words it could be said as: thirty four and fifty six hundredths.
B)
Race # Time (in sec.) time( after roundoff to nearest integer)
<em> 1 34.56 35</em>
<em> 2 35 35</em>
<em> 3 34.8 35</em>
4 34.137 34
5 33.92 34
Hence, the first 3 race times were equal after rounding off to nearest integer.
C)
on arranging the time of Janet's from fastest to slowest we get the table as:
Race # Time( in sec.)
5 33.92
4 34.137
1 34.56
3 34.8
2 35
since, after decimal we arrange the numbers in order same as we do for the natural numbers.
as in race #5 '33' is the smallest among all hence we keep it in first place.
for race 4,1 and 3 we have the same digit before decimals so now we have to look for the number after decimals.
D)
Janet's time in race #4 was: 34.137 sec.
But Grace was 1.8 seconds faster than Janet.
Hence, Grace time=34.137-1.8=32.337 sec.

Answer:
Sally's Monthly payment = $166.70
Step-by-step explanation:
The price of the boat including tax = $5275
The down payment = $500
Remaining amount = $5275 - $500 = $4775
She has to take loan for $4775
P = $4775,
Rate per montly =15%/12 = 15/100 ÷12 = 0.15÷12 =0.0125
n =36 months
Here we have to use the formula
Monthly payment = [p*r*(1+r)^n ÷ (1 + r)^n - 1]
= (4775*0.0125*(1+0.0125)^36 / (1+0.0125)^36 - 1)
= (59.6875*1.0125^36) ÷ [(1.0125)^36 -1]
= 93.35 ÷ [ 1.56 -1]
=93.35 ÷ 0.56
= $166.70
Monthly payment = $166.70
Thank you.
