From information given Lisa bought three items.
10 + 20 + 23 = 53 dollars ( which is total pre- tax cost)
The sales tax rate is at 7.2% . Value of this tax in dollars will be:
7.2 % of 53 → (7.2 / 100) × 53 → 0.072 × 53 = 3.816
So the tax rate value is 3.816
Total cost of items will be 53 + 3.816 = 56. 816
Rounded off to the nearest cent 56.816 = 56.80
Therefore Lisa paid a total of $ 56.80
Answer: y=3x-7
Step-by-step explanation:
First you have to get the equation in slope intercept form by moving x over then dividing by -1 because y cannot be negative
Then since you're trying to find the line that is parallel you use the same slope which is 3x
You then plug in the points which is 2=3(3) + b for you are trying to find teh y intercept
You then solve as normal and get y=3x-7
I am pretty sure this is correct

Answer:
Perimeter = 38
Step-by-step explanation:
Recall: when two tangents are drawn to meet at a point outside a circle, the segments of the two tangents are congruent.
Given,
CQ = 5
PQ = 10
PR = 14
Perimeter of ∆PQR = RC + CQ + QB + BP + PA + AR
CQ = QB = 5 (tangents drawn from an external point)
BP = PQ - QB
BP = 10 - 5 = 5
BP = PA = 5 (tangents drawn from an external point)
AR = PR - PA
AR = 14 - 5 = 9
AR = RC = 9 (tangents drawn from an external point)
✔️Perimeter of ∆PQR = RC + CQ + QB + BP + PA + AR
= 9 + 5 + 5 + 5 + 5 + 9
Perimeter = 38

<h3>What is Unitary Method?</h3>
Unitary method is a process by which we find the value of a single unit from the value of multiple units and the value of multiple units from the value of a single unit.
Mark spent 1 hour 17 minutes less than Sheila
Sheila spent 55 minutes less than Pete.
Pete spent 3 hours reading.
Since, pete spent 3 hours. So, Sheila spent
= 3 hours or (180 minutes) - 55 minutes
= 2 hours 05 minutes.
Now, Mark spent = 2 hrs 05 minutes - 55 minutes
= 1 hour 10 minutes
