Match each expression to the scenario it represents.
1 answer:
The expression matched with each scenario is;
Scenario 1: 0.82x
Scenario 2: 1.18x
Scenario 3: 7/10x
Scenario 4: 13/10x
<h3>Algebra</h3>The price of a game that’s been discounted
18% off its list price (x)
Total price = x
Discount = 18%x = 0.18x
New price = x - 0.18x
= 0.82x
The price of a toy that sells for 18% more
than the amount (x) needed to build the toy
Original price = x
Percentage increase = 18%x = 0.18x
New price = x + 0.18x
= 1.18x
The volume of water remaining in a tank after 3/10 of its original volume (x) is drained out
Original volume = x
Volume drained = 3/10x
New volume = x - 3/10x
= 7/10x
The total amount of flour in a bakery after receiving new stock equal to 3/10 of its current stock (x)
Original stock = x
New stock = 3/10x
Total stock = x + 3/10x
= 13/10x

Answer: Option D.
Step-by-step explanation:
To solve this exercise you must keep on mind the Angle at the Center Theorem.
According to the Angle at the Center Theorem, an inscribed angle is half of the central angle.
Therefore, given in the inscribed angle m∠BAC=35°, you can calculate the central angle m∠EFD as following:
- Solve for EFD.
- When you substitute values. you obtain:
