Answer:
Yes
Step-by-step explanation:
This is because 46 multiplied by 1.06 equals 48.76, which is under $50.
Let the number of two-hour lessons be x and the number of one-hour lessons be y; this gives us the equations
2x + y = 25
50x + 30y = 690
To find x and y, we can solve the quadratic equation provided;
from the first equation:
y = 25 - 2x.......i
By substituting equation i into the second equation, we arrive at:
50x + 30(25 - 2x) = 690
50x + 750 - 60x = 690
-10x = -60
So,
x = 6
Thus, we find that the total number of two-hour lessons is 6 hours.
The result is $15,625
The full price represents 100%. A local college bookstore spent $12,500, which equates to 80% of the full price as this reflects a 20% discount (100% - 20% = 80%).
Now, let’s set up a proportion.
If $12,500 corresponds to 80% of the full price, what is the full price (100%):
$12,500: 80% = x: 100 %
x = $12,500 · 100% ÷ 80% = $15,625
An acute triangle is defined as one in which all angles are acute. An acute angle is defined as having a degree measurement of less than 90. Thus, Charlene's definition is valid.
