False, variables can only be expressed through letters
Answer:
Postcards bought was 9
Step-by-step explanation:
<h3>
<u>P = 3D</u></h3>
where,
- P = total number of postcards
- D = days of vacation = 3 days
⟼ P = 3D
prince number of days of vacation is 3 therefore we multiply 3 by 3
⟼ P = 3(3)
multiply 3 by 3
⟼ P = 9
Jared bought 9 postcards
Answer:
Ratio is 236 : 241
Step-by-step explanation:
Lake County’s smallest forest preserve is 472 acres. Orange County’s smallest preserve is 482 acres
Lake County’s smallest forest = 472
Orange County’s smallest = 482
To find ratio we make a fraction
Ratio = Lake County’s forest / Orange County’s forest
= 
Now simplify the fraction
divide top and bottom by 2

Ratio is 236 : 241
Note that
(4sqrt3)^2 = (2sqrt3)^2 + 6^2 [ 48 = 12 + 36] so the triangle is a right angled one with hypotenuse AB
So angle C = 90 degrees
sin A = 2 sqrt3 / 4 sqrt3 = 1.2 giving A = 30 degrees
and B = 90 - 30 = 60 degrees
A = 30, B = 60 and C = 90 degrees
