30 60 90 right triangle
leg = 6 so other leg = 6√3
A = (1/2)(6+6)( 6√3+ 6√3)
A = 6 (12√3)
A = 72√3
answer is D
72√3
First, we have to add the fractions.
1/3 + 1/4 = 7/12
12 - 7 = 5
She earns 5/12 of her paycheck on Wednesday
From 2000 students paying $50 a year, they make $100,000. Lets say the 3 students who get in serious trouble with health use the whole policy of $12,000. thats $36,000. So the insurance company made $64,000 profit.
Standard form : Ax + By = C
y = 2/3x + 1
-2/3x + y = 1....multiply by -3
2x - 3y = -3 <=== standard form
Truck speed be x
car travel at x+19
they travel in opposite directions
so the separation is (x+x+19) * no. of hours
1048 = (2x+19)*8
x = ((1048/8) - 19)/2
=56
truck speed is 56 miles per hour
car speed is 56+19 = 75 miles per hour
