Answer: 54cm
Step-by-step explanation:
We can break the shape up into a right angled triangle and a square;
Area of square = 6^2 = 36
Area of triangle = 1/2 x 6 x 6 = 18
We add both the answers up at get 54.
Similar to the last problem
y = x + 2
y + 3 = 2x
so we need to find which values fit
check out B and D - its one of those
Answer:
Step-by-step explanation:
Let x represent the amount invested at 11%. Then (3000-x) is the amount invested at 8%. The interest difference is ...
0.11x - 0.08(3000 -x) = 216
0.19x -240 = 216 . . . . . . . . simplify
0.19x = 456 . . . . . . . . . . . . add 240
456/0.19 = x = 2400 . . . . . the amount invested at 11%
3000-2400 = 600 . . . . . . . the amount invested at 8%
Answer:
x = 36√2
Step-by-step explanation:
Reference angle = 30°
Side length opposite to 30° = 12√6
Adjacent length = x
Apply TO A to find x.
Tan 30° = Opp/Adj
Tan 30° = 12√6/x
multiply both sides by x
x*Tan 30° = 12√6
Divide both sides by Tan 30°
x = (12√6)/Tan 30°
x = (12√6)/(1/√3) (tan 30° = 1/√3)
x = (12√6) × (√3/1)
x = 12√18
x = 12√(9*2)
x = 12*3√2
x = 36√2
