6+5=11+5=16+5=21
3+6=9+6=15+6=21
It will take Marco and Sophie 3 hours to get the same amount of money. The amount of money they will have will be $21.
Answers:
x = 24
y = 8√3
Explanation:
1) Since, the given triangle is a right triangle, and you have both an angle and the hypotenuse length, you can use some trigonometric ratios to find the variables.
2) The variables given represent:
x: adjacent-leg to angle 30°
y: opposite length to angle 30°
3) sine ratio:
sin 30° = opposite-leg / hypotenuse = y / (16√3)
⇒ y = 16√3 sin 30° = 16√3 × (1/2) = 8√3
4) cosine ratio
cos 30° = adjacent-leg / hypotenuse = x / (16√3)
⇒ x = 16√3 cos 30° = 16√3 (√3 / 2) = 16 × 3 / 2 = 24
Answer:
1. Dividing both sides by 4
2. Adding 3 to each side
Step-by-step explanation:
The first step you want to take is to divide both sides by 4 so that you can solve for inside the parenthesis. Next, you should add three to both sides in order to isolate the variable.
Answer:
#1 is 28
Step-by-step explanation:
Set the perimeters equal, as 6x - 2 = 8x - 12, solve for x = 5, and plug in.
