A 100-foot ramp is tilted at a 45° angle. How high is the top of the ramp from the ground?

1 answer:

4 0

Setting up a right triangle, the 100 would be the hypotenuse, the 45 would be the angle of elevation, and you're looking for the opposite side.
Sin 45 = x/100
100sin45 = x
100 * ✓(2)/2 = x
50 ✓2 =x
x = 50✓2 ft

Laura sold t-shirts at a festival. She made $4 for each t-shirt she sold. Her expenses were $25. If she made a profit of $71, ho

Mamont248 [21]

Answer:

24 t shirts

Step-by-step explanation:

revenue - expenses = profit

profit = $71

expenses = $25

revenue = money made from t shirts = $4 for each t shirt, x times (she makes $4 for each t shirt and sells x t shirts) = $4 * x

4 * x - 25 = 71

add 25 to both sides to isolate the variable and its coefficient

4x = 96

divide both sides by 6 to isolate x

x = 24
