Do the power rule first in the first expression then add the answer on the second expression do 4 squares add 5 then subtract the two numbers
Starry Crown charges (138 dollars)/(4 hours) = (138/4 dollars)/hour = (34.50 dollars)/hour
Solar R Us charges (143 dollars)/(5 hours) = (143/5 dollars)/hour = (28.60 dollars)/hour
Lights On Us charged (157 dollars)/(6 hours) = (157/6 dollars)/hour = (27.17 dollars)/hour
Lights On Us has the best rate.
Answer:
Step-by-step explanation:
Looking at the right angle triangle that contains x and y, we would apply trigonometric ratio to determine x an y. Taking 60 degrees as the reference angle,
Hypotenuse = y
Adjacent side = x
Opposite side = 36
Therefore,
Sin # = opposite side / hypotenuse
Sin 60 = 36/y
y = 36/Sin60 = 36/0.8660 = 41.57
Cos # = adjacent side/hypotenuse
Cos 60 = x/41.57
x = 41.57Cos 60 = 41.57 × 0.5 = 20.785
Sin45 = z/36
z = 36Sin45 = 36 × 0.7071 = 25.4556
Answer:
150
Step-by-step explanation:
First you have to find what number 80 is 2/5 of, to do this do the reciprocal of 2/5 which would be 5/2. Multiply 80 by 5/2 and you'll get 200, then find what 3/4 of 200. Multiply 200 by 3, then divide by 4 to get the answer of 150.
