Answer is: 50.4%. You have to take 30% off of 72%. Easiest way is to find 10% of 72 (7.2) and multiply that by 3 (=21.6). Then minus this off the original price (72 - 21.6 = 50.4)
Answer:
5.0 ft - 5.6 ft
Step-by-step explanation:
Given that the structure is to be made using two 12 foot boards, then we expect the total perimeter to be equal to (2*12)= 24 ft.
Using the angle of elevation, 40° and the width of 8 ft then you can apply the formula for tangent of a triangle where ;
Tan α = opposite side length/adjacent length
Tan 40°= h/8
h= 8 tan 40° = 6.71 ft
Applying the cosine of an angle formula to find the length of the sliding side
Cosine β = adjacent length /hypotenuse
Cosine 40°= 8/ sliding side length
sliding side length = 8/cosine 40° =10.44 ft
Checking the perimeter = 10.44 +8+6.71= 25.15 ft
This is more than the total lengths of the boards, so you need to adjust the height as;
24 - 18.44 = 5.56 ft ,thus the height should be less or equal to 5.56 ft
h≤ 5.6 ft
The answer is 3/5.
Continue this pattern and you'll see that it follows this geometric sequence
Answer:
y = -3x + 6
Step-by-step explanation:
First, this is your current equation: y= -3x+b. Fill in one of your coordinates into the equation (it doesn't matter which one because they're both the same). It should look like this: 3 = -3(1) + b. Multiply -3 and 1 to get -3. So, this is what it should look like: 3 = -3 + b. Add 3 to both sides to get your y-intercept of 6. Go back to your original equation and plug in 6 to b. This is your final equation: y = -3x + 6. Hope this helped!
