The point-slope form is y - y1 = m(x - x1) where x1 ad y1 are the coordinates given and the m is the slope, which is given also. Plugging these in, we have
y - 4 = -2(x - (-1)), which simplifies to y - 4 = -2(x + 1)
Answer:
sail a = 81ft²
sail b base = 12ft
Step-by-step explanation:
question 5:
the measurements for sail A are 18ft(height) and 9ft (base)
the formula to find the the area of a triangle is (b · h) 1/2
(9 · 18) 1/2 = (162) 1/2 = 81
so ahmad will need 81ft² of fabric for sail a
question 6:
we know that the formula to find the area of a triangle is (b · h) 1/2 = a, since we know the height and the area of the triangle we plug them into the equation to find the measurement of the base.
(b · 18) 1/2 = 108
= 108/ 1/2
(b · 18) = 216
18b = 216
18b/18 = 216/18
b= 12
check your work:
(12 · 18) 1/2 = 108
(216) 1/2 = 108
108 = 108 true!
the base measurement for sail b is 12ft
hope this helps and have a great day!!
If there are 1,400,000 drops in 25 gallons:
1 drop = 25 gallons : 1,400,000 = 0.0000178 gallons
It is 0.00178 % of a gallon.
