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!!
ANSWER
The volume at the end of one week will be 22.32 liters.
EXPLANATION
If the balloon with a small leak loses 1% of its volume each day, then by the end of one week, it will lose 7℅ of its volume.
If the balloon originally contains 24 liters of gas, then this corresponds to 100%.
The volume at the end of one week will correspond to (100-7)%=93%
The volume at the end of one week is
