Answer:
55 degree
Step-by-step explanation:
ABC is 110 degree
According to question,
ABD= 1/2 * ABC
ABD= 1/2*110
ABD=55
Answer: The number of hours is the independent variable
Explanation: The number of miles depends on the number of hours.
Then, miles -> depentend variable, hours -> independent variable
The maximum height is 36.75feet at 2.5 seconds. Using the quadratic equation, you can calculate the x coordinate of the vertex with -b/2a. In this case, the x coordinate of the vertex is the time the swipe card reaches its max height , and it is 2.5. To calculate the maximum height, substitute 2.5 into each variable of t in the original equation, and the solution is 36.75.
Answer:
B
Step-by-step explanation:
The figure is a trapezium with area (A) calculated as
A = h (a + b)
where h is the perpendicular height and a, b the parallel bases
Here h = 8, a = 10 and b = 6, thus
A = × 8 × (10 + 6) = 4 × 16 = 64 cm² → B
