Answer:
The object will hit the ground after <u>9 seconds</u>.
Step-by-step explanation:
Given:
The height 'h' of an object varies with time 'x' as:
Now, we are asked to find the time 'x' when the height reaches ground after launch.
So, the height of the object on reaching ground will be 0 m. So, substituting 0 for 'h' and solving for 'x', we get:
Therefore, there are two values of 'x' for which height is 0. The negative value is ignored as time can't be negative.
So, the value of 'x' is 9 seconds.
Hence, the object will hit the ground after 9 seconds.
Answer:
Area of given figure = 488 cm²
Step-by-step explanation:
Given:
Length of rectangle = 22 cm
Width of rectangle = 17 cm
Base of triangle = 19 cm
Find:
Area of given figure
Computation:
Height of triangle = 22 cm - 10 cm
Height of triangle = 12 cm
Area of given figure = Area of rectangle + Area of triangle
Area of given figure = [l x b] + (1/2)(b)(h)
Area of given figure = [22 x 17] + (1/2)(19)(12)
Area of given figure = 374 + 114
Area of given figure = 488 cm²
Answer:They both are correct.
Step-by-step explanation: If the hour and minute hand point on the same thing, they both stand for the same thing. For example, if both hands were pointing at the number 9, the time would be 9:45.
100% = 1
Therefore, 200% = 2
8.5 x 2 = 17
∴ 200% of 8.5 = 17
Answer:
C. 15
Step-by-step explanation:
Your gonna want to divide the volume by the conversion ratio. The volume to liters is equivalent to the millileters divided by 1000. :)
