Answer:
191=266+109x
Step-by-step explanation:
It says 191 is the same as 266 added to the product of 109 and _____. i am guessing you meant to say a variable.

Where is the graph? can you include the graph
Answer:
Time taken for the ball to hit the ground back = 3.08 s
Step-by-step explanation:
h(t)= -16t² + 48t + 4
when will rhe object come back to hit rhe ground?
When the ball is at the level.of the ground, h(t) = 0.
0 = -16t² + 48t + 4
-16t² + 48t + 4 = 0
Solving the quadratic equation
t = 3.08 s or t = -0.08 s
Since the time cannot be negative,
Time taken for the ball to hit the ground back = 3.08 s
Hope this Helps!!!
Step-by-step explanation:
From the question, we know that the solutions of the system
is (14,6), which means the speed of the the boat in calm water,
, is 14
, and the speed of the current,
, is 6
. To summarize:
and
We also know that w<span>hen the boat travels downstream, the current increases the speed of the boat; therefore to find the speed of the boat traveling downstream, we just need to add the speed of the boat and the speed of the current:
</span>
<span>
Similarly, to find the the speed of the boat traveling upstream, we just need to subtract the speed of the current from the speed of the boat:
</span>
<span>
We can conclude that the correct answer is </span><span>
C. The team traveled at 8 km per hour upstream and 20 km per hour downstream.</span>
Jane and Ken share some money in the ration 5:3 Ken's share is $16 less than Jane's share. FInd each person's share.
The money is shared in the ratio 5:3
That means that Jane gets 5 parts of the total money and Ken gets three parts.
So then there are 8 parts of the money (5 + 3 = 8)
Jane has 2 parts more than Ken (5 - 3 = 2)
And those 2 parts are equal to $16 (the question says so)
So one part is equal to $8
Each person's share then is: Jane has 5 parts = $40, Ken has 3 parts = $24
