66 and 2/3 is equal to 66.75%......multiply 300x0.6675 to get your answer of 200.25. Subtract 200.25 from 300 and you have your answer
Answer:
y = -6/5
Step-by-step explanation:
Remove parentheses
2y - 2 - 7y = 4
group like terms
2y - 7y - 2 = 4
add similar elements
-5y - 2 = 4
add 2 to both sides
-5y - 2 + 2 = 4 + 2
simplify
-5y = 6
divide both sides by -5
-5y ÷ -5 and 6 ÷ -5
simplify
y = -6/5
B. The estimate and the exact product are 0.852 away from each other making it the closest estimate
Answer:
time = 1secs
<em>Max height = 25metres</em>
Step-by-step explanation:
Let the equation that models the height of the ball be expressed as;
h(t) = −16t^2 + 32t + 9
t is the time in seconds
The velocity of the ball at its maximum height is zero i.e dh/dt = 0
dh/dt = -32t + 32
0 = -32t + 32
32t = 32
t = 32/32
t = 1 seconds
The ball will reach its maximum height after 1 seconds.
Get the maximum height reached. Substitute t = 1 into the modeled function;
h(t) = −16t^2 + 32t + 9
h(1) = −16(1)^2 + 32(1) + 9
h(1) = −16 + 32 + 9
h(1)= 16+9
<em>h(1) = 25</em>
<em>Hence the maximum height reached is 25metres</em>
