We can set up a proportion to figure out how many laps out of 200 laps is 57% out of 100%
Cross multiply
The answer is 114 laps.
Answer:
4 inches should be turned up on both sides.
Step-by-step explanation:
In order to find this, create a situation in which we give the amount turned up on each side as x. Then give the amount that isn't turned up as 16 - 2x (since 2x is the amount turned up). Now we can find the area by multiplying the 3 measurements.
100 * x * (16 - 2x) = MAX
100 * (16x - 2x^2) = MAX
-200x^2 + 1600x = MAX
Now that we have a quadratic function, we can find the maximum value of x by using the vertex formula for x values (-b/2a).
x = -b/2a
x = -1600/2(-200)
x = -1600/-400
x = 4
Answer:
x=7.999996
Step-by-step explanation:
273x=81x+10
log(273x)=log(81x+10)(Take log of both sides)
3x*(log(27))=(x+10)*(log(81))
3x=(
log(81)
log(27)
)*(x+10)
3x=1.333333*(x+10)
3x=1.333333x+13.33333(Simplify both sides of the equation)
3x−1.333333x=1.333333x+13.33333−1.333333x(Subtract 1.333333x from both sides)
1.666667x=13.33333
1.666667x
1.666667
=
13.33333
1.666667
(Divide both sides by 1.666667)

Step-by-step explanation:
-2x-10=8
-2x=8+10
X= -18/2
hence X= -9
Answer: 11+7i
