What i do is i take the original number of students and multiply by 40% then i will add it to 18. Then i will do the same thing to 37.5%.

What is 1/8 divided by 2

slavikrds [6]

When dividing 1/8 by 2
we have to first take the reciprocal of 2
reciprocal is when the numerator and denominator are exchanged
2 when written as a fraction is $\frac{2}{1}$
we need to find the reciprocal of $\frac{2}{1}$ which is $\frac{1}{2}$
then
$\frac{1}{2} of \frac{1}{8}$
when 'of' function is used it means to multiply the 2 fractions
when multiplying fractions multiply the numerators by numerators and multiply denominators by denominators
is $\frac{1}{2} * \frac{1}{8} = \frac{1}{16}$
answer is $\frac{1}{16}$

The path of a projectile launched from a 20-ft-tall tower is modeled by the equation y = -5x2 + 40x + 20. What is the maximum he

Otrada [13]

Answer:

30.49 m

Step-by-step explanation:

To obtain the maximum height, we solve for the value x when dy/dx = 0.

Since, y = -5x² + 40x + 20

dy/dx = d[-5x² + 40x + 20]/dx

dy/dx = -10x + 40

Since dy/dx = 0,

-10x + 40 = 0

-10x = -40

x = -40/-10

x = 4

Substituting x = 4 into the equation for y, we have

y = -5x² + 40x + 20

y = -5(4)² + 40(4) + 20

y = -5(16) + 160 + 20

y = -80 + 160 + 20

y = 80 + 20

y = 100 ft

Since y is in feet, we convert to meters.

Since 1 m = 3.28 ft, 100 ft = 100 ft × 1 m/3.28 ft = 30.49 m

So, the maximum height, in meters reached by the projectile is 30.49 m

Describe in words how you would solve<br><br>the linear system y = 3x + 1 and y = - 2x + 3.

disa [49]

Answer:

Below.

Step-by-step explanation:

As both the right sides of the 2 equations are equal to y, by the transitive law of equality 3x + 1 = -2x + 3.

W then solve this equation for x then substitute this value of x in the first equation ( y = 3x + 1) to find the value of y.
