At a large university, A total of 5,400 students are enrolled in a math class this semester. This represents 60% of the total nu

Brut [27]

Answer:

c. 9,000 students

Step-by-step explanation:

Step 1: Set up the equation

$\frac{60}{100} x = 5400$

Step 2: Simplify both sides of the equation.

$\frac{3}{5} x = 5400$

Step 3: Multiply both sides by 5/3.

$\frac{5}{3} *\frac{3}{5} x = \frac{5}{3} * 5400$
$x = \frac{27000}{3}$
$x = 9,000$

Therefore, the correct answer is c. 9,000 students.

0.23x + 1.47 = 0.37x – 1.05

Artyom0805 [142]

0.23x+1.47=0.37x-1.05

-1.47 -1.47

0.23x=0.37x-2.52

-0.37 -0.37

-0.14x=-2.52

/-0.14 /-0.14

x=18

A projectile is fired into the air with an initial vertical velocity of 160 ft/sec from ground level. How many seconds later doe

djverab [1.8K]

The maximum height of the projectile is the maximum point that can be gotten from the projectile equation

The projectile reaches the maximum height after 5 seconds

The function is given as:

$\mathbf{h(t) = -16t^2 + 160t}$

Differentiate the function with respect to t

$\mathbf{h'(t) = -32t + 160}$

Set to 0

$\mathbf{h'(t) = -32t + 160 = 0}$

So, we have:

$\mathbf{-32t + 160 = 0}$

Collect like terms

$\mathbf{-32t =- 160 + 0}$

$\mathbf{-32t =- 160}$

Solve for t

$\mathbf{t = \frac{- 160}{-32}}$

$\mathbf{t = 5}$

Hence, the projectile reaches the maximum after 5 seconds
