If a job pays $10 per hour, how much would it pay for 15 minutes?

Pavel [41]

<h3>Answer: $2.50</h3>

Explanation:

15 minutes is 1/4 of an hour. This means we'll divide the hourly wage by 4

10/4 = 2.50

Side note: This assumes that your boss is paying in 15 minute increments (or some other fractional amount of an hour). However, your boss may only pay for full hours only.

A ball is launched straight up in the air from a height of 6 feet. Its velocity (feet/second) t seconds after launch is given by

german

Step-by-step explanation:

A ball is launched straight up in the air from a height of 6 feet. The velocity as a function of time t is given by :

f(t) = -32 t+285

Height of the ball is :

$h(t)=\int\limits{f(t){\cdot} dt}\\\\h(t)=\int\limits{(-32t+285){\cdot} dt}\\\\h(t)=-16t^2+285t+C$

C is constant. Here the ball is launched from a height of 6 feet. So,

$h(t)=-16t^2+285t+6$

At t = 2 s, $h(t)=-16(2)^2+285(2)+6=512\ m$

At t = 9 s, $h(t)=-16(9)^2+285(9)+6=1275\ m$

Between 2 s and 9 s, the ball's height changed is : 1275 - 512 = 763 m.

Solve the following equation. Then place the correct number in the box provided.

zvonat [6]

Answer:

Step-by-step explanation:

$\dfrac{2x}{5}+1=7$

Subtract 1 from both sides:

$\dfrac{2x}{5}=6$

Multiply both sides by 5:

$2x=30$

Divide both sides by 2:

$x=15$

Please help, I’m so confused!

Anna11 [10]

Answer:

$a = c/(d-r)$

Step-by-step explanation:

To solve for $a$ , first multiply by $a$ on both sides to get this:

$c = da - ra$

Now, you can factor out an $a$ from the right side to get this:

$c = a(d - r)$

Now divide by $d - r$ in order to solve for $a$ and you get:

$a = c/(d-r)$
