This year, druehl, inc., will produce 57 comma 60057,600 hot water heaters at its plant in delaware, in order to meet expecte

daser333 [38]

We know that:

rate = 0.15 heaters /labor hour

labourer time = 160 hours / month

goal = 57,600 heaters / year

We can solve this problem by simply looking at which ratios will cancel out the units:

number of labourers = (57,600 heaters/year) / [(0.15 heaters /labor hour) * (160 hours/month) * (12 month/year)

number of labourers = 200

Part 2

The ordered pair is: (0.707, -0.707)

Part 3

sin (-45°) = -√2/2
cos (-45°) = √2/2
tan (-45°) = -1

Ethan finds some dimes and quarters in his change purse. How much money (in dollars) does he have if he has 12 dimes and 4 quart

Masja [62]

So a dime is .10 or 10 cents

a quarter is .25 or 25 cents

12(.10)=$1.2

4(.25)=1

the equations would be

.25(x)

.10(x)

and if you need them combined it would be

.25(x) + .10(x)

A ball is thrown from an initial height of 3 feet with an initial upward velocity of 21 ft/s. The ball height h (in feet) after

Alexxx [7]

Answer:

Step-by-step explanation:

The position equation is given as

$s(t)=-16t^2+21t+3$ and we are looking for the times when the position of the ball is 9 feet. That means that we simply plug in a 9 for s(t) and factor to solve for t:

$9=-16t^2+2t+3$ and

$0=-16t^2+21t-6$ and this is what we factor to find t:

t = .42 sec and then again on its way back down at t = .89 sec
