MATHEMATICS HIGH SCHOOL

A school has $ 15,000 to spend on computer monitors the school plans to purchase 200 monitors for $89 each a teacher completes the calculations below and concludes that the has enough money to buy the monitors 200 times 89 = 200 times 8 + 200 times 9 = 1,600 +1,800 =3,400

Answers

Answer 1
Answer:

Answer:

They cannot afford the monitors

Step-by-step explanation:

Given that the cost of a monitor is $89

and the school is willing to buy up to 200 monitors

We can calculate the total cost of all the 200 monitors as

200*89= $17,800

Given that the school only has $ 15,000 to spend on the monitor

they cannot afford the amount as they still have a deficit of $2,800

An auto weighing 2,500 pounds is on a street inclined at 10 with the horizontal. Find the force necessary to prevent the car from rolling down the hill. Round your answer to the nearest whole number. Do not use a space or decimal in your answer or it will be marked wrong.

Answers

Answer:

13892 lb-ft/sec^2

Step-by-step explanation:

Given that An auto weighing 2,500 pounds is on a street inclined at 10 with the horizontal.

Here acceleration due to gravity is the pulling factor against which the car should be stopped from rolling down the hill.

Weight of the car =2500 pounds

Vertical component of gravity = 32cos (90-10)=32sin 10 = 32(0.1736)

Force required = mass x acceleration

=2500x0.1736x32

=13892 lb ft/sec^2
Make sure your calculator is set to DEGREES and not RADIANS when performing your sinθ calculation. sin(10) = -0.54402 sin(10°) = 0.17365 You could also try using trig tables if you're unsure how to do this. So: 2500sin(10°) = 434 lb
