I still cant see it sorry cant help without seeing it can you spell the question?
Answer:
63/24
Step-by-step explanation:
First you change the whole 2 to have a fraction of 48/24.
Next you have change 5/8 so its denominator has a 24. So you multiple the 8 by 3 to get 5/24. But then you have to multiply the 5 by 3 also so it is still the same fraction just bigger and you get 15/24. Now add the 15/24 with 48/24 to get 63/24.
Hope this helps!
Answer:
You replace y with f(x)
Step-by-step explanation:
- Function is a relation between two sets of numbers, with every element
in the first set has only one corresponding element in the second set
- The first set is called the domain of the function (input)
- The second set is called the range of the function (output)
- If the first set is set X and the second set is set of Y, then each value
of x has only one value of y and x is the input and y is the output
- Function notation is the way to write a function f(x) = y, where f(x)
represents the values of y
∵ y = 2x + 1
∵ f(x) = y
- Replace y by f(x)
∴ f(x) = 2x + 1
* <em>You replace y with f(x)</em>
The diameter is 2x the radius. The radius 5 (x). 2(5) =10. Diameter= 10.
What is the MA of a 1st class lever?It can be any number > 0.What is the MA of a 2nd class lever?Always > 1What is the MA of a 3rd class lever?Always < 1 (it has to be > 0)A 58-tooth gear turns five times. It is connected to a 16-tooth gear. How many times does the 16-tooth gear turn?<span>TONO = TINI
TO = TINI ÷ NO
= 5 turns . 58 teeth ÷ 16 teeth
= 18.13 turns</span>A ramp with a mechanical advantage of 6.75 lifts objects to a height of 2.45 meters. How long is the ramp?<span>L = MAxH
= 6.75 . 2.45 m
= 16.54 m</span>A 65-tooth output gear is connected to a 24-tooth input gear. What is the MA of this system? Is force or speed multiplied?<span>MA = No ÷ Ni
= 65 teeth ÷ 24 teeth
= 2.71
Force is multiplied since MA > 1</span>A ramp that is 13.2 meters long is used to lift a 755 newton box up to a height of 1.11 meters. What is the MA of the ramp?<span>MA = L ÷ H
= 13.2 m ÷ 1.11 m
= 11.89</span>A lever can lift a 358 newton rock with a force of 93 newtons. If the length of the output arm is 1.45 meters, what is the length of the input arm?<span>MA = OF ÷ IF
= 358 N ÷ 93 N
= 3.85
IA = MAxOA
= 3.85 . 1.45 m
= 5.58 m</span>List the 7 types of simple machinesLever, pulley, wheel & axle, screw, wedge, ramp, gearDraw a pulley system with an MA of 3Look at the middle pictureDraw 2 different ramps. Mark the one with a greater MA with a star. How do you know it has the greatest MA?A has the greatest mechanical advantage since it is the most gently sloped. The steeper it is, the more force you have to apply, and the less MA it has.A machine is required to produce an output force of 1,357 newtons. If the machine has a mechanical advantage of 5.5, what input force must be applied to the machine?<span>IF = OF ÷ MA
= 1,357 N ÷ 5.5
= 246.73 N</span>What is the mechanical advantage of a wheel if the radius of the wheel is 34.95 cm and the radius of the axle is 8.2 cm?<span>MA = WR ÷ AR
= 34.95 cm ÷ 8.2 cm
= 4.26</span>What does MA tell you?MA tells you how much your input force is multiplied. It tells you how "easy" your task is. Remember you must trade less force for greater distanceWhich is greater, work output or work input? Why?Work input is greater due to FRICTION!An output gear turns 15 times. How many times will the input gear turn if the gear ratio is 30?<span>Ti = To ÷ GR
= 15 turns ÷ 30
= 0.50 turns</span><span>
