65%

There are only 7 numbers that don't fit this criteria. Therefore, there are 13 that do. 13/20 = .65*100 = 65%

Even numbers always end with a digit of 0, 2, 4, 6 or 8. The set of even numbers between 1 and 20 are 2,4,6,8,10,12,14,16,18.The  numbers which are multiples of 3 and lie between 1 and 20 are 3,6,9,12,15,18.

Total numbers which are even and multiple of 3 between 1 and 20 are 2,3,4,6,8,9,10,12,14,15,16,18. There are 13 numbers in all.

There are 20 numbers between 1 and 20.

Probability of picking  an even number number or a multiply of three = \frac{13}{20}

The area of the base of a cube is 36 in2.<br> What is the total surface area of the cube?
irina [24]
216 in^2 ( its 2 squared but that’s how I can write it on my phone)

All the sides of a cube are the same and there are 6 sides to a cube so if we have 36 as our are of the base then we just have to multiply that by 6

36 x 6= 216

Triangle F G E is shown. Angle F E G is a right angle. The length of hypotenuse F G is 18.6 inches and the length of F E is 12 i
Delicious77 [7]

Answer:

Measure of ∠FGE is 40.2°.

Step-by-step explanation:

Refer to the attachment.

Consider ΔFGE. Given that ∠FEG = 90° and ∠FGE is x°.

To find the value of ∠FGE use trigonometric ratios.

Use sine ratio to find the value of ∠FGE.

\sin \theta=\dfrac{opposite\:side}{hypotenuse\:side}

Rewriting it in terms of x° as follows,

\sin x=\dfrac{opposite\:side}{hypotenuse\:side}

Now find the opposite and hypotenuse side of the angle ∠FGE.

So opposite side of ∠FGE is FE and hypotenuse side of ∠FGE is FG.

Substituting the values,

\sin x=\dfrac{FE}{FG}

Given that length of FE is 12 inch and FG is 18.6 inch.

Substituting the value,

\sin x=\dfrac{12}{18.6}

To find the value of x, taking inverse sin.

x=\arcsin \left(\dfrac{12}{18.6}\right)

Calculating the value,

x=40.17

Rounding to nearest tenth the value of angle is 40.2

Therefore measure of ∠FGE is 40.2° .

Mkey [24]

Answer:

1,015

Step-by-step explanation:

7 pounds of honey equals 1 pound of wax

So if we have 145 pounds of was, we multiply 145 by 7

145x7= 1,015

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>
