Answer:
5/16 or 10/32
Step-by-step explanation:
A 2 digit number is such that thrice the sum of its digits is less than the value of the number by 8.
When the digits are reversed the number increases by 9.
Find the number.
Answer:
23
Step-by-step explanation:
Let "ab" represent the digits of the number.
"thrice the sum of its digits is less than the value of the number by 8"
The value of the number is 10a+b.
3(a+b) = (10a+b) - 8
3a+3b = 10a+b-8
7a-2b = 8
"When the digits are reversed the number increases by 9"
Value of "ba" = 10b+a
(10b+a) - (10a+b) = 9
9b-9a = 9
b-a = 1
b = a+1
7a-2(a+1) = 8
5a -2 = 8
a = 2
b = a+1 = 3
"ab" = 23

Step-by-step explanation:
The movie rental store CineStar offers customers two choices. Customers
can pay a yearly membership of $45 and then rent each movie for $2 or they can
choose not to pay the membership fee and rent each movie for $3.50. Which
would you choose and why?*
Answer:
The yearly fee + $2 per movie
Step-by-step explanation:
Because lets say you rent 50 movies per year. Well with the yearly fee its $145. But with no yearly fee and just $3.50 per movie it’s $175.
What is 14 out of 28 expressed as a fraction?
Answer:
14/28 is already a fraction but if you simplify it will be 1/2 or 50% as a percentage
Answer: 14/28 but 1/2 as a fraction in simplest form
Step-by-step explanation:
14*2=28 this means that 14 is half or one half of 28 which is why 1/2 is 14/28 in simplest form.
Only put 1/2 if you don’t see the fraction 14/28.
Hope this helps

A peep increased by 25% is a pop. A pop decreased by 40% is a slug, and a slug increased by 100% is a slap. What percent of a peep is a slap
Answer:
A slap is 120% of a peep
Step-by-step explanation:
We shall make use of values here
Let a peep be value of 100
A pop is 100 + 25% of 100
= 100 + 0.25(100) = 125
Pop = 125
A slug is pop deceased by 40%
= 125 - (40% of 125)
= 125-(50) = 75
A slap is a slug increased by 100%
= 75 + (100% of 75)
= 75 + 75 = 150
So now, we want to calculate percent of peep is a slap
That will be;
150/125 * 100%
= 120%

Step-by-step explanation:
In a study of 900 adults, 45 out of the 325 men in the study said that they preferred to rent a movie on DVD rather than going out to a movie theater. What is the approximate percentage of men in this study who prefer to rent a movie on DVD
Answer:
[tex]\%DVD = 14\%[/tex]
Step-by-step explanation:
Given
[tex]Population = 900[/tex]
[tex]Sample = 325[/tex] --- selected adults
[tex]Proportion = 45[/tex] --- those that prefer renting a movie
Required
Represent the proportion as a sample.
This is calculated as thus:
[tex]\%DVD = \frac{Proportion}{Sample} * 100\%[/tex]
[tex]\%DVD = \frac{45}{325} * 100\%[/tex]
[tex]\%DVD = \frac{45 * 100}{325}\%[/tex]
[tex]\%DVD = \frac{45 00}{325}\%[/tex]
[tex]\%DVD = 13.85\%[/tex]
[tex]\%DVD = 14\%[/tex] --- approximated

Part 1: Answer the following questions (20 points)
1. Name and describe the components needed to make a complete circuit.
2. Compare and contrast a series and parallel circuit. Give at least one way that they are alike and one way that they are different.
3. Ohm's law is represented by the equation I = V/R. Explain how the current would change if the amount of resistance decreased and the voltage stayed the same.
4. Define resistance and describe what would happen to a light bulb if the voltage increased but the resistance stayed the same.
Part 2: Design your own circuit (40 points)
Design a circuit and draw a circuit diagram using the proper symbols. Your circuit must contain a battery, a light bulb (if you would like to substitute another item that uses electrical power you may), a switch, an ammeter, and a resistor. After you draw your circuit, complete the questions which ask you to describe the circuit that you have created. You may hand draw the circuit and scan or fax the worksheet to submit for grading. Or you may use a draw/paint program to create your circuit in the space provided.
Circuit Diagram:
Question 1: Is the circuit you created a parallel, series or a series/parallel circuit? Support your answer with a description of this type of circuit.
Question 2: What is the purpose of the resistor in your circuit?
Question 3: How does the switch work?
Question 4: Describe the path of the electric current through your circuit.
Question 5: Explain how your battery works. (You may want to look at the Electric Current lesson) What are some possible materials you could use to make your battery?
Answer: part 1
1. You need a Source of electric power (battery or generator), a load to absorb the power (lamp, motor, heating coil) and wiring to connect the load to the power source!
2. they both give off electricity energy, and they are different because they dont release the same amount of energy
3. Current will increase
Explanation:
In Ohm's law the equation for current is current = voltage / resistance.
In order to explain how current is effected when resistance decreases while voltage stays the same, lets represents the situations with some possible inputs.
Let's compare 3 different closed circuits all with a voltage of 10V.
In circuit 1, the resistance is 5 ohm.
In circuit 2, the resistance is 2 ohms.
In circuit 3, the resistance is 1 ohms.
The current of:
Circuit 1 = Voltage / Resistance = 10 V / 5 ohms = 2 Amps
Circuit 2 = Voltage / Resistance = 10V / 2 ohms = 5 Amps
Circuit 3 = Voltage / Resistance = 10V / 1ohm = 10 Amps
As you can see in this representation, as the resistance in a circuit increases while the voltage is constant, the total current is increased.
4. The resistance of a conductor is the ratio of the voltage
between its ends to the current through it.
If the voltage between the ends of a light bulb's filament
increases but the filament's resistance remains constant,
then the current through it increases by the same factor
as the voltage increase. The effect is to cause the light
to emit more light and heat ... both increase proportional
to the square of the voltage ... and possibly to "burn out".
Part 2
1. it's a circuit wherein all the elements are in parallel and a resistance is fitted in series across which a voltmeter is connected to measure potential drop acrossR so as to find the current across the load that is bulb which connected to in series with the resistor
2. A resistor is a passive two-terminal electrical component that implements electrical resistance as a circuit element. In electronic circuits, resistors are used to reduce current flow, adjust signal levels, to divide voltages, bias active elements, and terminate transmission lines, among other uses.
3. The switch simply opens (off) or closes (on) the connection between the two terminals on the switch. When the switch is on, current flows along the black wire through the switch to the light, and then returns to ground through the white wire to complete the circuit.
4. the current runs through the motherboard and into the smaller components or the small internal wiring
5. A battery is made up of three parts. The Cathode (positive end +) , the Anode (negative end -) and the electrolyte. The electrolyte allows electrical charges to travel between the cathode and anode. This chemical reactions creates the flow of electricity supplying the electrical voltage potential to power a circuit.
Typical materials of a battery are as follows
- Anode most often is made of zinc
- Manganese dioxide acting as Cathode.
- the electrolyte between and inside contains ions

Hi! I need help with some math questions. Not problems though, I’ll show what I mean.
It says, “Why do you think it is important to include negative numbers in our number system?”, and, “What is special about zero (0)?”
Would appreciate it if you helped!
Answer:
Negative numbers are most important especially in the field of physics and chemistry. They help us in real life geometry and in almost everything. The discovery of the number system has changed the human civilization to such a great extent, that, without it, we can't even think of architectures and the nature's law(by calculus).
Dominantly, zero is the most ever used number and is very important to express anything.
Without it, you couldn't have the digital world (simply, no computers, no phones, no machines and no A.I.).
As we all know, Dr. Aryabhatta, the legendary guy, who made the no. '0', holds the credits!
I hope it will be useful.

Jesse drank 3/4
liter of water Monday before going jogging. He drank 3/5
liter of water after his jog. How much water did Jesse drink altogether? Write your answer as a mixed number.
Answer:
1 7/20
Step-by-step explanation:
You want to add 3/4+3/5, but they need to have the same denominator. A common factor for 4 and 5 is twenty, so multiply 3/4 by 5/5 and 3/5 by 4/4. This will give you 15/20 + 12/20. You can add this to get 27/20, or 1 7/20 as a mixed number
