Suppose that the battery has a total current in a series connection of 12.0 Ω and the lamps resistances R₁, R₂ and R₃ are 6.0 Ω, 4.0 Ω and 2.0 Ω, respectively. Compute for (a) the total resistance in a series connection and (b) the voltage drops across each resistor.

Answers

Answer:

Step-by-step explanation:

Let the total current = 12A

If there are there lamps 6.0 Ω, 4.0 Ω and 2.0 Ω in series,

a) The total resistance in series connected circuit will be:

Rt = R₁+R₂+R₃

Rt = 6+4+2

Rt = 12Ω

b) According to ohm's law, the voltage drop is expressed as V = IR

I is the current in each lamps

Note that the same current flows in the resistors for series connection

R are the resistances

For the 6Ω, resistor

V = IR

V = 12(6)

V = 72V

The voltage drop across it is 72V

For the 4Ω, resistor

V = IR

V = 12(4)

V = 48V

The voltage drop across it is 48V

For the 2Ω, resistor

V = IR

V = 12(2)

V = 24V

The voltage drop across it is 24V

given triangle ABC is congruent to triangle XYZ, determine the value of n

Answers

Since the triangles are congruent their sides are equal. Here, XY = AB
5n+8 = 38
n = 6

The value of n in the given congruent triangle is 6.

What are congruent triangles?

Congruent triangles have the same corresponding angle measures and side lengths.

Given that two congruent triangles, Δ ABC ≅ Δ XYZ,

Since, we know that, corresponding parts of congruent triangle are equal,

Therefore,

AB = XY

5n+8 = 38

5n = 30

n = 6

Hence, the value of n in the given congruent triangle is 6.

Janet enjoys reading books, and reads an average of 4 books a month. Janet's younger brother, Alex waited for a month before deciding he liked reading, and also reads at an average of 4 books a month. If m represents the number of months Janet has been reading books, the equation 4m=4(m−1) represents the situation where Alex and Janet have read the same number of books.

Solve the equation to find the number of months it will take for Alex and Janet to have read the same number of books. Show your work.

Answers

Answer:

No solution

Step-by-step explanation:

4m = 4(m - 1)

Distribute;

4m = 4m - 4

Subtract 4m from both sides;

0 ≠ -4

No months because Alex cannot catch up to Janet since they both read the same amount of books per month.

Answer: They will never have read the same number of books

Step-by-step explanation:

4(m-1) will always be less than 4m no matter what.

Jadiel wants to take his buddies out for pizza. Each medium
pepperoni pizza costs $10, and he has only $23 in his pocket. How
much money would he have to borrow to order three medium
pepperoni pizzas?

Answers

Answer:

7$

Step-by-step explanation:

1) 3x10=30 so 30 is how much money he needs

2)30-23=7 so 7 is how much he needs to borrow

Answer:

$7

Step-by-step explanation:

The reason is because three medium pepperoni pizzas cost $30, because you have to multiply $10x3 since each pizza cost $10. He already has $23 dollars in his pocket. You have to subtract his total value which is $23 from $30 to get $7.

Theoretically, the standard error of the mean decreases as the sample size increases measures the variability of the sample mean from sample to sample is never larger than the standard deviation of the population All of the Above

Answers

Answer: All of the above

Step-by-step explanation:

The formula for the standard error of the mean is:

σM =σ/√N

where,

σM = standard error of the mean

σ = standard deviation of sample

√N = square of sample size

As the sample size of a population rises, it should be noted that the standard error of the mean will decrease. This is due to the fact that when there's an increase in sample size, there'll be cluster of the sample mean around the population mean.

Also, the the standard error of the mean measures the variability of the sample mean from sample to sample and is never larger than the standard deviation of the population.

Therefore, the answer will be "all or the above".

Answers

Apply pythagorus theorem and check whether it’s right or wrong
A^2 + B^2=C^2
Put the largest number in C and others in A and B

The Pythagoras theorem is not applicable in 24, 22, and 40 thus (D) will be not the side of the right angle triangle.

What is a triangle?

A triangle is a 3-sided shape that is occasionally referred to as a triangle. There are three sides and three angles in every triangle, some of which may be the same.

There are many types of triangles such that right-angle triangles, equilateral triangles, and much more.

The Pythagoras theorem is given as,

Hyp² = base² + perp²

Since the hyp is the biggest side thus it can be said to be as,

Biggest side² = (smaller side 1)² + (smaller side 2)²

In the  24, 22 and 40,

40² ≠ 22² + 24² thus it will not right an angle triangle,

Hence "In 24, 22, and 40, the Pythagorean theorem is not applicable so it will be not a right angle triangle".

An insurance company only pays for full replacement if a driver is in a
wreck and is traveling a speed not deemed to be reckless. A speed of 80
mph or greater is considered reckless. Mallory has an accident and has
filed an insurance claim. The insurance uses a standard constant of
proportionality of .05 and she has a stopping distance of 245 feet. Will her
insurance provide a full replacement of her car? Explain why or why not
and show all work.

Answers

Answer:

70 mph, Yes the insurance company Will provide a full replacement for her car.

Step-by-step explanation:

To get the equation lets use direct variation, and K for the constant, S for the speed, and D for the stopping distance. d=ks^2, find s, or the speed, which will get the equation s=√d/k. The speed s, is equal to the square root of the stopping distance divided by the constant. Next, lets plug in the numbers s=√245/.05. Then, we find the square root of each number, √245 = ~15.652, and √.05 ~.2236  s=15.652/.2236 then divide, which will equal s=70. 70<80, so the insurance company will provide a full replacement for her car.
