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.
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.
I don't know the answer lol

The Girls Who Code Club is selling T-shirts for $12.50 each. They want to raise at least $1000 and so far have collected $337.50. Which inequality below could be used to find the minimum number of T-shirts they will need to sell to reach their goal?
Answer:
650
Step-by-step explanation:
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.
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
find the interest rate

Answer:
The first and 3rd are functions, but the second and fourth are not functions.
Step-by-step explanation:
To see if something is a function, use the vertical line test. If there are multiple y coordinates for a singular point for x, it is not a function.
given triangle ABC is congruent to triangle XYZ, determine the value of n
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.

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.
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.

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".

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
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".
