Answer:
b = 3 in
Step-by-step explanation:
The area (A) of a rectangle is
A = lb ( l is the length and b the breadth )
Here A = 24, l = 4 and breadth = b + 3 , thus
4(b + 3) = 24 ( divide both sides by 4 )
b + 3 = 6 ( subtract 3 from both sides )
b = 3
Thus the width of the message is 3 in

The number of days each licensed driver in Marion County uses a commuter rail line annually is normally distributed with mean 66 and standard deviation 21. How many days must a driver use a commuter rail line annually to be in the top 5% of rail users? Round to the nearest integer.
Answer:
31.5 days
Step-by-step explanation:
We.solve using z score formula
z-score is is z = (x-μ)/σ,
where x is the raw score
μ is the population mean
σ is the population standard deviation.
The 5th percentile z score = -1.645
Mean = 66
Standard deviation = 21
Hence:
-1.645 = x - 66/21
-1.645 × 21 = x - 66
-34.545 = x - 66
-34.545 + 66 = x
x = 31.455 days
Approximately to the nearest round integer
= 31.5 days
Therefore, driver use a commuter rail line 31.5 days annually to be in the top 5% of rail users

Which steps can be used in order to determine the solution to Negative 1.3 + 4.6 x = 0.3 + 4 x? Subtract 1.3 from both sides of the equation, add 4x to both sides of the equation, then divide by the coefficient of x. Subtract 1.3 from both sides of the equation, subtract 4.6x from both sides of the equation, then divide both sides by the coefficient of x. Add 1.3 to both sides of the equation, subtract 4.6x from both sides of the equation, then divide both sides by the coefficient of x. Add 1.3 to both sides of the equation, subtract 4x from both sides of the equation, then divide both sides by the coefficient of x.
Answer:
its D
Step-by-step explanation:
got it correct on a test :)
The correct option is Option D: Adding 1.3 to both sides of the equation, subtracting 4x from both sides of the equation, then dividing both sides by the coefficient of x.
What is the linear equation?The linear equation is an equation where the highest degree of the variables used in the equation is 1.
For example 9x+5=23
Given the equation is -1.3 +4.6x= 0.3+ 4x
In order to the linear equation first, try to keep the constant and the variable part to one side by adding or subtracting the constant term.
Then divide the coefficient of the variable (if the coefficient is not equal to 1) on both sides.
Here the given equation is -1.3 +4.6x= 0.3+ 4x
Step-1: Adding 1.3 to both sides of the equation
⇒-1.3 +4.6x +1.3 = 0.3+ 4x +1.3
⇒4.6x = 4x+1.6
Step-2: subtracting 4x from both sides of the equation
⇒4.6x -4x = 4x+1.6-4x
⇒ 0.6x=1.6
Step-3: dividing both sides by the coefficient of x i.e. 0.6.
⇒0.6x/0.6 = 1.6/0.6
⇒x= 2.67
Therefore the correct option is Option D: Adding 1.3 to both sides of the equation, subtracting 4x from both sides of the equation, then dividing both sides by the coefficient of x.

Answer:
I think A
Step-by-step explanation:
Because if you change it from (43 + 60) + 40 to (60 + 40) + 43 = 143
You automatically know it is 143 because 60 + 40 is 100 + 43 = 143
And it wouldn't be D because that is already in a easy way the solve. The others looked to complicated to even attempt so it has to be A.

it costs $24,893.75 to repay a loan of 17,500 at 6.5% annual interest. How many years does it take to repay the loan? I saw somebody asked this question, but the answer wasn't specific.
Answer:
11.5 years
Step-by-step explanation:
The formula for the monthly payment of a loan is:
[tex] A = P\dfrac{r(1 + r)^n}{(1 + r)^n - 1} [/tex]
where
A = monthly payment
r = interest rate per period
n = number of periods
Assuming a monthly payment, we have
P = 17500
r = 0.065/12
The total amount of payments is the monthly payment times the number of payments, so
An = 24893.75
We can try 10 years. n = 10 * 12 = 120
[tex] A = 17500\dfrac{\frac{0.065}{12}(1 + \frac{0.065}{12})^{120}}{(1 + \frac{0.065}{12})^{120} - 1} = 198.71 [/tex]
An = 198.71 * 120 = 23845.08
The total amount of payments is too low.
Let's try 11 years.
n = 11 * 12 = 132
[tex] A = 17500\dfrac{\frac{0.065}{12}(1 + \frac{0.065}{12})^{132}}{(1 + \frac{0.065}{12})^{132} - 1} = 185.92 [/tex]
An = 185.92 * 132 = 24540.90
The total amount of payments is still too low.
Let's try 12 years.
n = 12 * 12 = 144
[tex] A = 17500\dfrac{\frac{0.065}{12}(1 + \frac{0.065}{12})^{144}}{(1 + \frac{0.065}{12})^{144} - 1} = 175.34 [/tex]
An = 185.92 * 144 = 25248.41
The total amount of payments is too high.
11 years is too little, and 12 years is too much.
Let's try 11.5 years.
n = 11.5 * 12 = 138
[tex] A = 17500\dfrac{\frac{0.065}{12}(1 + \frac{0.065}{12})^{138}}{(1 + \frac{0.065}{12})^{138} - 1} = 180.39 [/tex]
An = 180.39 * 138 = 24893.20
11.5 gives a total of payments of $24,893.20 which is very close to $23.893.75.
Answer: 11.5 years
The total amount of payments is too high.

Answer:
x=7.5
Total area = 27+15 = 42
Step-by-step explanation:
For question 13, we still need to find the bottom side of the T-shape that's not labeled. That's just 9-3.5-3.5=9-7=2.
Now that we know all the side lengths, we can set up an equation where all the side lengths add up to 39, and solve for x:
9+3+3+3.5+3.5+x+x+2=39
24+2x=39
2x=15
x=7.5
For question 14, we can divide the shape into 2 rectangles, which is shown in the picture attaches. Then, we just solve for each rectangle's area separately, and then add them up.
Rectangle A = 9*3=27
Rectangle B = 7.5*2=15
Total area = 27+15 = 42

Which of the following is a true statement?
4/5 x 4/5=1
3/10 ÷ 7/9=3/10 x 9/7
9/12 x 12/9= 0
1/2 ÷1/2= 1/4
Answer:
3/10 ÷ 7/9=3/10 x 9/7 is the true one
Step-by-step explanation:
4/5 x 4/5 = 16/25 not 1 so this statement is wrong.
3/10 ÷ 7/9=3/10 x 9/7, this is the true statement and it equals 27/70
9/12 x 12/9= 1 not 0
1/2 ÷1/2= 1 not 1/4

an ant has fallen into a bottle 60cm deep and is climbing up 8 cm everyday. As it is exhausted, the ant is slipping down 4cm every night. Then how long would it take teh ant to escape from the bottle
Answer:
It took 13 days and a half to escape
Step-by-step explanation:
This is a classic problem where the first answer that comes to one's mind is not the correct answer.
The ant climbs up 8 cm per day and slips down 4 cm every night. It means the real distance the ant goes up is 8 - 4 = 4 cm per day. Since the total distance is 60 cm, it could lead us to think the time needed to escape from the bottle is 60/4=15 days. This is wrong, as we'll prove below.
Assume the last day, the ant climbs up the final 8 cm and escapes. We don't know yet when, but we can assure that day the ant was at a height of 60 - 8 = 52 cm.
That 52 cm was the result of the 4 cm per day the ant effectively went up, thus it needed 52/4=13 days to reach that height.
At 13 days, the ant was at 52 cm, the day 14 it climbed up the final 8 cm and escaped.
Answer: It took 13 days and a half to escape
