Ahamd wants to cover a box that is 6 cm long 4 cm high and 4 cm wide with material on all the sides how much material does he need
Answer:
56cm²
Explanation:
the amount of material he needs would be the total surface area of the box. surface area can be calculated by finding the sum of surface area of all the sides of the box. since the opposite sides are equal, we can find the surface area of 3 different sides and then multiply it by 2.
(4 + 4) + (4 + 6) + (6 + 4) × 2
= 8 + 10 + 10 × 2
= 28 × 2
= 56cm²

John needs to divide the sample in half once the number of bacteria has reached 1000. How many hours after the initial time must be divide the sample?
Answer:
Option A
Step-by-step explanation:
The complete question is attached here
The rate of increase of bacterial population be K
As we know
[tex]Y = Y_0 * e^{kT}[/tex]
where Y is the final population. In this case it is 1000
K is the rate of increase of population i.e 3 times per hour
T is the time in hours
Y0 is the initial population = 5
Substituting the given values, we get -
[tex]1000 = 5 *e^{3*T}\\200 = e^{3*T}[/tex]
Taking log on both sides, we get -
ln [tex]200[/tex] = ln [tex]e^{3T}[/tex]
[tex]2.718 * 2.301 = 3T[/tex]
T = 2.084 hours
hence, option A is correct
The number of hours required after the initial time must be divide the sample by John is 2.084 hours.
What is an exponential function?Exponential function is the function in which the function growth or decay with the power of the independent variable. The curve of the exponential function depends on the value of its variable.
The exponential function with dependent variable y and independent variable x can be written as,
[tex]y=ba^x+c[/tex]
Here, a, b, and c are the real number
John needs to divide the sample in half once the number of bacteria has reached 1000.
The table of this bacterial growth is,
Time(hours) Number of bacteria
0 5
1 15
2 45
The rate of increasing the bacteria each hour is,
[tex]x=\dfrac{15}{5}=3\\x=\dfrac{45}{15}=3[/tex]
Thus, the exponential rate is 3.
Now the number of reached is 1000, and the initial population was 5. Therefore, for the time t, the exponential function can be given as,
[tex]1000=5e^{3t}\\\dfrac{1000}{5}=e^{3y}\\200=e^{3y}[/tex]
Taking log both the sides as,
[tex]\ln (200)=\ln e^{3t}\\2.301=0.434({3t})\\t=2.084[/tex]
Hence, the number of hours required after the initial time must be divide the sample by John is 2.084 hours.

6) On Saturday afternoon tickets
for a popular band were put on sale
on the internet. There are 900
tickets and every hour about 75
tickets are sold. How long will it
take for there to be only 150 tickets
left?
Answer:
It will take 10 hours
Step-by-step explanation:
first you subtract 150 from 900 (900-150) to get 750. next you divide 750 by 75 since that is the rate the tickets are being sold (750÷75) which would equal to 10.

What is the approximate area of the shaded sector ?
Answer:
7.5 cm²
Step-by-step explanation:
Area of shaded sector = θ/360 × πr²
Where,
θ = 180° - 84° = 96°
r = ½(6) = 3 cm
Area of shaded sector = 96/360 × π × 3²
Area = 7.53982238 ≈ 7.5 cm²
In a particular year, a total of 50,127 students studied in two of the most popular host countries when traveling abroad. If 8383 more students studied in the most
popular host country than in the second most popular host country, find how many students studied abroad in each country.
There were students who studied abroad in the most popular host country.
Answer:
In the most popular abroad country: 29,255 students
In the second-most one: 20,872 students
Step-by-step explanation:
Let's write the situation in an equation to help us solve this. X represents the amount of students in the second most popular country. So we know that in total, there's 50,127 students so let's make an equation that equals this. ???????=50,127. As we know, the most popular country has 8383 more students than the second one so we can write it as x+8383 and for the second most popular country, we can write it as x. We know that both of the countries students combined equal 50,127 students so we have our equation. (x)+(x+8383)=50,127 students. After solving the equation, you get x=20, 872. As we know x=the amount of students in the second most popular country which means there's 20,872 students in the second one. Additionally, for the first most popular one, the equation for the amount of students in it is x+8383 so..... 20,872+8383=Total number of students in the most popular one which is 29,255 students.

In ARST, the measure of ZT=90°, the measure of ZR=39°, and TR = 55 feet. Find the
length of ST to the nearest tenth of a foot.
Answer:
44.5 ft
Step-by-step explanation:
Reference angle = 39°
Opposite = x
Adjacent = 55
Apply trigonometric function TOA:
Tan 39 = Opp/Adj
Tan 39 = x/55
55 × Tan 39 = x
44.5381218 = x
x ≈ 44.5 ft
A random sample of 41 cars in the drive-thru of a popular fast food restaurant revealed an average bill of $19.55 per car. The population standard deviation is $6.33. Estimate the mean bill for all cars from the drive-thru with 97% confidence.
Answer:
[tex]19.55\pm2.145[/tex]
Step-by-step explanation:
We use the equation [tex]\bar x\pm z^*\sigma/\sqrt n[/tex], where [tex]\bar x=19.55[/tex], [tex]\sigma=6.33[/tex], [tex]n=41[/tex], and [tex]z^*=2.17[/tex]. We obtain [tex]z^*[/tex] from the z-score of a 0.97 confidence level.
The 97% confidence interval estimate for the mean bill for all cars from the drive-thru is approximately $17.23 to $21.87.
To estimate the mean bill for all cars from the drive-thru with 97% confidence, we can use a confidence interval.
Sample size (n) = 41
Sample mean (x(bar)) = $19.55
Population standard deviation (σ) = $6.33
To calculate the confidence interval, we'll use the formula:
Confidence Interval = Sample Mean ± (Critical Value * Standard Error)
First, we need to calculate the standard error, which is the standard deviation of the sample mean.
Standard Error (SE) = Population Standard Deviation / √(Sample Size)
SE = $6.33 / √(41)
Next, we determine the critical value based on the desired confidence level. Since we want a 97% confidence interval, we need to find the critical value corresponding to a 97% confidence level.
The critical value can be obtained from a standard normal distribution table or by using a calculator. For a 97% confidence level, the critical value is approximately 2.17.
Now, we can calculate the confidence interval:
Confidence Interval = $19.55 ± (2.17 * SE)
Substituting the values:
Confidence Interval = $19.55 ± (2.17 * ($6.33 / √41))
Calculating this, we find:
Confidence Interval ≈ $19.55 ± $2.32
Therefore, the 97% confidence interval estimate for the mean bill for all cars from the drive-thru is approximately $17.23 to $21.87.

The first error occurs in step____ .
The value of 3−(5−32+4)+62·(−2) is ____.
Answer:
The first error occurs in Step 3
The value of the equation is -69
Step-by-step explanation:
The error is that 3-0+(-72) is actually supposed to be 3-0-72 because once you multiply the positive 36 and the negative 2, the equation automatically becomes negative.
A tool box has the dimensions of 9 in by 5 in by 6 in. If Kimberly plans to double one dimension to build a larger tool box, she believes she would double the volume of the tool box. Is she correct?
Answer:
She is correct.
Step-by-step explanation:
First, multiply 9 * 5 * 6 (original)
9 * 5 * 6
45 * 6
270 in³
Next, multiply 18 * 5 * 6 (if the length was doubled)
18 * 5 * 6
90 * 6
540 in³
Now divide 540 by 270.
540/270
2
Since the volume doubled, Kimberly is correct.
(You could do this for the other two and Kimberly is still correct.
If width was doubled
9 * (5 * 2) * 6 = 9 * 10 * 6
9 * 10 * 6 = 90 * 6
540
If height was doubled
9 * 5 * (6 * 2) = 9 * 5 * 12
45 * 12
540
540/270
