Answer:
There will be one person on 1 square yard of land after 1,892,147.588 years.
Step-by-step explanation:
Continuous exponential growth formula:
[tex]P(t)=Pe^{rt}[/tex]
P(t)= Population after t years.
P= Initial population
r=rate of growth.
t= time in year
Given that,
Growth rate of country A (r)= 4.9% per year=0.049 per year.
Initial population (P)= 151,000.
Land area of country area= 14,000,000,000 square yards.
There will be one person on one square yard of land.
So, there will be 14,000,000,000 person for 14,000,000,000 square yard of land in country A.
P(t)=14,000,000,000 person
[tex]\therefore 14,000,000,000= 151,000 e^{0.049t}[/tex]
[tex]\Rightarrow e^{0.049t}=\frac{ 14,000,000,000}{ 151,000}[/tex]
Taking ln both sides
[tex]\Rightarrow ln|e^{0.049t}|=ln|\frac{ 14,000,000,000}{ 151,000}|[/tex]
[tex]\Rightarrow {0.049t}=ln|\frac{ 14,000,000,000}{ 151,000}|[/tex]
[tex]\Rightarrow t}=\frac{ln|\frac{ 14,000,000,000}{ 151,000}|}{0.049}[/tex]
[tex]\Rightarrow t}=1,892,147.588[/tex] years
There will be one person for every square yard of land after 1,892,147.588 years.
Which one is bigger 2.300 mg or 2 g
Answer:
2 grams is bigger than 2.300 mg.
Step-by-step explanation:
1 milligram is equal to 0.001 gram.
1 gram is equal to 1000 milligrams.
If this helped you, Brainliest is appreciated.
Answer:
2 grams is bigger
Step-by-step explanation:
Two grams is bigger than 2.3 milligram . This is because 1 gram is equivalent to 1000 milligrams. To work that out you would multiply 2 by 1000, which is 2000
1 gram=1000 milligram
1) Multiply 2 by 1000.
[tex]1000*2=2000 mg[/tex]
However if it was a misplaced decimal and it was meant to be 2300 milligrams, then 2300 milligrams would be bigger.

How many zoos have exactly

1717 sloths?
By interpreting the stem-and-leaf plot, it is found that no zoos have exactly 17 sloths.
Explanation:In the stem-and-leaf plot, we locate the stem which corresponds to the number '1', and then we check the corresponding leaves. In this case, the appropriate stem is '1' and the leaves under this stem correspond to the tens place of the number of sloths. So, now we check the leaf '7' under stem '1'. Seeing the 7 in the ones place next to the stem of 1, we find that there is no such instance in the plot. Therefore, we can conclude that no zoos have exactly 17 sloths.

The admission fee at an amusement park is $1.50 for children and $4.00 for adults. On a certain day, 2,000 people entered the park, and the admission fees that were collected totaled $4,750. How many children and how many adults were admitted
Answer:
In that day 1300 children and 700 adults were admitted.
Step-by-step explanation:
Since the people who enter the park are either adults or children, the sum of these two types of people must be equal to the total amount that entered the park. So we have:
children + adults = 2000
The total amount collected must be the sum of the people that entered the park multiplied by the ticket fee for each type. We have:
1.5*children + 4*adults = 4750
We now have two equations and two variables so we can solve the system.
children + adults = 2000 equation 1
1.5*children + 4*adults = 4750 equation 2
We can multiply the equation 1 by -1.5 and sum it with the equation 2 to solve for adults, we have:
-1.5*children - 1.5*adults = -3500
1.5*children + 4*adults = 4750
2.5*adults = 1750
adults = 1750/2.5 = 700
To solve for children we apply the found value for adults on the equation 1.
children + 700 = 2000
children = 2000 - 700 = 1300
In that day 1300 children and 700 adults were admitted.
Answer:
700 adults and 1300 children
Step-by-step explanation:
Let 'C' represent number of children
'A' represent number of adults
->If 2,000 people entered the park, the equation will be
C+A=2000
C=2000-A ->eq(1)
->$1.50 for children and $4.00 for adults.
$1.50C+$4.00A=$4,750
Substituting for C from above.
$1.50(2000-A)+$4.00A= $4,750
$3000-$1.50A+$4.00A=$4,750
$2.50A = $4,750 - $3000
$2.50A=$1750
A= 700
and for children:
eq(1)=>
C=2000-700
C= 1300
Thus, 700 adults and 1300 children were admitted.

cos30° = [tex]\frac{\sqrt{3} }{2}[/tex] and tan30° = [tex]\frac{1}{\sqrt{3} }[/tex] , then
cos30° = [tex]\frac{adjacent}{hypotenuse}[/tex] = [tex]\frac{6}{m}[/tex] = [tex]\frac{\sqrt{3} }{2}[/tex] ( cross- multiply )
[tex]\sqrt{3}[/tex] × m = 12 ( divide both sides by [tex]\sqrt{3}[/tex] )
m = [tex]\frac{12}{\sqrt{3} }[/tex] ← rationalise by multiplying numerator/ denominator by [tex]\sqrt{3}[/tex] )
m = [tex]\frac{12}{\sqrt{3} }[/tex] × [tex]\frac{\sqrt{3} }{\sqrt{3} }[/tex] = [tex]\frac{12\sqrt{3} }{3}[/tex] = 4[tex]\sqrt{3}[/tex]

The population of a small town is given by the function p=35t+1450,where t is the number of years since 2015. What would the town's population be in 2020
Hi there! Hopefully this helps!
--------------------------------------------------------------------------------------------------------------
Answer: The population is 1,625.
So the equation is:
p = 35t + 1,450.
t = the number of years since 2015.
2020 - 2015 = 5.
So now we are in 2020, which is 5 years ahead from 2015.
So: t = 5.
Now we need to rewrite the equation, then evaluate.
35(5) + 1,450 =
175 + 1,450 =
1,625If an object is projected upward from ground level with an initial velocity of 96 ft per sec, then its height in feet after t seconds is given by s(t)equalsminus16tsquaredplus96t. Find the number of seconds it will take to reach its maximum height. What is this maximum height?
Answer:
Number of seconds to reach maximum height = 3 seconds
Maximum height = 144 ft
Step-by-step explanation:
We are given that;
s(t) = -16t² + 96t
Now, s(t) is a function whose graph is an upside-down parabola, so the maximum s value occurs at the vertex.
Thus, the applicable formula for coordinate of vertex is t = -b/(2a) where a is the coefficient -16 and b is 96
Thus,t = -96/(2 x - 16)
t = 96/32
t = 3
Thus maximum height will be at 3 seconds.
Thus;
Max height = s(3) = -16(3)² + 96(3)
Max height = -144 + 288 = 144 ft
The object will reach its maximum height of 144 feet in 3 seconds.
Given information:
An object is projected upward from ground level with an initial velocity of 96 ft per sec.
The height in feet after t seconds is given by [tex]s(t)=-16t^2+96t[/tex].
Now, it is required to find the time at which the object will reach its maximum height.
The object will reach maximum height when velocity of the object becomes zero.
So, the velocity of the object can be written as,
[tex]s(t)=-16t^2+96t\\v(t)=\dfrac{d(s(t))}{dt}=-32t+96[/tex]
So, the time at maximum height can be calculated as,
[tex]v(t)=-32t+96=0\\t=3[/tex]
So, after 3 seconds the object will reach its maximum height.
Now, the maximum height of the object will be,
[tex]s(t)=-16t^2+96t\\s(3)=-16\times 3^2+96\times 3\\s(3)=144\rm \; ft[/tex]
Therefore, the object will reach its maximum height of 144 feet in 3 seconds.

People use water to cook, clean, and drink every day. An estimate of 26.5% of the water used each day is for cleaning. If a family uses 68.9 gallons of water a day for cleaning, how many gallons do they use every day?
Final answer:
To find the total daily water usage of the family, divide the amount of water they use for cleaning, 68.9 gallons, by the percentage of their total usage that goes to cleaning, which is 26.5%. The result is that the family uses about 260 gallons of water every day.
Explanation:
To calculate how many gallons of water the family uses every day, we need to establish the total daily water usage based on the percentage used for cleaning.
Since we know that 26.5% of their total water usage is allocated for cleaning, and they use 68.9 gallons for this purpose, we can find the total daily usage with a simple division:
Total daily water usage = Water used for cleaning / Percentage used for cleaning Total daily water usage = 68.9 gallons / 0.265 Total daily water usage = 260 gallons (rounded to the nearest whole number)
Thus, the family uses approximately 260 gallons of water per day for all their needs, including cooking, cleaning, and drinking.
Final answer:
To find out how many gallons a family uses every day, set up a proportion to find the total amount of water used for cleaning and solve for x. The family uses approximately 259.62 gallons of water every day.
Explanation:
To find out how many gallons a family uses every day, we need to determine the total amount of water used for cleaning. The question states that 26.5% of the water used each day is for cleaning, and the family uses 68.9 gallons for cleaning. We can set up a proportion to find the total amount of water used:
26.5% / 100% = 68.9 / x
Now we can solve for x by cross multiplying:
26.5x = 68.9 * 100
Dividing both sides of the equation by 26.5, we find that x is approximately 259.62.
Therefore, the family uses approximately 259.62 gallons of water every day.

You ride your bicycle 40 meters. How many complete revolutions does the front wheel make?
The front wheel of the bicycle makes approximately 18 complete revolutions.
Explanation:To find the number of complete revolutions the front wheel makes, we need to know the circumference of the wheel. Let's assume the diameter of the wheel is 0.7 meters. The circumference of the wheel can be calculated using the formula C = πd, where C is the circumference and d is the diameter. Substituting the given values, C = 3.14 * 0.7 = 2.198 meters.
Since the bicycle travels 40 meters, we can divide the distance traveled by the circumference of the wheel to find the number of complete revolutions. 40 / 2.198 = 18.19.
So, the front wheel of the bicycle makes approximately 18 complete revolutions.

And rounded up we have that n=649
b) [tex]n=\frac{0.5(1-0.5)}{(\frac{0.05}{2.58})^2}=665.64[/tex]

A confidence interval is "a range of values that’s likely to include a population value with a certain degree of confidence. It is often expressed a % whereby a population means lies between an upper and lower interval".
The margin of error is the range of values below and above the sample statistic in a confidence interval.
Normal distribution, is a "probability distribution that is symmetric about the mean, showing that data near the mean are more frequent in occurrence than data far from the mean".
Solution to the problem
In order to find the critical value we need to take in count that we are finding the interval for a proportion, so on this case we need to use the z distribution. Since our interval is at 99% of confidence, our significance level would be given by [tex]\alpha=1-0.99=0.01[/tex] and [tex]\alpha/2 =0.005[/tex]. And the critical value would be given by:
[tex]z_{\alpha/2}=-2.58, z_{1-\alpha/2}=2.58[/tex]
Part a
The margin of error for the proportion interval is given by this formula:
[tex] ME=z_{\alpha/2}\sqrt{\frac{\hat p (1-\hat p)}{n}}[/tex] (a)
And on this case we have that [tex]ME =\pm 0.05[/tex] and we are interested in order to find the value of n, if we solve n from equation (a) we got:
[tex]n=\frac{\hat p (1-\hat p)}{(\frac{ME}{z})^2}[/tex] (b)
And replacing into equation (b) the values from part a we got:
[tex]n=\frac{0.58(1-0.58)}{(\frac{0.05}{2.58})^2}=648.600[/tex]
And rounded up we have that n=649
Part b
For this case we can use an estimator for p as [tex]\hat p=0.5[/tex]
[tex]n=\frac{0.5(1-0.5)}{(\frac{0.05}{2.58})^2}=665.64[/tex]

A thanksgiving day promotion included $1 mail-in rebate for the purchase of a turkey wing at least 20 lb. Esther Robert purchased a 22-pound turkey for $1 and seventy-nine a pound. What did it cost for after rebate if an envelope cost $0.15 and a stamp cost $0.39?
Answer:
$38.92
Step-by-step explanation:
In this question, we are calculating the amount it would cost purchasing a turkey wing after giving some rebate.
Firstly, we calculate the cost of purchasing 22 pounds turkey
That would be 22 * $1.79 = $39.38
Now we subtract the cost of the rebate ;
That would be $39.38 -$1 = $38.38
Now, we add the envelope cost and the stamp cost
That would be $38.38 + $0.39 + $0.15 = $38.92
The final cost of the 22-pound turkey after accounting for the price per pound, mail-in rebate, and the costs of an envelope and stamp is $38.92.
Explanation:The cost of a 22-pound turkey at $1.79 per pound is calculated first, then subtract the $1 mail-in rebate, and finally add the costs of the envelope and the stamp required for the rebate.
First, find the total cost of the turkey without the rebate:
22 pounds × $1.79 per pound = $39.38Next, add the cost of the envelope and stamp:
Envelope: $0.15Stamp: $0.39Total for envelope and stamp: $0.15 + $0.39 = $0.54After receiving the rebate of $1, the final cost is calculated:
Total cost before rebate: $39.38Total cost for envelope and stamp: $0.54Cost after rebate: ($39.38 + $0.54) - $1 = $38.92Therefore, the final cost of the turkey after the rebate is $38.92.

A grocery store clerk put only packages of purple grapes and packages of green grapes on a shelf. The ratio of the number of packages of green grapes to the total number of packages on the shelf was 9 to 14. Which number could be the number of packages of purple grapes the clerk put on the shelf?
Answer:
The answer is 5, 10, 15, 20 or any positive multiples of 5
Step-by-step explanation:
Since the ratio of green grapes to the total number of grapes is 9:14 and there are only purple and green grapes on the shelf. It implies the total number of purple grapes to overall grapes is 5:14.
Since this ratio is already at it's lowest form, it implies the possible number of purple grapes are 5, 10, 15, 20 or any positive multiple of 5.

The original triangle has sides of lengths 15 inches (longest side), 8 inches (shortest side), and 10 inches. Given that the longest side of the new triangle is 9 inches, we can find the scale factor by dividing the new longest side by the original longest side: 9 inches / 15 inches = 3/5.
Now, we use this scale factor to find the length of the shortest side in the new triangle: 8 inches (original shortest side) x 3/5 (scale factor) = 4.8 inches.
Therefore, the length of the shortest side of the new triangle is 4.8 inches.

Step-by-step explanation:
| 1 4 -1 | | 2 -1 |
| 3 2 2 | | 0 3 | Product = 2 x 3 and 3 x 2 = 2 x 2
| 5 2 | It is possible to do this product,
the result will be a 2 x 2 matrix
Process
1.- Multiply first row by first column and second row by second column.
2.- Multiply the second row by the first column and second row by the second column.
= (1 x 2) + (4 x 0) + (-1 x 5) = 2 + 0 - 5 = -3
= (1 x -1) + (4 x 3) + (-1 x 2) = -1 + 12 - 2 = 9
= (3 x 2) + (2 x 0) + (2 x 5) = 6 + 0 + 10 = 16
= (3 x -1) + (2 x 3) + (2 x 2) = -3 + 6 + 4 = 7
Result

Answer:
Step-by-step explanation:
the answers for "in e^3" is 3
"in e^2y" is 2y
"e^in 1" is 1
"e^in 5x" is 5x
Answer: 3, 2y, 1, 5x.
We have to simplify the given expressions.
We use the formula: [tex]ln(e^a)=a[/tex].
So, [tex]ln(e^3)=3[/tex], here a = 3.
[tex]lne^{2y}=2y[/tex], here a = 2y.
We will use that: ln(1) = 0 and [tex]e^{ln(b)}=b[/tex]
[tex]e^{ln(1)}=e^0=1[/tex]
[tex]e^{ln(5x)}=5x[/tex], here b = 5x.
