Country A has a growth rate of 4.9% per year. The population is currently 4 comma 151,000, and the land area of Country A is 14,000,000,000 square yards. Assuming this growth rate continues and is exponential, after how long will there be one person for every square yard of land?
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.

Write in slope-intercept form an equation of the line that passes through the given points.
(6,8),(3,−9)
Slope-intercept form: [tex]y=mx+b[/tex]
m = slopeb = y-interceptSlope formula: [tex]m=\dfrac{y_2-y_1}{x_2-x_1}[/tex]
[tex](x_1,y_1)[/tex] and [tex](x_2,y_2)[/tex] are two points that fall on the lineSolving the Question
We're given:
The line passes through (6,8), (3,-9)1) First, find the slope using the slope formula:
[tex]m=\dfrac{y_2-y_1}{x_2-x_1}[/tex]
[tex]m=\dfrac{8-(-9)}{6-3}\\\\m=\dfrac{8+9}{6-3}\\\\m=\dfrac{17}{3}[/tex]
Therefore, the slope of this line (m) is [tex]\dfrac{17}{3}[/tex]. Plug this into slope-intercept form:
[tex]y=\dfrac{17}{3}x+b[/tex]
2) Now, find the y-intercept by using one of the given points:
[tex]y=\dfrac{17}{3}x+b[/tex]
Plug in one of the given points as (x,y):
[tex]8=\dfrac{17}{3}(6)+b\\\\8=34+b\\b=8-34\\b=-26[/tex]
Therefore, the y-intercept of the line is -26. Plug this into our original equation:
[tex]y=\dfrac{17}{3}x+b\\\\y=\dfrac{17}{3}x-26[/tex]
Answer[tex]y=\dfrac{17}{3}x-26[/tex]
To write the equation of the line in slope-intercept form, which is y = mx + b, where m is the slope and b is the y-intercept, we need to determine the slope first and then use one of the points to find the y-intercept.
Step 1: Find the slope (m)
The slope of a line passing through two points, (x1, y1) and (x2, y2), can be calculated using the formula:
m = (y2 - y1) / (x2 - x1)
Given our points (6, 8) and (3, -9), we can substitute them into our formula:
x1 = 6, y1 = 8
x2 = 3, y2 = -9
m = (-9 - 8) / (3 - 6)
m = (-17) / (-3)
m = 17/3
m = 5.666666666666667 (rounded to 5.67 for simplicity)
Step 2: Find the y-intercept (b) using one of the points
Next, we can use the point-slope form of a line equation, which is:
y - y1 = m(x - x1)
We will use the first point (6, 8) and the slope m = 5.67 that we calculated.
Substitute the point and the slope into the point-slope form equation:
8 - y1 = 5.67(6 - x1)
Since we know that (x1, y1) is (6, 8), this simplifies to:
8 - 8 = 5.67(6 - 6)
b = 8 - 5.67(6)
Now, we do the multiplication and subtraction:
b = 8 - 34.02
b = -26
So now we have our y-intercept, which is b = -26.
Step 3: Write the equation in slope-intercept form
Now that we have both m and b, we can write the equation of the line:
y = mx + b
Substitute m and b into the equation:
y = 5.67x - 26
This is the equation of the line in slope-intercept form that passes through the points (6, 8) and (3, -9). For exact calculations, you may want to use the more precise value of the slope (5.666666666666667) in the equation:
y = 5.666666666666667x - 26
By doing so, we obtain a more accurate representation of the line's equation.

Answer and Step-by-step explanation:
Since this is a quadrilateral, we know that all the angles will add up to 360 degrees (by definition). We are given that angle A is 90 degrees and that the ratio of A to B is 5 to 3. This means that we can set up a proportion and solve for B:
A/B = 5/3 ⇒ 90/B = 5/3 ⇒ 5B = 270 ⇒ B = 54
So, we know that angle B is 54 degrees.
Now that we know angle B is 54 and A is 90, we can find the sum of the remaining two angles X and Y because A + B + X + Y = 360:
90 + 54 + X + Y = 360
X + Y = 216 degrees
We also know that the ratio of X to Y is 1 to 3, so we can set up another proportion:
X/Y = 1/3 ⇒ Y = 3X
Substitute 3X in for Y in X + Y = 216:
X + 3X = 216
4X = 216
X = 54
Thus, we see that both angles B and X equal 54, so B = X.
Hope this helps!
Answer:
[tex]\frac{a}{b}=\frac{5}{3}=>b=\frac{3a}{5}=\frac{270}{5}=54 \\\\x+y=360-(90+54)=360-144=216\\\\\frac{x}{y}=\frac{1}{3}=>y=3x\\ \\x+3x=216\\\\4x=216\\\\x=216:4\\\\x=54\\\\x=b\\[/tex]
Two cards are selected from a deck of cards numbered from 1 to 10. Once a card is selected, it is not replaced. What is P(two even numbers)? Write the answer as a fraction in simplest form.
Include Explanation please
10 cards would have 5 even cards.
First pick would be 5/10 = 1/2 probability of getting an even card.
Without replacing there are 9 cards left with 4 even ones. The probability of picking an even card would be 4/9
The probability of both happening would be Found by multiplying the two probability’s together:
1/2 x 4/9 = 4/18 = 2/9
Two cards are selected from a deck of cards numbered from [tex]1[/tex] to [tex]10[/tex] and once a card is selected, it is not replaced, then Probability of two even numbers is [tex]\frac{2}{9}[/tex] .
What is Probability ?Probability is a ratio of the number of favorable outcomes to the number of possible outcomes of the experiment.
Probability[tex](E)[/tex] [tex]=\frac{Number \ of \ favorable \ outcomes}{Number \ of \ possible \ outcomes \ of \ the \ experiment}[/tex]
We have,
Let [tex]E[/tex] be event of drawing cards.
A deck of cards numbered from [tex]1[/tex] to [tex]10[/tex] .
i.e. total number of possible outcomes [tex]=10[/tex]
And,
Even numbers from [tex]1[/tex] to [tex]10[/tex] are [tex]2,4,6,8,10[/tex]
[tex]=10[/tex]
Total even numbers are [tex]5[/tex].
So,
Probability[tex](E)[/tex] [tex]=\frac{Number \ of \ favorable \ outcomes}{Number \ of \ possible \ outcomes \ of \ the \ experiment}[/tex]
Probability[tex](E)[/tex] [tex]=\frac{5}{10}*\frac{4}{9}[/tex]
[tex]=\frac{2}{9}[/tex]
So, the Probability of two even numbers is [tex]\frac{2}{9}[/tex] , as there are total [tex]10[/tex] cards and it is said that once a card is selected, it is not replaced, so when one card is selected there remains only [tex]9[/tex] cards, so when next time we select a card then Probability will be from those [tex]9[/tex] cards.

The scale on a map reads 1/2 inch = 75 miles. If the distance between two cities on the map is 3 and 1/4 inches, find the actual distance between the cities
Answer:
487.5 miles
Step-by-step explanation:
The actual distance between the cities is 487.5 miles.
What is Proportion?Two or more ratios made to be equivalent to each other is termed as the method of proportion.
That is, if 'a' related to 'b' is proportional to 'p' related to 'q', then,
a : b : : p : q
⇒ a/b = p/q
⇒ aq = bp
Here we have the scale on a map reads 1/2 inch as 75 miles.
We have to find the actual distance of two cities if the distance between the cities in the map is 3 and 1/4 inches.
3 and 1/4 inches = (3 × 4 + 1) / 4 = 13/4 inches.
Let x be the actual distance between the cities.
Using proportion,
1/2 : 75 : : 13/4 : x
[tex]\frac{1/2}{75}[/tex] = [tex]\frac{13/4}{x}[/tex]
1/2 × x = 13/4 × 75
1/2 × x = 243.75
x = 487.5
Hence the actual distance between the cities is 487.5 miles.

Triangle R has an area of 40 square units. Salome drew a scaled version of triangle R and labeled it triangle T what scale factor did salome use to go from triangle R to triangle T
Answer:
Scale factor = 1/2
Ratio R:T = 2:1
Attached is the missing image;
Step-by-step explanation:
From the image attached;
The height of the triangle T is = 5 units
Base of triangle T = 4 units
Since the two triangles are scaled versions;
Area of a triangle = 1/2 × h × b
For triangle R;
Area = 40 = 1/2 × h × b
hb = 80
And, h : b = 5:4
h= 5/4 b
5/4 ×b × b = 80
b^2 = 64
b = 8
h = 5/4 × 8 = 10
The height of the triangle R = 10 units
Base of triangle R = 8 units
Scale factor = h2/h1 = 5/10 = 1/2
Scale factor = 1/2

18/3=6 ft per year
The equivalent rates to 6 feet per year are 18 inches per year, 12 feet in 4 years, 72 inches per year, 2 yards per year, and 18 feet in 3 years.
Explanation:The student is asking about equivalent rates. To determine which rates are equivalent to 6 feet per year, we need to compare each option against the given rate. The conversion factors needed for this problem are:
1 foot = 12 inches1 yard = 3 feetOption A: 2 inches per year is not equivalent to 6 feet per year.
Option B: 18 inches per year is equivalent to 6 feet per year because 18 inches is 1.5 feet, and thus, 1.5 feet multiplied by 4 would give us 6 feet in 4 years.
Option C: 12 feet in 4 years is equivalent to 6 feet per year because dividing 12 feet by 4 years gives us 3 feet per year, which is half of the given rate.
Option D: 72 inches per year is equivalent to 6 feet per year because 72 divided by 12 is 6.
Option E: 2 yards per year is equivalent to 6 feet per year because 2 multiplied by 3 is 6.
Option F: 18 feet in 3 years is equivalent to 6 feet per year because dividing 18 feet by 3 years gives us 6 feet per year.
Thus, the equivalent rates to 6 feet per year from the options given are 18 inches per year, 12 feet in 4 years, 72 inches per year, 2 yards per year, and 18 feet in 3 years.

Brian pays £475.29 a year on his car insurance. The insurance company reduces the price by 2.1%. How much does the insurance cost now? Give your answer rounded to 2 DP.
Answer:
[tex]\£465.31[/tex]
Step-by-step explanation:
we know that
The insurance company reduces the price by 2.1%
Remember that
The actual cost of £475.29 a year represent the 100%
so
[tex]100\%-2.1\%=97.9\%=97.9/100=0.979[/tex]
To find out the new insurance cost, multiply the original cost by the factor 0.979
[tex]\£475.29(0.979)=\£465.31[/tex]
Brian's car insurance, after a 2.1% reduction from the original cost of £475.29, is now £465.31 when rounded to two decimal places.
Explanation:Brian's original car insurance cost is £475.29, and the company is offering a reduction of 2.1% on this cost. To calculate the reduced cost, we first find the discount amount by multiplying the original cost by the reduction percentage:
Discount = Original Cost x Reduction Percentage
Discount = £475.29 x 0.021
Discount = £9.98109
Now, we subtract the discount from the original cost to find the new cost of the insurance:
New Cost = Original Cost - Discount
New Cost = £475.29 - £9.98109
New Cost = £465.30891
When rounding to two decimal places, Brian's new cost for car insurance is:
New Cost = £465.31

Response:
[tex]\widehat{AU}[/tex] is 50°Which methods can be used to find [tex]\widehat{AU}[/tex] ?According to circle theorem, we have;
Angle at the center = 2 × Angle at the circumference∠QUA = 111°
Therefore;
[tex]m\widehat{QDA}[/tex] = 2 × ∠QUA
[tex]m\widehat{QDA}[/tex] = 2 × 111° = 222°

A backyard pool has a concrete walkway around it that is 3 feet wide on all sides. The total area of the pool and the walkway is 950 ft2. If the length of the pool is 8 feet longer than the width, find the dimensions of the pool.
Answer:
[tex]x \approx 21.080\,ft[/tex], [tex]y = 29.080\,ft[/tex]
Step-by-step explanation:
The total area of the pool and the walkway is:
[tex](x + 6\,ft)\cdot (y + 6\,ft) = 950\,ft^{2}[/tex]
[tex](x + 6\,ft)\cdot (x + 14\,ft) = 950\,ft^{2}[/tex]
[tex]x^{2} + 20\cdot x + 84\,ft^{2} = 950\,ft^{2}[/tex]
[tex]x^{2} + 20\cdot x - 866\,ft^{2} = 0[/tex]
The roots of the second-order polynomial is:
[tex]x_{1} \approx 21.080\,ft[/tex] and [tex]x_{2} \approx -41.081\,ft[/tex]
The only possible root is:
[tex]x \approx 21.080\,ft[/tex]
The other dimension of the pool is:
[tex]y = x + 8\,ft[/tex]
[tex]y = 21.080\,ft + 8\,ft[/tex]
[tex]y = 29.080\,ft[/tex]

(b) What percent of the college graduates donated to exactly one of the three listed causes?
Answer:
Step-by-step explanation:
The Venn diagram representing this situation is shown in the attached photo.
P represents the set of college graduates that donated to a political campaign.
M represents the set of college graduates that donated to assist medical research.
E represents the set of college graduates that donated to preserve the environment.
From the diagram,
The number of college graduates that donated to all three is 25
The number of college graduates that donated to a political campaign and medical research only is
38 - 25 = 13
The number of college graduates that donated to a political campaign and preserve the environment only is
54 - 25 = 29
The number of college graduates that donated to medical research and to preserve the environment only is 46 - 25 = 21
The number of college graduates that donated to a political campaign only is
95 - (29 + 25 + 13) = 28
The number of college graduates that donated to medical research only is
76 - (13 + 25 + 21) = 17
The number of college graduates that donated to preserve the environment only is
133 - (29 + 25 + 21) = 58
a) the number of college graduates that donated to none is
489 - (28 + 17 + 58 + 13 + 21 + 29 + 25)
= 298 college graduates
b) the number of college graduates that donated to exactly one of the three listed causes is
28 + 17 + 58 = 103
The percentage would be
103/489 × 100 = 21.1%
A fountain in the park has two circular pools that are the same size. What is the total area of the pools if the radius is 3 yards? Use 3.14 for Pi and round the approximate area to the nearest tenth, if necessary. Check all that apply.
Answer:
56.6 square yards.
Step-by-step explanation:
Given:
A fountain in the park has two circular pools that are the same size.
Question asked:
What is the total area of the pools if the radius is 3 yards ?
Solution:
First of all we will calculate the area of a circular pool.
As we know:
[tex]Area\ of\ circle=\pi r^{2}[/tex]
[tex]=\frac{22}{7} \times(3)^{2} \\ \\ =\frac{22}{7}\times9\\ \\ =\frac{198}{7} \\ \\ =28.28\ square\ yards[/tex]
Area of circular pool nearest tenth = 28.3 square yards
Now, as given that both pools are of same size.
Total area of the pools = 28.3 square yards + 28.3 square yards
= 56.6 square yards.
Thus, the total area of the pools are 56.6 square yards.
Answer:
ur answer is 56.5 and 18

Step-by-step explanation:
y= 0.216 x + 32.575
what is the slope
Given:
The given equation of the line is [tex]y=0.216x+32.575[/tex]
We need to determine the slope of the equation.
Slope:
Let us determine the slope of the equation.
The general form of the equation of the line is given by
[tex]y=mx+b[/tex]
where m is the slope of the equation and b is the y - intercept.
Now, we shall compare the general form of the equation of the line with the given equation, we have;
[tex]m= 0.216[/tex] and [tex]b=32.575[/tex]
Thus, the slope of the equation of the line is [tex]m= 0.216[/tex]
the slope is 0.216
And just in case you need it the y-intercept is 32.575
I hope this was helpful :)
