Music stalls Games stalls Handicraft stalls Ks 3000 Food stalls Ks 4800 (a) How much money was collected by the music stalls? (b) What fraction of the total amount of money was collected by the game stalls? (c) What percentage of the total amount of money was collected by the food stalls? (d) What was the ratio of the money collected by the handicraft stalls to the money collected by the music stalls?
Answers
Answer:
Step-by-step explanation:
a. The music stalls collected Ks 3000.
b. The game stalls collected Ks 4800, which is a fraction of the total amount of money collected. To find the fraction, we can divide the amount collected by the game stalls by the total amount collected by all the stalls:
$\frac{Ks 4800}{Ks 3000 + Ks 4800 + Ks 3000} = \frac{Ks 4800}{Ks 10800} = \frac{2}{9}$
Therefore, the game stalls collected $\frac{2}{9}$ of the total amount of money.
c. The food stalls collected Ks 4800, which is a percentage of the total amount of money collected. To find the percentage, we can divide the amount collected by the food stalls by the total amount collected by all the stalls and multiply by 100%:
$\frac{Ks 4800}{Ks 3000 + Ks 4800 + Ks 3000} \times 100% = \frac{Ks 4800}{Ks 10800} \times 100% = 44.44%$
Therefore, the food stalls collected 44.44% of the total amount of money.
d. The handicraft stalls collected Ks 3000, and the music stalls collected Ks 3000. The ratio of the money collected by the handicraft stalls to the money collected by the music stalls is therefore 1:1. We can write this ratio as $\frac{1}{1} = 1$, or simply as 1.

A bacteria culture contains 2000 bacteria and doubles every half hour, find the size of the bacterial population after 5 hours
Answers
Since the bacteria culture doubles every half hour, the size of the bacterial population after 1 half hour is 2000 * 2 = 4000 bacteria.
The size of the bacterial population after 2 half hours is 4000 * 2 = 8000 bacteria.
This pattern continues, so the size of the bacterial population after 10 half hours (or 5 hours) is 8000 * 2^(10-2) = 8000 * 2^8 = 8000 * 256 = 2048000 bacteria.
Thus, the size of the bacterial population after 5 hours is 2048000 bacteria.

convert the point (4,197) from polar coordinates into rectangular coordinates. round your answers to the nearest tenth (1 decimal place).
Answers
The rectangular coordinates are (-3.825,-1.169).
In a rectangular coordinate system, we were plotting points based on an ordered pair of (x, y). In the polar coordinate system, the ordered pair will now be (r, θ). The ordered pair specifies a point’s location based on the value of r and the angle, θ, from the polar axis.
The value of r can be positive, negative, or zero. The sign of r is very important in locating the exact position of the point. The absolute value of r, |r|, is the distance between the point and the pole.
1. If r is positive (r > 0) then the point lies on the terminal side of θ
2. If r is negative (r < 0) then the point lies on the ray opposite of the terminal side of θ
3. If r is zero (r = 0) then the point lies at the pole regardless of θ
Given,
P= (4,197)
Finding rectangular coordinates (x,y)
x = r cosθ
x = 4 cos 197
x = 4* (-0.956)
x = -3.825
y = r sinθ
y = 4 sin 197
y = 4*(-0.292)
y = -1.169

Answers
The amount borrowed is $66,000, the annual interest rate is 4 %, the number of payments per year is 12, the loan term is 20 years, and the payment amount is $10668.39.
What is compound interest?Compound interest is applicable when there will be a change in the principle amount after the given time period.
For example, if you give anyone $500 at the rate of 10% annually then $500 is your principle amount. After 1 year the interest will be $50 and hence principle amount will become $550 now for the next year the interest will be $550, not $500.
The total amount paid is,
A = 4800[1 + 0.04/12]^(12 x 20)
A = $10668.39
Hence "The amount borrowed is $66,000, the annual interest rate is 4 %, the number of payments per year is 12, the loan term is 20 years, and the payment amount is $10668.39".

What is compound interest?
Compound interest is that the interest on savings calculated on each the initial principal and therefore the accumulated interest from previous periods.
Main body:
Given :
rate = 6%
amount = $900
Total amount = $1800
Compounded monthly,
so formula becomes,
Total amount = amount (1+r/1200)^12t
T = A[tex](1+r/1200)^{12t[/tex]
1800 = 900 (1+6/1200)^12t
2 = (1+1/200)^12t
2 = 1.005^12t
taking log on both sides
log 2 = 12t *log 1.005
0.3/0.002 = 12t
t = 12.5 years
Hence the time taken to double the money is 12.5 years.

Find the coordinates of a point on a circle with radius 10 corresponding to an angle of
325∘
Answers
To find the coordinates of a point on a circle with radius 10 corresponding to an angle of 325 degrees, you can use the following formula:
(x, y) = (r * cos(θ), r * sin(θ))
where (x, y) are the coordinates of the point, r is the radius of the circle, and θ is the angle in radians.
To convert the angle from degrees to radians, you can use the following formula:
θ (radians) = θ (degrees) * (π / 180)
Substituting the values into the formula and converting the angle to radians, you get:
(x, y) = (10 * cos(325 * (π / 180)), 10 * sin(325 * (π / 180)))
= (-5.5, 9.5)
Therefore, the coordinates of the point on the circle with radius 10 corresponding to an angle of 325 degrees are (-5.5, 9.5).
What are the coordinates point?

Answers
The amount A in an account to the nearest cent, the amount A in the account after 10 years is $30,441.65.
What is the amount A in an account?Generally, To find the amount A in the account after 10 years, we can use the formula for continuous compound interest:
A(t) = A(0) * e^(rt)
where A(t) is the amount in the account after t years, A(0) is the initial amount in the account, r is the interest rate, and t is the number of years.
In this case, we know that A(0) = $15,000, A(8) = $22,377.37, and t = 10 years. We can rearrange the formula to solve for r:
r = (1/t) * ln(A(t)/A(0))
Substituting the known values, we get:
r = (1/10) * ln(22377.37/15000)
Solving this equation, we get r = 0.0658082.
Now that we have the value of r, we can use the formula for continuous compound interest to find the amount A in the account after 10 years:
A(10) = 15000 * e^(0.0658082 * 10)
Solving this equation, we get A(10) = $30,441.65.

Answers
A function showing the value of the account after t years, where the annual growth rate can be found from a constant in the function is f(t) = 2900 × (1.0624)^t and APY is 6.24%.
What is Compound Interest?Compound interest in simple words is the interest earning for your savings with the interest which those savings earn.
The formula for calculating the amount in Compound Interest is,
A = P( 1 + [tex]\frac{r}{n}[/tex] )ⁿᵇ
where A is the amount, P is the principal, r is the rate of interest, n is the number of times interest compounded in a year and b is the number of years.
Here, P = $2900, r = 6.1% = 0.061, n = 4 (quarterly) and b = t years
A = 2900 (1 + [tex]\frac{0.061}{4}[/tex])^4t
A = 2900 (1.0153)^4t
A = 2900 × (1.0624)^t
So A can be said as a function of t.
f(t) = 2900 × (1.0624)^t
Percentage of growth per year (APY) = ( 1 + [tex]\frac{r}{n}[/tex] )ⁿ - 1
= (1 + [tex]\frac{0.061}{4}[/tex])⁴ - 1
= 1.0624 - 1
= 0.0624 = 6.24%
Hence the function of the value of the account after t years is f(t) = 2900 × (1.0624)^t, where the value 1.0624 is a constant.
Percentage of growth per year is 6.24%.

The answers to all the parts are given below.
What is a expression? What is a mathematical equation? What do you mean by domain and range of a function?A mathematical expression is made up of terms (constants and variables) separated by mathematical operators. A mathematical equation is used to equate two expressions. Equation modelling is the process of writing a mathematical verbal expression in the form of a mathematical expression for correct analysis, observations and results of the given problem. For any function y = f(x), Domain is the set of all possible values of [y] that exists for different values of [x]. Range is the set of all values of [x] for which [y] exists.We have a function h = -16t² + 1800, that gives the height of the person at time [t] seconds.
[A] -
For [x] = 1000ft, we can write -
1000 = -16t² + 1800
16t² = 800
t² = (800/16)
t² = 50
t = 7.07 seconds
[B] -
For [x] = 950ft, we can write -
950 = -16t² + 1800
16t² = 850
t² = 53.125
t² = √(53.125)
t = 7.29 seconds
[C] -
The domain of the function will be -
0 ≤ x ≤ 10
[D] -
The range of the function will be -
0 ≤ h ≤ 1800
Therefore, the answers to all the parts are given above.

a circle c has center at the origin and radius 4. another circle k has a diameter with one end at the origin and the other end at the point the circles c and k intersect in two points. let p be the point of intersection of c and k which lies in the first quadrant. let be the polar coordinates of p, chosen so that is positive and find and .
Answers
Let (r,q) represent P's polar coordinates, with r being positive and 0 equaling q being pi/2. If so, r = 3m. And A = 0.20136
All points in a plane that are at a specific distance from a specific point, the center, form a circle.
Formula for the first circle: x²+ y² = 9
Formula for the second circle:
center is (0, 7.5) and the radius is 15/2, so
x² + (y - 7.5)² = (7.5)²
Combining these yields:
9 - y² + (y - 7.5)² = (7.5)²
9 - y² + y² - 15y + (7.5)² = 7.5²
9 - 15y = 0
y = 9/15 = 3/5
∴ y = 0.6
x² + y² = 9 = x² + (3/5)²
x² = 9 - (9/25)
x² = [(225 - 9)/25] = 216/25
∴ x = 2.9394
r = √(x² + y²) =
r = √[( 216/25) + (9/25)]
r = √(225/25) = 15/5
∴ r = 3
The x and y values appear to be accurate because this must be the same as the radius of the circle cantered at the origin.
sin(A) = y/r
sin(A) = (3/5)/3 = 1/5
Sin(A) = 0.2
∴ A = 0.20136

Answers
Answer: You would have to know the number of yards separate from his neighbors yard to get the answer.
Step-by-step explanation:
For example if his yard was 50 yards from his neighbors than you would add that to the width. Length plus width to get your answer.
Question 21 of 25
What is the length of the x-component of the vector shown below?
8
71°
OA. 2.6
OB. 8.0
OC. 7.6
OD. 5.2
Answers
Using the Pythagorean theorem, we can find the length of the x-component:
x^2 = 8^2 - 7.1^2
x = sqrt(64 - 50.41)
x = sqrt(13.59)
x = OD. 5.2
Therefore, the length of the x-component is 5.2.
