Answer:

Ayanda will receive R20,160, Zipho will receive R15,120, and Palesa will receive R10,080.

Step-by-step explanation:

We can use the ratio of 4:3:2 to find the total number of parts:

4 + 3 + 2 = 9

This means that the money will be divided into 9 equal parts, and Ayanda will get 4 parts, Zipho will get 3 parts, and Palesa will get 2 parts.

To find the value of one part, we divide the total amount by 9:

45,360 / 9 = 5,040

Therefore, one part is worth R5,040.

Now we can find the amount of money each person will receive by multiplying their respective parts by the value of one part:

Ayanda: 4 parts × R5,040/part = R20,160

Zipho: 3 parts × R5,040/part = R15,120

Palesa: 2 parts × R5,040/part = R10,080

Therefore, Ayanda will receive R20,160, Zipho will receive R15,120, and Palesa will receive R10,080.

Check the picture below.

Therefore, the percentage increase in the price of petrol is approximately 5.57%.

One tenth of any amount is represented by the relative number 10% in the image. Since one percent (1%) represents the one tenth of something, 100 percent (100%) denotes the entire thing, and 200 percent (200%) denotes twice the amount indicated. percentage. Mathematical percentile is a similar subject.

To find the percentage increase in the price of petrol, we can use the formula:

percentage increase = (new value - old value) / old value x 100%

Here, the old value is R12.58 per litre, and the new value is R13.28 per litre. Substituting these values into the formula, we get:

percentage increase = (13.28 - 12.58) / 12.58 x 100%

percentage increase = 0.70 / 12.58 x 100%

percentage increase = 0.0557 x 100%

percentage increase = 5.57%

Therefore, the percentage increase in the price of petrol is approximately 5.57%.

Answer:

6,000 Video Games

Step-by-step explanation:

To find out how many video games Cloey sold on Sunday, we need to add the number of video games she sold on Friday and Saturday and then subtract that total from the total number of video games she sold over the three days:

Total number of video games sold on Friday and Saturday = 3,878 + 8,999 = 12,877

Total number of video games sold over the three days = (number sold on Friday) + (number sold on Saturday) + (number sold on Sunday)

We know that the total number of video games sold over the three days is the sum of the number sold on Friday and Saturday plus the number sold on Sunday. We can rearrange this equation to solve for the number sold on Sunday:

Number sold on Sunday = Total number sold over three days - Number sold on Friday and Saturday

Substituting in the values we know, we get:

Number sold on Sunday = (number sold on Friday) + (number sold on Saturday) + (number sold on Sunday) - (number sold on Friday) - (number sold on Saturday)

Number sold on Sunday = Total number sold over three days - Number sold on Friday and Saturday

Number sold on Sunday = (3,878 + 8,999 + X) - 12,877

Number sold on Sunday = X - 0

Simplifying this expression, we get:

Number sold on Sunday = 6,000

Therefore, Cloey sold 6,000 video games on Sunday.

The zeros ( roots ) of the function y = (x + 2)^2 - 25 are x = 3 and x = -7.

Given the function in the question;

y = ( x + 2 )² - 25

To find the zeros of the function, simply means find the values of  x in the function y = ( x + 2 )² - 25, when y equals zero.

Equat the function to 0

(x + 2)^2 - 25 = 0

Adding 25 to both sides, we get:

(x + 2)^2 - 25 + 25  = 0 + 25

(x + 2)^2  = 25

Taking the square root of both sides, we get:

x + 2 = ±√25

x + 2 = +5

Solving for x, we get:

x = -2 + 5 = 3

or x = -2 - 5 = -7

Therefore, the zeros of the function are 3 and -7.

Option 4) -7 and 3 is the correct answer.

Let the 7 letters A through G represent the ages of the 7 person family.

7/2 = 3.5 which rounds to 4 represents the slot number of the median, aka the middle-most position. The 4th letter is D. Because the median is 16, we know that D = 16.

We go from this

A,B,C,  D,  E,F,G

to this

A,B,C,  16,  E,F,G

I put a bit of spacing to help show why D is the middle.

-------------------

The modes are 12 and 45, which means those values show up more than once. Let's assume they show up 3 times each.

That tells us A,B, and C are all equal to 12. Furthermore, that assumption indicates E,F,G are all equal to 45.

We go from this

A,B,C,  16,  E,F,G

to this

12,12,12,  16,  45,45,45

But we run into a problem. The range is max-min = 45-12 = 33 and not 35 like we want.

We have no choice but to remove one copy of "12" and remove one copy of "45". We need to remove both because removing only one of those would result in the mode being just one value (rather than two).

-------------------

So we have this now

A,12,12,  16,  45,45,G

where A < 12 and G > 45

range = max - min = G-A = 35

G-A = 35 solves to G = 35+A

We can update the set to

A,12,12,  16,  45,45,35+A

-------------------

Now to figure out what "A" is.

The bit of info we haven't used yet is the mean.

Recall the mean has us add up the numbers and then divide by the number of values.

mean = (sum of the values)/(number of values)

mean = (A+B+C+D+E+F+G)/7

mean = (A+12+12+16+45+45+35+A)/7

mean = (2A+165)/7

Set that equal to the stated mean of 23 so we can solve for "A".

mean = (2A+165)/7

(2A+165)/7 = 23

2A+165 = 7*23

2A+165 = 161

2A = 161-165

2A = -4

A = -4/2

A = -2

That's not good. We should have gotten a positive whole number for "A". Since "A" is negative, it means there is a typo somewhere in the given instructions.

It's impossible to have a family of 7 people where the mean age is 23, the median is 16,  the modes are 12 and 45, and the range is 35. At least one of those starting values needs to change. If for instance the "45"s were changed to "41", then the equation above would solve to A = 2.

I would ask your teacher for clarification.

Step-by-step explanation:

Answer:

Step-by-step explanation:

This problem involves a binomial distribution where the probability of success (passing on the first attempt) is 0.65, and the probability of failure (not passing on the first attempt) is 0.35. We want to find the probability that less than 3 out of 5 people pass on their first attempt.

We can use the binomial probability formula to calculate this:

P(X < 3) = P(X = 0) + P(X = 1) + P(X = 2)

Where X is the number of people who pass on their first attempt.

P(X = 0) = (5 choose 0) * 0.65^0 * 0.35^5 = 0.0024

P(X = 1) = (5 choose 1) * 0.65^1 * 0.35^4 = 0.0289

P(X = 2) = (5 choose 2) * 0.65^2 * 0.35^3 = 0.1323

So,

P(X < 3) = 0.0024 + 0.0289 + 0.1323 = 0.1636

Therefore, the probability that less than 3 out of 5 people pass their driver's tests on the first attempt is approximately 0.164, rounded to three decimal places.

Step-by-step explanation:

A = age of Anthony

K = age of Kadeesha

Formulate equations based on the information given:

K = A + 1

A² + 2K = 82

Solve the simultaneous equations by substitution:

A² + 2(A + 1) = 82

A² + 2A + 2 = 82

A² + 2A - 80 = 0

(A + 10)(A - 8) = 0

A + 10 = 0 → A = -10

A - 8 = 0 → A = 8

Anthony can't be -10yo, so he is 8yo

Kadeesha is, therefore, 9yo

The variable cost for x doughnuts produced is 0.25x.

What is variable cost?

Costs that vary according on how much of an item or service a company produces are known as variable costs.

The fixed cost for the company is $25,000, which is a constant amount that does not depend on the number of doughnuts produced. The variable cost, on the other hand, is the cost that varies with the number of doughnuts produced.

Since it costs $0.25 to produce each doughnut, the variable cost for x doughnuts can be calculated as 0.25x.

Therefore, the variable cost for x doughnuts produced is 0.25x.

Answer:

Step-by-step explanation:

To find the center and radius of the circle represented by the equation:

x^2 + y^2 - 8x - 20y + 52 = 0

We can start by completing the square for both x and y terms as follows:

(x^2 - 8x) + (y^2 - 20y) + 52 = 0

(x^2 - 8x + 16) + (y^2 - 20y + 100) + 52 = 16 + 100

(x - 4)^2 + (y - 10)^2 = 64

Thus, the equation can be rewritten in the standard form of the circle as:

(x - 4)^2 + (y - 10)^2 = 8^2

Therefore, the center of the circle is (4, 10), and its radius is 8 units.

Step-by-step explanation:

x² + y² - 8x - 20y + 52 = 0

the standard circle equation is

(x - h)² + (y - k)² = r²

where (h, k) is the center of the circle, and r is the radius.

now, we need to find the squared terms in the original equation.

x² and y² are clearly from the (x - h)² and (y - k)².

and then

(x - h)² = x² - 2hx + h²

-2hx = -8x

2h = 8

h = 4

(y - k)² = y² - 2ky + k²

-2ky = -20y

2k = 20

k = 10

h² + k² = 16 + 100 = 116

116 - r² = 52

r² = 64

r = 8

so, the center is (4, 10), the radius is 8.

C. An altitude of 7 km above sea level

At an altitude of 7 km above sea level, a person would experience the least atmospheric pressure because they would be furthest from the earth's surface and there would be very little air above them. This is why the air pressure in the Earth's upper atmosphere is much lower than at the surface of the Earth.

Step-by-step explanation:

96 / 24 = 4, 28/ 7 = 4, assuming that it dilated by 4, so use 4 to multiply 25, 4 x 25 = 100 so 6x+28 = 100 then plug it in 6(12) + 28 = 100., 100 = 100

To check use a^2 + b^2 = c^2

28^2 + 96^2 = (6(12)+28)^2

784 + 9216 = (72+28)^2

784 + 9216 = 100^2

784 + 9216 = 10000

C) To simplify the first ratio, we can divide both the numerator and denominator by 6, giving us 3/8. To simplify the second ratio, we can divide both the numerator and denominator by 7, giving us 3/8. Since these simplified ratios are equal, the two ratios are proportional.

D) To simplify the first ratio, we can multiply both the numerator and denominator by 2, giving us 6/10, which simplifies to 3/5. The second ratio is already in simplified form. Since these simplified ratios are not equal, the two ratios are not proportional.

Malik: y = (x-400) / 2

Jacob: y = x/2 - 400

So, if we consider y as the money donated for the animal shelter and x is the total-raised money,

Answer:

The first step is to calculate the daily interest rate. We can do this by dividing the annual percentage rate (APR) by 365 (the number of days in a year):

Daily interest rate = 15% / 365 = 0.00041096

Next, we need to calculate the interest that accrues on the outstanding balance for the first month. Since there are 30 days in a typical month, we can multiply the daily interest rate by the outstanding balance and the number of days in the month:

Interest for first month = 0.00041096 × $400 × 30 = $4.93

This means that the outstanding balance after the first payment will be:

$400 + $4.93 - $75 = $329.93

So the balance after the first payment will be $329.93.

Answer:

Step-by-step explanation:

Let's assume that the normal air pressure in the Florida Keys before the hurricane is represented by the variable 'p'. The inequality that could be used to find 'p' based on the given information is:

p - 121 > n

This inequality states that the difference between the normal air pressure 'p' and the air pressure during the hurricane ('n') is greater than 121 millibars. By rearranging this inequality, we can solve for 'p':

p > n + 121

Therefore, the normal air pressure in the Florida Keys before the hurricane was greater than the air pressure during the hurricane plus 121 millibars.
