Every 6 days John eats 20 ounces of cereal. At the same rate, how many ounces of cereal will John eat in 15 days?
Multiplication is the process of multiplying. The amount of cereal that John will eat in 15 days is 50 ounces.
What is multiplication?Multiplication is the process of multiplying, therefore, adding a number to itself for the number of times stated. For example, 3 × 4 means 3 is added to itself 4 times, and vice versa for the other number.
Given that John eats 20 ounces of cereal every 6 days. Therefore, the amount of cereal that John eats every 6 days is,
Amount of cereal in a day = 20 ounces / 6 days
= (20/6) ounces in a day
Now, the amount of cereal that John will eat in 15 days is,
Amount of cereal in 15 days = 15 days × (20/6) ounces in a day
= 50 ounces
Hence, the amount of cereal that John will eat in 15 days is 50 ounces.

The radioactive substance cesium-137 has a half-life of 30 years. The amount A (r) (in grams) of a sample of cesium-137 remaining after t years is
given by the following exponential function.
A (t)-266 6 (1) 10
Find the initial amount in the sample and the amount remaining after 50 years.
Round your answers to the nearest gram as necessary.
Initial amount:
Amount after 50 years:
The amount remaining after 50 years is approximately 45.5% of the Initial amount, A₀.
The given exponential function represents the amount A(t) (in grams) of cesium-137 remaining after t years:
A(t) = A₀ * (1/2)^(t/30)
We are asked to find the initial amount A₀ and the amount remaining after 50 years.
1. Initial amount:
The initial amount, A₀, is the amount of cesium-137 present at t = 0 years. To find A₀, we substitute t = 0 into the equation:
A(0) = A₀ * (1/2)^(0/30)
A(0) = A₀ * 1
Since anything raised to the power of zero is 1, we have A(0) = A₀ * 1, which simplifies to A(0) = A₀.
Therefore, the initial amount of the sample is A₀.
2. Amount after 50 years:
To find the amount remaining after 50 years, we substitute t = 50 into the equation:
A(50) = A₀ * (1/2)^(50/30)
Now we can calculate the amount using the given formula:
A(50) = A₀ * (1/2)^(5/3)
To round the answer to the nearest gram, we evaluate the expression and round the result to the nearest gram:
A(50) = A₀ * 0.455
A(50) ≈ A₀ * 0.455
Therefore, the amount remaining after 50 years is approximately 45.5% of the initial amount, A₀.

Your grade before taking the final exam is 493pts out of 510 possible points. The final exam is worth 100 points. How many points do you have to get on the final exam to get 93% overall for the class
Answer:
You need 75 points.
Step-by-step explanation:
Giving the following information:
Total number of points= 510 + 100= 610 (100%)
Actual number of points= 493
First, we need to determine the number of points required to reach 93%:
Points required= 610*0.93
Points required= 567.3 = 568
Now, the points needed in the final exam:
Difference of points= 568 - 493
Difference of points= 75 points
You need 75 points.

Step 2 The admission price increased by 50%. Complete the bar diagram that represents 150% of the price 5 years ago. price 5 years ago = $3 So, the current admission price is current price = + or --- increase 150%
The bar diagram representing 150% of the price 5 years ago would be a bar with a height of $4.50.
What is the percentage?
Percentage is a way to express a number as a fraction of 100. It is often used to describe the relationship between two quantities, or to express a rate or change in a quantity over time. The symbol for percent is "%".
For example, if a pizza is marked up by 20%, it means the price has increased by 20/100 or 1/5 of the original price. If a student scores 80% on a test, it means they got 80 out of 100 questions correct. If a stock's value increases by 10%, it means the value has gone up by 10/100 or 1/10 of the original value.
The current admission price is $3 + $3 * 50% = $3 + $1.50 = $4.50.
150% of the price 5 years ago is $3 * 150% = $3 * 1.5 = $4.50.
So, the bar diagram representing 150% of the price 5 years ago would be a bar with a height of $4.50.

PLS HELP ASAP:Find all the missing elements:
Answer:
b ≈ 9.5, c ≈ 14.7
Step-by-step explanation:
Using the Sine rule in Δ ABC, that is
\(\frac{a}{sinA}\) = \(\frac{b}{sinB}\) , substitute values
\(\frac{7}{sin23}\) = \(\frac{b}{sin32}\) ( cross- multiply )
b × sin23° = 7 × sin32° ( divide both sides by sin23° )
b = \(\frac{7sin32}{sin23}\) ≈ 9.5 ( to the nearest tenth )
Also
\(\frac{a}{sinA}\) = \(\frac{c}{sinC}\)
\(\frac{7}{sin23}\) = \(\frac{c}{sin125}\) ( cross- multiply )
c × sin23° = 7 × sin125° ( divide both sides by sin23° )
c = \(\frac{7sin125}{sin23}\) ≈ 14.7 ( to the nearest tenth )

Use cross multiplication\(\\ \sf\longmapsto y=5x\dots(1)\)
Now
As its a triangle
\(\\ \sf\longmapsto 90+x+y=180\)
Put y=5x\(\\ \sf\longmapsto 90+x+5x=180\)
\(\\ \sf\longmapsto 6x+90=180\)
\(\\ \sf\longmapsto 6x=180-90\)
\(\\ \sf\longmapsto 6x=90\)
\(\\ \sf\longmapsto x=\dfrac{90}{6}\)
\(\\ \sf\longmapsto x=15\)
We need not to find y
See the marked angle and x are supplementary angles hence there sum will be 180

Answer:
f(x) = {0, x≤ 1; 4(x -1), 1 < x ≤ 6; 2.5x +5, x > 6}
Step-by-step explanation:
The hourly rate gives you the slope of the function in the relevant interval. The added constant is chosen to make the function continuous.
That is, at 1 hour, the charge is zero, so the next segment (4x+b) must have a value of b that makes the charge for 1 hour be zero. That will be b=-4.
Likewise, for more than 6 hours, the charge will be (2.5x+b), where b is chosen to make this expression match the charge for 6 hours. We know the charge for 6 hours is 4(6) -4 = 20, so b must match ...
2.5(6) +b = 20
b = 20 -15 = 5
The segment from 1 to 6 hours is f(x) = 4x -4.
The segment for more than 6 hours is f(x) = 2.5x +5.
_____
Alternate solution
Since the charge is zero for the first hour, the first segment could be considered to be charging only for hours after the first. That is, an alternate expression for hours 1–6 could be 4(x -1). Likewise, we could say the expression for hours more than 6 is 2.5(x +2).

If a sample consists of 600 test scores, 516 of them would be at or below the 86th percentile. If a sample consists of 600 test scores, 228 of them would be at or above the 62th percentile.
What is percentile?A percentile is a score that compares a specific score to the scores of the other members of a group. It displays the proportion of other scores that a given score outperformed. For instance, if you have a test score of 75 and are placed in the 85th percentile, it signifies that your score is greater than those of 85% of other test takers.
Given that,
In general, 70 % of the values in a data set lie at or below the 70th percentile.
20 % of the values in a data set lie at or above the 20th percentile.
Generally percentile defines the percentage of a data set that is below or at a value that is being considered.
Hence the percentage of the values of a data set that lies below or at the 16th percentile is 16%
Also the values of a data set that lies below or at the 24th percentile is 24%
Given a sample of 600 test scores , the number of test scores that will be at or below the 86th percentile is 86% of 600 which is mathematically represented as:
K = \(\frac{86}{100}\) × 600
K = 516 test scores
Given a sample of 600 test scores , the number number of test scores that will be above the 62 th percentile is (100 - 62 = 38 )% of 600 which is mathematically represented as:
a = \(\frac{38}{100}\) × 600

Using the radius of the Ferris wheel and the angle between the two positions, the time spent on the ride when they're 28 meters above the ground is 12 minutes
How many minutes of the ride are spent higher than 28 meters above the ground?The radius of the Ferris wheel is 30 / 2 = 15 meters.
The highest point on the Ferris wheel is 15 + 4 = 19 meters above the ground.
The time spent higher than 28 meters is the time spent between the 12 o'clock and 8 o'clock positions.
The angle between these two positions is 180 degrees.
The time spent at each position is 10 minutes / 360 degrees * 180 degrees = 6 minutes.
Therefore, the total time spent higher than 28 meters is 6 minutes * 2 = 12 minutes.

(-40, -30)
Finish
(10, 20)
Monkey

The total distance of the obstacle course can be calculated by finding the distance between each pair of consecutive points and adding them up. The distance between two points (x1, y1) and (x2, y2) can be calculated using the formula: distance = sqrt((x2 - x1)^2 + (y2 - y1)^2).
Using this formula, we can calculate the distances between each pair of consecutive points as follows:
Start to Tire Race: distance = sqrt((-40 - (-40))^2 + (-30 - (-10))^2) = 20 yards
Tire Race to Rope Climb: distance = sqrt((40 - (-40))^2 + (-30 - (-30))^2) = 80 yards
Rope Climb to Monkey Bars: distance = sqrt((40 - 40)^2 + (20 - (-30))^2) = 50 yards
Monkey Bars to Finish: distance = sqrt((10 - 40)^2 + (20 - 20)^2) = 30 yards
Adding up all these distances, we get a total distance of 20 + 80 + 50 + 30 = 180 yards for the obstacle course.

The area of the base of a square pyramid is 36 in². The height of each triangular face of the pyramid is 4 in.
What is the surface area of the pyramid?
72 in²
84 in²
96 in²
108 in²
Answer:
the answer is option (B) 84 in².
Step-by-step explanation:
The surface area of a square pyramid can be calculated by finding the sum of the areas of the four triangular faces and the base.
The area of the base is given as 36 in². Since the base is a square, we can find the length of one side of the base by taking the square root of the area:
sqrt(36 in²) = 6 in
Therefore, the length of one side of the base is 6 in.
To find the area of one of the triangular faces, we can use the formula for the area of a triangle:
Area = 1/2 * base * height
In this case, the base is equal to the length of one side of the square base, or 6 in. The height is given as 4 in.
Area = 1/2 * 6 in * 4 in = 12 in²
So the area of one triangular face is 12 in².
The total surface area of the pyramid is:
Surface area = 4 * 12 in² + 36 in² = 84 in²
Therefore, the surface area of the pyramid is 84 in².
So the answer is option (B) 84 in².

Step-by-step explanation:
An interior designer wants to decorate a newly constructed house. The function f (x) = 49x2 – 200 represents the amount of money he earns per room decorated, where x represents the number of rooms he designs. The function g of x equals one seventh times x represents the number of rooms the interior designer decorates, where x is the number of hours he works.
Part A: Determine the amount of money the interior designer will make decorating the house as a function of hours he works. (5 points)
Part B: If the newly constructed house requires 50 hours of work, how much will the interior designer earn? Show all necessary calculations. (5 points)
Part C: Determine an expression to represent the difference quotient for the function found in Part A. Show all necessary work. (5 points)
A. x² - 200 gives the amount of money the interior designer will make decorating the house as a function of hours he works.
B. He will earn 1,875 if he works for 50 hours.
C. The difference quotient is equal to 2x.
The solution has been obtained by using functions.
What is a function?
Function is a kind of relation, or rule, that associates a single input with a single, predetermined output.
We are given two functions
f(x) = 49x² – 200
which represents the amount of money he earns per room decorated
g(x) = (1/7)x
which represents the number of rooms the interior designer decorates
A. The amount of money the interior designer will make decorating the house as a function of hours he works will be given by evaluating f(x) in g(x).
So,
f(g(x)) = 49((1/7)x)² – 200
f(g(x)) = x² - 200
B. Since, the house requires 50 hours of work, this means that x = 50.
Substituting this in f(g(x)) = x² - 200, we get
f(g(50)) = 50² - 200
f(g(50)) = 1,875
C. The difference quotient for the function is as follows
\(\lim_{h \to \ 0}\frac{f(x+h) -f(x)}{h}\)
\(\lim_{h \to \ 0}\frac{(x+h)^{2}-200-x^{2}+200}{h}\)
\(\lim_{h \to \ 0}\frac{x^{2} + 2xh + h^{2}-x^{2}}{h}\)
= 2x
Hence, x² - 200 gives the amount of money and he earns 1,875 if he works for 50 hours. The difference quotient is equal to 2x.
