Mary can bake 8 cakes the with 7 cups of flour she possesses because we are unable to create a quarter of a cake.
What is the flour recipe?Starch, a polymer, is one of the ingredients in all-purpose flour, which has the chemical formula (C6H5O10)n (C 6 H 5 O 10) n.
We need to divide Mary's total flour supply by the quantity of flour required for creating one cake in order to determine how many cakes she can produce.
First, we must divide 5 by 6 to get the fraction 5/6 in decimal form:
5 ÷ 6 = 0.8333...
Hence, 0.8333 cups of flour are required to produce one cake.
We're able to divide Mary's entire flour supply by the quantity of flour needed to produce one cake:
7 cups of flour ÷ 0.8333 cups of flour per cake = 8.4 cakes

A city has 14200 people in a random sample of 80 people from the city 43 people say that have visited the city’s community garden which expression can you use to estimate the number of people in the city who have visited the city’s community garden
Answer:
we can estimate that about 7632 people in the city have visited the city's community garden.
Step-by-step explanation:
You can use a proportion to estimate the number of people in the city who have visited the city's community garden. The proportion is:
(Number of people in the city who have visited the community garden) / (Total number of people in the city) = (Number of people in the sample who have visited the community garden) / (Total number of people in the sample)
We can plug in the values given in the problem to get:
(x) / (14200) = (43) / (80)
To solve for x, we can cross-multiply and simplify:
80x = 14200 * 43
x = (14200 * 43) / 80
x ≈ 7632
Therefore, we can estimate that about 7632 people in the city have visited the city's community garden.
Three girls share R12000 in the ratio 2:3:7 calculate how much each girl will get show calculations
According to the ratio , the three girls shares are R2000,R3000 and R7000.
What is ratio?
When two numbers are compared, the ratio between them shows how often the first number contains the second. As an illustration, the ratio of oranges to lemons in a dish of fruit is 8:6 if there are 8 oranges and 6 lemons present.
Here the given total share amount is R12000.
Now the ratio for three girls is 2:3:7.

1. Hiro has 18 highlighters, which is 4 fewer than Martin has. How many markers
does Martin have?
what are the steps???
Answer:
Let's use algebra to solve this problem:
Let's use the variable "m" to represent the number of markers that Martin has.
We know that Hiro has 4 fewer highlighters than Martin, so we can set up an equation:
18 = m - 4
This equation says that the number of markers Martin has (m) minus 4 is equal to the number of highlighters that Hiro has (18).
To solve for "m", we can add 4 to both sides of the equation:
18 + 4 = m
Simplifying this gives us:
22 = m
So Martin has 22 markers.

Find the smallest possible value of x+y+z
The smallest possible value of x+y+z such that 3^x+5^y+7^z is divisible by 105 is 11.
What are Natural Numbers?Natural numbers are a set of positive integers that are used for counting and ordering. In other words, natural numbers are the set of numbers that are used to represent the quantity of objects, such as 1, 2, 3, 4, 5, 6, and so on. Some definitions include zero as a natural number, while others define natural numbers to start from 1. In mathematics, natural numbers are denoted by the symbol "N" or "N+", and are sometimes referred to as counting numbers.
What are whole numbers?Whole numbers are a set of non-negative integers that include all natural numbers (positive integers) and zero. Whole numbers are used to represent quantities that cannot be divided into smaller parts, such as the number of people in a room, the number of apples in a basket, or the number of books on a shelf.
In the given question,
We know that 105 is a multiple of 3, 5, and 7. Therefore, if 3^x+5^y+7^z is divisible by 105, it must also be divisible by 3, 5, and 7.
If 3^x+5^y+7^z is divisible by 3, then 3^x ≡ 0 (mod 3), which means x ≥ 1.
If 3^x+5^y+7^z is divisible by 5, then 5^y ≡ 0 (mod 5), which means y ≥ 1.
If 3^x+5^y+7^z is divisible by 7, then 7^z ≡ 0 (mod 7), which means z ≥ 1.
Therefore, we have x+y+z ≥ 3.
We also know that 105 is the smallest multiple of 3, 5, and 7. Therefore, we want to find the smallest values of x, y, and z that will make 3^x+5^y+7^z divisible by 105.
If we want 3^x+5^y+7^z to be divisible by 105, we need x, y, and z to be multiples of 4, 4, and 3, respectively.
The smallest such values are x=4, y=4, and z=3. Therefore, the smallest possible value of x+y+z is 4+4+3=11.
So, the smallest possible value of x+y+z such that 3^x+5^y+7^z is divisible by 105 is 11.

The recursive formula model to represent this situation is L(n) = L(n-1) + 5 where you can swim 15 laps every day.
What is recursive formula?A recursive formula is a formula that defines a sequence in terms of one or more of its preceding terms. In other words, it is a way to generate the terms of a sequence using the previous terms of the same sequence.
According to question:The given situation describes a sequence of numbers where each term is obtained by adding a fixed constant to the previous term. This is called an arithmetic sequence.In this case, we start with 15 laps swum in the first week, and then increase the distance by 5 laps each subsequent week. Let L(n) denote the number of laps swum in week n.To find the number of laps swum in week n, we can add 5 laps to the number of laps swum in week n-1, since the distance increases by 5 laps every week. This can be represented mathematically as:L(n) = L(n-1) + 5
where
L(n-1) represents the number of laps swum in the previous week.
The recursive formula above defines the arithmetic sequence that models the situation described in the problem.

The mean of the following data values is 36.
19, 23, 35, 41, 42
Answer:
To find the mean of a set of data, we need to sum up all the values in the set and divide by the number of values.
Sum of the data values = 19 + 23 + 35 + 41 + 42 = 160
Number of data values = 5
Mean = Sum of data values / Number of data values = 160 / 5 = 32
However, we are given that the mean is 36. Since the calculated mean is lower than the given mean, it means that we are missing a value that is higher than the other values in the set.
Let's call this missing value x. Then, we have:
(19 + 23 + 35 + 41 + 42 + x) / 6 = 36
Multiplying both sides by 6, we get:
19 + 23 + 35 + 41 + 42 + x = 216
Simplifying the left-hand side, we get:
160 + x = 216
Subtracting 160 from both sides, we get:
x = 56
Therefore, the missing value is 56, and the complete data set is:
19, 23, 35, 41, 42, 56
Now, we can calculate the mean as:
Mean = (19 + 23 + 35 + 41 + 42 + 56) / 6 = 216 / 6 = 36
So, the mean of the data values is indeed 36.
Answer:
32
Step-by-step explanation:
To find the mean of a set of numbers, we add up all the numbers and then divide by the total number of values.
Adding up the values:
19 + 23 + 35 + 41 + 42 = 160
We have a total of 5 values, so we divide the sum by 5:
160 / 5 = 32
Therefore, the mean of the given data values is 32, not 36.
