Answer:
If it takes one minute to use 5.7 calories, it’ll take 190/5.7 minutes to use 190 calories. This simplifies to 100/3 minutes. So this person must walk for 33 minutes and 20 seconds to use 190 calories (assuming the rate of calorie usage remains constant throughout).

Lisa wants to buy some new shirts at her favorite store. Each shirt costs $15 and she wants to buy a pair of shoes that are $35. Lisa only has $137 to spend.
Let S represent the number of shirts that Lisa buys.
Which inequality describes this scenario?
(A) 137> 15s +35
(B) 137< 15s +35
(C) 137≥ 15s +35
(D) 137≤ 15s +35
Considering the definition of an inequality, the correct answer is option (C): the inequality 15×S + 35≤ 137 describes the scenario.
Definition of inequalityAn inequality is the existing inequality between two algebraic expressions, connected through the signs:
greater than >.less than <.less than or equal to ≤.greater than or equal to ≥.An inequality contains one or more unknown values called unknowns.
Solving an inequality consists of finding all the values of the unknown for which the inequality relation holds.
Inequality in this caseIn this case, you know that
Each shirt costs $15.Lisa wants to buy a pair of shoes that are $35.Lisa only has $137 to spend.Being "S" the number of shirts that Lisa buys, the inequality that expresses the previous relationship is

Answer:add 5 and 4, you get 9. divide 54 by 9, and you get 6. this is because for every 5 sam gets bethan will get 4. if you add, that, you will get the total amount for 1 share.
Step-by-step explanation:
Answer:
Sam gets £30
Bethan gets £24
Step-by-step explanation:
Since they split the money in a ratio of 5:4, that means for every 5 parts of the money that Sam gets, Bethan gets 4 parts. The total of 5 parts and 4 parts is 9 parts.
To find how much each part is, we divide £54 by 9.
£54/9 = £6
Each part is £6.
Sam gets 5 parts: 5 × £6 = £30
Bethan gets 4 parts: 4 × £6 = £24

The length of a rectangular pool is three times its width. If the perimeter of the pool is one hundred and sixty meters, find the length and width of the pool.
Answer:
w = 20m
l = 60m
Step-by-step explanation:
P = 2l + 2w
We know the perimeter = 160 and we know that l = 3w, so write what we know and solve for w.
P = 2l x 2w
160 = 2(3w) + 2w
160 = 6w + 2w
160 = 8w
Divide both sides by 8
20 = w
Now we can figure out the length, which is 3(w) or 3 x 20 = 60

How many digits long could the repeating cycle of a repeating decimal be if the denominator of the rational number is 7?
A up to seven digits long
B up to six digits long
C any finite length
D infinitely long
Answer: a
Step-by-step explanation:
Every six powers of ten, the cycle repeats. In other words, a repeating decimal with a denominator of 7 can have a repeating cycle that is up to six digits long.
The repeating cycle of a repeating decimal for the rational number with a denominator of 7 can be determined by considering the factors of the denominator.
In this case, the denominator is 7, which is a prime number. The length of the repeating cycle can be determined by examining the powers of 10 modulo 7.
To find the length of the repeating cycle, we need to find the smallest positive integer "n" for which 10ⁿ - 1 is divisible by 7. In other words, we are looking for the smallest "n" such that 10ⁿ ≡ 1 (mod 7).
Let's calculate the powers of 10 modulo 7:
10¹ ≡ 3 (mod 7)
10² ≡ 2 (mod 7)
10³ ≡ 6 (mod 7)
10⁴ ≡ 4 (mod 7)
10⁵ ≡ 5 (mod 7)
10⁶ ≡ 1 (mod 7)
As you can see, the cycle repeats every 6 powers of 10. This means that the repeating cycle of a repeating decimal with a denominator of 7 can be up to six digits long.

The probability density of a random variable X is given in the figure below. The random variable is uniformly distributed between 0 and 2. From this density, find the probability that X is at least 0.48.
The probability that X is at least 0.48 given the information about the density of a random variable X is 0.76.
How to calculate the probability?Given that x is uniformly distributed between 0 and 2.
Therefore, the probability density function:
f(x)= 1 / (b-a) = 1 / (2-0)
= 0.5
This will be illustrated as:
P(X<=x)=(x-a)/(b-a)=(x-0)/(2-0)=x/2
Now, we have to find:
P(x >= 0.48)
= 1 - P(x<=1.68)
= 1-(0.48 / 2)

The sampling method used to get the sample is Systematic sampling.
The variable type of color of cars around the gym is qualitative.
Sampling is the process of choosing a subset of people (a statistical sample) from a statistical population in order to estimate characteristics of the entire population. It is used in statistics, quality control, and survey technique. Statisticians try to get samples that are typical of the population under consideration.
The different sampling methods used are:
Simple random sampling: Every member of the population has an equal probability of getting chosen.Systematic sampling : Members are chosen after a fixed interval every time.Stratified sampling: The entire population is divided into sub populations and then the sample is chosen from each sub population. Cluster sampling: The population is also divided into smaller groups for cluster sampling, although each smaller group should share traits with the larger sample. You choose complete subgroups at random rather than picking a representative sample of each subgroup.Now the given sample of the residents that were selected was every eighth car .
