TrueAny number take away zero, is still that number.
The sum of two numbers is 54. The sum of the smaller and 5 times the larger is 166. Find the numbers.
Answer:
smaller number is 26
larger number is 28
Step-by-step explanation:
This is a system of equations that we can solve by substitution. Let x = the smaller number and y the larger. The two equations are:
x + y = 54
x + 5y = 166
Solve the first equation for y and use that in the second equation.
y = 54 - x (we will plug this in for y in the second equation and solve that for x)
x + 5(54 - x) = 166
x + 270 - 5x = 166
-4x = 166 - 270
-4x = -104
x = 26
Plug this into x + y = 54 and solve for y
26 + y = 54
y = 54 - 26
y = 28

Answer:
Step-by-step explanation:
Plug in 6 for x for g(x) and f(x)
f(6) = 2(6)⁵ = 15,552
g(6) = 10 x 4⁶ = 40,960
15,552 < 40,960
f(6) < g(6)
The graph of the absolute value parent function, f(x) = |x|, is stretched horizontally by a factor of 6 to create the graph of g(x). What function is g(x)?
A. g(x) = |6x|
B. g(x) = |x + 6|
C. g(x) = |⅙x|
D. g(x) = 6|x|
Answer:
C
Step-by-step explanation:
To stretched f(x) = |x| horizontally by a factor of 6, and create the graph of g(x) we have to divide the value of x by 6 so the y values for g(x) will be lower then the y values for f(x).

If the relationship is proportional, how many students would there be in a school with 32 teachers? Show your dimensional analysis
The number of students would there be in a school with 32 teachers is 32k.
What is meant by proportionality?In general, proportion refers to a part, share, or amount considered in comparison to a whole. According to the definition of proportion, two ratios are in proportion when they are equivalent. It is a formula or statement that shows that two ratios as well as fractions are equal.A proportion formula is just an equation that may be solved to determine the values to compare. We use the concept of proportion to solve proportion problems, which is two ratios that really are equal to each other.As the number of students are proportional to number of teachers.
Thus,
students ∝ teachers
student ∝ 32
students = 32k
where, k is the constant of proportionality.
Thus, the total number of students will be 32 k.

t-shirts will be sold for $6.00 each. Write a model for
cost C(x) and revenue R(x). How many t-shirts
must be sold to break even? (3 pts)
The function of cost is C(x) = 3.50x + 2000 and revenue is R(x) = 6x and 800 t-shirts must be sold to break even.
To find the linear value perform, begin from the slope-intercept kind C(x) = mx + b wherever x is the number of T-shirts and C(x) is that the value to supply those T-shirts. we'd like to search out the slope"m" and also the intercept "b".The cost is differently of touching on the slope of the value perform. this suggests that
m = 3.50 and b = 2000 swing this into the value perform, we have
C(x) = 3.50x + 2000
Revenue function = selling price × number of shirt
R(x) = 6x
The break-even purpose is found by setting the value perform C(x) adequate to the revenue perform R(x) .
C(x) = R(x)

Interpret the quote in terms of what you have learned about essential and discretionary vacation expenses.
The interpretation of the above quotation in terms of what is essential and discretionary vacation expenses implies that there are some unnecessary vacation expenses while others are compulsory vacation expenses.
What are discretionary and nondiscretionary expenses?
Discretionary expenses refer to outflows that a person can avoid if they choose.
On the other hand, one cannot avoid nondiscretionary expenses after choosing a spending activity because they are necessary and compulsory.
An example of nondiscretionary expenses are taxes, the cost of meals, and utility expenses. An example of a discretionary outflow is charitable donations.
Thus, when Robert Louis Stevenson claims that he travels for travel's sake, not to achieve any purpose, the expenses he incurs on such a trip are discretionary. He can avoid them by choosing not to embark on vacations.

Laura, Aldo, and Juan served a total of 95 orders Monday at the school cafeteria. Juan served 2 times as many orders as Laura. Aldo served 7 more orders than Laura. How many orders did they each serve?
the orders served by Laura are 22, the orders served by Aldo are 29 and the orders served by Juan are 44.
Total number of orders served on Monday at the school cafeteria = 95
Juan served 2 times as many orders as Laura and Aldo served 7 more orders than Laura.
Let the orders served by Laura be x
Orders served by Juan = 2 x
Orders served by Aldo = x + 7
So, we get the equation as:
x + 2 x + x + 7 = 95
4 x + 7 = 95
4 x = 95 - 7
4 x = 88
x = 88 / 4
x = 22
x + 7 = 22 + 7 = 29
2 x = 2 (22) = 44
Therefore, we get that, the orders served by Laura are 22, the orders served by Aldo are 29 and the orders served by Juan are 44.

A real estate agent works on 11% commission. What is her commission on house that she sold $346,000?
A real estate agent commission on the house that she sold $346,000 is $38,060.
Given that, a real estate agent works on 11% commission.
We need to find out what is her commission on the house that she sold $346,000.
What is the commission?The commission is a percentage of total sales as determined by the rate of commission. Commission=Rate of commission⋅Total sales. To find the commission on a sale, multiply the rate of commission by the total sales.
Now, the commission on the house=11% of 346,000
=11/100 × 346,000
=0.11 × 346,000
=$38,060

Evaluate the expression when c=5 and d=42 d-6c
The value of the expression when c = 5 and d = 42 is 12
How to evaluate the expression?The given parameters are:
c = 5 and d = 42
The expression is given as:
d - 6c
To evaluate the expression when c = 5 and d = 42, we substitute c = 5 and d = 42 in expression d - 6c
This is represented as
d - 6c = 42 - 6 * 5
Evaluate the product in the above expression
So, we have
d - 6c = 42 - 30
Evaluate the difference in the above expression
So, we have

What is referred as the unitary method?The unitary method is a process that determines the value of a specific unit from the value of multiple units, as well as the value of multiple units from of the value of a single unit.We must first divide to find the value of one thing, and then multiply to determine the value of much more or fewer things.Now, for the given question;
The cost of 3 pounds of shrimp at Earl's shrimp hut = $38.25.
3 pounds ---------> $38.25
Divide both sides by 3.
1 pound ------------>$12.75
Multiply 12 on both side;
12 pounds -------------> $153.
The cost of 4 pounds of shrimp at shrimpie's for 50.00.
4 pounds ---------> $50.00.
Divide both sides by 4.
1 pound ------------>$12.5
Multiply 12 on both side;
12 pounds -------------> $150.
Cost difference = Earl's shrimp hut - shrimpie
Cost difference = $153 - $150 = $3.

Quartile deviation in Statistics can be defined as the statistic that measures the dispersion. Here, the Dispersion is the state of getting dispersed or spread. Statistical dispersion means the extent to which numerical data is likely to vary about an average value. In other words, dispersion helps to understand the distribution of the data Suppose Q1 is the lower quartile, Q2 is the median, and Q3 is the upper quartile for the given data set, then its quartile deviation can be calculated using the following formula.
QD = (Q3 – Q1)/2
In the next section, you will learn how to calculate these quartiles for both ungrouped and grouped data separately.
For an ungrouped data, quartiles can be obtained using the following formulas,
Q1 = [(n+1)/4]th item
Q2 = [(n+1)/2]th item
Q3 = [3(n+1)/4]th item
Where n represents the total number of observations in the given data set.
Also, Q2 is the median of the given data set, Q1 is the median of the lower half of the data set and Q3 is the median of the upper half of the data set.
