Answer:
The Factor is 1.5
Step-by-step explanation:
5.1(which is B'C') divided by 3.4(which is BC) = 1.5
3.6(A'C') divided by divided by 2.4(AC) = 1.5
2.7(A'B') divided by 1.8(AB) = 1.5
Henceforth the factor is 1.5

5. While still in the hospital, the doctor writes an order for an antibiotic at 300mg/kg daily. You are nervous now because the nurse was wrong before. If you weigh 123 lb, determine how many milligrams you should be given.
The correct answer is 16737 mg
Explanation:
The first step to solve this problem is to convert the weight to kilograms because the dosage of the antibiotic is given in milligrams per kilo. This can be done by multiplying the pounds by 0.453 considering each pound is equal to 0.453 kilos. The process is shown below:
123 lb x 0.453 = 55.791 kg
Now, simply multiply the kilos by the recommended dose:
55.791 kg x 300 mg/kg = 16737 mg
Also, this can be converted to grams by dividing the number into 1000 (1000 mg = 1 g)
16737mg ÷ 1000 = 16.737 grames
Gabriella and her children went into a grocery store and where they sell apples for $1 each and mangos for $0.50 each. Gabriella has $15 to spend and must buy at least 19 apples and mangos altogether. If Gabriella decided to buy 13 mangos, determine the maximum number of apples that she could buy. If there are no possible solutions, submit an empty answer.
Answer:
She can buy a maximum of 8 apples.
Step-by-step explanation:
Let x represent the number of apples that she wants to buy.
The grocery store sells apples for $1 each and mangos for $0.50 each.
If Gabriella decided to buy 13 mangos, it means that the cost of buying x apples and 13 mangoes is expressed as
x + 13 × 0.5 = x + 6.5
If she buy at least 19 apples, it means that
x + 13 ≥ 19
x ≥ 19 - 13
x ≥ 6
Gabriella has $15 to spend. It means that
x + 6.5 ≤ 15
x ≤ 15 - 6.5
x ≤ 8.5
Therefore, the maximum number of apples that she can buy is 8
Answer:She would only be able to buy 8 more apples
Step-by-step explanation:
First you multiply 13 by .50 and you get 6.50
Next you subtract 6.50 from 15 and get 8.50
After that you see 1 dollar per apple so she can only get 8 apples for 8 dollars.
Therefore, she can only buy 8 more apples.
Extra:She can buy an extra mango with the leftover .50cent
The art teacher has 36 small sticks and 60 pipe cleaners for art projects. He wants to make kits for all the students using all the sticks and pipe cleaners. All the kits must be alike. He wants to make as many kits as possible. What is the greatest number of kits he can make.
A) 8 kits
B) 9 kits
C) 12 kits
D) 36 kits
Answer:
The greatest number of kits he can make is 12 kits
Step-by-step explanation:
The greatest common divisor or GCD is called the greatest number that divides exactly two or more numbers at the same time.
The greatest common divisor is usually expressed as GCD(a,b), where a and b are numbers.
Being the divisor of a number is the value that divides the number into exact parts, that is, that the remainder is zero, one way to calculate the GCD is to determine all the divisors of each number, and from these point out the common divisors, of which the major divisor will be the GCD of those numbers. In this case:
Divisors of 36: 1, 2, 3, 4, 6, 9, 12, 18, 36.
Divisors of 60: 1, 2, 3, 4, 5, 6, 10, 12, 15, 20, 30, 60.
The common divisors of 36 and 60 are 1, 2, 3, 4, 6 and 12, of which the greatest is 12. So GCD(36,60)=12
Another way to calculate the GCD is through prime factorization, which always starts with the smallest divisible number of the number being analyzed. In this case:
The decomposition of 36 is: 2*2*3*3 = 2²*3²
The decomposition of 60 is: 2*2*3*5= 2²*3*5
Now the common factors with the lowest exponent are chosen and multiplied. The result obtained is the GCD. In this case, the common factors of 36 and 60 are: 2² and 3 and their multiplication gives: 2²*3= 12. So GCD(36,60)=12
The greatest number of kits he can make is 12 kits

Increasing Interval: [-2, 1)
Decreasing Interval: (1, 4]
Constant Interval: [-4, -2)

Step-by-step explanation:
x-intercepts are where the function f(x) crosses the x-axis when y = 0.
y-intercepts are where the function f(x) crosses the y-axis when x = 0.
Increasing interval is the set of x-values in which the graph f(x) increases in y-value.
Decreasing interval is the set of x-values in which the graph f(x) decreases in y-value.
Constant interval is the set of x-values in which the graph f(x) y-values stay constant.
Maximum is the largest y-value function f(x) can output.
Minimum is the smallest y-value function f(x) can output.
Domain is the set of x-values that can be inputted into function f(x).
Range is the set of y-values that can be outputted from function f(x).
Sales at LL Boutique decreased 10% this month compared to last month. If sales this month were $103,581, what were the sales (in $) last month?
Answer:
Step-by-step explanation:
(103,581) • (%110)
= (103,581) • (1.10)
= $113,939.1
The sales (in $) last month were $115,090 if the sales at LL Boutique decreased 10% this month compared to last month. If sales this month were $103,581.
What is percentage?It's the ratio of two integers stated as a fraction of a hundred parts. It is a metric for comparing two sets of data, and it is expressed as a percentage using the percent symbol.
It is given that:
Sales at LL Boutique decreased 10% this month compared to last month. If sales this month were $103,581.
The arithmetic operation can be defined as the operation in which we do the addition of numbers, subtraction, multiplication, and division. It has a basic four operators that is +, -, ×, and ÷.
Let suppose x be the sales last month:
(x - 103581)/x = 0.1
x - 103581 = 0.1x
x - 0.1x = 103581
0.9x = 103581
x = 103581/0.9
x = $115,090
Thus, the sales (in $) last month were $115,090 if the sales at LL Boutique decreased 10% this month compared to last month. If sales this month were $103,581.

Which is the interquartile range for the city that has the greater variability in temperature?
Answer:
D. 40
Step-by-step explanation:
The greater the interquartile range of a data set, the greater the variability.
Interquartile range = third quarter (Q3) - first quartile (Q1)
Interquartile range of City A = 70 - 40 = 30
Interquartile range of City B = 80 - 40 = 40.
City B has a greater interquartile range than city A, therefore, City B has the greater variability in temperature, with an interquartile range of 40.
The temperature inside the lab refrigerator is at most 35 Fahrenheit used to represent the temperature in fahrenheit of the refrigerator
Complete question is;
Write inequalities to represent the situations below. The temperature inside the lab refrigerator is no more than 45 °F. Use t to represent the temperature (in °F) of the refrigerator.
Answer:
t ≤ 45 °F
Step-by-step explanation:
We are told to use t to represent the temperature (in °F) of the refrigerator.
We are also told that the temperature inside the lab refrigerator is no more than 45 °F.
For the temperature inside the refrigerator to be no more than 45 °F, it means the temperature should be either less than or equal to 45 °F
Thus means that t is less than or equal to 45 °F.
Thus, it can be represented in terms of inequality as;
t ≤ 45 °F
Answer:
t ≤ 35

The sale price of a spring break vacation package was $209.99 the travel agent said by booking early you saved $20.00. Find the percent decrease in price
Answer:
[tex]\%\ decrease = 9.52\%[/tex]
Step-by-step explanation:
Given
[tex]Sales\ Price = \$209.99[/tex]
[tex]Saved = \$20.00[/tex]
Required
Determine the %decrease
First, we need to determine the amount paid
[tex]Amount = Sales\ Price - Amount\ Saved[/tex]
[tex]Amount = \$209.99 - \$20.00[/tex]
[tex]Amount = \$189.99[/tex]
The percentage decrease is the calculated as follows:
[tex]\%\ decrease = -100\% * \frac{Final - Initial}{Initial}[/tex]
In this case;
[tex]Initial = Sales\ Price = \$209.99[/tex]
[tex]Final = Amount\ Paid = \$189.99[/tex]
So; we have:
[tex]\%\ decrease = -100\% * \frac{189.99 - 209.99}{209.99}[/tex]
[tex]\%\ decrease = -100\% * \frac{-20}{209.99}[/tex]
[tex]\%\ decrease = 100\% * \frac{20}{209.99}[/tex]
[tex]\%\ decrease = \frac{2000\%}{209.99}[/tex]
[tex]\%\ decrease = 9.52426306015\%[/tex]

Find the points of intersection (if any) of the graphs of the equations. Use a graphing utility to check your results. y = - x + 4, y = 4x - 2
Answer:
[tex]x = 1.2[/tex]
See Attachment for Graph
Step-by-step explanation:
Given
[tex]y = -x + 4[/tex]
[tex]y = 4x - 2[/tex]
Required
Determine the point of intersection
To do this, we simply equate both expressions of y
i.e.
[tex]-x + 4 = 4x - 2[/tex]
Solve for x
[tex]-x - 4x = - 2 - 4[/tex]
[tex]-5x = -6[/tex]
Divide through by -5
[tex]x = \frac{-6}{-5}[/tex]
[tex]x = \frac{6}{5}[/tex]
[tex]x = 1.2[/tex]
Hence, the point of intersection is 1.2
