9:7 is the ratio of crayons to colored pencils.
What is the ratio?The ratio can be defined as the number that can be used to represent one quantity as a percentage of another. Only when the two numbers in a ratio have the same unit can they be compared. Ratios are used to compare two objects.
The ratio of crayons to colored pencils can be found by dividing the number of crayons by the number of colored pencils:
The ratio of crayons to colored pencils = 27/21
Simplifying this ratio by dividing both the numerator and denominator by 3, we get:
The ratio of crayons to colored pencils = 9/7
Therefore, the ratio of crayons to colored pencils is 9:7.

Step-by-step explanation:
When formulating a constraint, care must be taken to ensure that a. all the objective function coefficients are included. b. the decision variables are set at either maximum or minimum values. c. the units of measurement on both sides of the constraint match. d. there are no inequalities in the mathematical expression.
Answer: C. the units of measurement on both sides of the constraint match.
Step-by-step explanation:
A constraint simply refers to the condition with regards to an optimization problem which must be satisfied by the solution.
When formulating a constraint, care must be taken to ensure that the units of measurement on both sides of the constraint match.
It should be noted that it's not necessary for all the objective function coefficients to be included. Also, there must be inequalities in the expression. Therefore, the correct option is C.
Bryce, a top landscape architect, was given a special garden design job. The client owned a property as shown below, in which he wanted to have four separate small gardens, each of them exactly the same size and shape. In other words, “congruent.” Remember, all four gardens must fit exactly within the shape of the property as shown below; you can’t change the dimensions of the property or move things around - you have to keep your design within the original shape. Bryce came up with an ingenious design that fit the client’s request exactly. Can you figure out what his design was?

[tex]H - 2 = 2 * (B -2)[/tex]
Required
H and B
We have:
[tex]H - 2 = 2 * (B -2)[/tex]
Open bracket
[tex]H -2 =2B - 4[/tex]
Add 2 to both sides
[tex]H -2+2 =2B - 4+2[/tex]
[tex]H =2B -2[/tex]
Substitute [tex]H = B + 7[/tex]
[tex]B + 7 =2B -2[/tex]
Collect like terms
[tex]2B - B =7+2[/tex]
[tex]B = 9[/tex]
Substitute [tex]B = 9[/tex] in [tex]H = B + 7[/tex]
[tex]H = B + 7[/tex]
[tex]H = 9 + 7[/tex]

Grumpy Corp drug tests all of the recent college graduates it hires each year. The drug test currently used correctly determines drug users 96% of the time(a Positive test) and correctly determines non-users 90% of the time(a Negative test). A recent study concluded that 36% of college students use drugs. A potential employee has been tested and the result was Negative for drug use.
Required:
a. Construct ALL necessary probabilities using proper notation(Example: P(D) for a "drug user").
b. Find the Probability of a Negative test, by showing use of the above Probabilities first, and then followed by the proper calculation.
Answer:
Hence, the probability of a Negative test is [tex]P(T^C)=0.5904[/tex].
Step-by-step explanation:
(a)
Let [tex]D=[/tex] Drug user and [tex]T=[/tex] Test positive
Probability of drug users [tex]P(D)=36\%=0.36[/tex]
[tex]P(\frac{T}{D})=96\%=0.96[/tex]
[tex]P(\frac{T^c}{D^c})=90\%=0.90[/tex]
(b)
Find the Probability of a Negative test,
[tex]P(T^C)=P(\frac{T^C}{D^C})\cdot P(D^C)+P(\frac{T^C}{D})\cdot P(D)[/tex]
[tex]\Rightarrow P(T^C)=0.9\cdot(1-0.36)+(1-0.96)\cdot 0.36[/tex]
[tex]\Rightarrow P(T^C)=0.9\cdot 0.64+0.04\cdot 0.36[/tex]
[tex]\Rightarrow P(T^C)=0.576+0.0144[/tex]
[tex]\Rightarrow P(T^C)=0.5904[/tex]

Answer:
72.22 inches
Step-by-step explanation:
Okay so the formula for circumference is C=2πr so since the diameter is twice the radius, the radius is 11.5. Now you have to multiply 11.5 and 2. That equals 23. Now you have to multiply 23 by π which is about 3.14. 23 times 3.14 is 72.22 inches.

Aaron was offered a job that paid a salary of \$57,000$57,000 in its first year. The salary was set to increase by 1% per year every year. If Aaron worked at the job for 29 years, what was the total amount of money earned over the 29 years, to the nearest whole number?
Answer:
The total amount received is: $1906650
Step-by-step explanation:
Given
[tex]a = \$57000[/tex] --- initial
[tex]b = 1\%[/tex] --- rate
[tex]n = 29[/tex] --- time
Required
Determine the total amount at the end of 29 years
The given question is an illustration of geometric progression, and we are to solve for the sum of the first n terms
Where [tex]n = 29[/tex]
[tex]r = 1 + b[/tex]
[tex]r = 1 + 1\%[/tex]
Express percentage as decimal
[tex]r = 1 + 0.01[/tex]
[tex]r = 1.01[/tex]
The required is the calculated using:
[tex]S_n = \frac{a(r^n - 1)}{r - 1}[/tex]
So, we have:
[tex]S_n = \frac{57000 * (1.01^{29} - 1)}{1.01 - 1}[/tex]
[tex]S_n = \frac{57000 * (1.3345- 1)}{0.01}[/tex]
[tex]S_n = \frac{57000 * 0.3345}{0.01}[/tex]
[tex]S_n = \frac{19066.5}{0.01}[/tex]
[tex]S_n = 1906650[/tex]
The total amount received is: $1906650

sale committee wants to raise $186 for a donation to a local charity they set a size $12 of their profit at the end of each day how many days will it take them to raise enough money for the whole donation
Answer:
15 and a half days
Step-by-step explanation:
Since they earn $12's each day you would do $186 divided by $12 which would be 15.5 so it would take them 15 and a half days to raise $186.
Answer:
Sorry if this is late, but I hope you understand now.
Step-by-step explanation:
It's 16 days actually, if you divide 186 divided by 12, it's 15.5 we can say, that 5 should be rounded up or down. 15.5 is a fraction of 15/5 so if we rounded it, it would be 16. That's our newer version of rounding. 5 is higher, 4 is lower. Use that to help you :) I hope you understand even though it late

10) 29%
Help
Answer:
[tex](a) 78.4\% = 0.784[/tex]
[tex](b) 29\% =0.290[/tex]
Step-by-step explanation:
Required
As a decimal to nearest thousandth
Solving (a): 78.4%
[tex]78.4\%[/tex]
Express as fraction
[tex]78.4\% = \frac{78.4}{100}[/tex]
Solve fraction
[tex]78.4\% = 0.784[/tex] ----- This is already in thousandth place
Solving (b): 29%

the results of rolling a single die are shown in a table below. find the experimental probability of rolling a 5
number total
1 12
2 16
3 21
4 23
5 18
6 10
Answer:
1/12
Step-by-step explanation:
To find experimental probability you have to solve the Number of times an event occurs / Total number of trials. So since the 5 only appears once and there are 12 numbers, it would be 1/12. Did this help?
The experimental probability of rolling 5 will be 0.18.
What is probability?Its fundamental concept is that someone will nearly surely occur. The proportion of positive events in comparison to the total of occurrences. Then the probability is given as,
P = (Favorable event) / (Total event)
The table is given below:
Number Total
1 12
2 16
3 21
4 23
5 18
6 10
The experimental probability of rolling a 5 is calculated as,
P = 18 / (12 + 16 + 21 + 23 + 18 + 10)
P = 18 / 100
P = 0.18
Thus, the probability is 0.18.

A circle has a circumference of 113.04 units.
Answer:
The answer may or may not be either the diameter is 36 units, or the radius is 18 units.
Step-by-step explanation:
Since there is no question, then I am just assuming the question is what is the diameter or the radius. You would find this by dividing the circumference by pi:
113.04 / 3.14 = the diameter is 36
36 / 2 = the radius is 18
