To make 20 cups of Jessica's favorite purple paint, she needs approximately 6.67 cups of blue paint and 10 cups of red paint.
Explanation:To find the number of cups of blue and red paint Jessica needs to make 20 cups of her favorite purple paint, we need to set up a proportion based on the ratios of blue paint and red paint in her favorite shade.
Since Jessica uses 1/3 cup of blue paint and 1/2 cup of red paint to make her favorite shade, we can set up the proportion:
1/3 cup of blue paint / 1/2 cup of red paint = x cups of blue paint / 20 cups of purple paint.
To solve for x, we can cross multiply and divide:
x = (1/3 cup of blue paint)(20 cups of purple paint) / (1/2 cup of red paint) = 20/3 = 6.67 cups of blue paint.
So, Jessica needs approximately 6.67 cups of blue paint and 10 cups of red paint to make 20 cups of her favorite purple paint.

find the value of the polygon. the polygon has 6 interior angles 2 of them are y and 4 of them are (2Y-20)
in order for RECT to be a rectangle, what must the value of x be?
Answer:
x = 21
Step-by-step explanation:
If RECT is a rectangle, each of its interior angles are right angles, 90°. Since ∠RTC is split into two angles, the sum of the two angles must be 90°. (Angles that add to 90° are called complementary angles).
∠RTC = ∠RTE + ∠ETC Formula for complementary angles
90 = 2x + 6 + 42 Substitute the angles
90 = 2x + 48 Combined like terms to simplify
Now isolate "x" to solve
90 - 48 = 2x + 48 - 48 Subtract 48 from both sides
42 = 2x
42/2 = 2x/2 Divide both sides by 2
x = 21
Therefore x is 21.

A company makes boxes of cereal. A box usually contains 450 grams of cereal. Here are two options for a special offer. Option A 20% more cereal Option B usual amount of cereal 15% off the price.
Which option is best for the customer
A percentage is a way to describe a part of a whole. The best option for the customer to buy is option A.
What are Percentages?A percentage is a way to describe a part of a whole. such as the fraction ¼ can be described as 0.25 which is equal to 25%.
Let the cost price of a cereal box be represented by x.
Given that the box usually contains 450 grams of cereal. Therefore, the unit rate for each option can be written as,
Option A
Weight of cereal = 20% more cereal
= 450 grams + 20% of 450 grams
= 450 grams + 90 grams
= 540 grams
Unit rate for option A = $x / 540 grams
Option B
Cost price of cereal = 15% off the price
= x - 15% of x
= x + 0.15x
= 0.85x
Unit rate for option A = $0.85x / 450 grams
Assume that option A is good. Now, if we subtract unit rate of option B from unit rate of option A then two of the cases are possible, if the value of the result is positive then the unit rate of option A is bigger while if the value is negative unit rate of option B is bigger.
Difference = (x/540) - (0.85x/450)
= (450x - 459x)/243000
= -9x/243,000
= -x/27,000
Further, since the difference is negative, therefore, the unit rate of option B is bigger. But since the value of option B is bigger it is costly and not the correct option to buy.
Hence, the best option for the customer to buy is option A.

An adult meerkat weighs 776 grams. This is o.747 kilograms more than the weight of a baby meerkat. how much does a baby meerkat weigh ?
The baby meerkat weighs 29 grams.
First, we need to ensure our units are the same, so we'll convert 776 grams to kilograms.
There are 1,000 grams in a kilogram, so 776 grams is equivalent to 0.776 kilograms.
Given that the adult meerkat is 0.747 kilograms heavier than the baby meerkat, we can calculate the baby meerkat's weight by subtracting.
Baby meerkat weight = Adult meerkat weight - Additional weight
Baby meerkat weight = 0.776 kg - 0.747 kg
Baby meerkat weight = 0.029 kg
To express this in grams, we multiply by 1,000:
Baby meerkat weight in grams = 0.029 kg × 1000
= 29 grams
Maya has 5 over 6 cup of ice cream. how many 1 over 4-cup servings are in 5 over 6 cup of ice cream?
there are [tex]\( \frac{10}{3} \) or \( 3 \frac{1}{3} \) servings of \( \frac{1}{4} \)-cup in \( \frac{5}{6} \)[/tex] cup of ice cream.
To find out how many [tex]\( \frac{1}{4} \)-cup servings are in \( \frac{5}{6} \)[/tex] cup of ice cream, we need to divide [tex]\( \frac{5}{6} \) by \( \frac{1}{4} \)[/tex].
We can do this by converting [tex]\( \frac{5}{6} \)[/tex] to have the same denominator as [tex]\( \frac{1}{4} \)[/tex], which is 6, and then dividing:
[tex]\[ \frac{5}{6} \div \frac{1}{4} \][/tex]
To make the denominators the same, we multiply both the numerator and denominator of [tex]\( \frac{5}{6} \) by \( 4 \):[/tex]
[tex]\[ \frac{5 \times 4}{6 \times 4} \div \frac{1}{4} \][/tex]
[tex]\[ = \frac{20}{24} \div \frac{1}{4} \][/tex]
Now, we can divide [tex]\( \frac{20}{24} \) by \( \frac{1}{4} \):[/tex]
[tex]\[ \frac{20}{24} \div \frac{1}{4} \][/tex]
[tex]\[ = \frac{20}{24} \times \frac{4}{1} \][/tex]
[tex]\[ = \frac{20 \times 4}{24 \times 1} \][/tex]
[tex]\[ = \frac{80}{24} \][/tex]
Now, we simplify the fraction:
[tex]\[ \frac{80}{24} = \frac{10 \times 8}{12 \times 2} \][/tex]
[tex]\[ = \frac{10}{3} \][/tex]
Therefore, there are [tex]\( \frac{10}{3} \) or \( 3 \frac{1}{3} \) servings of \( \frac{1}{4} \)-cup in \( \frac{5}{6} \)[/tex] cup of ice cream.

The probability that an airplane flight departs on time is 0.89 The probability that a flight arrives on time is 0.87 The probability that a flight departs and arrives on time is 0.81
To answer the questions, we need to use the concepts of probability.
Explanation:To answer the questions, we need to use the concepts of probability.
a. The number of airplanes arrive and depart the airport per hour can be calculated by multiplying the probabilities of a flight departing and arriving on time. Although the exact numbers are not given, the probability of a flight departing and arriving on time is 0.81, which can be used as an estimate.
b. To find the probability that there are exactly 100 arrivals and departures in one hour, we need to use the concept of the binomial distribution. However, we don't have enough information to calculate the probability.
c. To find the probability that there are at most 100 arrivals and departures in one hour, we can use the concept of the cumulative distribution function of the binomial distribution. Again, we don't have enough information to calculate the probability.
The question is about calculating probabilities and involves understanding conditional probability, probability distributions, and statistical methods. It requires more data to answer parts a, b, and c. The remaining parts of the question can be approached with standard statistical methods and concepts.
Explanation:The question pertains to the field of probability within mathematics and involves calculations based on given probabilities for airplane flights departing and arriving on time. The data presented involve conditional probabilities and the characteristics of certain probability distributions. It is essential to understand these concepts to solve the exercises provided. Unfortunately, the given information does not contain sufficient details to answer parts a, b, and c as they require additional specific data about the actual number of flights or arrivals and departures per hour. However, the remaining parts of the question can be approached with standard statistical methods such as using z-scores for normal distributions, applying properties of uniform distributions for waiting times, understanding the concept of rate-determining steps in a process, and conducting hypothesis tests about a population mean given a sample.

solve 12^x-2=20 round to the nearest ten-thousandth? help, please!
The solution to the equation 12^x - 2 = 20, when solved for x and rounded to the nearest ten-thousandth, is x = 1.4624.
Explanation:To solve the equation 12^x - 2 = 20, we first need to isolate the exponential term. This can be done by adding 2 to both sides of the equation resulting in 12^x = 22. Next, we take the logarithm of both sides to solve for x. We can use any logarithmic base, but common practice is to use base 10 or the natural logarithm (base e). The next steps are:
Take the logarithm of both sides: log(12^x) = log(22).Apply the exponent rule of logarithms: x · log(12) = log(22).Divide both sides by log(12) to solve for x: x = log(22) / log(12).Use a calculator to find the value of x and round to the nearest ten-thousandth.Calculating the value on a calculator gives us x ≈ 1.4624. Therefore, the solution to the equation, rounded to the nearest ten-thousandth, is x = 1.4624.
The correct answer is option (b) "x ≈ 1.2056."
To solve the equation [tex]\(12^{(x-2)} = 20\)[/tex], we can take the logarithm of both sides.
Let's use the natural logarithm (ln) for this:
[tex]\[ \ln(12^{(x-2)}) = \ln(20) \][/tex]
Using the logarithm property [tex]\( \log_a(b^c) = c \cdot \log_a(b) \)[/tex], we can rewrite the left side:
[tex]\[ (x-2) \cdot \ln(12) = \ln(20) \][/tex]
Now, solve for (x):
[tex]\begin{aligned}& x-2=\frac{\ln (20)}{\ln (12)} \\& x=\frac{\ln (20)}{\ln (12)}+2\end{aligned}[/tex]
Now, calculate the value:
[tex]\begin{aligned}& x \approx \frac{\ln (20)}{\ln (12)}+2 \\& x \approx \frac{2.9957}{2.4849}+2 \\& x \approx 1.2056\end{aligned}[/tex]
So, the solution to the equation is approximately [tex]\( x \approx 1.2056 \)[/tex]
Complete Question:
Solve [tex]\(12^{(x-2)} = 20\)[/tex]. Round to the nearest ten-thousandth.
a. x ≈ 1.0792
b. x ≈ 1.2056
c. x ≈ 3.2056
d. x ≈ 1.3010
Shane and his family go to the movie theatre and buys 6 tickets for $12 each. then they spend a total of $31 for popcorn and drinks. how much did shane and his family spend for tickets, popcorn, and drinks at the movie theatre?
Shane and his family spent a total of $103 at the movie theatre, which includes the cost of 6 tickets at $12 each and $31 on popcorn and drinks.
Explanation:Shane and his family bought 6 tickets for $12 each, thus the total cost of the tickets is 6 * $12 which equals $72. Afterwards, they spent an additional $31 on popcorn and drinks. To find out how much they spent altogether at the movie theatre, we have to add the cost of the tickets and the cost of the popcorn and drinks. Therefore, $72 (for the tickets) + $31 (for the snacks) = $103. So, Shane and his family spent a total of $103 at the movie theatre.
