Answer:
17Step-by-step explanation:
k/8 + 12 (Twelve more means add 12, quotient means divide, and number is k)
Now, if we replace k with 40, we get:
40/8 + 12
5 + 12 = 17
Twelve more (+ 12) than the quotient (dividing) of a number and eight
k/8 + 12
k = 40
40/8 + 12
5 + 12 = 17
Therefore, the value of the expression when k = 40 is 17.

Anthony decided to buy two DVDs that were not included in the deal. His price before tax was $19.99. What was the cost of the two DVDs after the 8.25% tax was added?
Given:
Cost of 2 DVDs before tax = $19.99
Tax rate = 8.25%
To find:
The cost of 2 DVDs after the tax was added.
Solution:
We have,
Cost of 2 DVDs before tax = $19.99
Tax rate = 8.25%
So,
Tax = 8.25% of Cost of 2 DVDs before tax
[tex]Tax=\dfrac{8.25}{100}\times 19.99[/tex]
[tex]Tax=1.649175[/tex]
[tex]Tax\approx 1.65[/tex]
Now,
Cost of 2 DVDs after tax = Cost of 2 DVDs before tax + Tax
= $19.99 + $1.65
= $21.64
Therefore, the cost of 2 DVDs after the tax is $21.64.
It takes 5 cups of oil to make a dozen brownies. How much will I need to make 36 brownies.
Answer:
15 cups
Step-by-step explanation:
A dozen = 12, and 36 is 3 dozen! If you divide 36 by 12 you get 3, which you multiply by 5 to find your total amount of oil.
The average mass of 4 boys is 45 kg. When a fifth boy joins them the average mass changes to 40 kg. What is the mass of the fifth boy?
Answer:
If the average mass of 4 boys is 45, that means that the sum of all buys divided by the quantity of them (4) is 45, so if we want to calculate the sum of their masses, we can solve this equation:
[tex]\frac{x}{4} = 45[/tex]
Then, we pass the 4 multiplying:
[tex]x = 45*4 = 180[/tex], so we know the four boys that were taken into account on thatt average sum 180 kg of mass
Now, if another boy joins with a mass of x, we can add it to the mass we gott and, as we know dividing that by 5 will give us 40, we solve the equation:
[tex]\frac{180+x}{5} = 40[/tex]
We pass the five multiplying:
[tex]180 + x = 40 * 5[/tex]
[tex]180 + x = 200[/tex]
[tex]x = 20[/tex]
Now we know that the fith of these boys has a mass of 20 kg
The mass of the fifth boy is given as 20 kg.
How to find the mean and median for a given sample of data?In order to find the mean, first sum all the values of the data and count the number of data then divide them. It is also known as average.
In order to find the median, first check whether the number of data is even or odd. For even number, the median is n/2 th element of the sample and for odd number the median is (n + 1)/2 th element.
Given that,
The average mass of 4 boys is 45 kg.
And, the average mass of 5 boys is 40 kg.
Suppose the mass of fifth boy be x kg.
The total mass of 4 boys is given as,
Average of mass of 4 boys × 4
= 45 × 4
= 180
Total mass of 5 boys = Average of mass of 5 boys × 5
=> 180 + x = 5 × 40
=> x = 20
Hence, the mass of the fifth boy is 20 kg.

A pizza shop offers a large cheese pizza for $14. Each additional topping is $1.5. The price of a large pizza can be modeled with the function
P(t) = 14 + 1.5t
where t is the number of toppings.
What is P(4), and what does that mean in the context of the story?
We have the following:
[tex]p(t) = 14+1.5t[/tex]
t is the number of toppings
Now, t=4
Replacing:
[tex]p(t)=14+1.5 .4\\p(t) =14+6\\p(t)=20[/tex]

In a sample of 1000 U.S. adults, 198 think that most celebrities are good role models. Two U.S. adults are selected from this sample without replacement. Complete parts (a) through (c).
(a) Find the probability that both adults think most celebrities are good role models.
The probability that both adults think most celebrities are good role models is
(Round to three decimal places as needed.)
(b) Find the probability that neither adult thinks most celebrities are good role models.
The probability that neither adult thinks most celebrities are good role models is

(C) Find the probability that at least one of the two adults thinks most celebrities are good role models.
The probability that at least one of the two adults thinks most celebrities are good role models is
(Round to three decimal places as needed.)
The probability that at least one of the two adults believes most famous people make good role models be 0.436.
What is meant by probability?A probability is a number that expresses the possibility or likelihood that a specific event will take place. Probabilities can be stated as proportions with a range of 0 to 1, or as percentages with a range of 0% to 100%.
A) The likelihood that both adults believe that most famous people make good role models would be = (199/800) × (198/799) = 39402/639200 = 0.062
B) We're looking for the likelihood that neither adult believes that most famous people make good role models.
Today that 199 people out of 800 believe that most famous people make decent role models.
The percentage of people who disagree that most celebrities make for good role models = 800 - 199 = 601
The probability that neither adult thinks most celebrities exists good role models. would be = (601/800) × (600/799)= 180300/319600 = 0.564
C) We're looking for the likelihood that at least one of the two adults believes that most celebrities make for positive role models.
Now that we know that neither of them believes that the majority of famous people are good role models, we can simply deduct that probability from 1.
The likelihood that at least one of the two adults believes most famous people make good role models = 1 - 0.564 = 0.436

Step-by-step explanation:
You've got the initial temperature down: the constant that the function multiplies is the initial condition/number/temperature/population/&tc. since that constant is 19, the initial temperature is 19° C.
However, this is not an exponential growth function. This is an exponential decay function. There are two ways to surmise this:
The context of the problem is a soda can placed in a cooler. The temperature will decrease, right? This means the function is an exponential decay function.If the function given were an exponential growth function, then the number within parentheses (this is the percentage by which something changes) would be greater than 1. It isn't, and so the function is an exponential decay functionAs for the percentage at which it is changing… erm, decreasing… that would be 100 times the difference of 1 – r. Here, r is the number in parentheses. First, let's solve for 1 – r. Here, r is 0.89, so 1 – 0.89 = 0.11, and now we just need to multiply by 100. Why?
Percentages are a fraction of 100. For example, 89% is equal to 0.89 and the fraction [tex]\frac{89}{100}[/tex]. Here, we multiply 0.11 to find the percentage of change. So we have 0.11 × 100 = 11%, and our rate of change is 11%. Thanks to breyanamyers5 who indirectly hinted at my mistake here!

You bike 11.2 miles in 1.4 hours at a steady rate. What equation represents the proportional relationship between the x hours you bike and the distance y in miles that you travel?
Answer:
x/y = 8 or 8x
Step-by-step explanation:
Step-by-step explanation:
Let the time for which i bike is = x hours
Let the distance traveled in x hours = y miles
Ratio of distance and time will be = x : y
I travel 11.2 miles in 1.4 hours then the ratio of time and the distance traveled will be 1.4 : 11.2 Or 14 : 112
then the ratio of distance and time will be same in both the cases.
