at a hot dog stand they serve regular and footlong hot dogs at a ratio of 5 to 3 based on this ratio how many footlongs hot dogs will be served there is a total of 120 hot dogs served. A. 45 footlong hot dogs, B. 75 footlong hot dogs, C. 72 footlong hot dogs
Answer:
45
Step-by-step explanation:
Ratio is 5:3
So total ratio "parts" is 5 + 3 = 8
In total there are 120 dogs served, so each part is:
120/8 = 15 dogs
Since, footlong hot dogs are "3" parts, and each part is 15 dogs, there will be:
3 * 15 = 45 footlong hotdogs
Answer:
45

The number of visits to public libraries increased from 1.3 billion in 1998 to 1.5 billion in 2002. Find the average rate of change in the number of public library visits from 1998 to 2002.
Answer:
A = 0.05 billion visits per year
Step-by-step explanation:
Given that,
The number of visits to public libraries increased from 1.3 billion in 1998 to 1.5 billion in 2002.
We need to find the average rate of change in the number of public library visits from 1998 to 2002.
So,
[tex]A=\dfrac{1.5-1.3}{2002-1998}\\\\A=0.05\ \text{billion visits per year}[/tex]
Hence, the required average rate is 0.05 billion visits per year.

Stephan added 26 new contacts to his phone list. He had to delete 16 old contacts before he could add any more. Stefan now has a total of 100 contacts. Let c represent how many contacts he had on his phone list before he updated it. Write an equation and then solve for c.
Answer: 26-16= c
c=10
Step-by-step explanation:
Answer: 90c-16c+26c=100c
Stephan had 90 contacts before he deleted 16 then added 26 more how it works is Stephan had 90 right, then proceeded to delete 16 which left him with 74 contacts after he then added 26 more contacts so he know has 100 contacts.

A survey found that 31% of all teens buy soda (pop) at least once each week. Seven teens are randomly selected. The random variable represents the number of teens who buy soda (pop) at least once each week. What is the value of n
Answer:
The value of n is 7.
Step-by-step explanation:
For each teen, there are only two possible outcomes. Either they buy soda at least once each week, or they do not. Since they were selected randomly, the teens are independent of each other, which means that we use the binomial probability distribution to solve this question.
Binomial probability distribution
The binomial probability is the probability of exactly x successes on n repeated trials, and X can only have two outcomes.
[tex]P(X = x) = C_{n,x}.p^{x}.(1-p)^{n-x}[/tex]
In which [tex]C_{n,x}[/tex] is the number of different combinations of x objects from a set of n elements, given by the following formula.
[tex]C_{n,x} = \frac{n!}{x!(n-x)!}[/tex]
And p is the probability of X happening.
In the binomial distribution, we have that n is the size of the sample. In this question, seven teens are randomly selected, which means that the value of n is 7.

a printing service charges a set up fee of 11.00 for each order and 10 cents more for each copy . the totsl cost, C (in dollars), for an order of x copies is given by the following . C= 11.00+ 0.10x
What is the total cost for an order of 20 copies ?
Answer:
$13.00
Step-by-step explanation:
First, you plug in your x value for copies into the equation C=11.00+0.10x to get a starting equation of x=11.00+0.10(20). Since 0.10 is equivalent to 1/10, it's easy to compute (1/10)(20)=2. You now have an equation of C=11.00+2.00 to get C=13.00. Therefore, the total cost for an order of 20 copies is 13 dollars (and 0 cents).
Which statement about 5(1 + 3x) is true?

D. 5(1 + 3x) is a product of three factors.
well well here it has only one variable that is x
hence option c is correct
Answer:
it is c since it only has one variable

(-4a^2 – 3b) + (-2ab – a^2 + b^2) + (-b^2+6ab)
Answer:
Plato answer!
-5a^2 +4ab - 3b
Step-by-step explanation:
The expression (–4a² – 3b) + (–2ab – a² + b²) + (–b² + 6ab) is equivalent to the expression (–5a² + 4ab – 3b). Then the correct option is D.
What is an equivalent expression?The equivalent is the expressions that are in different forms but are equal to the same value.
The polynomial expression are given below.
(–4a² – 3b) + (–2ab – a² + b²) + (–b² + 6ab)
On simplifying, we have
– 5a² + 4ab – 3b
Then the correct option is D.
