100 students are interviewed to see which of biology, chemistry or physics they prefer.57 of the students are girls. 34 of the girls like biology best.27 of the boys prefer physics.20 out of the 28 who prefer chemistry are girls.What percentage of the students prefer biology?
Answers
Answer:
42%
Step-by-step explanation:
I think it's 42% because out of the 57 girls 34 prefer biology,20 prefer chemistry then it means the remaining 3 prefer physics. There's 43 boys, 8 prefer chemistry,27 prefer physics which leaves us with 8 boys who maybe prefer biology. Therefore:
(34+8)÷100×100 = 42%

Reagan is reading a mystery novel. She has 3 chapters left to read, and each chapter contains 12 pages. The book has 342 pages in all.
Which of the following gives the number of pages Reagan has already read?
342 − (3 × 12) *
342 + (3 × 12)
342 - (12 - 12 - 12)
342 + (-12) + (-12) + (-12) *
378
306 *
(IK the answer it's for future Plato kids, correct answers have a star beside them)
Answers
Answer:
Step-by-step explanation:
342-(12x3) = 306
Total number of pages in the novel = 342 pages
Number of chapters left= 3 chapters
Number of pages in each chapter of the mystery novel = 12 pages
Total number of pages left to read = 12 ×3 = 36
Number of pages Reagan already read = Total pages in the novel - number of pages left for Reagan to read = 342 - 36 = 306
Thus, Reagan has already read 306 pages of a mystery novel.

Multiply the pairs of numbers and match them with their products. Tiles (-5)(4.2) (-7)(-3) (4) (5) (2.5)(-9) Pairs 22.5 21 -22.5 -21 111
Answers
Here are the pairs matched with their products:
- (-5)(4.2) matches with -21
- (-7)(-3) matches with 21
- (2.5)(-9) matches with -22.5
Pairs (4) and (5) do not have corresponding products in the given options.
(-5)(4.2) = -21
(-7)(-3) = 21
(4)(5) = 20
(2.5)(-9) = -22.5
So, the pairs of numbers and their products are as follows:
(-5)(4.2) = -21 matches with -21.
(-7)(-3) = 21 matches with 21.
(4)(5) = 20 matches with 20.
(2.5)(-9) = -22.5 matches with -22.5.

ANSWER NOW! A customer purchased 1/2 pound of ham, 1 pound of turkey, 1 1/2 pound of roast beef, and 1 4 pound of bologna. Approximately what will the customer pay for the purchase before sales tax?
Answers
The total amount the customer will pay is $19.46.
What is Arithmetic?The mathematical branch known as arithmetic deals with the study and application of numbers, their relationships, and mathematical observations.
As per the given data in the question:
In the table, the cost of meat per pound is given:
ham = $5.99
turkey = $4.99
roast beef = $6.99
salami = $2.99
bologna = $3.99
The amount of meat bought by the customer is also given as:
ham = 1/2 pound
turkey = 1 pound
roast beef = 1 1/2 pound = 3/2 pound
bologna = 1/4 pound
For the total amount, the customer will pay for the purchase:
Price for the meat = cost of meat per pound × meat in pounds
= 1/2 × 5.99 + 1 × 4.99 + 3/2 × 6.99 + 1/4 × 3.99
= 2.995 + 4.99 + 10.485 + 0.9975
= $19.46
Hence, The total amount the customer will pay is $19.46.

A.
Paul. He has made 80 pizzas after 9 days.
B.
Cindy. She has made 132 pizzas after 9 days.
C.
Paul. He has made 60 pizzas after 9 days.
D.
Cindy. She has made 48 pizzas after 9 days.
Answers
Answer:
c
Step-by-step explanation:
Paul made 60 pizzas after 9 days because he made 12 pizzas in the first day so 8 days is left and if you multiply 6×8=48 and you add the 12 pizzas of the first day you get 60.
6×8+12=60
the table represent some points on the graph of an exponential function which function represents the same relationship (see image attached)
Answers
Answer: Is the second
Step-by-step explanation:
I took the result of the tables of values with the calculator and it gave me the result I regret not being able to give you an explanation
The exponential function that represents the table is \(y =18 (\frac 65)^x\)
An exponential function is represented as:
\(y = ab^x\)
Where:
a represents the initial valueb represents the rateFrom the table we have the following ordered pair
(x,y) = {(0,18) (1,21.6)}
So, we have:
\(y = ab^x\)
\(18 = a \times b^0\)
\(a= 18\)
Also, we have:
\(y = ab^x\)
\(21.6 = a \times b^1\)
\(21.6 = 18 \times b\)
Divide both sides by 18
\(b = 1.2\)
So, we have:
\(y =18 \times 1.2^x\)
Rewrite as:
\(y =18 (\frac 65)^x\)
Hence, the exponential function that represents the table is \(y =18 (\frac 65)^x\)

So the way I remember the median is the middle number.
So let's lay these numbers in order.
2, 3,3,3,4,5,5,5,5,5,6,7,7,7,9,9
And so if you count from each end, and go to the middle of this list, your answer will be 5!
1.put the numbers in order (least to greatest)
2.then starting crossing off numbers from left to right until u end up with only 1 number that is your median
for this particular problem:
1. we put the numbers in order from least to greatest like I mentioned in step number one
2,3,3,3,4,5,5,5,5,5,6,7,7,7,9,9
2. now we start crossing off numbers from left to right so:
3,3,3,4,5,5,5,5,5,6,7,7,7,9,9
3,3,3,4,5,5,5,5,5,6,7,7,7,9,
3,3,4,5,5,5,5,5,6,7,7,7,9,
3,3,4,5,5,5,5,5,6,7,7,7,
3,4,5,5,5,5,5,6,7,7,7
3,4,5,5,5,5,5,6,7,7
4,5,5,5,5,5,6,7,7
4,5,5,5,5,5,6,7,
5,5,5,5,5,6,7,
