Answer:
Ken, Leon, and Mark collect seashells as a hobby. Ken has (3x - 5) seashells, Leon has (2x +1) seashells, and Mark has (0.25x + 7) seashells. a. Write an expression for the total number of seashells they collected.
The answer:
Ken has 5 shells, Leon has 2 shells, Mark has 1.50 shells
how do we know:
because the 5 is negative we have -5 + -5=0 because negatives only go up by subtracting so 0+-5 is 5.
because the 1 is positive we can do 1+1 as were doing 2x1 so 1+1=2.
because we are doing 0.25x7 we need to know that we can flip the problem so we get 7x0.25. this makes things easy for you and me, we already know that 4 0.25's make 1 and we also know that 0.25+0.25 is 0.50 and 1 + 0.50 is 1.50 or just 1.5

Jenny is studying the growth of a particular type of plant. She is testing the effects of three growth factors: lighting, age, and temperature. Here are the levels she's testing for each.
Growth factor Levels
Lighting Low, Medium, High, Very high
Age month, months, months, months, months
Temperature , , ,
She wants to find the number of ways of combining one level from each of the growth factors. How many ways are there?
Answers
Answer:
there are so many ways
Step-by-step explanation:
such as observing day by day and checking its height with a scale everyday etc
The number of ways of combining different growth factors to form a level is 80.
What is Permutation?The act of organizing all the components of a set into some sequence or order is known as permutation. Permuting, in other words, is the act of reordering the components of a set that has previously been sorted.
A permutation is the selection of r items from a collection of n items without replacement, with the order of the items being significant.
nPr = (n!) / (n-r)!
What is a Combination?The combination is a method of picking elements from a collection in which the order of selection is irrelevant (unlike permutations).
A combination is a selection of r items from a collection of n items with no replacements and no regard for order.
nCr = (n!)/{(r!)((n-r)!)}
How do we solve the given question?We are given that Jenny is studying the growth of a particular type of plant. She is testing the effects of three growth factors: lighting, age, and temperature. Here are the levels she's testing for each.
Growth factor Levels
Lighting: Low, Medium, High, Very high.
Age: 1 month, 2 months, 3 months, 4 months, 5 months.
Temperature: 20°, 22°, 24°, 26°.
We are asked to find the number of ways in which she can combine different levels to form one level.
We first check the number of combinations for each factor and then multiply them all to get the total number of ways possible.
Lighting: 4 (∵ All the 4 levels are possible, so the combinations are 4P1 = 4).
Age: 5 (∵ All the 5 levels are possible, so the combinations are 5P1 = 5).
Temperature: 4 (∵ All the 4 levels are possible, so the combinations are 4P1 =4).
∴ Total number of ways of combining different growth factors to form a level = 4*5*4 = 80
∴ The number of ways of combining different growth factors to form a level is 80.

What type of transformation happened from (x,y) --> (-x,y)?
-----
A.Rotation 90*
B.Reflection over the y-axis
C.Translation left 1
D.Reflection over the x-axis
Answers
Answer:
B
Step-by-step explanation:
This is a reflection over the y-axis. The x value is changing sign while the y value is staying the same. The general rule for a reflection over the y axis is (x,y) --> (-x,y), and similarly for a reflection over the x axis is (x,y) --> (x,-y). When you reflect a point over an axis, you flip the sign of the opposite value.

Tyrone read a book for his school project. On the first day, he read 40 pages. On the second day, he read 1 4 of the remaining pages. After the second day, he still had to read 1 2 of the total number of pages to complete the book. How many pages are there in the book?
Answers
Answer:
160
Step-by-step explanation:
he read 40 pages on the first day. he read 1/4 of the remaining pages, and still had 1/2 of the book to read. this means that 40 is about 1/4 and to find the total amount of pages, you have to multiply 40 by 4.
40 x 4 = 160
hope this helps :)
Answer:
70 pages. (If by 1 4 and 1 2, you mean fractions.)
Step-by-step explanation:
1/4 of 40 is 10. This is calculated by dividing 40 by 4, since the denominator in 1/4 is 4.
1/2 of 40 is 20. This is calculated by dividing 40 by 2, since the denominator in 1/2 is 2.
Add that together and that's 70.

Q: Which statement is correct for the graph of the specified function?
A: The maximum value of the quadratic function occurs at y = 4.
Step-by-step explanation: The minimum value of the quadratic function occurs at x = 0 is false because this quadratic does not have a minimum value. It has a maximum value when y=4. The true statement is that the x-values of the linear function increase (go up) as the y-values decrease (go down). Also i took the test

• Find the area, in square blocks, of the park section of the property. Show all your work.
• Find the total area, in square blocks, of the sections with homes. Show all your work.
• If the developers paid $500.00 per square block, how much did they pay for all the property being developed? Explain your answer.
Answers
Answer:
$97500.00
Step-by-step explanation:
the homes of the homes facing south is 10 times (7 plus 3) = 100 blocks
the area of the east facing homes is 8 times 10= 80 blocks
and the area of the trapezoid is 5 plus 3 times 3 = 15 blocks
so 100+80+15= 195 square blocks
195 times 500 = $97500.00

Step-by-step explanation:
The smiley face has a radius of 8 centimeters.
We need to find the area of the smiley face.
The formula to find the area of a circle is:
A = [tex]\pi[/tex]r²
A = (3.14)(8)(2)
A = (25.12)(2)
A = 50.24
The area of the smiley face would be 50.24 square feet.
