and the cell separates into two identical daughter cells is called ..?
Answer:
cytokineses
Step-by-step explanation:
The phase of the cell cycle where the cytoplasm splits apart and the cell separates into two identical daughter cells is referred to as cytokinesis.
Explanation:The phase of the cell cycle in which the cytoplasm splits apart and the cell separates into two identical daughter cells is called cytokinesis.
Cytokinesis usually follows the other stages of the cell cycle. To put these stages in context: anaphase is the phase in which the chromosomes separate, followed by telophase, in which the separated chromosomes reach opposite ends of the cell. Cytokinesis then occurs, physically splitting the cell in two and thereby creating two identical daughter cells.

The length of a rectangle is three times the width. What is the perimeter of the rectangle if the width is 17 inches?
51 inches
136 inches
204 inches
68 inches
Answer:
136 Inches
Step-by-step explanation:
One side will be x. The other will be 3x.
x=17
3x=51
It is asking for 8x
8x=136
Answer:
136 inches
Step-by-step explanation:
The perimeter of a rectangle can be found using:
p=l+l+w+w
We know the width is 17, and the length is 3 times the width, which is 17
p=(17*3)+(17*3)+17+17
p=51+51+17+17
p=136
So, the perimeter is 136 inches
Your pump empties the water from a swimming pool in 8 hours. When your friend's pump is used together with your pump, the pool is emptied in 2

• A discount movie pass costs $14. With the
pass, movie tickets cost $6 each. Fern
spent a total of $68 on the pass and movie
tickets. How many movies did he see?
Answer:
He saw 9 movies :0
Step-by-step explanation:
First, you take the total cost and subtract the one time cost from it ($68 - $14 = $54) Next, you take the $54 and divide it buy the cost of dollars per movie. ($54/$6 = 9)
So, 9 is your answer.
Hope this helps!!
Final answer:
To find the number of movies Fern saw, subtract the cost of the discount movie pass from the total amount she spent and then divide the result by the cost of each movie ticket. Fern saw 9 movies.
Explanation:
To find the number of movies Fern saw, we need to subtract the cost of the discount movie pass from the total amount she spent and then divide the result by the cost of each movie ticket.
The cost of the discount movie pass is $14, and Fern spent a total of $68. So, $68 - $14 = $54 is the amount she spent on movie tickets.
Since each movie ticket costs $6, we divide the amount she spent on movie tickets by the cost of each movie ticket: $54 ÷ $6 = 9.
Therefore, Fern saw 9 movies.

what does y equal in this equation 5(y+2/5)=-13
The value of y in the given equation equals -3.
What is an Equation?An equation is the statement of two expressions located on two sides connected with an equal to sign. The two sides of an equation is usually called as left hand side and right hand side.
Given equation is,
5(y + 2/5) = -13
We have to find the value of y.
Using the distributive property,
5(y + 2/5) = (5y) + (5 × 2/5)
So,
(5y) + (5 × 2/5) = -13
5y + 2 = -13
Subtracting both side by 2, we get,
5y = -13 - 2
5y = -15
Dividing both sides by 5,
y = -3
Hence the value of y is -3.

Final answer:
To solve the equation 5(y + 2/5) = -13, you distribute the 5 across the parentheses, subtract 2 from both sides, and then divide by 5 to find that y = -3.
Explanation:
To find the value of y in the equation 5(y + 2/5) = -13, we will follow several steps to isolate y. First, we apply the distributive property of multiplication over addition, which gives us 5y + 2 = -13.
Next, we subtract 2 from both sides of the equation, obtaining 5y = -15. Finally, we divide both sides of the equation by 5 to solve for y, resulting in y = -3.

The measure of one side of a square is (x +4). What is the difference of the area of the square and the
perimeter of the square?
a. 2(x+4)
b. x(x +4)
c. 2x + 4
Answer:
b. x(x +4)
Step-by-step explanation:
The perimeter is 4 times the length of one side, so is ...
P = 4(x +4)
The area is the square of the length of one side, so is ...
A = (x +4)(x +4)
The difference in these values is ...
A - P = (x +4)(x +4) - 4(x +4)
The latter factor can be factored out to give ...
A - P = (x +4 -4)(x +4)
A - P = x(x +4) . . . matches B

Which table represents a linear function?
Answer:
What is the tables?
Step-by-step explanation:
Two friends shop for fresh fruit. Elana buys a watermelon for $8.75 and 5 pounds of cherries. Taniy buys a pineapple for $4.25 and 4 pounds of cherries. Use the variable p to represent the price, in dollars, per pound of cherries. Write and simplify an expression to represent how much more Elana spent.
Answer: 4.50 + p
Step-by-step explanation: For this problem we will write and simplify an expression to represent how much more Elana spent.
8.75 + 5p - (4.25 + 4p) ---Distribute the negative sign to the numbers inside the parentheses.
8.75 + 5p - 4.25 - 4p ---Combine like terms
8.75 - 4.25 + 5p - 4p
4.50 + p
So, the expression 4.50 + p represents how much more Elana spent.
Final answer:
Elana spent $4.50 plus the price of 1 pound of cherries more than Taniy. The expression representing this difference is simplified to $4.50 + p.
Explanation:
To find out how much more Elana spent than Taniy, we'll write an expression representing the total amount each person spent, using p as the variable for the price per pound of cherries. Elana's total spending is the cost of the watermelon plus the cost of cherries, expressed as 8.75 + 5p. Taniy's total spending is the cost of the pineapple plus the cost of cherries, expressed as 4.25 + 4p. To find the difference in their spending, we subtract Taniy's total from Elana's total.
The expression representing how much more Elana spent is:
(8.75 + 5p) - (4.25 + 4p)
Now we simplify the expression:
8.75 + 5p - 4.25 - 4p which simplifies to 4.50 + p.
Therefore, Elana spent $4.50 plus 1 pound of cherries more than Taniy.

Answer:
Step-by-step explanation:
3.8×10^{-5}:8.1×10^3
[tex]\frac{3.8 \times 10^{-5}}{8.1 \times 10^3} \\\approx4.69 \times 10^{-9}[/tex]
Performing this mathematical operation in scientific notation gives us the answer 4.691 x 10^-8.
Explanation:To solve this mathematical problem, we will first divide the coefficients and then subtract the exponents of the 10s, because we are dividing. The operation 3.8 ÷ 8.1 equals approximately 0.4691. However, we have to express the coefficient in scientific notation, so we adjust it to 4.691. At the same time, we adjust the exponent by adding 1 to it, to account for the fact that we moved the decimal one place. The operation -5 - 3 equals -8. So, the final answer is [tex]4.691 \times 10^-8.[/tex]
