Step-by-step explanation:
sarah can fit 115 books in 2 bookcases at that rate how many bookcases does she need to hold 360 books?
Answer:115books= 2bookcases
360books=xbookcases
115x=2×360
115x=720
x=720/115
x=6.3 ~ 6bookcases
Step-by-step explanation:
Answer:
7 book cases
Step-by-step explanation:
Add 115 to itself until you reach past 360 (there is a remainder). 115 added 3 times is 345. 115 books=2 bookcases. So you multiply: 2×3=6. Since there is not enough room for all 360 books in 6 bookcases, you need 1 more, which makes it 7 bookcases.
On a coordinate plane, a line goes through (negative 2, negative 4) and (2, 2). A point is at (negative 3, 1).
What is the equation, in point-slope form, of the line that is parallel to the given line and passes through the point (−3, 1)?
y – 1=Negative three-halves(x + 3)
y – 1=Negative two-thirds(x + 3)
y – 1= Two-thirds(x + 3)
y – 1= Three-halves(x + 3)
Answer:
y – 1= Three-halves(x + 3)
Step-by-step explanation:
line goes through (-2, -4) and (2, 2)
goes through (-3, 1)
slope = (-4 - 2) / (-2 -2) = -6/-4 = 3/2
1 = (3/2)*-3 + b
1 = -9/2 + b
b = 1 + 9/2 = 11/2 = 5.5
y = (3/2)*x + 11/2
(y - 1) = (3/2)(x + 3)
The line goes through (-2, -4) and (2, 2)
goes through (-3, 1)
If slope = (-4 - 2) / (-2 -2) = -6/-4 = 3/
1 = (3/2)*-3 + b
1 = -9/2 + b
b = 1 + 9/2 = 11/2 = 5.5
y = (3/2)*x + 11/2
(y - 1) = (3/2)(x + 3)
So the correct answer is option d. y – 1= Three-halves(x + 3).

If XZ = 7x+1 and PZ = 4x-1, what is XP? ( imagine shown below please help)
Answer:
option A. 11 units
Step-by-step explanation:
we know that
The figure show a parallelogram
In a parallelogram the diagonals bisect each other
so
[tex]PZ=\frac{1}{2}XZ[/tex]
[tex]XP=PZ[/tex]
substitute the given values
[tex]4x-1=\frac{1}{2}(7x+1)[/tex]
solve for x
[tex]8x-2=7x+1\\8x-7x=1+2\\x=3[/tex]
Find the value of PZ

On a coordinate plane, a parabola opens up. It goes through (negative 8, negative 2), has a vertex at (negative 5, negative 6.5), goes through (negative 2, negative 2), and has a y-intercept at (0, 6). Over which interval is the graph of f(x) = one-halfx2 + 5x + 6 increasing? (–6.5, ∞) (–5, ∞) (–∞, –5) (–∞, –6.5)
Answer:
The function is increasing in the interval (-5,∞)
Step-by-step explanation:
we have
[tex]f(x)=\frac{1}{2}x^2+5x+6[/tex]
This is a vertical parabola open upward
The vertex represent a minimum
The vertex is the point (-5,-6.5)
The domain is all real numbers
The range is the interval [-6.5,∞)
so
At the left of the x-coordinate of the vertex the function is decreasing and at the right of the x-coordinate of the vertex the function is increasing
therefore
The function is increasing in the interval (-5,∞) and the function is decreasing in the interval (-∞,-5)
Answer:
(–5, ∞)
Step-by-step explanation:
This is a vertical parabola open upward
The vertex represent a minimum
The vertex is the point (-5,-6.5)
The domain is all real numbers
The range is the interval [-6.5,∞)

A soccer ball has a volume of 288π in3. What is the radius of the soccer ball?
Answer:
its 6
Step-by-step explanation:
A soccer ball is in the form of a Sphere.
Volume of a Sphere: V = (4/3)πr3
In this case, V = 288π cm3. So:
1) Substitute the known value into the equation: 288π = (4/3)πr3
2) Notice the π value is on either side of the equation. It cancels: 288 = (4/3)r3
3) Simplifying: r3 = 216
4) Solving for r yeilds : r = 6 cm
The radius (r) of a soccer ball with a volume of 288 cm3 is 6 cm
Answer:
its 6

The phase of the cell cycle in which the cytoplasm splits apart
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.

y = 30.85
10.85
Step-by-step explanation:
One complete cycle is between:
x = 4 and x = 44
Period: 44-4 = 40 cm
Range: 41.7 - 20 = 21.7
Amplitude: 21.7/2 = 10.85
Mean line:
y = 20 + 10.85
y = 30.85
The period of the cosine function is 20, its midline equation is y = 32, and its amplitude is [tex]$\boxed{12}$[/tex].
To analyze the given data, we can notice the sinusoidal nature of the relationship between the number of seconds an object has been moving (x) and its velocity (v(x)$. This indicates that a cosine function can model the data.
Now, let's find the period, midline, and amplitude of the cosine function that models this data.
The period of a cosine function is the distance it takes for the function to complete one full cycle. Looking at the data, we can see that the interval between consecutive peaks or troughs (e.g., between 4 and 24, or 24 and 44) is 20 seconds.
Hence, the period of the cosine function is 20.
The midline of a cosine function is the horizontal line that divides the maximum and minimum values of the function. In this case, since the data oscillates around a central value, it suggests that the midline is not at y = 0.
Instead, it's the average of the maximum and minimum values of the data. The maximum value is 44 and the minimum value is 20, so the midline would be the average of these, which is (44 + 20)/2 = 32.
The amplitude of a cosine function is half the difference between the maximum and minimum values.
In this case, the maximum value is 44 and the minimum value is 20, so the amplitude is (44 - 20)/2 = 12.
So, completing the statements:
- The period of the cosine function is 20.
- The equation of the midline of the cosine function is y = 32.
- The amplitude of the cosine function is [tex]$\boxed{12}$[/tex].

Which equation is true for x = –6 and x = 2?
A.2x^2 – 16x + 12 = 0
B.2x^2 + 8x – 24 = 0
C.3x^2 – 4x – 12 = 0
D.3x^2 + 12x + 36 = 0
Answer: [tex]x^{2} +4x - 12 = 0[/tex]
Step-by-step explanation:
To find the quadratic equation when the roots are given , we will use the formula:
[tex]x^{2} -[/tex] sum of roots[tex](x)[/tex] + product of roots = 0
sum of roots = -6 + 2 = -4
product of roots = -6(2) = -12
substituting into the formula, we have
[tex]x^{2} - (-4) +(-12) = 0[/tex]
[tex]x^{2} +4x - 12 = 0[/tex]
