Chantelle has signed up for hockey. Her parents set a limit of $400 for costs for the season. It costs $250 to sign up and $5 for each ice-time. What is the maximum number of ice-times that Chantelle can go?
Answer:
30 times
Step-by-step explanation:
$400 minus $250=$150
$150 divided by $5=30 so she can go 30 times
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]

|6m−2|=0 please help
Answer:
m = 1/3
Step-by-step explanation:
Answer: m = 1/3
Step-by-step explanation: Lets solve the equation |6m - 2| = 0.
|6m - 2| = 0
Find absolute values of 6m - 2
-6m + 2 = 0 (Now solve both sides of the equation.)
-6m + 2 - 2 = 0 - 2
-6m = -2
-6m/-6 = -2/-6
m = 1/3
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.

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.

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:

The data in the table shows a sinusoidal relationship between the number of seconds an object has been moving and its velocity v(x), measured in centimeters per second. What is true of the cosine function that models the data in the table?

Answer:

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].

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.

3.8 x 10^-5 : 8.1 x 10^3
[?]×10'?
Coefficient (green)
exponent (yellow)
Enter
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]

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
