A study found that 9% of dog owners brush their dog’s teeth. Of 578 dog owners, about how many would be expected to brush their dog’s teeth? Explain.
A.
50; 9% ≈ 10% and 578 should be rounded down to 500; 10% of 500 = 50
B.
60; 9% ≈ 10% and 578 ≈ 600; 10% of 600 = 60
C.
70; 9% ≈ 10% and 578 ≈ 700; 10% of 700 = 70
is it A. B. or C.
Answer: A

If Sue does not deposit additional money into the accounts and she doesn't withdraw any money from the accounts, which is closest to the total balance she will have in the two accounts at the end of 5 years
The required total balance at the end of the 5 years is given as $1995.

Investment 1,
Amount = P(1 + rt)
Amount = 600(1 + 0.075×5)
Amount = $825
Investment 2,
Amount = P(1 + rt)
Amount = 900(1 + 0.06×5)

How can I find the cube root of 64?
Answer:
4
Step-by-step explanation:
The cube root of 64 is the number which when multiplied by itself three times gives the product as 64. Since 64 can be expressed as 2 × 2 × 2 × 2 × 2 × 2. Therefore, the cube root of 64 = ∛(2 × 2 × 2 × 2 × 2 × 2) = 4.
The cube root of 64 is 4.
Before solving the question, let's understand the concept of cube root.
The cube root of a number is the value obtained by multiplying it by itself three times or thrice. When we multiply 3 by itself three times, we get 3 x 3 x 3 = 27 = 3³, so the cube root of 27 is 3. Thus, we can say that the cube root gives a value that is basically cubed.
The cube root is denoted by ∛
Now, we will find the cube root of 64.
Firstly, we have to find factor 64.
64 = 2 × 2 × 2 × 2 × 2 × 2.
64 = ∛4³
64 = 4
Therefore, the cube root of 64 is 4.

12 ft.^3 What is the width of the box? Explain how you found the width.
Correct answer gets BRAINLIEST
Answer:
The perimeter is 380 ft^2.
Step-by-step explanation:
To find the perimeter of a rectangle, you have to use the 2(a+b) formula as a method of solving. This formula can also be written as a+b+a+b or 2a+2b.
To solve it, you input a as 51 and 139 as b, though this doesn't really matter all too much. Using the previously stated formula, you should get 2(51+139). Solving what's in the parenthesis first (51+139), you should get 190.
Now, you should have the answer 2(190). Finishing off the equation and multiplying 2 by 190, your answer will be 380 ft^2.

The function for the points are y = -15x - 5
How to determine the functionFrom the information given, we have that;
The points are;
(1/3,0) (-2 3/4,0) and (0,-5)
Using the point-slope form of a linear equation, we have;
y - y₁ = m(x - x₁)
Such that;
m is the slope of the liney - y₁ and (x - x₁) are the pointsUsing (1/3, 0) and (0, -5), we have that the slope is;
m = (0 - (-5))/0 -1/3)
expand the bracket
= 5 / (-1/3)
= -15
Now, take any of the given points and substitute the values
Using (1/3, 0), we get;
y - 0 = -15(x - 1/3).
y = -15x - 5.

The function for the points solved by (1/3,0) (-2 3/4,0) and (0,-5) solved by point slope form is \(a=-15b-5\)
We have given the points:
(1/3,0) (-2 3/4,0) and (0,-5)
Using the formula of linear equation
\(a-\)\(a_{1}\)\(=x[b-b_{1}]\)
Where we will consider (1/3,0) = \(a-a_{1}\) and (0,-5) = \(b-b_{1}\)
that is 1/3 = \(a\), 0 = \(a_{1}\) and
0 = \(b\), -5 = \(b_{1}\)
\(x\) refers to the slope of line (take any variable)
Now for finding the value of \(x\),
\(x=a-a_{1}/b-b_{1}\)
inserting the values,
\(x=[0-[-5]]/[0-1/3]\\x= -15\)
Substitute the value of \(x\) in the equation
\(a-0=-15[b-1/3]\)

Step-by-step explanation:
First of all, it says you can use a calculator! If you do not know how to, let me know in the comments and I can try to help you out! Read the explanation to understand how to do this.
Question 17
Using a calculator, you get 6.48074069… for your decimal.
Rounding it to the nearest tenth, your answer would be 6.5
Now, to find the two consecutive whole numbers the square root is between…
However, there is another way to do this. Remember that 7x7=49. We know that 49 is greater than 42, so let’s see try out a number smaller than 7! 6x6=36. 42 is between 36 and 49, so the square root is between 6 and 7.
Another way to do this is… we know that the decimal is about 6.5, which is between 6 and 7, since those are the two whole numbers before and after that decimal!
Question 18
Using a calculator, you get 9.380833151… for your decimal.
This rounds to 9.4
The whole numbers surrounding this decimal are 9 and 10.
You can also do this by knowing that 9x9, or 9^2, is 81 and 10x10, or 10^2, is 100, and those are the numbers surround 88.
In non-decimal form (simplified radical), your answer can be 2√22.
Question 19
Using a calculator, you get 7.93725393… for your decimal.
This rounds to 7.9
The whole numbers surrounding this decimal are 7 and 8.
You can also do this by knowing that 7x7, or 7^2, is 49 and 8x8, or 8^2, is 64, and those are the numbers surround 63.
In non-decimal form (simplified radical), your answer can be 3√7.
Question 20
Using a calculator, you get 8.66025403… for your decimal.
This rounds to 8.7
The whole numbers surrounding this decimal are 8 and 9.
You can also do this by knowing that 8x8, or 8^2, is 64 and 9x9, or 9^2, is 81, and those are the numbers surround 75.
In non-decimal form (simplified radical), your answer can be 5√3.
Question 21
Using a calculator, you get 5.47722557… for your decimal.
This rounds to 5.5
The whole numbers surrounding this decimal are 5 and 6.
You can also do this by knowing that 5x5, or 5^2, is 25 and 6x6, or 6^2, is 36, and those are the numbers surround 30.
Question 22
Using a calculator, you get 9.84885780… for your decimal.
This rounds to 9.8
The whole numbers surrounding this decimal are 9 and 10.
You can also do this by knowing that 9x9, or 9^2, is 81 and 10x10, or 10^2, is 100, and those are the numbers surround 97.
Note: the symbol "^" means that the number following that symbol is an exponent. So 2^2 is 2 squared, \(2^2\), or 2 to the power of 2.

Is the relationship in the table an example of a proportional relationship? Show your work and explain why or why not.
Answer:
The relationship in the table is not an example of proportional relationship.
Step-by-step explanation:
This is because the difference between 3.38 and 1.69 is 1.69 but the difference between 8.45 and 3.38 is not 1.69 thus making it not a constant slope so this table doesn't represent a proportional relationship.

x-2y=3, x^2-2y=3, x^2-2xy+4y^2=11, find the value of x^2y-2xy^2
This is a system of three equations with two unknowns, x and y. To solve it, we can use the method of elimination. First, we can eliminate y by subtracting the first equation from the second equation:
x^2-2y=3 - (x-2y=3) => x^2-x=0
Then we can factor the resulting equation and find the values of x:
x^2-x=0 => x(x-1)=0 => x=0 or x=1
Next, we can substitute these values of x into any of the original equations and find the corresponding values of y. For example, using the first equation:
x-2y=3 => 0-2y=3 => y=-3/2 when x=0 x-2y=3 => 1-2y=3 => y=-1 when x=1
Finally, we can substitute these values of x and y into the expression x2y-2xy2 and evaluate it:
x2y-2xy2 => 02(-3/2)-2(0)(-3/2)2 => 0 when x=0 and y=-3/2 x2y-2xy2 => 12(-1)-2(1)(-1)2 => -3 when x=1 and y=-1
Therefore, the value of x2y-2xy2 can be either 0 or -3 depending on the values of x and y.
