Emily wants to make a rectangular model with a height of one cube
She wants to make the model in exactly 2 different ways. How many connecting cubes could emily use to make the model in only two ways.
Answer:
Three cubes
Step-by-step explanation:
The cubes have to be indistinguishable and all orientations of one cube are also have to be indistinguishable.
All ways of connecting two cubes result in the same shape. So answer is larger than two.
After connecting two cubes, there are ten faces where the third cube can be attached, and two faces which are connected, accounting for all 12 faces of two cubes.
Of the 10 exposed faces, exactly two are on opposite ends, both leading to the same straight line figure. The other 8 faces all lead to an L shape, and all L shapes can be rotated to be identical.
Hence, three cubes can only make a straight shape or an angled shape.
Four cubes can make a straight shape, a L shape, a Γ shape (but flipping it over through 3 dimensions makes L and Γ identical), a T shape, and a square shape. That is either four or five different objects depending on if they can be lifted from the table. Anyway, it is more than two.
How do I write Domain and Range in inequality notation?
Answer:
Domain: (-infinity, infinity) Range: (-infinity, infinity)
Step-by-step explanation:
They are parabolas, therefore you can assume that they go on infinitely. To find range, you must look at your y values. Look for your lowest point. Because the line goes done forever, your beginning mark would be (-infinity.
To find the other part, you look at your positive y values. Look for the highest value. Because this goes on infinitely, the completed version of your notation would be (-infinity, infinity). Be sure to use the infinity symbol though, which looks like an 8 rotated 90 degrees.
To find domain, look at your x values. To begin, look at your left-most values, which would be the negative numbers. Because the line goes on forever to the left, your notation would be (-infinity. To find the other part of domain, look at your positive x values. Because this line goes on infinitely as well, the completed version of your notation would be (-infinity, infinity). Infinity is never bracketed, it is always in parenthesis.
Diana invests $25,000 in a bank at the beginning of the year. She will receive 7% interest at the end of the year, but she will have to pay a 16% tax on the interest received.
A.) How much interest will Diana earn after she pays the tax?
B.) What percent of Diana's investment is the interest after paying the tax?
Answer:
A) $1470
B) 5,88%
Step-by-step explanation:
B) Diana will end up with 100% -16% = 84% of the interest she earns, so her effective interest rate is ...
... 7% × 84% = 5.88%
A) Diana's investment earns ...
... 0.0588 × $25000 = $1470
After paying a 16% tax on the interest, Diana will earn $1,470 in interest. This represents 5.88% of her original $25,000 investment.
Diana invests $25,000 in a bank at 7% interest, which she will receive at the end of the year. However, she must pay taxes at a rate of 16% on the interest earned.
First, we calculate the total interest Diana would earn without taxes:
Total Interest = Principal imes Interest Rate
Total Interest = $25,000 imes 0.07 = $1,750.
Next, we calculate the tax on the interest:
Tax on Interest = Interest Earned imes Tax Rate
Tax on Interest = $1,750 imes 0.16 = $280.
Now, we subtract the tax from the total interest to find the interest after taxes:
Interest After Taxes = Total Interest - Tax on Interest
Interest After Taxes = $1,750 - $280 = $1,470.
We find the percentage of the original investment that the interest after taxes represents:
Percent of Investment = (Interest After Taxes / Principal) imes 100
Percent of Investment = ($1,470 / $25,000) imes 100 = 5.88%.

x^3-8/x^2+2x+4 divided by (x^2-4)
The simplified expression is [tex]\( \frac{x - 2}{x + 2} \)[/tex].
To divide the expression [tex]\(\frac{x^3 - 8}{x^2 + 2x + 4}\) by \((x^2 - 4)\)[/tex], you first factor both the numerator and denominator.
Factor the numerator:
[tex]\[ x^3 - 8 \][/tex]
[tex]\[= (x - 2)(x^2 + 2x + 4) \][/tex]
This is based on the difference of cubes: [tex]\(a^3 - b^3 = (a - b)(a^2 + ab + b^2)\), where \(a = x\) and \(b = 2\).[/tex]
Now, factor the denominator:
[tex]\[ x^2 + 2x + 4 \][/tex]
[tex]\[= (x + 2)^2 \][/tex]
The expression becomes:
[tex]\[ \frac{(x - 2)(x^2 + 2x + 4)}{(x + 2)^2} \][/tex]
Now, divide by [tex]\((x^2 - 4)\)[/tex]:
[tex]\[ \frac{(x - 2)(x^2 + 2x + 4)}{(x + 2)^2} \div (x^2 - 4) \][/tex]
Factor [tex]\(x^2 - 4\)[/tex] further:
[tex]\[ x^2 - 4 = (x + 2)(x - 2) \][/tex]
Now, cancel out common factors:
[tex]\[ \frac{(x - 2)(x^2 + 2x + 4)}{(x + 2)^2} \div (x^2 - 4) = \frac{x - 2}{x + 2} \][/tex]
Therefore, the simplified expression is [tex]\( \frac{x - 2}{x + 2} \)[/tex].

sherrie opened 5 bags of peanuts and counted a total of 75. At this rate, how many peanuts would be in 8 bags.
Answer:
There should be 120 peanuts
Step-by-step explanation:
We can use ratio's to solve this problem
5 bags
---------------
75 peanuts
5 bags 8 bags
--------------- = ------------------
75 peanuts x peanuts
Using cross products
5x = 75*8
5x = 600
Divide each side by 5
5x/5 = 600/5
x = 120
Answer:
if 5 bags of peanuts = 75peanuts
Then 1 bag will be 15 peanuts beacause 75 divided by 5 is 15
8 bags of peanuts will then be 15 multiply by 8 which is 120 peanuts

Question: Graph the line defined the equation 8x + 8y = 24
Choose: A,B,C or D!!!
Answer:
B
Step-by-step explanation:
8x + 8y = 24
-8x on both sides
8y = -8x + 24
Divide by 8 on both
y = -x + 3
Answer:
B
Step-by-step explanation:
(÷8)8x + 8y = 24(÷8)
x + y = 3
y = - x + 3
If x is negative, then the function is decreasing.
y = - x + 3
When x = 0
y = - 0 + 3
y = 3
(0,3)
When y = 0
- x + 3 = 0
- x = - 3
x = 3

Chloe charged for admission to her play on three different nights. Each night, a different number of people were in attendance, but remarkably, Chloe collected $541 each night. If the admission charges for each child and each adult were $9 and $17, respectively, how many people in total came to the three showings?
To find the total number of people who came to the three showings, divide the total amount collected by the average admission price. Set up equations using the given information for each night and solve simultaneously to find the values of x, y, a, b, p, and q. Add those values to find the total number of people.
Explanation:To find the total number of people who came to the three showings, we need to divide the total amount collected by the average admission price. Let's calculate:
On the first night, let's assume there were x children and y adults. So, we can set up the equation.
9x + 17y = 541.
Similarly, for the second and third nights, we can set up two more equations:
9a + 17b = 541 and 9p + 17q = 541.
Solving these three equations simultaneously will give us the values of x, y, a, b, p, and q, which represent the number of children and adults present on each night. Adding those numbers together will give us the total number of people who came to the three showings.

you work for 40 hours a week at $8.75 an hour and pay 12% in taxes. What is your net pay?
Answer:
Net pay =$ 308
Step-by-step explanation:
Net pay is the gross pay minus taxes
Net pay = gross pay - gross pay * tax rate
Simplifying this equation by factoring out gross pay
Net pay = gross pay (1- tax rate)
Gross pay = hours worked * hourly rate
Substituting this in
Net pay = hours worked * hourly rate (1- tax rate)
We know the
hours worked = 40
Hourly rate = 8.75
tax rate = .12
Net pay = 40 * 8.75 (1- .12)
Net pay = 350(.88)
Net pay =$ 308

B) Rectangle ABCD is rotated 90° clockwise about the origin and then dilated by a scale factor of 1 2 with the origin as the center of dilation.
C) Rectangle ABCD is rotated 90° counterclockwise about the origin and then dilated by a scale factor of 2 with the origin as the center of dilation.
D) Rectangle ABCD is rotated 90° counterclockwise about the origin and then dilated by a scale factor of 1 2 with the origin as the center of dilation.
Answer:
Option D is correct.
Step-by-step explanation:
We are given that,
'Rectangle ABCD is translated to map onto the rectangle EFGH'.
That is, 'Rectangle ABCD is similar to rectangle EFGH'.
So, we see that,
Rectangle ABCD is rotated towards the left and then decreased in size to map onto EFGH.
That is, we have,
Rectangle ABCD is rotated counter-clockwise by 90° about the origin and then dilated by a factor of [tex]\frac{1}{2}[/tex] with the origin as the center of dilation.
Hence, option D is correct.

what are the coefficients in the following expression 8x + 5 + 6y
Answer:
8 5 and 6 are the coefficients
Step-by-step explanation:
For this case we have that by definition, a coefficient is the term that accompanies a variable. If we have the expression given by:
[tex]8x + 5 + 6y[/tex]
The number "5" is a constant.
Thus, two variables, "x" and "y", are observed.
Thus according to the definition, the coefficients are given by "8" and "6" respectively.

A particular leg bone for dinosaur fossils has a mean length of 5 feet with standard deviation of 3 inches. What is the probability that a leg bone is less than 62 inches
Answer:
The probability of a leg bone measuring less than 62 inches is about 75% (74.86%).
Step-by-step explanation:
To answer this question we can calculate the z-score, then use a table to look up a corresponding percentile using z tables.
The length is a random variable with mean = 60 in and standard deviation of 3 in and we are looking at a particular sample that 62 in long. That sample has the following z value:
[tex]z = \frac{62 - \mu}{\sigma}=\frac{62-60}{3}=\frac{2}{3}\approx0.67[/tex]
The area under the normal distribution curve that corresponds to the z value of 0.67 (using a z table - available on line) is 0.7486. This is the probability that a random sample of a fossil leg length is less that our particular value 62 inches. Roughly speaking, the probability of a leg bone less than 62 in is about 75% (aka 75-th percentile).

The heights of two cylinders are in the ratio 3:1 if the volumes of two are same find the ratio of their respective radii
Answer:
[tex]\sqrt{3}[/tex] :1
Step-by-step explanation:
Ratio of height of two cylinders are 3:1
Let C2 has the height x
then height of C1 is 3x
Let r1 is the radius of C1
and r2 is the radius of C2
As given that volume of both are equal
Also we know that formula for the volume of the cylinder is
V= π r²h
for C1
V= π (r1)²h
for C2
V=π (r2)²h
As volume of both are same so equating them
π (r1)²h1 = π (r2)²h2
as h1 =3x and h2=x
putting values
π (r1)²(3x) = π (r2)²(x)
cancelling out π and x from both side of the equation
3(r1)²= (r2)²
Taking square root of both sides give
[tex]\sqrt{3(r1)^{2} }=\sqrt{(r2)^{2} }[/tex]
r1 ( [tex]\sqrt{3}[/tex]) = r2
or
r1 : r2 = [tex]\sqrt{3}[/tex] :1
