is 1000 a perfect cube?

Answers

Think of a cube with side lengths of 10.

The volume of the cube will be L*W*H = 10*10*10 = 1000

This volume of 1000 is what we consider a perfect cube.

Answer: yes

10*10*10=[tex]10^{3}[/tex]

10*10*10=1,000

1,000 is a perfect cube, because 10^3 is 1,000.

I am very confused lol... So I'm doing a worksheet for Algebra 1 (highschool) and we're doing division and multiplication with fractions at the moment to review what we learned last year and I'm stuck. Right now I'm doing #1 and ended up getting 7 1\2... so I ended up doing this as my equation..
[tex]3 \frac{3}{4} \div \frac{1}{2} [/tex]I have no idea if I'm supposed to do division with this but I tried division and multiplication and got 7 1\2 Everytime I did it. And I know the answer is 1 7/8 cause I may have found a cheat sheet online but I still need to know how to do it. Anyways this is what I did:
[tex]3 \frac{3}{4} \div \frac{1}{2} [/tex]
[tex] \frac{15}{4} \times \frac{2}{1} = \frac{30}{4} [/tex]
[tex] \frac{30}{4} = \frac{15}{2} = 7 \frac{1}{2} [/tex]
I don't understand what I'm doing wrong lol.

Answers

OK first change 3 3/4 to an improper fraction and that will give you  15/4. so you got that part right.  Next, change the division sign to multiplication. then flip the 1/2 to 2/1.  Then multiply 15 times 2 and that will give you 30. Then multiply 4 times 1 and that will give you 4. then you will have an answer of  30/4. Finally, since you a have a big number over a small number you divide 30 by 4 and that will give you 7 1/2. So it turns out that your little cheat sheet is wrong because when you check your answer you should go on Math-way to check it. Also, a little background about me is that I am in 8th grade and I am taking algebra 1 too.

Edward Taylor purchased two shirts for $17.95 and $27.50, a jacket for $94.20, and two ties for $12.30 each. The state tax is 5 percent, the county tax is 1.5 percent, and the city tax is 2 percent. What is the total amount of tax on his purchases?

A. $14.65

B. $12.97

C. $13.96

D. $11.23

Answers

Total cost

17.95 + 27.50 + 94.20 + 12.30 + 12.30 = 164.25

tax

164.25 * 5% = 8.21

164.25 * 1.5% = 2.47

164.25 * 2% = 3.28

sum of the tax

8.21 + 2.47 +3.28 =

13.96

your answer is C

Final answer:

To find the total tax on Edward Taylor's purchases, sum the cost of all items ($164.25), multiply by the combined tax rate of 8.5% to get the total tax in dollars ($13.96125), and round to the nearest cent, resulting in $13.96. So, option C is correct.

Explanation:

To determine the total amount of tax on Edward Taylor's purchases, we need to sum up the cost of all items purchased and then calculate the combined sales tax. Edward bought two shirts for $17.95 and $27.50, a jacket for $94.20, and two ties at $12.30 each. Here are the steps taken:

Calculate the sum of the purchases: $(17.95 + 27.50 + 94.20 + 12.30 + 12.30) = $164.25.

Combine the tax rates: (state tax at 5% + county tax at 1.5% + city tax at 2%) = 8.5% total.

Convert the tax rate to a decimal: 8.5% = 0.085.

Multiply the total cost of purchases by the tax rate: $164.25 * 0.085 = $13.96125.

Round the tax to the nearest cent: $13.96.

Therefore, the total amount of tax on his purchases is $13.96. So, option C is correct.

Triangle ABC has vertices at A(−1 , 2), B(4, 2), and C(3, −1). Classify the triangle according to the side lengths.

A) equilateral
B) isosceles
C) right
D) scalene

Answers

Answer:

B) Isosceles

Step-by-step explanation:

The given triangle has vertices at A(-1,2), B(4,2) and C(3,-1).

We must first determine the length of the sides of the triangle, before we can classify it.

We apply the distance formula to find length of the sides.

[tex]|AB|=\sqrt{(4--1)^2+(2-2)^2}[/tex]

[tex]\Rightarrow |AB|=\sqrt{(4+1)^2+(2-2)^2}[/tex]

[tex]\Rightarrow |AB|=\sqrt{5^2+(0)^2}[/tex]

[tex]\Rightarrow |AB|=\sqrt{25}[/tex]

[tex]\Rightarrow |AB|=5 units[/tex].

The length of side BC

[tex]|BC|=\sqrt{(3-4)^2+(-1-2)^2}[/tex]

[tex]\Rightarrow |BC|=\sqrt{(-1)^2+(-3)^2}[/tex]

[tex]\Rightarrow |BC|=\sqrt{1+9}[/tex]

[tex]\Rightarrow |BC|=\sqrt{10}[/tex]

The length of side AC

[tex]|AC|=\sqrt{(3--1)^2+(-1-2)^2}[/tex]

We simplify to obtain;

[tex]|AC|=\sqrt{(3+1)^2+(-3)^2}[/tex]

[tex]\Rightarrow |AC|=\sqrt{(4)^2+(-3)^2}[/tex]

[tex]|AC|=\sqrt{16+9}[/tex]

[tex]|AC|=\sqrt{25}[/tex]

[tex]|AC|=5\:units[/tex]

Since [tex]|AC|=5\:units=|AB|[/tex], the given triangle is an isosceles triangle.

The correct answer is

B) isosceles

A case of 24 pairs of the same kind of sports shoes costs a little more than $800.Explain whether $28 per pair with tax included is a good estimate.

Answers

No because 24 times 28 is 672

Answer:

$28 per pair is not a good estimate.

Step-by-step explanation:

Let x represent cost of each pair with tax.

We have been given that a case of 24 pairs of the same kind of sport shoes cost a little more than $800.

The cost of 24 pairs would be [tex]24x[/tex].

[tex]24x>800[/tex]

[tex]\frac{24x}{24}>\frac{800}{24}[/tex]

[tex]x>33.33[/tex]

Since the cost of each pair is greater than $33.33, therefore, $28 is not a good estimate.

Answers

Answer:

Option D is the correct answer.

Explanation:

 The points (0, 1), (1, 5), (2, 25), (3, 125) are on the graph of a function.

We need to find f(x)

Checking each options.

a) f(x) = [tex]2^x[/tex]

    For (0,1)

              f(0) = [tex]2^0=1[/tex]

    For (1,5)

              f(1) =  [tex]2^1=2[/tex], given that f(1) = 5, so option A is wrong.

b) f(x) = [tex]3^x[/tex]

   For (0,1)

              f(0) = [tex]3^0=1[/tex]

    For (1,5)

              f(1) =  [tex]2^1=3[/tex], given that f(1) = 5, so option B is wrong.

c) f(x) = [tex]4^x[/tex]

   For (0,1)

              f(0) = [tex]4^0=1[/tex]

    For (1,5)

              f(1) =  [tex]4^1=4[/tex], given that f(1) = 5, so option C is wrong.

d) f(x) = [tex]5^x[/tex]

   For (0,1)

              f(0) = [tex]5^0=1[/tex]

    For (1,5)

              f(1) =  [tex]5^1=5[/tex]

   For (2,25)

               f(2) =  [tex]5^2=25[/tex]

  For (3,125)

               f(3) =  [tex]5^3=125[/tex]

 So all values are satisfied Option D is the correct answer.

The lateral surface area of cone A is equal to the lateral surface area of cylinder B.
True or false

Answers

Answer:

TRUE

Step-by-step explanation:

Lateral area of cone is given by: πrl

where r is the radius and l is the slant height

Here r=r and l=2h

Hence, lateral area of cone A= π×r×2h

                                            =  2πrh

Lateral area of cylinder is given by: 2πrh

where r is the radius and h is the height

Lateral area of cylinder B=2πrh

Clearly, both the lateral areas are equal

Hence, the statement that:The lateral surface area of cone A is equal to the lateral surface area of cylinder B. is:

True

Answer:

The midpoint of AB is (0.5,1).

Step-by-step explanation:

From the given graph it is clear that the vertices of the triangle ABC are A(-2,5), B(3,-3) and C(-4,-1).

If end points of a line segment are [tex](x_1,y_1)[/tex] and [tex](x_2,y_2)[/tex], then the midpoint of that segment is

[tex]Midpoint=(\frac{x_1+x_2}{2},\frac{y_1+y_2}{2})[/tex]

[tex]Midpoint=(\frac{-2+3}{2},\frac{5+(-3)}{2})[/tex]

[tex]Midpoint=(\frac{1}{2},\frac{5-3}{2})[/tex]

On further simplification we get

[tex]Midpoint=(\frac{1}{2},\frac{2}{2})[/tex]

[tex]Midpoint=(0.5,1)[/tex]

Therefore the midpoint of AB is (0.5,1).

18x^2-2 factor completely

Answers

Here is your answer to your question

The factored form of [tex]\(18x^2 - 2\)[/tex] is [tex]\({2(3x - 1)(3x + 1)}\)[/tex].

To factor the expression [tex]\(18x^2 - 2\)[/tex] completely, we first notice that [tex](18x^2\))[/tex] and [tex]\(2\)[/tex] share a common factor of [tex]\(2\)[/tex]. We can factor out this common factor to simplify the expression:

[tex]\[18x^2 - 2 = 2(9x^2 - 1)\][/tex]

Now, we recognize that [tex]\(9x^2 - 1\)[/tex] is a difference of squares. It can be factored as [tex]\((3x)^2 - 1^2\)[/tex], which follows the pattern [tex]\((a^2 - b^2) = (a - b)(a + b)\)[/tex].

So, applying this pattern, we have:

[tex]\[9x^2 - 1 = (3x)^2 - 1^2 = (3x - 1)(3x + 1)\][/tex]

Therefore, the expression \(18x^2 - 2\) factors completely as:

[tex]\[18x^2 - 2 = 2(9x^2 - 1) = 2(3x - 1)(3x + 1)\][/tex]
