3. The density of an object can be found with this formula...
D = M/V
D = Density, M = Mass, and V = Volume
Choose the correct equation for an object that has...
Density = ?, Volume = 10cm, Mass = 500g

HELP3. The Density Of An Object Can Be Found With This Formula...D = M/VD = Density, M = Mass, And V

Answers

Answer 1
Answer: Choice A) D = 500/10

Explanation:

Density = Mass/Volume

D = M/V

D = 500/10

D = 50 grams per cubic cm

Your teacher should have written cm^3, cc, or cubic cm instead of just "cm" to represent the volume. The abbreviation "cc" stands for "cubic cm" which you may hear a lot in hospital settings when it comes to medicine dosages.

Answers

Answer:

$1500

Step-by-step explanation:

If the television is marked down by 25%, it means that the price was reduced by 25%. This means that the television would be 100% - 25% = 75% of the original price.

The price of the television following the mark down=

Answers

Answer:

Dividing negative exponents is almost the same as multiplying them, except you're doing the opposite: subtracting where you would have added and dividing where you would have multiplied. If the bases are the same, subtract the exponents. Remember to flip the exponent and make it positive, if needed.

Answers

Answer:

y = -5

Step-by-step explanation:

-10(-1/2y + (-7/2)) + 7y = -25

Let's first of all expand the bracket to get;

5y + 35 + 7y = -25

12y + 35 = -25

12y = -25 - 35

12y = -60

y = -60/12

What are the coordinates of A after a dilation of 2/3 centered at the origin? Question 11 options:

A' =(−3/4, −3/2)

A' = (4/3, 2/3)

A' = (2, 1)

A' =(2/3, 2/3)

Answers

Answer:

The image of A(2, 1) after dilation by a scale factor of 2/3 will be: A'(4/3, 2/3) .

Step-by-step explanation:

Given

Point A (2, 1)

We know that when an object is dilated by a scale factor, it gets reduced, stretched, or remains the same, depending upon the value of the scale factor.

If the scale factor > 1, the image is enlarged If the scale factor is between 0 and 1, it gets shrunk If the scale factor = 1, the object and the image are congruent

Rule to calculate the dilation by a scale factor 2/3 centered at the origin

P(x, y) → P'(2/3x, 2/3y)

Here, P'(2/3, 2/3y) is the image of P(x, y).

It means the coordinates of the image can be determined by multiplying the coordinates of the original point by 2/3.

Thus,

A(2, 1) → A'(2/3(2), 2/3(1)) = A'(4/3, 2/3)

Therefore, the image of A(2, 1) after dilation by a scale factor of 2/3 will be: A'(4/3, 2/3) .

A store advertises 15% off an item that regularly sells for $300

what is the price of the item?

Answers

The item would sell for $255 if it had a 15 percent discount

For this problem, we're finding the percent of 300. To do that we:

1. Multiply 300 by 15.

300 x 15 = 4500

2. Divide 4500 by 100. (% = 100)

4500 / 100 = 45

Therefore, the unit price is 45. But we're not done. We need to subtract 45 by 300.

300 - 45 = 255

Now, our answer is 255 and the unit price is 45.

Find the dimensions of the square.

Area = 441 cm²

Answers

Answer:

21 cm by 21 cm

Step-by-step explanation:

The formula for the area of a square is A = x^2, where x is the length of any one side of the square.  Here,

441 cm² = x²

This actually has two roots:  {√441, -√441), but since x must be positive here, to be a dimension of the square, we choose +√441, or +21.

The dimensions of the square are 21 cm by 21 cm.

Patrick is riding his bike on a rectangular path around his city. There is a rest area at each of the path's four corners. The city map shows the corners marked with coordinates of (–2, 2), (1, 2), (1, –2), and (–2, –2). Each unit represents 2.5 miles.

Answers

Question:

What is the perimeter of the path, in miles?

Answer:

35 miles

Step-by-step explanation:

Given

Let the corners be ABCD

[tex]A = (-2,2)[/tex]

[tex]B = (1,2)[/tex]

[tex]C = (1,-2)[/tex]

[tex]D = (-2,-2)[/tex]

First, we calculate the perimeter of the corners in units.

This is done by calculating the distance between the corners.

Distance is calculated as:

[tex]D = \sqrt{(x_2 - x_1)^2 +(y_2 - y_1)^2 }[/tex]

For AB:

[tex](x_1,y_1) = (-2,2)[/tex]

[tex](x_2,y_2) = (1,2)[/tex]

[tex]D_1 = \sqrt{(1 - (-2))^2 +(2 - 2)^2 }[/tex]

[tex]D_1 = \sqrt{(1 +2)^2 +(0)^2 }[/tex]

[tex]D_1 = \sqrt{3^2}[/tex]

[tex]D_1 = 3[/tex]

For BC

[tex](x_1,y_1) = (1,2)[/tex]

[tex](x_2,y_2) = (1,-2)[/tex]

[tex]D_2 = \sqrt{(1 - 1)^2 +(-2 - 2)^2 }[/tex]

[tex]D_2 = \sqrt{(0)^2 +(-4)^2 }[/tex]

[tex]D_2 = \sqrt{16 }[/tex]

[tex]D_2 = 4[/tex]

For CD:

[tex](x_1,y_1) = (1,-2)[/tex]

[tex](x_2,y_2) = (-2,-2)[/tex]

[tex]D_3 = \sqrt{(-2 - 1)^2 +(-2 - (-2))^2 }[/tex]

[tex]D_3 = \sqrt{(-3)^2 +(-2 +2)^2 }[/tex]

[tex]D_3 = \sqrt{9 +0^2 }[/tex]

[tex]D_3 = \sqrt{9 }[/tex]

[tex]D_3 = 3[/tex]

For DA

[tex](x_1,y_1) = (-2,-2)[/tex]

[tex](x_2,y_2) = (-2,2)[/tex]

[tex]D_4 = \sqrt{(-2 - (-2))^2 +(2 - (-2))^2 }[/tex]

[tex]D_4 = \sqrt{(-2 +2)^2 +(2 +2))^2 }[/tex]

[tex]D_4 = \sqrt{0^2 +4^2 }[/tex]

[tex]D_4 = \sqrt{4^2 }[/tex]

[tex]D_4 = 4[/tex]

The perimeter P in units is:

[tex]P = D_1 + D_2 + D_3 + D_4[/tex]

[tex]P = 3+4+3+4[/tex]

[tex]P = 14[/tex]

Given that:

[tex]1\ units = 2.5\ miles[/tex]

Multiply both sides by 14

[tex]14 * 1\ units = 14 * 2.5\ miles[/tex]

[tex]14 \ units = 35\ miles[/tex]

Hence, the perimeter is 35 miles
