Answer:

[tex]1600\ \text{people per square mile}[/tex]

Step-by-step explanation:

Number of people per square mile in City A is 6000.

In terms of size City B is a dilation of City A with scale factor 1.5.

This means a length of 1 mile in city A would be 1.5 miles in city B.

So, [tex]1\ \text{mile}^2\text{ in City A}=1.5^2\ \text{mile}^2\text{ in City B}[/tex]

City B has [tex]\dfrac{3}{5}[/tex] of the population of City​ A.

So the population density of City B would be

[tex]\dfrac{\dfrac{3}{5}\times 6000}{1.5^2}=1600\ \text{people per square mile}[/tex]

The population density of City​ B is [tex]1600\ \text{people per square mile}[/tex].

Answer:

60

Step-by-step explanation:

m and n are parallel the 3x=180

180/3=60

Answer:

No because the a and b lengths are too big and the c length is too small

Step-by-step explanation:

a^2 + b^2 = c^2

5^2 + 7.5^2 = 2.5^2

25 + 56.25 = 6.25

Answer:

Volume of the triangular prism = 448 cm³

Step-by-step explanation:

Volume of the triangular prism = Area of the triangular base × Height of the triangular prism

Area of the triangular base = [tex]\frac{1}{2}(\text{Base})(\text{Height})[/tex]

= [tex]\frac{1}{2}(8)(16)[/tex]

= 64 units²

Volume of the triangular prism = 64 × 7

= 448 cm³

Answer:

The answer is, q = 16.

Step-by-step explanation:

1) Divide both sides by 3.

[tex]q - 7 = \frac{27}{3} [/tex]

2) Simplify 27/3 to 9.

[tex]q - 7 = 9[/tex]

3) Add 7 to both sides.

[tex]q = 9 + 7[/tex]

4) Simplify 9 + 7 to 16.

[tex]q = 16[/tex]

Therefor, the answer is q = 16.

Answer:

q=16

Step-by-step explanation:

To solve this problem, you'll want to start by distributing the 3 to both q and -7, which will give you 3q-21=27. Then, you should add 21 to both sides, which will get the variable alone on one side of the equation. After that step, your equation should be 3q=48. Lastly, divide both sides by 3, which will give you the answer q=16!

Answer:

x = 2.8

Step-by-step explanation:

x/7 = 0.4

multiply both sides by 7

0.4*7 = 2.8

x = 2.8

Answer:

x=2.8

Step-by-step explanation:

one side is divided by seven, lets undo that by multiplying both sides by 7

x/7=0.4

*7      *7

x=2.8

Answer:

f=3

Step-by-step explanation:

The intervals means that angle f is between the quadrant 1.

Using that, we can use this identity

[tex] \sin(x) = \cos(y) [/tex]

where x+y=90

[tex]22f - 1 + 7f + 4 = 90[/tex]

[tex]29f + 3 = 90[/tex]

[tex]29f = 87[/tex]

Step-by-step explanation:

Answer:

(0.5, 1)

Step-by-step explanation:

The coordinates of the image of the point D (0.5, 2 ) are 0.5 and 2.

A coordinate plane is a 2D plane which is formed by the intersection of two perpendicular lines known as the x-axis and y-axis.

Given that:-

The image of point D ( 0.5 , 2 ) is given so the coordinates of the point will be 0.5 and 2.

Hence the coordinates of the image of the point D (0.5, 2 ) are 0.5 and 2.

Answer: 200 grams.

Step-by-step explanation:

80 x 5 = 400

400 divided by 2 = 200.

We need to find how much 5 oranges weighs by multiplying 80 by 5.

80x5=400

So 5 oranges weighs 400 grams. We also need to find the weight of one grapefruit. Since 5 oranges, or 400 grams, weigh the same as 2 grapefruits, we need to divide 400 by 2.

400/2=200

So each grapefruit weighs 200 grams.

Step-by-step explanation:

Answer:

I got 4 units

Step-by-step explanation:

The perimeter of the new rectangle  is 23cm

Formula for perimeter is given by

Perimeter = 2(length  + width)

Perimeter = 2( 6 + 4)

Perimeter = 2 × 10

Perimeter = 20cm

If the length and width are enlarged by 1/2, we have

Perimeter  = 2( 6 + 4 +1/2)

Perimeter = 2( 10 + 0.5)

Perimeter = 2× 11. 5 = 23cm

Thus, the perimeter of the new rectangle  is 23cm
