Answer:

C.

Step-by-step explanation:

Replace y with each value.

If y is 2 then the answer would be -2

If y is 4 then the answer would be -1

If y is 8:

8/2 = 4

The answer is D. 7x + 11x = 90

Answer:

10+2x= the sum (anything could be put here)

Step-by-step explanation:

Well sum is automatically addition

Doubleing a number is basically multiplying it by 2

so

10+2x= whatever youw ant to put here

Answer:

(a) The area is 0.03 square miles

(b) The population density is 12000 people per square miles

Step-by-step explanation:

Given

See attachment for complete question

Solving (a): Area of Orchid Hill (in square miles)

The dimension of the neighborhood is 4 blocks by 3 blocks

Since each block are of the same dimensions

The area is calculated as:

[tex]Area = 4blocks * 3 blocks[/tex]

If [tex]20\ blocks = 1\ mile[/tex] then:

[tex]1\ block = \frac{1}{20} mile[/tex]

[tex]1\ block = 0.05mile[/tex]

So, we have:

[tex]Area = 4blocks * 3 blocks[/tex]

[tex]Area = 4 * 0.05 * 3 * 0.05[/tex]

[tex]Area = 0.03mi^2[/tex]

Solving (b): The population density of the neighborhood as people per square mile

From the question, we have:

[tex]People = 360[/tex]

[tex]Area = 0.03mi^2[/tex] --- calculated

So, the population density is:

[tex]Density = \frac{People}{Density}[/tex]

[tex]Density = \frac{360}{0.03}[/tex]

[tex]Density = 12000[/tex]

Answer:

The answer is 493.3

Step-by-step explanation:

6.72 x 12.7 x 5.78 = 493.28872

And 493.28872 rounded to the nearest tenth is 493.3 because the original number in the tenth place is 2 and then the digit before that is 8 which in this case is your rounding digit. Round up If the number is greater than 5 and round down if its less than 5. In this case its greater than 5 to that leaves you with 28 so now you have 493.28, 28 rounded to the nearest tenth is 30 and just take the 0 away, as if it didn't exist.

The surface area of the prism is 395 square centimeter.

Volume is a collection of two - dimensional points enclosed by a single dimensional line. Mathematically, we can write volume as -

V = ∫∫∫ F(x, y, z) dx dy dz

Given is to fins the surface area of the prism given below.

The given prism is a cuboid. We can write the surface area of the cuboid as -

V = 2(LB + BH + LH)

V = 2(12.7 x 5.78 + 5.78 x 6.72 + 12.7  x 6.72)

V = 2(73.4 + 38.8 + 85.344)

V = 395 square centimeter

Therefore, the surface area of the prism is 395 square centimeter.

Answer:

5 lol

Step-by-step explanation:

Answer:

5 im so smart :)

Step-by-step explanation:

Answer and Step-by-step explanation:

Yes, all of your calculations are correct!!

The area of one rectangle is 192, and since there are 2 rectangles, we multiply 192 by 2, which results in 384.

The area of a triangle is [tex]A = \frac{(Height)(Base)}{2}[/tex], which you got to be 96.

The Semi Circle would have half of the area of a circle, so you are correct when you multiply the equation by [tex]\frac{1}{2}[/tex].

To find that diameter, we need to use the Pythagorean Theorem.

[tex]12^{2} + 16^{2} = d^{2} \\\\144 + 256 = d^{2} \\\\400 = d^2\\\\d = 20[/tex]

So the diameter is 20, and the radius is 10 (20 divided by 2 = radius).

Plug that into the equation, and you get the answer to be [tex]50\pi[/tex], or 157.0796327.

157.0796327 + 384 + 96 = 637.08 (rounded to the nearest hundredth).

Answer:

y= x-3

Step-by-step explanation:

use the slope formula which is y= m(slope)x + b(y intercept)

The slope is one, so you can just leave it as x, and the y intercept is -3 so you can plus that into the b.

Answer: 84.14

Step-by-step explanation:

Area of the rectangle is L*W=B*H

14*5=70

To find the area of the half circle we must use the formula pi r^2/2

r=radius

and the radius is 6 because we add 4 and 4 and need to get to 14

because the line below it is 14 and it is a rectangle so the lengths are the same.

Diameter=6

So radius =3

pi (3)^2/2=

9/2 pi + 70=

Answer: 84.13

lmk if this is wrong

Step-by-step explanation:

Area of the rectangle:

5(14)=70

Area of the half circle:

Formula: πr^2

Substitute: 3.14(3)^2

Solve: 3.14(9)

3.14(9)=28.26

Divide the area by 2 since it's a half circle

28.26/2=14.13

Add the area of the rectangle and half circle

70+14.13=84.13
