0.29629629629in³

Step-by-step explanation:

To find the volume of a cube you multiply the length by the width by the height. Since all the sides of the cube are the same, its the same measure multiplied three times, ie. to the power of three.

(2/3)³=0.29629629629in³

Answer:

39,055

Step-by-step explanation:

so you say 6 over 100 multiplied by $36,500 over 1. then 100 into 36,500 then you get 365. then you say 6 multiplied by 365 and you get 2,555. then you say 2,555 plus 36,500 then you get 39,055

Step-by-step explanation:

Answer:

a.) x²+h²+2xh-8x-8h

b.) h+2x-8

Step-by-step explanation:

A.) you just plug in x+h wherever there's an x

which means you have

(x+h)²-8(x+h)

simplify and get

x²+h²+2xh-8x-8h

we already know what f(x+h) is so we just need to subtract f(x) we have

x²+h²+2xh-8x-8h-x²+8x

simplify and get

h²+2xh-8h

Divide this by h and get

h+2x-8

Answer:

h+2x-8

Answer:

11 [tex]\frac{3}{8}[/tex] miles.

Step-by-step explanation:

To find how many miles Brandon rode, we can create an equation in slope-intercept form: y = mx + b

$2.25 is the flat fee, or the unchanging variable. This is our y-intercept, or b.

$0.40 is the changing variable, as it changes value depending on the amount of miles ridden. This is our slope, or m.

We know Brandon spent $6.80 on the cab ride. So, this is our y.

We get the equation: 6.80 = 0.40x + 2.25.

To solve, first subtract 2.25 from both sides of the equation:

6.80 - 2.25 = 0.40x + 2.25 - 2.25

We get: 4.55 = 0.40x

Now, just divide by 0.40 on both sides:

4.55 ÷ 0.40 = 0.40x ÷ 0.40

We get: 11.375 = x

So, Brandon rode for 11.375 miles. When converted to a mixed number, we get 11 [tex]\frac{3}{8}[/tex] .

Answer:

Area = 396 units²

Step-by-step explanation:

Let's assume:

Length = 2c - 5

Width = 5c + 9

Perimeter = 2(L + W) = 106 units

Thus:

2[(2c - 5) + (5c + 9)] = 106

Find the value of c

2[2c - 5 + 5c + 9] = 106

2[7c + 4] = 106

14c + 8 = 106

14c = 106 - 8

14c = 98

Divide both sides by 14

c = 98/14

c = 7

✔️Area of the rectangle = Length × Width

Area = (2c - 5)(5c + 9)

Plug in the value of c

Area = (2×7 - 5)(5×7 + 9)

Area = (14 - 5)(35 + 9)

Area = (9)(44)

Area = 396 units²

Answer:

There's a proportion relationship between number of shell and their cost

Step-by-step explanation:

The graph is not given.

However, I've added the appropriate graph as an attachment.

From this, point....

I'll show that the cost and number of shells as given in the question are proportional.

Represent cost with y and number of shells with x

x = 2 when y = 0.8

x = 3 when y = 1.2

x = 4 when y = 1.6

Divide each value of y by x to get the constant of proportion (r).

r = y/x

r = 0.8/2 = 0.4

r = 1.2/3 = 0.4

r = 1.6/4 = 0.4

Notice that the values of r remain constant.

Hence, there's a proportion relationship between both

And what this rate represent is that:.the cost of shell changes at a constant rate when the number of shell is changes.

Answer:

[tex]y = -\frac{5}{2}x +6[/tex]

Step-by-step explanation:

Given

[tex]m = -\frac{5}{2}[/tex] -- slope

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

Required

Determine the line equation

In slope intercept form, a line equation is:

[tex]y - y_1 = m(x - x_1)[/tex]

This gives:

[tex]y - 1 = -\frac{5}{2}(x - 2)[/tex]

Open bracket

[tex]y - 1 = -\frac{5}{2}x +5[/tex]

Add 1 to both sides

[tex]y - 1+1 = -\frac{5}{2}x +5+1[/tex]

[tex]y = -\frac{5}{2}x +6[/tex]

∠DGB = 101°

Step-by-step explanation:

Given:

∠CGB = 79°

Find:

∠DGB

Computation:

We know that CD is a straight line

So,

∠CGB + ∠DGB = 180

79 + ∠DGB = 180

∠DGB = 101°

Answer:

2 hours

Step-by-step explanation:

To solve this question, we can convert the fraction into decimal form momentarily, so that 5 1/2 is now 5.5, and 3 1/2 is now 3.5. We know that Sara has already driven 3.5 hours, and it takes 5.5 to get to her aunts house. To dins how much longer Sara has left to drive, simply subtract the total amount of hours by the hours already completed:

5.5 - 3.5 = 2.0

Meaning, Sara has 2 hours left to drive

Hope this helps :)

Answer:

The temperature of the water when the first race started was 78.1 degrees

Step-by-step explanation:

Addition

The temperature of the water of a pool was 72.5 degrees when the swimmers first arrived.

By the time when the first race started, the temperature had increased by 5.6 degrees.

To find the temperature at that very moment we have to add 72.5 degrees + 5.6 degrees = 78.1 degrees

The temperature of the water when the first race started was 78.1 degrees

what kind of math is this X_X

The value of P for the given angles of the quadrilaterals is 6.

One of the earliest areas of mathematics is geometry, along with arithmetic. It is concerned with spatial characteristics like the separation, shape, size, and relative placement of objects.

Given that the two opposite angles are 4P + 12 and 36 respectively.

The value of P for the two opposite angles will be calculated as:-

4P + 12 = 36

4P = 36 - 12

4P = 24

P = 24 / 4

P = 6

Hence, the value of P for the given angles of the quadrilaterals is 6.

Answer:

x = 20

Step-by-step explanation:

4(x + 7) - 5x + 2 = 10

open the parenthesis

4 * x + 4 * 7 - 5x + 2 = 10

4x + 28 - 5x + 2 = 10

combine like terms

-x + 30 = 10

subtract 30 from both sides of the equation

-x + 30 - 30 = 10 - 30

-x = 10 - 30

-x = -20

mutiply the equation by -1

-1 * -x = -20 * -1

x = 20
