a. How many cubes with an edge length of b. What is the volume, in cubic inches, of inch are needed to build a cube with one cube with an edge length of inch? an edge length of 1 inch?

Answers

The number of cubes of edge length 1/3 is 27 and the volume of the cube is 1 cubic inches

How to determine the number of cubes

From the question, we have the following parameters that can be used in our computation:

Edge length of cube 1 = 1/3 inchEdge length of cube 2 = 1 inch

The volume of a cube is the cube of its edge length

This means that the volumes are

Volume = Edge length³

So, we have

Volume of cube 1 = (1/3 inch)³ = 1/27 cubic inches

Volume of cube 2 = (1 inch)³ = 1 cubic inch

The number of cubes is then calculated as

Number of cubes = Volume of cube 2/Volume of cube 1

This gives

Number of cubes = 1/(1/27)

Number of cubes = 27

The volume of the cubes

Here, we have

Edge length of cube = 1 inch

The volume of a cube is the cube of its edge length

This means that the volumes are

Volume = Edge length³

So, we have

Volume of cube = (1 inch)³ = 1 cubic inch

Answers

Answer: $4.5 left.

Step-by-step explanation:

You have 30 quarters, and find 20% more. To convert percentages to decimals for calculations, simply move the decimal two spaces to the left.

20% is 20. ---> 2.0 ---> .20

30 * 0.2 = 6. Now add 6 (found) to 30 (original) to get the total.

30+6 = 36 total quarters.

You spend 50% of the quarters, 36 * 0.5 = 18.

This means you have 18 quarters left (or you spent 18).

18 quarters, each quarter is worth 0.25 dollars, so multiply the number left by how much each is worth.

18 * 0.25 = $4.5.

$4.50 is the amount left

The option that describes the graph of the proportional relationship is the option;

A line passes through the point (0, 0) and continues through the point (15, 5).

What is a proportional relationship?

A proportional relationship is one in which one variable in the relationship is a constant multiple of the other variable.

The table of values can be presented as follows;

x; 15 9 21

y; 5 3 7

The domain of the function is therefore; 15, 9, 21

The range of the function is therefore; 5, 3, 7

The coordinates of points on the graph of the function is therefore;

(15, 5), (9, 3), (21, 7)

The relationship between the xi and y-values of the function is therefore;

5/15 = 3/9 = 7/21 = 1/3

The constant of proportionality in the relationship is 1/3

The relationship is therefore a proportional relationship.

The characteristics of the graph of a proportional relationship includes;

The graph passes through the origin, (0, 0).

The correct option that therefore describes the graph is the option;

A line passes through the point (0, 0), and continues through the point (15, 5)

The width of a rectangle is 4 more than the length. If the perimeter is 36 cm, ind the dimensions (length and width) of the rectangle.

Answers

Answer with step-by-step explanation:

Let the width of the rectangle be x.

Given that,

length ⇒ 4

width ⇒ x + 4 ( Because, the rectangle's width is 4 more than the length.)

Perimeter ⇒ 36cm

The formula to find the perimeter of rectangle is:

P = 2 ( l + w )

Now to find the value of x replace P, l & w with 36, 4 & (x + 4) with respectively.

P = 2 ( l + w )

36 = 2 ( 4 + x + 4 )

36 = 2 ( x + 8 )

Solve the brackets.

36 = 2x + 16

Substract 16 from both sides.

36 - 16 = 2x

20 = 2x

Divide both sides by 2.

10 = x

And now let us find the exact dimensions of the rectangle.

Length = 4 cm

Width = x + 4 = 10 + 4 = 14 cm

Given points:

(-4, 3)(6, 1)(1, -4)(-3, -5)

To find the equations for each of the lines:

Find the slope of the line by substituting two points on the line into the slope formula.Substitute the found slope and one of the points on the line into the point-slope formula and simplify.

Line #2

Points:

Let (x₁, y₁) = (6, 1)Let (x₂, y₂) = (1, -4)

Find the slope:

[tex]\implies \textsf{slope}\:(m)=\dfrac{y_2-y_1}{x_2-x_1}=\dfrac{-4-1}{1-6}=\dfrac{-5}{-5}=1[/tex]

Substitute the found slope and one of the points into the point-slope formula:

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

[tex]\implies y-1=1(x-6)[/tex]

[tex]\implies y=(x-6)+1[/tex]

[tex]\implies y=x-5[/tex]

Line #3

Points:

Let (x₁, y₁) = (1, -4)Let (x₂, y₂) = (-3, -5)

Find the slope:

[tex]\implies \textsf{slope}\:(m)=\dfrac{y_2-y_1}{x_2-x_1}=\dfrac{-5-(-4)}{-3-1}=\dfrac{-1}{-4}=\dfrac{1}{4}[/tex]

Substitute the found slope and one of the points into the point-slope formula:

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

[tex]\implies y-(-4)=\dfrac{1}{4}(x-1)[/tex]

[tex]\implies y+4=\dfrac{1}{4}(x-1)[/tex]

[tex]\implies y=\dfrac{1}{4}(x-1)-4[/tex]

Line #4

Points:

Let (x₁, y₁) = (-3, -5)Let (x₂, y₂) = (-4, 3)

Find the slope:

[tex]\implies \textsf{slope}\:(m)=\dfrac{y_2-y_1}{x_2-x_1}=\dfrac{3-(-5)}{-4-(-3)}=\dfrac{8}{-1}=-8[/tex]

Substitute the found slope and one of the points into the point-slope formula:

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

[tex]\implies y-(-5)=-8(x-(-3))[/tex]

[tex]\implies y+5=-8(x+3)[/tex]

[tex]\implies y=-8(x+3)-5[/tex]

[tex]\implies y=-8x-24-5[/tex]

selling price of car if rs 50,000 , profit is 10% and cost price of car will be ?

Answers

Answer:

Rs 45,000

Step-by-step explanation:

The profit is the difference between the selling price and the cost price of the car. In this case, the profit is 10% of the selling price, or 10% * Rs 50,000 = Rs 5,000.

Therefore, the cost price of the car is the selling price minus the profit, or Rs 50,000 - Rs 5,000 = Rs 45,000. This is the amount that the seller paid for the car, before adding the profit.

Answers

The category which has the greatest joint frequency is sugar cookies with a frequency of frosting and no frosting as 56 and 120 and a joint frequency of 176

Which category has the highest joint frequency?

Frosting No frosting Total

sugar cookies 56 120 176

Chocolate cookie 66 70 136

Red velvet 38 50 88

Total 160 240 400

Chocolate cookies with frosting = Total chocolate cookies - chocolate cookies with no frosting

= 136 - 70

= 66

Red velvet cookies with frosting = Total cookies with frosting - (Chocolate cookies with frosting + sugar cookies with frosting)

= 160 - (56 + 66)

= 160 - 122

= 38

Total red velvet cookies = Red velvet cookies with frosting + Red velvet cookies with no frosting

= 50 + 38

= 88

Total cookies with no frosting = Total cookies - Total cookies with frosting

= 400 - 160

= 240

Total sugar cookies with no frosting = Total cookies with no frosting - (chocolate cookies with no frosting + Red velvet cookies with no frosting)

= 240 - (70 + 50)

= 240 - 120

= 120

Total sugar cookies = Total sugar cookies with no frosting + Total sugar cookies with frosting

= 120 + 56

= 176

In conclusion, the highest joint frequency is sugar cookies.

What is simple interest?

Simple interest is defined as the amount of interest paid on a specific principal, an amount at a specific interest rate. It is given by

I = Prt

where, I = simple interest, P = Principal, r = rate of interest, t = time taken

Given, P = $100

I = $135

r = 0.15

t = ?

So, simple interest is given by:

I = Prt

or, 135 = 100*0.15*t

or, 135 = 15*t

or, t = (135/15) = 9 years = 9*12 = 108 months

The half-life of a drug in the bloodstream is 14 hours. What fraction of the original drug dose remains in 36 hours? in 72 hours?
What fraction of the original drug dose remains in 36 hours?
(Do not round until the final answer. Then round to the nearest hundredth as needed.)

Answers

16.82 % and 2.83% of the original drug dose remain in 36 hours and 72 hours respectively.

What is half-life?

Half-life is a characteristic unit for the exponential decay equation and is constant across the lifespan of an exponentially decaying quantity.

Given, the half-life of a drug(h) = 14 hours

The first condition, time duration (t) = 36 hours

Then, the half-life of the substance can be calculated by:

[tex]A = A_{0} * (1/2)^{\frac{t}{h} }[/tex]

or, [tex]A = A_{0} * (1/2)^{\frac{36}{14} }\\A = A_{0} * (0.1682)\\[/tex]

16.82 % of the original drug dose remains in 36 hours

Hence, 16.82 % of the original drug dose remains in 36 hours

The second condition, time duration (t) = 72 hours

Then, the half-life of the substance can be calculated by:

[tex]A = A_{0} * (1/2)^{\frac{t}{h} }[/tex]

[tex]A = A_{0} * (1/2)^{\frac{72}{14} }\\A = A_{0} * (0.0283)\\[/tex]

2.83 % of the original drug dose remains in 72 hours

Hence, 2.83 % of the original drug dose remains in 72 hours
