Answer:

210 in.

Step-by-step explanation:

Volume of a box = V = length x width x height

You don't have to know which number is the length, width and height since you are multiplying all of them together anyways.

V = 7in x 10in x 3in

V = 210 in

The volume of the box 210 cubic inches.

The volume of a cuboid is defined as the total number of cubic units occupied by the cuboid completely. A cuboid is a three-dimensional solid figure, having 6 square faces. Volume is nothing but the total space occupied by an object.

The dimensions of given box is length=7 inches, width=10 inches and height=3 inches.

We know that, volume of cuboid is length×width×height

Now, volume =7×10×3

= 210 cubic inches

Therefore, the volume of the box 210 cubic inches.

The area of the shaded region is 123.84 cm²

A circle is a shape consisting of all points in a plane that are at a given distance from a given point, the centre.

The side length of the square is a= 24 cm

Area of square = a²

=24²

=576 cm²

Now let us find the area of circle

Diameter of circle is 24cm

Radius=24/2=12 cm

Area of circle=πr²

=3.14×12²

=3.14×144

=452.16cm²

the area of the shaded region = 576-452.16

=123.84 cm²

Hence, the area of the shaded region is 123.84 cm²

Step-by-step explanation:

The length of the rectangle is 7 cm and the width is 5 cm.

The whole distance covered by the rectangle's borders or its sides is known as its perimeter. As we know the rectangle will have 4 sides then the perimeter of the rectangle will be equal to the total of its four sides. And the unit will be in meters, centimeters, inches, feet, etc.        

The formula for the Perimeter of the rectangle is given by

Here we have

The length of a rectangle is 2cm greater than the width of the rectangle

And perimeter of the rectangle = 24 cm

Let x be the width of the rectangle

From the given data,

Length of the rectangle = (x + 2) cm  

As we know Perimeter of rectangle = 2(Length+width)

=> Perimeter of rectangle = 2(x+2 + x) = 2(2x +2)

From the given data,

Perimeter of rectangle =  24cm

=> 2(2x +2) = 24 cm

=> (2x +2) = 12     [ Divided by 2 into both sides ]

=>  2x = 12 - 2

=>  2x = 10

=>   x = 5         [ divided by 2 into both sides ]  

Length of rectangle, (x+2) = 5 + 2 = 7 cm

Therefore,

The length of the rectangle is 7 cm and the width is 5 cm.

The amount of substance left after 8 days will be approximately X units rounded to the nearest whole number.

Given that the amount of substance decreases exponentially, we can use the exponential decay formula to determine the amount present at a specific time.

The general form of the exponential decay formula is: A = A₀ * e^(-kt)

Where:

A₀ is the initial amount (183 units)

A is the amount at time t

k is the decay constant

t is the time in days

We are given that the amount at t = 2 days is 176 units. Plugging these values into the equation, we can solve for the decay constant (k):

176 = 183 * e^(-2k)

To solve for k, divide both sides by 183 and take the natural logarithm:

ln(176/183) = -2k

Solving for k: k ≈ ln(183/176) / 2

Now we can find the amount at t = 8 days. Plugging in the values:

A = 183 * e^(-k * 8)

Substituting the value of k: A ≈ 183 * e^(-8 * ln(183/176) / 2)

Calculating the expression will give us the amount of substance left after 8 days, which should be rounded to the nearest whole number.

Each equation has the same rate as well

The mean of all exam scores in the class is 72.67 ~ 73 . Mean is ratio of sum of score in all exam to the total numbers of all exams.

The exam scores are normally distributed , normally distributed is an arrangement in which most of values in middle and rest are symmetrically distributed at the ends 80th percentile of scores earned 85 it implies that 80% of students score is 85 or less and 30th percentile of scores earned 65 means 30% of students score is 65 or less .

Z-score value for 80th percentile is 0.841

Z-score value for 30th percentile is – 0.524

Formula for normally distributed,

Z =( X – μ) / σ

where μ is mean of scores , σ is standard deviations of scores ,X is sample mean

For 80th percentile , X= 85 , Z= 0.841

0.841=( 85- μ) /σ ----(1)

-0.524= (65-μ) / σ ----(2)

Solving equations (1) and (2)

- (841/524)= (85-μ )/( 65-μ) => 841μ – 841(65) = -524μ +85(524)

⇒ 1365μ= 99,205 => μ= 72.67

So, the value of mean of scores obtained by students in a class is 72.67 ~ 73

104 beats is multiplied with the decimal of the fraction of beats and measures which means it has been used with whole numbers

0.125 is not a whole number we know x 100 is 12.5 and we know x4 is 0.5

Use PEMDAS to solve

The probability of first tile is less than 15, is 70% and the second tile is even or greater than 25, is 60%.

In the given question we have to find the probability of first tile is less than 15 and the second tile is even or greater than 25.

Tiles numbered 1 through 20 are placed in a box.

Tiles numbered 11 through 30 are placed in a second box.

One tile is randomly drawn from each box.

Now finding the probability of first tile is less than 15.

Since in first box tile is numbered as 1 to 20.

So the outcomes of less than 15 = 1, 2, 3, 4, 5, 6, 7, 8, 9, 10, 11, 12, 13, 14

So favourable outcome = 14

Total number of tile = 20

So the probability = 14/20 = 70%

Now finding the probability of second tile is even or greater than 25.

Since in second box tile is numbered as 11 to 30.

So the outcomes of even or greater than 25 = 12, 14, 16, 18, 20, 22, 24, 26, 27, 28, 29, 30

So favourable outcome = 12

Total number of tile = 20

So the probability = 12/20 = 60%

Hence, the probability of first tile is less than 15, is 70% and the second tile is even or greater than 25, is 60%.

For given equation of circle radius is 6 unit and center is at (-2,1).

What is a circle?

A circle is a special kind of ellipse in which the eccentricity is zero and the two foci are coincident. A circle is also termed as the locus of the points drawn at an equidistant from the center. The distance from the center of the circle to the outer line is its radius. Diameter is the line which divides the circle into two equal parts and is also equal to twice of the radius.

The equation of circle in the plane is given as:

(x-h)^2 + (y-k)^2 = r^2

where (x, y) are the coordinate points

(h, k) is the coordinate of the center of a circle

and r is the radius of a circle.

Now,

As shown in graph the graph by taking two points on graph

Let C = cost to rent each chair

Let T = cost to rent each table

4C + 8T = 73

2C + 3T = 28

Multiply the 2nd equation by (-2) and then add the equations together  

4C + 8T = 73

-4C - 6T = -56

2T = 17

T = 17/2 = 8.5

Plug this in to the 1st equation to solve for C

4C + 8(17/2) = 73

4C + 68 = 73

4C = 5
