Final answer:

Each container will have approximately 3.75 kilograms of rice, which can be expressed as 3.75 kg or 15/4 kg.

Explanation:

To find out how many kilograms of rice are in each container, we need to divide the total weight of the rice by the number of containers. In this case, we have 15 kilograms of rice and 4 containers, so we divide 15 by 4. The result is 3.75 kilograms.

So, each container will have 3.75 kilograms of rice.

As a decimal, this can be expressed as 3.75 kg. As a fraction, it can be written as 15/4 kg.

Answer:

(5B+C-2A)/8 = x

Step-by-step explanation:

2A - 5B + 4X = C - 8X

subtract 4x from both sides

2A - 5B + 4X-4x = C - 8X-4x

2A - 5B = C - 12X

subtract C from both sides

2A - 5B -C = C-C - 8X

2A - 5B -C = - 8X

divide both sides by -8

(2A - 5B -C)/-8 = - 8X/-8

(-2A+5B+C)/8 = x

(5B+C-2A)/8 = x

Answer:

x=50 ∠BCX=65

Step-by-step explanation:

The angles is a triangle add up to 180 so

70+45+∠BCX=180 so

115+∠BCX=180 (subtract 115 from both sides)

∠BCX=65

A line adds up to 180

so 2x+15+65=180

so 2x+80=180 (subtract 80 from both sides)

2x=100 (divide by 2)

x=50

Answer: 0.6x = 87

Step-by-step explanation:

Hi, to answer this question we have to write en equation:

We have to multiply the variable x by the percentage given (60%) in decimal form (divided by 100). That expression must be equal to 87.

Mathematically speaking:

x (60/100) = 87

0.6x = 87

Feel free to ask for more if needed or if you did not understand something.

This equation states that 60% (or 0.60) of x is equal to 87.

To express the relationship between 60% of x and 87, we can set up an equation. Since 60% can be written as 0.60, we can write:

0.60x = 87

To solve for x, we divide both sides of the equation by 0.60:

x = 87 ÷ 0.60

So, x will be:

x = 145

This shows that 60% of 145 is equal to 87.

The volume of a cylinder with a base diameter of 8ft and height of 20ft is approximately 1005.3 cubic feet.

The volume of a cylinder can be calculated using the formula Volume = πr²h where π represents approximately the number 3.14, 'r' signifies the radius of the cylinder, and 'h' denotes the height of the cylinder.

In this case, the diameter of the cylinder is given as 8 feet, so the radius will be half of that which is 4 feet. The height is specified as 20 feet.

Substitute these values into the equation:

Volume = π * (4 ft)² * 20 ft

This simplifies to:

Volume = 3.14 * 16ft² * 20ft

By multiplying these values, we get the volume equals the product of these numbers:

Volume ≈ 1005.3 cubic ft. Hence, the volume of this cylinder to the nearest tenths is 1005.3 cubic feet.

SPJ3

The volume of a cylinder with an 8ft diameter and 20ft height is approximately 1005.3 cubic feet, rounded to the nearest tenths place.

To calculate the volume of a cylinder, we use the formula V = πr²h, where V represents the volume, r is the radius of the cylinder's base, and h is the height of the cylinder. Given that the diameter of the cylinder is 8ft, the radius is half of the diameter, which is 4ft. Now, using the formula:

V = πr²h

V = π(4ft)² × 20ft

V = π16ft² × 20ft

V = π 320ft³

V = 1005.31ft³

Therefore, the volume of the cylinder is approximately 1005.3 cubic feet, rounded to the nearest tenths place.

Answer:

[tex]36\pi -18\sqrt{7}[/tex]

Step-by-step explanation:

Every inscribed right triangle has its hypotenuse as the same size of the Diameter. Assuming that, this is the case check the picture below.

So the hypotenuse= D=2R=12

[tex]A_{circle}=\pi (6)^{2}=36\pi[/tex]

Finding the Triangle base via the Pythagorean Theorem

[tex]a^2=b^2+c^2\\12^2=9^2+c^2\\144-81=c^2\\c=\sqrt{63}\\c=3\sqrt{7}\approx 7.94[/tex]

Now plugging in the base of the triangle on that formula:

[tex]A=\frac{bh}{2}\\A=\frac{3\sqrt{7}*12}{2}\\A=18\sqrt{7}[/tex]

Finally,

Shaded Area = [tex]36\pi -18\sqrt{7} cm^{2} \approx 65.48 cm^{2}[/tex]

Answer: The density is 0.002 lb/cm^3

Step-by-step explanation:

1 BTU is neded to increment the temperature of 1 Lb of water by 1° F

Then if we need 41.7 BTU to increment 1°F of 5 gallons of water, this means that in the 5 gallons we have a mass of 41.7 lbs of water.

And as you know, density = mass/volume

now, 1 gallon = 3.78 liters = 3780 cm^3

then 5 gallons = 5*3780 cm^3  = 18900 cm^3

The density is D = 41.7Lb/18900 cm^3 = 0.002 lb/cm^3

Answer:

u = 5/4

Step-by-step explanation:

to evaluate for the value of u we would simply open the bracket and then evaluate for the value of u by collecting the like terms together.

solution

3=7(4 - 2u)-6u

3 = 28- 14u - 6u

collect the like terms

3 + 14u + 6u = 28

20u = 28 - 3

20u = 25

divide both sides by the coefficient of u which is 20

20u/20 = 25/20

u = 5/4

Answer:

[tex]u = 5/4[/tex]

Step-by-step explanation:

Step 1:  Distribute on the right side

[tex]3 = 7(4 - 2u) - 6u[/tex]

[tex]3 = (7 * 4) + (7 * -2u) - 6u[/tex]

[tex]3 = 28 - 14u - 6u[/tex]

Step 2:  Combine like terms

[tex]3 = 28 + (-14u - 6u)[/tex]

[tex]3 = 28 + -20u[/tex]

Step 3:  Subtract 28 from both sides

[tex]3 - 28 = 28 - 20u - 28[/tex]

[tex]-25 = -20u[/tex]

Step 4:  Divide both sides by -20

[tex]-25 / -20 = -20u / -20[/tex]

[tex]5/4 = u[/tex]

Answer:  [tex]u = 5/4[/tex]

Answer:

11 in

Step-by-step explanation:

Starting with the base, we know the side length is 5 inches. So with that in mind, we can do 5 x 5 to get the area of the base, 25. We also know the volume of the whole rectangular prism is 275, so we can do 275 ÷ 25. The quotient of that is 11.

We can check our answer by doing 11 x 25. This gives us 275, proving that it is correct.

Answer:

(8.2) (8.2) + 4 (one-half (8.2) (11.1))

Step-by-step explanation:

Formula for calculating the surface area of a square based pyramid is expressed as:

Surface area = A + 1/2ps

A is the base area

P is the perimeter of base

S is the slant side.

Since the base of the pyramid is a square, then

Base Area A = L²

A = 8.2²

A = 67.24cm²

Perimeter of square = 4L = 4(8.2)

= 32.8cm

Slant Height = 11.1cm

On substituting the gotten value:

Surface area = 8.2(8.2) + 1/2 [4(8.2 (11.1)]

Answer:

The third one is correct, the others bend the truth as they can touch but not overlap. As the third one states 'They are organized in equal intervals.'  this means they share an equal growth opportunity within their own column, their own height and nominated place within the histogram. The bars are of equal width and correspond to the equal class intervals. But on rare occasions like size classes they can be shown as a wider variant within their groups. Example would be showing a wider column say on classes at a school as the width and data being achieved forces a true event of variant sizes in education upon the base of the graph, this rarely applies to staff graphs as planning for schools is a wider data share than say offices using these types of graphs. Work development would use just data percentages along with the frequencies is one example so group size are stated in the reports to support more specific data in the graphs instead.

To display numerical data that has been organized into equal intervals. The bars should touch the adjacent bars but not overlap. These intervals allow you to see the frequency distribution of the data, or how many pieces of data are in each interval.
