Answer:

600 cm²

Step-by-step explanation:

let x = length of a side of the cube

all sides are equal in a cube

Volume = x³ = 1000 cm³

x = ∛1000 = 10 cm

Area of 1 side = 10cm x 10cm = 100 cm²

There are 6 equal sides in a cube

SA = 6(100) =  600 cm²

Therefore , the solution of the given problem of fraction comes out to be Roman can thus perform 8 poster.

Any number of equal amounts or fractions can be used to represent a whole. In standard English, the quantity of a certain size is stated as a fraction. 8, 3/4. Wholes also include ratio. Numbers are represented in mathematics by the fraction to numerator ratio. These are all straightforward integer fractions. There is a fraction in the denominator of a difficult fraction. because the calculations, numerators, and numerators of actual fractions vary.

Here,

Given :

Roman divided a poster board sheet into ten equally sized pieces.

The entire sheet should be x.

then, one part of sheet=  1/1 0 of the sheet

Currently, only 8/10 of the poster is left after his brother used portion of it.

Roman can therefore use each remaining piece of the poster to create a sign if he so chooses.

The number of indications he is capable of making is then

=> 8/10/1/10

= > 8/10 * 10 = 8.

Roman can thus perform 8 signs.

Therefore , the solution of the given problem of fraction comes out to be

Fractions are represented as numerical value, which defines a part of a whole. A fraction can be a portion or section of any quantity out of a whole, where the whole can be any number, a specific value, or a thing

In order to find how many pounds of apples she has left, subtract the apple she sold from the apple she begins with. That is:

Apple left = 35 1/2 - (35 1/2 * 1/2) - (35 1/2 *4/19) - (35 1/2 * 1/4 )

In the United States, 65% of cans are recycled.

A number or ratio that can be expressed as a fraction of 100 is called a percentage. Divide the number by its whole number and multiply it by 100 if we have to figure out the percentage of that number. Consequently, the percentage represents one part per hundred.

Given In the United States, 13 out of every 20  cans are recycled.

total cans = 20

recycled cans = 13

percent of recycled can = 100*recycled cans/total cans

The dimensions that will maximize the enclosed area are 125 meters by 250 meters

Represent the dimensions with x and y

So, we have the following equations

Perimeter = 4x + 2y = 1000

Area = 2xy

So, we have

2x + y = 500

This gives

y = 500 - 2x

So, we have

Area = 2x(500 - 2x)

Expand

Area = 1000x - 4x^2

Differentiate and set to 0

1000 - 8x = 0

So, we have

8x = 1000

Divide

x = 125

Recall that

y = 500 - 2x

y = 500 - 2 * 125

y = 250

Hence, the dimension is 125 by 250

The requried area of 3 of the pieces is 231 square feet. Option B is correct.

The area of a circle is the amount of space enclosed by the circle in a two-dimensional plane. It is given by the formula:

A = πr²

where "A" is the area of the circle, "r" is the radius of the circle, and "π" (pi) is a mathematical constant with an approximate value of 3.14159.

Here,
The area of a full circle with a radius of 14 feet is given by:

A = πr²

A = (22/7) × (14)²

A = (22/7) × 196

A = 616 square feet (rounded to the nearest whole number)

If the circle is cut into 8 equal pieces, each piece will have an area of:

616 ÷ 8 = 77 square feet

Therefore, 3 pieces will have an area of 3 × 77 = 231 square feet.

Thus, the requried area of 3 of the pieces is 231 square feet. Option B is correct.

Answer:

Step-by-step explanation:

The lateral surface area of the pyramid can be found using the formula for the area of an equilateral triangle:

A = (s^2 * √3) / 4

where s is the length of one side of the equilateral triangle base.

For this pyramid, s = 50 feet

A = (50^2 * √3) / 4 = (2500 * √3) / 4 = 1250 * √3 ≈ 2129.28 ft^2

The total surface area of the pyramid can be found by adding the area of the base to the area of the lateral surface:

A = base area + lateral surface area

A = (side length^2 * √3) / 4 + (3 * triangle area)

A = (50^2 * √3) / 4 + (3 * (50^2 * √3) / 4)

A = 2500 * √3 + 3750 * √3 ≈ 5884.28 ft^2

To paint 75% of the pyramid, the painter needs to paint 75% * 5884.28 ft^2 = 4413.71 ft^2

Since the painter can paint 100 ft^2 in 18 minutes, he can paint 4413.71 ft^2 in 4413.71 / 100 * 18 minutes ≈ 786.96667 minutes

Rounding to the nearest tenth, the painter will take 786.967 minutes to paint 75% of the pyramid, which is approximately 13.1 hours.

9 miles for every ½ hour and 6 miles for every 20 minutes can be considered equivalent because they represent the same speed, just measured in different units.

To see this, we can convert the units to a common unit, such as miles per hour.

First, let's convert the 6 miles in 20 minutes to miles per hour:

[tex] \frac{6}{20} \times 60[/tex]= 18 miles/hour

Next, let's compare this speed to the 9 miles per ½ hour:

[tex] \frac{9}{ \frac{1}{2} } = \frac{9}{ \frac{1}{2} } \times \frac{1}{ \frac{1}{2} } = 18[/tex]

Since both speeds are equal to 18 miles per hour, we can conclude that they are equivalent. This means that the missing values are also equivalent.

The expressions that can be used to find the area of the shaded portion of the circle are 9²·π  - (2 · 13.5π ) and 2/3 · 9²·π

Since the whole circle has a radius of 9 inches. The area of the whole circle will be 9²·π square inches (Remember: Area of circle = πr²)

Also, the area of a single section of the circle is equal to 13.5π square inches.

We can get the area of the shaded portion (blue ones) by subtracting the area of the unshaded portion (white ones) from the area of the whole circle. That is:

9²·π  - (2 * 13.5π )

Notice that we have 2 unshaded (whites)

Also, there 4 shaded portions out of the whole 6. We can write:

area of shaded portions = 4/6  ·  9²·π = 2/3 · 9²·π

Evaluating the piecewise function we will get:

f(-1) = -13

f(0) =-8

f(2)  = 10

Here we have a piecewise function and we want to evaluate it on different values of x.

When x = -1, we need to use the first part, because -1 < 0.

f(-1) = 9*-1 - 4 = -13

when x  = 0, we need to use the second part, because 0 ≥ 0.

f(0) = 9*0 - 8 = -8

When x = 2 we also use the second part:
