Answer: 4. 7 unit

5. 20 unit

Step-by-step explanation:

4. Since, A≡ (-7,0) and B≡ (5,0)

Thus, By the distance formula,

[tex]AB = \sqrt{(5-(-2))^2+ (0-0)^2}[/tex]

⇒ [tex]AB = \sqrt{(5+2)^2+ (0)^2}[/tex]

⇒ [tex]AB = \sqrt{(7)^2+ (0)^2}[/tex]

⇒ [tex]AB = \sqrt{49+0}[/tex]

⇒ [tex]AB = \sqrt{49}[/tex]

⇒ AB = 7 unit

5. Here EF = 9x + 14, FG = 56 and EG= 250

But, According to the given diagram,

EF + FG = EG ( because G divides the line EG )

⇒ 9x + 14 + 56 = 250

⇒ 9x + 70 = 250

⇒ 9x = 250 - 70 ( By subtracting both sides by 70)

⇒ 9x = 180

⇒ x = 20  ( by dividing both sides by 9 )

Thus, the value of x is 20.

Step-by-step explana

For a 30 second flight, the airplane will travel 4.5 miles. To cover a distance of 12.75 miles, it will take 85 seconds.

The relationship between the distance an airplane travels and the time it takes is given by the equation [tex]d=0.15t[/tex].

Here, d stands for distance in miles and t for time in seconds. The coefficient 0.15 in this equation represents the speed of the airplane in miles per second.

To find how fast the airplane is flying, we must convert this speed to a more familiar unit, such as miles per hour.

Since there are 3600 seconds in one hour, the airplane's speed in miles per hour (mph) is

[tex]0.15 miles/second \times 3600 seconds/hour = 540 mph[/tex]

Now, to determine how far the airplane will travel in 30 seconds, we substitute t with 30 in the original equation:

[tex]d = 0.15 \times 30[/tex], yielding a distance of 4.5 miles.

To calculate how long it will take the airplane to go 12.75 miles, we use the original equation but solve for t:

[tex]t = \frac{d}{0.15} t = \frac{12.75}{0.15}[/tex]

which simplifies to 85 seconds.

Answer:

2 and 3/4 lbs

Step-by-step explanation:

4 and 1/2 is equal to 9/2. If you multiply 4 by 2 and then add 1, you get 9, and put it over 2 because that is the denominator in the mixed number. Using the same method, we can find that 1 and 3/4 is equal to 7/4. However, the denominators are different, so we need to change that so they will be common. We can change 9/2 to 18/4 by multiplying both the numerator and the denominator by 2. This is technically the same as multiplying by 2/2, which is equal to 1, so the fraction will be equivalent, since anything multiplied by 1 is itself. Now we have 18/4 for the large carton and 7/4 for the small carton. Since the denominators are the same, they do not change. Just subtract the numerators to get 11, and then put it over 4 to get 11/4. In mixed number form, this is 2 and 3/4 lbs because 4 goes into 11 twice (8) and then you will have 3 left over. 8+3 = 11

The new width of the photo is 2 inches.

To find the new width of the photo, we can use the concept of proportions. Let's set up the proportion:

Original Height / Original Width = Reduced Height / New Width

Plugging in the given values, we have:

16 in / 8 in = 4 in / x

Cross multiplying, we get:

16x = 32

Dividing both sides by 16, we find:

x = 2

So the new width of the photo is 2 inches.

Final answer:

To find the quotient of 3 ÷ 2 1/3, convert the mixed number to an improper fraction (7/3), find the reciprocal (3/7), and multiply it by 3 to get 9/7, which is the answer in lowest terms.

Explanation:

The quotient of 3 ÷ 2 1/3 can be found by first converting the mixed number 2 1/3 to an improper fraction. The mixed number 2 1/3 is equal to ⅔, which when summed (2 * 3 + 1), gives us 7/3. To divide by a fraction, you multiply by its reciprocal. Thus, we have 3 × ⅓ (which is 3/7). Multiplying these we get 9/7, which cannot be further simplified. Therefore, the quotient in lowest terms is 9/7.

The quotient of 3 ÷ 2 1/3 is found by converting 2 1/3 to an improper fraction (7/3), taking the reciprocal (3/7), and multiplying it with 3. The result is the fraction 9/7, which is already in lowest terms.

To find the quotient of 3 ÷ 2 1/3, we first convert the mixed number to an improper fraction. The mixed number 2 1/3 is equivalent to 7/3 (because 2 × 3 + 1 = 7). To divide by a fraction, we multiply by its reciprocal. Therefore, we need to multiply 3 by the reciprocal of 7/3, which is 3/7.

The multiplication is straightforward: 3 × 3/7. We multiply the numerators (3 × 3) to get 9, and the denominators (1 × 7) to get 7, so we have 9/7. Since 9 and 7 have no common factors other than 1, 9/7 is already in its lowest terms. Thus, the quotient is 9/7 or 1 2/7 when expressed as a mixed number.

Answer:

Density is usually expressed as grams per cubic centimeter.

Volume = 55 * 25 * 20 = 27,500 cc

Density = Mass / Volume = 4,000 grams / 27,500 cc

= 0.1454545455 grams/cc

which is an extremely low density

Step-by-step explanation:

The density of the box is found by dividing its mass (4000 grams) by its volume (27500 cubic centimeters), resulting in a density of approximately 0.1455 grams per cubic centimeter.

To calculate the density of the box, you must find the mass per unit volume. The mass given is 4 kg, which is equivalent to 4000 grams since 1 kg = 1000 grams. To find the volume, multiply the length by the width by the height of the box:

Volume = Length × Width × Height = 55 cm × 25 cm × 20 cm = 27500 cm³

Now, divide the mass of the box by the volume to get the density:

Density = Mass / Volume = 4000 g / 27500 cm³ ≈ 0.1455 g/cm³

Therefore, the density of the box is approximately 0.1455 grams per cubic centimeter (g/cm³).

Total surface area =61.23 in ^2

Step-by-step explanation:

To find the total surface area of a cylinder, we use the formula

T . S . A . = 2 π r h + 2 π r^ 2

where r is the radius and h is the height

We know the radius is 1.5 and the height is 5

Substituting the values into the equation

T . S . A . = 2 π (1.5)(5) + 2 π (1.5) ^2

                  = 15  π +4.5  π

                   = 19.5  π

Answer:

The area of figure is 304 square unit.

Step-by-step explanation:

The figure divided into 2 equal trapezoids.The height of each is 8. The basis of each trapezoid are 14 and 24. It means the length of the parallel sides are 14 and 24.

Area of a trapezoid is

[tex]A=\frac{a+b}{2}\cdot h[/tex]

Where, a and b are length of parallel sides and h is the height of trapezoid.

Area of a trapezoid is

[tex]A_1=\frac{24+14}{2}\times 8[/tex]

[tex]A_1=19\times 8[/tex]

[tex]A_1=152[/tex]

Therefore area of a trapezoid is 152.

The area of figure is twice of area of a trapezoid.

[tex]A=2\times A_1=2\times 152=304[/tex]

Therefore the area of figure is 304 square unit.

Answer:

sum

Step-by-step explanation:

We know that, 'multiplication of two or more quantities can be expressed as the SUM of the same quantities'.

This means that 'multiplication of two or more terms is equal to adding as many copies of one of them'.

i.e. a × b = a + a + .... ( 'b' number of times ) = b + b + ... ( 'a' number of times )

Let us consider few examples,

A.  2 × 4 = 8

So, we can have that,  

2 × 4 = 2 + 2 + 2 + 2 = 8 i.e. we add the number 2 four times.

2 × 4 =  4 + 4 = 8 i.e. we add the number 4 two times.

B. 3 × 7 = 21

3 × 7 = 3 + 3 + 3 + 3 + 3 + 3 + 3 = 21 i.e. we add the number 3 seven times.

3 × 7 = 7 + 7 + 7 = 21 i.e. we add the number 7 three times.

Hence, 'The multiplication of two or more quantities may be expressed as the SUM of the same quantities'.
