Answer:

10

Step-by-step explanation:

There are 10 groups of 2/5 in 4 which represent the given fraction.

A fraction is defined as a numerical representation of a part of a whole that represents a rational number.

Equivalent fractions have the same value regardless of their numerators and denominators. When simplified, 6/12 and 4/8 are both equal to 1/2, indicating that they are equivalent in nature.

To find out how many groups of 2/5 are in 4, you will need to divide 4 by 2/5.

To do this, you can follow these steps:

Rewrite the fraction 2/5 as a decimal by dividing the numerator by the denominator. This gives you 0.4.

Divide 4 by 0.4 to find the number of groups of 2/5 that are in 4.

For example, if you divide 4 by 0.4, you get:

4 / 0.4 = 10

Therefore, there are 10 groups of 2/5 in 4.

Answer:

Final cost = $2388.75

Step-by-step explanation:

Cost of stereo system = $2500

Sale = 9%

Cost of sale = 9% of 2500

Cost of sale = [tex]\frac{9}{100}*2500 = 0.09*2500[/tex]

Cost of sale = $225

Price after sale = 2500 - 225 = $2275

Sales tax = 5% of 2275

Sales tax = 0.05 * 2275 = $ 113.75

Final cost = 2275 + 113.75 = $2388.75

Answer:

The perimeter of a rectangular rug is 40 feet

Perimeter=2×(length+ width)

Let the width of the rug be x

According to the above problem,

40=2(12+x)

40/2=(12+x)

20=(12+x)

x=(20-12)

x=8

Hence, the width of the rug is 8 feet.

The width of the rectangular rug is 8 feet.

Perimeter of a straight sided figures or objects is the total length of it's boundary.

Given the perimeter of a rectangular rug and it's length.

Perimeter of rectangular rug = 40 feet

Length of the rectangular rug = 12 feet

We have to find the width of the rectangular rug.

Perimeter of a rectangular shape = 2 (l + w), where l is the length of the rectangle and w is the width of the rectangle.

Substituting these values,

Perimeter = 2 (l + w)

40 = 2 (12 + w)

40 / 2 = 12 + w

20 = 12 + w

w = 20 - 12

w = 8 feet

Hence the width of the rectangular rug is 8 feet.

Answer:

Width of the pool = 15 yards

Step-by-step explanation:

Given that:

Length of diagonal of swimming pool = 29 yards

Length of the pool = 25 yards

Let,

w be the width.

This will form a right angled triangle where the diagonal will be hypotenuse.

Using Pythagorean theorem;

[tex](25)^2+(w)^2 = (29)^2\\625+w^2=841\\w^2= 841 - 625\\w^2 = 216[/tex]

Taking square root on both sides

[tex]\sqrt{w^2}=\sqrt{216}\\w=14.70[/tex]

Rounding off to nearest whole number

w = 15 yards

Hence,

Width of the pool = 15 yards

Answer:

Well, 48 divided by 8 is 6. And 6 times 3 is 18. So I belive that there would be 18 bottles of paint.

Step-by-step explanation:

The number of bottles of paintbrushes is 18.

Any number of equal parts is represented by a fraction, which also represents a portion of a whole. A ratio shows how often one number is contained in another.

For instance, if a dish of the fruit contains eight oranges and six lemons, the ratio of oranges to lemons is eight to six. The ratio of oranges to the overall amount of fruit is 8:14, and the ratio of lemons to oranges is 6:8.

Given that the ratio of paintbrushes to bottles of paint in Ms. Nelson's supply closet is 8 to 3. If there are 48 paintbrushes.

The number of the bottles will be calculated as:-

P / B = 8 / 3

3P = 8B

3 x 48 = 8B

B = 3 x 6

B = 18

Therefore, the number of bottles of paintbrushes is 18.

Step-by-step explanation:

The function f(x)=2x−10 when the value  x=−3, 0, and 8 is,

f(0) = -10

(ii) f(8) = 6

(iii) f(−3) = −16

A function is defined as a relationship between a set of inputs, each of which has a single output. Simply put, a function is a relationship between inputs, where each input is associated with exactly one output. Each function has a domain name and a code domain or region. A function is usually denoted by f(x), where x is the input. The general representation of a function is y = f(x).

There are several different types of functions in mathematics.

The function f(x)=2x−10 when the value  x=−3, 0, and 8 is

f(0) = -10

(ii) f(8) = 6

(iii) f(−3) = −16

f is given by f(x)=2x−10

Then, we have

(i) f(0)=2(0)−10=-10

(ii) f(8)=2(8)−10=6

(iii) f(−3)=2(−3)−10=−16

The ratio of red tiles to blue tiles is 1:2. Then the number of red tiles that he uses will be 200 tiles.

A ratio is a collection of ordered integers a and b represented as a/b, with b never equaling zero. A proportionate expression is one in which two items are equal.

An artist is making a mosaic using glass tiles. He uses a total of 600 tiles. The ratio of red tiles to blue tiles is 1:2.

Let R be the red tiles and B be the blue tiles. Then the equation is given as,

R + B = 600         ...1

R/B = 1/2

B = 2R

From equations 1 and 2, we have

R + 2R = 600

3R = 600

R = 600 / 3

R = 200

The ratio of red tiles to blue tiles is 1:2. Then the number of red tiles that he uses will be 200 tiles.

The unknown values of number for each of the expression is 8, 10, 3000, 1440, and 25.

A percentage is a portion of a whole number which is expressed as a number between the range of 0 and 100 rather than as a fraction. All of a thing is 100 percent, half of it is 50 percent, and none of something is zero percent. To determine a percentage, we divide the portion of the whole through the whole of itself and multiply it by 100.

x × 150/100 = 12

x = 12 × 100/ 150

x = 1200/ 150

x = 8

x × 50/100 = 5

x = 5 × 100/ 50

x = 500/ 50

x = 10

x × 10/100 = 300

x = 300 × 100/ 10

x = 30000/ 10

x = 3000

x × 5/ 100 = 72

x = 72 × 100/ 5

x = 7200/ 5

x = 1,440

x × 80/ 100 = 20

x = 20 × 100/ 80

x = 2000/ 80

x = 25

Therefore, the values of unknown numbers are 8, 10, 3000, 1440, and 25, respectively.
