Answer:

20 % of n would be 12.8

Step-by-step explanation:

By first finding that 24.32 is 38% of 64. To find that you would have the fractions 38/100 = 24.32/n. From there you cross multiply the 100 times 24.32 then divide that answer by 38 to get the answer 64. you take that n=64 and find 20% of that which is 12.8.

The 20% of n is 12.8

38% of number n is given as:

[tex]38\% \times n = 24.32[/tex]

Express the percentage (38%) as decimal

[tex]0.38 \times n = 24.32[/tex]

Divide both sides of the equation by 0.38

[tex]n = 64[/tex]

Multiply both sides of the equation by 20%

[tex]20\% \times n = 20\% \times 64[/tex]

Express the percentage (20%) as decimal

[tex]20\% \times n = 0.20 \times 64[/tex]

Evaluate the product

[tex]20\% \times n = 12.8[/tex]

Hence, the 20% of n is 12.8

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: 28 shirts

Step-by-step explanation:

From the question, we are informed that Lisa sold 11 shirts for every 7 shirts Becky sold. This can be expressed in a fraction as:

Lisa = 11/(11 + 7) = 11/18

Becky = 7/(11 + 7) = 7/18

If the girls sold 72 shirts in all, the number of shirts sold by Becky will be:

= 7/18 × 72

= 7 × 4

= 28

Answer:

378

Step-by-step explanation:

We know that she bought a television for $350 and the tax rate is 8%. This means the equation will be 350+(0.08*350). We can solve that equation using benchmark fractions since that's the quicker method of doing it.

To find 8% of 350, we can do 1% of 350 = 3.5 and we just multiply 3.5*8 which is 28. So we do 350+28.

You could also do 350*.08 but that's less efficent

We can pack a maximum of 15 blankets into the 22-inch moving box.

An expression contains one or more terms with addition, subtraction, multiplication, and division.

We always combine the like terms in an expression when we simplify.

We also keep all the like terms on one side of the expression if we are dealing with two sides of an expression.

Example:

1 + 3x + 4y = 7 is an expression.com

3 + 4 is an expression.

2 x 4 + 6 x 7 – 9 is an expression.

33 + 77 – 88 is an expression.

We have,

To determine how many blankets can fit in a 22-inch moving box, we first need to calculate the volume of the box.

Since the box is 22 inches in all three dimensions (length, width, and height), its volume is:

= 22 x 22 x 22

= 10,648 cubic inches

Next, we need to divide the volume of the box by the volume of one blanket to find out how many blankets can fit inside.

= 10,648 / 704

= 15.125

We can't fit a fraction of a blanket, so we can only pack a whole number of blankets.

Therefore,

We can pack a maximum of 15 blankets into the 22-inch moving box.

Answer:

11.52 miles

Step-by-step explanation:

We know that the length of an arc L = Ф/360 × 2πR where Ф = angle subtended by arc and R = radius of circle.

Now since Ф = 10 minutes = 10 × 1 minute = 10 × (1/60)° = (1/6)° and R = radius of earth = 3960 miles

So  L = Ф/360 × 2πR

= (1/6)°/360 × 2π(3960 miles)

= 1/2160 × 7920π

= 3.67π

= 11.52 miles

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.

Answer:

The image point of P(7,-7) after a translation of 3 right and 1 down followed by a reflection over the x-axis will be:

Step-by-step explanation:

Given the point

(7, -7)

Translation of 3 right and 1 down means we need to add 3 units to the x-coordinate and subtract 1 unit from the y-coordinate

Therefore, the translation rule:

(x, y) → (x+3, y-1)

In our case, let the point P(7, -7)

P(7, -7)  → P'(7+3, -7-1) → P'(10, -8)

FOLLOWED BY A reflection over the x-axis

We know that the rule of reflection over the x-axis implies that

(x y) → (x, -y)

i.e. the x-coordinate of the point remains the same, but the y-coordinate changes its sign.

After the first transformation, we had got P'(10, -8)

so

P'(10, -8) → P''(10, -(-8)) → P''(10, 8)

Therefore, the image point of P(7,-7) after a translation of 3 right and 1 down followed by a reflection over the x-axis will be:

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
