Answer:

$16.80

Step-by-step explanation:

Given the following question:

40% of 28

To find the new price of the item we use the formula to calculate percentages then we take that answer and subtract it from the original price.

[tex]\frac{p\times n}{100}[/tex]
[tex]\frac{40\times28}{100}[/tex]
[tex]40\times28=1120[/tex]
[tex]1120\div100=11.2[/tex]
[tex]=11.20[/tex]

Subtract from original cost:

[tex]28[/tex]
[tex]28-11.20=16.8[/tex]
[tex]=16.80[/tex]

New price of the item is "$16.80."

Hope this helps.

Answer:

  (c)  135°

Step-by-step explanation:

Angles 5 and 8 form a linear pair, which means they are supplementary: their measures total 180°.

  ∠8 = 180° -∠5 = 180° -45°

  ∠8 = 135°

Answer:

$2.10

Step-by-step explanation:

Since 7 minutes is half of 14 minutes, the price of the 14 minutes phone call must be two times the cost of the 7 minute phone call.

[tex]\frac{14}{7}[/tex]= 2

$1.05 should be multiplied with 2 to find the price of the 14 minute phone call.

$1.05 × 2 = $2.10

The dual effect of low income and victimization is called

This refers to the marginally low returns which a person gets as a result of work done over a particular time period.

With this in mind, we can see that when a person earns low income, often he is victimized because he earns so little and as a result of this, such a person can become depressed and this aftereffect is known as compounding vulnerability.

Answer:

A. 67.12 cm²

Step-by-step explanation:

The rectangle is 3 cm by 6 cm.

area of rectangle = 3 cm × 6 cm = 18 cm²

The triangle has a 6 cm base and an 8 cm height.

area triangle = 6 cm × 8 cm / 2 = 24 cm²

The semicircle has a diameter of 8 cm and a radius of 4 cm.

area semicircle = (1/2)(3.14)(4 cm)² = 25.12 cm²

Add the three areas to find the total area.

18 cm² + 24 cm² + 25.12 cm² = 67.12 cm²

Answer: A. 67.12 cm²

Answer: there are 9 dims

Step-by-step explanation:

Answer:

Step-by-step explanation:

f(x) = (x-1)(x-3)(x+5) + 72

if f(x) = 72, then

(x-1)(x-3)(x+5)=0

do

x-1=0, x=1

x-3=0, x=3,

x+5=0, x=-5

Answer:

x = 1, 3, -5

The values of x are 1, 3, and 5. Then the sum of the values of the x will be 1 + 3 + 5 = 9

The function is an expression, rule, or law that defines the relationship between one variable to another variable. Functions are ubiquitous in mathematics and are essential for formulating physical relationships.

The function is given as below.

f(x) = (x – 1)(x – 3)(x + 5) + 72 ...1

And

f(x) = 72 ...2

From equations 1 and 2, we have

(x – 1)(x – 3)(x + 5) = 0

The value of x will be

x = 1, 3, and 5

The sum of the values of the x will be

⇒ 1 + 3 + 5 = 9

Answer: x = 77 degrees, y = 77 degrees, z = 103 degrees

Step-by-step explanation:

Since y and 103 are essentially same side interior angles, they must add up to 180. Therefore, y = 180-103 = 77 degrees.

Opposite angles of a paralellogram are equal.

Therefore, x = y = 77 degrees and z = 103 degrees

The measure of the three missing angles in the parallelogram are,

⇒ ∠x = 78

⇒ ∠ y = 78°

⇒ ∠z = 103°

A rectangle is a two dimension figure with 4 sides, 4 corners and 4 right angles. The opposite sides of the rectangle are equal and parallel to each other.

Given that;

The parallelogram shown in figure.

We know that;

By Opposite Angles Theorem,

In parallelogram, The two opposite angles of a parallelogram are equal to each other.

Hence, We get;

⇒ ∠z = 103°

⇒ ∠x = ∠y

And, The sum of all angles in a parallelogram is 360°.

Hence, We get;

⇒ ∠x + ∠y + ∠z + 103° = 360

⇒ ∠x + ∠x + 103 + 103 = 360

⇒ 2∠x + 206 = 360

⇒ 2∠x = 360 - 206

⇒ 2 ∠x = 156

⇒ ∠x = 78

And, ∠ y = 78°

Answer:

9

Step-by-step explanation:

Option C is correct, the maximum area of the rectangle is 9 square units.

The area of Rectangle is length times of width.

The equation f(x) = –(x – 3)² + 9 can be used to represent the area of a rectangle with a perimeter of 12 units.

We can determine the maximum area of the rectangle by finding the maximum value of the function.

To find the maximum, we take the derivative of the function and set it equal to zero, then solve for x.

f'(x) = -2(x - 3) = 0

x = 3

When x = 3, the maximum area of the rectangle is 9 square units.

Hence,  the maximum area of the rectangle is 9 square units, Option C is correct.
