First, find the area of rectangle.

20 × 30 = 600

Next multiply the square

10 × 10 = 100

Now the curve.

[tex]\frac{10 * 10 = 100}{2}[/tex]

100/2 =50

Then Add all of it.

Answer:

40cm

Step-by-step explanation:

Centimeter means "one hundredth of a meter," so:

1 m = 100 cm

How many meters times 100 will get you how many cm:

2/5m = ? cm

2/5 (100) = ? cm

200/5 = ? cm

40 = ? cm

2/5m = 40 cm

Answer:

George Washington.

Step-by-step explanation:

The first president of the United States was George Washington. Patrick Henry and George Mason where never elected President. Thomas Jefferson was the Third President. John Adams (not a choice in your question) was the second President.

Answer:

'Percent (%)' means 'out of one hundred':

p% = p 'out of one hundred',

p% is read p 'percent',

p% = p/100 = p ÷ 100.

10% = 10/100 = 10 ÷ 100 = 0.1.

100% = 100/100 = 100 ÷ 100 = 1.

Increase the number by 10% of its value.

Percentage increase = 10% × 2,880

New value =

2,880 + Percentage increase =

2,880 + (10% × 2,880) =

2,880 + 10% × 2,880 =

(1 + 10%) × 2,880 =

(100% + 10%) × 2,880 =

110% × 2,880 =

110 ÷ 100 × 2,880 =

110 × 2,880 ÷ 100 =

316,800 ÷ 100 =

3,168

Calculate absolute change (actual difference)

Absolute change (actual difference) =

New value - 2,880 =

3,168 - 2,880 =

The slope of the line graphed in the coordinate grid will be;

⇒ m = -4/5

The equation of line in point-slope form passing through the points (x₁ , y₁) and (x₂, y₂) with slope m is defined as;

⇒ y - y₁ = m (x - x₁)

Where, m = (y₂ - y₁) / (x₂ - x₁)

Given that;

The line graphed in the coordinate grid is shown in figure.

Now,

Let two points on the graph of the line are (5, 0) and (0 , 4)

We know that;

Slope of the line passing through the points (x₁ , y₁) and (x₂, y₂) is,

⇒ m = (y₂ - y₁) / (x₂ - x₁)

Hence, Slope of the line  passing through the points (5, 0) and (0 , 4) is,

⇒ m = (y₂ - y₁) / (x₂ - x₁)

⇒ m = (4 - 0) / (0 - 5)

⇒ m = 4 / (-5)

⇒ m = -4/5

Thus, The slope of the graph = - 4/5

Answer:

x= 8.9 cm

Step-by-step explanation:

First, since we know that the radius of the circle is 5 centimeters, we know that the diameter of the circle and the hypotenuse of the triangle is 10 centimeters long. Then you use the pythagorean theorem to find out the length of side x. The equation would be: 4.5^2 + x^2= 10^2. Next, you simplify the equation by squaring the squares to get. 20.25 + x^2= 100. Finally, you would subtract 100 and 20.25 to get 79.75 and take the square root of that number to get your x value. x= [tex]\sqrt{79.75}[/tex]. When you do this equation you come out with x=8.93028554975 and then round it to the nearest tenth which is 8.9 cm.

Answer:

Yes 25% + 30% =55%

Step-by-step explanation:

yes because 25+30 =55

The final cost not be same as 55% discount.

To determine the quantity or percentage of something in terms of 100, use the percentage formula. Per cent simply means one in a hundred. Using the percentage formula, a number between 0 and 1 can be expressed. A number that is expressed as a fraction of 100 is what it is. It is mostly used to compare and determine ratios and is represented by the symbol %.

Given:

A toy store offers an additional 25% discount on board games that have already been reduced by 30%.

let the the price of toy be $100.

So, the price after 30% discount

= 100 - 100 x 0.30

= 100 - 30

= $70

and, additional 25% discount

= 70 - 70 x 0.25

= $52.5

Now, if discount is 55% then price would be

= 100 - 100 x 0.55

= $45

Hence, the case is not same.
