Answer: 2.31

Step-by-step explanation: 0.462 divided by 0.2 is 2.31. I knew it was going to be over 2 because 0.2 times 2 is 0.4.

Answer:

2.31

Step-by-step explanation:

0.2 goes into 0. 2 times.   First part of answer: 2

0.2 goes into  0.06 3 times.   second of answer: 3

0.2 goes into 0.002  one time. Third part of answer: 1

Answer:  16.205 cm²

It takes some time, but it's not impossible!

Step-by-step explanation:

Find the area of the triangle, then subtract the area of the three sectors.

 The three sectors are each 60° so they add to 180° which is equivalent to half the area of one circle.  

The area of the triangle is one half base times height. To find the height of the triangle, use the Pythagorean Theorem to get the length of the perpendicular bisector.

a² + b² = c² .  

C is the side length, 20cm. (the length of two radii) B is half the side length 10cm. A is the "altitude" or height we need to find.  

a² + 10² = 20²

a² + 100 = 400 .  a² = 400-100

a² = 300

a = √300   a ≈ 17.3205

Area of triangle: A= bh/2

A = (20 × 173.205)/2

Triangle Total Area ≈ 173.205

To the area of the circle, use the equation A = πr²  

A = 3.14 × 10²

A = 3.14 × 100  

Circle Total Area =  314 cm².  

You could take 1/6 of that, and then multiply by 3,  or just take half

Area of sectors=  157 cm²

Triangle Area - Sectors Area = Blue shape Area

173.205 - 157 ≈ 16.205 cm²

Step-by-step explanation:

The question is incomplete, here is the complete one

A jacket was on sale for 20% off its original price of $60. Now, it is on sale for an additional 10% off its previous sale price. Determine whether each statement is true or false. The jacket is now 40% off its original price. True or false The jacket now costs $48.00. True or false The jacket is now 72% of its original price. True or false The jacket now costs $43.20. True or false

Step one:

given

original price= $60

discount =20% of 60

discount = 20/100*60

discount = 0.2*60

discount = $12

selling price= 60-12= $48

Added price= 10% off $48

Added price= 10/100 *48  

Added price= 0.1 *48

Added price= $4.8

new price= 4.8-48=$43.2

the new price of the jacket is $43.2

1. The jacket is now 40% off its original price

40/100*60=$24-----False

2. The jacket now costs $48.00-----False

3.  The jacket is now 72% of its original price= 72/100*60=$43.2----True

4. The jacket now costs $43.20------True

Step-by-step explanation:

he is correct because the transformation is a translation and under the translation the image and preimage are congruent.

the measure of the sides are preserved, and the peasure of the angles are preserved so if all the corsponding sides and angles are congruent the hexagons are congruent too

Answer:

(x, y) -----> ( - x , y - 10 )

Step-by-step explanation:

Titus is not correct.

There are two transformations will correctly prove FEDCBA ≅ F'E'D'C'B'A'

First transformation is Reflection over y-axis , then translation 10 units down.

The final formula is ( - x , y - 10 )

Answer:

y+10 = -5(x-3)

Explaination:

Finding the slope intercept form provides you with the line your looking for

here you want to isolate y

y = -5(x-3)-10

and then ditrubute the -5 into the parenthesis

y = -5+15-10

Combine like terms

y = -5x +5

and by looking at this in terms on y=mx+b

the line will intercept the y-axis at (5,0) like the line above shows

Answer:

y = 50x+25

f(x) = 50x+25

Step-by-step explanation:

Using the slope intercept form of the equation, y = mx+b

where x is the amount per day and b is the flat fee

2 days

125 = 2x+b

5 days

275 = 5x+b  

Subtract

275 = 4x+b  

125 = 2x+b

---------------------

150 = 3x

Divide by 3

150/3 = 3x/3

50 =x

The cost per day is 50 dollars

y = 50x +b

Using the data for 2 days

125 = 50*2 +b

125 = 100 +b

125-100 = b

b = 25

The equation is y = 50x+25

f(x) = 50x+25

To graph, The x axis is number of days and the y axis is total cost

The number of days starts with 0, which is the y intercept

Let x = 0, y =25

Using the slope, we go 50 up and 1 to the right ( 50 dollars per day)

The next point plotted ins ( 1,50)

Draw a straight line

Answer:

y = 50x+25

f(x) = 50x+25

Answer:

C

Step-by-step explanation:

To simplify the equation, all you need to do is add 12 to both sides to cancel out the -12.

The equations that are equivalent to the equation 3x - 12 = 24 are

3x = 36

x - 4 = 8

15x - 60 = 120

Options A, C, and D are correct.

An equation is a mathematical statement that is made up of two expressions connected by an equal sign.

Example: x + 2 = 7 is an equation.

We have,

3x - 12 = 24 ____(1)

From (1)

Adding 12 on both sides.

3x = 24 + 12

3x = 36 ____(2)

From (1)

Dividing 3 into both sides.

x - 4 = 8 ____(3)

From (1)

Multiplying 5 into both sides.

5 (3x - 12) = 5 x 24

15x - 60 = 120 ____(4)

From (2), (3), and (4) we see that,

3x = 36

x - 4 = 8

15x - 60 = 120

Thus,

The equations that are equivalent to the equation 3x - 12 = 24 are

3x = 36

x - 4 = 8

15x - 60 = 120

Options A, C, and D are correct.

The linear equation for this situation is,

⇒ y = 75x

And, There are 75 apple pick in one hour.

What is linear expression?

A linear expression is an algebraic statement where each term is either a constant or a variable raised to the first power.

Given that;

The graph shows how many apples Erin can pick if she ,maintain a constant rate.

Now,

Let two points on the graph are (0, 0) and (1, 75).

So, Slope of the graph (m) = (75 - 0) / (1 - 0)

                                         = 75

Thus, The linear equation is;

⇒ y - y₁ = m (x - x₁)

⇒ y - 0 = 75 (x - 0)

⇒ y = 75x

Where, y is number of apples and x is number of hour.

Thus, Number of apple pick in one hour is;

⇒ y = 75 x 1

⇒ y = 75

So, There are 75 apple pick in one hour.

Therefore, The linear equation for this situation is,

⇒ y = 75x

And, There are 75 apple pick in one hour.
