Answer:122.3 days

Step-by-step explanation:

1300÷159,000= 122.3

Answer:

Step-by-step explanation:

From the diagram in the image attached:

Base of triangle = [tex]20cm - ( 4 + 3)cm[/tex]

Base of triangle = [tex]20 - 7 = 13cm[/tex]

Height = 9cm

Area of triangle = (0.5) × base × height

Area of triangle = [tex]0.5 \times 13 \times 9 = 58.5cm^2[/tex]

Area of rectangle = Length × width

Area of rectangle = [tex]20 \times 9 = 180[/tex]

Shaded area = area of rectangle - area of triangle

Shaded area = [tex]180cm^2 - 58.5cm^2[/tex]

Shaded area = [tex]121.5cm^2[/tex]

Answer:

x = 24

Step-by-step explanation:

27 x 4 = 108

18 x 3 = 54

9 x 2 = 18

108 - 54 + 18 = 3x

72 = 3x

72/3 = x

24 = x

Answer:

the answer is A

Answer:

36 m^2

Step-by-step explanation:

the formula for the area of a triangle is 1/2•b•h

so you’re going to do 1/2 times 12 times 6 to get the area of 36 m^2

Step-by-step explanation:

slope = (y2 - y1)/(x2 - x1)

-4/3 = (6 - y)/[4-(-2)]

-4/3 = (6-y)/6

(-4/3)×6 = 6-y

-8 = 6-y

y = 6 + 8

= 14

Answer: y=14

Answer:

1.35

Step-by-step explanation:

To answer this problem, use order of operations (PEMDAS)

5 x 2.34 = 11.7

11.7 - 9= 2.7

2.7 / 2 = 1.35

Hope this helps.

Answer: 1.35

Step-by-step explanation:

(5 * 2.34) = 11.7

11.7 - 9 = 2.7

2.7/2 = 1.35

Answer:not sure either

Step-by-step explanation:

1) 4x + 9 = 2x - 6

Subtract 9 from both sides

4x = 2x - 15

Subtract 2x from both sides

2x = -15

Divide both sides by 2:

x = -15/2 or -7.5

2) 2(x - 5) = 5x + 23

Expand the brackets:

2x - 10 = 5x + 23

Subtract 23 from both sides

2x - 33 = 5x

Subtract 2x from both sides

3x = -33

Divide both sides by 3

x = -11

3) 7x + 3 = 2x + 13

Minus 3 from both sides

7x = 2x + 10

Subtract 2x from both sides

5x = 10

Divide both sides by 5

x = 2

Answer:

If you're scaling up from a smaller figure to a larger one, plug the lengths into the equation scale factor = larger length over smaller length. If you're scaling down from a larger figure to a smaller one, use the equation scale factor = smaller length over larger length.

Step-by-step explanation:

Answer:

448 ft^2

Step-by-step explanation:

The area of the walls is the perimeter of the room multiplied by the height.

P = 2(L + W)

P = 2(13 ft + 15 ft)

P = 2(28 ft)

P = 56 ft

A = perimeter * height

A = 56 ft * 8 ft

A = 448 ft^2

Answer:

31.1

Step-by-step explanation:

28'' = 7'' per side

Square diagonal = 7 squareroot 2

7 squareroot 2 = Diameter

[tex]\frac{7\sqrt{2} }{2}[/tex] = radius

Area =2 pi r

Answer: Conditional statement

Step-by-step explanation:

Hypotheses followed by a conclusion is called an If-then statement or a conditional statement. This is noted as. p→q. This is read - if p then q. A conditional statement is false if hypothesis is true and the conclusion is false.

Answer:

Part 1: The perimeter of total grazing area is 100 feet.

Part 2: The cost of fencing the entire grazing area is $759.

Part 3: The total cost to build a fence around the entire land of the large scaled farm is $ 45540.

A= perimeter X apothem /2

A=500

apothem = 10

500 = (P * 10)/2

P =100

B. 100*7.95 = $795

C.

60*100= 6,000

6,000 * $7.95=

Answer:

y = 4

Step-by-step explanation:

We have,

5x + 3y = 12 ....(1)

and

-5x + 4y = 16 ....(2)

Adding equation (1) and (2),

0 + 7y = 28

or

7y = 28

Dividing both sides by 7,

y = 4

So, the value of y = 4.

Answer:

The expected value of the game is  $131

Step-by-step explanation:

54 Cards in a deck including Jokers

52 Cards in a deck not including Jokers

13 Hearts

13 Clubs

13 Spades

13 Diamonds

13 Face Cards

13 / 52  = 25% Chance Of Pulling A Heart

30 / 52 = 57% Chance Of Pulling A Face Card Not A Heart

9 / 52 = 17% Chance of Loosing $6

$130 = Pick A Heart

$81 = Face Card Not a Heart

$130+$81 = $211

30 x 6 = $180

The expected value of the game is  $131

Answer:

The least common multiple, but you can use the greatest common factor, but at the end you have to simplify for it to be correct. 1 3/30

Step-by-step explanation: 4/15+5/6

Change 15 into a 30 by multiplying 2 to both sides.

Change 6 into a 30 by multiplying 5 to both sides.

so the new fractions are 8/30+25/30=33/30

The final fraction is 1 3/30.

Hope it helps

Good luck on your assignment

The area of the circle is 9π m².

What is the area of the circle?

The area of a circle is the area inside the circle. Hence, the area of the circle = π × R².

Given, the diameter of the circle is(D) = 6 m.

Radius of the circle(R) = D/2 = 6/2 m = 3 m.

Therefore, the area of the circle = π × R² = π × 3² m² = 9π m².

Answer:

The probability that a coin flip is a head or a tail is 0.5. The probability that a coin flip is either a head or a tail is 1. The probability that a three-coin-flip is two heads and a head or a tail is 0.25.

Step-by-step explanation:

Answer: 2.5%

Step-by-step explanation:

Let's use the rule of 3 here.

If the total price is $275,000 or 100% of the sale, then $6,875 is X% of the total sale.

Let's put money on one side and percentages on the other.

[tex]\frac{275000}{6875}=\frac{100}{x}[/tex]

Solve for x;

[tex]x=\frac{6875*100}{275000}[/tex]

[tex]x=2.5[/tex]

The Percent commission Miguel earn is 2.5%.

Given:

Miguel sells a house = $275,000

His commission for the sale =$6,875.

Step 1:

Let's use the rule of 3 here.

If the total price is $275,000 or 100% of the sale,

then $6,875 is X% of the total sale.

Step 2:

Let's put money on one side and percentages on the other

=275000/6875

= 100/x

Solve for x;

x = 6875×100/275000

x = 2.5

Therefore, Percent commission did Miguel earn is 2.5%.

Step-by-step explanation:

Firstly note that the graph is shifted up 2 units, as it starts at positive 2, when it should start at 0.

That only leaves choices 1 and 2

However, since we know its flipped, we can easily rule out number 2, as number 2 wouldn't be a real number(sqrt of negatives)

That leaves answer choice 1

The correct option is y = -[tex]\sqrt{x}[/tex] +2

A transformation is a process that manipulates a polygon or other two-dimensional object on a plane or coordinate system.
