12/28

multiply it by two every time

Step-by-step explanation:

Answer:

Use PEMDAS.

Parentheses: none.

Exponents: none.

MD, from left to right

6/3 = 2

2 + 32 x 4 - 2

32 x 4 = 128

2 + 128 - 2

2 + 128 = 130

130 - 2 = 128

Step-by-step explanation:

So there's 3 1's, 2 2's, 2 3's, 1 4, 2 5's, a 6, a 7, an 8, 2 0's, and no 9's.  

Multiples of 4, 8, 10

4 = 4, 8, 12, 16, 20, 24, 28, 32, 36, 40

8 = 8, 16, 24, 32, 40

10 = 10, 20, 30, 40

A common multiple = 40

Answer:

[tex]\boxed{\bold{\huge{\boxed{Area\ of\ Trapezium = 150\ cm\²}}}}[/tex]

Step-by-step explanation:

Using Pythagorean Theorem first to find EC

[tex]\sf CB^2 = EB^2+EC^2\\Where \ CB = 13 \ and \ EB = 5 \\13^2 = 5^2 + EC^2 \\169 - 25 = EC^2 \\EC^2 = 144\\Taking \ sqrt \ on \ both \ sides\\EC = 12 \ cm[/tex]

Given that:

AE = EC

AE = 12 cm

Now,

AB = AE + EB

AB = 12 + 5

AB = 17 cm

ABCD is a trapezoid / trapezium

So,

Area of Trapezium = [tex]\sf \frac{AB+DC}{2} (EC)[/tex]

Where AB = 17 , DC = 8 and EC = 12

Area of Trapezium = [tex]\sf \frac{17+8}{2} ( 12)[/tex]

Area of Trapezium = (25)(6)

Area of Trapezium = 150 cm²

The area of the canvas if, One side of the canvas is 11.4 inches long, and the shorter side is 8.3 inches is 94.62 inches².

An enclosed 2-D shape called a rectangle has four sides, four corners, and four right angles (90°). A rectangle has equal and parallel, opposite sides. Since a rectangle is a two-dimensional form, it has two dimensions: length and width. The rectangle's longer side is its length, while its shorter side is its breadth.

Given:

One side of the canvas is 11.4 inches long,

the shorter side is 8.3 inches,

Calculate the area of the canvas as shown below,

Area of the canvas = Length of the longer side × length of the shorter side,

Area of the canvas = 11.4 × 8.3

Area of the canvas = 94.62 inches².

Answer:

A quadratic equation can be written as:

a*x^2 + b*x + c = 0.

where a, b and c are real numbers.

The solutions of this equation can be found by the equation:

[tex]x = \frac{-b +- \sqrt{b^2 - 4*a*c} }{2*a}[/tex]

Where the determinant is D = b^2 - 4*a*c.

Now, if D>0

we have the square root of a positive number, which will be equal to a real number.

√D = R

then the solutions are:

[tex]x = \frac{-b +- R }{2*a}[/tex]

Where each sign of R is a different solution for the equation.

If D< 0, we have the square root of a negative number, then we have a complex component:

√D = i*R

[tex]x = \frac{-b +- C*i }{2*a}[/tex]

We have two complex solutions.

If D = 0

√0 = 0

then:

[tex]x = \frac{-b +- 0}{2*a} = \frac{-b}{2a}[/tex]

We have only one real solution (or two equal solutions, depending on how you see it)

Step-by-step explanation:

He would put it in the thousandths digit.

0.06 = 6 hundredths

0.006 =  6 thousandths

Answer:

5

Step-by-step explanation:

Let's look at the question.

Spent- He spent 45 dollars eating out.

He spent an additional 15 dollars on gas

Earned- He earned 55 dollars from mowing lawns

Earned is going to be a positive value.

Spent is going to be a negative value.

The situations don't matter in the context of the question. They are just asking how much he got charged.

The amount charged is always positive. You can never have a negative charged amount of money. That would mean the bank owed you money, which would never happen.

Let's substitute the values into an equation.

The variable C will stand for amount charged.

C = -45 + 55 - 15

Combine the negative values to get -60

Add -60 to 55.

You will get -5, which then you will have to take the absolute value of.

The absolute value will be the charge in dollars at the end of the week.

Jimmy’s change in dollars at the end of the week will be - 5 dollars.

Subtraction in mathematics means that is taking something away from a group or number of objects. When you subtract, what is left in the group becomes less.

Given that;

Jimmy spent $45 eating out, gain $55 mowing lawns and spent $15 on gas.

Now,

Let the total amount Jimmy have = x

Since, Jimmy spent $45 eating out, gain $55 mowing lawns and spent $15 on gas.

Hence, After spent $45 on eating, we get;

The left amount = x - $45

And, After spent $55 on mowing lawns, we get;

The left amount = x - 45 + 55

                         = x + 10

And, After spent $15 on gas.

The left amount = x + 10 - 15

                         = x - 5

Thus, At the end of the week, he ended up with 5 dollars less than he started, so the change is -5 dollars.

Answer:

Negative

Step-by-step explanation:

Answer:

Negative

Step-by-step explanation:

A positive divided by a negative is a negative.

Answer:

  44 inches

Step-by-step explanation:

The side length is the square root of the area:

  A = s^2

  121 in^2 = s^2

  √(121 in^2) = s = 11 in

The perimeter of a square is 4 times the side length (since all four sides are the same length).

  P = 4s = 4(11 in) = 44 in

The perimeter of the square is 44 inches.

The area of a square is 121 square inches, what is the perimeter of the square? inches

The perimeter = 44 inches

Area = 121 inches²

.°. Length of a side = √(121 inches²) = 11 inches

Now,

Perimeter of the square =

Length of a side×4

= 11 inches × 4

= 44 inches.

Step-by-step explanation:

Identify the variables (x,y) and represent them using the unknowns like this:

Let x represent the tens digit and y represent the ones digit of the number.

Relationships between the unknowns from the question:

x = 2y, and x + y = 12.

We can solve these simultaneous equations by substitution:

x + y = 2y + y = 12, 3y = 12, y = 4. So x = 8.

If a person's monthly bill from the number of  kilowatt-hours (kWh), x is modeled by the equation b = 0.15(x - 200) +20, to know the bill for a person who uses 600 kWh in a month, we will substitute x = 600 into the modeled equation as shown;

[tex]b(x) = 0.15(x - 200) +20\\\\b(600) = 0.15(600 - 200) +20\\\\b(600 )= 0.15(400) +20\\\\b(600 )= 15/100*(400) +20\\\\b(600 )= (15*4)+20\\\\b(600 )= 60+20\\\\b(600 )= 80[/tex]

Hence the bill for a person who uses 600 kWh in a month is $80
