Answer:

I think the area is 12 units.

Step-by-step explanation:

Anyone correct me if I'm wrong!

So, I started with 6 times 2 is 12 but since it's a triangle, you have to divide it by 2 . Cause if you cut a square or rectangle, it will become a triangle.

So, 6 for half of the rectangle.

Then in the middle it's a square so 2 times 2= 4.

That square is 4.

Last one would be half a square, so 2 times 2= 4. Divide it in half, you get 2.

That part is 2.

Then I think you have to add all of them, 6+4+2=12

So  I think it's 12 units??

Answer:

There are 3 shapes in the figure.

1 scalene triangle

1 equilateral triangle

1 square

the formula to find the area of a triangle is 1/2 x base x height:

Area of scalene triangle: 1/2 x 6 x 2 = 6 units^2

Area of equilateral triangle: 1/2 x 2 x 2 = 2 units ^2

Area of square: (base x height)

Area of square: 2 x 2 = 4 units^2

Then add up all the areas:

6 units^2 + 2 units^2 + 4 units^2 = 12 units^2

So the area of the entire figure is 12 square units.

Answer:

Sian would receive 20 Pounds while Abigail would receive 10 Pounds.

Step-by-step explanation:

Given that Sian is twice as old as her sister Abigail, it means that if Abigail's age is T years then Sian's age would be 2T years.

If they divide 30 pounds in the ratio of their ages, the ratio of their ages will be

T : 2T (Ratio of Abigail's gae to Sian's age)

The amount received by Abigail

= T/(T + 2T) × 30

= T/3T × 30

= 1/3 × 30

= 10 Pounds

The amount received by Sian

= 2T/(T + 2T) × 30

= 2T/3T × 30

= 2/3 × 30

= 20 Pounds

Answer:

when x=9 then y=6

Step-by-step explanation:

Given that the proportion is a direct proportion, the value of y when x = 9 is 6

From the question, we understand that y is directly proportional to y

This means that:

y = kx

Where k is the constant of proportionality

x = 6, when y = 4

So, we have:

4 = 6k

Divide by 6

k = 2/3

This means that:

y = 2/3x

When x = 9, we have:

y = 2/3 * 9

Evaluate

y = 6

Hence, the value of y when x = 9 is 6

Answer:

11/5 x^2 + 5/2 xy + 3/2 y.

Step-by-step explanation:

2x . (x+y) + 1/5 x.x + 1/2 y . (x + 3)

= 2x^2 + 2xy + 1/5 x^2 + 1/2xy + 3/2 y

= 11/5 x^2 + 5/2 xy + 3/2 y.

Answer:

(7, 32) and (2, 12)

Step-by-step explanation:

y = 4x + 4

y = x² - 5x + 18

4x + 4 = x² - 5x + 18

x² - 9x + 14 = 0

14 = (-7)(-2)

-9 = -7 + (-2)

(x - 7)(x - 2)=0

x= 7, x = 2

For x = 7

y = 4x + 4  = 4*7 + 4 = 32

(7, 32)

For x = 2

y = 4x + 4 = 4*2 + 4 = 12

(2, 12)

Check:

y = x² - 5x + 18

(7, 32)

32 = 7² - 5*7 + 18

32= 32 true

(2, 12)

12 = 2² - 5*2 + 18

12 = 12 true

Answer:

Step-by-step explanation:

Total number of staffs = 6400 employees

If after the holiday they will decrease their staff bye 30%, the amount of staffs decreased = 30% of 6400

= 30/100 * 6400

= 1920employees.

Amount of staffs that they will have after the holiday = Total staffs - decrement

Amount of staffs that they will have after the holiday = 6400 - 1920

= 4480employees

Answer:

1 5/12 lb

Step-by-step explanation:

This is a subtraction problem.

He started with 4 2/3 lb and used 3 1/4 lb, so you need to subtract 3 1/4 lb from 4 2/3 lb.

Notice that the fractions do not have the same denominator, so we need a common denominator and equivalent fractions.

We start with the

subtraction below

       4 2/3

  -    3 1/4

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

The least common denominator of 3 and 4 is 12. 12/3 = 4, and 12/4 = 3, so we get equivalent fractions with the common denominator 12.

We use the LCD to get

the subtraction below

       4 8/12

  -    3 3/12

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

Now we subtract the whole numbers and the fractions.

       4 8/12

  -    3 3/12

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

       1 5/12

Answer:

f(x) > 0 over the interval [tex](-\infty,-4)[/tex]

Step-by-step explanation:

If  f(x)  is a continuous function,  and that all the critical points of behavior change are described by the given information, then we can say that the function crossed the x axis to reach a minimum value of -12 at the point x=-2.5, then as x increases it ascends to a maximum value of -3 for x = 0 (which is also its y-axis crossing) and therefore probably a local maximum.

Then the function was above the x axis (larger than zero) from [tex]- \infty[/tex], until it crossed the x axis (becoming then negative) at the point x = -4. So the function was positive (larger than zero) in such interval.

There is no such type of unique assertion regarding the positive or negative value of the function when one extends the interval from [tex]- \infty[/tex] to -3, since between the  values -4 and -3 the function adopts negative values.

[tex]a_1[/tex] is the first term of the sequence, which is [tex]\boxed{-4}.[/tex]

[tex]r[/tex] is the common ratio of the sequence, the number that you multiply one term by to generate the next term. Here, we see that multiplying by -2 will generate the next term, so [tex]\boxed{r=-2}.[/tex]

We use the formula [tex]S_n=\frac{a_1(r^n-1)}{r-1}[/tex] to find the sum of the first 6 terms - just plug in our values for [tex]a_1[/tex] and [tex]r:[/tex]

[tex]S_6=\frac{-4((-2)^6-1)}{-3}=\frac{-4(63)}{-3}=\boxed{84}.[/tex]

Answer:

Step-by-step explanation:

Given y=2x(Let's call this eqn1) and y=x+4(eqn2)

We can substitute eqn1 in eqn2 to get

2x=x+4

2x-x=4

x=4

Substitute the value x in eqn1

y=2x

y=2(4)

y=8

Answer:

C. (4, 8)

Step-by-step explanation:

→Plug in y = 2x into y = x + 4, like so:

y = x + 4

2x = x + 4

→Subtract x from both sides:

x = 4

→Now plug in 4 for x into one of the equations (doesn't matter which one):

y = 2x

y = 2(4)

y = 8

Answer:

15.59

Step-by-step explanation:

The answer is 15.59 because to find the area of an equilateral triangle, you need to multiply the height by the length. In this scenario, the length is 6, and we need to find the height. Since we know that all of the sides of the equilateral triangle are 6, we can put a line dividing the equilateral triangle exactly in half as our height. This will form 2 triangles, and each of them will have a length of 3, and a slant height of 6. They would also be right triangles. Now, with this information you can do pythageroum thereom to find the height:: 3^2 + h^2 = 6^2. So, h = √27. Now, to find the area of a triangle, you must multiply the length by the height and then divide by 2. So (6 • √27)/2 is equal to 15.5884572681, which rounded is equivalent to 15.59. So the answer is 15.59.
