Answer:

The area of the quadrilateral is 12 square feet. (B)

Step-by-step explanation:

To find the area of a triangle, we use the formula (L x W) / 2

The bottom triangles are both the same size, so we only need to find the area of one. The width of the triangle needs to be divided by two because we only need to know half of the big triangle on the bottom at the moment. So we have (3 x 2) / 2 = 3. We can then multiply that by two and the area of the bottom triangle is 6. To solve for the top, (3 x 4) / 2 = 6. We can then add together the top and the bottom to get B, 12 square feet.

Hope this helps!

Answer:

b = 0.4899

Step-by-step explanation:

Given;

2(2x-1)=5x²

4x - 2 = 5x²

5x² - 4x + 2 = 0

this is a quadratic equation with;

a = 5, b = -4 and c = 2

[tex]x = \frac{-b \ \ + /-\ \ \sqrt{b^2 - \ 4ac} }{2a} \\\\x = \frac{-(-4) \ \ + /-\ \ \sqrt{(-4)^2 - \ 4(5*2)} }{2(5)} \\\\x = \frac{4 \ \ + /-\ \ \sqrt{16 - \ 40} }{10} \\\\x = \frac{4 \ \ + /-\ \ \sqrt{-24} }{10}\\\\x = \frac{4 \ \ +/-\ \ (\sqrt{24)} (\sqrt{-1} ) }{10} \\\\x = \frac{4 \ \ +/-\ \ (\sqrt{24)} (i )}{10}\\\\ x = \frac{4 \ \ +/-\ \ (4.899) (i )}{10}\\\\ x = \frac{4 \ \ +\ \ (4.899) (i )}{10} \ \ or \ \ x = \frac{4 \ \ -\ \ (4.899) (i )}{10}\\\\[/tex]

in terms of a + bi, it will be simplified as;

[tex]x = \frac{4}{10} + \frac{(4.899) (i)}{10} \\\\x = 0.4 + 0.4899i[/tex]

Therefore, b = 0.4899

When the given expression is expressed in the simplest form of [tex]a+bi[/tex]  then the value of b is 0.4899.

Given-

The given expression in the problem is,

[tex]2(2x-1)=5x^2[/tex]

Simplify this,

[tex]4x-2=5x^2[/tex]

Arrange the above equation,

[tex]5x^2-4x+2=0[/tex]

Compare the above equation with general quadratic equation,

[tex]ax^2+bx+c=0[/tex]

we get,

[tex]a=5[/tex]

[tex]b=-4[/tex]

[tex]c=2[/tex]

Find the roots of the [tex]x[/tex] . The formula to find the roots of a quadratic equation can be given as,

[tex]x=\dfrac{-b\pm\sqrt{b^2-4ac} }{2a}[/tex]

[tex]x=\dfrac{-(-4)\pm\sqrt{(-4)^2-4\times5\times2} }{2\times 5}[/tex]

[tex]x=\dfrac{4\pm\sqrt{16-40} }{10}[/tex]

[tex]x=\dfrac{4\pm\sqrt{-24} }{10}[/tex]

[tex]x=\dfrac{4\pm\sqrt{-24}\sqrt{-1} }{10}[/tex]

[tex]x=\dfrac{4\pm 4.899i} {10}[/tex]

Take positive sign we get,

[tex]x=\dfrac{4+ 4.899i} {10}[/tex]

Take negative sign we get,

[tex]x=\dfrac{4-4.899i} {10}[/tex]

Compare the simplified form of  [tex]a+bi[/tex] with the root of [tex]x[/tex]

[tex]x=0.4+ 0.4899i[/tex]

here,

[tex]b=0.4899[/tex]

Hence when the given expression is expressed in the simplest form of [tex]a+bi[/tex]  then the value of b is 0.4899.

Answer:

Step-by-step explanation:

Answer:

$6.48.

Step-by-step explanation:

To calculate the total price of 4½ pounds of apples this week at the grocery store, we need to determine the price per pound after the 10% discount and then multiply it by the weight of the apples.

First, let's calculate the discounted price per pound:

Discounted price = Original price - (Original price * Discount percentage)

= $1.60 - ($1.60 * 0.10)

= $1.60 - $0.16

= $1.44

Therefore, the price per pound of apples this week, after the 10% discount, is $1.44.

Now, let's calculate the total price of 4½ pounds of apples:

Total price = Price per pound * Weight of apples

= $1.44/pound * 4.5 pounds

= $6.48

Therefore, the total price of 4½ pounds of apples this week at the grocery store, considering the 10% discount, is $6.48.

Answer:

x = 15

Step-by-step explanation:

The sum of the 3 angles in a triangle = 180°

Sum the 3 given angles and equate to 180, that is

3x - 10 + 6x + 5 + 4x - 10 = 180, simplify left side

13x - 15 = 180 ( add 15 to both sides )

13x = 195 ( divide both sides by 13 )

x = 15

the coordinates are( -2,5) and then (7,9)

Answer: 1 1/6

Step-by-step explanation:

You are adding the fractions; they do not have the same denominator so you have to find a common denominator which is six. Multiply the numerator and denominator for the first fraction by 3 and multiply the numerator and denominator for the second fraction by 2. After that you are left with a denominator of six and a numerator of 3+4. You you solve 3+4 which equals 7. You then get 7/6 can you simplify that fractions 1 1/6.

Hope this makes sense.
