Answer:

Find the area of the outer trapezoid and then subtract the area of the inner trapezoid. The area of the outer trapezoid is 24 square units and the area of the inner trapezoid is 9 square units So the area of the shaded region is 15 square units.

Solution:

[tex]A_{outer} = (a+b)\frac{h}{2} = (2 + 6)\frac{6}{2} = 8 * 3 = 24[/tex]

[tex]A_{inner} = (a + b)\frac{h}{2} = (2 + 4)\frac{3}{2} = 6 * 1.5 = 9[/tex]

[tex]A_{shaded} = A_{outer} - A_{inner} = 24 - 9 = 15[/tex]

The other guy has mislead other people. If i turned my thing in, I would have gotten a 90% instead of 100%.

It is A.

38 degrees.

The measure of x is (a) 38 degrees

The given parameters are:

[tex]mAB = 27^o[/tex]

[tex]mCD = 49^o[/tex]

The measure of x, is the average of angles AB and CD.

So, we have:

[tex]x = \frac{mAB + mCD}{2}[/tex]

Substitute known values of AB and CD in the above equation.

So, we have:

[tex]x = \frac{27^o + 49^o}{2}[/tex]

Add 27and 49

[tex]x = \frac{76^o}{2}[/tex]

Divide 76 by 2

[tex]x = 38^o[/tex]

Hence, the measure of x is (a) 38 degrees

Answer:

Step-by-step explanation:

There are 8 possible angles that you could have been asked about, but 4 of them equal 1 value and the other 4 equal the second value.

<1 and 115 degrees are corresponding angles. They are equal. Corresponding angles occupy the same relative position.

<1 = 115 degrees.

<2 is the supplement of 115 degrees.

<2 = 180 - 115

<2 =65

Answer:

x = 16

Step-by-step explanation:

Given a tangent and a secant from an external point to a circle, then

The product of the external part and the whole of the secant is equal to the square of the tangent, that is

9(9 + x) = 15²

9(9 + x) = 225 ( divide both sides by 9 )

9 + x = 25 ( subtract 9 from both sides )

x = 16

Answer:

20(x+15)(x+10)

Step-by-step explanation:

Hi there!

As your question states, we need to fully factor the polynomial: 20x²+500x+3000

These are pretty big numbers; let's pull out the GCF, as that will make it easier to factor

the GCF is 20

so factoring 20 out of the polynomial will get:

20(x²+25x+150)

As you can see, the polynomial inside the parenthesis is a lot easier to factor than the original with really big numbers.

Now use FOIL to factor x²+25x+150 into 2 binomials

25 is the sum of the last terms

150 is the product of the last terms

think: which two numbers add up to 25 but multiply to get 150?

those two numbers are 15 and 10

x²+25x+150 factored is (x+15)(x+10)

but remember we have the 20 in front of x²+25x+150  (or now, (x+15)(x+10))

therefore the fully factored binomial is 20(x+15)(x+10)

Hope this helps! :)

Answer:

Cost of shirt

c = $5.50x

$115.5

20 t - shirts

Step-by-step explanation:

The dependent variable here is Cost of shirt

T - shirt cost , c equation of any number of customers :

The cost per shirt = $5.50

Let the number of shirts purchased = x

Hence,

c = $5.50x

The cost 21 shirts

x = 21

c = $5.50 * 21 = $115. 5

With c = $110

number of shirts, n equals

110 = 5.50x

110/ 5.5 = x

20

= 20 at shirts

Answer:

11.55 years

Step-by-step explanation:

Given data

Principal= $3000

Rate= 6%

Final Amount= $6000

expression for the time is given as

t = ln(A/P) / r

Substitute

t= ln(6000/3000)/0.06

t= ln(2)/0.06

t= 0.693/0.06

t= 11.55 years

Hence the time is 11.55 years

The simplified form of the given expression.

Solution:

We have,

[tex]\dfrac{7^{x+2}-9\cdot 7^x}{-20\times 7^x}[/tex]

It can be written as

[tex]\dfrac{7^{x+2}-9\cdot 7^x}{-20\times 7^x}=\dfrac{7^{x}\cdot 7^{2}-9\cdot 7^x}{-20\times 7^x}[/tex]

[tex]\dfrac{7^{x+2}-9\cdot 7^x}{-20\times 7^x}=\dfrac{7^{x}(49-9)}{-20\times 7^x}[/tex]

Cancel out the common factors.

[tex]\dfrac{7^{x+2}-9\cdot 7^x}{-20\times 7^x}=\dfrac{40}{-20}[/tex]

[tex]\dfrac{7^{x+2}-9\cdot 7^x}{-20\times 7^x}=-2[/tex]
