The amount of degrees in a polygon: 360

In a pentagon: 360 / 5 = 72

9x - 18 = 72 Add 18 to both sides

9x = 90 Divide by 9

x = 10

A survey of 800 college seniors resulted in the following crosstabulation regarding their undergraduate major and whether or not

k0ka [10]

Using the percentage concept, it is found that of those students who are majoring in business, the percentage plans to go to graduate school is given by:

c. 28.8.

<h3>What is a percentage?</h3>

The percentage of an amount a over a total amount b is given by a multiplied by 100% and divided by b, that is:

$P = \frac{a}{b} \times 100\%$

In this problem, there are 252 students majoring is business, and of those, 70 plan to go to graduate school, hence the percentage is given by:

$P = \frac{70}{252} \times 100\% = 28.8\%$

Hence option C is correct.

Answer:

x = 5

Step-by-step explanation:

Locate - 3 on the y- axis, move across to the right to where the graph is.

Go vertically up from this point to meet the x- axis at point x = 5

Thus

f(x) = - 3 ⇒ x = 5

Answer:

424 yards²

Step-by-step explanation:

Diameter 22, radius 11

Outer circle: radius = 11+5 = 16

Area of the path:

Pi× (16²-11²)

= 135pi yards²

Or, 424 yards² (3 sf)

Murrr4er [49]

Answer:

2009

Step-by-step explanation:

The question can be interpreted as:

$f(x) = -1.330x^2 + 5.149x + 5.517$

Required

Determine x when f(x) = 10.5

Substitute 10.5 for f(x) in $f(x) = -1.330x^2 + 5.149x + 5.517$

$10.5 = -1.330x^2 + 5.149x + 5.517$

Collect Like Terms

$-1.330x^2 + 5.149x + 5.517-10.5=0$

$-1.330x^2 + 5.149x -4.983=0$

Using quadratic formula

$x = \frac{-b \± \sqrt{b^2 - 4ac}}{2a}$

Where

$a = -1.330$

$b = 5.149$

$c = -4.983$

$x = \frac{-5.149 \± \sqrt{5.149^2 - 4*-1.330*-4.983}}{2*-1.330}$

$x = \frac{-5.149 \± \sqrt{0.002641}}{-2.660}$

$x = \frac{-5.149 \± 0.0514}{-2.660}$

Split:

$x = \frac{-5.149 + 0.0514}{-2.660}\ or\ x = \frac{-5.149 - 0.0514}{-2.660}$

$x = \frac{-5.0976}{-2.660}\ or\ x = \frac{-5.2004}{-2.660}$

$x = 1.92\ or\ x = 1.96$

Both values of x approximates to 2.

So:

$x = 2$

2 years after 2007 is 2009.

Hence, the funding is about $10.5 billion in 2009
