D) Pentagon, it is the only one which doesn't have 4 sides/corners, but 5 instead, and therefore also has no parallel sides

Answer:

The polygon that does NOT belong with the other three is a pentagon.

Step-by-step explanation:

A polygon is a 2 D shape formed with straight lines. Like - triangles, quadrilaterals, pentagons, hexagons etc.

Here in the given choices, parallelogram , rectangle and rhombus all are four sided polygons and has parallel sides.

Only pentagon has 5 sides with no parallel sides.

Hence, the polygon that does NOT belong with the other three is a pentagon.

A vehicle uses 1 1/8 gallons of gasoline to travel 13 1/2 miles. At this rate, how many miles can the vehicle travel per gallon

valentina_108 [34]

Answer:

12 miles

Step-by-step explanation:

The problem above is related to the topic on "Equivalent Ratios." The missing term above is <em>"the number of miles that the vehicle can travel per gallon of gasoline."</em> In order to find this term, you have to use the "cross products."

Let n be the missing term.

$1\frac{1}{8} gallons$ / $13\frac{1}{2} miles$ = $\frac{1 gallon}{n}$

$\frac{9}{8} gallons$ / $\frac{27}{2} miles$ = $\frac{1 gallon}{n}$

$\frac{9}{8}$ x n = $\frac{27}{2}$ x 1 gallon

n = $\frac{27}{2}$ ÷ $\frac{9}{8}$

n = $\frac{27}{2}$ x $\frac{8}{9}$

n = 12 miles

Therefore, the vehicle can travel 12 miles per gallon of gasoline.

Let f(x)=−12(x+2)2+5 . What is the average rate of change for the quadratic function from x=−3 to x = 1?

aev [14]

Answer:

Average rate of change = -6

Step-by-step explanation:

The average rate of change over the interval (a,b) is given by;

[ f(b) - f(a)] / (b-a)........................where interval is (a,b)

(a,b) interval =(-3,1)

Where;

f(x)= -12 (x+2)² +5

$f(a)=f(-3)=-12(-3+2)^2+5\\f(a)=f(-3)=-12(-1)^2+5\\f(a)=f(-3)=-12(1)+5\\=-12+5=-7\\\\\\f(b)=f(1)=-12(1+2)+5\\f(b)=f(1)=-12(3)+5\\=-36+5=-31\\\\f(b)-f(a)=-31--7=-24\\\\b-a=1--3=4\\\\f(b)-f(a)/b-a=\frac{-24}{4} =-6$

Step-by-step explanation:

solving this we need 2 different equations

one for he total bills and one for the total money

x+y=30

that is total bills

5x+10y=240

combining both equations we can use elimination method and get
