The figures below are similar. the area of the larger trapezoid is 121m^2. Find the area of the smaller trapezoid to the nearest
DENIUS [597]

Answer:

54 square meters

Step-by-step explanation:

Similar figures have corresponding lengths as equal ratios.

Smaller trapezoid's base is given 12 and larger trapezoids base is given 18, so the scale factor is 12k=18\\k=\frac{18}{12}\\k=1.5

<em>this means the lengths of larger is 1.5 times lengths of smaller.</em>

<em />

In terms of area, the scale factor is squared. Hence the scale factor for area is  k^2=(1.5)^2=2.25

<em>this means the area of larger is 2.25 times the area of smaller.</em>

<em />

Now, Let area of smaller trapezoid be x so we can say:  x(2.25)=121\\x=\frac{121}{2.25}\\x=53.78

<em>to nearest square meter, </em><em>x = 54 meters squared</em>

Nsider the following system of equations y=6x^2+1, y=x^2+4
sp2606 [1]

The given equations are y= 6x^2+1 and y=x^2+4

Both the equations equal y so we can make them equal

6x^2+1=x^2+4

To bring x term on one side we subtract x^2 both sides

6x^2-x^2+1=4

5x^2+1=4

To isolate x term we subtract 1 both sides

5x^2=4-1

5x^2=3

Dividing by 5 both sides

X^2=3/5

Taking root of both sides we have:

X=±√⅗

Substituting x value to find y

When x=+√⅗=0.7745

Y= 6x^2+1

Y=6(3/5)+1

Y= 18/5+1

Y=23/5 =4.6

When x= -√⅗=-0.7745

Y= 6(3/5)+1

Y=23/5=4.6

Point of intersections are ( 0.7745,4.6) and (-0.7745,4.6)
