8. The trapezoids are similar. The area of the smaller trapezoid is 131 m2. Find the area of the larger trapezoid to the nearest

kolbaska11 [484]

Answer:

$3,726\ m^{2}$

Step-by-step explanation:

step 1

Find the scale factor

we know that

If two figures are similar, then the ratio of its corresponding sides is equal to the scale factor

Let

z----> the scale factor

x----> corresponding side of the larger trapezoid

y----> corresponding side of the smaller trapezoid

$z=\frac{x}{y}$

we have

$x=64\ m$

$y=12\ m$

substitute

$z=\frac{64}{12}$

step 2

Find the area of the larger trapezoid

we know that

If two figures are similar, then the ratio of its areas is equal to the scale factor squared

Let

z----> the scale factor

x----> area of the larger trapezoid

y----> area of the smaller trapezoid

$z^{2}=\frac{x}{y}$

we have

$z=\frac{64}{12}$

$y=131\ m^{2}$

substitute

$(\frac{64}{12})^{2}=\frac{x}{131}$

$x=(\frac{4,096}{144})(131)$

$x=3,726\ m^{2}$

If Kayla has a red ribbon with length 25 9 m and piece of 5 7 m is cut from it and gave to Sania . Find how much long ribbon left with her?

Kayla has a ribbon of length = 25 9 m.
Part of ribbon give to Sania = 5 7 m.
So, the length of the ribbon left =25 9 m - 5 7 m = 175 63 = 130 63 m
So , the ribbon left with Kayla is 2.06 m .

Which one is the answer??

BARSIC [14]

Answer:

Step-by-step explanation:

City X = 3 * 10^5 Given

City Y = 6 * 10^6

Times larger

6 * 10^6

3 * 10^5

Do the division

6*10^6/3^10^5 = 60 * 10^5/(3 * 10^5) Note 10^5 will cancel

60/3 = 20 City y is 20 times City x
