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>

When 3/11 is written as a decimal, how many digits are in the smallest sequence of repeating digits?

It's b, 2
The reason is because 3/11=0.27 that repeats the 27 over again

A woman decides to have children until she has her first boy or until she has four children, whichever comes first. Let X = numb

rusak2 [61]

Answer:

The probability of every simple event is:

P(B)=0.5

P(GB)=0.25

P(GGB)=0.125

P(GGGB)=0.0625

P(GGGG)=0.0625

Step-by-step explanation:

For simple event B, the probability is calculate as have a boy in the first birth, so: P(B)=0.5

Then, for the event GB, the probability is calculated as the multiplication of the probability of have a girl in the first birth and have a boy in the second, so:

P(GB)=<u> 0.5 </u>* <u> 0.5 </u>=0.25

have a girl have a boy

At the same way for the event GGB, the probability is calculated as the multiplication of the probability of have a girl in the first and second birth and have a boy in the third, so:

P(GGB)=0.5*0.5*0.5=0.125

For the event GGGB, the probability is calculated as the multiplication of the probability of have a girl in the first, second and third birth and have a boy in the fourth, so:

P(GGGB)=0.5*0.5*0.5*0.5=0.0625

Finally, for the event GGGG, the probability is calculated as the multiplication of the probability of have a girl in the first, second, third and fourth birth, so:

P(GGGG)=0.5*0.5*0.5*0.5=0.0625
