Lexi is making a scale drawing of a soccer field that is 120 yards long and 80 yards wide and the field is that see strong is 30
vekshin1

Answer:

45 cm

Step-by-step explanation:

l = Length of football field is 120 yards

w = Width of football field is 80 yards

The ratio of the sides is \dfrac{l}{w}=\dfrac{120}{80}=\dfrac{3}{2}

Now the width of the field is 30 cm = w'

\dfrac{l'}{w'}=\dfrac{l}{w}\\\Rightarrow l'=\dfrac{l}{w}\times w'\\\Rightarrow l'=\dfrac{3}{2}\times 30\\\Rightarrow l'=45\ \text{cm}

The length of the field in the drawing is 45 cm.

Answer:

Your numbers are +7, -9, and 25

Step-by-step explanation:

Reverse the values of -7 and +9

Then you get +7 and -9

And also take radius squared which is 25

So, (x--7)^{2} +(y-9)^{2}  = 25

Find the sum of the following infinite geometric series, if it exists. ½ + -¼ + ⅛ + -1/16 +...
Dominik [7]
Hmm

each term is multiplied by a constant
1/2 times what=-1/4? that is -1/2
-1/4 times what=1/8? that is -1/2

so r=-1/2

does it converge or diverge?
if it converges, it has an infinite sum
if it diverges, it does not

if |r|<1 then it converges
|-1/2|<1?
1/2<1?
true
it converges and has a sum

the sum of an infinite geometric series is
S_n=\frac{a_1}{1-r} where a1 is the first term and r=common ratio

a1=1/2
r=-1/2

S_{\infty}=\frac{\frac{1}{2}}{1-(\frac{-1}{2})}
S_{\infty}=\frac{\frac{1}{2}}{1+\frac{1}{2}}
S_{\infty}=\frac{\frac{1}{2}}{\frac{3}{2}}
S_{\infty}=(\frac{1}{2})(\frac{2}{3})
S_{\infty}=\frac{2}{6}
S_{\infty}=\frac{1}{3}



the sum is \frac{1}{3}
