Answer:
The length of the shorter base of the little trapezoid trail is 1 mi.
Step-by-step explanation:
Let the shorter base of the large trapezoid is S and the larger base of the large trapezoid is L.
Similarly, assume that the shorter base of the small trapezoid is s and the larger base of the small trapezoid is l.
Since, the trapezoids are similar, so
Now, given that S = 2 mi, L = 8 mi and l = 4 mi and we have to find s.
So, 
mi. (Answer)
Hello!
An equation has an (=). They equal something. For example, 1+1=2 is an equation.
An expression does not have an equal sign. For example, 2 or 1+3 are both expressions. They have no equal sign.
I hope this helps!
Some examples of multiples of 2/5 are 4/10, 6/15, 8/20, 10/25, 12/30, and 14/35.
Looks like you just evaluated the summand for the given value of
, whereas the question is asking you to find the value of the sum for the first
terms.
Let
. Then
is the
th partial sum.
happens to be the first term in the series, which is why that box is marked correct:
But the next partial sum is not correct:
and this is not the same notion as the second term (which indeed is 0.75) in the series.
