The best way to do this is to set up a proportion

30       20
----  = -----
0.5      x

then cross multiply and divide

20 × 0.5 = 10/30=1/3

he needs 1/3 tank of gas to drive 20 miles

I hope I've helped!

The length of a rectangular plot is 6m less than thrice its breath. Find the dimensions of the plot if its perimeter is 148m.
Elena-2011 [213]

length of a rectangle is 6 less than 3 times its width"

L = 3W-6

"perimeter of the rectangle is 148 meters"

2L + 2W = 148

L + W = 74

(3W-6) + W = 74

4W = 80

W = 20 m

L = 3W-6 = 54 m

Suppose A and B represent two different school populations where A > B and A and B must be greater than 0. Which of the follo
Ulleksa [173]
We can reject the last one: subtracting a non-zero value will result in a smaller value.

So now we have:

<span>2(A + B)
(A + B)2
A2 + B2

If all of them are mulptiplications, then they are all equivalent!

I mean by this, if what you meant is this:

</span>
<span>2*(A + B)
(A + B)*2
A*2 + B*2

If there is no sign, then the multiplication sign is implicit,


and all of these expressions say exactly the same: two of A and two of B.

What is the formula for the nth term of the given sequence 100, 20, 4, …
Naily [24]

Answer:

a_n=100 \left(\dfrac15\right)^{n-1}

Step-by-step explanation:

General equation of geometric sequence:  a_n=ar^{n-1}

Given:

  • a₁ = 100
  • a₂ = 20
  • a₃ = 4

\implies a_1=a=100

\implies a_2=100 \cdot r=20

\implies a_3=100 \cdot r^2=4

Common ratio:

r=\dfrac{a_3}{a_2}=\dfrac{4}{20}=\dfrac15

Therefore:

a_n=100 \left(\dfrac15\right)^{n-1}
