Triangle STU is similar to triangle SVW
so

  TU          ST
------- = ---------- (as you know SV = ST + TV  = 12 + 18 = 30)
  VW       SV
so
  TU          12
------- = ---------- 
  40          30

TU = 12 * 40 / 30
TU = 16

answer
16 inches

Write the following expression without negative exponents and without parentheses.
jeka94

Answer:

1/10x * 1/10x

Step-by-step explanation:

Writing a term with negative exponents is the same as putting it in a fraction.

10x^-1 = 1/10x

so the expression would be

1/10x * 1/10x

Remember that the general decay equation is:
y=A(1-r)^{x}
where 
y is the amount after a time x
A is the initial amount 
r is the the decay percent in decimal form

The first ting we are going to do is find r by dividing our <span>decay rate of 25% by 100%: </span>r= \frac{25}{100} =0.25.
We also know from our problem that y=64. Lets replace y and r in our formula:
64=A(1-0.25)^{x}
64=A(0.75)^{x}
We know now that our decay rate is 0.75, and since 0.75<1, we can conclude that this situation represents exponential decay.

Now, to find the initial amount, we are going to solve our equation for A:
64=A(0.75)^{x}
A= \frac{64}{0.75 ^{x} }
Notice that A will depend on the number of ours x. <span />
