Answer:

The average of students in the two classes who went on the field trip is \frac{17}{20}.

Step-by-step explanation:

Average = \frac{sum \:  \: of \:  \:observations }{no. \:  \: of \:  \:observations}

Average of students in the two classes =

\frac{ \frac{4}{5}  +  \frac{9}{10} }{2}

\frac{ \frac{8+9 }{ 10} }{2}

\frac{ \frac{17}{10} }{2}

\frac{17}{20}

Alex $8000 in a savings account that earns 3.25 % annually. How much will he earn in interest in 6 months?
kotegsom [21]
<h3>Answer:  $130</h3>

=======================================================

Explanation:

I'm assuming the bank is using simple interest (instead of compound interest).

If so, then,

i = P*r*t

i = 8000*0.0325*0.5

i = 130

The amount of interest is $130

In the formula above, I used

  • P = 8000 = amount deposited
  • r = 0.0325 = annual interest rate in decimal form
  • t = 6/12 = 0.5 years, which means you don't use t = 6. We don't use t = 6 because the interest rate is on an annual basis, and not a 6-month basis.

ABCD is a parallelogram. AB&gt;AD. Prove: m∠ADB&gt;m∠BDC. Show your work (statement reason maybe?)
Gwar [14]

In the parallelogram ABCD, join BD.

Consider the triangle Δ ABD.

It is given that AB > AD.

Since, in a triangle, angle opposite to longer side is larger, we have,

∠ ADB > ∠ ABD. --- (1)

Also, AB || DC and BD is a transversal.

Therefore,

∠ ABD = ∠ BDC

Substitute in (1), we get,

∠ ADB > ∠ BDC.
