Answer:

B) four right angles

Step-by-step explanation:

The definition of a rhombus is that it is an equilateral quadrilateral.

This definition knocks out A.

C and D can also be knocked out because opposite angles are congruent, so they both must also be true.

Also, B is the requirement for a square, not a rhombus.

The decay of 192 mg of an isotope is given by A(t)= 192e-0.015t, where t is time in years. Find the amount left after 55 years.R
finlep [7]
This is a typical radioactive decay problem which uses the general form:

A = A0e^(-kt)

So, in the given equation, A0 = 192 and k = 0.015. We are to find the amount of substance left after t = 55 years. That would be represented by A. The solution is as follows:

A = 192e^(-0.015*55)
<em>A = 84 mg</em>

NEED HELP ASAP ON THIS QUESTION
andrew11 [14]

Answer:

None of these answers are correct.

Step-by-step explanation:

If a²+b²=c², then 7²+5²=c², then if you solve for c this equals about 8. This is none of the answers mentioned which is 8. Also, a good thing to remember is that the hypotenuse is always larger than the two side lengths. So, since the answer is 8 then it is none of the answers.
