8^2 = 64

3 + 11 × 64

Step 2: Solve Multiplication

3 + 11 × 64

11 × 64 = 704

3 + 704

Simon opened a certificate of deposit with the money from his bonus check. The bank offered 4.5% interest for 3 years of deposit

andrezito [222]

Answer:

$650

Step-by-step explanation:

To find the amount that Simon deposited to get $87.75 in time, we need to use the formula:

$I=Prt$

Let's break down our variables first.

P = ?

r = 4.5% or 0.045

t = 3

I = $87.75

Now let's plug our values into the formula.

$I=Prt$

$87.75=P(0.045*3)$

$87.75=P(0.135)$

To find P we need to divide both sides with 0.135.

$\dfrac{87.75}{0.135}=\dfrac{P(0.135)}{0.135}$

$P=650$

This means the Simon deposited $650 to open the account.

What conditions would be enough to prove that P is the circumcenter of HJK ?

BlackZzzverrR [31]

Answer:

Option A and C

Step-by-step explanation:

Explanation for why I choose option A :-

If you look at the triangle, HK has a midpoint of point L, HJ has a midpoint of point M, and KJ has a midpoint of point N. Now if you stretch the lines inside of the triangle, they intersect at point P which is known as the circumcenter of HJK, true.

Explanation for why I choose option C :-

Now let us look at the lines stretch inside of the triangle. There are three lines which are congruent. Those lines are PK, HP, and PJ (they are the big lines inside the triangle) are congruent. Since those three line intersect at point P, it make the statement true that P is the circumcenter of HJK.

Why option B is not an answer?

We do not know the third line (PN) measurements to find that if the three lines (PL, PM, and PN) are congruent and equal 90⁰. Since we do not know, it would not prove that they are congruent and P is the circumcenter of HJK.

Why option D is not an answer?

Well it says that triangle HJK is an acute triangle which is true, but this doesn't prove that P is the circumcenter of HJK.

I hope this helps, thank you :) !!
