Answer:

180

Step-by-step explanation:

the original price * 80% = 144

Change to decimal form

the original price * .80 = 144

Divide each side by .80

the original price * .80/.80 = 144/.80

the original price =180

I would invest $500 to be compounded as Compound Interest is $1,540,250 while Simple Interest is $50.

<u>Step-by-step explanation:</u>

Step 1:

Calculate simple interest in the first case. Given details are Principal (P) = $500, Rate (R) = 5% and Time (T) = 2 years

⇒ Simple Interest (SI) = PRT/100 = 500 × 5 × 2/100 = $50

Step 2:

Calculate compounded interest for the second case. Given details are Principal (P) = $500, Interest rate (r) = 3%, Number of times it is compounded (n) = 12, time (t) = 2 years

⇒ Compound Interest (CI) = [P (1 + r/n)^n × t] - P

⇒ CI = [500 (1 + 3/12)^12 × 3] - 500

⇒ CI = [500 (1 + 1/4)^36] - 500

⇒ CI = [500 (5/4)^36] - 500

⇒ CI = [500 × 3081.5] - 500 = 1540750 - 500

⇒ CI = $1,540,250

The measures of the angles of a triangle add up to 180 degrees.
<span>This is true of all triangles.


You have two given angles of triangle PQR.
They are 24 degree and 100 degree.
<span>What do those measures add up to?


</span><span>What is 100 + 24? = 124


</span>
When you add the measure of the third angle to 124, you must get 180.
To find the measure of the third angle, just do 180 - 124.
<span>What do you get?



</span>
180 - 124 = 56
That means the third angle of triangle PQR measures 56 deg.
Now we know the measures of all three angles of triangle PQR: 24, 100, 56.
Triangle RST has two angles that measure 24 deg. and 56 deg.
<span>Since two angles of triangle PQR are congruent to two angles of triangle RST, the triangles are similar.</span>

A runner runs 400m west then changes direction and runs 600m south, If the entire trip takes 35s, what is the average speed? Giv
djverab [1.8K]
<h3>Explanation:</h3>

Average Speed = Total Distance / Total Time

Total Distance = 400m + 600m = 1,000m

Total Time = 35s

Average Speed = 1,000/35 = 28.57 m/s (approx.)

<h2>Answer:</h2>

Average Speed in two decimal places is <u>28.57 m/s (approx.)</u>

What is the area of this semicircle if the radius is 6m?
nlexa [21]
Semicircle = half area of circle
Area of circle: pi * r^2
pi = 3.14, r = 6
3.14 * 6^2 = 113.04/2 = 56.52
The area of the semicircle is 56.52 m^2
