Answer: B) 39</h3>
==========================================================
Explanation:
Equilateral triangles have three equal sides, ie the sides are all the same length.
Let's set sides ST and TU equal to each other and solve for x
7x-10 = 2x+25
7x-2x = 25+10
5x = 35
x = 35/5
x = 7
Then we use this to compute each side
- ST = 7x-10 = 7*7-10 = 49-10 = 39
- TU = 2x+25 = 2*7+25 = 14+25 = 39
- US = x^2 - 10 = 7^2 - 10 = 49-10 = 39
Each side is 39 units long, so this confirms we have the correct answer.
He will earn £360, for a total in his account of £1560.
The formula for simple interest is
I = prt, where I is the amount of interest, p is the principal invested or borrowed, r is the rate as a decimal number, and t is the amount of time. Using our information we have:
I = 1200(0.1)(3) = 360
This is the amount of interest. We add this to his original 1200 to get the total amount:
1200 + 360 = 1560.
Answer:
She paid $610.43
Step-by-step explanation:
multiply the original price by the decimal form of the percentage:
⇒ $789.90 x .25 (25%) = $197.475
subtract the product from the original price:
⇒ $789.90 - $179.475 = $610.425
round to the nearest hundreth:
⇒ $610.425 = $610.43
