- About 127.3(square root of 16,200, or 90√2) Look at this problem like a right triangle. Each leg is 90 feet, so the hypotenuse is the square root of 90^2 + 90^2
- About 52.3(square root of 2735.64) Another right triangle problem! Once again, with Pythagorean theorem (a^2 + b^2 = c^2) You can deduce that 60^2 = 29.4^2 + the width of the TV^2.
- About 11.6(Square root of 134.75)Another right triangle problem, you can deduce that 9.5^2 + The pool length^2 = 15^2
Hope it helps <3

use this
Step-by-step explanation:
velocity = distance / time…. So distance = velocity x time
23/8= 2.875
2.875 multiplied by 3= 9 people want an ice cream party
23-8= 14 people want a pizza party
Answer:
The amount $15000 is divided as
in 2% = $7000
in 5% = $8000
Step-by-step explanation:
It is given that the total amount is $15000 and rates of interests are 2% and 5%.
<em>Let the amount invested in 2% be "x", so the amount invested in 5% is (15000 - x).</em>
The annual interest on x part is given as,
=
Similarly, The annual interest on (15000 - x) part is given as,
=
the total annual interest is given as $540
Thus, <em>540 = </em>
<em>54000 = </em>
<em>21000 = 3(x)</em>
x = = 7000
Thus the shares are $7000 and (15000 - 7000) $8000 .
