First we will find the square root of the square with the added sides to find the side + 5.
√85 = 9.219
∴ Original side = 9.219 - 5 = 4.219 cm

the current temperature in small town - 20 degrees Fahrenheit this is 6 degrees less than twice the temperature that was six hou

Vlad [161]

For problems like this we can use algebra to help us, the farenheight 6 hours ago was:
(2xt)-6=-20
We have to balance the sides out, first we minus 6
2xt=-26
Now we can divide by 2
t=-13

We now know the temperature 6 hours ago was -13

Solve the equation for [0,2pi]<br> cos2x=1/sqrt2

lapo4ka [179]

$cos(2x) = \frac{1}{\sqrt{2}}$
$cos(2x) = \frac{1}{\sqrt{2}} * \frac{\sqrt{2}}{\sqrt{2}}$
$cos(2x) = \frac{\sqrt{2}}{2}$
$cos(2x) = cos(45)$
$cos(x) = cos(22.5)$
$x = 22.5$

The Decimal System Uses 10 Symbols To Represent Numbers True or false

lutik1710 [3]

Answer:

For non-negative integers yes, it's 10 symbols.

Step-by-step explanation:

The symbols are the digits! 0, 1, 2, 3, 4, 5, 6, 7, 8, and 9.

Please note, that to represent negative numbers we use an additional symbol - and a . for fractions. I'm pretty sure the question is about the basics of the decimal system and the ten digits though.
