50 cm converted into inches is:
19.685.
Voila! Your answer.
Answer:
58100
Step-by-step explanation:
The way I see it is move the decimal point over to the right (or left depending on whether its negative or not) however many units the exponent says. After it moves over the number, add the zeroes for the remaining amount of spaces until you have moved it over the correct amount. I'm not sure if that made any sense, but I know the answer is correct.
Answer:
x = -4/3 and x = 5/2.
Step-by-step explanation:
6x² - 7x = 20
6x² - 7x - 20 = 0
To solve this, we can use the quadratic formula to solve this.
[please ignore the A-hat; that is a bug]

In this case, a = 6, b = -7, and c = -20.

= 
= 
= 
= 
=
= -8 / 6 = -4 / 3
=
= 15 / 6 = 5 / 2
So, x = -4/3 and x = 5/2.
Hope this helps!
Answer:P = Number of favourable outcomes ÷ Sum of total outcomes
So, Probability of drawing a blue sock is
Number of blue socks ÷ Number of total socks
= 6 ÷ 20
= 3 ÷ 10
= 0.3

Answer:
The area of the rectangle is 2820 square inches. The length is 60 inches. The width is 47 inches.
Step-by-step explanation:
Since we know the equation to find the width, we have to set them both to the perimeter of 90 inches. We will use the variable <em>x</em> to represent the length.
<em>x + x - 30 = 90</em>
<em>2x - 30 = 90</em>
<em />
You would then subtract 30 from both sides.
<em>2x = 60</em>
Divide by 2 on both sides, finding that the length (x) is 30 inches.
<em> x = 30 inches.</em>
<em></em>
Then, subtract 13 inches from the length to find your width.
<em>60 - 13 = 47 inches</em>
<em />
To find your area, you would multiply both of your factors (length and width) together.
<em> 60 x 47 = 2,820</em>
<em />
And those are your answers!
