Answer:
The experimental probability of the coin landing tails-side up is <u>60</u><u>%</u><u>.</u>
Step-by-step explanation:
The probability of it landing heads up is 4/10. You can use 4/10 to find how many times it landed on tails.
10/10 - 4/10= 6/10 now convert 6/10 into a percentage, 60/100=<u>60%</u>
2(4x+1) = 3x - 6x
8x + 2 = 3x - 6x
8x + 2 = -3x
-8x -8x
2 = -11x

-11 -11
x = -0.18
Answer:
132.5 inches
Step-by-step explanation:
The area of a triangle is 1/2 base height. the area of a rectangle is base height. Applying those principles gives us two equations: 8.5 x 10 / 2, and 9 x 10
then we have 42.5 and 90. in order to find the entire figure, they must be added so 42.5 plus 90 is 132.5. make sure to add the unit!
The longest side is the hypotenuse (10 cm ) and the leg is (8 cm) so since a leg is missing you subtract and make sure you square the numbers first , so 10cm(square it) - 8cm(squared) = 100-64= 36 then find the square root of 36 and that is 6 your answer is 6.
Complete the square: x^2 + 24x = 17
Identify the coefficient of x. It is 24. Take half of that coefficient: 24/2 = 12.
Now add the square of 12 to both sides of x^2 + 24x = 17
x^2 + 24x + 144 = 17 + 144
Write in factored form:
(x + 12)^2 = 161
Taking the square root of both sides:
x+12 = plus or minus
