\text{Find the perimeter of the track field}\\\\\text{We already have one of our outside value, 50. We can multiply}\\\text{this by 2}\\\\50\cdot2=100\\\\\text{Now we need to find the perimeter, better known as the circumference}\\\text{of the half circle}\\\\\text{Since there is two half circles, we can make one}\\\text{whole circle}\\\text{Use the equation:}\\\\C=\pi \cdot d\\\\\text{Plug in and solve:}\\\\C=\pi \cdot 30\\\\C=94.24778\\\\

\text{Add 100 and 94.24778}\\\\100+94.24778= 194.24778\\\\\text{Round to the nearest hundredths place:}\\\\\boxed{\text{194.25 m}}

podryga [215]

Answer:

0.375, 0.125, 0.5

Step-by-step explanation:

given that you are taking a T/F exam and you have no idea at all about the answers to the last three questions.

Probability for correct guess = 0.5 remains constant for each of the three questions

X - no of questions is binomial with n =3 and p = 0.5

1) the probability that you guessed right on exactly one of the three questions

= P(X=1)

= 3C1(0.5)^3 = 0.375

2) the probability that you guessed right on zero of the three questions

= P(X=0)\\= 0.5^3=0.125

3) the probability that you guessed right on at least two of the questions

=P(x=3)+P(2)\\= 1-0.5\\=0.5

Two different things u can do
Substitution:
X-9y=12
+9y +9y
X=9y+12

-3(9y+12)+9y=36
-27y-36+9y=36
+36 +36
-18y = 72
/-18 /-18
Y = -4


Or whatever this other I’ve is called

-3x-9y=36
-1(X-9y)=(12)-1

-3x-9y=36
-x+9y=-12

-4x=24
X= -6

natali 33 [55]

Answer: 30, -36, 42

Step-by-step explanation:

So basically the pattern is just the next number that is a multiple of six, but every other number is negative. 6 is 6 times 1, -12 is 6 times -2, 18 is 6 times 3, -24 is 6 times -4, 30 is 6 times 5, -36 is 6 times -6, and 42 is 6 times 7

Need help with 2 and 3 and express I’m radical form
kondaur [170]
This is just simple Pythagorean’s theorem. a^2 + b^2 = c^2

Number 2:
5^2 + x^2 = 10^2
25 + x^2 = 100
x^2 = 75
x = sqrt 75 = 5*sqrt(3)

Number 3:
4^2 + x^2 = 7^2
16 + x^2 = 49
x^2 = 33
x = sqrt 33
