Answer:
Y=13
Step-by-step explanation:
X is 45 so
45+5y+5=9y-2 solve and y=13
Answer:
y = 13
Step-by-step explanation:
x + 135 = 180 {linear pair}
x = 180 - 135
x = 45
9y - 2 = 5y + 5 + x {Exterior angle property of triangle}
9y - 2 = 5y + 5 + 45
9y - 2 = 5y + 50 {Subtract 5y from both sides}
9y -5y -2 = 50
4y - 2 = 50 {Add 2 to both sides}
4y = 50 + 2
4y = 52 {Divide both sides by 4}
y = 52/4
y = 13

Jordan uses 1/4 of the 31/2 yards of fabric she has to make a top. How many yards did she use?
Answers
The fabric left is 2 1/4 yards which is calculated using subtraction.
Total fabric = 3 1/2 = 7 / 2 yards
Used fabric = 1 / 4 yards
Fabric left will be calculated using subtraction.
So, we get that:
Left fabric = 7 / 2 - 1 / 4
= 14 / 4 - 1 / 4
= 13 / 4
= 2 1/4 yards.
Therefore, we get that, the fabric left is 2 1/4 yards which is calculated using subtraction.

The formula to determine the period of one swing of a simple pendulum is T=2\pi\sqrt{\frac{L}{g}},T=2π g L , where LL is the length of the string and gg is the acceleration due to gravity. Solve the formula to solve for LL in terms of \pi,π, TT and g.G.
Answers
Answer:
L = (T² × g) / 4π²
Step-by-step explanation:
T = 2π√L/g
Where,
L = length of the string
g = acceleration due to gravity
T = 2π√L/g
square both sides of the equation to eliminate the square root
T² = (2π)²√(L/g)²
T² = (2π)²(L/g)
(2π)²
= 2π × 2π
= 4π²
T² = 4π²(L/g)
Multiply both sides by g
T² × g = 4π²(L/g) × g
T² × g = 4π²L
Divide both sides by 4π² to get L
L = (T² × g) / 4π²

In uniform probability distributions, the likelihood of each possible outcome happening or not is the same. This property means that, for any given trial, the probability that an event will be successful does not change. Take the probability of rolling a 5 on a die for instance, no matter how many trials are performed, there is always a 1 in 6 probability for each trial.

(pre-calc) Use Limit Laws to determine the limit of a(n). It is not -∞, so what answer is it and why?
Answers
The limit of the function as the variable n tends to minus infinity is -1
Limit of a functionGiven the limit of a function expressed according to the equation;
a(n) = 6n²-n-3n³/3n³+n-1
The value of the function if n tends to minus infinity is expressed as show:
a(n) = 6n²-n-3n³/3n³+n-1
Divide both all the terms by n³
a(n) = 6n²/n³-n/n³-3n³/n³/3n³/n³+n/n³-1/n³
a(n) = 6/n-1/n²-3/(3+1/n²-1/n³)
a(n) = 6/-∞ - 1/(-∞)²-3/(3+1/(-∞)²-1/(-∞)³)
a(n) = -3/3
