∠1 and ∠2 are a linear pair. m∠1 = x - 29, and m∠2 = x + 61. find the measure of each angle. a) ∠1 = 74; ∠2 = 106 b) ∠1 = 74; ∠2 = 116 c) ∠1 = 45; ∠2 = 145 d) ∠1 = 45; ∠2 = 135

  about 5.6 days

step-by-step explanation:

we can fill the given information into the decay equation and solve for the value of t at which half the sample remains.

the half-life is about 5.6 days.

let x be the money she spent so that she can earn the free t-shirt.

since, she already spent $112.49

⇒

also, as per the statement: jennifer must spend $250 or more in order to qualify for a free t-shirt at the store.

then,

we have an inequality i.,e

subtract 112.49 from both sides we get;

therefore, $137. 51 more money does jennifer need to spend so that she can earn the free t-shirt
