Olivia is brewing tea. She starts boiling 0.455 L of water in a kettle. The change in volume of the contents of the kettle are noted below.

First, Olivia adds tea leaves. This increases the volume of the contents by 0.056 L.
After a few minutes of brewing, evaporation brings the volume down by 0.004 L.
Finally, Olivia pours herself a cup, which reduces the volume of the contents of the kettle by 0.168 L.
What is the volume of the contents of the kettle after Olivia pours herself a cup of tea?

0.227 L
0.287 L
0.339 L
0.347 L

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

it is contrapositive

i could not see the question too well so check yourself again too . this is because i want you to get it correct.

proofs involving isosceles triangles often require special consideration because an isosceles triangle has several distinct properties that do not apply to normal triangles.(more about triangle types) therefore, when you are trying to prove that two triangles are congruent, and one or both triangles, are isosceles you have a few theorems that you can use to make your life easier.

step-by-step explanation:

an isosceles triangle has two congruent sides and two congruent angles. the congruent angles are called the base angles and the other angle is known as the vertex angle. ∠bac and ∠bca are the base angles of the triangle picture on the left. the vertex angle is ∠abc
