Answer:

equal to

Step-by-step explanation:

The temperature at which a substance melts or boils is independent of mass, volume, or rate of heat change. So, a 10 g sample of butter will melt at a temperature that is equal to the melting point of a 5 g sample of butter.

50% of all the cakes jenny baked were party cakes, 1/5 were fruit cakes and the remainder were sponge cakes. What percentage of

anygoal [31]

So basically you want to find the total percentage of cakes that weren't sponge cakes first.

You already have the 50% of party cakes. For the 1/5 percent of fruit cakes, you can multiply it by 20/20, to get 20/100, and then just take the 20 to get 20% that were fruit cakes.

Now you can just add the percentages together.

50% + 20% = 70%

So now you know 70% weren't sponge cakes, out of 100%.

So here you can just subtract 70% from 100% to figure out the remaining part of 100%, which must be sponge cakes.

100% - 70% = 30%

So 30% of the cakes were sponge cakes.

43. If L is the midpoint of KN an MP, which methods can be used to prove the triangles are congruent

quester [9]

Answer:

Step-by-step explanation:

Two triangles are said to be congruent if all their corresponding sides and corresponding angles are equal to each other.

Given that L is the midpoint of KN an MP, hence:

KL = LN; and ML = LN

Also, ∠KLM = ∠PLN (vertical opposite angles are congruent to each other)

Since ∠KLM = ∠PLN, KL = LN; and ML = LN, we can hence say that triangle KLM and triangle LNP are congruent triangles using Side-angle-side (SAS) triangle congruency theorem.

The SAS theorem states that if two sides and one included angle of one triangle is equal to two sides and an included angle of another triangle, then both triangle are congruent
