Let "n" be a number

9 + 3n = 57
3n = 57 - 9
3n = 48
n = 48/3
n = 16

Charlotte spent 1/2 of the day shopping at all. She spent 1/4 of this time trying on jeans. What fraction of the day did Charlot
RideAnS [48]

Answer:

Charlotte spend \frac{1}{8} of day trying on jeans

Step-by-step explanation:

Charlotte spent part of day on shopping = \frac{1}{2}

She spent part of shopping time on trying jeans =\frac{1}{4}

We are supposed to find What fraction of the day did Charlotte spend trying on jeans.

She spent fraction of the day in trying jeans = \frac{1}{2} \times \frac{1}{4}

She spent fraction of the day in trying jeans = \frac{1}{8}

Hence Charlotte spend \frac{1}{8} of day trying on jeans

Explain why ΔABC cannot be shown to be congruent to ΔCDA.
igomit [66]

There isn't enough info to prove the triangles to be congruent or not. So we can't say for sure either way.

We have angle CAD = angle ACB given by the arc markings, and we know that AC = AC due to the reflexive theorem. However we are missing one third piece of information.

That third piece of info could be....

  • AD = BC which allows us to use SAS
  • angle ACD = angle CAB which allows us to use ASA
  • angle ABC = angle CDA which allows us to use AAS (slight variation of ASA)

Since we don't know any of those three facts, we simply don't have enough information.

side note: If AB = CD, then this leads to SSA which is not a valid congruence theorem. If we had two congruent sides, the angle must be between the two sides, which is what AD = BC allows.
