The first one is finding the square root of things I believe and I'm not sure about the second one sorry
Answer:
Positive correlation.
Step-by-step explanation:
The miles per hour increases as the cycling speed increases.
Answer:
Yes, they are congruent by SAS postulate.
Step-by-step explanation:
Let us first name the vertices of both the triangles.
The labelled diagram is shown below.
Consider the triangles ABC and ACD
Statements Reasons
1. BC ≅ AC Given
2. ∠ ACB ≅ ∠ CAD Given
3. AC ≅ AC Common sides are congruent due to Reflexive property
As two corresponding sides and the included angles between them are congruent, therefore the two triangles are congruent by SAS postulate.
So, we can conclude that the given triangles are congruent.

Fraction = 19/500
You can't write it as a mixed number
Mixed numbers have to have whole numbers.
19/500 is less than 1, therefore it cannot be a mixed number.
