Select all true statements after the transformations:
a. Angle A coincides with angle F.
b. Angle B coincides with angle D.
c. Segment AC coincides with segment EF.
d. Segment BC coincides with segment ED.​
e. Segment AB coincides with segment ED.

Answers

Answer: B.

C.

E.

Step-by-step explanation:

The true statements after the transformation, given that triangles ABC and EDF are congruent are: statements B, C, and E.

Recall what congruent triangles share in common:

If two triangles are congruent, all three sides of one triangle will be congruent to all corresponding three sides in the other triangle.If two triangles are congruent, all three angles of one triangle will be congruent to all corresponding three angles in the other triangle.

Thus, if triangle ABC is congruent to triangle EDF, then Kiran will know that after the transformation:

<A will coincides with angle E<B will coincides with angle D<C will coincides with F

Segment AC will coincides with EF, AB to ED, as well as BC to DF.

Therefore, the true statements after the transformation, given that triangles ABC and EDF are congruent are: statements B, C, and E.

Marcos deposited $500 into a 2.5-year simple interest account. He wants to earn $50 interest. What interest rate must the account pay?

Answers

The account must pay a 40 percent interest rate under Marcos.

A basic interest account is what?

A loan's or deposit's initial principal serves as the foundation for simple interest.

Contrarily, compound interest is calculated based on both the principal amount and the interest that is accrued on it each period.

Simple interest is simpler to compute than compound interest because it is just applied to the principal.

Compare the slopes m1 & m2 of the lines to determine if the lines are parallel, perpendicular or neither.

Answers

Answer:

In order top to bottom: perpendicular, parallel, neither

Step-by-step explanation:

For lines to be perpendicular, their slopes must be the opposite reciprocals of each other. That means the fraction is flipped and the sign is flipped. For the first one it's 3/4 and -4/3 which is opposite reciprocals.

For lines to be parallel, the slopes are the same. The second one has both slopes = 1/2.

The last one is neither because it's not equal and they're not opposite reciprocals.

I recommend graphing these if you're still having trouble with the concept. You can try desmos.com, that's a good website to use.
