How do I use the distance formula to determine whether two triangles are congruent

You find the distance of all sides to both triangle then match up the sides and see if they are similar

Given two triangles on a coordinate plane, you can check whether they are congruent by using the distance formula to find the lengths of their sides. If three pairs of sides are congruent, then the triangles are congruent vy the above theorem.

Jake sold 39 tickets to the the school fair and Jeanie sold 12 tickets. What is the ratio in the simplest for of the number of tickets Jeanne sold to the number of tickets Jake sold? a. 13/4

b.39/12

c.12/39

d.4/13

sorry if I am asking so many questions

Jake:Jeanie

39:12

39=3*13

12=3*2*2

so (3*13)/(3*2*2)

we can factor out the 3/3 or 1

so 13/4

jake:Jeanie is 13/4

39:12

39=3*13

12=3*2*2

so (3*13)/(3*2*2)

we can factor out the 3/3 or 1

so 13/4

jake:Jeanie is 13/4

the equation I=prt solves for the amount of simple interest a bank account receives after a certain period of time. I stands for interest, P is the principle, r is the percentage rate, and t is the time in years. If after six years seven thousand dollars earns $1,890 in simple interest, what is the percentage rate?

Answer:

The percentage rate is 4.5%.

Step-by-step explanation:

The given formula for simple interest is I=prt where I=simple interest, p=principle, r = percentage rate and t=time. In the problem, we are told that after six years (t=6), $7000 (p=7000) earns $1890 (I=1890). We can then substitute in the values for three of our variable to get the following: 1890 = (7000)(6)r. Multiplying 7000x6 = 42000 giving us 1890 = 42000r. Using inverse operations, we divide both sides of the equation by 42000 to get 0.045 = r. Since r = percentage rate, we need to multiply our decimal by 100 to find the percentage. 0.045 x 100 = 4.5%.

2.028241e+31 OK There are two ways

That could be a awnser (4 to the 52 power)

or it could be 52.

IF there was a a b c d awnser this would be easyer.

Hope it helps. If this done PLEASE MARK BRAINLYIST (I need 5)Step-by-step explanation:
