Answer:

The first option is correct, 12/30 and 25/30

Step-by-step explanation:

To get common denominators, you need to find the GFC (greatest common factor) of 5 and 6, which is 30. Then you would need to make the fractions equal the same as the original fractions, by multiplying.

2/5 = ?/30 <- you can see that 30 is 6 times more than 5. so this means you multiply 2 by 6 to get 12. 12/30

5/6 = ?/30 <- you can see that 30 is 5 times more than 6. so this means you multiply 5 by 5 to get 25. 25/30

Lydia graphed ΔXYZ at the coordinates X (0, −4), Y (2, −3), and Z (2, −6). She thinks ΔXYZ is a right triangle. Is Lydia's asser
katrin [286]

Answer:

Option (4)

Step-by-step explanation:

Vertices of the triangle are X(0, -4), Y(2, -3) and Z(2, -6).

Slope of XY (m_{1}) = \frac{y-y'}{x-x'}

                            = \frac{-3+4}{2-0}

                     (m_{1}) = \frac{1}{2}

Similarly, slope of XZ (m_{2}) = \frac{-6+4}{2-0}          

                                   (m_{2}) = (-1)

m_{1}\times m_{2}=-\frac{1}{2}

Which should be (-1) if XY and XZ are perpendicular to each other.

Now we can say that XY and XZ are not perpendicular.

Therefore, Lydia's assertion that ΔXYZ is a right triangle is not correct.

Option (4) will be the answer.

Alonzo loaned jeremy $325.18 for 1 year at a simple interest rate of 12 5/8%. how much interest will jeremy have to pay?
gayaneshka [121]

Jeremy will pay $41.05 interest.

We know that, Interest = PRT/100

where,

P = principal

R = rate

T = time

For given question, principal (P) = $325.18

interest rate R = 12 5/8%

                        = 12.625%

And period T = 1 year

We need to find the interest.

⇒ Interest = PRT/100

⇒ Interest = (325.18 × 12.625 × 1) / 100

⇒ Interest = 4105.3975 / 100

⇒ Interest = $41.05

Therefore, Jeremy will pay $41.05 interest.
