Rectangle RSUT has diagonals that meet at point x.
Stels [109]

Answer:

x=12.5

y=10

Step-by-step explanation:

Properties of rectangle:

  • Opposite sides are congruent
  • All angles are right angles
  • Diagonals bisect each other
  • Diagonals are of equal length

so from the properties we came to know that diagonals bisects each other and diagonals are of equal length  

Given Rectangle RSUT has diagonals that meet at point X.

⇒RX=SX=UX=TX=\frac{1}{2}RU=\frac{1}{2}ST

⇒RX=\frac{1}{2}ST

⇒4x=\frac{1}{2}(100)

⇒x=12.5

Also XU=RX

⇒(4)(12.5)=5y

⇒5y=50

⇒y=10

Lea and her father arrived at the scenic overlook 15 minutes before noon and left 12 minutes after noon using am or pm write the
Aneli [31]

Answer:

They arrived at am and left at pm

Step-by-step explanation:

What do you need to find?

We need to find the time when Lea and her father arrived at the scenic overlook and the time when they left.

What do you need to find first?

First we need to find the exact minutes they arrived and left. Then we have to determine whether it was am or pm

Steps:

1. Noting the time they arrived

   They arrived 15 minutes before noon

2. Determining whether it was am or pm

   Noon is 12 pm by convention

   Midnight is 12 am by convention

3. Calculating the minutes for exact time

Each hour has 60 minutes:

60 - 15 = 45

4. Determining the time(am or pm) after subtracting 15 minutes

which means they arrived at 11:45 am (am is used for time before 12 at noon)

5. They left 12 minutes after the noon:

    Noon time is 12 pm

6. Adding 12 minutes to 12pm

    The exact time becomes 12:12pm
