Answer:
r ≥ 6
Step-by-step explanation:
4r≥24
r≥6
You can do this by finding the lengths of RT , RS and ST using the distance formula
RT = sqrt ((0- -5)^2 + (4 - -6)^2)
= sqrt (5^2 + 10^2) = sqrt 125
RS = sqrt ((-3- -5)^2 + (-2 - -6)^2))
= sqrt ( 2^2 + 4^2) = sqrt 20
ST = sqrt 125 - sqrt 20
RS / ST = sqrt 20 / (sqrt 125-sqrt 20)
so the ratio RS:ST = 2:3
Its B
Triangle BRM = Triangle KYZ
CPCTC ( corresponding parts of congruent triangles are congruent)
if two triangles are congruent then all of their angles and sides are congruent
Make sense?
Answer:
y and x because they need to be solved
Ok, so:
To do this problem, first, we assign variables.
Let x be the smaps that Many collected.
If Margie collegted 4 times as many stamps as Sam, Margie collected 4x stamps.
Then, we know that both of them have 210.
So x + 4x = 210.
Solving the equation:
5x = 210
And x = 42.
Many collected 42 stamps.
Now, we use the last fact to find how many stamps Margie collected.
Margie collected 4x stamps, that is 4(42), which is equal to 168 stamps.
Margie collected 168 stamps.
