Answer:
∠ R = 75°
Step-by-step explanation:
you are correct with answers to a, b, c
d
the sum of the 3 angles in Δ QRS = 180° , that is
∠ Q +∠ R + ∠ S = 180° , so
55° + ∠ R + 50° = 180°
∠ R + 105° = 180° ( subtract 105° from both sides )
∠ R = 75°
Answer:
Statement expressed by Trent is RIGHT.
Step-by-step explanation:
Here, the given expression is:
( to show) :
Now, as we know by DISTRIBUTIVE PROPERTY:
A (B + C) = AB + AC
Consider the RHS of the expression:
(p +30)(p+0) = (p +30)(p) ............ ( a + 0 = a for all a)
Simplifying (p +30)(p) by distributive property, we get:
⇒ Left side = Right side
Hence, statement expressed by Trent is RIGHT.

Answer:
There is a 33.3% chance you will pull a red marble after pulling a blue one.
Step-by-step explanation:
There are a total of 10 marbles in the sack. A blue marble is removed from the bag without being replaced, leaving 9 in the sack. 3 of the marbles left are red. To find the probability of pulling a red marble, we divide the number of red marbles by the number of total marbles.
3/9 = 1/3 = 0.333 = 33.3%
The number is 225.
It square roots are +15 and -15 .
They are 30 apart on the number line.
