What ? What ?
Did you write the first two answers in pencil ?
They're correct ! Just do the other two exactly the same way.
-- Do the division problem printed in the "Distance ..." column.
-- Multiply the answer by 0.1 .
-- Write the new answer in the last column.
Answer:
11/15
Step-by-step explanation:
To find probability, you divide whatever you're looking for over your total. In this case, you have 11 marbles that are not red, and 15 marbles total, so your answer would be 11/15.

The cable increases by 20 in addition to the length of cable needed
Answer:
x = 13
Step-by-step explanation:
Answer:
x = 25°
m∠B = 65°
m∠C = 50°
Step-by-step explanation:
We know that a triangle's angles will be equal to 180;
65° + (3x - 10)° + (2x)° = 180°
3x° + 2x° - 10° = 115°
5x° = 125°
x = 25°
Now we can plug our x value into the expressions for ∠B and ∠C;
[B] 3x° - 10° becomes 3(25)° - 10° = 75° - 10 = 65°
[C] 2x° becomes 2(25)° = 50°
We can also check our work;
65° + 65° = 130°
130° + 50° = 180°
Have a nice day!
I hope this is what you are looking for, but if not - comment! I will edit and update my answer accordingly.
