Answer:
7/12
Step-by-step explanation:
To find the probability of drawing a blue marble you need to find how many marbles there are in total.
So you have to add 3 red marbles, 7 blue marbles, and 2 green marbles to get the total.
So 3 + 7 + 2 = 12
There are 12 marbles in total so now you have to find how many blue marbles there are.
There are 7 blue marbles out of 12 marbles.
Now you have to put this as a fraction to see if it can be simplified.
7/12 cant be simplified, so the probability of drawing a blue marble is 7/12.
Answer:
y=3x+(-3)
Step-by-step explanation:
y=mx+c
3=3(2)+c
3=6+c
c=-3
Explanation:
Since we have given that
There are 6 gray keys for every 11 black keys .
So, the ratio will be 6:11
Let the number of gray keys be 6x
Let the number of black keys be 11x
Now, according to question,
so,
If it takes that long to make one pair, then i’d say maybe 468 hours to make all 36 pairs
Answer:
90 degrees
Step-by-step explanation:
If two angles are supplementary they are a linear pair which means they form a straight line, and if you know a straight line equals 180 degrees which is the total degrees of a triangle.
Now if you have two supplementary angles and they are congruent that means not only are they right angles but its half of 180 so you divide these pair of 2 by 180 giving you your total of 90 degrees.
Have a nice rest of your day !
