Answer:
82
Step-by-step explanation:
2*5 + 9*8 = 10 + 72 = 82
First, we want to find the GCF of 15 and 21, which is 3. Now we do 15 divided by 3 and 21 divided by 3, which gives us 5 and 7. To rewrite the expression, we take the GCF and put it on the outside of the parenthesis. Inside the parenthesis, we put 5 + 7. So it'll look like this:
3(5 + 7)
Answer:
Step-by-step explanation:
we have the points
(-9,7) and (-6,-3)
step 1
Find the slope
The formula to calculate the slope between two points is equal to
substitute the values
step 2
Find the equation in point slope form
we have
substitute
---> equation in point slope form
step 3
Find the equation of the line in slope intercept form
we have
Isolate the variable y
Distribute right side
subtract 3 both sides
Answer:
Yes, Kedir made profit.
Step-by-step explanation:
0.30 x 200 = 60 Birr
60 Birr is more than 50 Birr
He made profit of 10Birr, which is 20% of 50 Birr
Total number of marbles in the bag =20
Number of blue marbles =4
Now we just want two blue marbles out of four.
Probability of taking out first marble which is blue =4/20
Now after we took out one blue marble , number of blue marbles left are 3.
Probability of taking out second marble which is blue =3/20
Total probability = 4/20 *3/20 = 12/400
So probability of taking out two blue marbles is 0.03 or 12/400.
