Answer:
V=140
Step-by-step explanation:
5*4=20
20*7=140
It's 6.4 because 6.1 goes into 39.04 evenly 6.4 times. Hope this helps!
Answer:
x < 12.5 but see below. This is not a straight forward question.
Step-by-step explanation:
Inequality
3.20x < 40
Solution
Divide by 3.2
40 / 3.2 x < 12.5
Here's the question. What do you do with the 0.5? If you think she can buy 1/2 a yard (I think she might be able to in most places stocking bolts of material), then the 0.5 stays.
If you think she can only buy whole yards, then the answer is 12. Since the question does not make it clear, I would go with 12.5 yards. If it marks you wrong then you go with 12.
The question is an inequality. She has to buy less than 12.5

Given information
--------------------------------------------
Red balls = 6
Green balls = 5
--------------------------------------------
Find total
--------------------------------------------
Total balls = 6 + 5
Total balls = 11
--------------------------------------------
Find probability
--------------------------------------------
G = green
R = red
P (R+ G + G) = 6/11 x 5/11 x 5/11 = 150/1331
P (G +R + G) = 5/11 x 6/11 x 5/11 = 150 /1331
P (G +G + R) = 5/11 x 5/11 x 6/11 = 150 /1331
Total probability = 150/1331 + 150 /1331 + 150 /1331 = 450/1331
--------------------------------------------
Ans: The probability is 450/1331
