both of them divisible by 9
Answer:
40 problems in 100 minutes
Step-by-step explanation:
This is a ratio problem.
You first divide 30 minutes by three to get how many problems she can do in 10 minutes. What you do to one side you do to the other side. So then, you should have 4 problems in 10 minute. Then, you multiply 10 by 10 and 4 by 10 to get 40 problems in 100 minutes.
Answer:
16/25 = 0.64 = 64%
Step-by-step explanation:
If we want the probability of Fiona waking up before 8am for at least one of the days, we can calculate the probability of she not waking up 8am in both days, and then we do 1 minus this probability.
The probability of she not waking up 8am in one day is (1 - 2/5) = 3/5
The probability of she not waking up 8am in both days is 3/5 * 3/5 = 9/25
So, the probability of Fiona waking up before 8am for at least one of the days is (1 - 9/25) = 16/25 = 0.64 = 64%
Both answers are C for #4 and #5
The equation of a line that passes through the point (x1,y1) and has a slope of m is
y-y1=m(x-x1)
so
we see that the slope is rise/run=3/4
3 points we see are (-4,-6), (0,-3) and (4,0)
we get the equations
y+6=3/4(x+4)
y+3=3/4(x+0)
y+0=3/4(x+4)
answer is the first equaiton
y+6=3/4(x+4)
