Answer:
more than 5 sacks
Step-by-step explanation:
1 1/4 sack of flour per day
5 days
5 * 1 1/4
Change to an improper fraction
5 * (4*1+1)/4
5 * 5/4
25/4
Change to a mixed number
6 1/4 sacks
which is Marcella's age
of 63 is 21 ⇔ 63÷3=21
which is Justins age
Marcella's age⇒63
Justin's age⇒23
Aimee's age⇒42
Note: I was trying to find a better way to do this but I couldn't figure it out in the top of my head so I'm sorry for the long response
Answer:
Please check attached graph.
Step-by-step explanation:
Graph for the answer choices are missing but still we can solve this problem.
We can create graph of y=-x-3 first
then shade the graph for given inequality.
Comparing y=-x-3 with y=mx+b gives slope m=-1 and y-intercept b=-3
so we graph a point at (0,-3) for y-intercept.
then move the point 1 unit down and 1 unit right to reach point (1,-4)
Now join both points by a solid line because of equal sign of >=
this will give graph of y=-x-3
Now we determine direction of shading using any test point which is not on the line y=-x-3
say (0,0) is test point as it is not on the line y=-x-3
plug the test point into original inequality
which is true so the direction of shading will be in the direction of test point.
Answer:
B) 1/5
Step-by-step explanation:
P(R then Y) = 3/6 · 2/5 = 6/30 or 1/5 simplified
The average rate of change in a function from a to b is
.
For the left function, from x = 4 to x = 5, the rate of change is
.
For the right function, the rate of change is
Using a ratio to compare the right function's growth rate with that of the left function, you get .
The right function is growing approximately 21 times faster than the left function (over the interval from 4 to 5).
