Answer:
$0.27
Step-by-step explanation:
1/4 The ratio of meters of streamers to cost of streamers is 1 : 0.09
We want to know the ratio of centimeters of streamers to cost of
streamers.
2/4 We need to convert meters to centimeters.
There are 100 centimeters in 1 meter.
So, if 1 meter of streamers costs $0.09, then 100 centimeters of
streamers also cost $0.09.
3/4 The ratio centimeters of streamers to cost for 300 centimeters of
streamers.
Now, we can find an equivalent ratio to find the cost for 300
centimeters of streamers.
4/4 The streamers cost $0.27 per 300 centimeters.
Answer:
C. parallel lines
Explanation:
If two straight lines be at right angles to the same plane, the straight lines would be parallel.
To get the extrema, derive the function.
You get y' = 2x^-1/3 - 2.
Set this equal to zero, and you get x=0 as the location of a critical point.
Since you are on a closed interval [-1, 1], those points can also have an extrema.
Your min is right, but the max isn't at (1,1). At x=-1, you get y=5 (y = 3(-1)^2/3 -2(-1); (-1)^2/3 = 1, not -1).
Thus, the maximum is at (-1, 5).
Answer:
Step-by-step explanation:
She earns $8/hour
And she works weekend only
He is saving his earning to go for ski and it cost $190
For him to save $190, let know the hours he is going to work
He earns $8/hour and need $190,
Then he is going to work for
190/8=23.75hours
At least, he needs to work for 24hours and since the 24hours is in a day then, Becca his wrong, he doesn't need extra to work extra 6hours.
We are not told if he need to buy something or do something else we are only told he needs $190 for the trip
Answer:
25
Step-by-step explanation:
(y+2)^2=x
(-7+2)^2=x
(-5)^2=x
(-5)(-5)=x
25=x
Hope that helps :)
