Step-by-step explanation:
Answer:
p = 2.7x - 20
p(90) = $223
Step-by-step explanation:
revenue → f(x) = 3x ,where x is the number of downloads.
the statement “Your profit p is $20 less than 90% of the revenue for x downloads”
<u><em>means</em></u>

the profit for 90 downloads :
= p(90)
= 2.7×(90) - 20
= $223
Answer:
point N
Step-by-step explanation:
the closest perfect square to 82 is 81 which is 9
the closest perfect square to 99 is 100 which is 10
possible choices are N, P, or Q
since 81 is very close to 82, the answer is going to be very close to 9
answer would be point N
Answer:
48cm^2
Step-by-step explanation:
We can break the composite figure into two pieces.
We take the bottom rectangle and determine its area
The figure is 10 cm by 2 cm
A = 10*2 = 20cm^2
The height of the vertical rectangle is 9 cm -2 cm = 7 cm
The width is 10 cm - 6 cm = 4 cm
The figure is 7 cm cm by 4 cm
A = 7*4 = 28cm^2
The total area is the sum of the two areas
20 cm^2 + 28 cm^2 = 48 cm^2
Answer:
An inequality compares two values, showing if one is less than, greater than, or simply not equal to another value. Businesses use inequalities to control inventory, plan production lines, produce pricing models, and for shipping/warehousing goods and materials.
Step-by-step explanation:
Here's an example of a real world problem that's using inequalities.
Virena's Scout troop is trying to raise at least $650 this spring. How many boxes of cookies must they sell at $4.50 per box in order to reach their goal?
Let x = number of boxes sold. Then the inequality describing this problem is 4.50 ≥ 650.
We solve the inequality by dividing both sides by 4.50: x ≥ 144.44.
We round up the answer to 145 since only whole boxes can be sold.
Virena's troop must sell at least 145 boxes.
Then you should Check to make sure its correct:
If we multiply 145 by $4.50 we obtain $652.50, so if Virena's troop sells more than 145 boxes they will raise more than $650. But if they sell 144 boxes, they will only raise $648, which is not enough. So they must indeed sell at least 145 boxes. The answer checks out.
